Title: Elevator radio communication system
Inventor: INOUE TAKEHIRO
IPC: H04B3/60
Filed: 1991-07-09
Abstract: PURPOSE:To realize speech between a portable radio machine in a moving elevator and an external telephone set with a sufficient sensitivity. CONSTITUTION:When an elevator 1 is placed near an elevator hall and a portable radio machine 2 and a telephone set 6 speak to each other through a radio base station 4 in the elevator hall, the intensity of the electric field received by the radio base station 4 is weakened according as the elevator 1 is moved away from the elevator hall. An exchange 5 monitors the intensity of the electric field received by a radio base station 9 for elevator and switches a speech line from the radio base station, where the intensity of the reception electric field is reduced, to the radio base station 9 for elevator where it is high, thus continuing the speech. That is, the service area of the radio base station 9 for elevator is used to enable the portable radio machine 2 in the elevator 1 and the external telephone set to speak to each other.

Title: Flyback transformer
Inventor: KAWACHI MAKOTO
IPC: H01F38/42
Filed: 1986-08-20
Abstract: PURPOSE:To prevent fuming or explosion due to heat generation of a secondary winding, by adapting a transformer such that a material covering the secondary winding is melted by heat generation of the winding when a load connected to the secondary winding is short circuited so that the secondary winding is electrically contacted with a detection winding with which it has been mechanically contacted. CONSTITUTION:A light-load secondary winding 10 is covered and insulated with a material melted when heat is generated. A detection winding 11 is constituted by open wire or wire covered and insulated with a material thermally melted and is mechanically contacted with the winding 10. One end of the winding 11 is led out of a flyback transformer 12 and connected to a base of a transistor Tr23. If any defect is caused in a light load 21 and the load is short circuited, the winding 10 generates heat. The winding 10 is thereby layer-short circuited. Then, the layer-short circuited section of the winding 10 generates further heat, by which the material covering it is melted and the winding 10 is electrically contacted with the winding 11. As a result, an abnormal voltage from the winding 11 is detected with reference to a reference potential at the base of a transistor Tr24 and interrupts signal supply. Thereby, operation of a transformer 12 is stopped. In this manner, the transformer 12 is effectively prevented from fuming or exploding.

Abstract: PURPOSE:To drastically decrease the man-hour for production by providing a stage for etching a material layer for signal lines exposed from the openings of an insulating film which is used as a mask. CONSTITUTION:The laminate of the material layer of transparent pixel electrodes ITO1 and the material layer of the signal lines is formed successively over the entire area of a transparent substrate SUBS1 surface.

The conductive film exposed from the insulating film GI is selectively etched with the insulating film GI as the mask to expose the transparent conductive film ITO positioned in the lower part thereof. As a result, the original stage of forming the pixel electrodes by selectively etching the transparent pixel electrodes ITO1 to prescribed patterns is eliminated and the man-hour is correspondingly decreased.

Title: Control system of memory device
Inventor: IIJIMA KIYOKATSU
IPC: G11C11/34
Filed: 1983-10-18
Abstract: PURPOSE:To prevent destruction of the content of memory by synchronizing initial setting signals for column address strobe signals and row address strobe signals supplied to a metal oxide film semiconductor random access memory by a fresh request signal. CONSTITUTION:A POW-READY signal is shifted, and when there is RFST signal of refresh signal in minimum 16 mus (refresh interval), output of FF-4 and FF-5 becomes on, and an AND gate circuit 6 can take logic. The AND gate circuit 6 is shifted by FF-7 to avoid competition of refresh action of P-RST signal by RFST signal. A CLK signal of FF-7 is a clock signal from the system side, and when competition occurs with refresh action in case of shifting by an FF-7, the output can be shifted by a flip-flop circuit. Accordingly, signals such as outside noise etc. are synchronized in fresh cycle. As the pulse width is confirmed, small width is neglected, and does not come in by mistake during refresh action. Thus, the content of memory of the metal oxide film random access memory is secured and destruction can be prevented.
