Abstract: PURPOSE:To prevent the scattering of powder ink by arranging an electrode between a means selectively bonding the powder ink to an ink sheet and a means fixing the powder ink under heating to form the ink sheet in close vicinity to the rear of the ink sheet. CONSTITUTION:Ink is transferred to a recording medium 7 by a thermal head 5 to form an image and the transfer part 8 and residual part 9 of the ink layer are formed on the ink sheet 1 and the ink sheet 1 is fed to a regeneration part. Powder ink 12 is supplied to the ink sheet 1 in such a state that bias voltage is applied across an opposed electrode 11 and a conductive sleeve 13 from a power supply 14. The powder ink 12 coming into contact with the transfer part 8 of the ink layer of the ink sheet 1 is bonded to an insulating support 2 by the bias voltage acting on the ink layer and the electrostatic force due to the injection of charge. The powder ink 12 coming into contact with the residual part 9 of the ink layer of the ink sheet and the powder ink bonded to the insulating support 2 is not bonded because charges escape. Only the transfer part of the ink layer of the ink sheet can be replenished with the powder ink and the ink sheet is regenerated.

Abstract: PROBLEM TO BE SOLVED: To employ a Schmitt trigger system for an inverter for amplifying the resonance frequency of a crystal vibrator, and to make it possible to supply a noise-free stable clock and enable self-oscillation by forming a logic block of a 1st and a 2nd inverter and an output selecting means. SOLUTION: The input A of the 1st and 2nd inverters 6 and 7 is connected to one electrode of an input stabilized capacitor 3 whose counter electrode is grounded, the crystal vibrator 5, and one terminal of a feedback resistance 2, and the output Y of an output selecting means 20 is connected to one electrode of an output stabilized capacitor 4 whose counter electrode is grounded, the crystal vibrator 5, and the other end of the feedback resistance 2 respectively. When the circuit is actuated, the 1st inverter 6 performs amplification and oscillation, so self-oscillation is possible and at output stable time, i.e., in normal operation, the 1st inverter 6 stops and only the 2nd inverter(Schmitt inverter) 7 serves for oscillation through automatic switching, so a noise generated in the oscillation circuit is cut without being amplified or grown.

Title: Clutch operating structure for walk type mowing machine
Inventor: OSHIMA HIROSHI
IPC: G05G1/04
Filed: 1987-11-30
Abstract: PURPOSE:To secure the safety of operation with a mowing machine by securing such a constitution where a mowing blade clutch is switched on only when two artificial operations are carried out, i.e., an operation to switch a clutch lever to its ON position and an operation an interlocking member that is operated in a different way from said clutch lever. CONSTITUTION:An interlocking member 14 is kept at an action releasing position owing to the function of a spring 16 as long as no artificial force is applied to the member 14. Then the member 14 is switched to its working position with operation of an interlocking operation tool 15 so that a clutch lever 9 interlocks an operating part 8. At the same time, a mowing blade clutch C is switched on when the lever 9 is switched to an ON position from an OFF position. Therefore the lever 9 does not interlock the part 8 and works idle in case only the lever 9 had a switching action with the member 14 having no switching action. Thus the clutch C is never turned on and therefore the safety is secured with operation of a mowing machine.

Title: Solernoid actuator
Inventor: JIYAAJII HOFUMAN
IPC: H01F7/124
Filed: 1989-11-22
Abstract: PURPOSE: To enhance reliability while reducing power consumption by arranging permanent magnets on the opposite sides of the core of an electromagnet and then exciting the electromagnet to drive a slider fixed to the permanent magnet. CONSTITUTION: A ferromagnetic rod 366 is slid into the central hole 368 of a core 318 in the coil 314 of an electromagnet 3/2. Permanent magnets 364, 340 are secured to the opposite ends of the rod 366 and the magnet 340 is secured to one end of a slider 328. When a current is fed to the coil 314 to generate a field for repelling the magnet 364 and attracting the magnet 340 under a state where a conductor 322 secured to the other end of the slider 328 is touching a contact 324, the magnet 340 approaches closely to the core 318 of an electromagnet 312 and the conductor 322 is separated from the contact 324. It is held at that position even after the coil 314 is de-energized. When electromagnet 312 is energized reversely, the conductor 322 touches the contact 324 again. Consequently, the reliability can be enhanced through a simple structure while reducing power consumption.

Title: Output buffer circuit
Inventor: UENISHI AKI
IPC: H01L21/8234
Filed: 1990-11-09
Abstract: PURPOSE:To reduce the effective value of change with time of an output current, by a method wherein output MOS transistors partly turns on with time lags when input signals are applied, by making the threshold voltages of channels differ in locations. CONSTITUTION:Under a gate electrode 4, a channel region is formed between a source region 6s and a drain region 6d. Impurities are implanted in the channel region, and the threshold voltage is controlled. When the source region 6s is connected with a ground terminal, and a HIGH level signal is inputted to an input terminal 5 from an internal circuit, MOS transistors turn ON in order of low threshold voltage, so that the time is shifted in order of a, b, c. Finally all of the MOS transistors turn ON, and a specified total current flows from an output terminal to the ground terminal. Thereby the effective value of di/dt, change with time of current, can be reduced.

Title: Ultrasonic diagnosing device
Inventor: KOMORI SHOKO

Filed: 1988-11-30
Abstract: PURPOSE:To eliminate work of selecting a filter and eliminate a noise Doppler signal by an organ securely by providing a computation means which determines a frequency spectrum for a detected Doppler signal detecting blood flow information and reducing a compensation signal to a Doppler spectrum signal. CONSTITUTION:The level of each echo signal memorized in a digital scan converter DSC6 is compared with a threshold value memorized in an echo level detecting circuit 12. Every time an echo signal is obtained from a portion designated by a marker, a detecting signal is outputted to a sine wave signal generator 13. Time interval between the detection signals is measured at the sine wave signal generator 13, and the result of this measurement is converter into a frequency. A sine wave of the same frequency as this frequency is outputted for a compensation signal. At an FET computation circuit 9, the compensation from the sine wave signal generator 13 is processed for reduction to a frequency spectrum of a Doppler signal of blood flow speed inputted from an A/D converter circuit 8. A frequency spectrum can thus be obtained only for the blood flow speed with noise Doppler signals by motion of organs eliminated for the output of the FET computation circuit 9.

Title: Amplifier
Inventor: FUKUSHIMA AKIHIRO
IPC: H03F1/34
Filed: 1994-11-15
Abstract: PURPOSE: To provide an amplifier for which the generation of crossover distortion is less and the change of the crossover distortion is less against the change of the bias current of an output stage by providing voltage gain in a driver stage and performing negative feedback from the output stage to the initial stage of a power amplification stage. CONSTITUTION: The transistors Q1-Q4 of the driver stage 3A of the power amplification stage 3 obtain large gain as invertible amplifier constitution. The output of the power amplification stage 2 is power amplified in the power amplification stage 3 and performance required as the entire amplifier is obtained by performing the negative feedback from an output terminal 4 to the power amplification stage 2. Power amplified signals are amplified for both current and voltage in the gained buffer of the transistors Q1-Q4 and a load connected to the output terminal 4 is driven in the SEPP output stage of the transistors Q5 and Q6.  Also, since the output of the transistors Q5 and Q6 is fed back to the emitter of the transistors Q1 and Q2, the closed voltage gain of the entire power amplification stage 3 becomes the multiple of 1 and distortion generated in the output stage 3B becomes 1/(the voltage gain of the driver stage 3A).
