Title: Manufacture of semiconductor device
Inventor: ANEZAKI TORU
IPC: H01L27/108
Filed: 1992-02-18
Abstract: PURPOSE:To obtain a semiconductor device including a sufficient amount of impurity in an electrode of a fin-type capacitor without changing the film thickness by heat-treating the sample with an impurity containing interlayer film being brought into contact with a semiconductor film and then by diffusing in solid phase an impurity contained in the impurity containing interlayer film. CONSTITUTION:With semiconductor films 11, 13 and 16, which will become an accumulated electrode 18 of a capacitor, being brought into contact with impurity containing interlayer insulating films 10, 12, 14 and 17, the sample is heat-treated and thereby an impurity contained in the impurity containing interlayer insulating films 10, 12, 14 and 17 are diffused in solid phase into the semiconductor films 11, 13 and 16. Therefore, when a resistance of the semiconductor layers 11, 13 and 16, which will become the accumulated electrode 18, is made lower, an impurity does not pass through the semiconductor films 11, 13 and 16 and thereby enough amount of impurity can be doped. Because of this, enough amount of impurity can be doped only with one time heat treatment and therefore the surface of the semiconductor films is not oxidized during diffusion of an impurity and eventually, the accumulated electrode of the desired thickness can be formed.

Title: X-ray high voltage device
Inventor: SHIBATA KUNIO
IPC: H05G1/10
Filed: 1982-02-28
Abstract: PURPOSE:To enable a desired voltage to be obtained without any fear of heating, and enable the size of the whole of an X-ray high voltage device to be made smaller by supplying an a.c. electric power to an auto-transformer for X- ray tube voltage adjustment at time intervals related to X-ray photographing operation. CONSTITUTION:An X-ray photographing power switch (PSW) is connected between an auto-transformer (AT) and a line switch (LSW). Even when the line switch (LSW) is closed, as far as the X-ray photographing power switch (PSW) is not closed, there is no possibility that a short-circuit current flows through a brush which touches the winding of the auto-transformer (AT). In addition, since a thyristor which is a component of the power switch (PSW) is made conductive by applying an X-ray photographing signal to the gate electrode of the thyristor, and since X-ray photographing time usually is as short as around 0.1sec, the heating value of the auto-transformer (AT) generated by a short-circuit current flowing through the winding of the auto-transformer (AT) becomes negligibly small.

IPC: B41J2/44
Filed: 1986-02-14
Abstract: PURPOSE:To prevent optical fatigue and a fog caused by a bias current for compensating temperature under the existence of a bias current by reducing a bias component included in an optical output (optical output produced by a bias current). CONSTITUTION:A collimate lens 2 makes light coming out of a semiconductor laser 1 which is modulated by a picture signal into parallel light, a f.theta lens 4 converges reflected light from a polygon mirror 3 which reflects parallel light while it is rotating at high speed. Then the light emitted from the lens 4 is reflected by a fold mirror 6, and an image is formed on the surface of a photosensitive drum 5. In that case, a thing obtained by reducing the reflectance of the fold mirror 6 is used as an optical intensity dropping means. Thus the optical output at an off-level can be dropped without reducing the bias current, and a fog and optical fatigue due to a photosensitive body can be reduced without adversely affecting a temperature compensating function.

Abstract: PROBLEM TO BE SOLVED: To improve generation efficiency, reduce the size and improve durability by arranging an unbalance wheel on the same axis as gears constituting an accelerating wheel train. SOLUTION: A rotation means 1 is constituted of a rotation center and an unbalance wheel with eccentric center of gravity, the rotational motion of the rotation center 1 is accelerated with an accelerating wheel train 2, and the rotor of a converter A3 as a generation mechanism is rotated to generate alternating current.

A converter B8 is supplied with energy by the driving circuit 7 and operated and the motion of this converter B8 is transmitted with a deceleration wheel train 9 to a hand 10 to indicate time. As half-wave rectification is used for the rectifying circuit 4, the kinetic energy of the unbalance wheel can be raised by reducing magnetic brake so that generation efficiency is raised. Also as the unbalance wheel is arranged on the same axis as a gear constituting the acceleration wheel train 2, thinning of the watch becomes possible.
