IPC: H01L29/78
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To suppress the dent formation in a separated insulating film, by a method wherein a protrusion protrudent from a semiconductor substrate in the separated insulating film contains an affected zone, while the etching rate in the affected zone meeting the same requirements is differentiated from that of the part in the separated insulating film excluding the affected zone. SOLUTION: A silicon oxide film 3 is formed on the surface of a trench 2 formed on the main surface of a silicon substrate 1. A separated insulating film 4 made of silicon oxide film, etc., filling up the trench 2 and having a protrusion 4a protruded from the silicon substrate 1 is formed. A part of this protrusion 4a is affected so as to form a nitrified part (affected zone) by nitrifying almost the whole protrusion 4a. The etching rates in a nitrified part 6 and the part in the separated insulating film 4 excluding the nitrified part are differentiated from each other. Thus, the separated insulating film 4 can be protected by etching the part in the separated insulating film 4 excluding the nitrified part 6 as well as the other parts composed of the same construction material as that of the former part.

Title: Method for insulating electric machine winding
Inventor: KANOU YASUSHI
IPC: H02K15/12
Filed: 1977-12-26
Abstract: PURPOSE: To obtain a winding with stable adhesive and dielectric strengths of isulation at high temperatures by coiling a main insulating basic material containing a resin-hardening catalyst about the winding-conductor which is already applied with strand-insulation provided by a heat-resisting film or enamel, and then impregnating it with a thermosetting resin.  
     CONSTITUTION: A winding-conductor, applied with strand-insulation provided by a heat-resisting film or enamel, is coiled with a main insulating basic material which contains a suitable quantity of a heteocycle-producing-catalyst and then is impregnated with a thermosetting resin consisting of a polyfunctional epoxy-compound  and a polyfunctional isocyanate-compound. Since the conductor coated with the  heat-resisting film or the enamel is impregnated with only a small amount of the  resin, the resin between the winding conductors is also hardened by the catalyst  contained in the main insulating basic material, thus the dispersions of the adhesive  and the dielectric strengths of the resin are reduced and a winding which is stable  and reliable at high temperatures can be obtained.

Filed: 1995-06-22
Abstract: PURPOSE: To detect a frequency deviation between a transmitter and a receiver, which occurs at the time of demodulating a digital signal in PHS, at high speed. CONSTITUTION: An inputted carrier signal is A/D-converted in an A/D-converter 11, is quadrature detected by a detector circuit 12, is stored in a first storage circuit 13, is band-limited by a band-pass filter 14 and is stored in a second storage circuit 15.

A frequency deviation correction circuit 18 repetitively corrects the frequency deviation as against data of the second storage circuit 15 in accordance with the estimated value. Data which the correction circuit 18 corrects at the time of detecting the frequency deviation is data of the second storage circuit 15 which has less data than the first storage circuit 13. Thus, the frequency deviation can be detected at high speed.

Abstract: PURPOSE: To always keep the temperature of the photoreceptor in the range within which the excellent electrostatic properties can be obtained, by ventilating the waste heat of the fixing device to the side of the photoreceptor or exhausting the waste heat outside the main body of the copier according to the fact that the temperature of the photoreceptor is higher or lower than the fixed level.  
     CONSTITUTION: When the copying starts, the photoreceptor drum 10 rotates in the direction of the arrow S. The measured value obtained through the temperature detector 24 is supplied to the control device. And in case the value is ≤25°C, the fan 23 is rotated clockwise by the control device, air is sent toward the arrow (t) within the duct 22. The air heated by the waste heat of the fixing device 18 is sent near the drum 10 to increase the temperature of the drum 10 up to 20W25°C. When the temperature of the drum 10 exceeding 25°C is detected by the detector 24, the fan 23 is rotated counterclockwise by the control device. Then the heated air near the drum 10 is exhausted outside the main body of the copier, and thus the temperature of the drum 10 is not increased any more.

Abstract: PURPOSE:To reduce considerably the used amount of fuel when a defective pallet is found in a group of pallets in a Dwight-Lloyd sintering apparatus, by placing a heat resistant cover over the grate of the defective pallet on the front side of a firing furnace before exchanging the pallet. CONSTITUTION:When the defective pallet 2' is found in the group of pallets 2, a heat resistant cover 14 having a fixing part 13 formed by bending one edge downward is placed over the grate 15 of the pallet 2' so that the part 13 is inserted in the gap 16 between the pallet 2' and the preceding pallet 2 when the pallet 2' reaches a curve track 3.
