Title: Plasma cvd method
Inventor: YAMAZAKI SHUNPEI
IPC: H01L21/205
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of a semiconductor device being caused in a film-forming process by means of a plasma CVD method. SOLUTION: In a film-forming process according to this method, film forming of a silicon oxide film 116 to become an interlayer insulating film while using TEOS as a raw material is conducted. Thereby, RF output is oscillated with 50W and after discharge (after Q2 plasma generation) RF output is raised stepwise from 50W to 250W (output value at the time of film formation). Simultaneously with reaching 250W of RF output or with a timing shift TEOS gas is supplied to start film formation. As a result, since RF power supply is oscillated with a low output at the time of starting discharge, a transient big change in a voltage between RF electrodes can be prevented.

Title: Torque motor
Inventor: KONDO JIRO
IPC: H02K26/00
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a torque motor which is capable of staining smooth torque characteristics without generating torque ripples. SOLUTION: One of the poles of a rotor 41 is formed by a group of magnets 43, 46, which consists of a plurality of flat plate magnets 43a, 46a, and the other pole is formed by a group of magnets 44, 47 which consists of a plurality of flat plate magnets 44a, 47a. The flat plate magnets 43a and 46a are shifted in the circumferential direction of the rotor 41 by a half of magnet pitch θA, and the flat plate magnets 44a and 47a are displaced circumferentially along the rotor 41 by a half of magnet pitch θA. Consequently, when the center of the flat plate magnets 43a, 44a corresponds to the edge of the pole of a stator core to generate large torque, the edges of the flat plate magnets 46a, 47a correspond to the edge of the pole of the stator core to generate small torque.  It is thus possible to cancel torque ripples with each other, thereby obtaining almost constant torque within the range of a prescribed rotational angle.

Title: Optical recording medium
Inventor: KAWAKAMI HARUO
IPC: G11B7/24
Filed: 1987-12-16
Abstract: PURPOSE:To prevent a substrate from being thermally damaged at the time of heating by laser light by depositing and forming a high thermal-conductivity transparent cooling layer, 1st protective layer, optical recording material layer, 2nd protective layer, and surface protective layer on the substrate. CONSTITUTION:The high thermal-conductivity transparent cooling layer 7 consisting of AlN, the 1st protective layer 2 consisting of SiO2, the optical recording material layer 3 consisting of a Te alloy, the 2nd protective layer 4 consisting of SiO2, and the surface protective layer 5 consisting of a UV curing resin are formed in this order on the substrate 1 consisting of, for example, polycarbonate. The thermal conductivity of the high thermal-conductivity transparent cooling layer is thereby made larger than the thermal conductivity of the 1st protective layer 2. The heat of the optical recording material layer 3 is, therefore, effectively diffused in a horizontal direction by the high thermal- conductivity transparent cooling layer 7 even if said layer is heated by the laser light and the heat thereof is diffused through the 1st protective layer 2. The substrate is thereby prevented from being thermally damaged.

IPC: H03H9/64
Filed: 1988-12-16
Abstract: PURPOSE:To realize the phase characteristic varied approximately linearly with respect to the frequency by combining a major resonance and a sub resonance adjacent to the major resonance in terms of the frequency in a 2-port surface acoustic wave resonator so as to form a duplicated mode and making the frequency interval between the major resonance and the subresonance narrow. CONSTITUTION:Two interdigital transducers 14, 15 are formed between a couple of reflectors 12, 13 at a prescribed interval on a piezoelectric substrate made of a material such as a crystal. A strongest voltage standing wave caused between the reflectors 12, 13 among the waves is used as the major resonance E and the other standing wave is a spurious (subresonance) wave D. In order to use the spurious radiation D together with the main resonance E, the subresonance D is approached to the main resonance E by increasing number of couples of the interdigital transducers 14, 15. That is, the frequency interval between the resonance E and the subresonance D are made narrow so that the radiation D adjacent to the main resonance E in terms of the frequency are coupled with each other to be in the duplicate mode and so that the attenuation versus frequency characteristic has a peak characteristic.
