Title: Manufacture of semiconductor device
Inventor: SAITO UMIHIKO
IPC: H01L21/225
Filed: 1984-08-22
Abstract: PURPOSE:To enable shortening of a process and a manufacturing time by simultaneously carrying out thermal diffusion of a wafer coating an emulsion solution which contains plural element for diffusion. CONSTITUTION:An emulsion solution which contains plural elements for diffusion is coated on a semiconductor substrate and thermal diffusion is carried out. For example, using an N type substrate 1, a partial exposure region is formed on a silicon oxide film 2 using a photosensitive resin for selective diffusion and an aperture is provided. An emulsion type solution 3 which contains impurity elements of different conduction type and different diffusion coefficient, e.g., arsenic and boron is coated on the aperture by a spinner and thermally diffused at approx. 1,000 deg.C. Since the diffusion coefficient of boron is greater than that of arsenic, the boron is deeply diffused in the same heat treatment and a transistor of NPN type wherein 1 is an N type, 5 is a P type and 4 is an N type is formed.

Title: Tuning filter proofreading system
Inventor: LUIZ DAVID A
IPC: G01R27/28
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To inexpensively realize the proofreading system of the tuning filter of a spectrum analyzer. SOLUTION: A local oscillator radiation 17, leaking to a tuning filter 20 from a local oscillator 18 via a mixer 16, is used. At proofreading, radiation 17 reads a voltage value V0 of a signal 19 reflected by the tuning filter 20 via a resistance. For obtaining a control current Ic of the tuning filter 20 such that the center frequency of which becomes the frequency of a local oscillator signal 13, control current is swept in a prescribed range and a control current value with which the detection level of the reflection signal 19 becomes minimum is searched. The difference between the current value and the control current value corresponding to the passband center frequency of the tuning filter 20, which is previously stored, is obtained and is set to be the correction value for the control current of the tuning filter 20.  Since an outer signal source and a private wiring are not required for proofreading, a proofreading system can be realized at low cost.

Title: Semiconductor device
Inventor: YAMAGUCHI KESAMITSU
IPC: H01L23/48
Filed: 1985-08-09
Abstract: PURPOSE:To prevent a collar-shaped part form being formed at a press-fit part of a lead wire, while increasing coupling strength of the heat of a connection member to the lead wire, by forming a hole, equipped in one edge face of the head of the connection member in the shape of a conical trapezoid in which the opening part at the edge face serves as the lower base. CONSTITUTION:A head part 3 is made of tungsten, having dimensions of 1mm in diameter and 1.5mm in length. The hole 8 formed at the head 3 is shaped in a conical trapezoid of 0.7mm in its lower base diameter D, 0.6mm in its upper base diameter d, and 0.5mm in depth, therefore an area ratio of the lower base to the upper one becomes 1.17. An Ni-plated Cu-Zr alloy wire 6 or 0.6mm in diameter is press-fitted into the hole 8. In this kind of connection member, the contact area of the head 3 to the lead wire 6 is enabled to grow large, with its coupling strength increased. Because a plastic deformation part of the press-fit lead wire 6 is pressed against the side of the conical trapezoid, a collar-shaped part 61 is not formed.

Abstract: PURPOSE:To eliminate the uncertainty of a servo system due to a time delay for detection with a simple constitution by performing focus servo by changing a bias control circuit on the basis of an output obtained based on reflected light obtained from an optical pickup device. CONSTITUTION:The surface of a CD 24 is irradiated by a laser beam emitted from a semiconductor laser 21 through a beam splitter (BS) 22 and object lens 23.

Title: Video signal processing device
Inventor: MATSUO TADAAKI
IPC: H04N5/92
Filed: 1984-08-24
Abstract: PURPOSE:To decrease the deterioration of S/N of a video signal due to quantitizing noise by adding a positive polarity synchronizing signal to a video signal and demodulating the video signal having a negative polarity synchronizing signal after applying A/D conversion, signal processing and D/A conversion. CONSTITUTION:A video signal from a terminal 6 is added to a positive polarity synchronizing signal and supplied to an A/D converter 2 by a synchronizing signal adding circuit 1. The A/D converted video signal is processed at a signal processing circuit 3, and after that, the signal is supplied to a D/A converter 4. The D/A converted video signal is reloaded to the video signal having a negative synchronizing signal by a synchronizing signal reloading circuit 5. In such a way, since the video signal to which the positive polarity synchronizing signal is added is A/D converted, resolution can be improved. Thus, the deterioration of S/N of a video signal due to a quantitizing noise can be decreased.

Abstract: PURPOSE:To prevent the unevenness of image density from occurring by making the difference of the sticking amount of toner sticking to the center part and both right and left ends of a developing roller small. CONSTITUTION:A thin layer blade 36 is formed in the shape of a trapezoid having the width of a base end 36a shorter than that of a leading end 36b. By holding the base end 36a by a blade holder 37, the leading end 36b of the blade 36 is pressed on the developing roller 35. Then, sealing members 38 are pressed on both right and left ends 35a of the roller 35 and both right and left ends 36c of the blade 36 so that the member 38 may be superposed thereon to be smaller and smaller as it gets to the base end 36a of the blade 36. Thus, force received by both ends 36c of the blade 36 is made small by the member 38, and the blade 36 is nearly uniformly pressed on the roller 35 so that there is no difference between both ends 36c and the center part.
