Patent JP-H07334031-A (JP)
Title: Fixing device
Inventor: SAKAI HIROAKI
IPC: G03G15/20
Filed: 1994-06-07
Abstract: PURPOSE:To provide a fixing device capable of reducing a rush current without making the size of a device large. CONSTITUTION:Until a temperature exceeds a temperature control temp., as the proportion of an ON-time, the whole of a period of 500msec is set to heat ((a) region) and at the point of time that the temp. exceeds the temperature control temp., a heater is turned off. When the temp. is made lower than the temperature control temp, the proportion of the ON-time of the heater in a period of 500msec is made small by 10% and the ON and OFF of the heater are repeated ((b) region). This state is equivalent to reduction in the power of the heater by 10%, compared with the case the ON-time is for the whole of a period and of course the rising of the temp. of a fixing roller is slow as well. Therefore, even in the state where the ON/OFF in a period of 500msec are continued, there is a possibility that the temp. of the fixing roller continuously drops, so that at this time, the ON-time in a period is made long by 5% to recover the temperature of the fixing roller.

Inventor: TAZAWA TAKASHI
IPC: H01H43/04
Filed: 1977-12-09
Abstract: PURPOSE: To correspond the strength of motor rotating direction to the rotating  direction of a pulsator for a washing machine.  
     CONSTITUTION: Magnetic field is imparted oppositely to the temp 2 of a timer time switch 1 to control the time limit of the switch 1 by varying the strength of the magnetic field. This variation of the strength of the magnetic field is controlled by sliding an electromagnet 26 by utilizing the case 12 of the switch 1. The coil of the electromagnet 26 is connected series with the coil of a motor 21 and to a power supply 17 to thereby obtain time limit and to correspond the strength of the motor 21 in rotating direction to the rotating direction of the pulsator in a washing machine to form different period at clockwise and counterclockwise periods. Thus, desired washing vortex can be obtained.

Filed: 1988-06-17
Abstract: PURPOSE:To inhibit the generation of particles as a contaminant to a thin film in a sputtering device by forming a thin layer of fine particles on electrolytic copper foil and setting the copper foil as a contamination preventing material in the device. CONSTITUTION:A thin layer of fine particles of copper or copper oxide is formed on the mat side of electrolytic copper foil by copper plating and the copper foil is set as a contamination preventing material in a sputtering chamber. The desirable surface roughness RZ of the mat side of the copper foil is 5-10mum. The surface of the thin layer of fine particles acts as a surface for capturing particles scattered by sputtering. The copper foil is used only once and then thrown away. Since the copper foil has high heat conductivity and is not electrostatically charged, it is used as the optimum contamination preventing material.

Abstract: PURPOSE:To simplify the control circuit structure by making it possible to stop the stator current vector or to rotate the same only in the forward direction. CONSTITUTION:Current control device 1 feeds the DC current value specified by input command signal 2 to terminals 3, 4. In current control device 1, rectifier 6 rectifies three-phase AC 5 and feeds a DC output to terminals 3, 4.

Error detector 10 outputs error signal 11 indicating a difference between current command signal 2 and detected current signal 9. Phase adjuster 33 receives signals 31 and 32 from phase calculator 30 and processes them. Its output 34 produces main circuit phase command theta11 of the stator current vector. The main circuit phase instruction theta1134 changes following up the stator current vector phase instruction theta131 as the input only in the increasing direction.

At that time, data is written, as shown by (2)', into a matrix register 2 from the host device through a decoder 5. After this, the data of the register 2 is output to the editing memory via a buffer 7 as shown by figure (3)'. In this way, the writing of data from the host device into one matrix register and the reading of data from the other matrix register into the editing memory are alternately performed in the parallel mode. Therefore, it is possible to output data to the editing memory at almost double the speed.
