Title: Manufacture of liquid crystal display body
Inventor: HOSHIKAWA JIYUN
IPC: G09F9/00
Filed: 1983-10-19
Abstract: PURPOSE:To prevent breaking, cracking, and scratching of a base during manufacturing works and to stabilize quality by fixing a flexible base, such as plastic film base, to a rigid support and carrying out a series of working steps. CONSTITUTION:For example, polyethersulfone film is used for a plastic film base, a transparent conductive film is formed on it, cut to a prescribed size, and it is fixed to a glass plate support 2 with an adhesive tape 3 so as to direct the transparent conductive film outward. A prescribed electrode pattern is formed by screen printing a resist ink on the transparent conductive film in a prescribed electrode, form, etching it with an acid, and then, peeling the resist with an aq. alkaline soln. Working efficiency is greatly enhanced by thus fixing the flexible base to a supporting plate, and a liquid crystal display body using the flexible base can be fabricated at low cost.

Title: Bonding wire and semiconductor device
Inventor: SOYANO SHIN
IPC: H01L21/60
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To increase fusing current per wire while reducing labor required for bonding work in assembling process without sacrifice of bonding performance by employing a bonding wire having such a structure as a copper core wire is coated with aluminum. SOLUTION: A bonding wire 7 being employed for wiring between a power semiconductor chip and a circuit board has such a structure as a copper core wire 7a is coated with an aluminum coating layer 7b. Consequently, a bonding wire having bonding performance equivalent to that of aluminum wire can be attained while sufficiently keeping the advantages in the electrical characteristics of the copper wire 7a, i.e., low volume resistivity and high fusing current. Since the number of bonding wires can be decreased as compared with an assembling structure employing aluminum bonding wire, labor required for bonding work in assembling process can be reduced correspondingly.

Title: Radio equipment
Inventor: SAITO HIROYUKI
IPC: H04B1/10
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent sensitivity suppression due to the higher harmonic component wraparound of a voltage controlled oscillator(VCO) output by varying the output frequencies of a VCO in an operable range, and selecting the output frequencies of the VCO from which the sensitivity suppression is not generated by judging a corresponding detected reception electric field level. SOLUTION: The output frequencies of a VCO 4 are varied in the operable range of a controlling part 1. Then, the reception frequencies of a radio part 2 are set for a reception electric field level detecting circuit 3, and an RSSI level in the reception frequencies is detected, and when the RSSI level is not more than a prescribed threshold value, it is judged that sensitivity suppression due to the output frequencies from the VCO 4 is not generated, and the frequencies of the VCO 4 are set. When the detected RSSI level is beyond the threshold value, the RSSI level is detected for all the set frequencies of the VCO 4, and the output frequencies of the VCO 4 being the RSSI value in the minimum level in the RSSI level stored in a memory 6 are selected and the output frequencies are decided.

Title: Electrode for spot welding
Inventor: AOYAMA YOSHITAKA
IPC: B23K11/30
Filed: 1988-08-05
Abstract: PURPOSE:To prevent falling of a projection nut, etc., and to allow sure welding by constituting the electrode in such a manner that attraction magnetic force is applied to a guide pin and this attraction magnetic force is degaussed as desired. CONSTITUTION:A magnet 7 is detached from a flange 6 to prevent the generation of the attraction magnetic force in the guide pin 5 at the time of fitting, for example, the projection nut 11 formed with a projecting port for welding to the guide pin 5. The nut 11 is then supplied and the guide pin 5 is extremely smoothly fitted relatively into a screw hole. The attraction magnetic force is generated over the entire part of the guide pin 5 and the inside surface of the screw hole of the nut 11 is attracted to the guide pin 5 when the magnet 7 comes into tight contact with a flange 6 after the nut 11 is correctly supplied. The easy falling of the nut 11, etc., from the electrode is, therefore, obviated. The adaptation to an automated line is thus extremely adequate.

Title: Optical disc
Inventor: NAGASAWA MASAHITO
IPC: G11B11/105
Filed: 1994-08-22
Abstract: PURPOSE: To realize stabilized magnetooptical recording by measuring the visible variation in the reflectance on the surface of a disc thereby detecting the relative positional shift between optical spots exiting from a field modulation head and an optical head. CONSTITUTION: When sample servo pit areas are collected, the sample servo pits themselves are tracked by an optical spot of 1μm produced by condensing a laser light having wavelength of 780nm, for example. The collective region of sample pits is regarded as a unit so that a light spot having larger spot diameter, e.g. a light spot from an LED, can be used in the tracking. When the wavelength of a semiconductor laser in an optical head is set equal to that of the LED, the spots 1, 2 have such depths facilitating the diffraction of laser light. Consequently, the light from the LED can be diffusion reflected or diffracted efficiently even if the LED is employed in the tracking and a sufficient variation can be attained in the quantity of reflected light.

Title: Drive control device for cylinder
Inventor: NISHIGAKI MIDORI
IPC: F15B15/22
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To control the moving speed of a cylinder to a predetermined value. SOLUTION: If the pistons 14b, 15b of both an air cylinder 14 and a slave cylinder 15 are moved in synchronism, a differential pressure is produced between both of the slave pressure chambers 17a, 17b of the slave cylinder 15 which are filled with an operating fluid and communicated to each other by a circulation passage 18. A differential pressure detecting device 21 detects the differential pressure between the slave pressure chambers 17a, 17b, and outputs a voltage V1 proportional to the detected differential pressure to a controller 20. The controller 20 inputs a reference voltage Vref1 proportional to a desired differential pressure set by a desired differential pressure setting device 22. The controller 20 supplies air to the driving pressure chambers 16a, 16b of the air cylinder 14 as necessary so that the voltage V1 is the same value as the reference voltage Vref1.  Then the differential pressure between the slave pressure chambers 17a, 17b becomes the same value as the desired differential pressure, and both of the pistons 14b, 15b attain a desired moving speed proportional to the desired differential pressure.

Title: Resistor element
Inventor: NAKAYA TAKEO
IPC: H01C10/30
Filed: 1989-07-28
Abstract: PURPOSE:To prevent terminals from short-circuiting and the insulation resistance from lowering by plating only the sections, which are in contact with conductive patterns, of the output terminals of an insulating substrate on which said conductive patterns and resistor patterns are printed and baked. CONSTITUTION:Terminals 8 are connected to conductive patterns 6 overlappingly and sections 8a are plated with silver with nickel used as a substrate so as to be piled on said conductive patterns 6. After the terminals 8 are connected to an insulating substrate 5, an insulating film 9 is formed to cover the silver plating 8a having the nickel substrate. This structure prevents the silver plating of the terminals 8 from appearing directly on the surface of a resistor element. Therefore, even if water drops are on the surface of the resistor element or between the terminals 8, silver migration by potential differences is prevented and stable contact between the conductive patterns 6 and the plating 8a is kept.
