Title: Manufacture of clad contact strip material
Inventor: TAKAHASHI TOSHIAKI
IPC: B21B27/03
Filed: 1989-01-23
Abstract: PURPOSE:To prevent a contact strip material from contaminated by a Cu-Ti alloy and to eliminate weakening of a contact interface so as to improve contact intensity by pressing and forming the contact strip material on the periphery by a roll that has a convex of the width slightly wider than that of the contact strip and resistance-welding it in a non-oxidizing atmosphere at the same time. CONSTITUTION:A contact strip material 3 is brought into contact with a concavity 2 of flat reverse trapezoid that is formed on a base strap material 10 of Cu-Ti alloy in the upper middle part in a longitudinal direction. By a roll 8 that has a convex 7 of the width slightly wider than that of the contact strip material 3, which is pressed and formed on the periphery and resistance-welded in a non-oxidizing atmosphere at the same time. Since the contact strip material 3 is pressed and formed on the periphery by the roll 8 that has the convex 7 of the width slightly wider than that of the contact strip material 3, and is resistance-welded in the non-organizing atmosphere, the Cu-Ti alloy of the base strap material 1 is not adhered or deposited on the convex 7 of the roll 8 by which the contact strip material 3 is pressed and formed. As the base strap material 1 does not touch the peripheral surface of other than the convex 7 of the roll 8, the Cu-Ti alloy is not adhered or deposited. Precious metallic alloy of the contact strip material 3 is not bonded on the roll 8 through the Cu-Ti alloy. Contact interface is not weakened and contact intensity is thus improved.

Title: Heating roll for fixing device
Inventor: HAMABE KOSHI
IPC: G03G15/20
Filed: 1987-01-26
Abstract: PURPOSE:To eliminate defective adhesion of a metallic ring occurring in the difference in the coefft. of thermal expansion of a metallic ring material for power feeding to be provided on a supporting roll having a surface consisting of a ceramic material by specifying the coefft. of thermal expansion of said material. CONSTITUTION:A material having <=20X10<-6>(l/K) coefft. of linear expansion is used as the annular electrodes 5, 5a of a heat fixing roll formed by providing an exothermic layer 3 on the surface of the supporting roll 2 having the surface consisting of the ceramic material and forming the annular electrodes 5, 5a, connected electrically to both ends of said exothermic layer thereto. The coefft. of thermal expansion of the ceramic material or ceramic layer to be used therein is usually <=10X10<-6>(1/K). Since the coefft. of thermal expansion of the adhesive layer is equalized in the above-mentioned manner, shearing forces do not act at all between both and the exfoliation of the adhesive surface does not arise. Electric power is thus stably supplied to the roll for a long period of time and the generation of defective contact, current leakage, etc., is obviated.

Filed: 1980-02-07
Abstract: PURPOSE:To enable quick and accurate control, by making a delay or lead the scanning of the even number order to that of an odd number order, through giving a slight shift of the position of a plurality of heads. CONSTITUTION:The head position of two heads is slightly shifted so that the scanning track can repeat coarse and fine as shown in Figure. The recording tracks 4, 5 of an even and odd number order and the playback tracks 6, 7 of those, are set so that the phase of the recording and playback tracks can be shifted by 180 deg.C. Thus, in playing back the recording track 4 of the odd number order, it is traced 7 to an even number order and the recording track 5 of an even number order is tracked 6 to the odd number order. Further, the recording and playback tracks are shifted each other slightly. The shift of the playback tracks 6, 7 to the recording tracks 4, 5 is discriminated for the direction, allowing to correct the shift for optimum tracking control.

Title: Starting method and starting circuit for sensorless motor
Inventor: YONEMURA KOHEI
IPC: H02P6/06
Filed: 1991-01-14
Abstract: PURPOSE:To reduce the possibility of start failure considerably. CONSTITUTION:The starting method of a motor having no sensor for detecting the rotation of rotor comprises a first starting step, a pause step and a second start step wherein each of the first and second start steps includes a step for feeding a step signal and a step for feeding an acceleration or constant speed signal. When the starting operation fails at the first starting step, the rotational speed is lower than a predetermined level but it is not zero. Consequently, the motor can be started positively if brake operation is not performed but the second starting operation is performed after a pause. According to the invention, probability of start failure after repeated starting operations can be considered substantially zero.
