Title: Wheel cutter
Inventor: IKEDA MAKOTO
IPC: B28D1/24
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To form a scribing groove with a uniform depth and being excellent in continuity along a curve with a small radius of curvature, and cut a fragile material plate into a desired shape by tilting the rotating shaft of a wheel at a specified angle to the surface of the fragile material. SOLUTION: The rotating shaft 2 of a glass cutter wheel 1 is tilted at 10-45 deg. to the surface of a fragile material 3, and the tip of the wheel comes into contact with the surface of the fragile material into an arc form. For this reason, when the wheel 1 is advanced along a curve which is bent in the same direction as the arc, even if the radius of curvature of the curve is as small an arc as the diameter of the wheel, a favorable continuous scribing groove is formed. Therefore, the fragile material can be cut into a desired shape, e.g. a curved shape with a small radius of curvature of approx. 5mm. Also, the change of a pressure in the circumferential direction, which is applied to the blade tip, becomes gentler compared with a wheel of a smaller diameter, and the blade tip is not worn out, and the life of the wheel can be extended.

Filed: 1989-09-27
Abstract: PURPOSE:To prevent the open circuit of transparent electrodes and back electrodes by extending transparent electrodes and back electrodes to solder connection sections respectively, and laminating transparent conducting films 9 at the lowest layer and metal films 10 with good solder wettability at the highest layer on solder connection sections. CONSTITUTION:Transparent electrodes and back electrodes are extended to solder connection sections respectively, and transparent conducting films 9 are laminated at the lowest layer and metal films 10 with good solder wettability are laminated at the highest layer on solder connection sections.

Title: Antenna matching device
Inventor: YOSHIKAWA MITSUO
IPC: H04B1/04
Filed: 1989-09-27
Abstract: PURPOSE:To attain high speed matching by connecting plural reactance elements in using as variable reactance elements in series or in parallel via a switch or the like, and varying the combination of ON, OFF of the switches so as to vary a combined reactance. CONSTITUTION:Matching information at a prescribed frequency such as transmission frequency is stored in a memory memo and a control circuit CONT controls a matching circuit TUNE based on the information. When the matching is taken again because of the start of transmission or change of the transmission frequency, for example, a relay control voltage is turned on/off to take an optimum capacitance based on the optimum matching information in said transmission frequency. Or the matching is taken by changing the voltage applied to a switching element to switch the combination of switches momentarily. Thus, since the time requiring to take matching is enough to be a time switching a switch such as a relay, the high speed matching in comparison with a conventional antenna matching device is attained.
