Title: Reader/writer for memory unit
Inventor: HAYASHI HIDENORI
IPC: B42D15/10
Filed: 1991-02-13
Abstract: PURPOSE:To exactly judge the quality of a backup power source by investigating it by actually reading/writing data whether the backup power source for memory hold built in a memory unit is normally operated or not. CONSTITUTION:A specified data is written to the specified address of a memory unit 7 loaded to an independently portable package in the state of impressing a power source 5 for access. Afterwards, the power source 5 for access is turned off only for fixed time and next, in the state of turning it on again, the data at the specified address is read out. Then, it is judged whether the data is correct or not. When the backup power source of the memory unit 7 is normal, even in the case of turning the power source 5 for access off for fixed time, the specified data written just before the OFF is correctly read out just after the OFF. When the backup power source is consumed, the specified data is lost when the power source 5 for access is turned off, and the data read out just after the OFF is wrong.

Title: Stepper
Inventor: YOSHITAKE YASUHIRO
IPC: G02B5/32
Filed: 1992-02-05
Abstract: PURPOSE:To increase the resolution of an alignment pattern for a very accurate alignment by illuminating an alignment mark on a projection substrate with light of a wide wavelength width through a projection lens and by correcting a chromatic aberration caused by the projection lens at the time of detecting the alignment mark. CONSTITUTION:Light of a wide wavelength width which is emitted from an illumination light source 11 is led through an optical fiber 12 to illuminate an alignment mark 31 on a wafer 3 through an achromatic lens 13, a beam splitter 14, a bending mirror 15 and a reduction projection lens 2. An image of the alignment mark 31 is formed on an image sensing element 5 by means of an achromatic lens 41 and a holographic lens 42. The holographic lens 42 corrects a chromatic aberration of the reduction projection lens 2. By this method, the distance between the wafer and the image sensing surface can be shortened and thereby mounting can be done easily and the resolution as a detecting system can also be enhanced and eventually a very accurate alignment is available.

Abstract: PURPOSE:To make it possible to perform smooth blasting even when the blasting quantity is large at the time of opening an upper discharge port and to suppress the generation of noise by making a flow passage from a blower in the direction of an upper discharge port substantially rectilinear. CONSTITUTION:When the room temperature rises up to a predetermined value or more, this temperature rise is detected by a room temperature detecting part Rt, and transmits a detection signal to control means to normally rotate a geared motor 22. Then, switching from a front discharge port 5 to an upper discharge port 4 is carried out. Upon this occasion, the convection of indoor air is promoted, and warm air staying at the upper part is agitated to particularly promote unification of indoor temperature distribution. In addition, the orientation direction of a warm air flow passage 6b with respect to the upper discharge part 4 is made rectilinear, a small flow pat resistance may be enough. Therefore, even when a large air amount is discharged through the upper discharge port 4, smooth blasting becomes possible and generation of noise can be effectively suppressed.

IPC: G01N21/51
Filed: 1989-01-30
Abstract: PURPOSE:To measure the small turbidity of pure water with high sensitivity by determining the turbidity from the intensity ratios of the scattered light and reference light to incident light. CONSTITUTION:The light from a light source 13 is condensed to form the image of the light source 13 on a circular slit S.

Next, the mold parts fed at the pitch to a position 4c receive the jetting injection from a lower part by a high pressure water nozzle 5b'' whereby small burrs and foreign substances at the lower surface side are all removed, thus deburring is over. Thus when these high pressure water nozzles 5a and 5b are installed in both upper and lower parts of these positions 4b and 4c of electronic parts, there is unnecessary to turn over top and bottom of each of mold parts in the midway of pitch-feed the mold part at the position 4b up to the position 4c.

Title: Manufacture of thermal head
Inventor: ARAKI KENICHI
IPC: B41J2/335
Filed: 1984-02-07
Abstract: PURPOSE:To prevent a sharp oxidization at the contact part between an Au layer and Zr-N thin film by keeping this part from directly contacting an oxidizing atmosphere in a thermal treatment for thermal head having the Zr-N thin film as a heat generating body and the Au layer as a conductive layer. CONSTITUTION:A high temperature thermal treatment is implemented in such a manner that at least the direct contact part between an Au layer 4 and a Zr-N resistor thin film 2 is kept from directly contacting an oxidizing atmosphere. In order words, the atmosphere at the high temperature thermal treatment is made non-oxidizing, for example, vacuum, an inert gas such as Ar or a reducing gas such as H2. With such an arrangement, since the contact part between the Au layer 4 and the Zr-N thin layer 2 will not contact the oxidizing atmosphere, no sharp oxidization occurs at this part at all during the thermal treatment thereby eliminating poor conduction as in the past. This enables a stable manufacture of a thermal head using the Zr-N thin film as a resistor, namely, a heat generating body with a high yield.

Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a solenoid valve which can properly keep an air gap in a usage state without controlling the amount of pressing-in with high accuracy and monitoring a pressing-in load. SOLUTION: A solenoid valve 10 has a seat valve 34 pressed into a guide block 14 and the seat valve 34 is tightly integrally fixed to the guide block 14 in a state in which the crimping part 18 of the guide block 14 is crimped and pressed on the flange part 36.

Therefore, an air gap ΔG is not changed and the characteristics of the valve can be prevented from being changed.

Abstract: PURPOSE:To minimize the number of shift registers requiring high speed operation while the transfer speed of recording information is brought into a low speed by allowing each drive means to shift a recording time signal in the drive method and giving a recording signal to a drive means according to the shift timing of the recording time signal.

A shift register SHRn has 32 bits and a recording time signal RTS (high level) is inputted to the head bit. Then the top high level is shifted sequentially according to the timing clock RTS. A Dn drives a heat resistive element of an HRn corresponding to a location of high level in the SHRn. Thus, when the Dn is in on-state by an output of an Ln at the point of time, the heat resistive element is energized.
