Patent JP-H04162105-A (JP)
Title: Programmable controller
Inventor: YAMAMOTO SATOSHI
IPC: G05B19/05
Filed: 1990-10-26
Abstract: PURPOSE:To prevent the malfunction of a programmable controller by reading out twice and continuously the A/D conversion data to use these data as the correct conversion data if the coincidence is secured between both data and then reading out the A/D conversion data in the 3rd time to obtain the correct conversion data if no coincidence is obtained between both data. CONSTITUTION:A CPU reads twice and continuously the conversion data out of a conversion data buffer 2 and compares these data with each other. If the coincidence is obtained between both data, the CPU decides no collision occurred between an output enable signal, the inverse of OE and a clock signal CK. Then these coincident data are stored in a memory area and used as the correct conversion data. If no coincidence is obtained between those two read conversion data, the CPU decides the collision between the signal, the inverse of OE and the signal CK. Thus both of these data are not used as the conversion value. Then the conversion data are newly read out and these read data are used as the correct conversion data.

Title: Read-only memory circuit
Inventor: HARADA AKIHIRO
IPC: G11C16/06
Filed: 1987-11-17
Abstract: PURPOSE:To increase a read speed and to improve a read margin by completely disconnecting a selected column line from a power supply means to set it to a certain potential like a ground potential. CONSTITUTION:One of each of pairs of memory cells 14-01-14-n4 which are connected to the same bit lines 11-1 and 11-2 and are selected by the same row line is selected by setting column lines 12-1-12-3 to a certain potential like the ground potential. Column lines 12-1-12-3 selected for read are disconnected from power supply means 90-1 and 90-2 because first switch means NMOSs 82-1-82-3 connected to them are turned off, and all of the other non- selected column lines 12-1-12-3 are pulled up by power supply means 90-1 and 90-2 because first switch means NMOSs 82-1-82-3 connected to them are turned on. Selected column lines 12-1-12-3 are completely pulled down to the certain potential like the ground potential in this manner. Thus, the read speed is increased and the read margin is improved.

Title: Optical scanner
Inventor: NAGATA MASAYA
IPC: G02F1/00
Filed: 1989-11-06
Abstract: PURPOSE:To make an accurate scan without any variation in the wavelength of laser light during the scanning by providing an external optical modulator which modulates the intensity of a laser beam between a semiconductor laser and an optical deflector. CONSTITUTION:The laser beam 30 after being transmitted through the external modulator 5 is made incident on the diffraction grating 23 of a hologram disk 21. The diffracting direction of the laser beam 30 changes according to the rotation of the hologram disk 21 and the diffracted light makes an accurate scan on a scanned surface 33. The external modulator 5 imposes the light intensity modulation upon the laser beam 30, so the light output of the laser beam 30 itself need not be modulated by controlling the quantity of a current applied to a semiconductor laser 1, so that the current inputted to the semiconductor laser 1 is held constant. Then the oscillation state and temperature of the semiconductor laser 1 are stabilized. Consequently, the wavelength variation of the laser beam 30 is suppressed and the accurate scan with high reliability can be made by using a diffracting element 23.

Title: Abnormality detecting device for rotary part
Inventor: CHITOKU MINORU
IPC: G01M13/04
Filed: 1991-11-06
Abstract: PURPOSE:To prevent an erroneous action in abnormality detection. CONSTITUTION:A dimensionless arithmetic unit 6 divides the amplitude of the AE signal at the center in the small time DELTAt by the average value of the amplitudes of the AE signals in the small time DELTAt. The friction AE signal having a longer duration than the small time DELTAt, smoothly changed with the amplitude, and having the amplitude change in the small time DELTAt smaller than that of the abnormality AE signal and nearly constant and uniform has the amplitude at the center of the time DELTAt nearly equal to the average value of the amplitude in the time DELTAt. All amplitudes of the friction AE signal are converted into nearly the dimensionless constant value 1, and the friction AE signal in the AE signal from an AE sensor can be removed. An erroneous action in abnormality detection caused by the friction AE signal can be prevented, and the abnormality of a rotary part can be correctly detected.

Title: Rectangular processing circuit
Inventor: ICHIHARA MASAKI
IPC: H03K12/00
Filed: 1987-11-16
Abstract: PURPOSE:To prevent chattering due to noise by providing a noninverting amplifier whose input terminal connects to other end of a resistive element and whose output terminal connects to an output terminal and a capacitive feedback circuit between the output and the input of the noninverting amplifier. CONSTITUTION:An input signal A impressed to an input terminal 1 is fed to an inverter 3 via a resistor 2 and an output signal C is obtained at an output terminal 6 via an inverter 4. The output signal C is fed to an input terminal of the inverter 3 via a capacitor 5. The moment the signal waveform at a point B crosses a threshold voltage of the inverter 3, the output signal C is inverted, resulting that a differentiation waveform of the output signal C is added to the potential at the point B for a prescribed time in response to the time constant depending on the capacitor 5 and the resistor 2. Thus, the output inversion for the time is inhibited and chattering due to noise is prevented.

Filed: 1988-11-18
Abstract: PURPOSE:To improve an S/N without deteriorating frequency characteristic for a signal by providing a means to detect the change of the illuminance of an object and a means to vary the enhancing characteristic of a non-linear high-pass enhancing circuit by a signal detecting the illuminance. CONSTITUTION:In the recording and reproducing device 2, a high-pass enhancing circuit 11 to enhance a high-pass area corresponding to the signal level of an input luminance signal is provided. Assuming an enhancing quantity in the case of inputting a small signal level as A, and the enhancing quantity in the case of inputting a large signal level as B, relation is set so as to be A>B. In photography with low illuminance, a signal level is amplified so as to obtain a specification level at en AGC circuit 5 since the signal level obtained from an image pickup element 4 is insufficient, however, simultaneously, amplification is also applied on a noise component included in the signal. A case such as low illuminance is detected at an illuminance detection circuit 7, and control so as to reduce enhancement on the noise component that is a small signal at the enhancing circuit 11 is applied by using the above detecting signal.

Title: Transfer recording method and transfer recording ink and transfer recorder for use in said method
Inventor: SATO MASA
IPC: B41M5/26
Filed: 1985-12-25
Abstract: PURPOSE:To reduce the quantity of optical energy required for the titled method and enable images to be transferred even where there is a time gap between forming of the images and transferring of the images, by a method wherein fine particles at a part irradiated with light are broken to generate heat, thereby melting a transfer recording ink at the part, and the melted ink is transferred onto a transfer recording material. CONSTITUTION:A transfer recording ink is constituted of fine particles 11 comprising water covered by a photo-breakable substance, fine particles 10 comprising sodium hydroxide covered by a photo-breakable substance, a pigment 12 and a supercoolable substance 13. When the ink is irradiated with light, the covering materials of the fine particles 10, 11 are broken, resulting in that water and sodium hydroxide mix with each other to generate heat, whereby the ink is heated to or above the melting point of the supercoolable substance 13. The supercoolable substance 13 at the heated part is melted, and is transferred onto a transfer recording material. Since the substance dominating the transfer characteristics in this transfer recording is the supercoolable substance 13, the transfer ink remain molten even when the temperature of the ink is lowered below the melting point of the supercoolable substance 13, so that the period of time during which transfer can be performed is long.
