Title: Silver brazing method
Inventor: YAMAMOTO JIROU
IPC: B23K1/20
Filed: 1979-01-31
Abstract: PURPOSE: To suppress alloying of Ni and silver braze and reduce the rate of leak occurrence by interposing minute protrusions in the portions to be brazed in silver brazing in which Ni exists in the portions to be brazed.  
     CONSTITUTION: In order to prevent the decrease in mechanical strength and the occurrence of leakage by controlling the thickness of braze material, it is effective to maintain the thickness of braze layer by interposing metal pieces 8 of, e.g., about 0.04W0.1mm, to the portions to be brazed in brazing plane surfaces to themselves, particularly horizontal plane surfaces to themselves of the assembled part 7 of the structure in which the part sinks in the perpendicular direction. Because of this, Ag-Cu eutectic alloy remains sufficiently in the brazing layer 9, and the rate of leakage occurrence is made nearly nil.

Title: Key input device
Inventor: KOMAKI SHIGEKI
IPC: G06F3/02
Filed: 1983-01-24
Abstract: PURPOSE:To reduce the load of key operation by forming slits at both sides of a key electrode and providing the pressure-sensitive conduction rubber under the electrode. CONSTITUTION:When a key symbol of a decorative panel 1 is pushed, a comb- tooth electrode of the corresponding flexible substrate 2 moves down to compress the pressure-sensitive conduction rubber 3 provided right under the electrode. Thus the rubber 3 conducts electrically, and the short-circuit is applied between the comb-tooth electrodes to obtain a key input signal. The key operation load is decided just by the flexibility of both panel 1 and substrate 2. The slits 2-2 are formed at both sides of a comb-tooth electrode 2-1 to facilitate bending of the substrate 2. This device further reduces the key operation load.

Title: Measurement of engine suction pressure
Inventor: NANBA SHINJI
IPC: G01L23/24
Filed: 1981-01-27
Abstract: PURPOSE:To always achieve accurate measurement of an average suction pressure by determining an average value of pressure signals sampled at the following two points: a certain angle position of rotation of a crank shaft and that after a half cycle from the preceding angle position. CONSTITUTION:An arithmetic circuit 4 receives a signal 403 at each half cycle T/2 of a sucking pulsation from a crank shaft angle of rotation detector 3 to sample a signal 402 of a pressure converter 2 located between a choke valve and a cylinder inlet. At this point, if there is no suction pressure stored in a memory device, the signal 404 thus sampled is stored as suction pressure a. When the subsequent signal is sampled after T/2 from the position, an average is calculated between the suction pressure signal b thus sampled and the suction pressure signal a stored in the memory device while the pressure signal b is memorized into the device as pressure signal a and the average pressure is output from 408. This operation is repeated at intervals of half cycle T/2. This measuring method enables invariably accurate measurement without effect and delay in the response due to the size of the sucking pulsation and deviation in the phase.

IPC: H02M7/10
Filed: 1980-01-31
Abstract: PURPOSE:To obtain the rectified voltage of 2<1/2>/n times the AC power source voltage by charging pieces of capacitors at every half cycle of the AC power source voltage, connecting these capacitors to a load in parallel, and discharging these capacitors. CONSTITUTION:A current is supplied to a diode Db, the capacitors C1-Cn and diode D1-Dn-1 when a terminal 1a is in the positive half cycle. Since the capacity of the capacitor C1-Cn is the same, the capacitors are charged to the approximately equal voltage. The rectified voltage which is the 2<1/2>/n times the AC power source voltage is applied to the load R0. When a terminal 1b is in a positive half cycle, a transistor Tr is conducted through a diode Dc and a resistor R1. The electric charge of the capacitor C1 is discharged through the transistor Tr and the electric charges of the capacitors C2-Cn-1 are discharged through diode D''1-D''n-2, the transistor Tr, the load R0, and diodes D'1-Dn-1. Since the capacitors C1-Cn are virtually connected in paralll with the load R0, the rectified voltage which is 2<1/2>/n times the AC power source voltage is likewise obtained.
