Title: Package structure of magnetic bubble module
Inventor: MASUMOTO YOSHINARI
IPC: G11C11/14
Filed: 1983-03-03
Abstract: PURPOSE:To reduce external magnetic fields produced by plate type permanent magnet incorporated in bubble modules without increasing weight nor price by arranging magnetic bubble units in the opposite directions alternately and cancelling module external magnetic fields by each other. CONSTITUTION:The direction 6' of the magnetic field produced by the plate type permanent magnet of the magnetic field correction type magnetic bubble module is the same as the direction of fitting legs 4, namely, opposite to that of a general module and of almost the same size. Those modules are packaged so that their magnetic fields face up and down alternately. Consequently, external magnetic fields generated by plate type permanent magnets cancel each other on the board wherein plural bubble modules are packaged. Therefore, when corrections are made to approximate the composite magnetic field outside of the bubble modules to zero, the need for a special magnet for the correction and a shield case is eliminated, so the weight, shape, and price are reduced.

Title: Flow rate control valve
Inventor: KIDOUCHI YASUO
IPC: F16K31/40
Filed: 1990-02-15
Abstract: PURPOSE:To proportionally regulate a flow rate according to the magnitude of the current value to a solenoid by interlocking a control valve and a pilot valve with a plunger driven by the solenoid, and causing a pressure difference between a first pressure receiving body and a first back pressure chamber to generate a flow to the control valve. CONSTITUTION:When a current is sent to a solenoid 26, a plunger 27 is attracted against a second spring 21 energizing a control valve body 17, and a pilot valve 28 provided on the top of a shaft 25 connected thereto opens a pilot hole 24. Therefore, the pressure of a first back pressure chamber 11 is lowered, a diaphragm 10 is separated from a first valve seat 13, and a fluid is sent to a control valve 16. When the current value is small, the opening part formed by the control valve body 17 and a second valve seat 18 is small and the discharge quantity of the fluid is less. When the current value is increased, the control valve body 17 is further lifted to increase the discharge quantity of the fluid, so that the flow rate of the fluid can be regulated by the adjustment of the current value.

Patent JP-S63204186-A (JP)
Title: Digital rate meter
Inventor: YODA MASAKI
IPC: G01T1/17
Filed: 1987-02-20
Abstract: PURPOSE:To keep a standard deviation within an allowable range, by a method wherein the computation of a counting rate is performed to give standard deviation a first value while the computation of a counting rate is done to bring standard deviation to a second value larger than the first value to determine whether the difference between the values exceeds a specified error range or not. CONSTITUTION:An arithmetic processor 15 reads counts at each unit time stored in a memory 21 sequentially as required. Counting rates N1AV and N2AV and errors sigma1 and sigma2 are calculated by these computations. A discriminator 16 employs the counting rate N1AV to be outputted on an output display device 22. When exceeding the counting rate N1AV, the counting rate N2AV is employed to be outputted on the output display device 22. Here, the employment of the counting rate N2AV indicates that a sharp change occurs. In this case, the first computation following the subsequent operation is performed in such a manner that the start of computing of counts in the first computation does not precedes the last of the second computation in conveniences sake. Only this step enables quick processing of data.
