Title: Diffusion treatment of semiconductor wafer
Inventor: NAKADA KIMIO
IPC: H01L21/00
Filed: 1982-12-14
Abstract: PURPOSE:To prevent the generation of a thermal strain, to keep the temperature of a semiconductor wafer in a high temperature region constant at all times and to obtain a junction in uniform depth and uniform resistivity extending over the whole surface of the wafer by preheating the wafer so that its temperature is elevated slowly in the low temperature region of the same oven, transferring its to the high temperature region and diffusing an impurity while heating it at a high temperature. CONSTITUTION:A heater 5A is controlled so that the temperature of the low temperature region 5 is kept at an initial temperature (such as 600 deg.C) at its maximum where the wafer is not thermally strained. The semiconductor wafers (W) are loaded on a boat (B), and charged into the low temperature region 5 from an oven inlet. Temperature distribution is stabilized, and the temperature of the low temperature region 5 is elevated step by step or in a rampy manner up to a first temperature (such as 1,000 deg.C) higher than the initial temperature by the heater 5A. The boat (B) is moved to the high temperature region 4, and the impurity is diffused according to a predetermined manner. Both the high temperature region 4 and the low temperature region 5 are kept at fixed temperature during the diffusion. Diffusion is completed, the boat (B) is moved into the low temperature region 5, the region 5 is cooled slowly, and the temperature of the region 5 is dropped step by step or the rampy manner up to the initial temperature by the heater 5A.

Title: Driving system of liquid crystal display type image receiving device
Inventor: MAEZAWA SHIYUUJI
IPC: G09G3/36
Filed: 1982-12-13
Abstract: PURPOSE:To display a video by a simple driving circuit by constituting so that a driving signal applied to a scanning electrode takes the selective potential in a selective period, and takes the non-selective potential which is different before and after the selective period, in a non-selective period. CONSTITUTION:Each output of a shift register 82 determines a selective potential period corresponding to each scanning electrode Y1-Ym. In each selective period, a selective potential signal SEL is outputted to each scanning electrode. Each output TY1-TYm of a shift register 83 determines the second non-selective period corresponding to each scanning electrode. In this state, as for an output of an analog switch 84, the first non-selective potential signal NEL is outputted to each scanning electrode before the selective period, and the second non-selective potential signal HEL is outputted after the selective period. In this case, VG and VH of the second non-selective potential are set so that a potential difference applied to an MIM display of a picture element immediately after a picture is written becomes the lowest on an average. In this way, a video can be displayed by a simple driving circuit.

Abstract: PURPOSE:To enhance the performance of spindle motor and disc unit by driving a screw into a pipe part and fixing the spindle motor to the disc unit while sandwiching the disc unit, at the mounting part thereof, by means of the step part of shaft and a flange. CONSTITUTION:A spindle motor 20 is fixed to a disc unit A by inserting a pipe part 31 into a fixing hole 34 made through the base plate (part to be fixed) of the disc unit A with no rattling and then screwing the external thread 331 of a fixing screw 33 into the internal thread 311 of the pipe part 31 thereby sandwiching the base plate P by means of the step part 211 of a shaft 21 and a flange 32.
