Title: Semiconductor memory device
Inventor: YASUDA HIROSHI
IPC: G11C11/34
Filed: 1984-05-14
Abstract: PURPOSE:To make the allowance with respect to noises larger and to speed up actions by providing a reference potential generator circuit on a data detection circuit and producing a voltage in accordance with a memory element with respect to the reference potential through a current/voltage converting element. CONSTITUTION:After an output terminal 11 of a row line 12 is made to a grounding potential by transistors 13 and 19 for switching on and off sequentially, it is made into a high potential. Then a row selection transistor 2 is turned on, while a transistor 3 of an ROM memory element is also turned on in accordance with the storage content when a threshold is small. A current flows through a resistance 7 of a current/voltage converting element from a reference potential generator circuit 18 of a detection circuit, and a lower storage contents with respect to the reference potential is detected as a voltage irrespective of a power supply voltage, etc. On the other hand, when the threshold of the storage contents is larger, the transistor 3 is turned off, and the storage contents are detected as a high voltage with respect to the reference potential on the basis of a current for flowing in the circuit 18. As a result, even if a resistance value of the resistance 1 is set larger, a action speed will not drop, and a high speed action can be possible with a larger allowance degree against noises caused by the fluctuation of the power source.

Filed: 1992-04-16
Abstract: PURPOSE:To provide an indicator with safety which is higher than that when an image projected on a screen by a slide projector, etc., is irradiated with a laser beam so as to locally make a highlight. CONSTITUTION:Only when the laser out-going side end face of the indicator 1 turns upward from a horizontal surface at a prescribed angle, for example, an inclination sensor 6 detects it so that a control circuit 7 permits the out-going of the laser beam 4 from a semiconductor laser diode 3. Therefore, the laser beam is not emitted even if the indicator held by a lecturer on a rostrum happens to turn to audience sitting in a lower position, for example, so that it is safe.

Filed: 1988-04-19
Abstract: PURPOSE:To reduce the size of the directional coupler by reducing the width of the base of a sepn. zone, thereby forming two waveguides to the small distance therebetween. CONSTITUTION:A dielectric material is selectively grown by liquid epitaxy on a substrate 1 to form the sepn. zone 3 and thereafter, a 1st mask is removed and a 2nd mask 4 covering a 1st waveguide forming region 51 and the 2nd waveguide forming region 52 on the substrate on the sepn. zone and the substrate on both sides of the substrate are formed. A clad layer 6 is formed with the 2nd mask as a mask. The width and height of the base of the sepn. zone 3 can be controlled by changing the liquid phase epitaxial growth conditions. The spacing between the 1st waveguide forming region 51 and the 2nd waveguide forming region 52 on both sides of the sepn. zone can be thereby reduced and the spacing between the 1st waveguide 71 and the 2nd waveguide 72 is reduced.

Title: Controlling method for pump
Inventor: USUDA ISAO
IPC: H02P7/06
Filed: 1987-04-20
Abstract: PURPOSE:To enhance the performance of a pump by controlling a voltage applied to a pump motor in response to a value obtained by subtracting a voltage proportional to a current flowing to the motor from a set voltage. CONSTITUTION:A set voltage Er is input to the noninverting input terminal 11 of an operational amplifier 6 of a subtractor 9, and a voltage across a current detecting resistor 5, i.e., a detection voltage E1 proportional to a pump motor current is input from a connecting point 7 to an inverting input terminal 10. A voltage controller 3 to which an output voltage EV is input from the amplifier 6 outputs a motor voltage VM to a pump motor 4. Thus, high lift is obtained in a low flow rate range, and a controlling method for the pump which can be used in a high flow rate range can be obtained.

Title: Operating device for switch
Inventor: NISHIDA ISAO
IPC: H01H33/40
Filed: 1988-04-21
Abstract: PURPOSE:To prevent failure in operation of a movable contactor due to such causes as scuffing at a link by giving a stop signal to a motor for energizing a spring after detecting the termination of operation of the movable contactor. CONSTITUTION:When a gear member 2 is driven with a motor 1, the force is transmitted to a spring lever 3 to energize the spring, which, when it is moved beyond a preset position, release its energy to rotate a driving lever 4 rapidly, thereby closing through a link mechanism 13 a movable contactor. If the movable contactor stops midway due to scuffing on the link mechanism 13, etc., a detecting device 6a sends no output because the driving lever 4 can not reach the terminal edge, and the motor 1 does not stop. The gear member 2 is further rotated counterclockwise, and the joint 2d of the member 2 is apposed to the joint 3a of the spring lever 3 to rotate the apposed and jointed driving lever 4 in the same direction as that of the spring lever 3. Further, the movable contactor 14 is operated through the link mechanism 13, and the driving lever 4 reaches the terminal edge so that the detecting device 6a detects it and the motor 1 stops. This contrivance can be surely operated while working as a spring-operated device, as a motor-driven device in case of accidents.

Title: Malfunction preventing circuit
Inventor: SAKAMAKI TSUTOMU
IPC: G05B9/03
Filed: 1986-04-28
Abstract: PURPOSE:To prevent the influence caused by a malfunction of another package set on the same bus by increasing forcibly the output signal of a working system up to a level close to the power supply voltage as long as the malfunction of a stand-by system may possibly give an adverse influence to the working system. CONSTITUTION:At the time of a normal operation, a circuit set at the side of a CPU 100 is used and the LOCK signals of both CPU 100 and 200 are kept at low levels. The STB signal of the CPU 200 is set at a low level. Then the LOCK signal of the CPU 200 is set at a high level in case the CPU 100 is defective and replaced. Thus a transistor 203 is turned on and the STB signal is raised up to a level VCC. Therefore the level VCC is kept on a bus even in case the STB signal output is set at a low level while the CPU 100 is replaced. Thus the receiver side is never affected.
