Inventor: HAYASHI EIJI
IPC: G12B11/04
Filed: 1993-02-19
Abstract: PURPOSE:To obtain a thin meter with reduced structure parts by attaching revolution angle detector outside of the rotor of an ultrasonic motor. CONSTITUTION:By attaching a revolution angle detector 30 on the periphery of the rotor 11 of ultrasonic meter 10 and rotating the detector 30 together with the revolution of the rotor 11, the revolution angle of the motor 10 is detected. At the detector 30, alternating current voltage Ea to En having phase shifts of 45 degree each are impressed to separated electrodes 33a to 33h constituting the electrode 33 and rotational electric field over 0 to 360 degree is generated. If rotational elecric field is choked with an electrode plate for collection, the electric potential of the rotational electric field propagates to the electrode plate 31. Then, by driving the motor 10, rotor 11 is rotated, the rotation disk 32 constituting the detector 30 rotates and the phase angle of the rotational electric field picked out of the electrode plate 31 varies from 0 to 360 degree. Thus, by detecting the variation of the phase angle and knowing rotation angles of the disk 32 that is, the rotor 11 of the motor 10, the position- measured quantity of electricity can be measured. With this constitution, the ultrasoutic meter thickness can be reduced to approximately 4.8mm.

Abstract: PURPOSE:To enable light transmitted through a photoconductor cable to be properly irradiated to the head skin by constituting a medical appliance from an annular light source member and a cylindrical transparent light irradiation member. CONSTITUTION:When an annular member 5 is connected to a photoconductor cable 1 with a connector 6, light transmitted through said cable 1 is irradiated from the other ends of optical fibers 7 through the connector 6 and each optical fiber 7. On the other hand, a cylindrical member 8 is constituted of a transparent member, and one end face 8a thereof is removably attached to a light radiating surface 5a of the annular light source member 5 and the other end is formed into the form of comb teeth consisting of a plurality of converging portions 8b. Thus, when the face 8a of said member 8 is connected to said surface 5a, the light emitted from said surface 5a is introduced from said face 8a into said member 8 to be radiated from the other end 8b. Hence, when the converging portions 8b are mounted on the head or the like, the light transmitted through said cable 1 can be irradiated directly to the head skin.

Filed: 1980-03-11
Abstract: PURPOSE:To obtain a storage circuit having a small occupied area, by giving a control to the read/write current of the storing transistors forming a flip-flop via a diode that is connected to a collector. CONSTITUTION:The npn type transistors Q1 and Q2 are connected to the loads L1 and L2 comprising the resistances R1 and R2 which are parallel to the diodes respectively of form an FF. The collector of the transistor Q2 is connected to the wiring W5 via the diode D. In the state under which the transistors Q1 and Q2 turn on and off the high and low voltages of the wirings W1 and W2 and then store them, the current flows via W1, Q3 and W3 each to be read out. When the transistors Q1 and Q2 are off and on respectively, the current flows via the load L2 as well as the diode D that connects the wiring W5 and the collector of Q2 that gives a higher potential to W5 than W1. And no current flows to Q4 and W4 to read out the storage. The rewriting of the information is carried out in the same way to reduce the number of controlling transistors and control lines. Thus a storage circuit of a simple constitution can be obtained with a small occupied area.

Abstract: PURPOSE:To enable a different current to be detected with one detection circuit by a method wherein the title excess current detection device is composed of a resistor and a diode which make one detection current flow and an A/D converter which detects the current having flowed to the resistor and the diode. CONSTITUTION:A resistor 5 and a diode 15 which make a detection current flow are connected to a drive circuit 7 of a coil 6. At that time a voltage value to be inputted to an A/D converter 3 is different according to a state of the drive circuit 7 and becomes a specific value at each ON/OFF state. A switching means 4 is generally of an ON state in a printing control state of a printer, which connects a power source to the drive circuit. The voltage value obtained from the A/D converter 3 is converted to a current by a current judge means 1 to detect an overcurrent. That is, the current judge means 1 calculates a voltage value to be inputted to the A/D converter 3, and compares the calculated value with the voltage value inputted actually to the A/D converter 3. Where they do not come to be almost the same value, the drive circuit 7 is judged to be abnormal.
