Filed: 1989-07-24
Abstract: PURPOSE:To decrease the effect of the operating speed and to facilitate the check and revision by using a comparator in a semiconductor circuit employing a P-channel MOS transistor(TR) and an N-channel MOS TR and using two transfer gates so as to select between two different reference voltages depending on low or high level being an output logical level of the comparator. CONSTITUTION:Transfer gates 2,3 are provided and V1, V2 are different refer ence voltages. With an output of a comparator 1 at a low level, the reference voltage of the comparator 1 is V1 and with an output of the comparator 1 at a high level, the reference voltage of the comparator 1 is V2. The two differ ent reference voltages are switched by the transfer gates and the load of the comparator is only the gate of the next stage, the effect on the operating speed is less and the low level input voltage, the high level input voltage and the hysteresis width depend only on the two reference voltages.

Title: Production of welded wide flange shape
Inventor: IMAMURA MASAKI
IPC: B23K13/08
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain a welded wide flange shape having sufficient welding strength without buckling in a web part by setting a pressurizing quantity at zero prior to the start of welding, controlling the pressurizing quantity under the pressure from a pressure detector after the start of welding and regulating energing time at the time of stopping and starting material passage at the time of cutting. SOLUTION: Upper and lower pressurizing rolls 9 are so set that the gap therebetween attains the sum of the width of a coil w for the web and upper and lower flange thicknesses. Welding is started by supplying welding electric power to a high-frequency resistance welding machine and simultaneously the material passage is started. The welding electric power is increased until the pressurizing quantity attains the prescribed quantity within the allowance range of the size of the slit part of metal molds by using a pressure detector 14 in such a manner that the web w does not exceed the buckling threshold during the material passage. The material passage is once stopped after the material is passed several meters and the welding electric power is applied for at least 1.0 sec after the stop of the material passage.  The cut part is mended by fusion cutting the unwelded part and defective N size part at the front end after the stop of the material passage. The welding is thereafter started again by passing the material. At this time, the material passage is started upon lapse of at least 0.4 sec after the supply of the welding electric power.

Title: Superconducting coil
Inventor: OKA KOICHI
IPC: G01R33/12
Filed: 1991-07-31
Abstract: PURPOSE:To adjust an internal flux distribution of a superconducting coil operating in a permanent current mode by short-circuiting coil ends. CONSTITUTION:Two flux adjusting coils 21,22 arc fitted onto an outer periphery of a superconducting coil 1 and they are placed separately from each other along a center axis 30, whereby a flux density distribution with a center curve slacking where the center part is low and both sides are high is generated. Since superconducting coil current varies to prevent generation of flux density, a peak of the flux density distribution is mainly offset, resulting in incomplete offset of the center magnetic field. Therefore the residual magnetic field is utilized for adjusting an internal magnetic field of the superconducting coil.

Title: Feeding image receiving sheet
Inventor: NAGATA SHOICHI
IPC: B65H3/46
Filed: 1987-07-30
Abstract: PURPOSE:To protect a coated surface in feeding image receiving sheets in a copier using photosensitive and pressure sensitive type image forming material by applying a feeding roller to the base sheet surface of an image receiving sheet. CONSTITUTION:An image receiving sheet 5 is contained in a feeder cassette 51 with the surface of coating development material down, and fed by means of a feeder roller 52.

Title: Pattern checking apparatus
Inventor: ICHIKAWA MASAMI
IPC: H05K3/00
Filed: 1988-08-01
Abstract: PURPOSE:To make it possible to perform accurate checking even if an object to be checked is expanded and contracted by using intervals between marks for detecting the amounts of expansion and contraction which are formed on the object to be checked along the relative moving direction of an image sensor as mark data, and comparing the data with standard mark data. CONSTITUTION:A printed board 10 is relatively moved with respect to an image sensor 21 with a moving part 41. The images of patterns on the board 10 are sequentially picked up with the sensor 21. A mark detecting sensor 31 detects expanded/contracted-amount detecting marks 12 as mark data. In a control part 24, standard patterns which are stored before-hand are compared on the patterns which are formed on the object to be checked. It is judged whether or not defects are present. In an expanded/contracted-amount detecting part 32, standard mark data which are stored beforehand are compared with the detected mark data. Thus the amounts of the expansion and the contraction of the board 10 are detected. When the board 10 is expanded and contracted from environmental conditions, the intervals between the mark data detected with the sensor 31 are different from those of the reference mark data. A signal for changing the moving speed is sent out so that the intervals become equal.
