Title: Fliudic gas meter
Inventor: NUKUI KAZUMITSU
IPC: G01F1/20
Filed: 1994-06-02
Abstract: PURPOSE:To measure the quantity of gas accurately with a pressure drop within an allowable limit regardless of fluctuation in the pressure on the inlet side of a gas meter. CONSTITUTION:The fluidic gas meter comprises a fluid oscillation element 14, a narrow channel 21 disposed on the upstream side therefrom, and a pressure fluctuation eliminating member 13 having a movable valve 23 and a valve seat 24 operable integrally with a diaphragm 22. Gas pressure P1 on the inlet side of a gas meter 11 acts on one side of the diaphragm 22 and the movable valve 23. The movable valve 23 is operated to decrease the open areas of the movable valve 23 and the valve seat 24 as the quantity of passing gas decreases using the pressure difference across the gas meter 11 produced depending on the quantity of passing gas. In a low flow rate range where the measurement accuracy is affected by fluctuation in the gas pressure PI on the inlet side, the gas is passed through the narrow channel 21 to attenuate the fluctuation width of the gas pressure P1 to a level having no effect on the measurement accuracy while sustaining the pressure drop below a level allowable for the gas meter.

Title: Electronic tuner
Inventor: FUJITA MASAHIRO
IPC: H03J7/02
Filed: 1979-09-21
Abstract: PURPOSE:To simplify the adjustment, by shifting the tuning frequency arbitrarily when slight shift of the tuning frequency is desired and enabling to use the fine adjusting switch even at the voltage tuning mode, in the electronic tuner used for TV receivers. CONSTITUTION:When a slight shift of the tuning frequency is desired during reception, with the adjusting switch 36 or 37 depressed toward desired direction, the signal from the coarse adjusting switch 35 is not input to the gate circuit 31, but the write-mode is automatically changed over. Further, to the selection gate circuit 23, the present data added or subtracted from the data in the presettable down counter circuit 33 is input. In this case, the circuit 31 controls the preset gate circuit 38, read/write change-over circuit 39, and generation circuit for changeover circuit 40 similarly the same as the case with the write-mode. Accordingly, the AFT signal is made off at the gate circuit 41. Thus, the fine tuning adjusting switch 36 can be used even at the voltage tuning mode, allowing to simplify the adjustment.

Title: Hydraulic pressure control valve used for braking mechanism of automobile
Inventor: KADOTA SHINKICHI
IPC: B60T8/26
Filed: 1980-09-03
Abstract: PURPOSE: To prevent decompression control by holding a plunger through the operation of a sliding member when one system is damaged.  
     CONSTITUTION: The sliding member 10 is subject to the hydraulic pressure of both systems, normally balances. When the hydraulic pressure of a front wheel system is not generated due to the damage of the front wheel system, the sliding member 10 receives leftward push force. When the sliding member 10 is left pushed, decompression control is not conducted because a pushing member 17 consisting of an elastic material generates force A tightening the plunger 5 and holds the plunger. Durability is improved because the pushing member 17 does not contact with the plunger 5 when normalcy.
