Title: Closed scroll compressor
Inventor: HIROOKA KATSUMI
IPC: F04C18/02
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce the distance of contact between an O-ring and the inner periphery of a main body to prevent damage of the O-ring when inserting the fixed scroll fitted with the O-ring through its upper opening by increasing the inside diameter of the main body portion upward of the portion in contact with the O-ring to be larger than that of the portion in contact with the O-ring. SOLUTION: In this closed scroll compressor, a scroll compressor mechanism C is housed in a closed housing 8 having a body 8a and an upper end plate 8b welded to the upper end thereof. The closed scroll compressor is formed by pressing the outer periphery of a fixed scroll 1 of the scroll compressor mechanism C to be in contact with the inner periphery of the body 8a via an O-ring 89. Also, the inside diameter of the upper portion of the body is increased to be larger than that of the portion where the body contacts with the O-ring 89 by expanding the upper portion of the body 8a. By this structure, when inserting the fixed scroll 1 fitted with the O-ring 89 by burying into the body 8a through the upper opening, the distance of the contact between the O-ring 89 and the inner periphery of the body 8a is reduced, thus preventing damage of the O-ring.

Title: Terminal metal fitting
Inventor: TANAKA TSUTOMU
IPC: H01R13/533
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To enhance a slight-slide preventing effect. SOLUTION: A joint part 17 extending in a fitting part 11 and adapted to be elastically deflectable by being bent substantially in a V-shape so as to cross the advancing/retreating direction of a male tab T is formed on an upper wall 14 (wall plate) of the fitting part 11, and an elastic contact piece 18 is formed joining to a front end of the joint part 17. When the male tab T is slightly moved reciprocatingly in the advancing/retreating direction due to vibration or the like, the elastic contact piece 18 is slightly moved reciprocatingly following the male tab T because of the elastic deflection of the joint part 17, and therefore no slight slide occurs between the male tab T and the elastic contact piece 18.  The joint part 17 is easily deformed because it is bent in a direction crossing the advancing/retreating direction of the male tab T, and therefore it is excellent in the function of preventing slight slide.

Title: Method for discriminating spiral axis in cholesteric medium
Inventor: NISHIMURA RYO
IPC: G01N21/21
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To simply discriminate the direction of a spiral structure by discriminating the direction of a spiral axis of a cholesteric medium according to a difference in quantity of light transmitted and reflected from right and left circularly polarized light areas by use of one circular polarization plate where right and left circularly polarized light transmitting areas exist. SOLUTION: Two λ/4 plates are stuck to each other in such a manner as to share common boundary with each other on a linearly light polarizing plate. The axes are arranged in such a manner that the axis of the two λ/4 plates intersect perpendicularly to each other, the transmission axis of the light polarizing plate is arranged at 45 degrees to the respective axes of the λ/4 plates, and the plates are stacked through a pressure sensitive adhesive agent. Thus, the left side is a left circular light polarizing plate and the right side is a right circular light polarizing plate. Light transmitted to be reflected by the cholesteric medium is observed through the right and left circular light polarizing plates to determine the torsional direction of a screw structure of the cholesteric medium from the quantity of light for a light source.  That is, in the case where right or left circularly polarized light is incident, there is a difference in quantity of transmitted light transmitted through right and left circular light polarizing plates. Such contrast is observed to simply determine the torsional direction.
