Title: Integrated circuit and manufacture thereof
Inventor: SHIODA TAKAO
IPC: H01L21/60
Filed: 1987-08-26
Abstract: PURPOSE:To inhibit the damage of an element, and to maintain excellent characteristics by joining a connecting section consisting of an oxide superconductor mounted to a lead section in the element and a wiring section composed of an oxide superconductor set up to a wiring substrate by using a condensing heating means. CONSTITUTION:A circuit substrate 2 is placed onto the top face 3a of a wiring substrate 3. Each connecting section 7... for lead sections 5... formed onto the underside 2a of the substrate 2 is brought into contact respectively with a wiring section 8 shaped to the top face 3a of the substrate 3 at that time. Each connecting section is heated by a condensing heating means through the substrate 3 from the lower section of the substrate 3 composed of a transparent material. Each connecting section is heated by condensing beams to a specified spot diameter by passing beams through a lens 11 from a light source 10, and the connecting sections 7 in the contact sections and the wiring section 8 can be joined firmly without damaging an element 4 on the substrate 2. The connecting sections 7 and the wiring section 8 are shaped from an oxide superconductor, and the substrate 3 is cooled properly, thus maximally putting characteristics such as the high-speed arithmetic operating properties of the element 4 to practical use.

Title: Noise eliminating device
Inventor: NISHINO SHOICHI
IPC: H04N5/21
Filed: 1986-09-09
Abstract: PURPOSE:To eliminate a noise component remaining at the edge part of a signal to just this side of the edge part, by performing the amplitude limitation of a signal whose low-pass area is attenuated, and subtracting the Now-pass area after being exaggerated from an input video signal. CONSTITUTION:Before applying the amplitude limitation on a high-pass area component except a component in the neighborhood of the maximum frequency of a reproduced video band area taken out so as to extract the noise component of micro level by a first filter 7, by an amplitude limitation circuit 9, the low- pass area component is suppressed by a second filter 8, and the high-pass area is exaggerated. Thereby, it is possible to shorten a period when the amplitude limitation is applied on the signal having large level change such as the edge part of the signal, and also, the noise component of micro level is recovered to the state of the output of the first filter 7 by a third filter 10 having a characteristic opposite to that of the second filter 8. In this way, it is possible to obtain an effect to eliminate the noise to just this side of the edge part.

Title: Hybrid driver
Inventor: NAGAYAMA KAZUTOSHI
IPC: B60L50/15
Filed: 1994-09-06
Abstract: PURPOSE: To realize a field control circuit using a simple chopper circuit by employing a hybrid excitation permanent magnet generator thereby controlling the current being fed to a DC field winding. CONSTITUTION: AC three-phase current generated from a hybrid excitation permanent magnet generator (HPG) 51 is fed through a rectifier 53 to produce a DC current which is fed to a battery 54 and a drive invertor 55. The AC three-phase current is also fed through an auxiliary rectifier 57 for exciting power supply to produce a DC current which is then fed through a chopper circuit 58 to an exciting winding 51a. Voltage to be generated from the HPG 51 can be regulated by decreasing the exciting current to cause demagnetization or increasing the exciting current to cause magnetization. Consequently, power generation of the HPG 51 can be controlled by simply controlling the exciting current being fed to the exciting winding 51a.

Abstract: PROBLEM TO BE SOLVED: To adjust crushing size and weight distribution by a method wherein, when impulse waves generated by an energy converter are transmitted to a rod-shaped semiconductor raw material in a liquid medium, the distance between the energy converter and the semiconductor raw material and pulse energy and pulse rise time of the impulse waves are specified. SOLUTION: When one or more impulse waves generated by an energy converter are transmitted to a rod-shaped semiconductor raw material in a liquid medium, the distance between the energy converter and the semiconductor raw material is set to 1-100 cm, and the pulse energy of the impulse waves is set to 1-20 kj, while the pulse rise time until when the pulse energy reaches a maximum value is set to 1-5 μs. At this moment, impulse waves are generated electromagnetically or piezoelectrically by, for example, a charge or electric discharge. In this method, a small portion of the rod is not broken and the whole portion of the rod, on which impulse waves are applied, can be evenly broken. Cavitation bubbles are generated following the impulse waves, which waves produce surface cleaning effect on the semiconductor raw material.

IPC: H01H37/32
Filed: 1987-08-28
Abstract: PURPOSE:To allow the sure temperature detection with a simple structure by providing a temperature detecting section made of a high-temperature superconductor and a magnet moved by the Meissner's effect of the superconductor and a limit switch operated based on the position of the magnet. CONSTITUTION:A temperature detecting section 1 is made of a high-temperature superconducting material, and a magnet 2 is arranged near the temperature detecting section 1. When the temperature of the temperature detecting section 1 is lower than the critical temperature, the temperature detecting section 1 becomes superconductive and repels the magnet 2 by the Meissner's effect to close a limit switch 3a. When the temperature is higher than the critical temperature, the temperature detecting section 1 becomes ordinarily conductive, the Meissner's effect disappears, and the magnet 2 is withdrawn by a spring 4, the limit switch 3b side is closed and the 3a side is opened. A temperature switch is thereby obtained with a simple structure.
