IPC: F28D20/00
Filed: 1994-02-08
Abstract: PURPOSE:To take out a high latent heat and repeatedly use the heat accumulating device for a long period by a method wherein a heat accumulating material is filled at a clearance between a cylindrical container and a cylindrical hollow core member and a heater is installed at a hollow part of the cylindrical hollow core member. CONSTITUTION:An ellipse cylindrical hollow core member 15 is arranged in an ellipse cylindrical container 2 in such a way that its axis may coincident with its central axis and than long axis directions of the ellipse sectional shapes may be crossed to each other at a right angle. A planer heater 17 having the substantial same length as that of the cylindrical hollow core member 15 is installed at a hollow part 16 of the cylindrical hollow core member 15. The maximum value D1 of a distance in a diameter direction of an inner circumferential surface 9 of the cylindrical container and an outer circumferential surface 13 of the cylindrical hollow core member is preferably 5 to 25mm. Then, heat accumulating material 3 is filled at a clearance 11 between the cylindrical container 2 and the cylindrical hollow core member 15. As the heat accumulating material 3, composition of sodium boric acid 10 liquid salt and sodium sulfuric acid 10 liquid salt is preferably applied. Sodium boric acid 10 liquid salt becomes a core of crystallization during cooling of the heat accumulating material and then fine crystallization of sodium sulfuric acid 10 liquid salt can be promoted and a supercooling phenomenon can be restricted.

Title: Compressor
Inventor: MARUYAMA TERUO
IPC: F04C28/24
Filed: 1981-02-03
Abstract: PURPOSE:To enable to open and close a valve for opening and closing an intake passage of a compressor by the function of a shape memory alloy, by detecting the temperature of intake fluid correctly through provision of a heat-insulating material or a hollow space between the shape memory alloy and the intake passage. CONSTITUTION:A rear case 13 and a valve case 15, formed at the section incorporating a coil spring 16 made of a shape memory alloy, are kept apart from each other by the intermediary of a hollow space. One end face of the coil spring 16 is supported by a heat-insulating material 22 while the other end face is supported by a spool 17. Here, since the coil spring 16 detects only the temperature of intake cooling medium and causes expansion and contraction with high accuracy, being not influenced by hot discharge gas filled in the rear case 13, a valve in an intake passage 23 can be opened and closed at a proper timing.

Title: Vibration attenuation device for building frame
Inventor: MIURA YOSHIKATSU
IPC: F16F15/023
Filed: 1993-02-01
Abstract: PURPOSE:To attenuate vibrations by wind due to building frames or earthquakes. CONSTITUTION:A wire is used as a brace in a plane of structure comprising beams and posts and both ends of the wire are connected to the cornered parts of the other plane of structure by way of a roller 4 installed to the cornered part of each plane of structure. A viscous damper 5 is fixedly mounted to a part of the wire while the other side of the damper 5 is fixed with a beam 2 which constitutes the plane of structure. More specifically, the deformation of a frame is reduced by exerting attenuation performance with plastic deformation attributable to plane deviations delta between the side of the brace 3 of the damper 5 and the side of the beam 2 produced when the plane of structure is subjected to deformation by an earthquake or the like, thereby attenuating the vibration of the building.

Title: Optical element evaluating method
Inventor: FUKUDA YUSUKE
IPC: G01B11/24
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To measure transmission wave fronts without using a reflecting mirror such as a return spherical mirror by using an aplanatic lens. SOLUTION: In an aplanatic lens 12, an object of measurements, incident spherical waves 109 are internally converted into a predetermined wave front by a first surface (R1 surface) 102 and are internally transmitted, and a second surface (R2 surface) 103 is created so as to have the function of a return mirror. In other words, the curvature of the R2 surface is determined by the wavelength of a measuring light beam, the refractive index of the glass material of a aplanatic lens 12, each curvature of the R1 surface 102 and a Fizeau surface, etc. By utilizing these characteristics, a measuring light beam emitted from the Fizeau surface 101 is transmitted through the R1 surface 102, reflected by the R2 surface 103, transmitted through the R1 surface 102 again, the returned to the Fizeau surface 101 at the same angle as that in the emission.  By using these characteristics and correcting data on the shape of the R2 surface 103 and data on spherical aberration which occurs in the aplanatic lens 12, it becomes possible to evaluate transmission wave fronts by spherical waves without using a return mirror.

Title: Optical device
Inventor: MIYAWAKI MAKOTO
IPC: G03B17/28
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To simply constitute a maloperation preventing mechanism preventing the light shielding door of a film cartridge from erroneously opening in the feed mode of a film so as to miniaturize it by providing the maloperation preventing mechanism driving a member obstructing the operation of a cover opening/closing operation member by using friction force of a gear as a drive source. SOLUTION: A drive gear 2 is rotated anticlockwise during winding a film and at photographing after winding, a lock lever 4 is also turned anticlockwise by the friction force due to the rotation, it is put in the cutout part of a closing lever 9, and hence the turning of the closing lever 9 is obstructed. Consequently, even when an operation part is operated by mistake at this time, a door driver is not turned in the closing direction by the mechanism obstructing the turning of the closing lever 9, and hence an accident pinching a film with the light shielding door of a cartridge is prevented. Namely, a mechanism locking an operation lug with the lock lever 4 turned by friction force generated by the turning force of the gear 2 except rewinding can be constituted with a few number of parts.

Title: Sheet material delivery mechanism
Inventor: MATSUMOTO HIROAKI
IPC: H04N1/00
Filed: 1985-01-31
Abstract: PURPOSE:To enables a document and a recording material to be smoothly delivered onto the same tray, by a method wherein, when duplication is effected by a facsimile and the like, the rear end of a lowermost sheet material to be delivered is detected by a sensor, and after the lowermost sheet is delivered a sheet material adjacent to the delivered underlaying sheet is delivered. CONSTITUTION:When duplicating motion is effected, delivery of a document 2 is stopped until the rear end of a recording paper 17 is detected by a recording paper end part detecting sensor 23, and after the rear end of the recording material 17 passes the position of the sensor 23, the document is delivered by a document delivery roller 10. This, after the recording material 17 is delivered and dropped onto a delivery tray 12, causes the document 2 to be delivered and dropped. In which case, in case several documents 2 are continuously duplicated, a distance L1 between a reading point 9 and the document delivery roller 10 is decreased over a distance L1 between a recording point and a recording material delivery roller 21, and this enables a first document 2 to be completed in delivery before the forward end of the second recording material 17 is delivered onto the delivery tray 12. This causes the recording material 17 and the document 2 to be alternately delivered to the tray 12.
