IPC: H03F3/45
Filed: 1988-03-29
Abstract: PURPOSE:To increase the input dynamic range of constituting a current mirror circuit receiving an output from a differential circuit by pnp and npn transistors(TR) and a reference voltage setting circuit. CONSTITUTION:The reference voltage setting circuits 20a, 20b are inserted in a feedback loop consisting of pnp TRs 3a, 3b, 16a, 16b and npn TRs 4a, 4b, 14a, 14b, 15a, 15b in the current mirror circuit. Thus, it is possible to decrease the collector potential of the npn TRs 4a, 4b 14a, 14b, 15a, 15b more than the base potential and the collector-emitter voltage Vce is made constant. Thus, even if an input signal is lowered up to a voltage of a negative power line 7, the pnp TRs 3a, 3b, 16a, 16b forming a differential circuit are not saturated and a signal is outputted from an output circuit. Thus, the differential amplifier whose input dynamic range is wide and whose offset is small is obtained.

IPC: G01N21/88
Filed: 1985-04-12
Abstract: PURPOSE:To easily detect a defect in the pattern of a substrate by superposing a mask which has a light reflecting part at a part corresponding to the light shied part of the substrate and a light transmission part at the remaining part and irradiating the substrate from its reverse surface. CONSTITUTION:The pattern which has the light shield part 16 is formed on the light transmissive substrate 12.

The mask 14 is irradiated with light from above and the substrate 12 is also irradiated with the light from its reverse surface side. At this time, if the pattern has a defective part through which the light is not transmitted, the part becomes dark. Then, a decision circuit decides the quantity of light from the mask 14 to inspect whether there is a defect or not. Thus, the mask having the light reflection part and light transmission part corresponding to the substrate of the substrate is superposed on the substrate, so a defect in the pattern is inspected at a high speed with high accuracy.

Title: Optical '00' cut adder
Inventor: SUGIMURA YUKICHI
IPC: G06F7/508
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a high speed binary adder using optical OR gates of about five gates or less even when the number of digits is increased. SOLUTION: In the addition of binary numbers, an eleven carry signal in each two digits is sent to an objective digit and to one digit lower than the objective digit and a carry signal to one digit lower is cut out in a carry signal generation source by inputting an LED(light emitting diode) grid light based on an intermediate '00' signal to a NAND gate P71 consisting of a reverse phototransistor (PTR). A carry signal to the objective digit is additionally cut out immediately before its arrival by interrupting an objective digit transistor(TR) in a two-output PTR by a '00' signal which is one digit lower. Preferably one of LED grids is connected to the plus side through a resistor and the other is connected to the minus side by a NAND gate indicating the intermediate '00' signal.  The operation time of an LED can be neglected and a binary adder consisting of five gates can be attained by the optional number of digits. As compared with a carry look-ahead binary adder, the above binary adder has almost a half of gates and 1.4 times of speed in the case of 32 digits and has a half of gates and 2 times of speed in the case of 64 digits.

Abstract: PURPOSE: To reduce the band width of video signals by extracting and eliminating the redundancy of the encoded video signals without lowering the quality of video images. CONSTITUTION: A video signal transmission part is composed of a motion compensation circuit 110, a relay circuit 120 and an encoding circuit 130, etc., the adjacent pulse amplitude modulation signals of a small amplitude are encoded to large pulse amplitude modulation samples in the circuit 130 and thus, signal strength is reinforced so as to make a space for transmitting different signals. The function of a gain controllable along with mapping from the pulse amplitude modulation of the large amplitude to the pulse amplitude modulation of the small amplitude and without the mapping is introduced and the function is achieved by supplying amplitude modulation pulses transmitted by a filling circuit inside the circuit 130 to a buffer. The controllable gain function increases the signal strength and thus, reduces the effects of noise fetched in the signals.  Thus, the high resolution TV device of a small band width is made possible.

IPC: G06F3/06
Filed: 1994-04-18
Abstract: PURPOSE:To transfer high-speed data without any skew by arranging plural magnetic disk devices in parallel and storing data sent from high-order devices in parallel. CONSTITUTION:The data sent from high-order equipments are set in an interface circuit input/output part 4, byte by byte, by a high-order interface circuit 5.

The traffic buffer is stored with bits the 0-7 and parity bit in a byte separately and they are written on nine disk drives 1 dedicated to the respective bits. The rotation of the disks of the nine disk drives 1 is mutually asynchronous, so the bit begin to be written on arrival of indexes of the respective disks. Consequently, the data are written from the high-order devices synchronously without any skew and the data transfer speed is easily increased without increasing the transfer speed of the disk drives.

Filed: 1980-06-11
Abstract: PURPOSE:To exercise control suitable to a user by providing a controller which has an oscillator for controlling a heating body at a distance and a receiver which controls the heating body by receiving a signal from the controller. CONSTITUTION:An electric blanket, or the like is provided with a controller which has an oscillator for controlling a heating body remotely without being connected to a heating body 2. The controller 6 consists an oscillating circuit 14 of a transistor 7, oscillation coils 8, electrodes 9 at both their ends, a power source 10, and a band 11. When a user wears the band 11 on his or her arm, etc., to bring the electrodes 9 into contact with the skin, oscillations continue because the skin resistance is initially high, and then the heating body keeps on generating heat. As the user feels warm, the skin resistance decreases, so the oscillations of the controller 6 stop, and the output of the receiver 12 is stopped correspondingly, so that a controller 3 controls the generation of heat of the heating body 2. Thus, the control over the heating body corresponds to the feeling of the user automatically.
