Title: Steering control method for rear wheel for four-wheel steering vehicle
Inventor: KIDO TOMOYUKI
IPC: B62D5/04
Filed: 1992-01-30
Abstract: PURPOSE:To perform transition to 2WS as while holding running stability even when abnormality occurs to a rear wheel steering mechanism by stopping control of rear wheel steering after rear wheels are automatically returned to neutral by a control means when an overcurrent flows in an electric motor for steering rear wheels. CONSTITUTION:A rear wheel steering mechanism 10 is driven with the aid of an electric motor 28, and the electric motor 28 is controlled by a control means 29. When an overcurrent flows in the electric motor 28, a control means 29 first effects control so that the electric motor 28 is reversed. When the overcurrent is still generated, an off-relay 44 and an electromagnetic brake 31 is operated and the electric motor 28 is stopped. Meanwhile, when the overcurrent is still generated, an alarm is sounded after rear wheels are automatically returned to neutral, and the electric motor 28 is stopped and brought into an 2WS state. Thus, in addition to prevention of the occurrence of seizure owing to the overcurrent, running is effected in a 2WS state even when abnormality occurs to the rear wheel steering mechanism 10 and running stability can be held even in case of emergency arising.

Title: Charging system of power storing means
Inventor: TOYOMURA TAKASHI
IPC: H02J7/10
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To charge a power storing means at a temperature within a proper range which does not impose a burden on the power storing means by a method wherein the temperature of the power storing means is detected and the temperature is controlled in accordance with the detection output to control the charge of the power storing means. SOLUTION: The temperature of a power storing means (a battery, an electric double-layer capacitor, etc.) 1 used in a motor-driven vehicle, etc., is detected by a temperature detecting means 2. A temperature managing means 3 outputs a temperature control signal in accordance with the detection output of the temperature detecting means 2. A control means 4 controls the charge of the power storing means 1 in accordance with the temperature control output signal of the temperature managing means 3. With this constitution, even if the power storing means 1 is subjected to forcible cooling, heating, etc., it can be securely judged whether the charge reaches a desired storage value. Therefore, even if the temperature management is applied to the power storing means 1, the charge can be stored to the desired storage value without excess nor shortage.  As a result, the temperature of the power storing means 1 can be freely managed and the charging can be carried out within a proper temperature range.

Title: On-gate circuit for semiconductor switching element
Inventor: TADOKORO YUICHI
IPC: H03K17/73
Filed: 1986-01-27
Abstract: PURPOSE:To prevent the breakdown of a switching element by providing a steady on-gate current generating part for outputting a prescribed DC current in a control pulse signal input period and supplying it to a gate of the semiconductor switching element. CONSTITUTION:When a control pulse is generated from a control pulse generating circuit 7 and a current from a steady on-gate current generating part 2 is started to flow, even if a no prescribed voltage is applied between an anode and a cathode of a gate turn-off thyristor GTO1, when a main circuit current is started to flow to the GTO1 in a period of a control pulse, a voltage corresponding to a time differential value of a rise is generated between both electrodes of the GTO1. In such a case, when a Zener voltage of a Zener diode 12 is selected so as to be lower than a voltage between both electrodes, the diode 12 goes to an on-state, and the GTO1 is turned off normally. Accordingly, the GTO1 is migrated safely to an on-state without the possibility that the breakdown is caused by a power loss which is determined by the product of the voltage between both electrodes and the main circuit voltage.

Abstract: PROBLEM TO BE SOLVED: To detect an erroneous pole position signal, if any, by judging the rationality of a pole position signal corresponding to the pole position of a permanent magnet synchronous motor and an incremental signal corresponding to the rotational angle thereof thereby making a decision whether these two signals are correct or not. SOLUTION: An elevator comprises a pole encoder 8 delivering a pole position signal Pp depending on the pole position of a permanent magnet synchronous motor 1, and an AB phase encoder 9 delivering an incremental signal Ep corresponding to the rotational angle thereof. A control block 10 calculates a phase data θs by taking the pole position signal Pp into a phase calculating block 11 and corrects the phase data θs by taking in the incremental signal Ep. In this regard, phase shift θe of the phase data θs is outputted to a phase abnoramality decision block 18 where a decision is made that the phase is abnormal if the phase shift θe exceeds a specified value and the elevator is stopped and the abnormality is notified. According to the arrangement, safety of elevator system can be enhanced.

Abstract: PURPOSE:To reduce the capacity of the output-side smoothing capacitor of the title tester and, at the same time, to miniaturize the other circuits and elements by using a high-frequency alternating current as the alternating current inputted to a boosting transformer. CONSTITUTION:An inputted commercial alternating current(AC) is converted into a direct current(DC) by means of a rectifier 2 and smoothing capacitor CA. The DC is again converted into an AC by means of a switching transformer after it is switched by a switching element 4. Then the AC is again converted into an DC voltage by means of a rectifier 8 and smoothing capacitor CB and inputted to a DC-to-AC converter 10. The converter 10 incorporates a boosting transformer and sends an AC output G proportional to the DC input F. A high- voltage DC output H is obtained from the output G by means of a high-voltage rectifier 12 and smoothing capacitor CC. Since the DC-to-AC converter is composed of the DC-to-AC converter 10 and rectifier 12, the size of the smoothing capacitor can be reduced.
