Patent JP-S586123-A (JP)
Title: Manufacture of semiconductor crystal
Inventor: TANNO YUKINOBU
IPC: H01L21/322
Filed: 1981-07-02
Abstract: PURPOSE:To make surface defect density at the valve two figures or less as compared with a conventional mechanical distortion method by a method wherein low-quality Si single crystal is adhered to the rear of a substrate and the thermal oxidation is applied to the substrate at high temperatures and displacement and a laminated defect are mainly formed on the rear of the substrate with high density. CONSTITUTION:In Si vapor growth, low quality Si single crystal having considerable defect density is grown on the rear of a substrate with 0.5-2.5mum and at 970 deg.C or above and the substrate is oxidized to perform Si vapor growth. This adheres low- quality Si single crystal on the rear of the substrate and applies thermal oxidation to the substrate at high temperature to mainly form displacement and a laminated defect on the rear of the substrate with high density and an Si epitaxial substrate having no surface defect can be obtained as gettering sink. At that time, displacement is mainly induced into the rear of the substrate with high density by substrate oxidation and a defect recognized on the epitaxial surface is used as a microdepotis without an oxidized induction defect and the defect density on the epitaxial surface is formed to be 0-100/cm<2> by using the high density defect included in a single crystal film as gettering sink.

IPC: B29C65/02
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent a metal net from being oxidized by a method wherein nitrogen gas is allowed to flow in a cavity part formed by a body and a cover and air is replaced with nitrogen in a method for preparing of a strainer wherein the metal net is placed between the peripheral edges of the body and the cover made of a resin and forming a tray-like shape and the metal net is heated with high frequency electric current to fuse them. SOLUTION: A metal net 3 is placed between a body 1 and a cover 2 both made of a resin and with a tray-like shape and they are pressed by fixtures 7 and 8 and a high frequency electric current is applied on an electrode 12 to generate heat in the metal net 3 and to fuse flange parts 1a and 2a of the body 1 and the cover and the peripheral edge part of the metal net 3 is embedded and sticked. In this case, nitrogen gas is made to flow into a cavity part formed by the body 1 and the cover 2 from the opening 4 of the body and is replaced with air.

Title: Coil driving circuit
Inventor: KAWASHIMA TETSUJI
IPC: G11B11/105
Filed: 1992-03-30
Abstract: PURPOSE:To improve switching characteristics of a driving circuit for a magnetic modulation coil and to obtain effective magnetic force. CONSTITUTION:For instance, when a transistor 6 is turned into the opening state from the conducting state, a collector current of the transistor 6 does not flow. Then, a collector current of the transistor 6 to flow into the coil 11 does not flow either. However, when the current flowing into the coil 11 is changed, counter-electromotive force is generated by the coil 11 in order to cancel this change. In other words, since the direction of decreasing the collector current of the transistor 6 to flow into the coil 11 is the direction A (as shown by an arrow A in the figure), the counter-electromotive force is generated by the coil 11 in the direction B (as shown by an arrow B in the figure). Since the current to flow into the coil 11 is governed by the coil to flow at a constant rate by this counter-electromotive force, when the transistor 6 is turned into the opening state from the conducting state, a transistor 7 under the opening state is instantaneously turned into the conducting state, so that excitation current is instantaneously allowed to flow into coils 8 and 9.

Abstract: PURPOSE:To prevent an output of a picture element at an end part from increasing and the resolution from lowering by a method wherein a part between the end part in a picture-element arrangement direction and the picture element which is nearest to this end part is covered with a light-shielding layer. CONSTITUTION:Picture-element diffusion layers 2 are formed in a semiconductor substrate 1; light-shielding Al layers 4 are formed via an intermediate insulating layer 3; furthermore, a protective layer 5 is formed. The Al layer 4 near an end face 6 is formed in such a way that it completely covers a part between the end face 6 and a picture element 7 which is nearest to the edge face. Accordingly, the light does not reach the inside of the substrate at the end face, the resolution is not lowered, and an output from the picture element 7 at the end face and from another picture element 8 is not increased. The light-shielding layers may be composed of a material other than Al which can be applied to an image sensor chip such as a CCD, a MOS type chip or the like.

Title: Automatic horizontal hold adjusting circuit
Inventor: EMORI TAKEO
IPC: H04N5/12
Filed: 1984-05-23
Abstract: PURPOSE:To make adjustment of the horizontal synchronizing phase unnecessary by constituting a circuit of two kinds of horizontal synchronizing signal separator and phase detector and three kinds of horizontal synchronizing counter and detecting the phase shift between an input video signal and an input synchronizing signal to correct automatically the phase. CONSTITUTION:The phase difference between synchronizing signals from horizontal synchronizing signal separators 4 and 20 is detected by a phase detector 21 [figure (f)]. This phase difference signal is counted by a horizontal synchronizing counter 23 as shown by A only when this signal is in the high level [figure (g)]. When phases of horizontal synchronizing signals coincide with each other, a phase detector 22 generates a pulse to reset the output of the counter 23. The output of the detector 22 is in the high level because of disaccord [figure (h)]. Set offset data from a terminal 25 is added to data obtained in the counter 23 by an adder 24; and when this data is loaded at a point C by loading it to a horizontal synchronizing counter 6, horizontal synchronizing pulses coinciding with the horizontal synchronizing signal of the input signal are obtained from a point D.

The frame memory 6 dividedly stores the pixel data in respective bit figures in the frame unit. The sum-of-products calculating means 8 reads out the stored set of the pixel data by each bit figure and sums the products thereof to form the column signal components corresponding to the respective bit figures of the sum of products. The horizontal driver 5 impresses the column signals arranged with the column signal components of the bit figures of pulse modulation and the column signal components of the bit figures of frame thinning modulation within one selection period to the column electrode group 3. A memory control means 10 controls writing of the pixel data in the frame memory 6.

IPC: G06F17/21
Filed: 1995-04-05
Abstract: PURPOSE: To lighten the load of retrieval and decision processing by making it easy to select a necessary document out of retrieval results and eliminating the need to classify terms. CONSTITUTION: An input document α as a routine document is decomposed into plural constituent terms, which are set as reference terms γ. Words similar to standard words matching the reference terms γ are stored in a similar word storage area βtogether with similarities by referring to a term dictionary (f). The similar words in this area are rearranged to obtain words similar to the reference terms γ, and those similar words are set as document retrieval reference terms. As for a document data base (g) where similar documents are stored and a retrieval area is set, a document having terms similar to the terms for document retrieval is stored as a similar document in a similar document storage area ε.  The similar documents in this area are rearranged to find the similarities between the input document and similar documents and store them in the similar document storage area ε, and a similar document corresponding to the input document α is outputted.
