Title: Frame step out prevention system
Inventor: SHIMOYAMA TSUNAYOSHI
IPC: H04L7/08
Filed: 1978-12-29
Abstract: PURPOSE:To prevent frame step out by delaying one output of two-system transmission circuits and rearranging their outputs according to a fixed rule and transmitting them and by delaying the output of the other circuit similarly to transmission and rearranging them reversely to transmission in the receiving side. CONSTITUTION:The output of transmission-side carrier-frequency terminal equipment 11 is subjected to bipolar/unipolar conversion and series-parallel conversion in bipolar/unipolar converter 12 to generate two-system PCM pulse trains PCM1 and PCM2. One pulse train PCM2 is delayed by proper number n of bits in a delay circuit to generate pulse train PCM2'. After that, two-system signals are rearranged according to a fixed rule in 14-1 and 14-2 and are transmitted. Meanwhile, in the receiving side, two-system signals are rearranged reversely to the transmission side by 21-1 and 21-2 after the other pulse train is delayed by the same delay quantity as the transmission side in 22. As a result, error bits in the demodulation signal can be dispersed to prevent frame step out.

Title: Pattern formation
Inventor: YAMAGUCHI ATSUMI
IPC: H05K3/02
Filed: 1988-07-01
Abstract: PURPOSE:To prevent the deterioration in the sensitivity of resist thereby forming even patterns by a method wherein a metallic wiring film in high diffusion reflecting power is formed on an insulating film and after forming resist patterns on the metallic film, a specified metallic wiring pattern is formed. CONSTITUTION:A metallic wiring film 2 is formed on an insulating film 1 by bias sputtering process. The metallic wiring film 2 made of Al is provided with high photoreflecting power so that an incident light may be divided into positive reflected light B and diffused reflected light C thus the higher the flatness in the underneath layer the larger the positive reflecting component but in reverse, the lower the flatness, the larger the diffusion reflecting component. Next, after coating the metallic film 2 with a resist film 4, resist patterns 6 are formed by irradiating the incident light A through a mask 5 and then developing the resist patterns 6. The metallic wiring film 2 in high diffusion reflecting power is subjected to narrower amplitude compared with the other metallic wiring film formed by ordinary sputtering process. Through these procedures, the fluctuation in pattern dimension caused by the fluctuation in thickness of the resist 4 in case of development can be reduced compared with the fluctuation by the sputtering process.

IPC: H01M4/88
Filed: 1986-07-16
Abstract: PURPOSE:To increase current collecting function by forming a cylindrical cloth or knit with fiber bundle of fire resistant fiber which is precursor of carbon fiber, and carbonizing the cloth or knit by heat treatment in a nonoxidizing atmosphere. CONSTITUTION:A cylindrical fiber bundle of fiber which is precursor of carbon fiber such as polyacrylonitrile fiber, cellulose fiber, and pitch fiber which forms carbon fiber by fire resistant treatment and carbonizing process is heated at 150-400 deg.C in an oxidizing atmosphere without combustion to give fire resistant property. In the fire resistant treatment, although heat reserve phenomenon arrises, since fiber bundle is used, a large amount of heat reserve is not appeared compared with use of cloth or knet, and run away reaction can easily be retarded. The fiber bundle in which unit fiber diameter is 3-20mum, and the number of unit fibers is 1,000-24,000 is preferable so that a thick product can be obtained. Thereby, current collecting function is increased and internal resistance is decreased.

Abstract: PURPOSE:To prevent defective travelling from occurring due to distortion of film even in a printing device which uses high printing pressure by making value of elastic modulus of a base film to be above a specific value, in a film ribbon constituted of a base film made of synthetic resin coated with ink. CONSTITUTION:A film ribbon 1 is constituted of an ink layer 4 made of a base film 5 coated with ink. For the base film 5, polyethylene terephthalate (PET) with a thickness of 6mum is used, and elastic modulus is adjusted by controlling drawing condition or molecular weight of material high molecule. The adjustment is performed until PCS (index of printing density) becomes 0.2 or less avoiding generation of defective travel, that is, the adjustment is performed so as to make the elastic modules become 7kg/mm<2> or above. Also, when polyethylenenaphthalate is used as a material of the base film 5, the same elastic modulus can be obtained even with a thickness of 5mum. Thus, the ribbon is prevented from distorting between a ribbon outlet 2 of an endless type ribbon cartridge and a head 3.

Inventor: SUZUKI KATSUYUKI
IPC: B23B51/00
Filed: 1995-06-30
Abstract: PURPOSE: To improve sharpness at cutting and flow of chips and prevent clog ging of chips by making a helix angle of a chip discharge groove in a region of a tip side constant and reducing the helix angle gradually toward the direc tion of a basic end in a region of a rear end side which follows the region of the tip side. CONSTITUTION: Since a helix angle of a chip discharge groove 7 is set to be constant in a region La of a tip side of a tool main body 2, even a tool made of stainless steel which cannot machine easily as well as a tool made of ordinary steel provide sharp cutting by increasing a rake angle of a cutting blade, and hole precision such as expanded allowance at an inlet of an object to be cut is good. Furthermore, the helix angle is gradually reduced in a region Lb of a rear end side and is set to a larger angle than 0 deg. in a groove cut-up section to improve chip discharge property and prevent clogging of chips. By making the thickness of a core in the region Lb of the rear end side where the helix angle is gradually reduced smaller than that in the region La of the tip side, it is possible to ensure a chip discharge space and suppress clogging of chips in this region.
