Title: Information recording and reproducing device
Inventor: KANEBA YUTAKA
IPC: G11B5/02
Filed: 1988-06-27
Abstract: PURPOSE:To reduce the disturbance caused by a frequency which appears on a reproducing screen and to improve the quality of a reproducing image by controlling a level of power supplied to an amplifier from a power source use oscillator so that it becomes lower than that in other period, when an image appears on the reproducing screen. CONSTITUTION:A reproducing voltage which passes through an amplifier and a rotary transformer from a video head and applied to a signal processing circuit 4 is demodulated, and a reproducing luminance signal is outputted to an output terminal 14. This reproducing luminance signal is inputted to a synchronizing separator circuit 15, as well, and a horizontal synchronizing signal (b) is inputted to a gate circuit 17 of a power source use oscillator OSC 5. The gate circuit 17 gates an output of high frequency power (c) from an oscillator 16, whenever the horizontal synchronizing signal (b) is inputted. In such a way, the output is provided to the rotary transformer from the OSC 5 only in a synchronizing signal period, therefore, in a recording and reproducing period for information, a level of power supplied to the amplifier can be made lower than that in a blanking period accompanied with a synchronizing signal, and the disturbance caused by a frequency on a reproducing screen can be reduced.

Furthermore, each target liquid pressure value to a wheel cylinder 4 of each rear wheel is calculated to control liquid pressure of the wheel cylinder 4 of each rear wheel by comparing the value with each liquid pressure which acts actually. It is possible to bring actual brake force to the target brake force by repeating this control in a short cycle.  Consequently, it is possible to apply brake on the car body in a good condition by making proper brake force act on each rear wheel securely in accordance with the weight of the car body and improve stability of the car body greatly when brake is applied on the car body.

Filed: 1990-06-19
Abstract: PURPOSE:To prevent plural cylinders from being continuously unburnt to relax shocks by stopping the fuel supply for each cylinder-group by 720 deg. crank angle at the different timings of period or phase. CONSTITUTION:Respective cylinders 28, 30, 32, 34 of an engine 2 are grouped into a first cylinder-group IJ1 into which fuel is injected from injectors 46, 48, and a second cylinder-group IJ2 into which fuel is injected from injectors 50, 52. When the car speed detected by a car speed sensor 66 exceeds a stop- starting car speed, ECU54 stops the fuel supply of a part of the cylinder groups IJ1, IJ2 to forcedly control the car speed below the stop-starting car speed. At this time, the fuel supply is stopped for the cylinder-groups IJ1, IJ2 every 720 crank angle at the different timings of period or phase. Thus, since plural cylinders can be prevented from being continuously unburnt, fluctuations in output of the engine due to stopping of the fuel supply can be reduced.

IPC: H01L21/8242
Filed: 1990-06-19
Abstract: PURPOSE:To remove a device with adverse reliability by parallelly providing P channel and N channel transistors at the equalize transistors of both bit lines and applying the inverted signal of a memory cell plate impressing voltage, which is inputted from the outside, as a bit line voltage. CONSTITUTION:First of all, Tr Q3 and Q4 are added as bit line equalize MOS transistors. This is for impressing stress to a bit line BL or for turning to Ov or Vcc. When N channel Tr Q1 and Q2 are turned ON< equalization to the Ov is enabled. When equalizing to the Vcc level, however, the P channel Tr Q3 and Q4 play the role. Thus, on standby for a wafer test, by setting a Vcp5 at Ov or the Vcc, the potential difference of the Vcc is applied between a CP and a BL, and a stress test can be executed. Even in a forwarding test, by providing an introducing means composed of a super Vcc or the like, the stress test similar to the wafer test can be executed, and a memory integrated circuit can be realized with high reliability.

Filed: 1987-06-29
Abstract: PURPOSE:To contrive to improve the transmission characteristic by adjusting the input level optimum to a MODEM signal automatically in a high efficient voice OCDEC enabling the transmission of MODEM signal. CONSTITUTION:A digital signal is converted into a MODEM signal comprising an analog signal via a MODEM and given to a PCM coder 1. The PCM coder 1 converts the analog signal into a digital signal. The signal is amplified or attenuated by an AGC amplifier 2. In this case, a MODEM signal detection section 7 detects that the input digital signal is the MODEM signal to output a detection signal. In receiving the signal, a signal power calculation section 8 in the AGC amplifier 2 calculates the power of the digital signal in the output of the amplifier/attenuator 9 and outputs the control signal based on the result of calculation to the amplifier/attenuator 9. The amplifier/attenuator 9 amplifies or attenuates the input signal in response to the control signal to apply feedback control thereby keeping the power level of the output digital signal of the AGC amplifier 2 to a prescribed level at all times.
