Title: Manufacture of optical waveguide
Inventor: SHINKAI YUJI
IPC: G02B6/12
Filed: 1991-02-13
Abstract: PURPOSE:To reduce the labor and time for waveguide formation by providing a waveguide pattern whose ends are both closed on the surface of a flat plate which has specular surfaces as its end surfaces and filling a light-transmissive material which has a higher refractive index than the flat plate. CONSTITUTION:The flat plate 1 which has the recessed-groove type waveguide pattern 1a, whose ends are both closed, on the surface is molded out of the light-transmissive material by injection molding, etc., and both the end surfaces 1b are finished into the specular surfaces. The distance between the end surface of the recessed groove and the end surface of the flat plate 1 is set to about 1-2mm. Then the light-transmissive material which has the higher refractive index than the flat plate 1 is poured in the waveguide pattern 1a and cured. Then the light-transmissive material 3 having the same refractive index with the flat plate 1 is supplied over the entire surface where the waveguide pattern 1a is formed and cured.

Title: Balance type filter circuit
Inventor: KUSAMUTA YOSHITOSHI
IPC: H03F1/26
Filed: 1988-01-30
Abstract: PURPOSE:To improve an S/N by keeping ground potential constant by connecting each general impedance converter which filters a noninversion input signal and an inversion input signal so as to set a resistor at a ground side, and grounding a connection midpoint via the resistor by connecting those resistors with each other. CONSTITUTION:A current iP that flows from an impedance converter 30 to the ground is offset by a current iN that flows from an impedance converter 31 to the ground because the resistors 12 and 19 are connected with each other. A remaining micro current iG by the above offset flows to the ground via the resistor 32. Therefore, the current permitted to flow to the ground can be suppressed at minimum. In such a way, it is possible to suppress the fluctuation of the ground potential and to improve sound quality.

Title: Ion source
Inventor: OKUNUKI MASAHIKO
IPC: H01J49/16
Filed: 1982-02-10
Abstract: PURPOSE:To generate a stable ion beam for long hours by forming at least a surface part of a needle-shaped member with a metal comprising an alloy able to be ionized. CONSTITUTION:A heatig current is fed between stems 11 and 12 from a heating electric power supply and along with heating of a filament, an alloy 2 inside of a reservoir 1 is heated to be liquidized when heated up above the melting point of said alloy Pt-B and passes through a thin hole 5 on the bottom of the reservoir 1 due to a strong electric field at the tip part of a needle-shaped member 6 to be pulled out up to the tip part of the needle-shaped member. However, as platinum is used for the needle-shaped member 6, the platinum on the surface of said member does not dissolve in the liquid alloy even when the eutectic alloy Pt-B based on said platinum is liquidized. Accordingly, the constitution ratio of the liquid alloy does not change inspite of use for long hours so that the alloy is stably fed to the tip of the needle shaped member 6 without being solidified so far as the heating temperature is above a fixed temperature.

Title: High brightness light-emitting diode flickering device
Inventor: TOYODA MAKOTO
IPC: H01L33/00
Filed: 1995-01-14
Abstract: PURPOSE: To require no transmitting circuit for controlling, shorten a time for designing and the like, and downsize a device and reduce a manufacturing cost resulting from the reduction of the number of parts by utilizing a flickering type light-emitting diode for a control portion. CONSTITUTION: A high brightness light-emitting diode L2 is used in a flickering portion, a transistor TR1 is used in a drive portion, and a flickering type light- emitting diode L1 is used instead of an oscillator OS for control signal generation used in a current light emitting-diode flickering device in a control portion. When a positive voltage is applied to the flickering type light-emitting diode L1 from the positive voltage side of a power source portion, the flickering type light-emitting diode L1 starts to flicker. Since the cathode of the flickering type light-emitting diode L1 takes a voltage in response to flickering (a square wave), the voltage is amplified by the drive portion TR1 as a control signal so as to switch on and off. The high brightness light-emitting diode L2 is flickered by the switching of the drive portion TR1.
