Abstract: PROBLEM TO BE SOLVED: To provide the regular winding a coil into an equal thickness by providing a phase advance means for advancing a signal phase of a main spindle by a prescribed quantity in a control means for controlling a drive means based on the output of an encoder and by controlling a traverse shaft to reversely rotate, when the traverse shaft is advanced by the winding width of a bobbin. SOLUTION: When a coil 18 is wound around a coil bobbin 14, a controller part 38 rotates a spindle motor 24 at a prescribed speed via a main spindle servo amplifier 34 and rotates the main spindle 12 having the coil bobbin fitted thereto via a belt 28. A traverse shaft motor 32 is normally/reversely rotated via a traverse shaft servo amplifier 36 based on the output of a synchronous encoder 20 directly connected to the main spindle 12 so that the regular winding across the whole winding width of the coil bobbin 14 is implemented. Then, an encoder phase advance part is provided in the controller part 38 and the main spindle speed is advanced by a prescribed time so that the phase delay caused by the delay in the traverse shaft motor is compensated, thereby providing superior regular winding.

IPC: H05B41/00
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To shorten the restarting time of a lamp after occurrence of a momentary break in a power supply by installing an external starter parallel with a discharge lamp through a switch which is operated with the time difference between two timers having different delay times installed on the power supply side of a stabilizer. SOLUTION: When a momentary break is generated in a power supply, a lamp remains in the put-off condition even if the power supply is restituted. At the same time as the momentary break, timers 17 and 18 are reset, among which the one 17 starts counting at the same time as the power restitution, and after the time-up, its output relay is actuated, while the other 18 remains still counting and its output relay is left out of actuation and its contact is left closed. This generates the condition that the source voltage is impressed on an external starter 5, which causes emission of the start pulse. In the lamp 6, a high temp. condition is lasting, so that thermal responsive switches 11 and 12 remain open and no source voltage is impressed on the internal starter, and no actuation will take place.  Therefore, the lamp can be restarted easily in a short time by the operation of the external starter 5.

Title: Toner concentration detecting method using magnetoresistance element

IPC: G03G15/08
Filed: 1978-11-17
Abstract: PURPOSE:To measure toner concentration by applying the magnetic flux leaking from a magnetic roll through developer to a magnetoresistance element and measuring the resistance change of the magnetoresistance element. CONSTITUTION:The direction of spontaneous polarization Ms of ferromagnetic material metal is determined by the magnitude of the magnetic field to be applied from the outside and the resistance changes with the directions of the spontaneous polarization Ms. Now, a ferromagnetic material thin film of rectangular strip form is considered as a magnetoresistance element. When current i0 is flowed in the lengthwise direction of this film, a potential difference V proportional to i0 is produced between the termianls A, B, but if i0 is made constant, V becomes the one expressing a resistance R. Hence, by measuring the magnetic flux 11 leaking through a developer 12 from a magnetic roll 10 as the resistance value of this magnetoresistance element and comparing the same as against the resistance value corresponding to a reference toner concentration, the toner concentration in the developer may be detected.

Abstract: PURPOSE: To prevent noise produced from a drill head by connecting a rod to the tip of a hammer, providing an oblong hole in each shaft center of a hammer rubber substitute struck by the hammer, press-fitting a liner as a vibration-proof material in the oblong hole. CONSTITUTION: The tip of a hammer 13 is inserted until it comes into contact with the upper end of a hammer rubber substitute. Pressure oil supplied to a hose adapter 11a from a pressure oil source through a hose or the like is fed into a cylinder body 12 through a distributor valve 11 to reciprocate the hammer 13. The tip of the hammer 13 continuously strikes a hammer rubber substitute. Simultaneously, the hammer rubber substitute is rotated by an oil motor to strike while rotating. A first liner 13b made of nonferrous metal is press-fitted as a vibration-proof material in an oblong hole 13a provided in the shaft center of the hammer 13. Whereupon, as materials with different frequencies are closely combined, they cancel each other to lower the magnitude of noise. Thus, the effect of noise prevention can be increased in a simple structure.
