IPC: B65B27/00
Filed: 1993-12-27
Abstract: PURPOSE:To miniaturize and simplify the structure with the number of component parts reduced by a method wherein a sliding base makes, as it advances, a bent member turn and squeeze in when a binding cord is pressed against the circumference of articles to be bound and squeezed in with a hook-like hand.

Title: Image coding decoding system
Inventor: OKITSU HIROMI
IPC: H04N19/20
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To attain high efficiency coding without reducing the coding efficiency as to a synthesis image frame where a synthesis ratio of preceding succeeding frame ratio is not 1:1. SOLUTION: Image information of an object frame to be coded and its preceding and succeeding frames is normalized by an edge extract section 42 and an edge normalizing processing section 43. Whether or not an object frame is a synthesis frame is discriminated based on a difference of contrast between a normalized edge image of the object frame and a synthesis normalized edge image by preceding and succeeding frames. A picture element value of the normalized edge images of the object frame and its preceding and succeeding frames is integrated as to a range specified by the normalized edge images of the object frame and its preceding and succeeding frames is integrated and the synthesis ratio of the object frame is introduced. A synthesis ratio introduction section 53 provides an output of a synthesis ratio when the object frame is discriminated to be the synthesis frame and image information of the object frame is coded accordingly.

Abstract: PROBLEM TO BE SOLVED: To manufacture a jointed body of an electrolyte layer and an electrode having a sufficient gas permeability and conductivity. SOLUTION: A needle-shaped pore forming material is formed from iron (S100). This material is dispersed in a solvent along with carbon fine particles carrying catalysts to make paste ink (S110), and to form a sheet electrode forming member (S120). The formed electrode forming member is dried in such a state that a magnetic field perpendicular to a sheet face is applied (S130), and the dried electrode forming member is pressed to both sides of an electrolyte film by means of hot pressing (S140). A jointed body obtained in this way is boiled with dilute sulfuric acid to effect elution of the pore forming material (S150), and a power generation layer is finished as the jointed body between an electrode and the electrolyte film. Since a plurality of fine pores oriented perpendicular to the surface in the lengthwise direction are formed in the electrode of the power generation layer, the electrode possesses sufficient gas permeability and conductivity.
