Title: Cable fixing structure
Inventor: SHIBUYA MOTOI
IPC: H05K7/00
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To attach a cable to an enclosure so that the cable can be pressed against three ribs integrally molded with the enclosure by utilizing the elasticity of the cable by constituting a cable fixing structure of the ribs and the cable pressed against the ribs in a curved state. SOLUTION: Three ribs 12 are integrally formed with an enclosure 11 by molding a synthetic resin material. The enclosure 11 itself has a cable fixing function, because a cable 20 is fixed to the ribs 12 by utilizing the elasticity of the cable 20 in such a way that the cable 12 is putted in the recessed sections of the ribs 12 on both sides from the right side and the recessed section of the central rib 12 from the left side. Therefore, the cable fixing structure can be simplified without requiring any special parts and the excessive length of the cable 20 can be treated easily.

Inventor: MIYAZAKI TADASHI
IPC: H01H21/14
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To reduce resistance to the operation of moving a switch. SOLUTION: A fixed electrode 40 is attached to the case main body 21 of a circuit breaker device 10 by a bolt 50, together with a terminal 30. The terminal 30 is firmly held in place between the end face of a spacer 51 passed through the bolt 50 and a mounting base 24 by the tightening force of the bolt 50. and the fixed electrode 40 is pressed against the terminal 30 by the elastic force of a spring washer 52 through which the spacer 51 is passed, and is mounted in a position in which it can be inclined by deflecting the remaining deflection tolerance of the spring washer 52. Therefore when the fixed electrode 40 is pressed against the movable electrode 44, the inclination of time fixed electrode 40 is automatically adjusted to make smaller the sliding resistance between them, enabling a switch to be operated easily.

Title: Gas sensor and its manufacture
Inventor: IGARASHI SATORU
IPC: G01N27/12
Filed: 1994-12-22
Abstract: PURPOSE: To obtain a highly sensitive gas sensor by setting the lattice distortion of SnO2 to be not smaller than a specific value and specifying a lattice constant in a-axis direction of SnO2 . CONSTITUTION: The lattice distortion of SnO2 is set to be not smaller than 0.045. Moreover, the lattice constant in the a-axis direction of SnO2 is set to be not smaller than 0.4730nm or not larger than 0.4710nm. This type of SnO2 has generally a specific surface area of 40m<2> /g or larger and a crystallite diameter of 7.3nm or smaller. The specific surface area or crystallite diameter correctly corresponds to the sensitivity of a gas sensor. The larger the specific surface area, the higher the sensitivity. Moreover, the smaller the crystallite diameter, the higher the sensitivity. Therefore, the lattice distortion is preferably not smaller than 0.047 and most preferably 0.050 or larger. A solution of tin salt is hydrolyzed to obtain stannic acid sol or gel, which is in turn washed to remove anion impurities.  Thereafter, the sol or gel is brought into touch with a solution of ammonium halide to add halogen ions thereto. The sol or gel is then baked to obtain SnO2 . The obtained SnO2 is molded and connected with an electrode. The gas sensor is manufactured in this manner.
