Title: Production of optical modulator
Inventor: MATSUMOTO KIYOTO
IPC: G02F1/035
Filed: 1992-02-21
Abstract: PURPOSE:To provide a process for production by which the optical modulator of a wide frequency band is easily obtd. CONSTITUTION:An LiNbO3 substrate 11 is fixed on a stage 4 movable in a horizontal direction by positioning the surface formed with electrodes 14 downward. A metallic mask 2 having apertures of about 1 to 3mm width and 20 to 40mm length is fixed onto the LiNbO3 substrate 11. A KrF excimer laser is oscillated at 100 to 200Hz pulse repetitive frequencies and while the stage 4 is moved back and forth on a straight line, the LiNbO3 substrate 11 is irradiated with the laser by a condenser lens 3. Grooves of about 500 to 700mum depth are thus formed by abrasion in the aperture parts of the metallic mask 2.

Title: Manufacture of sealing body for battery
Inventor: KOSHIBA NOBUHARU
IPC: H01M2/12
Filed: 1980-03-19
Abstract: PURPOSE:To increase the explosion resistance and enhance the mass production capability of a sealing body having a circular-arclike thin part which serves for the safety of a battery by breaking, by providing a resin-pouring gate, from which a resin subjected to injection molding is poured, at a symmetrical position relative to the thin part about the center of the sealing body. CONSTITUTION:A sealing body of an explosion-proof battery is provided with a thin part 22 which breaks when the internal pressure of the battery becomes unusually high, thereby any gases being discharged toward outside the battery. The sealing body is manufactured by pouring a thermoplastic resin into an injection- molding metal mold. Here, the shape of the former thin part 22 is a circular arc 5 which extends in the direction of the concentric circle of the sealing body, and a resin-pouring gate 3 provided in the molding metal mold is located at a symmetrical position relative to the former circular-arclike thin part 5 about the center of the sealing body. Owing to the above constitution of the metal mold, the welded surface of the poured resin coincides with the thin part 5. Consequently, the thin part 5 has less strength than any other part of the sealing body and efficiently works for the prevention of the battery explosion.

Title: Production of highly viscous gelatin
Inventor: NAKAJIMA TAKANORI
IPC: C09H1/00
Filed: 1991-03-01
Abstract: PURPOSE:To obtain efficiently highly viscous gelatin which contains no impurities without need for chemical treatments with a crosslinking agent, etc., by heating dry granular gelatin to such an extent that it is not insolubilized and thus increasing the viscosity of the gelatin. CONSTITUTION:Gelatin such as alkali-treated gelatin or acid-treated gelatin is formed into fine granules and dried preferably to a water content of approx. 18% or less. Then the dry granular gelatin is heated to such an extent that it is not insolubilized by external heating using an oven, etc., or internal heating including high-frequency heating. Thus the molecules of the gelatin are joined with each other so that they are highly polymerized. In consequence, the viscosity of the gelatin is increased and highly viscous gelatin is obtained. In this process, the viscosity of the resultant gelatin can be adjusted by controlling the time for the heating treatment. Further, in the heating treatment, no chemicals nor treating agents are used and hence there is no bad influence on the human body. The highly viscous gelatin thus obtained can be used advantageously in foodstuffs, for medical use or the like.

Title: Method for controlling output of welding power source
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/06
Filed: 1984-02-27
Abstract: PURPOSE:To stop feeding of a welding wire in the state that allows easy starting of next welding by feeding welding current during short-circuiting of the wire after completion of welding and stopping power supply to a wire feeding motor, and cutting off current in the state of non-short-circuiting. CONSTITUTION:In the method of controlling output of welding power source used for consumable electrode type arc welding, welding current is supplied during specified period according to wire feeding speed after cutting off power supply to a wire feeding motor in finishing welding and the welding wire is consumed. When a sign of non-short-circuited state or short circuit and breakage is detected by fluctuation of welding current or voltage, current is cut off or reduced to prevent formation of large droplet. When short circuit of the welding wire is detected after this, current is raised again to consume the wire. By repeating above-mentioned method of controlling welding electric power until short circuit of the welding wire stops to occur, short-circuiting of the welding wire with a molten pool and the formation of large droplet at the top are prevented.

Abstract: PURPOSE:To improve the easiness of attachment and detachment by providing the tip parts of an upper and a lower tapered pin part with an engagement projection part and an engagement hole which engage the tapered pin part with each other detachably on the same axis. CONSTITUTION:The tip parts of the upper and lower tapered pin parts 3b and 3a of the lower reference pin 1a which has the lower tapered pin part 3a and the upper reference pin 1b having the upper tapered pin part 3b are provided with the engagement projection part 4 and engagement hole 5 which engage the tapered pin parts with each other detachably on the same axis. A base material 13 and a film 12 are fixed where the size of their reference holes equals the size of the diameter of the upper and lower tapered pin parts, but the upper and lower tapered pin parts 3a and 3b contact the reference holes of the base material 13 and film 12 at a certain angle at the fixation point. Consequently, the contacting area decreases and the friction force between the reference hole and reference pin at the time of insertion becomes small to facilitate the attachment and detachment of the reference pin.
