Title: Scroll type compressor
Inventor: KAWABE ISAO
IPC: F04C18/02
Filed: 1992-09-10
Abstract: PURPOSE:To stably press a fixed scroll vane against a revolving scroll despite of the change of a pressure by forming at least three pressure introduction chambers on the back side of the fixed scroll vane and introduction gases to be compressed, having pressures different from each other, to each chamber. CONSTITUTION:After refrigerant gas is sucked in a first compression space a1, the refrigerant gas is compressed through reduction of the volumes of compression spaces a1-a3 by means of a revolving scroll vane 11. In this case, a part of refrigerant gas is introduced to pressure introduction chambers 38-40 from the compression spaces a1-a3 through pressure introduction holes 31-33. The pressure of refrigerant gas is exerted on the back surface 31 of the fixed scroll vane 12. In which case, since the pressure of the refrigerant pressure is increased along with movement of it to the central sides of the two scroll vanes 11 and 12, refrigerant gases having pressures different from each other are introduced to pressure introduction chambers 38-40. A back pressure exerted on the fixed scroll vane 12 is gradually increased toward the central side of an end plate part 12a. As a result, contact between the two scroll vanes 11 and 12 is stabilized.

Title: Tape cassette
Inventor: SHIMA MOTOHIKO
IPC: G11B23/087
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To stably operate a reel brake by making a case wall thickness of the part encircled with the rib part provided in the zone separating from the gate position of the case and moreover coming into contact with a back surface side wall thinner than the other case wall thickness. SOLUTION: The gate position 30 is provided in the side wall part 31 of the case front surface side in an upper case 3a. Guide ribs 31, 32 guiding a reel brake member, a rib 33 for a memory element housing part and a rib 34 for dividing a tape reel area are provided in the case back surface side. The case wall thickness of each guide rib periphery is made to be thinner than the other case wall thickness. Since the gate 30 of the upper case 3a is provided in the front surface side of the case, shrinks are easily generated in the outer surface of the case in the vicinity of guide ribs 31, 32 remote from the gate. Therefore, the wall thickness of the zone part divided with respective ribs 31, 32, 33, 34 is made to be thinner than the other part so as not to generate shrinks.  Further, although the rib 34 of a reel area dividing wall exists in both end part of the back surface side, shrinks are not generated because ribs are not clustered here.

Title: Heat accumulator
Inventor: KANEDA TATSUZO
IPC: C09K5/06
Filed: 1985-10-30
Abstract: PURPOSE:To maintain a supercooled gel state of a heat accumulating medium and to enable utilization of heat with certainty when necessary, by providing at the vapor-liquid interface of a specified heat accumulating medium a liquid composition which prevents the contact of the heat accumulating medium with a vapor phase. CONSTITUTION:The evaporation of the moisture of a heat accumulating medium 2 into the air is prevented by a liquid composition 5 (e.g., an oil film) provided at the vapor-liquid interface of the heat accumulating medium 2 containing a salt which undergoes reversible phase transition between a more hydrated gel phase and a less hydrated crystal phase with evolution or absorption of latent heat (e.g., hydrated sodium acetate containing 41wt% water). Therefore, the formation of crystals of the medium 2 at the interface will not take place, and the medium 2 will maintain its supercooled state stably even if the tempera ture decreases so that heat accumulation can be effected with certainly. When heat is needed, a heat generating unit 4 is operated to move its pointed end through the composition 5 into the medium 2, which is thereby stimulated to form nuclei and to be crystallized wholly in a short time. This phase transition yields a latent heat, which is transmitted to cold water running in a pipe 3.

CONSTITUTION:Each synthetic lens 12 is provided with synthetic lens structure of a refractive index distribution lens part 12A formed in the inside of the substrate and a convex lens part 12B formed by protruding the surface in a constant range from the central axis of the lens part 12A in a smooth circular arc curved surface. The maximum refractive index is attached on the convex lens part 12B, and the refractive index of the refractive index distribution lens part 12A is gradually reduced advancing to a radiating direction cetering that part. Therefore, incident light on the projecting curved surface 12B of the lens is refracted at a curved surface in a focusing direction, and also, it is refracted at a lower refractive index distribution area additionally. In such a way, it is possible to increase the light focusing angle theta of a plane micro-lens, and to obtain a large numerical aperture (NA) value.
