Title: Transmission system for return signal of b type fault locator
Inventor: MATSUSHITA AKIHIRO
IPC: G01R31/08
Filed: 1980-12-10
Abstract: PURPOSE:To transmit a detected point of surge easily and precisely through a low-speed digital circuit, by removing sampling distortion in sampling the detection point of surge generated when an accident of a transmission line occurs. CONSTITUTION:Before the generation of surge, a frame generator FG sends a unique pattern to be synchronized with a reception side in terms of phase. Once a surge (a) is detected by a surge detector, a detection output (b) is applied to a terminal, and consequently a counter COT starts counting pulses from a reference oscillator OSC and stops the counting operation by a next sampling pulse from a clock generator CG (counting time ts). The COT to be output (b), the frame generator FG interrupts the transmission of a synchronizing signal, and generates and transmits a code sequence with frame constitution. The reception side, on the other hand, discriminates surge information once detecting a start bit by a code checker C, and then extracts data; and an arithmetic circuit CA computes time relation with the surge signal of its office inputted through a delay circuit T to spot an accident point.

Abstract: PURPOSE:To improve the operability by displaying the remainder number of papers to be recorded with flashing during input of an input means when an abnormal state of the device is displayed. CONSTITUTION:A segment display device 46a displays the copy number and displays ''E'' when the device is in trouble. If a copy number setting key 46b or 46c, a clear/stop key 46d, or a copy key 47e is depressed when the device is in trouble, the display on the display device 46a is switched to display the remainder number of papers to be copied with flashing. Consequently, the remainder number of papers to be copied is detected with only depression of the key though ''E'' indicating that the device is in trouble is displayed, and flashing display indicates that the device is not normal.

IPC: C30B23/06
Filed: 1986-07-24
Abstract: PURPOSE:To strictly control the crystal growth by arranging a raw material for crystal growth at a high-temp. region, arranging a crystal growth region at a low-temp. region, and forming a sharp temp. difference at a boundary between both regions. CONSTITUTION:The raw material for crystal growth is heated, and the vapor is transported to the crystal growth region and supersaturated to grow a crystal. In this process, the crystal growth region (low-temp. part) and the raw material region (high-temp. part) are kept at a fixed flat temp., the crystal growth region at low temp. is arranged at the lower part of a growth device, and the raw material region at high temp. is arranged at the upper part. A sharp temp. difference is set between both regions, hence only the difference between the vapor pressure based on the raw material temp. and the vapor pressure based on the crystal region temp. is used as the driving force for the crystal growth. In this method, specified supersaturation prevails over the whole growth region, the temp. difference is controlled within the range where deposition on the inner wall of the vessel is not caused, and the inner wall of the vessel can be cleaned and stabilized easily and sufficiently to prevent the natural generation of a nucleus.

Filed: 1985-08-10
Abstract: PURPOSE:To eliminate the disconnection of second layer aluminum wirings by allowing the aluminum portion except the aluminum wirings to remain slightly at the aluminum wiring etching time, and converting the remaining portion to hydrated alumina, thereby reducing a step near the wirings. CONSTITUTION:An aluminum alloy film 3 is formed on a silicon oxide film 2, a resist 4 is coated and patterned. Then, the film 3 which is not coated with the resist 4 is etched. A silicon substrate 1 which is so treated as to allow part of the film 3 to remain is dipped in hot water. Thus, the portion not coated with the resist 4, i.e., the remaining film 3 at etching time reacts with the wafer to form an alumina layer 5. The thickness of the remaining film 3 is all alumina is thickness so that the alumina may not eventually remain. When the resist 4 is removed after the layer 5 is formed, the wirings formed of the film 3 and the layer 5 become substantially flat.
