Title: Valve for low temperature
Inventor: SHIMOMURA HIROAKI
IPC: F16K1/32
Filed: 1989-07-31
Abstract: PURPOSE:To reduce the area of sliding faces constituted of a plug and a guide bush, reduce the shearing force required to break ice, easily break ice, and prevent a pressure rise accident caused by residual gas by providing three or more axial grooves on the plug. CONSTITUTION:Three or more axial grooves 8 are provided on a plug 1, and the Center line of the plug 1 is made coincident with the center line of a valve seat 3. The depth of the grooves 3 is preferably made deep as far as strength allows so that the liquefied moisture does not bury the grooves 8 by freezing. When the plug 1 with the above constitution is used, the moisture liquefied at the initial stage of operation flows down from a guide bush 2, even if freezing occurs on sliding faces of the guide bush 2 and the plug 1, the area applied with the shearing force is small, thus ice can be easily broken. The residual gas is released through grooves 8 after the operation is stopped, thus no pressure rise accident occurs.

Title: Microetching agent for copper and copper alloy
Inventor: MAKI YOSHIAKI
IPC: H05K3/38
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To roughen the surface of copper to have deep recesses excellent in adhesion property to a solder resist and the like by incorporating a copper(II) ion source, an org. acid having a specified acid dissociation const. and a halogen ion source into a microetching agent for copper. SOLUTION: A copper(II) ion source, an org. acid having <5 acid dissociation const. and a halogen ion source are added to a microetching agent which is used to treat the surface of copper and copper alloys. Since the copper(II) ion source is used as an oxidizing agent, the obtd. etching soln. shows a proper etching rate and stably forms deep recesses on the copper surface. As for the copper(II) ion source, for example, copper salt of an org. acid, copper(II) chloride, copper(II) bromide, and copper(II) hydroxide can be used. The org. acid having <5 acid dissociation const. is compounded to dissolve the copper oxidized by the copper(II) ion as well as to control pH, and for example, formic acid, acetic acid, propionic acid, etc., can be used.

Abstract: PURPOSE:To lower an instantaneously consumed current and to decrease a battery capacity so as to attain a cost reduction by allowing >=1 dots to emit light with deviation in timing without allowing these dots to simultaneously emit light at the time of film movement, such as winding or rewinding. CONSTITUTION:A microcomputer 10 determines the moving speed of the film in synchronization with the movement of perforation holes with the winding of the film after a release button from the voltage change of the collector of a phototransistor 9 of a reflection type photointerrupter 1 and calculates the interval time and emission time of the light emission according to this moving speed and the inputted ASA sensitivity to control an LED 3. The microcomputer firsts sets an output terminal at a low level in the time of a section 52 in order to light an LED 20. The computer maintains an output terminal 41 at a low level with a delay by the time of a section 53. Output terminals 42 to 46 are similarly maintained at the low levels, by which the emission timings of LEDs 20 to 26 are shifted.

IPC: H01L27/14
Filed: 1988-08-05
Abstract: PURPOSE:To execute effective confinement of light by forming a striped SiO2 film on a waveguide layer thus forming an optical waveguide having an effective stage difference of refractive index to that of a direction parallel to a boundary face. CONSTITUTION:A ZnS layer functioning as a lower clad layer is formed by an epitaxial growth by an MOCVD method on a GaAs substrate, then an SiO2 mask 5 is deposited by a thermal CVD method. Then, the SiO2 film is patterned and the SiO2 film at the part for forming a waveguide layer is removed. A ZnSe layer for a waveguide layer and a ZnS layer for a clad layer are formed successively by a selective epitaxial growth using the patterned SiO2 film. In this stage, there is no deposit on the masking SiO2 film. For the selective epitaxial growth of ZnS and ZnSe, org. compds. of Zn, S, and Se are used as raw materials, and the pressure is regulated to <=100Torr, the temp. to >=400 deg.C and <=700 deg.C, and a molar ratio of a VI group raw material and a II group to be fed to <=6, by a reduced pressure MOCVD method. Thus, a ZnSe layer for a waveguide layer and ZnS layer for a clad layer are formed. An optical waveguide is completed by removing SiO2 with HF.

Filed: 1988-08-09
Abstract: PURPOSE:To attain parallel A/D conversion with high accuracy by comparing a reference voltage with an analog input voltage with a comparator group and counting its output with a counter circuit. CONSTITUTION:A group of resistors R1...RN-1 to generate a reference voltage group and a group of comparators C1...CN to compare a reference voltage with an analog input voltage are provided on the converter. Then the analog input voltage and a reference voltage divided by the resistors R1...RN-1 are compared by the comparators C1...CN.

Even if there are plural parts with a change in 0, 1 in the output of the comparators to count the outputs of the comparators C1...CN at the adder circuit, the monotony as the AD converter is maintained. Thus, the reference voltage together with an offset voltage of the comparators C1...CN makes the range of input voltage to be distributed uniformly.

Title: Picture data file control system
Inventor: TOHO ATSUSHI
IPC: G06F12/00
Filed: 1989-07-31
Abstract: PURPOSE:To secure the data on pages obtained before occurrence of a fault by providing a page allocation table in order to control a picture data file for each page. CONSTITUTION:The head FAT address is stored in a page allocation table (PAT) store area 4 to the data on each page of a file. A FAT store area 1, a directory store area 2, and the area 4 are set into a main storage (memory) and an auxiliary storage (disk). The contents of these areas 1 - 4 are updated as necessary. Thus an access is possible to a data file via the designation of pages carried out by the PAT when the data file consisting of each page is written into the auxiliary storage. As a result, the data on pages obtained before occurrence of a fault can be secured at restoration of the fault by disusing the data on the pages obtained at occurrence of the fault if a fault occurs during a data file access.
