Title: Annealing method for optical disk
Inventor: NAKAMICHI NIRO
IPC: B29C71/02
Filed: 1993-09-06
Abstract: PURPOSE:To improve the optical characteristics of an optical disk of a reflection type by heating this optical disk to increase the temp. from ordinary temp. up to a temp. below the thermal deformation temp. of the optical disk, thereby annealing the optical disk. CONSTITUTION:A CD 30 is placed on a glass plate 24 in such a manner that its recording surface faces this glass plate and AC 100V is impressed to a cement resistor 8. This resistor generates heat. The generated heat is transmitted by radiation and convection to an aluminum plate 20, by which the temp. nearly uniform over the entire surface is maintained within the annealing device 1. The annealing treatment is executed by increasing the temp. from room temp. at a ratio of 20 deg.C in one hour and holding the temp. for six hours at the point of the time when the CD 30 attains 80 deg.C. The temp. is controlled by a control circuit in such a manner that the temp. is dropped at a ratio of 10 deg.C in one hour. The temp. is controlled to about <120 deg.C, i.e., the thermal deformation temp. at which the deformation of the CD 30 is resulted. As a result, the apparent heat capacity of the CD 30 increases and the change in temp. is minimized.

Title: Positioning device
Inventor: IGARASHI HAJIME
IPC: G05D3/12
Filed: 1985-11-05
Abstract: PURPOSE:To increase the positioning speed for repetitive shift and stop of a stepper, etc., by controlling the distance, the speed, vibrating state, etc., against an X/Y stage at a time point where the X/Y stage is switched to the position servo from the speed servo so that those factors are all equal at every step. CONSTITUTION:The speed servocontrol is performed in a section SS between time points tA and tE and the position control is carried out in a section PS between time points tE and tP respectively. The section includes an acceleration section AB where the acceleration is applied at a fixed speed, a high and fixed speed section BC where the X/Y stage moves at a high and fixed speed Vmax, a deceleration section CD where the deceleration is applied, and a low and fixed speed section where the X/Y stage moves at a low and fixed speed Vmin. The length of linear sections AB, BC and CD of acceleration and deceleration and a DOWN speed switching point C are decided from the difference of the present position (start point A) and a target position point P, i.e., the shift distance of the X/Y stage. It is available to set automatically the reference time T used for decision of tolerance at an optimum level in order to minimize the time between the start point A and a stop point P. Otherwise the speed Vmin is optimized for each step in order to minimize the time needed for position servocontrol.

IPC: F21V7/22
Filed: 1987-09-30
Abstract: PURPOSE: To form a reflector excellent in heat resistance, and having a narrow angle light distribution or a precise light distribution without applying secondary machining such as surface polishing or the like by forming of polyimide resin film of specified thickness. CONSTITUTION: The base body 1 of a reflector is molded, for example, into a quadric surface body of revolution with polyimide resin film of a thickness of 0.1 to 0.3 mm having surface smoothness. A flange part 2 and an annular rib 3 are integrally formed on the outside of the opening edge of the base body 1, an annular rib 4 is respectively formed on the periphery of the lamp insertion hole 7 of the base body 1 top part and plural ribs 6 are radially formed at predetermined intervals on the reflection face 5 of the base body 1. Since the infrared transmittance decreases if a film thickness exceeds 0.3 mm, it is not preferable. Thereby, the reflector can be formed with the lightweight film having good formability so as to have shape holding intensity and be superior in heat resistance.

