Inventor: INOUE TOMO
IPC: D05B19/08
Filed: 1993-05-14
Abstract: PURPOSE:To correctly and efficiently perform the positioning work of a series of pattern by providing a control means controlling a seam forming means and a relative movement means so that a mark which represents the reference position related to the shape of the pattern can be formed on a product. CONSTITUTION:The data of a seam 2 which represents the reference position is inputted in advance to the seam data of a frame pattern 38. First, the frame pattern 38 is selected to decide the sewing position from the sewing range, and then the sewing is started by pushing a start/stop switch. And the frame pattern 38 including the seam 2 which represents the reference position is sewed. Then, a character pattern 36 is selected to decide the sewing position and start the sewing. A ROM card storing the data of the one-point pattern 34 is attached to the sewing machine and the sewing position is decided by taking the seam 2 representing the reference position as the reference. Sewing is started when the start/stop switch is pushed. Thus, the pattern combining the one-point pattern 34, character pattern 36, and the frame pattern 38 can be completed.

IPC: H02M7/12
Filed: 1988-05-10
Abstract: PURPOSE:To remove pulsation components by detecting the components from the output voltage of a converter, forming the pulsation current of a passive filter on the basis of the component, and supplying it to an active filter provided in parallel with a load. CONSTITUTION:A low pulsation DC power source 1 has a semiconductor converter 2, a reactor 3, a voltage detector 7, and an active filter 12, and supplies a power to a load 8.

Title: Blood component quantitative measuring device
Inventor: KAWAMURA TOSHINORI
IPC: G01G17/04
Filed: 1985-05-27
Abstract: PURPOSE:To prevent a sensor from being used in the nonlinear operation region thereof and enable the sensor to measure a blood component to the approximate limit of the linear region of the sensor. CONSTITUTION:A sensor 1 detects a predetermined blood component in a reactor. Arithmetic means 2A obtains the value of the predetermined blood component from the difference between the outputs of the sensor 1 before and after a blood sample is injected into the reactor. The result of the calculation by the means 2A is displayed on a display 3. Further, the output of the sensor 1 after the blood sample is injected into the reactor is compared with the threshold of an alarm smaller than the limit of the linear operation of the sensor 1 by a prescribed value. When the output of the sensor 1 exceeds the threshold value smaller than the upper limit output value of the linear operation region of the sensor 1 by the prescribed value, comparator means 2B produces an output and an alarm unit 4 operates in response to the output of the comparator means 2B.

Title: Data communication equipment
Inventor: NAGAISHI TOMIO
IPC: H04N1/411
Filed: 1990-04-27
Abstract: PURPOSE:To reduce the entire data processing time by applying full white level data processing being simplifying processing to a special code data. CONSTITUTION:A code data read from a 1st compression coding section 30A is given to a discrimination section 80, in which the data is discriminated to be a full white level data or a black/white data, and in the case of the black/ white data, decoding processing, magnification/reduction processing and coding processing are implemented to the data and the resulting data is sent. However, in the case of the full white level data, the data processing above is not implemented, a fixed full white level data stored in advance in a fixed full white level data generating section 92 is sent. This is because the full white level data is unchanged regardless of any data processing, and the full white level data simply in matching with the coding system and the width of an original has only to be sent. The data processing is simplified by applying bypass processing of the full white data in this way and the entire data processing time is reduced.

Title: Structure of superconducting logic circuit device
Inventor: NAKANE HIDEAKI
IPC: H01L39/22
Filed: 1987-05-12
Abstract: PURPOSE:To increase the circuit operational margin by averting the effect of a parasitic inductance and enhancing the coupling state of control wires by a method wherein an upper layer 1 is formed into the inductor of a logic circuit. CONSTITUTION:A lower electrode 2 comprising a superconducting thin film is connected to a ground plane 5 formed on a substrate 8 through the intermediary of an earth electrode 6 while a tunnel barrier layer for Josephson junctions 3 is formed on the surface of the lower electrode 2. An upper electrode 1 comprising the superconducting thin film is formed and then control wires 4 comprising the superconducting thin film are formed through the intermediary of an interlayer insulating film 11 to form a logic circuit. An inductor required for the logic circuit is formed by extending the upper electrode 1. The inductance of electrodes is increased proportionally to the distance from the ground plane 5. Consequently, when an electrode in a junction part is formed in the lower electrode 2 near the ground plane 5, a parasitic inductance is decreased to increase the operational margin of the logic circuit. In such a constitution, the control wires 4 pass above the upper electrode 1 even in the junction part so that the coupling state of input signals to the logic circuit may be enhanced.

Title: Method and apparatus for detecting mark in exposing of electron beam
Inventor: FUKUDA HISASHI
IPC: H01L21/027
Filed: 1981-07-20
Abstract: PURPOSE:To improve S/N ratio with the same signal amount and to increase positioning accuracy in exposing of electron beams by a method wherein a detection signal is detected and amplified at a certain frequency corresponding to the chopping frequency of the electron beam. CONSTITUTION:An electron beam from an electron gun 1 is scanned on a positioning mark of a sample 6 and, at the same time, the electron beam is chopped by a planking electrode 3 with a frequency of 3.33MHz. Reflected electrons due to thus chopped electron beam are captured by a reflected electron detector 8 and only a signal of 3.33MHz is amplified by a detection amplifier 10. In this way, since the electron beam is chopped and a detection signal is detected and amplified at the chopping frequency, signals during periods where the electron beam comes OFF is completely cut out. Thus, the S/N ratio is improved and it becomes possible to obtain a level of 45dB or so.

Title: Switching power supply
Inventor: OKAGAWA AKINOBU
IPC: H02M3/338
Filed: 1990-04-26
Abstract: PURPOSE:To prevent a large current flow through a switching transistor by connecting a diode with such polarity as a reverse bias is applied to turn a FET OFF, upon throw-in of power supply, through utilization of a voltage induced in an auxiliary winding. CONSTITUTION:An auxiliary winding 12a and a diode 24 are arranged on the secondary of a transformer. When a power supply is thrown in to turn a switching transistor 3 ON for the first time, a voltage having such polarity as increasing the drain voltage of a FET 13 is induced in the secondary winding 12. Since the auxiliary winding 12a is wound such that the black mark point has positive polarity, the voltage induced in the auxiliary winding 12a causes to reverse bias the gate potential of the FET 13 through the diode 24. Consequently, turn ON operation of the FET is prevented thus preventing overcurrent flow through the switching transistor.
