Title: Line concentration and line distribution system
Inventor: KOBAYASHI HIROSHI
IPC: H04Q3/62
Filed: 1984-12-20
Abstract: PURPOSE:To make it possible to set up a resonable timing of signal transmission without a load for a central processor by controlling adequately a signal transmission timing which is obtained from a test signal of each line concentration/ distribution terminal and a transmission delay time measured by a return time of the test signal. CONSTITUTION:The central processor 1 transmits datum DO1, DO2-DOn inserting dummy datum with time-sharing to each line concentration/distribution terminal 2a, 2b-2n using a transmission line 4. The central processor receives the transmitted datum DI1, DI2-DIn which are sent out from line concentration/ disbrituion terminals 2a, 2b thru 2n with fixed timing at a transmission path 3 on a time-sharing. A signal a contains an addressing signal which indicates a line concentration/distribution terminal and a window frame to measure a delay time.

Title: Inverter circuit
Inventor: SHIMOKAWA TAKEHISA
IPC: H03K19/0948
Filed: 1990-10-05
Abstract: PURPOSE:To reduce current consumption at the time of AC operation without allowing a through current to flow by preventing PMOS and NMOS transistors(TRs) constituting a circuit to delay a gate input from being simultaneously turned on. CONSTITUTION:This inverter circuit is provided with a 1st PMOS TR M2 and a 1st NMOS TR M3 and a 2nd PMOS and NMOS TRs M1, M4 constituted so that an input signal S1 can be serially inputted to their gates without a load. Namely, the input signal S1 is directly inputted to the gates of the TRs M1, M4 and inputted to the gates of the TRs M2, M3 through respective resistors R1, R2. Thereby, the levels of the gates m2, m3 are raised with a certain delay from the gates m1, m4. Thereby, all the four TRs M1 to M4 are not simultaneously turned on and a through current does not flow in any case. Thus, power consumption at the time of AC operation can be reduced.

Title: Forced-feed type kerosene stove
Inventor: SHIRAI SHIGERU
IPC: F23D3/40
Filed: 1984-12-19
Abstract: PURPOSE:To be able to put the fire out at once by return back of kerosene in a vaporizer to a kerosene tank promptly by installing a feed fuel reversing device which is linked to the signal of a vibration detector that detects vibration or upset of a stove and changes the flowing direction of feed fuel from a pump at combustion time. CONSTITUTION:In case of vibration due to big earthquake or upset of a stove, the signal of a vibration detector 10 comes into controller 13 which drives promptly the feed fuel reversing device and the inlet and outlet of the pump is switched over. As the flowing direction of the feed pump is reversed, kerosene is returned back from feed pipe 8 to pipe 25 and kerosene in the groove 17 of the vaporizer and pipe 8 is almost all returned back to kerosene tank 1. As a result, only a small amount of kerosene in the vaporizer is burnt out and the fire is put off at once.

IPC: B60L9/18
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To increase the stability in controlling a PWM converter and not to make reactors generate unnecessary heat by short-circuiting each reactor with each unit switch connected parallel to them, when using a DC power supply from the converter in the structure of an AC-DC main circuit constitution. SOLUTION: Reactors 8a, 8b and unit switches 14a, 14b connected parallel to these reactors are arranged between a converter 6 and inverters 10a, 10b. When an AC-DC circuit changeover switch 4 is changed over to an AC circuit side, the unit switches are closed to short-circuit the reactors, which consequently increases the number of parallel connections of capacitor elements 7, 9a, 9b between the output side of the converter and the input side of the inverter to reduce a ripple voltage. Also, a ripple current of the DC output of the converter is lowered by increasing the total capacitance of the capacitors.
