Title: Production of chlorinated vinyl chloride resin
Inventor: FUJIMOTO TERUO
IPC: C08F8/22
Filed: 1993-09-07
Abstract: PURPOSE:To obtain the resin easy to be gelled at relatively low temperatures and capable of providing molded forms of high impact strength, by chlorination of polyvinyl chloride with its polymerization degree distribution curve having two peaks, having a specific polymerization difference between the two peaks and specific number of low-polymerization degree molecules.

Title: Signal amplitude limit circuit
Inventor: HIRASAWA KAZUO
IPC: H04N9/68
Filed: 1994-10-13
Abstract: PURPOSE: To minimize the attenuation in a high frequency signal by connecting 1st and 2nd resistor in series with a base of a transistor(TR) and connecting a Zener diode and a diode in series between earth and a connecting point between the 1st and 2nd resistors. CONSTITUTION: A signal whose maximum amplitude is limited to an amplitude limit voltage VS is fed to a TR 7 by making a sum of a Zener voltage of a Zener diode 5 and a forward voltage of a diode 6 equal to the voltage VS. On the other hand, since the diode 6 is not conductive with respect to a signal whose amplitude is less than the voltage VS, the capacitance is less than 1/10 of the capacitance of the diode 5. As a result, the attenuation in the signal at a high frequency band due to the capacitance is reduced. Furthermore, a capacitor 2 is connected in parallel with a resistor 3 to reduce the signal attenuation at the high frequency by the resistor 3, then a prescribed characteristic is obtained. Moreover, the function of preventing the oscillation is provided by adding newly the resistor 4.

Abstract: PURPOSE:To realize more precise alignment in size between an optical stop and a light source image by making a diameter of a part shutting light continuously variable according to the number of tape windings. CONSTITUTION:Light which has passed through a part without ultrasonic waves in a water tank 4 is shut by a variable diameter optical stop 13 which is continuously adjusted to appropriately shut the light in such a state. That is, a circular part comprising a core rod 17 and a tape 16 wound around the core rod 17 shut the light, wherein a diameter of the circular part and winding of the tape 16 are appropriately adjusted to shut the entire light.

Abstract: PURPOSE: To eliminate the position displacement of a pair of rollers to feed sheets in a further simplified the constitution by moving an energized bearing means within a range of play in accordance with rotation for eliminating the displacement in the case where position of one roller to the other roller is displaced. CONSTITUTION: An upper register roller 6 gets closer to a lower register roller 9 to move to a specified position, when a diagonally lower side surface of an outer circumferential surface of an upper bearing 24 on the operator's hand side gets in contact with a cut guide part 32a to slide in contact with an inclined surface. In the meanwhile, an upper bearing 24 on the depth side moves in contact with an inclined surface of a cut guide part 32b on the depth side to slide in such a direction as to eliminate displacement. After coupling of an upper and a lower parts of a copying machine main body with each other is completed, the lower register roller 9 is provided with rotation force from a drive part to start rotating.  The upper bearing 24 moves within a movable range in a gap formed between an outer circumferential surface of itself and an inner surface 25 at an edge part, thereby residual displacement can be eliminated completely.

IPC: H01L23/50
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To suppress package cracks by preventing peeling on the interface of a film-like die bond material between the die pad of a lead frame and a semiconductor element. SOLUTION: A die pad 2 has plural rows of plural through-holes 4, which are arranged linearly alternately to stripes of a film-like die bond material 3. The film-like die bond material 3 has a width of 1 mm or longer, and the distance 8 between the rows of the through hole 4 is set longer than the width of the film-like die bond material 3.

Title: Tube heater
Inventor: SHINADA HIDEHIRO
IPC: H05B3/44
Filed: 1989-09-25
Abstract: PURPOSE:To improve a starting performance and a low noise, and to realize a long service life by providing bendings in specific intervals to a heating circuit. CONSTITUTION:To a heating wire 2 housed in a spiral formation inside a heat- resisting tube (a quartz tube) 1, bendings 10 are provided at the intervals of 2-5 times the diameter of the heating wire 2. As a result, the hard tensile force of the heating wire 2 is increased extensively by the bendings 10, and the heating wire 2 is contacted to the inner surface of the heat-resisting tube 1 in the point contact condition making a fairly small contact area. And thereby, the heat loss to the heat-resisting tube 1 is suppressed, and starting performance can be improved. Consequently, an electromagnetic oscillation noise in the power feeding is reduced considerably, and the rigidity of the heating wire 2 is improved remarkably by the bendings 10, generating no deformation to the heating wire 2 even in the lighting period. Therefore, a short circuit and a deterioration of the heat-resisting tube by the deformation can be prevented, and a long service life of the heater is realized.

Filed: 1992-09-18
Abstract: PURPOSE:To uniformly roast foods to be cooked by uniformizing thermal distribution in a cooking chamber. CONSTITUTION:The volume of a heat-storing chamber R2 placed in the preceding process of cooking is formed larger in comparison with the volume of a cooking chamber R3. Hot air from a combustion chamber R1 is sufficiently distributed in the heat-storing chamber R2 and is thermally uniformized, following which the hot air is allowed to flow into the cooking chamber R3 via a partition 13. Therefore, high-temperature atmosphere in the cooking chamber R3 where hot-air temperature is uniformly distributed in the direction of its width can be realized.
