Title: Superconductive wire
Inventor: TANAKA YASUZO
IPC: H01B12/16
Filed: 1988-02-29
Abstract: PURPOSE:To improve processability, decrease weight, increase critical current for reducing dispersion of superconductive wire by selecting Al or Al alloy as a material for covering tube. CONSTITUTION:For superconductive wire, comprising a single or plural combined element wires 11 each of which is composed of plural superconductive element wires 11 in a metal matrix and having a covering tube 12, or superconductive wire, comprising an assembly of the superconductive wires described above and having another covering tube 12, Al or Al alloy is selected for the material of the covering tube 12. The selection of Al or Al alloy makes the resultant superconductive wire lighter than that in which stainless steel or high strength steel is used as the material of the covering tube; further more, Al or Al alloy increases thermal conductance of the covering tube 12 to improve its cooling effect of heat generated locally. This selected use of Al or Al alloy as the material for the covering tube 12 can give superconductive wire of a long size, which is superior in processability and which has a low melting point at welding.

Title: Demodulation method and demodulator
Inventor: TSUDA HIROKI
IPC: H04L27/233
Filed: 1995-03-07
Abstract: PURPOSE: To surely perform reception demodulation by time dividing one sampling period, detecting the reception signals of different carrier frequency offset ranges, performing a reception processing only for a detection section after detection and performing carrier synchronization. CONSTITUTION: An address control circuit 12 controls address signals in a time division processing for each sampling until the reception signals are detected and supplies them to first and second memories 5 and 8 and an offset generation circuit 13. The address signals correspond to frequency control signals which are the output of the circuit 13 and the time division sections for each sampling and the respective time division sections indicate the detection processing of the reception signals of the different carrier frequency offset ranges.  Then, when signals are detected in a signal detection circuit 11, the circuit 12 sets the processing of the time division section in which the signals are detected as an optimum processing section for minimizing a carrier frequency offset in the input of a carrier regenerative circuit 14 to the corresponding memories 5 and 8 and the circuit 13. After the reception signals are detected, the time division processing for each sampling is stopped and a synchronization processing is performed only to an optimum time division processing section.

IPC: H01L21/02
Filed: 1986-03-06
Abstract: PURPOSE:To remove static electricity from wafers for decreasing dust adhered on the wafers and to avoid problems such as dielectric breakdown due to static electricity, by providing a wafer transporting mechanism with a static eliminator. CONSTITUTION:A static eliminator 3 comprises brushes 5 formed by stranding conductive small-gage wires such as carbon fibers and a table 6 on which the brushes 5 are fixed and through which electric charge taken up by the brushes 5 is discharged to the earth. When a support bar 3 on which a wafer 1 is fixed is moved along a rail 4 in the direction as indicated by the arrow A, the brushes 5 of the static eliminator 1 come close to or in contact with the rear face of the wafer 1, whereby static electricity is removed from the wafer and discharged to the earth. Since the static absorbability is eliminated in this manner, any dust which has been attracted by static electricity of the wafer 1 will fall down automatically by gravity.

Title: Transmission system for video signal
Inventor: SOMEYA IKUO
IPC: H04N19/85
Filed: 1990-02-28
Abstract: PURPOSE:To improve the resolution of a reproduced original picture regarded being almost at a standstill by applying subsampling to a high frequency component of a video signal to cause band compression and sending the result when the original picture is consecutively at a standstill over a prescribed number of fields. CONSTITUTION:A detection circuit 26 integrates a moving control signal MC 1 as to all picture elements of a full pattern for each field period and generates a still signal ST whose level goes to a high level 1 when the integration value is smaller than a prescribed value and the full pattern is regarded to be at a standstill and whose level goes to a low level 0 when the full pattern is not regarded to be at a standstill. When the original picture is continuously at a standstill over prescribed number of fields, the high frequency component is sent while being subject to band compression with sequential subsamapling together with a video signal whose high frequency component of the original picture is eliminated. Thus, the resolution of a reproduced picture of the original picture regarded to be almost at a standstill is improved.

Filed: 1988-03-02
Abstract: PURPOSE:To surely prevent a person from leaving a room without having a key by outputting a prescribed information command signal with an information control means when it is detected that a door is unlocked from the inside, receiving the command signal with a warning device provided at a door or near the door and warning the key forgetting, in a door which automatically becomes the locking condition at the time of closing the door. CONSTITUTION:When an unlocking detecting part 5 of a main warning part 1 detects that a person unlocks a lock to leave the room and outputs it to an informing control part 9, a control part 9 decides whether or not the person is in the room based on the detected result from a person informing part 7.

Reversely, when plural persons are in it, an informing signal is not outputted and a key 23 is obtained as it is. At the time of leaving the room, when other person does not remain, the placing forgetting of the key 23 is informed and it is surely prevented that the person forgets the key 23 and leaves the room.
