Filed: 1989-06-21
Abstract: PURPOSE:To provide the title resin excelling in flow during thermoformation and having excellent properties inherent in a vinyl chloride resin by copolymerizing a vinyl chloride monomer with a polystyrene macro monomer in a specified weight ratio. CONSTITUTION:A polystyrene macromonomer having a double bond on one end of a polystyrene chain is produced, for example, by polymerizing a styrene monomer with thioglycolic acid to synthesize a polystyrene having a carboxylic acid on one end and reacting this polystyrene with glycidyl methacrylate. 50-0.5wt.% polystyrene macromonomer is copolymerized with 50-99.5wt.% vinyl chloride monomer to produce a vinyl chloride resin. Part ot the vinyl chloride monomer can be replaced by a copolymerizable monomer (e.g. ethylene). The obtained vinyl chloride resin can be desirably used for pipes, films, electrical components, etc.

Abstract: PURPOSE: To clarify dissolved amounts of an oxide layer, a diffusion region layer, and each layer in a residual part, and enable high precision analysis by an atomic absorption method, by making an oxide film, a metal diffusion region layer, and the residual part of a silicon wafer solutions, and performing quantitative analysis by an atomic absorption method. CONSTITUTION: An oxide film, a metal diffusion region layer, and the residual part of a silicon wafer are dissolved and turned into solutions, and quantitative analysis of the respective dissolved solutions is performed by an atomic absorption method. A frameless atomic absorption method is an atomizing method wherein the atomizing part is constituted of a graphite furnace 3. Electrodes 2 make a current flow in the graphite furnace 3, which is heated by Joule's heat generated by the current. An irradiation light L is generated from a light source of a hollow cathode-ray tube 1. The atomized state in the graphite furnace 3 is irradiated with the light 1, which reaches a detector 6 through a spectroscope 5. Absorption of the light is measured with the detector 6, and outputted to a display part 8 through a signal processing part 7.

Title: Magnetic video recording and reproducing device
Inventor: NAKAMURA KAZUYUKI
IPC: H04N5/783
Filed: 1984-07-31
Abstract: PURPOSE:To make adjustments with a tracking variable resistor, etc., by providing the 2nd fixed head which reproduces a control signal from a magnetic tape at a position different from the 1st fixed head, and switching heads for the 1st and the 2nd control signals during special reproduction such as slow motion reproduction and still picture reproduction. CONSTITUTION:If a magnetic tape already passes through the position where the best tracing is obtained when stop traveling after control signal detection, a changeover switch 9 is placed at the side of a normally open contact 9b. Consequently, a high potential is applied to the control terminal 6c of a changeover switch 6, which is changed over to the side of a terminal 6a, thereby making a selection at the side of a control head 3 provided in front of a control head 4 in the tape traveling direction. Consequently, when the magnetic tape 1 stops running after the control signal detection by the control head 3, the tape is placed in such a state that the best tracing position does not come yet.

Title: Optical disk reproducing device
Inventor: ISHIZUKA KENICHI
IPC: G11B17/028
Filed: 1995-06-26
Abstract: PURPOSE: To obtain a reproduced signal stable in optical axis without deteriorating a disk or changing its structure by holding an optical disk medium between hard plates high in flatness and making their sides opposite to an optical pickup of a laser transmissible material. CONSTITUTION: The optical disk medium 1 and a protective resin layer 3 are loaded onto a lower transmissive type flat surface plate 12 by passing a rotary shaft 8 of a disk stage 9 through them, and are pressed by an upper flat surface plate 11 together with a disk retainer 10. Thus, the optical disk medium 1 is held between the lower transmissive type flat surface plate 12 and the upper flat surface plate 11, and hence rectified in its tilt and corrected into a flat surface. In reproduction, convergent light 6 projected from the optical pickup 4 is transmitted through the lower transmissive type flat surface plate 12 via an objective lens 5 designed to minimize aberration, and is converged on an information recording surface 2 of the optical disk medium 1.  Consequently, the device mechanism is simplified, and the regenerative signal stable in the optical axis of laser light can be obtained without deteriorating the optical disk medium and changing its constitution.

Title: Burning control circuit for burner
Inventor: YUKIMURA MASAHIKO
IPC: F23N5/10
Filed: 1984-07-31
Abstract: PURPOSE:To prevent the release of raw gas from a burner unit by providing an auxiliary discharge circuit for condenser that is formed via a switch which is closed as a manual actuator is brought to its open position. CONSTITUTION:Although a manual actuator 5 is returned to its open position and a normally-opened switch of a selector switch 18 is opened, the residual electrical load in a condenser 13 continues to be discharged via a resistor 19. A normally-closed switch of the selector switch 18 is then closed to allow the discharge by an auxiliary discharge circuit 22, and so, as no electrical load is left in the condenser 13 at the time of extinguishing, a charging electric current which is great enough flowed from a power source 15 to a solenoid 4a. Therefore, such charging electric current cancels the thermoelectromotive current of a thermocouple 12 flowing to an electromagnetic safety valve 3 dur to the residual heat. In this manner, the release of gas from a burner unit can be prevented.

IPC: G03G15/20
Filed: 1990-06-18
Abstract: PURPOSE:To detect jamming by winding by providing a sensor for irradiating the surface of a fixing roller with light and detecting the reflected light. CONSTITUTION:The fixing roller 1 is colored with a low reflectance color, and the surface of the fixing roller 1 is irradiated with the light which is emitted from a light emitting element 2 and passes through the optical fiber 3a, and the reflected light passes through the optical fiber 3b again so that it may be detected by a light receiving element 4. When the jamming by winding occurs, the reflectance on the surface of the fixing roller 1 becomes higher caused by a paper 5, the illuminance of the light l which is transmitted to the light receiving element 4 becomes higher and the light reception detecting level of a light reception detecting element 4 becomes higher. By detecting the difference, the image forming device is stopped, and then, the device is set so that it may not be recovered until the jammed paper 5 is removed and the light reception detecting level becomes lower again. Thus, the jamming by winding can be detected.

Title: Printing plate for printing creamy solder
Inventor: KOBAYASHI MASAO
IPC: B41C1/14
Filed: 1987-06-26
Abstract: PURPOSE:To equalize the printing widths of sides perpendicular to the moving direction of a squeegee and sides parallel to the moving direction of the squeegee, of a creamy solder printed, by setting the width of a sides of a screen stencil pattern perpendicular to the moving direction of the squeegee to be smaller than the width of the sides of the screen stencil pattern parallel to the moving direction. CONSTITUTION:Of four sides of a screen stencil pattern 4A having a rectangular frame shape, the sides 4a perpendicular to the moving direction (a) of a squeegee on a screen printing press have a width W1 smaller than the width W2 of the sides 4b parallel to the moving direction. When a creamy solder is printed on a printed circuit board by use of a printing plate having the screen stencil pattern 4A, the creamy solder is printed in a rectangular frame shape corresponding to the pattern 4A. In this case, there is a tendency that the amount of the solder applied is greater at the sides 4a perpendicular to the moving direction of the squeegee than at the sides 4b parallel to the moving direction. Therefore, with the width of the perpendicular sides 4a initially set to be smaller than the width of the parallel sides 4b, the printing widths of the perpendicular sides and the parallel sides of the creamy solder are equalized.
