Filed: 1982-02-02
Abstract: PURPOSE:To improve the high-temperature preservation characteristic and the electric-discharge flatness of a battery by decreasing the amount of active fluorine which can oxidize potassium iodide. CONSTITUTION:An organic electrolyte battery is constituted by using a negative active material 2 made of a light metal such as lithium, and a positive active material 5 made of a carbon fluoride represented by the equation, (C2F)n. In such a battery, the positive active material 5 is either prepared from a carbon fluoride (C2F)n containing below 0.08wt% of, preferably below 0.005wt% of, active fluorine which can oxidize potassium iodide, or prepared by treating a carbon fluoride (C2F)n so that is contains below 0.08wt% of active fluorine.

Title: Disk for inspection and method for inspecting disk reproducing device
Inventor: SASAKI TATSUO
IPC: G11B7/22
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To easily identify the existence of abnormality for a disk reproducing device by dividing a small segmented area having N pieces of disk tracks into the groups of M pieces and deciding voice or video information to be the same between the groups of M pieces although it is different from each other between a plurality of small segmented areas in the same group. SOLUTION: A frequency signal is recorded in the L channel of an inspection disk so as to have regularity and to be changed in stages. That is, the frequency of a value obtained by multiplying the number 1 to 99 of a small segmented area by 100 is recorded, a frequency reproduced from this disk is measured and, by multiplying this measured value by 1/100, the small segmented area is identified. Here, the number of track small segmented areas is 99, N pieces (90 pieces) among these are divided by ten to become first to ninth groups of M pieces (9 pieces) and remaining 9 pieces of the small segmented areas becomes a tenth group. Since the small segmented areas of 1 to 99 are divided into groups of 10 pieces, even if no determination is made as to the number of a small segmented area where abnormality occurs, the position of the group is identified relatively easily.

Abstract: PURPOSE:To facilitate replacement, etc., of fuse and improve reliability and installation density of parts by opposing a box-side terminal to a braid terminal of a braid type fuse each other, and thereafter, giving an impulse to a terminal push plate. CONSTITUTION:In the inside surrounded with the frame 6 of a bottom plate 7, a plurality of box-side terminals 10 each having an electric contact piece 10a are arranged such that the contact piece 10a projects into the terminal connection window 11 of a terminal push plate 8. When an upper case 2 is engaged to a lower case 3, the braid terminal 5a of a fuse 5 is opposed to the contact piece 10a and an impulse is given to a plate 8 so that the terminal 5a and the contact piece 10a are en bloc made to conduct by a terminal push cam. The elastic pressure of the contact piece 10a of the terminal 10 does not therefore work when the fuse 5 is inserted into a fuse housing 4 so that the fuse 5 can be inserted with ease. The fuse can therefore be easily placed and displaced and also the terminals can be speedily and accurately connected or separated so that workability, reliability and installation density of parts can be improved.

Abstract: PURPOSE: To accurately obtain the distance to an object and its shape. CONSTITUTION: Slit beams emitted from a laser emission source 30 are scanned in a direction for crossing the vehicle advancing direction at the rear portion of a vehicle by a scan mirror 34 rotating at angular velocity ω. The slit beams are reflected by an obstacle 100 and the image of the reflection light is formed at CCDs which are two-dimensionally and continuously arranged in vertical and horizontal directions via a light reception lens 38. A comparator compares a voltage outputted from the CCDs with a threshold value and judges whether the image of reflection light is formed or not at the CCDs. An incidence angle ϕto the lens 38 of reflection light is stored at a ROM 18 and a microcomputer 14 obtains an emission angle θ of slit beams by counting time.  Then, the distance to the reflection point is calculated by the triangulation method based on a distance (d) between a mirror 36 and the lens 38, the emission angle θ, and the incidence angle ϕ, and at the same time the shape of an object in horizontal and vertical directions is displaied on monitors 44a and 44b.

Abstract: PURPOSE:To permit an image formation giving the same image quality as that of the printed matter of a printing machine by supplying the photosensitive layer of an exposed image forming material and an image receiving body between rollers, and then transferring the image to the photosensitive material with a nip positioned between the rollers and then by separating them from each other immediately after passing through the nip. CONSTITUTION:The photosensitive layer 4 and the image receiving body 5 are supplied between the rollers 1 and 2 in such a way that the layer 4 and the body 5 are not brought into substantially contact with each other. The layer 4 and the body 5 are brought into contact with the nip positioned between the rollers 1 and 2, and transferred, and immediately separated them from each other after passing through the nip. Therefore, the good transferring with good efficiency can be carried out, without generating the troubles about mottling and picking, etc., due to an excess heating and an excess temp. drop. Namely, the processing of the image forming material with rapidity is made possible by processing the material between the rollers 1 and 2. Thus, the simple image of a final image having the same image quality to that of the printed image, etc., can be obtd.
