High-Efficiency Double-Overhead Diesel Engine
Kia
Motors has developed a new engine. The 2.9-liter J3 is an DOHC (Double-Overhead Cam),
16-valve direct injection diesel engine with intercooler and turbocharger and was
specifically developed to meet future Korean and European environmental safeguards and to
satisfy consumer demands of fuel efficiency and high performance. The J3's HSDI (High-Speed Direct-Injection) in-house developed technology enables the engine to develop a
high-power output of 135 horsepower despite its relatively small displacement of 2.9
liters.
In
addition, the J3 utilizes the combustion method of direct injection, an established trend
in international small diesel engine design. The engine develops maximal thermal
efficiency through the use of a high-pressure fuel pump, while a vertically set nozzle
structure optimizes fuel spraying. The overall effect is improved output power and fuel
consumption, by 30 percent and 20 percent, respectively. The J3 was developed with the aim
of minimizing noise and vibration, a major demerit of existing diesel engines. Vibration
is reduced by the use of a symmetric cylinder block and a timing belt case and ladder
frame at the lower part of cylinder block. It also employs a balance shaft to eliminate
secondary inertial force. Meanwhile, operational noise is minimized by use of the
timing-belt drive method, and valve noise by an hydraulic lash adjustor.
The engine size is so compact that it can be used on small autos and recreation vehicles,
or small trucks and trailers. The J3 may well serve as a model for the world's auto
industry as it prepares for the exacting pollution control standards of the 21st century.

New 6000 Aluminum Alloys
Iljin
Co. has developed a new Al alloy by adding manganese to the conventional 6000 series to
improve its problems of low tensile strength and poor extrudability. The addition brings
out uniformally distributed fine Mn disperoids in the Al matrix which increases strength
and release stress concentration. Furthermore, additional tensile, strength is gained
through a normal manufacturing process but without the benefit of an aging process, so
making the end product more economic.
While, aging boosts tensile strength by 35 percent, the new alloy possesses a tensile
strength 20 percent greater than age-treated 6063 alloy. The new alloy is therefore
expected to substitute age-treated 6063, conventional alloys as well as mild steel in the
fields of transportation, construction and agriculture. It has received the KT (Korea
Technology) mark from the Ministry of Science and Technology and the EM (Excellence Mark)
by the Korea National Quality Bureau. Iljin began production of the new alloy last year
and aims to capture 10 percent of the domestic market in 1998.

Rament Aloewhitening
Rament
Aloewhitening is a whitening cosmetic based on aloewhite, an aloe vera derivative.
Existing whitening cosmetic components have a reaction mechanism which competitively
restrains the activation of tyrosinase, an enzyme which helps form melanin. Aloewhite has
a different reaction mechanism. It responds in a non-competitive fashion to produce a
better whitening effect with fewer applications, thereby producing the same cosmetic
effect more economically.
As
well as a whitening function, Rament Aloewhitening possesses moisturizing, protection and
anti-aging properties by virtue of its superior abilities in inhibiting the skin-darkening
phenomena. In a battery of safety tests, it has met every standard. In addition, it has
exhibited no change of appearance and physical property under various conditions of
daylight, heat, pH levels, etc. Because Rament Aloewhitening is produced from aloe vera
rind which is generally discarded during the processing of aloe vera, unit costs are
lowered giving the product a competitive price advantage in its field. Consequently,
prospects for exports of the finished product and its raw material look good.

Integrated Communications Program
By
using the SEROME Teleman 97 program in your personal computer, it's possible to perform
all the existing telephone functions such as ARS, telephone and fax. In addition, it
enables video communication/conferencing on the basis of the International
Telecommunication Union's (ITU) international standard for video communication, ITU-T
H.324. The program's database system, which stores messages and addresses, gives it the
potential to be used as the basis of an office automation program by installing it in your
PC to handle functions as telephone answering, automatic dialling and faxing.
Technologically similar to its predecessors H.320 used in ISDN and H.323 which supports
LAN, it is easily transferable.
This program has excellent compatibility with other products due to its compliance with
the ITU-T H.324 international standard governing video communication. Because existing
programs use different communication standards they often have low compatibility.
Interface
with the program is through the image of a mobile telephone dialling pad on the computer
screen. By embodying a wide range of functions, the integrated nature of the program
distinguishes SEROME Teleman 97 from others of its kind now on the market. Based on
Windows 95, the program facilitates a variety of communication services through selected
hardware. Through its adherence to the G3 fax protocol, it's possible with H.324 to
transfer images and send faxes of the highest quality. Additionally, there are convenient
telephone-type functions including volume control on the speaker phone, voice
amplification on the handset microphone, and redialing.

Winner 3A Hard Disk Drives
Samsung
Storage Division (SSD) released its Winner (WA3) 3.5" hard disk drive in August 1997
and has since been a marked success in the under-$1,000 consumer, desktop and SOHO PC
market. To minimize program risk and optimize the time-to-volume ratio of the
highly-leveraged Samsung ASIC controller during the WA3's development, company engineers
looked to the mature third-generation head disk assembly (HDA) of the Winner product
family as the development platform of the W3A.
The hard disk drive (HDD) in the W3A represents the next level of integration from the
previous generation of ATA/Disk Controller/Buffet Management/ECC blocks. To that
controller have been added the internal Digital Signal Processor (DSP) core and embedded
servo-control. The WA3 hard disk drive is of a thin film head design with capabilities
ranging from 1.27GB to 3.8GB. With a spindle speed of 5,400 rpm an <10msec seek time
and with idle power at 3.5W typical, these drives run cool and support the power modes of
Sleep, Standby, Idle and Read/Write/Seek. Other features include: PRML Read Channel, PIO
Mode 4, Multi-Word DMA Mode 2, Automatic/Host Power and Saving Mode, and the ability to
sustain 10gs of operating shock. Samsung's success with the WA3 is a step toward the
company's strategic goal of becoming one of the largest players in the world HDD market.
