Title: Manufacture of pasted electrode plate for lead storage battery
Inventor: HOSHIHARA NAOTO
IPC: H01M4/20
Filed: 1981-12-16
Abstract: PURPOSE:To enhance the cycle life of a pasted electrode plate for a lead battery by suppressing the reduction of the initial characteristic of the electrode plate by pressing the lower part of the electrode plate while absorbing water from said lower part  after the electrode plate is prepared by applying a lead paste to a grid, and solidifying  thus treated electrode plate by drying. CONSTITUTION:A usual lead paste or a relatively-low-density paste 2 which satisfies a  rapid-discharge characteristic, is applied to an expanded grid 1 made of a Pb-Ca system  alloy to make an electrode plate. Next, the lower part of the electrode plate is pressed  to around 3/4 of its thickness while absorbing water from the lower part so as to form  a pressed part 3. After that, thus treated electrode plate is dried and solidified to  make a pasted electrode plate. Therefore, in this electrode plate, the grid 1 and the  active material 2 are made to firmly bound to one another. Besides, since an increased  amount of electrolyte is contained in the lower part of the electrode plate due to its  decreased thickness, the softening or separation of the active material 2 can be suppressed by moderating increase of the concentration of the electrolyte. Consequently,  the life characteristic of the electrode plate can be enhanced by preventing any deterioration of its rapid-discharge characteristic.

Abstract: PURPOSE:To obtain video detection signal with less phase jitter in terms of a television receiver by detecting the frequency difference between the carrier frequency of a video intermediate frequency signal and the oscillation frequency of a voltage control oscillator in a phase synchronizing loop and using the detected signal for adjusting frequency.

Title: Pressure reducing valve
Inventor: MAEDA KATSUHIRO
IPC: G05D16/10
Filed: 1983-11-01
Abstract: PURPOSE:To stop pressure reducing operation when entrance side pressure exceeds a set value, and hold exit side pressure as high as the entrance side pressure by providing an intake valve which opens a back pressure intake passage when the pressure in an inflow passage exceeds the set value to the back pressure intake valve. CONSTITUTION:When pressure higher than the set value set with a compression spring 31 for releasing is applied to the inflow passage 14 of a pressure reducing valve 10, an intake piston 30 is pressed down and the back pressure intake valve 37 leaves a back pressure intake valve seat. Consequently, the pressure in the inflow passage 14 is guided to the back pressure chamber 27 behind the differential piston 13 to rough a valve chamber 19, valve seat 36, intake cylinder chamber 28, and passage 29. Consequently, the area ratio to pressure operating on the differential piston 13 vertically becomes almost 1:1 and both pressures Pi and Po are balanced on the basis of the area ratio. Therefore, pressure reducing operation is stopped and the pressure Po in an outflow passage 15 rises as the pressure Pi in the inflow passage 14 rises.

Title: Calorimeter
Inventor: NUKUI KAZUMITSU
IPC: G01K17/10
Filed: 1990-08-02
Abstract: PURPOSE:To measure a heat value of a fuel mixed gas handily as a function of a loss pressure by connecting a thermal type flowmeter in series to a laminar flowmeter to detect a pressure loss at a reference state of the laminar flowmeter. CONSTITUTION:Fuel gas of a specified pressure is kept at a temperature T of a heat insulating cell 12 before it flows into a laminar flowmeter 5. An inflow pressure P1 of the flowmeter 5 is detected in an absolute pressure and an outflow pressure P2 is calculated from measured values of the pressure P1 and a differential pressure DELTAP. A capacity flow rate of the fuel gas currently passing through the flowmeter 5 represents a flow rate at a reference state depending on an inflow temperature T, an absolute inflow pressure P1, an outflow absolute pressure P2, the differential pressure DELTAP and the like and a mass flow rate of the fuel gas to be measured with a thermal type flow controller 8 corresponds to the capacity flow rate exactly. Moreover, a heat value H of the fuel gas can be shown on a heat value display device 10a as such proportional to the inverse of the differential pressure DELTAP of the flowmeter 5 from pressures P1 and P2. Thus, a heat value of a mixed fuel gas can be measured at a high accuracy by a simple means.

Title: Output buffer circuit
Inventor: FUJIWARA TSUKASA
IPC: H03K17/687
Filed: 1988-08-18
Abstract: PURPOSE:To cause a slit in an input signal of an output circuit and to eliminate a through-current with the less number of components by selecting the beta of an N-channel transistor(TR) more than the beta of a P-channel TR. CONSTITUTION:The circuit consists of N-channel TRs 6a, 6b having the 1st beta, P-channel TRs 5a, 5b having the 2nd beta, a P-channel TR 5c and an N-channel TR 6c, and the ratio of beta is selected as 1st beta/2nd beta>5. When an input signal V1 rises at a time t1, since the beta of the TR 5a is small, the signal VA rises gradually by a time constant. Since the beta of the TR 6b is large, the signal VB descends at a time t1 and an output signal VC of an inverter 4b rises at the same time. Then when the potential of the signal VA exceeds a threshold voltage of the TR 6c, an inverted signal V0 is outputted from an output terminal 8 at a time t2. That is, a slit is caused in the input signal of the output circuit between the times t1 and t2 to form the state that both the TRs 5c, 6c are turned off thereby eliminating a through-current.
