Title: A.c.elevator control system
Inventor: KOMURO GAS
IPC: B66B1/28
Filed: 1980-06-12
Granted: 1984-03-07
Abstract: The AC elevator control system compares the actual speed of an elevator car with a speed command and control is made so that deviation between the actual speed and the commanded speed becomes zero. The speed command is so composed that deceleration of the elevator car is gradually decreased as the car approaches to a target landing position in the stopping operation of the elevator.  A motoring torque or a braking torque is additionally generated in dependence on a load on the car in a region close to the target landing position.

Granted: 1986-11-12
Abstract: This invention is related to a digital made pulsimeter. When a measured pulse number sets up value of an object, it informs us of the value registered by the device. It does so through an instrument which sets up an upper and lower value of an object. This pulsimeter is informed whether a pulse is in the normal range or  not. It is particularly informative because it gives us a measured value of both the upper and lower value of object. The above mentioned value of the object is set by the pushing switch (up & down)-fig 2-.

Title: Power steering system
Inventor: KOZUKA HAJIME
IPC: B62D5/06
Filed: 1984-02-01
Granted: 1989-05-02
Abstract: In a servo assisted power steering, a pump (1) delivers high pressure oil (Qo) to the steering mechanism.  A multiport valve (2) on the steering column is operated by the steering wheel to let high pressure oil into one or other of the ends of the actuator (3) which drives the steering mechanism.  A pressure regulator (12) and flow regulator (13) are included in the hydraulic circuit.  The flow regulator is influenced by a speed detector (14), and changes the oil flow to an aux. circuit (7d). With increasing speed the flow increases and restraining pistons (5,6) at each end of the actuator become increasingly effective, such that the torque can be exerted by the driver to turn the steering wheel.

Abstract: The carrier strip (1) for jig devices operated by impact force carries nails (2) which are accommodated at equal distances from one another in retaining holes (3). The nails (2) carry guide washers (6, 7) for guiding and for retention in the retaining holes (3). Stops (8, 9), for axially supporting the guide washers (6, 7), project into the unobstructed width of the retaining holes (3). The stop (8) on the seating direction side can be overcome under seating conditions for displacement of the nails (2) inside the retaining holes (3).

Title: Overheat prevention device for compressor
Inventor: LEE MYONG-RYOL
IPC: F04C29/04
Filed: 1990-12-29
Granted: 1992-09-09
Abstract: The overheat  prevention  device  is  installed  between  the evaporator (41) and the compressor inlet (12) to form a flow  tube (51) for refrigerent, one end (51B) connecting to  the  evaporator (42) and the  other  end  (51C)  to  the  suction  inlet  (12).  A plurality of radiator fins are attached to the tube (51) near  the end (51C) to facilitate heat radiation from the refrigerant in the tube; on the other hand, the tube is  covered  with  n  insulation tube (53) of low het conductive material to prevent the  influence from the heat  of  the  radiator  fins  and  the  atmosphere.  The prevention of overheating at  the  suction  inlet  of  refrigerant improves the performance of refrigerator.
