Title: Production of silver-containing glass
Inventor: OKABAYASHI NAMIHIRO
IPC: C03C1/00
Filed: 1992-01-31
Abstract: PURPOSE:To easily obtain a glass contg. dispersed silver and having an antibacterial property, a photochromic mechanism, etc., by hydrolyzing the reaction product of a metal alkoxide and a specified silver coordination compd. and heat-treating the formed gel. CONSTITUTION:(A) A metal alkoxide (e.g. tetramethyl silicate) is allowed to react with a silver coordination compd. coordinated with (B) an alkoxy metal group-contg. compd. (e.g. N-2-aminoethyl-3-amonopropyl)trimethoxysilane) by using an ordinary solvent (e.g. ethanol). The reaction product is then hydrolyzed in the presence of an alkali (e.g. ammonia) or an acid (e.g. acetic acid) to form a gel. The gel is heat-treated at about 250-1000 deg.C to obtain a glass contg. dispersed silver. The glass is appropriately used as an antibacterial glass, a light control glass, a catalyst, etc.

Title: Micro strip band inhibition filter
Inventor: TAKAHASHI KUNIHARU
IPC: H01P1/203
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a small filter superior in a band inhibition characteristic by wiring a micro strip main line and 1/4 wavelength stubs, which are provided on a dielectric substrate, by bending them. SOLUTION: The three 1/4 wavelength stubs 2, 3 and 4 are provided. They have the lengths of 1/4 wavelength and they are bent by the length of '1' from tips. Intervals between the stubs are set to be 1/4 wavelength. In the micro strip main line 1, a pattern is not linearly formed but it is bent in a rectangle so that it sandwiches the 1/4 wavelength stubs 2, 3 and 4. Then, wiring is executed so that the 1/4 wavelength stubs 2, 3 and 4 become parallel to the main line 1. It is desirable to bend the 1/4 wavelength stubs in such a way that the tips of the 1/4 wavelength stubs 2 and 4 face each other for miniaturization. Then, a space can effectively be used by wiring the 1/4 wavelength stubs in parallel to the main line. Even if they are approximated in parallel, the deterioration of the characteristic by coupling the stubs, and the stubs and the man lines is eliminated.

Title: Cylindrical brushless motor
Inventor: FUKUOKA KIMIMICHI
IPC: H02K29/00
Filed: 1992-02-03
Abstract: PURPOSE:To facilitate process and fixing of a back yoke, to improve a production efficiency and to obtain an ultrathin cylindrical brushless motor by forming a cylinder of a stripe of a magnetic material wound spirally for a yoke. CONSTITUTION:A back yoke 9 is formed in a cylinder by spirally winding a thin magnetic material stripe. Accordingly, as a cylindrical rotor magnet 1 is rotated, a revolving magnetic field is generated, but the magnetic field to be received by the yoke 9 is finely divided by disposing the yoke 9 between a stator coil 8 and a frame 5, thereby reducing an overcurrent to be generated. Thus, a thickness of the yoke in a radial direction can be reduced, a motor having a finer diameter can be obtained, a process and fixing of the yoke are facilitated, and a production efficiency is improved.

Abstract: PURPOSE:To obtain a magnetic sensor apparatus having an accurate output characteristic and a method for the manufacture thereof. CONSTITUTION:With a magnetic field applied to a substrate 3 at a specified angle, the thick film resistor 4 is trimmed and the output characteristic of the hybrid integrated circuit on the substrate 3 is adjusted.

Abstract: PURPOSE:To enable a full-color representation and a gradation representation and to prevent a scumming and an unexpected color-forming, by a method wherein a plurality of fine particles different in color-forming and dielectric characteristics are made of a coloring and decoloring material. CONSTITUTION:Fine particles made of a dye coloring and decoloring by an oxidation reduction reaction and an electrolytic medium having an electrical conductivity sufficient to cause the oxidation-reduction reaction of the dye due to heat are used as a coloring and decoloring material.

Filed: 1980-02-16
Abstract: PURPOSE: To enable to miniaturize subject battery vehicle by a method wherein an erroneous starting preventing device is installed with said vehicle without providing a neutral switch.  
     CONSTITUTION: When a key switch 1 is turned "ON" while a forward or backward movement switch 2 or 3 is turned to "ON" position, a thyristor 19 does not indicate "ON" position because a thyristor 12 is turned to "ON", and as a result, a relay 8 does not work. Therefore, the erroneous starting of the battery vehicle can be prevented with the contact points (a) and (b) of the relay 8 positioned at "ON" and an erroneous operation indicating lamp 10 is lit. On the other hand, when the key switch 1 is turned to "ON" position in the state wherein the forward-and-backward- movement switches 2 and 3 are turned to "OFF" position, the thyristor 19 is turned to "ON" because the thyristor 12 does not indicate "ON" position, and the contact points (c) and (d) indicate "ON" by the function of the relay 8. With the above state of condition, an operation indicating lamp 9 is lit, a relay 5 or 5' is turned to "ON" position by giving an "ON" position to the forward-and-backward-movement switch 2 or 3, and the battery vehicle can be moved forward or backward.

Abstract: PURPOSE: To prevent the damage of a wire, and enhance the speed of the wind ing work by providing a guide roller capable of hooking the wire and protruding and recessing and a pair of guide members on a hook mechanism. CONSTITUTION: A wire W delivered from a wire supplying part 4 through a nozzle part 8 is automatically wound on an integrated type bobbin B by the circumferential motion including the insertion and separation of the part 8 to the bobbin B and the hooking motion of a hook mechanism. Thus, the winding work can be automated, and the speed of the work can be enhanced.
