Title: Polyhydroxynaphthalene and epoxy resin composition
Inventor: NAKA AKIHIRO
IPC: C08L63/00
Filed: 1992-08-31
Abstract: PURPOSE:To obtain the title compound which is obtained by co-condensation reaction between alpha- and beta-naphthol and paraformaldehyde, thus contains a specific amount of the component containing a plurality of naphthalene nuclei, and can be used as a curing agent for semiconductor-sealing epoxy resin because it gives heat-resistant and humidity resistant cured products. CONSTITUTION:alpha-, beta-naphthols and formaldehyde is charged in a reactor equipped with a stirring mechanism, a reflux condenser, a thermometer and a nitrogen inlet, and stirred for 8 hours at 110 deg.C in a nitrogen atmosphere to effect co-condensation reactions. Then, the reaction mixture is heated up to 200 deg.C and the unreacting substances are removed under a pressure of 5mmHg. Hg. The co-condensates are determined for its number of naphthalene nuclei and found to include less than 50wt.% of 4 or more nuclei products. Thus, the product is suitable for sealing semiconductors because it has a low melting point and melt viscosity, excellent operability and is used as a curing agent to give cured epoxy resins of high glass transition point, heat resistance and humidity resistance and high crack resistance of the package on welding treatment.

Title: Pulse width modulation system
Inventor: MORIKURA SUSUMU
IPC: H03K7/08
Filed: 1988-10-13
Abstract: PURPOSE:To maximize S/N at the time of demodulation by specifying the size of pulse width to be changed by modulation in accordance with the period of a repeated pulse signal. CONSTITUTION:An input signal (a) is sampled by a repeated pulse signal (b) with a period T and the pulse width of the repeated pulse signal (b) is changed by the sample value. When it is defined that the size of the pulse width to be changed by modulation is DELTAW and the degree (m) of modulation is m=DELTAW/T, the degree (m) of modulation is proportional tp the amplitude of the input signal. On the other hand, the frequency component (spectrum distribution) of a signal can be found out by Fourier analysis and a repeated pulse signal can be found out by Fourier series expansion. Consequently, the value of DELTAW maximizing the S/N is DELTAW=(2/3)T. When the size of the pulse width to be changed by modulation is set up to 2/3 of the period of a repeated pulse, the S/N at the time of modulation can be maximized.

Abstract: PURPOSE: To enable a full automatic operation and a repeated use thereof without a rupture thereof, by disposing a protective element having PTC-resistance characteristics which depend on temperature with a socket housing and a minus contact portion in series electrically, so as to make the protective element thermally connected with the socket housing. CONSTITUTION: When an ignition plug is pressed into a socket housing 2, the wall of the ignition plug comes into contact with the wall of the socket housing 2, while a glow element of the ignition plug comes into contact with a bimetal spring contact 5. Due to such a construction, an electric current which heats the glow element flows to a minus contact portion 3 by way of a plus contact portion 4, the bimetal contact 5, the housing wall of the ignition plug, the socket housing 2, a bottom wall portion 6 and a protecting element 1. Self-heating is generated in the protective element 1 and a leakage current flows when the temperature reaches a given limit temperature. This leakage current prevents heating which exceeds an allowable range. When a cause of an overload is removed, the protecting element automatically returns to the start position.

Title: Image synthesizing printer
Inventor: SHIODA KAZUO
IPC: G03B27/52
Filed: 1988-10-13
Abstract: PURPOSE:To prevent the lowering of photographic image contrast by providing photographic paper masks where microshutters are arranged in a matrix condition on an exposing stages. CONSTITUTION:A color paper 1 is led from a magazine 2 by a first pair of carrying rolls 20 and set on a first exposing stage 4 on which a photographic image is printed. In the rear step of a loop forming stage 6, a second exposing stage 7 for exposing a CRT image is provided. Masks 10 and 11 are composed of liquid crystal display panels, and a common transparent electrode is formed in one transparent glass in which a liquid crystal is sealed. In another transparent glass, individual transparent electrodes in a dot shape are formed in the matrix condition. Thus, since mask patterns can be electrically changed, synthesized image layout is easily performed. Hereby since light-shielding is properly performed, two images are printed without duplicate exposure and the lowering of the photographic image contrast due to sub-exposure effect is prevented.

Filed: 1990-09-27
Abstract: PURPOSE:To prevent generation of a large bending stress in jaws by causing disengagement when an actuator is depressed, allowing the jaws to open the the outside, and supporting the jaws by the supporting part of the actuator. CONSTITUTION:When an actuator 3 is raised, pawls 1 are covered with a jaws cover 2 and shut inward, and when the actuator 3 is depressed, the jaws 1 are disengaged from the jaws cover 2, hung out from a gap 3e, opened to the outside, and are supported from the inside by the supporting part 3b of the actuator.

Title: Armature for commutator type rotary electric machine
Inventor: NIIMI MASAMI
IPC: H02K13/04
Filed: 1993-10-15
Abstract: PURPOSE:To omit coil ends of both sides by individually interposing inner conductors between both end faces of an armature core and an outer conductor along both end faces connecting a radial inner end to radial inner end of the outer conductor, and connecting the radial outer end to an armature coil. CONSTITUTION:Inner conductors 41 are respectively fixed to both end faces of an armature core 11 through resin insulator 41a, and outer conductors 42 are respectively fixed to surfaces of both side inner conductors 41 through resin insulator 42a. The insulator 41a, the conductors 41, the insulator 42a and the conductors 42 of right side of the core 11 constitute a commutator 4 used also as a coil end. On the other hand, the insulator 41a, the conductors 41, the insulator 42a and the conductor 42 of left side of the core 11 merely constitute a coil end. Thus, since both side coil ends can be omitted, an axial length, physique and weight of a motor can be reduced without restriction in a high speed rotation by its centrifugal force resistance.
