Title: Path correcting system for automatic welder
Inventor: KISHI HAJIME
IPC: B23K9/127
Filed: 1984-10-05
Abstract: PURPOSE:To correct smoothly a welding path of an automatic welder by detecting a welding current value in both right and left end points of a weaving width by utilizing a specified weaving pattern, and providing a means for correcting a weaving center position. CONSTITUTION:A welding current value A in a weaving end point is derived by using a trapezoidal weaving pattern P, etc. constituted so that the right and left end points can be known clearly. Subsequently, a difference (current error value) CE of a current RD and LD detected in the right and left ends of weaving, respectively, is derived. A unit of the derived current error value CE is set, for instance, to 0.1A, and with respect to the current error value CE 0.1A, a unit of a correcting value of a weaving center position is set, for instance, to 0.1mm. In this regard, when the current error value CE exceeds, a path cannot be corrected normally, therefore, this welder is constituted so that its welding work is stopped in that case.

Title: Battery terminal
Inventor: YAMASHITA KAZUNORI
IPC: H01R11/12
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a battery terminal capable of adapting to plural types of battery post. SOLUTION: A battery terminal 10 has a main piece 11 and a presser piece 12 formed individually, both which are coupled together with a bolting mechanism 13 and a switchable locking mechanism 14. The locking mechanism 14 is made up of a locking projection 18, and a deformed slit 17 with a first locking groove 20 and a second locking groove 21, in which the projection 18 is locked. A switchover in the locked position of the projection 18 between the first and second grooves 20 and 21 accordingly narrows or widens the interval between the main piece 11 and the presser piece 12 for adaptation to battery posts P1 and P2 of different sizes.

Title: Optical waveguide
Inventor: HIRUMA TAKEYUKI
IPC: G02B6/30
Filed: 1982-12-01
Abstract: PURPOSE:To obtain an optical waveguide by which the coupling efficiency of an optical fiber and an optical integrated circuit is good and a transmission loss by a bend, etc. of the waveguide is small, by providing a groove whose section is circular on a substrate, and packing this groove with an optical material whose refractive index is higher than that of the substrate. CONSTITUTION:When a tapered mask 3' is formed on a desired substrate 1 and etching is executed by making an argon ion incident vertically from the upper part, the substrate 1 and the mask 3' are etched by non-selectivity of etching. In this case, as for the end part of the mask 3', its dynamical strength is inferior to other part, therefore, it is etched quickly. Usually a substance whose etching rate is sufficiently smaller than the substrate 1 is used for the mask 3', and when etching is executed within the time when an interval L3 of the mask 3' is not varied, it is possible to dig a groove whose depth is D and whose section shape is semi-circular. In this case, thickness L1 of a non-tapered part of the mask 3' is reduced to thickness L1' by etching. In this regard, this semi- circular section structure can be changed by varying a taper angle psi of the mask 3' and a dispersion angle theta of an ion beam.

Title: Data communication method, mobile equipment and radio base station system
Inventor: TATSUMI AKINORI
IPC: H04W4/00
Filed: 1997-07-19
Abstract: PROBLEM TO BE SOLVED: To efficiently suppress the collision of reservation packets by a simultaneous access from mobile equipment by selecting a code out of plural codes on the basis of random number and transmitting the reservation packet by using the selected code when a base station reserves a band with a base station. SOLUTION: When this mobile equipment 1 receives a packet transmission request, a reservation packet for reserving a band for a base station 2 is generated by a reservation packet generation part 4 by way of a packet transmission control part 3. At this time, a code selection part 8 selects a band to which the reservation packet transmits with a random number from a random number generation part 7 and controls a changeover of a switch 9. Thus, the band to which the reservation packet is transmitted is selected at random among plural codes. A radio transmission part 6 inserts the reservation packet in a specified block of a frame of the randomly selected code. In this way, it makes it possible to suppress the reservation packet concentration in a specific code.

Title: Buffer type gas circuit breaker
Inventor: UEMATSU HIROBUMI
IPC: H01H33/91
Filed: 1988-08-24
Abstract: PURPOSE:To positively shut off even large current by blowing insulating gas against an arc after the insulating gas whose pressure is raised by receiving arc energy is moved into a hot gas chamber. CONSTITUTION:When a movable arcing contact 7 is separated from a fixed arcing contact 4 so as to shut off current, insulating gas around an arc is heated by heat of the arc generated between poles, highly pressurized at high temperature, and then moved into a hot gas chamber 1. The gas is then blown against the arc to distinguish the arc. After that, the insulating gas pushed out from a buffer chamber 9 by a piston 7 causes the insulating property between poles to rapidly rise, and thus the shutting off is completed. The larger the current to be shy off, the larger will become arc energy and the higher will become the pressure of the insulating gas in the hot gas chamber 21 and the arc distinguishing capacity of the gas.
