Title: Manufacture of semiconductor device
Inventor: NAKAJIMA KAZUO
IPC: H01L21/205
Filed: 1978-12-28
Abstract: PURPOSE: To obtain the epitaxial active layer having fewer defects such as dislocation by a method wherein etch-pits are caused to be appeared, the part including fewer etch-pits is cut off selectively, and epitaxial growth is made on thus obtained substrate.  
     CONSTITUTION: After etching the surface of a substrate to be used for epitaxial growth so as to make etch-pits appeared, the part of the substrate with low density of etch-pits is cut off selectively and visually. When the etch-pits are small and shallow, the forms of the etch-pits are removed through the etching by mirror abrasive liquids and then epitaxial growth is made directly. When the etch-pits are large and deep, epitaxial growth is made after performing melt-back, for example. Furthermore, in some cases epitaxial growth is made after developing a buffer layer.

IPC: B41J2/44
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanning device and image forming device which prevent a scanning line from curing and is free from unevenness in pitch in the vertical scanning direction. SOLUTION: A 1st mirror 26 reflects a laser beam LB and makes it incident on a mirror surface 34 of a rotary polygon mirror 32, and also reflects the referenced beam from the mirror 34, the reflected beam from the mirror 34 is reflected to the 1st mirror again, so the angle θ of the incident beam can be held small as specified to prevent a scanning line from curving. A 4th mirror 24 and a reflecting mirror 38 are rotated to adjust the direction of the reflected laser beam LB, so the incident position of the laser beam LB made incident on a cylindrical mirror 40 can be adjusted to an incident point 40. Consequently, the cylindrical mirror 40 can securely correct pitch unevenness due to a surface tilt of the rotary polygon mirror 32 and an excellent image is obtained on a photoreceptor drum 12.

Title: Electron beam irradiating device
Inventor: TSUKAMOTO TETSUO
IPC: H01J37/20
Filed: 1987-07-01
Abstract: PURPOSE:To improve the accuracy of setting the electron beam irradiating position by operating an electrostatic prism system arrang-ed in the device from the outside of a box body of the device. CONSTITUTION:The setting of the electron beam irradiating position is carried out by moving an electrostatic prism system. Since the electrostatic prism system is furnished in a box body of a vacuum ambiance which composes the electron beam irradiating device, the work of setting the irradiating position is very complicated if the operation of the electrostatic prism system can be done only inside the box body. On the contrary, by moving the electrostatic prism system from the outside of the box body, the accuracy of the irradiation can be improved simply. The electrostatic prism system is operated by a movement mechanism 11 furnished outside the box body. The movement mechanism 11 can move the electrostatic prism system in the desired direction through moving rods 12 and 13 which are vacuum-separated by bellows 14, and a gyroscopic holding rack.

Title: Measuring device for shape of opening
Inventor: AZUMA KAZUO
IPC: G01B7/28
Filed: 1980-11-26
Abstract: PURPOSE:To quickly measure the shapes of openings made in pressed panels with accuracy by the use of a non-contact type eddycurrent displacement detection probe. CONSTITUTION:A forming block 6 is attached to each pipe 5, at the position where measurement is made, of model gauges 1-4 for use in openings where a windshield glass, rear window glass, a front door or a rear door is fixed. An eddycurrent type displacement detection probe 7 is incorporated into the block 6. In addition, when the gauges 1-4 are installed in the openings, variation of the voltage from the probe 7 is used to detect how much the gap between an object 8 to be measured and the probe differs from a normal dimension. In this case, each size of the gaps is converted 12 into a voltage amount so that whether or not these gap dimensions are within a certain predetermined value is separately judged 14. The results are outputted to a printer 15 and so on.

Abstract: PURPOSE:To increase generated output of the whole system by providing a compound turbine, which has coaxially positioned steam turbine for thermal generation and a binary turbine utilizing a low boiling point medium, and also providing a plant which operates said compound turbine. CONSTITUTION:Steam separated by a steam separator 1 is sent to a steam turbine 2 as in the past.

The low boiling point medium, being turned into high pressure steam, is put to work in a binary turbine 5 and then condensed by an air-cooling condenser 6, however, prior to this condensation, a part of exhaust is used to cool a binary hermetic type turbine generator 15. After being once recovered into a hot well tank 7, the condensed medium is set to the heat exchanger 3 again, by a liquid supply pump 8 while it is led to pass through a preheater 9 on its way to the exchanger 3 for recovering and effectively using exhaust heat from the steam turbine 2.

Abstract: PURPOSE:To stably and rapidly stop a moving boyd by detecting the variation of a moving state due to a braking force applied to the body, and predicting the variation of a future moving state on the basis of the detcted signal to further apply a suitable braking force. CONSTITUTION:When a controller 10 enters an operation for stopping the rotation of a disc 1 on the basis of a command from an exterior, the movable piece 91 of a switching circuit 9 is switched from a contact 92 to a contact 94 to apply a control voltage to become reverse rotation to the regenerative state through an amplifier 11 to a motor 12.l The pickup rate of a regenerated digital signal obtained from a pickup 2 decreases due to the deceleration of the rotation of the disc 1. Thus, the counted value of a counter 5 is sequentially decreased, and when the counter value becomes the prescribed value, the output of a comparator 7 shifts from L level to H level. After the output of the comparator 7 shifted to the H level, the controller 10 controls the circuit 9 to further apply a braking voltage to the motor 12 for the prescribed period.
