Title: Self-supporting type optical cable
Inventor: ISHIKAWA HIROKI
IPC: G02B6/44
Filed: 1995-05-09
Abstract: PURPOSE: To provide a self-supporting type optical cable which prevents the elongation and increase in transmission loss of coated optical fibers. CONSTITUTION: Supporting wires 3 and an optical cable core 4 are covered and integrated with a common sheath 5 continuous in a longitudinal direction. The length in the longitudinal direction of a neck part 5a changes periodically in the longitudinal direction of the self-supporting type optical cable and, therefore, the optical cable core 4 has an extra length to the supporting wires 3 in a tensionless state. The part of the neck part 5a is easily deformed and the distance between the cable core and the supporting wires 3 changes in the state of applying the tension on these wires and, therefore, the occurrence of elongation and distortion in the optical cable core 4 and the application of a compressive stress thereon do not arise.  Then, the coated optical fibers 6 do not elongate and meander within the slots of the optical cable core 4 regardless of before or after the impression of the tension.

Title: Gas laser device
Inventor: YOSHIOKA YOSHIFUMI
IPC: H01S3/03
Filed: 1990-04-23
Abstract: PURPOSE:To obtain stable glow discharge even at the end sections of a main discharge electrode pair by mounting sections not fixed only by the specified times of length in the longitudinal direction of curved surface sections at both ends of anode discharging surfaces in support bars to chambers at both ends of an anode. CONSTITUTION:The discharging surfaces of an anode 12a are formed in curved surfaces only by a distance (x) in the longitudinal direction toward end faces respectively from points C1 and C2 at both end sections of the anode 12a. Support bars 21a and 21n at both end sections of the anode 12a are fixed at positions separate only by a distance L respectively from each end face of the anode. An excellent result is displayed between one and a half times and twice and a half times of the distance (x) by an experiment regarding the distance L in this case, and it is confirmed that twice is particularly favorable. The inhibition effect of the generation of arc discharge is weakened at both end face sections when L is less than one and a half times, and no glow discharge is generated at both end sections and power is reduced when L exceeds twice and a half times. Field strength in the longitudinal direction including both end sections of the anode is equalized, thus suppressing the generation of arc discharge, then acquiring stable glow discharge.

Title: Mold for vertical centrifugal casting
Inventor: HONMA UMEO
IPC: B22D13/10
Filed: 1979-08-31
Abstract: PURPOSE: To shorten the distance where molten metal flows and decrease the production of oxide by directly extending the pouring inlet of molten metal up to the mold cavity.  
     CONSTITUTION: The mold has a molten metal pouring inlet 1 consisting of an annular groove of which central shaft aligns to the rotating shaft and end extends up to the mold cavity 3. Hence, the molten metal poured flows directly into the mold cavity 3 through the molten metal pouring port 1. The annular groove is so installed that the flow passage of the molten metal becomes as short as possible. Thereby, the distance where the molten metal flows is considerably decreased and the disturbance of the molten metal is less. Thereupon, even at the time of casting of metals such as aluminum and aluminum alloy which are easily oxidized, the formation of oxide is less and the defects of casting are decreased.

Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a substrate processing method and its processing device for realizing miniaturization and lightening, and obtaining a substrate with high dimensional accuracy. SOLUTION: Marking-off lines on a non-metallic material substrate 1 by a cutter 2 are formed to be narrow in width, and shallow. Since cracks 9-1-9-4 occur by irradiating the marking-off lines with a CO2 laser beam and make the substrate 1 easily dividable, not only the substrate 1 can be processed at high dimensional accuracy, but also the occurrence of chipping at the time of forming the marking-off lines can be restrained at a minimum level. Further, since a CO2 laser device is fixed, it does not require to move the laser device by putting on a mobile stage for moving the laser device in a X direction. The processing device can thus be miniaturized and lightened.
