Filed: 1982-01-21
Abstract: PURPOSE:To make it possible to utilize the circuit even though it has defects without discarding it, by preparing a plurality of circuit blocks with the same function comprising high density active element regions which tend to include serious defects, wiring the selected good circuit so as to contribute the operation, thereby improving the circuit design and the yield rate. CONSTITUTION:In a microcomputer chip in an example in the figure, two ROMs and two ALUs having the same functions, respectively, are prepared. In this constitution, e.g. in the ROMs (A) and (B), the probability of the even either of (A) or (B) does not have the defect is twice the probability of the event the ROM  (A) does not have the defect. Then a plurality of the blocks (e.g. two), which are formed by the high density active elements and have a small occupying area, and whose probability of the event of including the defect is low, are intentionally prepared. A selecting circuit (e.g. a fuse circuit wherein polysilicon is used) is provided for each block. The characteristics of the blocks are checked by the selecting circuits, and the block which does not have the defect is selected. Then the yield rate is improved by twice or more by only increasing a pellet area by 1.5 times.

Title: Ultrasonic vortex flowmeter
Inventor: KASHIMOTO HIROO
IPC: G01F1/32
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic vortex flowmeter capable of enhancing reliability and performing signal processing using two sets of ultrasonic sensors. SOLUTION: A switch mechanism 27 (first and second switches 26a, 26b) is provided for connecting first and second oscillators 16a, 16b selectively to first and second transmitters 13a, 13b. If the first oscillator 16a or second oscillator 16b fails, the switch mechanism 27 is actuated for switching and the oscillator which has not failed is connected to the first and second transmitters 13a, 13b, so that even if either of the first and second transmitters 16a, 16b fails, flow measurements can be made with the other oscillator which has not failed, whereby reliability of the flow measurements can be enhanced. Since the first and second transmitters 13a, 13b are driven by a common oscillator, interference between ultrasonic waves from both transmitters and the resulting beats are avoided. Also, both ultrasonic waves are synthesized without interference and sound pressure becomes higher.

Title: Reproducing device
Inventor: KANEKO HISAHARU
IPC: G11B11/105
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To enable information to be reproduced irrespective of the kind of medium. SOLUTION: To a magnetooptic disk 1, the medium identifying information for identifying the kind of medium is written. A readout circuit 4 reproduces the medium identifying information from the signal obtained by an optical head 3. When the disk 1 is identified to be a super-high-resolution magnetic medium of rear aperture detection(RAD) by the medium identifying information, an initializing electromagnet control circuit 6 impresses an initializing magnetic field on the disk 1 by making a current flow through the electrimagnet 5. When the disk 1 is identified to be a medium which needs no initialization, the control circuit 6 supplies no current to the electromagnet 5. By this, the disk 1 is reproduced in the condition in which no initializing magnetic field is impressed.

Title: Machine tool
Inventor: YONEYAMA TERUAKI
IPC: B23Q3/155
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To rationally realize tool gripping force of a collet by providing a tool unclamping means for releasing gripping force for a tool by pressing the collet forward in the axial direction of a main shaft by making use of pressure of coolant. SOLUTION: Clamping of a small-diameter tool is performed by using stable energizing force of a bellevill spring 51. In unclamping of the small-diameter tool, when coolant (normally, gas such as compressed air) to serve as an operating medium is fed from a coolant supplying source, it enters a cylinder chamber part 43b on the back pressure side of a piston member 47 from an introducing pipe part through a draw bar and a diameter extending part, so as to advance the piston member 47 while competing with the bevel spring 51. Therefore, a part whose diameter is contracted of a spring collet 31 is elastically returned to the original diameter, and clamping of the small-diameter tool is released.

Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To restart a torque control without relying on the judgment and operation of a train driver by providing an induction motor state detecting part which inputs a primary angular frequency and, if its absolute value is equal to or lower than a preset primary angular frequency, flags a control switching at regular intervals of time, and by providing a torque controlling part which restarts a torque control. SOLUTION: A torque controlling part 11 inputs a current I, a rotational angular frequency ω m, a torque command T*, an input voltage VDC, an operation command S and a control switching flag F. If the control switching flag F is flagged in a state that the operation command S is emitted, the controlling part 11 interrupts the torque control and restarts it after performing a starting mode. A speed computing element 13 inputs the current I and voltage V of an induction motor 12 and computes a primary angular frequency ω, a slip angular frequency and the rotational angular frequency ωm. An IM state detecting part 14 inputs the primary angular frequency ω.  If its absolute value is equal to or lower than a preset primary angular frequency or lower, the detecting part 14 raises and outputs the control switching flag F at intervals of a preset time, thereby enabling the torque control to be restarted without relying on the judgment and operation of a train driver.

IPC: G11B5/84
Filed: 1990-01-18
Abstract: PURPOSE:To obtain a good magnetic layer by smoothening a nonmagnetic supporting body, forming a dummy layer thereon, smoothening its surface and then forming a magnetic layer thereon. CONSTITUTION:A dummy layer 11 is formed on a nonmagnetic supporting body 2. This dummy layer essentially comprises a polymer resin which can be easily treated for smoothening compared to the supporting body 2 or this polymer resin and nonmagnetic particles. The dummy layer 11 is subjected to calendering after smoothening treatment is performed on the surface of the layer 11, on which a magnetic layer 12 is formed. Since the magnetic layer 12 is applied on the dummy layer 11 having good surface property, the magnetic layer 12 can be also made to have good surface property even if the surface property of the supporting body 2 is bad. Thereby, the magnetic layer having high reproduction output, low tape noise and good surface smoothness can be formed as a thin layer on a cheap supporting body 2 having rather bad surface smoothness.

CONSTITUTION:Chrominance signals PB17 and PR18, to which A/D conversion is executed with the double sampling frequency, are inputted to the input terminal of a switch 3. The switch 3 changes over the inputs according to a PB/PR control signal 29. For example, when the PB/PR control signal 29 is set at a Hi level, the chrominance signal PB17 is selected and when the signal 29 is set at a Lo level, the chrominance signal PR18 is selected. Next, a chrominance signal 19 is passed through a vertical filter 4 as the preprocessing of line sequentiality and converted to a chrominance signal 20 while limiting the band. Then, the chrominance signal 20 is inputted to latches 5, 6 and 7 for the line sequentiality. As a result, a linear sequential signal suitably switching chrominance signals PB' and PR' can be led out from the latches 5, 6 and 7 by switching the latches and clocks A and B.
