Title: Transporting condition determining method for powder and granular material inside hopper and device thereof
Inventor: TAKESHITA KAZUHIRO
IPC: G01F23/14
Filed: 1995-03-27
Abstract: PURPOSE: To precisely determine whether powder and granular material inside a hopper is normally conveyed, stuck, or conveyed out completely from the hopper when varied kinds of powder and granular material such as combustion ash generated in a boiler is transported from the hopper. CONSTITUTION: In a method by which powder and granular material 2 inside a hopper 1 is sucked to a conveying pipe 4 so as to be transported, a differential pressure is measured between a space above the powder and granular material 2 inside the hopper 1 and the inside of the conveying pipe 4. A change in the differential pressure with the lapse of time is continuously measured, while a change in the differential pressure is found in every lapse of the predetermined time. A device is provided with pressure sensors 5, 6 arranged in the space above the powder and granular material 2 inside the hopper 1 and in the inside of the conveying pipe 4, a differential pressure gauge 7 connected to both sensors 5, 6, and a computing determination device 8 connected to the differential pressure gauge 7.  In this way, a transporting condition of combustion ash can be determined with high precision even when a combustion condition in a boiler is changed, so that troubles during transporting work can be solved.

Title: Electrostatic recording medium
Inventor: OONISHI MASARU
IPC: G03G5/02
Filed: 1978-06-06
Abstract: PURPOSE: To make possible printing in positive polarity surely without causing dot missing while making best use of the characteristics of high definition of positive polarity by providing the specific dielectric layer on a conductive base member.  
     CONSTITUTION: The dielectric layer 12 composed of an insulation type inorganic pigments 9, conductive inorganic pigments 10 and organic regin finder 11 is provided on conductive base paper 8. Pulse voltage of positive polarity is applied to the multi-stylus head 1 on this electrostatic recording paper 13. In the region A, electrons are injected from the base paper 8 into the pigments 10a and are released to the voids near the same. With these field emission electrons as a start, the discharge spreads over the entire part of the electrode 1. In the region B, the conductivity of the pigments 10b is large and when the dielectric relaxation time is sufficiently shorter as compared to the applied voltage pulse width, the internal fields of the pigments 10b become nearly zero. Hence, this results in that high electric fields are applied to the voids near the region B, thus increasing discharge propability. With this discharge as a start, the discharge spreads over the entire part of the electrode 1, thus dot missing is nearly perfectly prevented.

Title: Printed circuit board
Inventor: TSUNASHIMA EIICHI
IPC: H05K1/03
Filed: 1988-03-23
Abstract: PURPOSE:To achieve a high reliability by mounting a semiconductor chip directly on a substrate by a method wherein the substrate is made of para-aramid base materialim pregnated with epoxy resin in a specific ratio and its surface is coated with a conductor layer. CONSTITUTION:An insulating substrate 1 is made of polyparaphenylene 3-4' diphenyl ether terephthalamide paper impregnated with 55-60% weight ratio of epoxy resin mixed with aromatic polyamine adduct hardener or of cloth base material plate. On this insulating substrate 1, a copper foil conductor 2 and a silver plated layer 3 are established and semiconductor chips are sticked to the silver plated layer and are connected by wires 5. The para-aramid paper has a high heat resistance. By impregnating epoxy resin into the para-aramid paper, a heat resistance of the insulting substrate 1 increases depending on the impregnated material. By this, even if semiconductor chips are mounted directly on the substrate, thermal damages can be avoided and a high reliability can be achieved since a longitudinal strain of temperature of both the chips and the substrate is equal.

Filed: 1980-05-26
Abstract: PURPOSE: To improve the reduction of area, by forming an annular recess groove along the circumference of a work zone of a work, and by applying a coining work to the work.  
     CONSTITUTION: A work 5 is pressed by a cylindrical punch 11 having inner diameter d 1  equal to the diameter d 2  of a round work zone 6; hereby, an annular recess groove 12 is formed along the circumferential edge 7 of the work zone 6. A coining work is then applied to the work zone 6 by pressing with a punch 15 having outer diameter d 4  equal to the inner diameter d 1  of the punch 11. Hereupon, when the punch 15 presses the work zone 6, the work zone 6 surrounded by the groove 12 causes a plastic deformation and a part of the work zone 6 flows into the groove 12. As a result, the thickness t 3  of the work zone 6 is reduced to a prescribed thickness displaying a deformation resistance smaller than that in case of a conventional method. A circumferential embankment 18 formed around the cavity 2 by the said coining work can be eliminated by an additional work.
