Title: Exposure control member
Inventor: WASHIMI AKIYASU
IPC: G03B9/02
Filed: 1979-07-16
Abstract: PURPOSE: To make an exposure control member accurate and light in weight by constituting said member by a synthetic-resin member and a metal member held by the synthetic-resin member.  
     CONSTITUTION: This is constituted by a metal sheet 1 having an aperture forming surface 1a and through-holes 1b, and a synthetic-resin aperture blade 2 holding the metal sheet 1. Blade-driving pins 2a, 2b are integrally formed to the aperture blade 2. Since this construction makes possible the integral forming of a number of kinds of blades by changing the metal member 1 having the aperture forming surface respectively without changing the shape of the synthetic resin holding member 2, it is extremely advantageous in terms of cost. Since the greater portion of the metal sheet part 1 is firmly stuck by the holding member 2, it becomes advantageous in terms of strength and the plate thickness can be made correspondingly thinner, thus the reduction in weight may be achieved.

Title: Optical fiber coupler and its manufacture
Inventor: SASAKI HIROYUKI
IPC: G02B6/28
Filed: 1991-04-23
Abstract: PURPOSE:To increase-a coupling coefficient and shorten the length of an optical coupling part and to decreases the coupling coefficient and reduce wavelength dependency by providing a coupling adjustment part which is different in refractive index from a clad between the cores in the clad of the optical coupling part. CONSTITUTION:The coupling adjustment part 21 which is different in refractive index from the common clad 12 is provided between the cores 13 and 14 of the common clad 12. In this case, when the refractive index is made larger than that of the clad 12, the coupling coefficient between the cores 13 and 14 across the clad becomes larger than that in the absence of the coupling adjustment part 21. The propagation wavelength of this part becomes short because of this coupling adjustment part 21 and the effective coupling length becomes longer than that in the absence of the coupling adjustment part 21, so that when the same coupling coefficient is obtained, the optical coupling part can be made short. The optical fiber coupler which has large wavelength dependency is obtained without decreasing the core diameter. When the refractive index of the coupling adjustment part 21 is made smaller than that of the clad 12, the coupling coefficient between the cores decreases and the wavelength dependency is reducible.

Title: High frequency power unit in plasma equipment
Inventor: YOSHIDA NAOKI
IPC: H03G3/10
Filed: 1990-04-09
Abstract: PURPOSE:To operate a final stage amplifier with a small loss and to improve the reliability by operating the final stage amplifier at the saturation region independently of the quantity of output power. CONSTITUTION:A high frequency oscillating signal whose frequency is, e.g. 13.56MHz is used for the oscillating signal from a crystal oscillator 3 and a transformer is used for a 1st stage amplifier 5 and a final stage amplifier 7 respectively. The final stage amplifier 7 is normally operated at a saturation region. Moreover, the efficiency is constant independently of a DC power supply voltage and the output power and the loss are both in proportion to the DC power supply voltage. Thus, the output power is limited by supply power of the final stage amplifier 7. Thus, the final stage amplifier 7 is operated at the saturation region independently of the quantity of the output power at a small loss and the reliability is improved.

Abstract: PURPOSE:To facilitate forming a trench in a semoconductor substrate with normal taper and facilitate filling the trench satisfactorily with conductive films or insulating films in the trench by a method wherein the deposition speed of wall deposition films deposited on the side walls of the trench and the etching speed are controlled. CONSTITUTION:Wall deposition films 17 are formed on the side walls of a trench 16 and the trench 16 is formed in such a manner that the ratio between the deposition speed of the wall deposition films 17 and the etching speed of a semiconductor substrate 3 is controlled and a self-bias potential is controlled. With this constitution, as the deeper part of the trench 16 has the smaller diameter, the trench 16 can be formed to have normal taper. Moreover, as the opening of the top end of the trench 16 is not attacked by ions of etching because the etching is progressed while the wall deposition films 17 are being deposited on the side walls of the trench 16, the trench 16 can be formed without dimensional variation between the trench 16 and an etching mask 14.

Abstract: PURPOSE: To provide the titled frame in a reduced number of production steps and without material loss by a method wherein plate-shaped synthetic resin blanks split into the shape of plate-shaped synthetic resin blanks split into the shape of comb teeth are subjected to heat and pressure applied from top and bottom forces for lengthening and mutually jointing the projected portions in the shape of comb teeth, and a flange portion is formed along the outside peripheral portion.  
     CONSTITUTION: A sheet frame blank 4 made of reinforced synthetic resin is equally split into the shape of comb teeth to become intermediate frame stocks 5a, 5b and cut at positions indicated by broken lines to a desired length. The thus cut intermediate frame stocks 5a, 5b are placed on a bottom force 8 at certain intervals, the projected portions being opposite to each other and the branch portions 3 being fitted to the holder metals 9 on the force 8. After heating the intermediate stocks 5a, 5b, a top force 6 is lowered so that presser metals 7 lengthen the projected portions 11 in the direction of arrows to mutually joint the projected portions 11 and simultaneously a flange 2 is formed along the periphery. Due to the presence of the holder metals 9, the lengthening or elongation is restricted to the projected portions 11 and in the direction of arrows, i.e. the projected portions 11 are not elongated sideways.
