Patent JP-S5641573-A (JP)
Title: Access system of memory circuit
Inventor: KOIKE HIDEJI
IPC: G11C11/413
Filed: 1979-09-06
Abstract: PURPOSE:To shorten an access time while setting sufficiently long times up to write and readout starts, by synchronizing the timing of the precharge start of an internal data bus with the rise of a latch control pulse signal. CONSTITUTION:To start the precharge of internal data bus IBUS simultaneously with the rise of latch control pulse signal ALE, time t3 is equalized to the time when the data signal of an address data bus is substituted with an address signal and the precharge when readout and write control signals RD and WR are active is made possible. Further, since time t3 is set sufficiently long, there is no need to set it long anew. Therefore, the access time can be shortened by the pulse width of precharge signal IBPC by setting sufficiently long the time from the precharge end of the internal data bus to the data write and readout starts.

Title: Magnetic recording/reproducing method
Inventor: SHIMODA KANEYASU
IPC: G11B5/02
Filed: 1992-05-07
Abstract: PURPOSE:To reproduce a magnetic recording medium without applying a bias magnetic field to an MR head in a magnetic recording/reproducing method for recording the medium by a thin film head and reproducing the medium by the MR head. CONSTITUTION:Binary data is recorded on a magnetic recording medium in a first step 11. One of the binary values is represented by a residual magnetization erase signal and the other is represented by a saturated magnetization signal. An intensity of the residual magnetization from the medium is detected by an MR head 35 in a second step 12. The detected intensity of the residual magnetization is decided by a binary value and reproduced as data in a third step 13. Further, in the first step, the residual magnetization of the medium is previously erased. In the second step, the record signal is formed of a signal which has an intensity responsive to data to be recorded and in which a direction of its magnetic field is inverted, and the data is recorded on the medium. Then, in the third step, at the time of reproducing, a magnitude of the magnetic field of the record signal of the medium is detected. In a fourth step, the magnitude of the magnetic field of the detected record signal is multi-level-judged and converted to a predetermined signal.

Title: Dynamic balancer circuit for transfer feeder
Inventor: NISHIDA KENJI
IPC: B30B13/00
Filed: 1992-05-07
Abstract: PURPOSE:To prolong the service life of a driving system by reducing the torque of the driving system of a transfer feeder.

IPC: B41J19/20
Filed: 1982-07-01
Abstract: PURPOSE:To prevent printing errors and quality degradation from occurring due to an irregularity in a linear scale, by providing a circuit means for correcting the DC level of a read signal to be constant when optically reading a linear scale. CONSTITUTION:Light emitted from a light-emitting diode 11 is received by a photo-transistor 31 through the linear scale 10 such as a steel scale provided with a slit pattern. The read signal (a) containing an increment or decrement is amplified by an amplifier 32 such as a differential amplifier. An output signal from the amplifier 32 is rectified and smoothed by a rectifying circuit 33, which sets a time constant for a C-R combination so as to leave only the increment or decrement (b) of the read signal (a). When the increment or decrement (b) is inputted to a page-side input terminal of the amplifier 32, an output (c) from the amplifier 32 is corrected so that the DC level becomes constant. The output (c) from the amplifier 32 is converted into a pulse by a comparator 34, which pulse is used as a printing timing pulse.

Title: Optical image arithmetic device
Inventor: TOMITA TADAO
IPC: G06E1/00
Filed: 1990-05-05
Abstract: PURPOSE:To perform logical operation and threshold value processing in a purely optical state by disposing a resonator provided with a PR crystal and a phase conjugation mirror and spatially modulating the threshold value of an oscillator over the PR crystal surface by radiating an input image on the PR crystal surface. CONSTITUTION:The characteristics of the PR crystal 1 such as non-reciprocity reflection and transmittivity which is generated by the energy combination in the PR crystal 1 between two luminous fluxes which are oppositely made incident to the PR crystal 1 is applied. That means, the resonator is made to be in an oscillating state by using the characteristics of non-resiprocity reflection and the transmittivity by two-wave combination of the light incident from an external part to the PR crystal 1 and the luminous flux which passes through the PR crystal 1 and is reflected on the phase conjugation mirror 2 in the PR crystal 1. At this time, by controlling the strength of the two-wave combination in the PR crystal 1 by the luminous flux which is independently made incident to the PR crystal 1 and provided with image information, the oscillating state is controlled and then the logical operation for the inputted image is performed. Then, the demand of high coherence of the inputted light in terms of time and the limit of the varying width of used wavelength can be restrained so that they may be minimized. Thus, it is difficult to be influenced by disturbance, and the logical operation for the inputted image can be satisfactorily performed even with the low intensity of light.

IPC: H04N9/455
Filed: 1990-05-02
Abstract: PURPOSE:To always apply an optimum burst gate pulse signal to a phase detection circuit and a killer detection circuit by extracting a burst signal in an optimum state through the forming of a burst gate pulse signal from a demodulation output of a burst signal and selecting the burst gate pulse signal to be applied depending on a level of an input signal.

The burst gate circuit 11 uses a demodulation signal of the input signal to generate a burst gate pulse. When an output of the killer detection circuit 4 checking a level of the burst signal in the input signal is in existence, the switch circuit 12 selects the burst gate signal generated from the burst gate circuit 11 so as to be fed to the phase detection circuit 2 and the killer detection circuit 4. Moreover, when no output exists in the killer detection circuit 4, the switch circuit 12 selects the burst gate signal from the delay circuit 5 so as to be fed to the phase detection circuit 2 and the killer detection circuit 4.
