Abstract: PURPOSE:To secure the accurate driving of a stepping motor all the time by detecting a voltage between a main driving pulse and a correcting driving pulse. CONSTITUTION:A charging circuit consists of a capacitor 4 which is charged by a solar cell 1, a capacitor 2 which has less capacity than the capacitor 4, an integrated circuit 3, etc. The circuit 3 consists of a voltage detecting circuits 17 which detects terminal voltages across the capacitors 2 and 4, a voltage detection timing generating circuit 16 which determines the detection timing of the circuit 17, a driving pulse generating circuit 18 which drives the stepping motor, etc. Then, the circuit 18 generates main driving pulses 10 with relative narrow pulse width and correcting driving pulses 11 with relative wide pulse width and the timing of voltage detection pulses 13 by the circuit 17 is set between the pulses 10 and 11. Consequently, the voltage recovers sufficiently before the pulse 11 rise, so the stepping motor is driven normally with the pulses 11.

Filed: 1986-04-09
Abstract: PURPOSE:To prevent a dial signal from being outputted from a power failure dial circuit at power application by supplying a signal controlling always turning on a switching circuit to the 2nd dial circuit at power application. CONSTITUTION:A dial signal generating circuit 9 receives a current from a constant current circuit 10 and is brought into the operating state at the talking enable state, a signal is outputted to a terminal 9a to turn on the switching circuit 12. On the other hand, since the same potential as that of the other power input terminal 9c is applied to a control input terminal 9b by a photocoupler 13 always turned on, the circuit 9 is inactivated and no dial signal generating output is sent even with the operation of a keyboard 8. When the talking is finished and a hook switch 15 is opened it is detected by,e. g., the master equipment, its information is supplied to a control circuit 5 and the relay A is driven, then the state is brought into the preceding state.

Filed: 1988-04-01
Abstract: PURPOSE:To prevent the disturbance at an interface by allowing a liquid to quietly flow along the inner surface of a test tube, by modifying the surface of the test tube made of polyester for a centrifugal separator by applying hydrolysis treatment thereto to impart hydrophilicity thereto. CONSTITUTION:In a lightweight test tube for a centrifugal separator made of polyester excellent in impact resistance, the test tube is treated with an aqueous solution of alkali metal hydroxide such as lithium hydroxide or sodium hydroxide. Whereupon, alkali metal hydroxide acts on the carbonyl group of polyester to out the polymer chain thereof to generate hydrolysis bringing the carbonyl group to a carboxyl group. By this surface modification of the test tube, when a liquid is allowed to flow in the test tube, said liquid can be allowed to quietly flow without forming a liquid droplet by utilizing the inner surface of the test tube and an interface is not disturbed.

Title: Position sensor
Inventor: KURAISON TORONNAMUCHIYAI
IPC: G01S3/781
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a position sensor which facilitates position computations. SOLUTION: The light-reception currents of photodiodes D1, D2, D3 arranged at equal distances to one another within a length L are converted into voltages by resistances R. The voltage obtained are output to MOSFETs M (M1, M2, M3), which are connected to one another via the resistances, and to MOSFETs N (N1, N2, N3) which are connected to one another not via the resistances. Outputs of the MOSFETs M are expressed as A-outputs and those of the MOSFETs N are expressed as B-outputs. Since the MOSFETs M vary in amplification factor depending on their positions, an output from an A-output terminal becomes proportional to the the light receiving position. The amplitude of the MOSFETs N do not vary with the light receiving position, so an output from a B-output terminal is constant regardless of change in the light receiving position.  Therefore, calculation of the light receiving position using the A-and B- outputs can be achieved only through subtration, resulting in increased computing speed.
