IPC: C25B3/25
Filed: 1980-03-31
Abstract: PURPOSE: A titanium nitride electrode for electrolytic reduction which comprises coating the surface of a base material with titanium nitride and which is high in hydrogen generating voltage, has no fear for the occurrence of public hazards such as environmental pollution and exhibits superior current efficiency.  
     CONSTITUTION: This titanium nitride electrode is manufactured by, for example, the following method. Namely, a base body (e.g.; metal Ti molding) is calcined for more than one hour at 900W1,600°C in N 2  or NH 3  or in a mixed gaseous atmosphere adding further H 2  to this, whereby a film of titanium nitride is formed over the entire surface of the base body. As a result, the intended titanium nitride electrode for electrolytic reduction formed with the film of titanium nitride of uniform and dense cubic crystals over the entire surface of the base body is obtained. The purity of metal Ti as the base body is preferably as high as possible, and in general, ≥95% is preferable.

Title: Pressure controller
Inventor: SHOJI HIROSHI
IPC: B23K26/14
Filed: 1992-01-31
Abstract: PURPOSE:To expand the pressure control range and to decrease the cost by performing the accurate pressure control in the low pressure area by reducing the hysteresis width of the discharging pressure in the outstanding section area adjustment mechanism. CONSTITUTION:A pressure control valve 1 make the pressure value of the fluid to be controlled from a sensor 1a match to the set pressure value. The orifice diameter of an orifice 4 can be changed by a changeover valve 3. In the high pressure area of the pressure, a hand-operated changeover valve 3 is fully open. In the low pressure area, the valve 3 is closed and a flow path with the high conduit resistance by the orifice 4 is used to discharging air from a nozzle 5. The pressure loss by the orifice 4 makes the discharge pressure lower than the control pressure. Thus, the hysteresis width of the discharging pressure is decreased, enabling the accurate pressure control in the low pressure area. In short, the conduit resistance from the valve 1 to the nozzle 5 can vary, resulting in reducing an error due to the hysteresis width.

Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a flow rack capable of performing a product supplementing operation and a product picking operation from the same front side of a rack while maintaining a first-in first-out function. SOLUTION: A flow rack device is structured so that, when supplement of products is required to either of right and left storing slide members 4, a supplement direction switchover member 8 is rotated to a storage slide member side by a handle 9 and the required number of products 10 is input from an input port onto an input slide member 6. By this, the input products lower through the input side member 6, fall on the rear side of the storage slide member located under a supplement direction switchover member by the supplement direction switchover member inclined to the supplement side, further lower through the storage slide member toward the forward picking operation side, arrive at the rearmost of a group of products stocked on it, and stop there.  Thus, while maintaining a first-in and first-out function, product supplement operation can be performed on the same side as for picking operation.

Title: Power supply circuit
Inventor: ASAI SHUNJI
IPC: H04N5/63
Filed: 1989-02-20
Abstract: PURPOSE:To prevent a ripple voltage from being generated and to prevent distortion from being generated in a vertical direction on a picture by directly detecting an output voltage without passing through a coil or capacitor, etc. CONSTITUTION:When the horizontal frequency of a received signal is high, a reference voltage Vh to be generated from reference voltage generation circuits 8 and 81 becomes higher in correspondence to this high horizontal frequency, and an adjusting voltage Vc to be outputted from a voltage conversion circuit 82 becomes lower. Reversely, when the horizontal frequency is low, the voltage Vc is increased. As a result, when an error between the voltage Vc and a target output voltage becomes larger, a control circuit 6 controls a switching circuit 3 based on the output of an error detection circuit 7 so that an output voltage Eb becomes lower when the horizontal frequency is low and that a voltage Eb is increased reversely when the horizontal frequency is high. When the horizontal frequency is fixed and the error is generated by load fluctuation between the voltage Eb and target output voltage, the circuit 6 controls the circuit 3 so that the voltage Eb can be maintained to the value of the target output voltage.

The outputs of circuit 3 are mixed by resistances R3 and R4 by adding and the sum is negatively fed back to the output line of circuit 1 via DC negative feedback circuit 4. Circuit 4, consisting of operational amplifier OP2 and the integrating circuit of capacitors C1 and C2, controls switch SW by the control signal of channel selection detecting circuit 5 in channel selection to decrease the integral time constant. Consequently, the DC potential variation of the demodulation output is suppressed and DC variation in channel selection can directly be coupled without being transmitted to the audio amplifier stage.
