IPC: B66B13/14
Filed: 1990-03-12
Abstract: PURPOSE:To improve operation efficiency by providing a door open time extending means which maintains a door open state for a specified time by controlling a door opening/closing means even if operation of a door open button is suspended when a person recognizing and identifying device identifies a passenger as a specifically registered passenger, when the passenger operates the door open button. CONSTITUTION:When a door open button 1 is pressed while an elevator is stopping, the door is opened if the door is closing. Then a fingerprint is detected by a fingerprint detector 4 and checked by a fingerprint checking device 5, and if the fingerprint is identified, a door opening/closing control means 2 is controlled to extend door open time and indicates that the door open time is to be extended. Then time since the door open button 1 is released is counted, an indicator lamp 7 is put out, a buzzer 8 is sounded to inform that the door is to be closed and then the door is closed. If the fingerprint is not identified, the door remains open while the door open button 1 is being pressed and the door is closed when the button is released. Thus unnecessary extension of the door open time is eliminated.

Abstract: PURPOSE:To improve durability and heat-resisting performance of a solar-heat collecting plate, by forming a baked and hardened film of a mixed paint obtained by mixing a black pigment to a paint of polyether sulfon resin over the surface of a solar heat collecting plate. CONSTITUTION:A baked and hardened film of a mixed paint obtained by mixing a black pigment such as carbon black to a paint of polyether sulfon resin is formed over the surface of a solar-heat collecting plate. In applying the above film over the surface of the solar-heat collecting plate, a mixed paint for selective absorption of black color, containing 10% of solid is at first prepared, for instance, by adding 30g of a black pigment to 100g of the paint of polyether sulfon resin and diluting it with an organic solvent after agitating the kneading the same uniformly. Then, a heat collecting selective absorption film having a thickness of 3-5mu is formed by applying the above mixed paint over the surface of a heat collecting plate made of aluminum and baking and hardening the same for 10-20min at a temperature of 200-300 deg.C. The film thus obtained stands long use under a temperature lower than 250 deg.C and is advantageous in that it does not cause heat deterioration and the thickness of the film can be further reduced. Further, it is excellent in its corrosion-resisting and weather- resisting performance.

Title: Fuel assembly
Inventor: SANO HIROKI
IPC: G21C3/30
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce the number of uranium fuel rods containing a combustible poison in a reactor core loaded with MOX fuel without lowering the fuel economy by increasing such an element that has larger absorbing sectional area of neutron in terms of isotopic composition ratio in the combustible poison. SOLUTION: A fuel assembly 1 consists of a channel box 2, a fuel rod 3 in which a gadolinium is added to an enriched uranium, an MOX fuel rod 4 in which a natural uranium is enriched with a plutonium, and a water rod. The gadrium used for the fuel rod 3 contains Gd-155 and Gd-157 two times those included by about 15% in natural one. Thus, when compared with a case where the natural gadolinium is adopted, the number of uranium fuel rods added with gadolinium necessary for the fuel assembly can be reduced by two pieces. Further, since the enrichment of gadolinium is not increased, it can be used as it is and the fuel economicity is hardly failed.

IPC: C25D17/00
Filed: 1980-05-10
Abstract: PURPOSE: To perform high-speed electroplating of a striplike metallic plate at low power costs by suppressing the flow of electrolyte and performing no electrolysis in the low velocity filled part at the time of ejecting the electrolyte in counter current to the surface of the traveling striplike metallic plate.  
     CONSTITUTION: Electrolyte 11 is supplied at high speeds in counter current only to the plating surface of a striplike metallic plate 6 from the nozzles 9 and nozzle holes 9' provided in an electrode 7 and electricity is conducted, whereby plating is applied. At the same time, the overflowing liquid 11 is released into the space in a tank 1. Hence, there is no deposition of plating metal on the nonplating surface of the plate 6. Further, arrangement is so made that electricity is not conducted between a member 8 for preventing the back flow of the liquid 11 provided in contact with the nozzle 9-1 positioned in the extreme rear with respect to the blow out direction out of the nozzles 9 and the plate 6. As a result, electrolytic plating does not take place in the part of the member 8 in spite of filling of the liquid between said member and the plate 6. Hence, plating of so-called "burnt deposit" does not occur in the plated surface of the plate 6, and the smooth and uniform plated surface of good adhesive strength is obtained.

IPC: B41J7/48
Filed: 1981-04-24
Abstract: PURPOSE:To attain a cheaper printer capable of performing precise printing with simplified structure by a construction wherein rotation of a motor is transmitted to a font drum via a spring clutch. CONSTITUTION:A pinion gear 25 is fixed to the distal end of an output shaft of a motor 13 and a gear 26 is in mesh with the pinion gear 25. One end of a coil spring 29 is fixed to the side of the gear 26, while a hook portion 29a at the other end thereof is engaged with a tubular member 28. Thus, when rotating force is transmitted in such a direction that the spring 29 is wound round a shaft portion of the gear 26, the gear 26 transmits the rotating force of the motor 13 to the font drum via the pinion gear 25 and the tubular member 28. By so doing, the motor 13 is continuously rotated even when the drum is stopped, thus eliminating a need of rotating the motor itermittently each when the drum is subject to intermittent rotation. As a result, it becomes possible to adopt brush type micromotors of cheaper cost.
