Title: Manufacture of semiconductor integrated circuit substrate
Inventor: TAKIZAWA RITSUO
IPC: H01L21/306
Filed: 1989-10-13
Abstract: PURPOSE:To manufacture a compound substrate with high yield and efficiency without damaging the polished surface, by a method wherein, after a pair of compound substrates are stacked in the manner in which semiconductor layers face with each other without forming a gap between them, the peripheral parts of the semiconductor layers are etched by dipping the parts of compound substrates in etching solution. CONSTITUTION:Two compound substrates 10 composed of a mechanically or chemically thinned silicon layer and a retaining substrate for retaining the silicon layer are dipped in silicon liquid 8, in the state that the substrates are brought closely into contact with each other so as not to form a gap between them. As a result, a low adhesion part on the periphery of a silicon wafer 21 of each compound substrate, that is, the silicon wafer 21 left in a defective region is etched and eliminated. Thereby the generation of flaw on the polished mirror surface can be prevented, which flaw is caused by exfoliated segments in the following manner; in the process wherein the silicon water 21 is mechanically or chemically thinned and the surface is polished to obtain a mirror surface, the low adhesion part of the wafer 21 periphery is exfoliated. Thus a compound substrate can be manufactured with high yield and efficiency.

IPC: H04N3/20
Filed: 1984-12-20
Abstract: PURPOSE:To prevent the occurrence of the burning of a cathode-ray tube even when the same display is executed for a long time by applying always a bias voltage shifting a display graphic to a deflecting coil voltage corresponding to a picture signal. CONSTITUTION:A bias voltage adding means to apply horizontal vertical direction bias voltages H and V to a horizontal vertical deflecting coil voltage is installed, and by these bias voltages H and V, a picture A is shifted slowly to (b) and (c) positions so as to draw a circle. A shifting speed of the picture A is at the slow period of the time unit extent, and the shifting speed of the picture A is at the extent in which the picture will not sense human being's eyes.

Title: Method and device for treating raw garbage
Inventor: SAIDA YASUNARI
IPC: F26B9/06
Filed: 1993-10-26
Abstract: PURPOSE:To treat raw garbage to make it harmless by a method wherein crushed raw garbage is put into a rotary cylinder whose circumferential surface is of mesh construction to dehydrate and dry it in a high temperature atmosphere so that the garbage is solidified into a spherical pellet. CONSTITUTION:When a transparent single swinging door 14 is closed, the end of a pipe 15 is inserted into a pipe insertion hole 13 formed in the middle of a cover body 12 of a rotary cylinder 5, thereby allowing crushed raw garbage together with water to flow into the cylinder 5 through an introducing pipe. If a crusher is actuated, the raw garbage is crushed and flows into the rotary cylinder, while nearly all the water flows down from small through holes of a punched metal and is discharged from a drain hole. If electric power is supplied, the rotary cylinder rotates at low speeds and the crushed raw garbage is dried and formed into spherical pellets in a high temerature atmosphere generated by an infrared heater, while the garbage is subjected repeatedly to water removal operation and separation operation. As a result, odorless solids can be obtained so that treatment of raw garbage can be performed efficiently.

Abstract: PURPOSE:To correct the effect of thermal resistors upon the density of highlighted pixels under accumulated heat by preparing data for correction of the heat regeneration effect of the thermal resistors using a calculation device, then delaying data by a single line with a delay device and supplying correction data obtained using a calculation part to a correction device and the calculation device. CONSTITUTION:An accumulated heat calculation part 16 calculates the amount of accumulated heat of thermal resistors based on data of highlighted dots instead of data of dots two lines ahead. Then ROM 21 for accumulated heat correction making up a correction device calculates correction data from the calculation part 16 based on image data from ROM 17 for adjacent history correction. Consequently, print density due to the heat accumulation of the thermal resistor is corrected. Next the image data from ROM 21 for accumulated heat correction is transferred to line buffer 22 by a single line, and this transferred data is sequentially converted to each density gradation level using a data conversion part 23. A thermal head with thermal resistors arranged in a single row energizes the resistors in accordance with a pulse of each density gradation level each time the pulse is transferred. Then the thermal head prints an image by a single line as the head moves.
