Title: Semiconductor device and manufacture thereof
Inventor: TANI SATORU
IPC: H01L21/331
Filed: 1991-03-08
Abstract: PURPOSE:To stabilize the contact, etc., between wirings by a method wherein the leading-out conductive layer, etc., of resistors and active elements are buried in field oxide films so that the field oxide films may be flush with the leading- out conductive layers, etc., of resistor and active elements CONSTITUTION:Field oxide films 2 are formed to leave active element region 4 parts by LOCOS step, etc., on an Si substrate l and then the field oxide films 2 are etched away to form resistance regions 3. Simultaneously with said steps, the peripheral parts exposing the Si substrate 1 are etched away to be expanded for the formation of the active element region 4 parts. Next, the first polycrystalline semiconductor layers 5 are formed on the whole surface of the Si substrate 1 and then the surface is polished so as to make the polycrystalline semiconductor layer 5 in the resistance regions 3 and the active element regions 4 flush with the field oxide films 2. Through these procedures, the surface where active element, resistors are formed can be flattened thereby enabling the stable contact, etc., between wirings to be made.

Title: Refrigerator
Inventor: NAKANISHI KEIJI
IPC: F25D11/02
Filed: 1992-02-28
Abstract: PURPOSE:To improve the reliability of the performance of the compressor at the initial stage following turning on of power and simplify the constitution of the means of releasing heat required in a refrigeration cycle. CONSTITUTION:When the compressor 6 is run initially following turning on of power, the fan 9 is run at a low speed for a specified period of time DELTAT; following an elapse of the time DELTAT, the rotation of the fan 9 is shifted to a regular speed. While the fan 9 is run at the low speed, the amount of heat exchange between the cooler 8 and the air inside the refrigerator decreases and the fall in temperature of the cooler 8 accelerates. With the temperature of the cooler 8 lowered, the pressure at which the refrigerant vaporizes inside the cooler 8 declines so that the increase of the discharge pressure at the compressor 6 is decelerated and a longer time is taken for the discharge pressure to reach. Accordingly the peak value of the discharge pressure becomes relatively lower and, as a result, the torque of the maximum load put on the compressor 6 at the initial stage following turning on of power is lowered.

Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To confirm that an antenna is normally operating by a simple operation method by comparing the receiving level of a receiving signal received by a 2nd antenna with a preliminarily stored receiving level in an antenna normal state about an output signal outputted from a 1st antenna. SOLUTION: When a SW1 is switched in an (a) direction, a transmission signal sent by a 1st transmitter 5 of a TX1 is transmitted from an antenna of an ANT1 through a 1st multiplexer 9.

Title: Optical recording and reproducing device
Inventor: YODA SHIGERU
IPC: G11B7/00
Filed: 1989-02-23
Abstract: PURPOSE:To reduce the number of tracks which cannot be used for additional recording and to make an access time for the additional recording short by providing a means which detects a sync mark and a means which outputs an additional recording reference signal. CONSTITUTION:The plural sync marks recorded on a sector information part in a first sector are detected by the sync mark detection means HD. The additional recording reference signal is outputted in a delayed timing corresponding to a recording length to an additional recording area from the detecting timing of the respective sync marks by the additional recording reference signal output means TC and OG. Therefore, by one of the respective additional recording reference signals corresponding to the respective sync marks obtained from the output means, data can be additionally recorded on the additional recording area of a next sector. Thus, even when the last sync mark cannot be detected, for example, the data can be additionally recorded by the detection of the next sync mark. As the result, the number of tracks which cannot be used is reduced and the access time for the additional recording is made short.

Title: Sheet conveyor
Inventor: SAKURAGI KENKICHI
IPC: B65H7/06
Filed: 1990-02-27
Abstract: PURPOSE:To prevent the failure of feeding of papers and feeding of two papers at one time, etc., by causing a sheet recognition means to generate a sound indicating recognition of sheets after a detecting means detects a sheet and operation of a conveying means is started. CONSTITUTION:After a sheet placed on a sheet carrier is detected by a detecting means 14, operation of a conveying means is started by a drive motor 26. After a fixed time elapses a sheet recognizing means (speaker) 7 generates a sound indicating recognition of the sheet. There is thus no danger of failure of feeding of sheets due to an operator's mistake as is the case when generation of the sound indicating recognition of sheets is simultaneous with the start of operation of the conveying means. Also such an accident is prevented that the operator ignores the sound indicating recognition of sheets and presses a sheet into the conveying means.
