Title: Inverter device
Inventor: MOCHIZUKI SUKEYASU
IPC: H02M7/5387
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To suppress a torque ripple and improve an efficiency of a motor to be driven even if a capacitor for smoothing the output of a rectifying circuit connected to a single-phase AC power supply is eliminated or a capacitor of a remarkably small capacitance is used. SOLUTION: An inverter main circuit 4 switches the output of a rectifying circuit 1 connected to a single-phase AC power supply based on a PWM signal from a control unit 8 and thereby generates the AC output to drive a motor 7 at variable speed. The control unit 8 makes a voltage command value based on a speed signal of a rotor or other signals obtained based on a speed command value from a speed setting device 11 and a position signal from a position sensor 10, and then outputs a PWM signal of a pulse width to correspond to the voltage command value. When the control unit 8 becomes a saturated state wherein the inverter output voltage equivalent to the voltage command value cannot be obtained during the increase control of the pulse width of the PWM signal, it quickens the outputting timing of the PWM signal to put the phase of the inverter output voltage forward.

Title: Paper feeding controller
Inventor: OKUDA MASAKIYO
IPC: B65H9/20
Filed: 1988-12-01
Abstract: PURPOSE:To perform paper feeding at proper timing to a sensitizer of a copying machine and thereby prevent any paper jam from occurring by setting the stop timing of a paper feed roller on the basis of time until that when paper fed out of a paper cassette passes through a paper sensor. CONSTITUTION:The time t1 required till paper out of a paper feed roller 4 passes through a paper sensor 8 varies according to paper quality of the paper 2 and abrasiveness of the paper feed roller 4, for example, when it is thin and small in a friction factor as well as the paper feed roller 4 is worn out and so on, it becomes lengthened. Then, another time t2 till the paper feed roller 4 is stopped is calculated on the basis of the time t1. The paper feed roller 4 comes to a stop by the time t2 in the state that the paper 2 has engaged a resist roller 6. A stopped state of the paper at this time comes into a state of being produced with some deflection at the tip part, so that when the resist roller 6 starts its rotation, it is smoothly fed at momentary timing.

Title: Weft tip holder in jet loom
Inventor: ISHIKAWA TATSURO
IPC: D03J1/04
Filed: 1993-11-10
Abstract: PURPOSE:To provide the holder ensuring bright specks not to be developed as a result that the weft tension of a woven fabric on the opposite picking side overcome warp tension. CONSTITUTION:While a picking fluid is yet acting on the tip of a weft, an electromagnet 35 is excited to '-' state to make its pole identical with that of a permanent magnet 32 to energize a holding member 26 toward the side of a second holding member 25, and the tip of the weft 1 picked by a jet fluid from a picking nozzle is held with these holding members 25, 26. Just before beating up, the pole of the electromagnet 35 is made to differ from that of the permanent magnet 32 to effect attraction of the holding member 26 with the electromagnet 35, thus the holding of the tip is released and the weft is relaxed to balance in tension between the weft and a warp.

Abstract: PROBLEM TO BE SOLVED: To reduce a gaseous product by disposing a seal made of a glass rod and a spacer having a higher melting point and a greater height at the outer periphery of a screen between upper and lower plates respectively having an anode and a cathode, followed by heating up to a predetermined temperature in a vacuum. SOLUTION: A seal 20 formed of a soluble glass rod is stuck to the outside circumference of an acting area of a screen on a plate 4 with an anode formed thereon. A few glass spacers 22 are temporarily interposed between the seal 20 and the outside circumference of the acting area of the screen. A melting point of the glass of the spacer 22 is higher than that of the glass forming the seal 20, and considerably higher at that. A plate 1 with a cathode/grid formed thereon is placed on the plate 4, is heated in a vacuum at temperatures higher than the melting point of the seal 20 but lower than the melting point of the spacer 22, followed by mechanical pressing. Consequently, the spacer 22 is crushed, so as to be sealed therearound in a predetermined height by melting of the seal 20.
