Title: Storage device
Inventor: KAWAI HIDEKI
IPC: G11C11/401
Filed: 1989-01-12
Abstract: PURPOSE:To obtain a data input/output bit constitution of an arbitrary combination by providing a register for storing selective information corresponding to each terminal in order to designate the data input/output bit constitution. CONSTITUTION:Switching of a data input bit constitution is executed by allowing registers 21, 22 and 23 to store selective information of data input terminals 11, 12 and 13. Switching of a data output bit constitution is executed by allowing registers 91, 92 and 93 to store selective information of data output terminals 101, 102 and 103. In such a way, by setting in advance combined information of a data input/output bit constitution to the register, and controlling independently a data write circuit part and a data read-out circuit part, respectively by its information, it is possible to cope with an arbitrary bit constitution.

Title: Dc motor drive circuit
Inventor: YAGUCHI OSAMU
IPC: H02P7/29
Filed: 1990-01-12
Abstract: PURPOSE:To widen variable range of locking torque by varying the magnitude of a set voltage and the period of an interruption pulse for periodically turning OFF a transistor which is turned ON based on the comparison result between an electromotive force induced at a terminal and the set voltage. CONSTITUTION:A DC motor 1 is rotated with an external force to induve an electromotive force VM which drops from a DC voltage +Vc. When the voltage VM drops below a set voltage V2 determined by resistors R1, R2 and a variable resistor VR1, a comparator 3 pulls the output voltage Vo from L to H. Assuming the output voltage VN from a saw-tooth forming circuit 12 is L and the output P2 from a pulse forming circuit 11 is H, the voltage Vo and the output P2 go H to turn an AND gate 4 ON thus turning an FET 2 ON and rotating the motor 1. A capacitor C1 is charged to increase the voltage VN thus inverting the output P2 to L through comparators 7, 8. The variable resistor VR1 for forming the set voltage V2 varies the outputs from the comparators 3, 7 in same direction. Consequently, the lock torque of the motor 1 is controlled over a wide range.

Abstract: A coupling apparatus for a length measuring instrument is disclosed. The length measuring instrument includes a scale, which defines a division, and a scanning unit. The scale is connected to a first object and the scanning unit is connected to a second object movable relative to the first.

Title: Flow speed measuring method
Inventor: SHIMIZU TAKEHIRO
IPC: G01S11/00
Filed: 1979-01-23
Abstract: PURPOSE:To make it possible to measure flow speed with a sensor which is small- size and has no movable part, by detecting the acoustic wave, which the acoustic wave generator provided in a fluid pipe generates, by receivers in the upper stream and the lower stream of flow and by measuring the arrival time difference between both receivers. CONSTITUTION:Ultrasonic wave generator A is fitted into pipe P where fluid flows, and receivers B and C are arranged in the upper stream and the lower stream, thereby measuring the arrival time difference between both receiving waves. When the flow speed of fluid and the sound speed are denoted as v(m/s) and c(m/s) respectively and distances and angles are expressed with l1, l2, theta1, and theta2 as shown in the figure, arrival time difference dt of the acoustic wave between receivers B and C is expressed by dt=[c(l1 sin theta2-l2 sintheta1)+v(l1+ l2)]/c<2> sintheta1 sintheta2. Further, if l1=l2=l and theta1=theta2=theta are made true, dt=2lv/c<2> sin<2>theta is true, so that flow speed v can be measured by measuring time difference dt as the above.

IPC: H02K7/08
Filed: 1978-01-21
Abstract: PURPOSE:To let desired light deflection to be effected highly accurately with a simple and small construction by balancing the rotating torque produced by a print disc and magnetic fields and the torque of a control spring produced thereby. CONSTITUTION:When a signal current is supplied between electrodes 22, 23 via amplifier 28, rotating torque is generated in the portion of the conductive pieces 9 provided radially to a print disc 4 and a scanning mirror 3 is rotated by way of a hollow shaft 1 to which the disc 4 is held by fixed. This rotation stops at the point when the rotating torque produced in the print disc 4 coincides with the torsional torque produced in a control spring 26 by the rotation of the hollow shaft 1. Hence, if AC or signal current of square wave or saw tooth wave is supplied between the electrodes 22, 23, the print disc 4 turns continuously in both directions within the range of the specified angle and the light beam scanning by the scanning mirror 3 is accomplished.

Title: Off-shore working platform
Inventor: MATSUMAE HIROSHI
IPC: E02B17/02
Filed: 1982-01-18
Abstract: PURPOSE:To reduce rolling and pitching due to waves and to enable securing of an off-shore working platform, by a method wherein spads pivotally secured forming a pair, to the sides of a burge through the medium of horizontal shafts, are lowered by means of a wire, and tips axles at tips thereof are inserted into the bottom of the sea. CONSTITUTION:Spads 8 are coupled to a burge 10 through tranions 9 having a horizontal shaft, and are hung down by means of wires 12 from a gantry 11 on the burge. Securing of an off-shore working platform is such that the spads 8 are lowered by unwinding the wires 12 by means of a winch, and the point axles 13 thereof are inserted into the bottom of the sea. A rolling and a pitching moment, applied to the burge 10 due to waves, are absorbed by a change in a point reaction 15 of the inclining spad 8 and the tension of the wire, and the burge 10 is prevented from inclining. The spads 8 are pivotally secured, forming a pair, to the sides of the burge 10, and this eliminates the need for an elevating device necessary to a vertical spad, which results in preventing the production of a bending moment.

Abstract: PURPOSE:To enhance reliability by preventing the erroneous judgement of lead inferiority by placing a lead on an inspection stand so as to turn the same upwardly and irradiating the tip part of the lead with light to take the image of the reflected light from said tip part. CONSTITUTION:An electronic component 1 is placed on a sample stand 7 so that the tips of bent leads 2 are turned upwardly and the tips of the leads are irradiated with the light from the fiber illumination light source 8 arranged above the electronic part 1 in a vertical direction and the reflected lights therefrom are photographed with a CCD (image pickup element) camera 6 to obtain an image whose surface vertical to the optical axis of the light source 8 is white. On the basis of the image wherein a white and black binarized level is cleared, the bending of the leads 2 or the lack of the number of the leads 2 is inspected. In a method wherein the bent leads 2 are placed on the inspection stand downwardly and photographed from the lateral direction thereof, the leads 2 are bent in a light path direction and, when the leads 2 are not levitated from the inspection stand 5, the inferiority of the leads 2 can not be discovered.

Abstract: PURPOSE:To increase the anti-blooming magnification ratio without changing the ratio between a photodetecting period and an adverse transfer period, by defining an operation where the electric charge stored to a photodetecting element is transferred to a vertical register and reset as a cycle, and repeating this cycle. CONSTITUTION:Vertical transfer electrodes P1-P4 extending horizontally are formed on the surface of a semiconductor substrate 1 via an insulated film 4. Then transfer control signals phi1-phi4 which are applied to electrodes P1-P4 are all set at the 2nd high voltage Vh2 in a reception mode A. While the signals phi1-phi4 vary between the medium voltage Vm and the low voltage Vl in an adverse transfer mode. The signals phi2 and phi4 are kept at Vl in a read-out state C together with signals phi1 and phi3 increased up to Vh1. Then signals phi2 and phi4 are set at Vl in a reset state E after the forward transfer, and signals phi1 and phi3 are changed to Vh1 from Vm. Then the electric charge stored to a photodetecting element S is transferred to a vertical register 3 and reset. This operation is defined as a cycle and repeated to increase the anti-blooming magnification ratio.
