Title: Rotary magnetic head device
Inventor: OGURA MITSURU
IPC: H01L41/09
Filed: 1983-06-10
Abstract: PURPOSE:To secure an ideal head touch state although a magnetic head receives the displacement in the axial core direction of a rotary drum, by reversing the voltage application direction to the electrodes at the side of an attachment part and the magnetic head in an area between the attachment part of a piezoelectric element to the rotary drum and the magnetic head. CONSTITUTION:The attachment side electrodes 18 and 18 and the magnetic head side electrodes 19 and 19 are formed on both sides of a piezoelectric substrate 15 of a piezoelectric element 13 in an area between an attachment part 16 to a rotary drum 12 and a magnetic head 14 with an insulation space 17 secured among those elements. These electrodes 18 on the upper side of the substrate 15 are connected to the electrodes 19 on the rear side of the substrate 15 by means of lead wires 20 respectively. Then the voltage application direction is reversed between electrodes 18 and 19, and therefore the bending can be set opposite to that due to the piezoelectric effects of the electrodes 19. As a result, the head 14 set at the tip of the element 13 can always be set rectangularly to a magnetic tape 11.

Title: Speed control device for speed governor in water turbine generator
Inventor: YAMAMOTO KOJI
IPC: F03B15/18
Filed: 1993-04-30
Abstract: PURPOSE:To improve reduction in speed after an excitation switch is closed even in a water turbine generator whose inertia is small by compensating an excitation loss after an excitation compensating signal is added to a speed preset value of the water turbine generator is when the generator is excited when it is started. CONSTITUTION:When a water turbine generator 3 is started, when a closing signal of an excitation switch is inputted to a single shot timer 12, a pulse signal having a constant time width is inputted to an AND circuit 13. This AND circuit 13 gives a bias signal by pulse width time to a subtracter 14 by input of the pulse signal. This subtracter 14 finds deviation between the bias signal and an output signal of an integrator 15 to integrate an output signal of the subtracter 14, and the output is given to an adder 16 as an excitation loss compensating signal attenuated by a preset time constant, and is added to a speed preset value set by a speed setting unit 1. Opening of a guide vane of a water turbine is adjusted according to a compensated signal. Thereby, influence of an excitation loss can be avoided, and time until the generator reaches rated speed can be shortened.

Title: Solid-state image pickup device
Inventor: TAKESHITA MITSUAKI
IPC: H04N5/335
Filed: 1981-07-06
Abstract: PURPOSE:To perform efficient image pickup operation by providing an electrode which capacity couples with a photodetector and making the bias voltage of this electrode in a photodetection period different from bias voltage in a signal charge readout period. CONSTITUTION:A transfer electrode 13 is supplied with a binary-level clock which contains a vertical transfer clock. Then, an overflow control electrode 21 is applied with a bias voltage which has two levels, namely, having a high level during photodetection and at a low level during the reading of signal charge. In this case, the bias voltage of the electrode 21 drops during the reading of signal carge, so the potential of an element part 1 capacity-coupled with the electrode 21 also drops. Therefore, the level of the bias voltage applied to the electrode 21 is selected adequately to read the signal charge out of the element part 1 to a transfer part 2 through a gate part 6.

IPC: C02F1/04
Filed: 1981-07-08
Abstract: PURPOSE:To dry a muddy arsenic-containing substance efficiently, by irradiating the substance with microwaves in an irradiation amount sufficient to evaporate the water contained in the substance but insufficient to change the form of arsenic or evaporate arsenic. CONSTITUTION:The muddy arsenic-containing substance such as arsenic oxide or arsenic sulfide obtained by treating arsenic-containing fume ash, slime, waste liquid or the like is subjected to dehydration filtration to obtain a dehydrated cake.

Title: Write signal generating circuit
Inventor: OOISHI TSURATOKI
IPC: G11C11/403
Filed: 1983-06-15
Abstract: PURPOSE:To form an internal write signal even if a write enable signal is fixed to a low level by providing a detection circuit of an address signal in the inside of a memory and detecting the change in an address signal to generate automatical a proper signal. CONSTITUTION:An address change detecting circuit 9 outputs a detecting signal phiD when address signals Ax, Ay are changed. The signal phiD is applied to a signal forming circuit and an address clock signal phiATD having a proper pulse width is outputted. The signal phiATD is inverted and applied to an AND gate circuit 12 to which an internal write control signal phiWE outputted from a buffer 6 is inputted. In case of write, since the control signal phiWE is brought into a high level, a high level internal write signal phiWE2 is formed only during the low period of the signal phiATD by the input of the inverting signal of the signal phiATD and a write circuit 7 conducts data write during this period. Thus, the internal write signal is formed automatically by setting properly the falling of the signal phiATD at the point of time of change in the address signal.
