Title: Method of trimming resistor film
Inventor: SUZUKI KATSUNAO
IPC: H05K1/16
Filed: 1988-03-31
Abstract: PURPOSE:To prevent dust from being produced by shortening the time for trimming by forming a notch in a resistor film along a line surrounding a region of the resistor film to be removed and prohibiting said region from being supplied with a power after the formation of the notch. CONSTITUTION:Resistance between electrodes 11 and 12 are monitored, and at the same time a notch 14a is formed from one marginal edge of a resistor film 13 toward a direction normal to a straight line which defines an interelectrode distance. Then, the direction of the notch 14b is changed, and a new notch 14b is formed in a direction parallel to the straight line defining the distance between the electrodes 11 and 12. The notch 14b is extended, with the resistance between the electrodes 11 and 12 being monitored, to its length where the resistance is accurately purposed one. Thus, the resistor film 13, in which the resistance between the electrodes 11 and 12 is the purposed one, is yielded. Hereby, trimming time is shortened to prevent any dust from being produced.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To close a tracking loop in a short time even reduced in eccentric quantity by outputting a signal for kicking an optical pickup lens to a tracking actuator and opening/closing a switch according to continuous tracking error signals from the optical pickup. SOLUTION: A control signal 7 outputs the signal for kicking the lens of optical pickup 1 to an amplifier 5 and measures the amplitude of tracking error signal. Based on the amplitude of plural continuous tracking error signals, a switch 4 is changed from OFF to ON and tracking is closed. The control part 7 is provided with a differentiation circuit for the tracking error signal from a phase compensation circuit 3 and a comparator circuit for outputting a rectangular wave when the voltage output of this circuit is higher than a fixed value, and the tracking loop is closed by stably turning on the switch 4 at the center of track. Since the tracking error signal can be provided by kicking the lens even with reduced eccentric quantity, the tracking loop can be speedily closed.

Title: Manufacture of josephson tunnel junction
Inventor: KURODA KENICHI
IPC: H01L39/24
Filed: 1991-04-15
Abstract: PURPOSE:To simply form a Josephson tunnel junction having minute patterns by continuously forming a lower superconductive film and barrier layer through the same metal mask. CONSTITUTION:A lower superconductive film 2 and barrier layer 4 are continuously formed in the same vacuum tank by the use of the same metal mask, i.e. without exchange of the metal mask. Then, after a sample is taken out from the vacuum tank into the air and the metal mask is exchanged, an insulating layer 6 is formed in the same vacuum tank. Therefore, a metal mask exchange mechanism used heretofore for exchanging the metal mask, as a vacuum state is maintained in the tank, becomes unnecessary. Thus, it is possible to simply form a Josephson tunnel junction having minute patterns.

Title: Microwave semiconductor oscillator
Inventor: MORI TETSUO
IPC: H03B9/12
Filed: 1980-06-12
Abstract: PURPOSE:To enable electric tuning, by locating a subresonator with a varactor diode nea a dielectric resonator. CONSTITUTION:A subresonator 10 of microstrip line is located in parallel with a gate electrode transmission line 5 to constitute a positive feedback circuit by a dielectric resonator 7. To change the reactive component of a subresonator 10 electrically, a varactor diode 11 is loaded at one end of the subresonator 10, and another end of the varactor diode 11 is short-circuited with a 1/4 wavelength microstrip line. Further, the line length l1 of the subresonator 10 is set to about 1/2 wavelength to obtain strong coupling with the dielectric resonator 7. Since a BPF consisting of the dielectric resonator 7 acts like a positive feedback circuit from a drain electrode D to a gate electrode G, this oscillator oscillates almost at the resonance frequency of the dielectric resonator 7. Electric tuning is possible by changing the bias voltage of the varactor diode 11.

Abstract: PURPOSE:To prevent that an impedance generated by the resonance of the capacity of a Peltier element in an operating region with the inductance of a wire is increased by a method wherein a capacity is added in parallel between one electrode and the other electrode of the Peltier element. CONSTITUTION:A Peltier element 4 and a semiconductor element (e.g. a laser diode) 8 are assembled collectively. An electrode on the side of the Peltier element 4 for the semiconductor element 8 is connected to an external extraction lead 13 by using a wire 16. One electrode 3 of the Peltier element 4 is connected equivalently between the electrode for the semiconductor element 8 and the external extraction lead 13. At the mounting apparatus of such a semiconductor device, a capacity 17 C1 is added in parallel between one electrode 3 and the other electrode 5 for the Peltier element 4, and the parallel resonance frequency of an inductance L3 by the wire 16 with a capacity CS between the electrodes 3, 5 of the Peltier element 4 is shifted to be lower than the operating frequency of the semiconductor element 8. Thereby, the impedance of an operating current circuit at the semiconductor element 8 is reduced.

Abstract: PURPOSE:To ease difference between thermal expansion coefficient of a semiconductor device and the heat sink, by laminating three layers into the heat sink. CONSTITUTION:The semiconductor device has a power semiconductor element 3 fixed through a heat sink laminated into three layers over a metal substrate 1. The heat sink 2 consists of plates of copper 4, invar 5 and copper 4 which are extended into given thicknesses and are stamped into given sizes respectively. The thermal expansion coefficient of invar 5 is 1.5X10<-6>/ deg.C. According to this structure, and by selecting ratios of the thicknesses of the three laminated plates of the heat sink being 1:1:1, the thermal expansion coefficient becomes 11X10<-6>/ deg.C, which is smaller than that of the copper 4. Moreover, by selecting the ratios of 1:3:1, the thermal expansion coefficient becomes 6X10<-6>/ deg.C, being near that of silicon. Thus, it is prevented that wax for fixing the silicon power semiconductor element may be deteriorated, and the heat conductivity and therefore heat radiating ability can be improved.