Title: Substrate-developing device
Inventor: NISHIMURA JOICHI
IPC: H01L21/683
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To provide the substrate-developing device which can obtain the uniform developing result. SOLUTION: A cup 30, which surrounds the periphery of a substrate W, is arranged in a processing chamber 1. For the cup 30, down flow is supplied by a fan filter unit FFU, and an exhaust pipe 40 communicated to an exhausting means at the outside of the device is connected at the same time. Furthermore, the adjustment of the amount of air intake by a fan 21 and the adjustment of the air exhausting amount by an air exhausting dumper 45 are controlled by a control part 50. When developing liquid is supplied on the substrate W or during development, air absorption and exhaustion are stopped. Thus, the waving of the developing liquid layer formed on the main surface of the substrate W is eliminated. As a result, the uniformity of the development is improved.  In the meantime, when rinsing liquid is supplied on the substrate W or the rinsing liquid is dried, the air absorption and exhaustion are performed. Thus, the scattering of the rinsing liquid ejected from the substrate W and the escape to the outside of the cup 30, the flying up of the rinsing liquid and the re-attaching to the substrate W and the contaminating of the substrate W can be prevented.

Filed: 1990-09-18
Abstract: PURPOSE:To obtain plural branching optical signals having a sufficient margin by providing an optical distribution means using an optical coupler so as to branch an optical signal amplified with an optical signal amplifier means and outputting a branch ing optical signal to the transmitter. CONSTITUTION:The transmitter is provided with an optical signal amplifier means 1 which receives an exciting light oscillated from an exciting light source and a trunk line optical signal fi from one end and outputs a trunk line optical signal fo to other end via a rare-earth doped optical fiber 3 by using a stimulated light and with an optical distribution means 6 which uses the optical signal amplified by the optical signal amplifier means 1 and by branching with optical couplers 8-10, and outputs branching optical signals f1-f4. For example, let a gain of the optical signal amplifier 1 be 15dB and its saturation output be +10dBm, and a ratio of the trunk line optical coupler 7 be 50:50, when the trunk line optical signal fi inputted from a terminal T1 is -5dBm, the trunk line optical signal fo outputted from a terminal T4 is +7dBm and branching optical signals f1-f4 outputted from terminals T5-T8 are +1dBm. Thus, in this case, the transmitter acts like an optical branching amplifier and can be used as the optical distribution amplifier by changing the ratio of the trunk line optical coupler 7. Thus, plural branching optical signals having a sufficient margin are obtained.

Title: Sensor without power supply
Inventor: YAMAZAKI SHINICHI
IPC: G01D5/245
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain a sensor in which a gap is not formed between a cylindrical bobbin and a casing in the hardening operation of a potting agent and which prevents the occurrence of an irregularity in an output voltage by a method wherein the potting agent is injected and hardened in a state that the cylindrical bobbin is pressed to the side of the casing by using a jig. SOLUTION: A casing 1 is held inside the recessed part 11a of a jig 11. An upper jig 13 is placed on a bobbin protrusion part 3A. Respective bolts 14 are tightened. A cylindrical bobbin 3 is pressed downward by the upper jig 13 via the bobbin protrusion part 3A. Thereby, the tip of the bobbin 3 is brought strongly into pressure contact with the tip inner face of the casing 1, and a gap is eliminated. In this state, a potting agent 12 is filled into the casing 1. Then, the potting agent 12 flows to the side of the bobbin 3 via a split groove 3Aa so as to be spread to the whole at the inside of the casing 1. In this manner, since the bobbin 3 is always pressed to the tip side by the jigs 11, 13, the contraction action of the potting agent 12 does not reach the bobbin 3 when the potting agent 12 is hardened, and no gap is generated between the bobbin 3 and the casing 1.

Abstract: PROBLEM TO BE SOLVED: To detect a liquid level when the liquid level is lowered to a prescribed level in a vessel housing a fluid to be conveyed to a solid sample filling layer in the case where a zeta potential existing on a solid-liquid interface is obtained by means of a fluid voltage measuring method. SOLUTION: A pressurized gas introducing tube 36, a fluid discharging tube 52 and a cylindrical-shaped temperature-measuring resister 9 are provided in a vessel 1. A temperature detection element 91 of the temperature-measuring resister 9 is provided to a position slightly upper than a level of a lower end section 53 of the fluid discharging tube 52.
