Filed: 1978-06-28
Abstract: PURPOSE: To make braking surer by installing an auxiliary control valve within a valve box of a device for a control valve integrally.  
     CONSTITUTION: An auxiliary control valve Va, equipped with a valve assembly 34 consising of a valve rod 35 having a pressure receiving piston 36, a valve chamber 30, an auxiliary otuput oil pressure chamber G, an auxiliary input oil pressure chamber G, an auxiliary input oil presure chamber F and a spring 37, is installed within a device for a control valve V provided in a second oil passage L 2 . When a master cylinder M is being operated, pressure-oil sent out of a second output port P 2  is flown into a damping chamber A through an input port 4 and is divided for a valve chabmer B and the auxiliary input oil pressure chamber F, thereafter, is provided to rear-wheel brakes Br throuth the auxiliary output oil pressure chamber G and an output port 5. When the pressure of the chamber G is attained to a predetermined valve, the valve assembly 37 descends against the spring 37 and shuts between both chambers F and G. Consequently, even when a weight valve 23 is operated prematurely and shuts a valve port 12 upon running down a steep slope, for example, the oil pressure generated by the master cylinder M is delivered to the rear-wheel brakes Br through the auxiliary control valve Va and a sure braking may be effected.

IPC: F23D14/18
Filed: 1987-03-31
Abstract: PURPOSE:To ignite easily and surely by a piezoelectric igniting means and burn the whole amount of mixture gas by combustion catalyst, by a method wherein mixture gas, including insufficient air, is produced immediately before ignition and flames are extinguished by a flame shut-off member. CONSTITUTION:When an ignition button 28 is depressed, the operation is transmitted to an air amount regulating member 30 through a connecting member 31 and the member is slid to close an atmosphere intake port 8 fully, thereafter, the member 30 closes a part of the intake port 8. According to this operation, the opening area of the intake port 8 is reduced to reduce the inflow amount of air whereby mixture gas, short in the amount of air and easy to ignite, is obtained. Accordingly, the mixture gas is ignited surely and flaming is generated in a flaming combustion chamber 12 whereby the temperature of the combustion catalyst 20 becomes the temperature of oxidizing reaction of the catalyst. Then, the pressing force exerted on the button 28 is released to close the intake port 8, then, flames are shut off immediately since all the air in the chamber 12 is consumed. After the flames are shut off, mixture gas, having the optimum mixing ratio for combustion, is sent to the catalyst 20 immerdiately and the intake port 8 is opened fully whereby flameless perfect combustion is effected.

IPC: H03K19/003
Filed: 1981-05-26
Abstract: PURPOSE:To find a fault of a device securely and easily by detecting whether the level of an input signal to an input terminal is a prescribed level or not. CONSTITUTION:A signal inputted to a termianl 1 is inputted to an internal logcal part 4 through the output line 2,000 of an input emitter follower 2. When the level (0) at the input terminal 1 is regareded as OV and the level (1) is regarded as -0.5V, the output line 2,000 of a current mode logic (CML) type logical circuit is at -0.8--1.3V as far as it is normal. Therefore, the basse-emitter voltage of the transistor 30 of a fault potential detecting circuit 3 provided to the output line 2,000 is <=0.25V and a detection output 3,000 is (0). If, however, a wire connected to the terminal 1 is broken, the potential of the output line 2,000 rises and consequently the transistor 30 turns on, so that the detection output 3,000 is (1).

Filed: 1983-05-06
Abstract: PURPOSE:To reproduce a sound output signal in variable speed reproduction without varying its frequency by selecting a reproducing output signal with a higher level between main and auxiliary rotary heads. CONSTITUTION:Outputs of sound main rotary heads M1 and M2 and sound auxiliary rotary heads S1 and S2 are amplified by head amplifiers 30-33 and inputted to switches 34 and 35. The switches 34 and 35 select outputs of a main and an auxiliary rotary head which scan on a magnetic head by head switching pulses inputted to an input terminal 39. For example, reproducing output signals of the M1 and M2 obtained at output terminals of switches 34 and 35 are inputted to a switch 36 while a comparison 37 between their levels is made. A comparator 37 operates the switch 36 and a reproducing output signal having a larger level between the M1 and S1 is selected and outputted to an output terminal 38. Consequently, the reproducing output signal having small output level variation is obtained. Further, the reproducing output signal is obtained during variable speed reproduction without varying the frequency of the sound output signal.
