Abstract: PURPOSE:To preform smooth change-over with less variation of a valve lift curve and restrain sound of tappets by increasing the diameter of a base circle of a high speed cam so as to absorb plays caused by errors manufacture and assembly of rocker arms. CONSTITUTION:A minimum value Emin of a play E between an engaging part 20 of a high speed rocker arm 4 and a hydraulic piston 14 is absorbed by increasing the diameter of a base circle 12a of a high speed cam 12 so as to eliminate the risk of interference between the hydraulic piston 14 and the engaging part 20 of the high speed arm 14, and accordingly, a large part of the play can be absorbed in a condition in which smooth change-over can be made while the difference between the maximum play Emax and the minimum play Emin can be absorbed by a ramp part so that the variation of an equivalent cam lift curve, as shown by the solid line in Fig. 1 (b), is less that of the case in which the difference Emax-Emin between the errors is not absorbed as shown by the broken line, thereby it is possible to carry out smooth change-over from a low speed range into a high speed range and to restrain sound of tappets.

Filed: 1990-09-19
Abstract: PURPOSE:To pattern a magnetic thin film made of an NiFe, a CoNiFe, etc., with a high precision at a high speed by using gas, where inert gas and gas including chlorine in molecules are mixed, to remove the exposed part of the magnetic thin film. CONSTITUTION:The NiFe film 12 is accumulated on a substrate 11, and a photoresist 13 is formed on this film 12, and the NiFe film 12 is dry-etched with gas where Ar and CCl4 are mixed in 1:1. When gaseous chlorine is introduced for the purpose of etching the magnetic thin film essentially made of Co, Ni, and Fe at a high speed, materials such as an FeCl3 having a low boiling point are generated on the surface of the magnetic film, and the magnetic film is made easy to etch, and further, it is physically etched by gaseous Ar, and then, the etching speed is increased. Thus, the magnetic thin film made of an NiFe, a CoNiFe, etc., is paterned with the high precision at a high speed.

Title: Laser beam machining method for glass and glass formed parts
Inventor: IKENO JUNICHI
IPC: B23K26/00
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To directly machine fine deep holes on glass without causing a crack with YAG laser beam. SOLUTION: Pulsed oscillation YAG laser beams are radiated to an object to be machined that is made of glass containing a component high in YAG laser beam absorptivity. The irradiation energy of YAG laser beam is set at a prescribed threshold or higher in accordance with the high YAG laser beam absorptivity component contained in the glass to be used. The focal position of the laser beam is set near the middle between the front and the rear faces of the object to be machined, more suitably in the part lower than such middle position, dispersing the irradiation energy uniformly in the thickness direction rather than concentrating in a specific position, and growing a through hole from both front and rear faces. Thus, simplification of the machining process and operation can be contrived as well as reduction in the machining time and cost.

Abstract: PURPOSE:To prevent a side etch of an electrode pattern and roughness and difference in levels of a base layer from occurring by a method wherein a lower electrode of a stacked capacitor constituting a memory cell is constituted so that an insulation film is enclosed in the electrode. CONSTITUTION:A part forming a lower electrode of a stacked capacitor is covered with photoresist 13, and then with the photoresist 13 used as a mask a polycrystal silicon layer 8b, a PSG film 9 and a polycrystal silicon layer 8a are etched to be removed. At this time since the polycrystal silicon layer 8a is a thin film, the polycrystal silicon layer in a recess on a chip can be completely removed even with short-time etching. After a polycrystal silicon layer 8c is deposited on the entire face, with the polycrystal silicon left on sides of the PSG film 9 by etch-back, the PSG film 9 is enclosed by the polycrystal silicon layer 8. Thus side etch of an electrode pattern and occurrence of roughness and difference in shift of a base layer can be prevented.

IPC: H04B7/26
Filed: 1988-10-04
Abstract: PURPOSE:To realize antenna turning in the best state automatically without the need of reducing the Q of the antenna by constituting a variable condenser of an antenna tuning circuit with a varactor diode and controlling the condenser with a signal from a PLL local oscillation circuit. CONSTITUTION:A signal of a frequency component different from a desired frequency corresponding to a digital signal of a signal line 17 by just an intermediate frequency is outputted from a signal line 15 and a voltage corresponding to the frequency of the line 15 is generated in the line 9. Since a varactor diode is used for a VCO 61 to vary the oscillated frequency, the circuit has only to be controlled by taking the case into account in such a way that the voltage of the line 9 is higher when the frequency of the line 15 is high and when the frequency is low, the voltage is lower. That is, the voltage of the line 9 is amplified properly by a buffer amplifier 7 and given to the varactor diode 111, then an optimum tuning condenser is obtained from the diode 111. Thus, the voltage from a PLL local oscillator 6 is given to the diode 111 to obtain a condensor in response to each radio frequency.
