Title: Multilayered board baked at low temperature
Inventor: SUNAHARA KAZUO
IPC: H05K3/46
Filed: 1988-09-29
Abstract: PURPOSE:To obtain a highly accurate resistor by providing a resistor protecting layer between the resistor and an insulating layer, and performing lamination and low temperature baking. CONSTITUTION:A hole is provided in a green sheet 1' and filled with a conductor paste 2'. Then, a resistor protecting layer paste 4', a conductor paste 3', a resistor paste 5' and a resistor protecting layer paste 4' are printed sequentially. A similar unbaked resistor-conductor circuit is laminated and thermally compressed. Thereafter, the board is baked in an atmosphere and completed. A protecting layer 4 prevents the contact of the resistor with an insulating layer, reaction at the time of baking and the deviation of the resistance value from an intended value. Thus the highly accurate resistor is obtained. When crystallized glass frit is added into the conductor paste, adhesion with the insulating layer becomes strong, and exfoliation due to strain with a resistor printed part can be prevented.

Inventor: OKAZAKI TORU
IPC: H05H7/04
Filed: 1991-09-24
Abstract: PURPOSE:To measure accurately a magnetic field in the orbital center through which electron beams can pass in an undulator gap by housing rails being a standard for measuring a magnetic field in the undulator gap. CONSTITUTION:Rails 4 being a standard for measuring a magnetic field are arranged in a gap of an undulator 1, and a carriage 5 on which a measurement element 2 is mounted can moves on the rails 4.

Filed: 1985-11-01
Abstract: PURPOSE:To reduce remarkably power consumption by dividing a CMOS circuit into a plurality of semiconductor region, making each of the semiconductor regions electrically independent, and connecting electric power sources in each semiconductor region in series for power supplying. CONSTITUTION:In CMOS circuit parts 1 and 2, many CMOS logic circuits composed of a P-channel MOS transistor M1 and an N-channel MOS transistor M2 are formed. Each of the CMOS circuit parts 1 and 2 is formed electrically independently with each other, whose electric power source inputs are connected in series, and a source voltage Vcc1 is supplied from the both ends of this series connection. Thus a source current i1 flows to the ground potential through the CMOS circuit parts 1 and 2. An interface (I/F) part 3 is driven directly by the original high source voltage Vcc1, and contains the functions of level-shift and level-conversion, which convert the output and input signal levels of each of the CMOS circuits 1 and 2 into the ordinary CMOS levels. The power consumption of CMOS circuits formed in a semiconductor integrated circuit device can be remarkably reduced, thereby.

IPC: H02P6/06
Filed: 1989-09-20
Abstract: PURPOSE:To perform speed control from zero speed to maximum rotation through a single speed control circuit by limiting the low level of output pulse from an F/V pulse generating circuit to a predetermined level and controlling a motor according to an external speed command. CONSTITUTION:An F/V pulse generating circuit 24 converts the rotation of a motor into a voltage which is then compared with a speed command voltage. In other words, a speed command voltage 68-F/V conversion output 62 is operated and converted through an amplification phase compensating circuit 63 into a voltage to be applied onto the motor which is finally rotated with a rotation specified by the speed command voltage 68. When the speed command voltage 68 is set lower than the low level of the F/V converted output 62, the motor is stopped positively. When the speed command voltage 68 is varied above the low level of the F/V pulse, rotation of the motor can be controlled linearly from 0 to the maximum rotation.

Abstract: PURPOSE:To form a solder bump directly on an electrode simply, to facilitate wireless bonding to improve reliability, by applying ultrasonic waves to fused solder, braking a natural oxide film on the surface of the electrode, and selectively attaching the solder on the electrode. CONSTITUTION:A solder returning path 22 is formed in a solder bath 21, and fused solder 23 is contained. For example, double-surface adhesive tape for high temperature use is stuck to the back surface of a silicon wafer. The wafer is bonded to a glass plate and dipped in the jetting fused solder 23 in the longitudinal direction. An ultrasonic wave vibrator 25 is inserted in the fused solder 23 in the vicinity of the silicon wafer 11, and the ultrasonic waves are applied to the fused solder 23. During this soldering operation, nitrogen gas is made to flow around the wafer at a flow rate of 10l/min. Thus, oxidation of aluminum and thin in the solder, which are constituent elements of an electrodes is prevented. The electrode 33 is exposed out of a passivation film 34 before dipping. After the dipping, however, a solder bump 35 is directly bonded to the electrode 33 and the round shaped bump is formed by this operation.

Abstract: PURPOSE:To eliminate unnecessary waiting time till the temperature rises to a fixing feasible temperature and to eliminate wasteful power consumption at the time of standby by controlling the fixing temperature at the time of standby based on a recording paper housing part to be used next time. CONSTITUTION:When a main power source is turned on, whether or not copying operation is performed is judged. In the case the copying operation is performed, the temperature of a fixing part is set to 180 deg., for example, and in the case the copying operation is not performed or in a standby state, whether or not the recording paper housing part 3a is out of order is judged. In the case that the housing part 3a is out of order, whether or not the recording paper housing part 3b being the next housing part is out of order is judged. In the case the housing part 3a is not out of order and the recording paper 7 exists in the housing part 3a, the recording paper housing part to be used next time is the housing part 3a, so that the temperature of the fixing part 5 at the time of standby is set to be 165 deg., for example, considering a carrying distance. Thus, whether or not the recording paper housing part is out of order and whether or not the recording paper 7 exists are judged, and when the recording paper 7 does not exist in the housing part while being out of order, such judgement is performed concerning the next housing part and the temperature of the fixing part 5 at the time of standby is set.

Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To perform offset compensation of a current detecting circuit, excepting the offset part which is caused by residual magnetic flux of a Hall CT iron core wherein offset compensation is unnesessary. SOLUTION: In a conventional case, in order to compensate offset of a current detecting circuit constituted of a Hall CT2 and an amplification circuit 4, an offset equivalent amount is stored in a storing part 5 before normal operation, and a detection current value which is subjected to offset compensation by substraction 6 of the offset equivalent amount from a detection current from the amplification circuit 4 in normal operation is outputted to a control circuit 7. In this case, the offset equivalent amount caused by iron core residual magnetic flux of the Hall CT2 wherein compensation is unnesessary is also compensated.  Before normal operation, the brakes 8 are applied to a motor 3 driven by an inverter 1, the residual magnetic flux of the Hall CT iron core is demagnetized by applying a current for demagnetization to the Hall CT2, and the offset equivalent amount is stored in the storing part 5. As a result, the offset equivalent amount caused by the residual magnetic flux of the Hall CT iron core wherein compensation is unnesessary is not compensated.
