Title: Snubber circuit in semiconductor power converter
Inventor: KOBAYASHI TADAO
IPC: H02M1/00
Filed: 1992-09-01
Abstract: PURPOSE:To reduce the power loss of a snubber circuit and improve the efficiency of a power converter, by providing in the discharge path of the snubber circuit the switch whereby the charge stored in a capacitor of the snubber circuit is regenerated on the side of the power supply of the power converter. CONSTITUTION:Switches SW1, SW2 comprising respectively self-arc- extinguishing type semiconductor switching elements are provided respectively in the discharge paths for discharging respectively the charges stored in snubber capacitors C1, C2. At this point, when a switching element Tr1 is turned off, the charge stored in the snubber capacitor C1 by a surge voltage is recovered to an electrolytic capacitor CO on the side of a DC power supply, by switching on the switch SW1 through the base signal applied to a switching element Tr2 which is turned on a dead time late for turning off the switching element Tr1. Similarly, the charge in the snubber capacitor C2 stored by turning off the switching element Tr2 is recovered to the electrolytic capacitor CO on the side of the DC power supply, by switching on the switch SW2 through the base signal of the semiconductor switching element Tr1.

Title: Synchronization detection circuit
Inventor: ASANO TOMOJI
IPC: H04L7/08
Filed: 1988-09-16
Abstract: PURPOSE:To prevent a waste data by one frame by using synchronization step- out protection means to take a prescribed stage of protection based on alternate '0/1' or alternate '1/0' generated by a 0/1.1/0 pattern generating means when a synchronization detection means enters the synchronization when synchronization step-out takes place. CONSTITUTION:A synchronizing detection means 50 monitors alternate '0/1' and alternate '1/0' of a frame pattern to establish synchronization and a 0/1.1/0 pattern generating means in the synchronization step-out protection means 80 generates a pattern of alternate '0/1' or alternate '1/0' when the synchronizing detection means 50 enters the synchronization. Then the protection at the synchronization step-out is taken and when the synchronization step-out is detected, an output means 120 outputs an asynchronous signal 4 and when the synchronizing detection means 50 enters synchronization, a synchronizing signal 3 is outputted through the processing. Thus, a pattern of either alternate '0/1' or alternate '1/0' receives established synchronization, the synchronization step-out protection is taken and no waste of even one frame is produced.

Filed: 1990-09-05
Abstract: PURPOSE:To prevent spinning accompanying the operation of a parking brake by switching a driving system from two-wheel-drive to four-wheel-drive if a parking brake is put on when a vehicle is in two-wheel-drive condition due to operation of an anti-lock control. CONSTITUTION:In an anti-lock controller, a modulator 12 is controlled by an ECU 9, based on signals detected by wheel speed sensors 10L, 10R, 11L, 11R installed to respective wheels and brake fluid pressure applied to each wheel is controlled so that the slip ratio of each wheel remains within an appropriate range. In this case, if a parking brake 13 is actuated during the anti-lock control, a parking brake 14 is turned ON, and a two-wheel-to-four-wheel-switching mechanism 8 is operated by the ECU 9 which detects the action of the brake 14, in order to carry out switching from the two-wheel-drive to the four-wheel- drive. Thus, the braking force of the parking brake 13 is transmitted to all the four wheels 1L, 1R, 2L, 2R, so that the spinning of a vehicle, which is caused by locking of a specific wheel on which the parking brake acts, can be prevented.

Title: Knocking detecting device of internal-combustion engine
Inventor: SAWAMOTO KUNIAKI
IPC: G01L23/22
Filed: 1982-12-29
Abstract: PURPOSE:To decide a knocking strength by calculating and correcting the energy of a knocking signal containing also vibration of an engine head in the explosion stage, and the energy of a valve seating signal caused by seating of a suction valve or an exhaust valve, out of a high frequency output of a cylinder internal pressure sensor. CONSTITUTION:When an internal pressure of a cylinder is varied, a pressure applied to an ignition plug 14 is varied, and as a result, a pressure applied to a washer type piezoelectric element is also varied, therefore, the internal pressure of the cylinder can be detected. A detecting output 13S proportional to the internal pressure of cylinder is generated from an internal pressure sensor 13. When knocking is generated, a variation of a high frequency internal pressure of cylinder is superposed. A band pass filter 19 fetches a high frequency component, and supplies it as a signal 19S to a full-wave rectifying circuit 20A. Energy of a knocking signal and a suction valve seating energy are measured by executing an integration in an integrator 20B. When an integrator output 20BS is held, a knocking strength deciding part 21 reads its output 20BS. A delay angle signal 22S is sent to an ignitor 11 of a distributor from a delay angle control part 22.

Abstract: PURPOSE:To bring an environment in a vessel into nitrogen enriched condition and prevent the oxidizing of foods and the like by a method wherein a nitrogen gas supplying device is operated when the concentration of oxygen, which is detected by an oxygen sensor, is higher than a predetermined value. CONSTITUTION:The concentration of oxygen in a vessel 1, receiving subsdances (foods and the like) necessary to be prevented from oxidizing, is detected by an O2 sensor at all times and when the concentration of oxygen in the vessel is exceeded a predetermined value, the signal of the sensor is transmitted to a control unit 5. The control unit 5 operates a nitrogen gas supplying device 3 by the signal. The control unit 5 operates a compressor 31 and opens valves 34, 35 simultaneously to supply compressed air to an adsorbing tower so as to adsorb nitrogen gas. Subsequently, the valves 34, 35 are closed, another valve 36 is opened and a vacuum pump 33 is operated, Then, the nitrogen gas, adsorbed by an adsorbing tower, is discharged out of adsorbent and is supplied into the vessel 1. The necessary amount of nitrogen gas is supplied into the nitrogen gas vessel 1 while controlling the adsorbing and removing operations of the nitrogen gas by the control unit. When the nitrogen gas is supplied into the vessel 1, air in the vessel, which contains oxygen gas corresponding to the displacement of the supplied nitrogen gas, is discharged out of a discharging valve 4 whereby the inside of the vessel becomes nitrogen enriched condition.
