Title: Primary core tooth plate for linear pulse motor
Inventor: SAITO SHINICHI
IPC: H02K41/03
Filed: 1990-07-17
Abstract: PURPOSE:To increase the strength of a bridge and to prevent deterioration of performance of a motor by coupling between pole teeth groups of a primary core pole tooth plate by a networklike coupler. CONSTITUTION:Pole teeth groups (a), (b), (c), (d) having pole teeth are coupled by a networklike coupler (e), and the coupler is formed in the network state thereby to increase the strength of a pole tooth plate. Since a short-circuiting magnetic path between the groups is formed along a regular hexagonal shape, the path is lengthened to enhance a magnetoresistance. As a result, a reactive short-circuiting magnetic flux is reduced, thereby alleviating a reduction in performance due to coupling of the groups.

Patent JP-H0474423-A (JP)
Title: Thin-film forming apparatus
Inventor: SHIBUYA MUNEHIRO
IPC: C23C16/46
Filed: 1990-07-16
Abstract: PURPOSE:To obtain a thin-film formation apparatus which can introduce a gasified raw material into a vacuum chamber without liquefying it again or solidifying it again and which can form a thin film having an excellent characteristic by a method wherein a gas introduction route, an introduction passage and a heating device near it are arranged and the introduction passage and the heating device are installed inside a bellows container. CONSTITUTION:A raw-material solid or a liquid inside an ampule 9 is heated up to a temperature which is gasified or is easy to gasify; it is bubbled by using a gas, from a bomb 18, whose flow rate has been controlled by a flow-rate control device 19. The bubbled raw- material gas is introduced between electrodes which have been heated and whose temperature has been kept by using a heater 22 built in at the inside of an introduction passage 20 and an electrode 21. The heater 22 heats the raw-material gas and, at the same time, heats the electrode 21 faced with an electrode 13. Consequently, the gas introduced from the electrode 21 reaches the electrode 13 without being cooled by an adiabatic expansion which is caused when it is introduced into a vacuum chamber. When a thin film is formed by using this apparatus, the gas which has gasified the liquid or the solid is not liquefied again or solidified again at the inside of the vacuum chamber, the raw material contributes effectively toward forming the film, an abnormal plasma decomposition state is not caused and a decomposition product in a powdery state is very small.

Filed: 1991-07-03
Abstract: PURPOSE:To suppress a noise caused by a charging sound and a defect in an image caused by the fusion of toner by varying the frequency of a vibrating voltage applied to a contact electrifying means in an image formation and in processes except the image formation. CONSTITUTION:The frequency of the vibrating voltage applied to the contact electrifying means 2 is varied in the image formation and in the processes except the image formation. In the processes except the image formation, that is, in the prerotating process of an image carrier 1 when the main switch of a device is turned on, a paper interval during consecutive paper passing, the post rotating process of the image carrier after the image is completely formed, etc., the frequency of the vibrating voltage applied to the contact electrifying means 2 is switched to irreducible lower frequency (the lowerest frequency in a range where electrification unevenness does not occur; the image is not formed on the processes except the image formation so that the frequency of electrification can be lowered up to a region where the interference stripe of a moire image, etc., occur.) than the frequency required in the image formation, as far as any other trouble is not made. Therefore, at least, the charging sound can be made low in the processes except the image formation.

Abstract: PROBLEM TO BE SOLVED: To secure the stability of a phase locked clock signal and to improve synchronous jitter quantity by outputting a clock signal in synchronizing with a trigger signal while a PLL operation is held for a prescribed time in response to a trigger signal. SOLUTION: A reset signal RST synchronized with a synchronous trigger signal HD is inputted from a reset circuit 20 to a gate input part. A holding signal HOLD is supplied to a holding signal input part from a successive phase measuring parts 19. When the HD signal is inputted, the RST signal becomes an H level for a prescribed time. In the period, GVCO 24 in GPLL 17 stops oscillation and makes a phase comparison operation in a holding state. The successive phase comparison part 19 controls output data to a D/A converter 11 so that it reduces the delay quantify of a first variable delay circuit when the judged result is HI and increases delay quantify when it is LO. A latch part 30 latches data to the D/A converter 11 by the holding signal by means of the measurement termination of the successive phase comparison part 19.
