Title: Optical switch
Inventor: SATO MAKOTO
IPC: G02B26/08
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a novel groove shape which prevents the lifting of liquid by narrowing the width of a groove bottom by the perpendicular working tolerance of the groove which is the cause for the deterioration of a reflection characteristic and does not substantially increase the groove length as compared with heretofore in spite of a design allowing for a margin for dealing with the error in the controlled variable of liquid injection. SOLUTION: The groove 2 having a depth to shield the optical waveguides 1 intersecting with each other is formed at the intersecting part of the optical waveguides 1. The liquid 3 having the refractive index equal to the refractive index of the optical waveguides 1 moves at the width of such groove 2, by which this optical switch is actuated. In such a case, both ends of the groove are provided with points w0 of the narrow width. The width w1 in the central part of the groove is wide and the intersecting part of the optical waveguides 1 exists in the central part of the broad width.

Title: Method for molding glass
Inventor: SASAKI TAKUYA
IPC: C03B11/12
Filed: 1991-10-09
Abstract: PURPOSE:To improve mold releasability while maintaining the accuracy and quality of a glass molded product. CONSTITUTION:When glass is filled into a metal mold made of a low m.p. metal or alloy whose m.p. is equal to or lower than the slow cooling point of the glass and the glass is rapidly cooled to the slow cooling point, the rapid cooling is carried out from the outside of the mold to retard the damage of the mold due to melting. At the time when the glass becomes so viscous as to retain its shape after cooling to the slow cooling point, cooling is stopped and the glass is kept at the slow cooling point. The metal mold melts and a glass molded product is obtd.

Title: Detent structure for lock nut
Inventor: KONDO TAKETO
IPC: F16B39/10
Filed: 1994-11-25
Abstract: PURPOSE: To prevent a ring body from coming off from a lock nut and to prevent the lock nut from loosing, by locking a locking pawl in a through hole in the lock nut. CONSTITUTION: A fitting pawl 24 is fitted in an engaging groove 7a of a carrier 7, and is deformed in a diameter decreasing direction, overcoming the urging force of a ring body 22, and accordingly, a lock nut 8 is pressed. Accordingly, the locking pawl 23 is inserted in a through-hole 8a and the locking pawl 23 is pressed outward of the through-hole. Thus, the front end of the locking pawl 23 is bent outward of the lock nut 8, and accordingly, the ring body 22 is prevented from coming off. If the lock nut 8 is applied with a torque in a loosening direction (indicated by the arrow A), a fitting pawl 24 makes contact with a point (a) in a fitting groove 7a while the locking pawl 23 makes contact with a point (b) in the through hole 8a, and accordingly, the rotation of the lock nut 8 is inhibited, thereby it is possible to secure the rotating position.

Title: Focusing regulating device
Inventor: IMANARI HITOSHI
IPC: G02B7/08
Filed: 1990-10-30
Abstract: PURPOSE:To improve control precision of a focusing optical system by a method wherein a slit pattern used for an incremental type encoder for controlling drive of AF and a pattern used for setting of a focus spirit, positioning of a go-home, and control of a speed are formed on a glass base sheet formed integrally with a rotary cylinder for driving a focusing optical system. CONSTITUTION:A slit pattern used for an incremental type encoder for controlling driven of AF and a pattern used for positioning a go-home and controlling a speed are formed on a glass base sheet formed integrally with a rotary cylinder 2 to drive the same focusing optical system L. Thus, manufacture is facilitated, and since a detecting system is not located in the vicinity of a driven motor shaft, an influence on the play of a mechanism is reduced. This constitution controls the focusing optical system with high precision.

Title: Discharge lamp lighting apparatus
Inventor: KOMINAMI SATOSHI
IPC: F21S8/10
Filed: 1994-11-25
Abstract: PURPOSE: To provide two or more light distribution patterns only by a single lamp by making at least one of output frequency and output waveforms of current, voltage, and electric power variable in a lighting circuit and making the discharge arc shape variable. CONSTITUTION: Input a.c. is transformed into d.c. by a rectifying and filtering circuit 14 and transformed into a.c. again by an inverter circuit 19. The output frequency of the circuit 19 is changed to be frequency at the time when transistors 16, 17 are reciprocally turned ON and OFF by a driving circuit 20. When a discharge lamp 11 is started by high voltage pulses, the output from the circuit 19 is applied to a series circuit of the lamp and the lighting is retained and at that time the shape of the discharge arc becomes different due to the alteration of the frequency and light distribution pattern alters based on the position relation with a light controlling means. Also, in the case lighting is retained by the supplied electric power from a power amplifying circuit after starting of the lamp 11, the arc shape is changed by making the output current waveforms be triangular waveforms or rectangular waveforms. Moreover, the current waveforms may be changed by voltage alteration.

Title: Production of welding wire
Inventor: TAKEUCHI HIROKIMI
IPC: B23K35/40
Filed: 1986-12-06
Abstract: PURPOSE:To improve the adhesiveness and welding workability of a wire by subjecting a metallic wire rod to diametral reducing and drawing by using roller dies on which recessed grooves are formed to face each other, prior to resin coating, thereby eliminating the need for a chemical conversion treatment. CONSTITUTION:The metallic wire rods (low carbon steel) 10, 14 are passed through the recessed groves 20 each having a semicircular sectional shape along the circumference of the rollers 18 and are drawn from one side to the other. The wire rod 10 is grasped between the inside surfaces of the grooves 20 and is diametrally reduced and drawn to a fine metallic wire 14 having a small diameter. The resin film (PE, etc.) is then applied on the surface of the wire 14 after the drawing, by which the welding wire is formed. Since the roller dies are used without subjecting the wire to the chemical conversion treatment (phosphoric acid film, etc.), the easy drawing is executable. The production efficiency is improved and the adhesiveness and welding workability of the wire are improved by this method.

IPC: C02F1/58
Filed: 1989-11-09
Abstract: PURPOSE:To efficiently decompose and remove ClO3<-> at a low cost by adding HCHO and HCl to an aq. soln. of an alkali metal chloride contg. ClO3<->. CONSTITUTION:HCHO and HCl are added to an aq. soln. of an alkali metal chloride, e.g. NaCl contg. ClO3<-> by >=0.5mol each based on the amt. of the ClO3<->. The ClO3<-> and HCHO are preferably allowed to react with each other at 70-105 deg.C for >=30 min, especially about 3 hr. The ClO3<-> in the aq. soln. is decomposed and removed. Since inexpensive HCHO is used and the amt. of hydrochloric acid used is reduced, this method is performed at a lower cost than the conventional method. Since the reaction is an exothermic reaction, steam or other energy for maintaining the reaction temp. is not necessary.
