Abstract: PURPOSE:To enable many deep etching pits to be formed uniformly and densely by a method wherein an average height, an average pitch, and a cross angle of the first group of projection streaks and the second groups of projection streaks are set at specified values. CONSTITUTION:A first group of projection streaks 1 consisting of a plurality of projection streaks 10 with an average height H1 of 0.1-10mum and an average pitch P1 of 1-20mum and a second group of projection streaks 2 consisting of parallel projection streaks 20 which cross projection streaks 10 of the first group 1 and have an average height H2 of 0.1-10mum and an average pitch P2 of 1-20mum are formed by transfer of recess streaks of a roll over the surface. It is necessary to set cross angle alpha between a projection streak 10 belonging to the first group 1 and a projection streak 20 belonging to the second group 2 at 10-170 deg. to form a sufficient number of etching nuclei dispersed more equally. This enables much increase in the enlargement ratio of an electrode foil and an increase in electrostatic capacitance.

Abstract: PURPOSE:To provide a titled device which can adjust freely the opening angle and opening width of a scarfing groove by constituting the device in such a way that the oscillating angle of a freely oscillatable arm and the position of a torch support with respect to the oscillating arm are adjusted. CONSTITUTION:A holder driving motor 24 is driven while a shaft 34 is offcentered by a suitable distance (a) from the shaft 26a of a gear 26 then the gear 26 is rotated via a gear 25 by the motor 24 and a case 27 for adjusting an eccentric distance is thereby rotated integrally therewith. An oscillating arm 14 is moved via a connecting rod 31 by such rotative motion and since the shaft 34 is off-centered from the shaft 26a, the rotating motion of the case 27 is converted to the rotating motion of the arm 14 around a torch oscillating shaft 10 thereby oscillating an electrode around the shaft 10. The oscillating angle alpha of an electrode 19 is determined by the distance (a). The distance (b) between the extension line 10' of the shaft 10 and the top end of the electrode 19 is adjusted by rotating a feed screw 16 by a knob 17 and moving a torch support 15 toward the diameteral direction of the shaft 10.

Abstract: PURPOSE:To perform reproduction correctly even when recording is performed with a beam on one side and the reproduction is performed with the beam on the other side by arranging light emitting points for recording and reproduction asymmetrically with the optical axis of a convergence optical system. CONSTITUTION:In an array type semiconductor laser 1, two light emitting points for recording and reproduction are arranged asymmetrically with the optical axis of the convergence optical system, and the light emitting point 21 for reproduction is located outside the optical axis of the light emitting point 22 for recording. Light emitted light for recording and reproduction are shown in dotted line and continuous line. An alternate long and short dash line shows the stray light of a recording beam. The stray light of the recording beam generated at a beam splitter 4, after being reflected on a recording medium 6, is separated from a reproducing beam directing toward optical detectors 11 and 12 and the convergence optical system, and angles directing toward the optical detectors are set equal. Consequently, the stray light can be prevented from being made incident on the light receiving plane of the reproducing beam of the optical detector by being superimposed, and the influence of the recording beam on a reproducing waveform immediately after recording can be suppressed, thereby, recording information can be reproduced correctly.

Filed: 1990-04-18
Abstract: PURPOSE:To smoothly change the engaging force of a lock-up clutch at the time of change in mode by setting pressure regulating characteristics by a pressure regulating valve in such a way that change in working fluid pressure at the lock-up releasing side by means of the actions of the second spool of a shift valve and a pressure regulating valve is roughly kept continuous against change in second fluid pressure. CONSTITUTION:In a slip condition, working fluid pressure in a chamber at the lock-up releasing side is regulated by the pressure regulating action of a pressure regulating valve 60 in response to controlled fluid pressure by a second control means 72. This thereby allows the engaging force of a lock-up clutch 30 to be controlled. In addition, when the switching action of a shift valve 50 due to change in second control fluid pressure is performed in connec tion with the pressure regulating action of a pressure regulating valve 60, change in the working fluid pressure of a chamber 34 at the lock-up releasing side is roughly kept continuous against change in second fluid pressure. By this constitution, the engaging force of the lock-up clutch 30 is thereby increased and/or decreased smoothly.
