Title: Core
Inventor: TASAKA MOTOO
IPC: B41J35/00
Filed: 1985-06-11
Abstract: PURPOSE:To effectively preventing weaving of a narrow strip member such as an ink ribbon for use in an impact printer or the like on winding thereof by forming a core around which the ink ribbon is wound on the outer surface serving as winding surface with a plurality of projections. CONSTITUTION:A core 1 is a cylindrical member provided on the outer surface 2 serving as winding surface with a plurality of projections 3. The size and the form of the projection 3 are limited in consideration of puckering caused thereby, and preferably it is a rounded member having a maximum diameter of 10mm and a maximum height of 1mm. Two projections 3 or more are enough and these projections 3 may be aligned along the center line of the outer surface, or they may be arranged in a staggered manner on both sides of the center line. When a ribbon is wound around the core 1 of such a construction, the ribbon which might be weaved is caught by the projections 3, and consequently it can be positively prevented from weaving.

Abstract: PURPOSE:To decrease insertion losses, by setting either on one of electrode  groups of input electrode or output electrode group as electrode parts of two  series connections and connecting an inductance or a distributed constant line in  parallel parallel with any electrode part. CONSTITUTION:An input electrode is formed with a pair of electrodes 1-1 and 1-2 in series connection and similarly an output electrode is formed with a pair of electrodes 2-1 and 2-2 in series connection. The operating frequency bands of both the electrodes are adjacent to each other, and an inducator 4-1 is connected in parallel with the electrode 1-2 and also an inductor 5-1 is connected in parallel with the electrode 2-2. In selecting the resonance frequency of the electrode 1-2 and the inductor 4-11 and that of the electrode 2-2 and the inducator 5-1 to a frequency higher than the operating frequency band, the electrodes are inductive within the operating frequency band. Since the electrodes 1-1 and 2-1 not connected with the inductors are capacitive, the set of the electrodes 1-1 and 1-2 and that of the electrodes 2-1 and 2-2 can both have the reesonance frequency.

IPC: C23C14/06
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To provide a process capable of producing a magneto-optical disk improved in the durability of repeated recording characteristics in a unitary target sputtering process. SOLUTION: In a film forming process used for the production of an optical disk, pulse driving is adopted for a d.c. sputtering process.

Filed: 1983-07-11
Abstract: PURPOSE:To ensure the accurate detection of an ignition signal and to make it possible to control an engine effectively by a computer and the like, by making the ignition signal a pulse shaped signal, and counting the number of the pulses. CONSTITUTION:The signal from an electromagnetic pickup 11, which is provided in an ignition plug, is rectified by a diode 12 and compared with a reference voltage Vs in a comparator circuit 13. The output signal from the circuit 13 is counted by a counter circuit 16. Meanwhile, a clearing signal is sent to the counter circuit 16 from an Ig signal processing circuit 19. The counting is performed only during a section corresponding to the ignition signal Ig. When the counted value equals to a preset value or more, the signal is judged to be the ignition signal, and the signal is outputted from an output terminal 20. When the counted value is less than the preset value, the signal is judged to be a noise signal and not outputted. Therefore, the ignition signal is detected positively and accurately.

Abstract: PURPOSE:To prevent the generation of defective leakage generated through the implantation of impurity ions to the side surface of a U-shaped groove when forming a U-shaped groove isolation by selectively etching a SiO2 film on the bottom of the U-shaped groove and thinly forming the SiO2 film. CONSTITUTION:A U-shaped groove 2 is formed through selective etching while using a SiO2 film 6 shaped to a Si base body 1 as a mask. A SiO2 film 3 is formed to the inner surface of the groove 2. The film 3 is dry-etched to selectively etch only the film 3 on the bottom of the groove 2. A SiO2 film 3a on the side surface of the groove 2 is not etched at that time. B ions are implanted to introduce B to the base body 1 through a film 3b on the bottom of the groove 2. B is not introduced by the thick film 3a on the side surface of the groove 2 at that time. Accordingly, the generation of leakage along the side surface of the isolation groove 2 can be prevented.

Title: Apparatus for measuring field curent of brushless synchronous machine
Inventor: SAGARA TATSUO
IPC: G01R31/34
Filed: 1982-07-16
Abstract: PURPOSE:To measure a field current without providing a measuring apparatus in a rotor shaft, by detecting the field current of a brushless synchronous machine by a field current detecting pick up provided to a fixed side. CONSTITUTION:A DC current rectified by a rectifier 5 is flowed to the connecting conductor 7 connecting the rectifier 5 and a field current winding 3. Induction electromotive force due to interlinkage magnetic flux increased in proportional relation to the DC current flowing to the conductor is generated in a pick up 11 provided to a fixed side. The timewise change in voltage induced to the pick up 11 formed by winding a semi-circular core with a coil at an equal interval pitch comes to a triangle wave form. This triangle wave form is changed to a DC signal by a wave form treating circuit 12, for example, an integral circuit and the DC signal after change is inputted to an ammeter 13 to be indicated. By this mechanism, it is unnecessary at all to mount a measuring apparatus to a rotor side and reliability is enhanced.
