Title: Epoxy resin composition
Inventor: MATSUDA ITSUO
IPC: C08G59/68
Filed: 1986-04-14
Abstract: PURPOSE:To obtain an epoxy resin composition excellent in heat resistance, electrical properties and moisture resistance, and free of corrosiveness, by mixing an epoxy resin with diaminodiphenyl sulfone and a specified cure accelerator. CONSTITUTION:An epoxy resin composition containing an epoxy resin (A), diaminodiphenyl sulfone and a cure accelerator (C) comprising an aluminum compound (i) having organic groups and a silicon compound or organosilane compound (ii) having at least one Si-bonded OH or hydrolyzable group in the molecule. It is desirable that the equivalent ratio of the active hydrogen of the diaminodiphenyl sulfone to the epoxy groups of the epoxy resin used is 0.4-1. When this equivalent ratio is below 0.4, heat resistance inherent in the epoxy resin can not be attained, and when it is above 1, unreacted amino groups adversely affect moisture resistance, undesirably.

Title: Heating furnace having skid rail
Inventor: MASAKI HIDEYUKI
IPC: C21D1/42
Filed: 1980-06-21
Abstract: PURPOSE: To prevent the degradation in the mechanical properties of skid rails and improve the thermal efficiency of a high frequency heating furnace by constituting the skid rails of carbide, nitrode or boride type ceramics in one body with the furnace body in said heating furnace.  
     CONSTITUTION: In the heating furnace which is constituted internally with a furnace body 1 consituting a heating chamber 5, a heat insulating layer 2 and an insulating layer 3 in one body and is inserted into a high frequency heating coil 4, skid rails 12 are formed into one body with the furnace core pipe 11 constituting the inside wall of the chamber 5, and are consitituted of ceramics. Since the ceramics consist of carbide, nitride or boride, they have no need for cooling, increase thermal efficiency and prevent the formation of skid marks. The one body formation of the pipe 11 and the rails 12 results in that the force acting upon the rails 12 is supported by the entire part of the body 1, thus the degradation in mechanical properties owing to the incorporation of ceramics is overcome.

Title: Color noise reduction circuit
Inventor: MOMOKI KENICHI
IPC: H04N9/68
Filed: 1987-04-07
Abstract: PURPOSE:To obtain a chrominance carrier in which the lack of a signal and tailing do not exist and noise is removed by overlapping a vertical non- correlation signal with a difference signal corresponding to a difference between the chrominance carrier and the chrominance carrier which has passed through a cyclic type filter and clipping it so as to set it to a signal for waveform correction. CONSTITUTION:If the output (b) of an adder 3 is supplied to a subtractor 4, the output (c) of the subtractor 4 turns into the signal which can be obtained by overlapping a vertical non-correlation component with the difference between the chrominance carrier and the chrominance carrier which has passed through the cyclic type filter. Consequently, the chrominance carrier component of a vertical outline part in the output (d) of a noise clip circuit 2 comes to be easily saved even if the clip level Lc of the noise clip circuit 2 clipping the output (c) of the subtractor 4 is increased to some degree. Since the output (d) of the noise clip circuit 2 is supplied to an adder 5 and is added to the output of the adder 3, the waveform of the vertical outline part in the chrominance carrier in which the noise component outputted from the adder 3 is reduced is satisfactorily corrected.

Filed: 1993-03-19
Abstract: PURPOSE:To always fix the time required for sheet materials reaching a specific position in an image formation device by settling the position of the sheet materials in the case of switching ON a detection means. CONSTITUTION:Inclination angle alpha formed by an inclination part 6a and a guide plate 1d is set to 60 deg. or less and energizing force applied on a detection lever 6 by a spring is set to 30gf or more. Setting of the inclination angle alphato 60 deg. or less suppresses impact force of a paper sheet 2 which collides against the inclination part 6a from the side in the vicinity of the guide plate 1d. By setting energizing force by a spring to 30gf or more (the impact force or more), even if the paper sheet 2 collides against the inclination part 6a, the paper sheet 2 can sufficiently resist its abutting force and continue to be conveyed so that the paper sheet 2 slides on the inclination part 6a of the detection lever 6 to reach a pressing part 6e and so the detection lever 6 is pressed in the pressing part 6e so as to move rotationally.

Abstract: PURPOSE: To obtain the surface of a silicon substrate flat at an atomic level by a method wherein an electrical field is applied onto the surface of the substrate in an in-plane direction, and lateral etching is selectively promoted in a flattening process wherein the surface of a substrate is flattened through a chemical method. CONSTITUTION: An electric field is applied onto a silicon substrate 1 in an etching solution with electrodes 2, and lateral etching is selectively carried out. That is, when an electric field is applied to the substrate 1, atoms located at a step end are weakened in atomic bond and become liable to be debonded. When etchant reaches to the step end, etching starts selectively from the step end. At this point, no electrical field is present in a depthwise direction, so that etching is restrained from taking place in a depthwise direction. As mentioned above, lateral etching is set larger than depthwise etching in etching rate, the surface of a substrate is flattened, By this setup, a silicon substrate with a surface flat at an atomic level can be obtained.
