Title: Stepping motor-driving method and device
Inventor: MIZUNO HIROYUKI
IPC: H02P8/12
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To eliminate rotation irregularity by synchronizing a coil winding current control PWM operation with a step-advance pulse when driving a stepping motor. SOLUTION: In the drive circuit, rotary speed irregularity is small when PWM synchronization is half as compared with a step-advance pulse period, so that a total division ratio when the number of micro step divisions is equal to four is set to eight that is obtained by multiplying the number of divisions by a ratio 2 of the above conditions. Then, the period of a signal PLS is set to tPLS, a rising edge is generated in a signal PLS in the case of a step of 1.25 for updating ON width, a PWM operation is generated in synchronization with a falling edge, and the period reaches tPLS/2. Also, a switch element P1 is turned on, and the ON period reaches tPLS/8 since it is equal to 25% of the PWM period. Then, a rising edge is generated for reaching ON width, and P1 is turned on. However, the ON period reaches 2tPLS/8 since it is equal to 50% of the PWM period.  In the similar manner, each step period always becomes constant as in tPLS, thus suppressing the irregularity in rotary speed.

Title: Protection circuit of flyback transformer
Inventor: WATANUKI SEIJI
IPC: H04N3/18
Filed: 1983-11-18
Abstract: PURPOSE:To prevent chain destruction due to layer shorting by detecting a pulse which is generated in the time between the period when a damper diode is being on during horizontal scanning and the period when a horizontal output transistor turns on next. CONSTITUTION:A signal from a horizontal oscillator circuit 1 operates a horizontal output circuit through a horizontal drive transformer 3, and supplies a high voltage to a cathode-ray tube anode through a coil S2 of a flyback transformer 9. When layer shorting occurs in the coil S2 of the transformer 9, the period when a damper diode 5 of the horizontal output circuit is being on becomes extremely shorter, and at the time between the period when the diode 5 is being on and the period when the following horizontal output transistor 4 turns on, a pulse voltage is generated in a resonance capacitor 12. The pusle voltage operates a horizontal oscillation stop circuit 118, and oscillation of the circuit 1 is stopped.

Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce weight, to facilitate handling and storage, and to improve strength and abrasion resistance of the tool main body surface by covering the surface of an aluminum-made tool main body with a nickel phosphorus alloy. SOLUTION: A material of a tool main body 2 is aluminum, and in the surface, a covering layer 18 of a nickel phosphorus alloy covers a recessed groove 4 before installing a cartridge 5 by chemical plating, but a screw hole of an adjusting bolt and the bolt hole 12 inside of a fastening bolt 6 are not covered.

Abstract: PURPOSE:To attain the automatic control of a solar battery to the maximum power point regardless of the characteristics of the solar battery, by detecting the voltage and the current of a solar battery and setting the reference voltage value to obtain the maximum power point of the solar battery together with monitor given to the variations of both the electric power and the voltage. CONSTITUTION:The maximum power point M is set when the luminous intensity and the temperature are constant, and a point N shows the voltage value of a solar battery. In an early tracking stage for the maximum power point, the reference voltage value VPV* is set so as to equal to the no-load voltage V0 shown in the figure. Then the VPV* is reduced in a fixed with in a prescribed sampling period, and the electric power increases toward A and then moves toward C after exceeding the point M. Then the VPV* is delivered in the direction where it is increased in the fixed width after detecting that the electric power is set toward C. The electric power reaches the direction B when the VPV* is continuously increased. Then the VPV* is reduced again after detecting that the electric power shifted toward B. When these actions are repeated, the VPV* has the reciprocating shifts at a place near the point M.

Abstract: PURPOSE:To provide a sufficiently large cathode area without enlarging the outside dia. of cathode by forming a cold cathode in such an arrangement that a metal sheet provided A with discharging windows is wound in spirally. CONSTITUTION:When a lightup voltage is impressed between two lead-in wires 2, 2, a discharge current flows between two cold cathodes. At this time, the cold cathodes are heated with flow-in and flowout of the discharge current, and an emitter is activated to emit electrons. With this heat the cold cathodes 3 undergo thermal deformation during service, and the surfaces 34, 34 of a sheet 3 move apart or approaching, or contact each other. However, the discharge flows in or out through discharging windows 32, 32... of sheet 31, and discharge is made in good performance at the rear side 34 of the sheet 31, and the discharging is not hindered even though the gap between the surface 34, 34 is narrow. Because of this provision of discharging windows 32, 32... the cold cathode 3 does not substantially exhibit drop of the effective area for discharging despite decrease in the actual area. The cold cathode 3 can be embodied small size despite its larger output because of the spiral form.
