Title: Apparatus for cutting hot strip
Inventor: SUSUMU N
IPC: B23D25/12
Filed: 1980-10-24
Granted: 1982-04-19
Abstract: The shearing press for shearing hot rolled strip has shear blades(9,10) mounted on upper(7) & lower drums(8) resp.  The upper drum(7) is mounted in a bearing block(2) which runs in guides(5) which are inclined slightly to the vertical.  As the drums rotate, the upper drum is moved up & down in the guides by the hydraulic cylinder(16) acting through a lever(14) & link(12).  This causes the first shear blade(9) to move through an elliptical path which produces a clean sheared edge free from burrs.  The elliptical action also acts to separate the cut piece from the stock strip.

Title: Semiconductor device
Inventor: OKUMURA GOTSUYA
IPC: H01L29/45
Filed: 1987-11-20
Granted: 1990-11-03
Abstract: The semiconductor device includes a titanium nitride film (12) having a thickness of 1,000 Angstroms and serving as a nitrified high melting point film formed on P-type silicon substrate (10). An aluminium film (13) is formed on the titannium nitride film (12) and the titanium nitride film (12) is formed by chemical sputtering using a titanium target. Non-reacted titanium in the titanium nitride film (12) reacts with carbon to form titanium carbide (TiC) (16). the resultant structure is annealed at 500 deg.C for 30 minutes, and an increase in the lead current is not measured. Since titanium reacts with carbon at 200 to 400 deg. C, titanium and carbon are converted into titanium carbide (TiC) during annealing at 500 deg.C for 30 minutes.

Title: Secure personnel monitoring system
Inventor: BOWER DAVID S
IPC: G08B21/22
Filed: 1989-05-27
Granted: 1993-01-09
Abstract: A personnel monitoring system includes a tag (60) worn by each monitored person. The tag repeatedly emits digital radio signals, and a predetermined bit in the signal changes with time according to a predetermined pattern. Monitoring apparatus (12) detects the radio signals and sends an absence alarm signal if the signals cease. The monitoring apparatus detects spurious, forged signals which do not replicate the predetermined pattern of variation and provides a forgery alarm signal. The tag may be attached to the person by a strap bearing parallel electrical conductors. Attempts to remove the tag by severing the strap cause electrical contact between the conductors. Such contact triggers a detector, which in turn alters the radio signal.

Inventor: OH DON-SONG
IPC: H04Q11/04
Filed: 1990-12-15
Granted: 1993-07-16
Abstract: The time switch apparatus process 8192 time slots. The apparatus comprises multiplexer/demultiplexer units (1-4) for receiving differential data signal from subscriber subhighway and for transmitting data signal interchanged by time slots to subscriber subhighway, first time slot interchangers (5,7) for time slot interchange and line connection, a second multiplexer/demultiplexer (9) for sending output data of the time slot interchangers to local data link interface unit, a data link interface and testing unit (10) for inputting and outputting intermodule calls and service unit sub_highway data, and time slot interchangers (6,8) for executing time slot interchange function.

Title: Multi-detecting circuit of power source level
Inventor: KIM HYONG-SU
IPC: G01R19/165
Filed: 1991-01-16
Granted: 1993-11-29
Abstract: The  circuit  comprises  a  supply  voltage  level-detecting section (10) for outputting the level of supply voltage  (B+)  for detection, a detection-reference level setting  section  (20)  for outputting the level of detection reference voltage variably,  and operational amplifier (30)  for  comparing  the  level  of  supply voltage with detection reference voltage and outputting  detection signal.  The device  has  the  advantage  of  changing  detection reference voltage according to the change of supply voltage  level and may be used for products which have respective supply  voltage levels different from one another.
