Title: Power supply breaking system
Inventor: HARA AKITOSHI
IPC: G05F1/10
Filed: 1983-11-30
Abstract: PURPOSE:To prevent a fault due to the temperature rise within a housing and also to reduce the cost of a device by applying a common DC power supply only in case an AC power supply is given to an AC cooling fan within each housing and the temperature within the housing is lower than a normal level. CONSTITUTION:When an AC power supply is applied in a system, an AC switch 24 is first turned on for both a DC power supply housing 21 and a CPU housing 27 respectively. Then a switch detection sensor 26 detects that those switches 24 are turned on and sends a high-level signal to an AND circuit 31. Thus the conditions of the circuit 31 are released and the output of this circuit 31 is set at a high level. Therefore a DC power supply 22 works to supply the DC power to the housing 27 through a cable 32. In this case, the temperatures within both housing 21 and 27 are kept lower than a prescribed level. Therefore the output signal of a temperature sensor 25 is set at a low level, and the output signal of an OR circuit 30 is also set at a low level.

Title: Ignition device with no contact point for internal combustion engine
Inventor: NAKAMURA KATSUMI
IPC: F02P5/155
Filed: 1982-12-21
Abstract: PURPOSE:To prevent quenching and reversing by prohibiting the generation of an ignition signal based on the computation signal of a ignition lead angle until an angle signal is inputted when an internal-combustion engine is started. CONSTITUTION:A flip-flop 350 is reset when a power voltage is risen to V<+>, and its Q-output is 0. When the output of a comparator 200 is risen to 1 at an angle position thetaL, an ignition signal is outputted via an OR circuit 910 and the flip-flop 350 is set at the same time. Therefore, for starting, ignition is not given until the angle signal is outputted at the angle position thetaL. This construction permits to prevent quenching and reversing.

Title: High voltage pulse generating device, discharge lamp lighting device, lighting system and liquid-crystal projector
Inventor: TAKAYA MANABU
IPC: H05B41/18
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To improve the starting ability of a high-pressure discharge lamp. SOLUTION: A resistor 27 having a large withstand voltage at several 100Ω - several KΩ is interposed in the anode side of a diode 18 forming a voltage doubler rectifier circuit 26. Since the feedback current (ia) due to the oscillation of the discharge current of a capacitor 17 is restricted by providing this resistor 27, the oscillation due to the inductor of a high voltage transformer 22 is maintained for a long time. Since a large energy is thereby obtained as a whole, the sufficient glow discharge time of a high-pressure discharge lamp 23 is obtained after the dielectric breakdown so as to remarkably improve the starting ability of the high-pressure discharge lamp 23.

IPC: G08G1/0969
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To improve the safety of a vehicle by making it possible to suitably set permissible lateral acceleration while taking the state of a low-μ or high-μ road into account. SOLUTION: At a control part 2, a permissible lateral acceleration setting part 26 calculates a reference value ayl1 on the basis of a road surface μ and corrects the reference value ayl1 with a road gradient to obtain permissible lateral acceleration ayl2. A road surface friction coefficient correction part 26c further corrects the permissible lateral acceleration ayl2 corresponding to the road surface μ to obtain permissible lateral acceleration ayl3. This correction is made by multiplying the permissible lateral acceleration ayl2 by a road surface μ corresponding coefficient Kμ which is se to a smaller value as a road surface μ estimated value is larger and the safety margin is made larger for the permissible lateral acceleration as the road surface μ estimated value becomes larger.  This permissible lateral acceleration ayl3 is further corrected with the vehicle speed, a permissible entry speed is set by using the final permissible lateral acceleration ayl, and on the basis of the permissible entry speed as a criterion, warning and speed reduction control is performed as specified.

Title: Mos driver circuit
Inventor: SUZUKI YOSHIKAZU
IPC: H03K17/08
Filed: 1990-08-27
Abstract: PURPOSE:To prevent destruction of a MOSFET being a drive object by providing a level fixing means fixing a drive signal to 0 independently of an input signal to the driver circuit based on an external control signal so as to fix a logic level of a push-pull signal. CONSTITUTION:Since transistors(TRs) 54, 64 are turned on when an enable signal EN is inputted, a logic level of push-pull signals Sp1, Sp2 is fixed regardless of an input signal Sin. Then TRs 63a, 63c are turned off and TRs 63b, 63d are turned on and a drive signal Sout2 is stopped in a state of O. When the enable signal EN is inputted to a power supply circuit, the push-pull signals Sp1, Sp2. have a same phase and the logic level is fixed. Then both drive signals Sout1, Sout2 are stopped at a state of 0 and the operation is stopped. Thus, the drive of the MOSFET is blocked at the operation stop of the MOS driver circuit and destruction of the MOSFET is prevented.
