Title: Check valve
Inventor: SUEMATSU OSAMU
IPC: F16K15/02
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent a back flow by securing sufficient sealing when micro pressure is applied to an outlet. SOLUTION: When an inlet 6 of a casing 2 applies fluid pressure to a valve element 3, a check valve 1 allows the fluid to flow by separating the valve element 3 from a valve seat 8 in opposition to energization force of a spring 4. When an outlet 7 of the casing 2 applies fluid pressure, the check valve 1 prevents the fluid from flowing back by pressing the valve element 3 vertically to the valve seat 8 based on the energizion force of the spring 4 and the fluid pressure. The valve element 3 includes multiple center ribs 10 slidable along the inlet 6 to guide the valve element 3 itself toward the valve seat 8, and multiple outer ribs 11 slidable along the casing 2 to guide the valve element 3 toward the casing 2.  The spring 4 is installed near the outside of an outer diameter of the valve seat 8 by engaging each outer rib 11 with a stopper 5, and presses the valve element 3 vertically to the valve seat 8.

Title: Secondary battery having nonaqueous solvent electrolyte
Inventor: TOBISHIMA SHINICHI
IPC: H01M10/0567
Filed: 1993-06-29
Abstract: PURPOSE:To enhance high voltage resistance and the charge characteristic of a negative electrode by using a nitroalkane represented by a specific formula as an additive to a nonaqueous solvent. CONSTITUTION:As an additive to a nonaqueous solvent, a nitroalkane is used which is represented by the general structural formula: CnH2n+1-NO2 wherein (n) is a natural number from 2 to 6. A solvent comprising a propylene carbonate with nitroethane added thereto in a volume mixing ratio of 10% and with 1M of LiCIO4 dissolved therein is used. A cell using nickel as a working pole and lithium as the opposite pole and a reference pole is fabricated, and electrochemical lithium is precipitated and dissolved on the nickel electrode. The efficiency of charge and discharge is calculated from the ratio of the amount of electricity required to vary the potential of the nickel electrode and to precipitate the lithium to the amount of electricity required to discharge lithium ions. The use of the above electrolyte 5 enables high voltage resistance and the charge and discharge efficiency of the negative electrode 3 to be enhanced.

The coefficient and the degree number of the n-degree polynomial which approximates the contour are coded 39 and stored as the compression data. This compression data is decoded 41 by a decoder, and a desired contour signal is restored 42.

Title: Video printer
Inventor: KUBOTA KAZUFUMI
IPC: H04N1/40
Filed: 1988-07-22
Abstract: PURPOSE:To prevent a boundary portion of division blocks from being a conspicuous eyesore even when a printed image is warped by distortion of a CRT and a printing lens, by exposing in an overlapping manner an edge portion connecting divided areas of an original picture, giving a density gradient in accordance with said distortion of the CRT and printing lens to said edge portion, so that said edge portion has approximately the same density as the other portions. CONSTITUTION:An inputted picture signal is converted to a digital signal, stored in a total image memory unit 22, and read out by an area selecting circuit 23. For example, when an area corresponding to a division block F11 is to be read out, the area added with an additional area AD11 at an edge portion thereof is read out. Therefore, a rectangular area indicated by an exposing CRT is longer in a lateral direction by the length of the additional area AD11 than the area obtained when the total image is divided into matrix. A density compensating circuit 23A of an edge portion changes, in accordance with the ratio of length in a connecting direction between the overlappingly-exposed portion due to the distortion of the CRT 10 and a printing lens 14 of the additional area AD11 among the read image data and the additional area AD11, the image density of the additional area AD11. The density gradient is changed by the shape of distortion of the CRT 10 and printing lens 14.
