Title: Dynamic semiconductor memory
Inventor: HATAKEYAMA ATSUSHI
IPC: G11C11/407
Filed: 1995-04-26
Abstract: PURPOSE: To prevent the destruction of data in a memory cell by inserting an element between line A for feeding the negative voltage of word line W and a line B for feeding the bias voltage of an FET in order to prevent the charges, discharged to the line A, from flowing into the line B when the voltage on the line W makes a transition from positive to negative. CONSTITUTION: A switch element, i.e., an nMOS transistor(Tr) 56, is connected between the lines 52, 55 for feeding the output from active and stand-by negative voltage generators 50, 53. When the access is ended during active period and a word line WL0 drops from a word line boost voltage SVCC down to the ground voltage, charges are discharged from the line WL0 to the line 52 through Tr 49, 48. Consequently, a Tr 56 is disabled by a control signal ϕ to block the charges flowing into the line 55 thus preventing the back bias voltage of cells Tr1300 -Tr13nm from fluctuating due to the charges. With such circuitry, data in memory cells 1100 -11nm can be protected against destruction without increasing the chip area or current consumption at the time of stand-by.

Title: Tracking controller
Inventor: INADA HIROSHI
IPC: G11B7/09
Filed: 1982-06-14
Abstract: PURPOSE:To position an optical spot to the center of a tracking guide groove, by adding a voltage proportional to the reflected amount of light from a recording medium to a tracking control system of the optical spot, and eliminating an offset of the tracking control system. CONSTITUTION:Outputs of two light sensors are added at an addition amplifier 30 and amplified to a value corresponding to a tracking offset. An output of a differential amplifier 31 being a tracking error signal and an output of the adder 30 corresponding to the tracking offset are added or subtracted at an operational amplifier 32, the tracking offset included in the tracking error signal is eliminated and the tracking error signal without any offset is outputted. This tracking error signal drives a tracking actuator 25 coupled with a condenser lens 24 via a filter amplifier 33 and a power amplifier 34 toward the direction of tracking and positions the optical spot 27 to the center of the tracking guide groove.

Title: Production of grain boundary layer type ceramics
IPC: H01G4/12
Filed: 1992-03-27
Abstract: PURPOSE:To obtain a circular grain boundary layer type ceramic with a low rate of change in electrostatic capacity with a temperature change and a small dispersion thereof by coating only the inner peripheral surface of a cylindrical semiconductor porcelain with a grain boundary layer-forming agent and then thermally diffusing the grain boundary layer-forming agent in the grain boundary. CONSTITUTION:A cylindrical semiconductor porcelain is prepared and only the inner peripheral surface of the semiconductor porcelain is then coated with a grain boundary layer-forming agent (an insulating agent). The grain boundary- forming agent is subsequently diffused into the grain boundary of the semiconductor porcelain to afford the objective ceramics. In the process for thermally diffusing the insulating agent, since only the inner peripheral surface of the semiconductor porcelain is coated with the insulating agent, vaporization of the insulating agent and outflow thereof to a setter hardly occur and the dispersion in diffusion is extremely reduced. Thereby, the insulating layer is stably formed in the grain boundary even in a state of a low diffusion temperature and the O2 diffusion advanced not so much.

Title: Power source and driving circuit for computer
Inventor: KIUCHI MASAYOSHI
IPC: G06F1/00
Filed: 1987-04-25
Abstract: PURPOSE:To decrease the power consumption by actuating a clock oscillating circuit of a high frequency only in a fast processing state. CONSTITUTION:When a presetting state of a resetting circuit 8 is released, a crystal oscillator 22 is actuated. Thus the circuit 8 counts the prescribed number of pulses of the oscillator 22 and sets the output of the oscillator 22 at L. Thus the resetting state of a clock selecting circuit 7 is released and a clock signal of a low frequency is sent to a CPU 9 from a NAND gate 5 as a system clock. Simultaneously, a clock signal of an L level is also applied to a reset input R of the CPU 9. Thus the CPU 9 is ready to start and a computer is actuated by a system clock of a low frequency. In a fast processing state a crystal oscillator 23 starts its oscillation for output of a signal of a high frequency. Then the oscillator 23 is driven again at a low frequency when a fast processing action is over.

This unit 25 cuts out the power frequency band via a filter internally provided therein to thereby produce only the pulsating voltage, increases its frequency upon acceleration of the rotor 11 at starting time, close the switching relay 24 when it reaches predetermined frequency, and shorts both ends of reactors 21a∼21c to thus switch the motor 1 to full voltage operation. Thus, it can smoothly and simply switch the motor to its full voltage operation.
