IPC: B65G65/46
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To secure stable transfer quantity even at low temperature by bringing a moisture-containing gas into contact with activated carbon in a supply hopper and by controlling the temperature of the powder activated carbon using the adsorption heat generated then. SOLUTION: Activated carbon received in a silo is first, transferred to a supply hopper 7. The hopper 7 is provided with a blowpipe 9 for moisture- containing gas and a temperature-detecting end 10. After the activated carbon is fluidized by fluidized air 5 and a pin thrust rod in a suction port of a powder pump 4, it is passed through a prescribed quantity space formed by a stator 1 and a rotor 2 and sent out along with the air. The temperature can be grasped by a powder temperature 8. Carrier air 3 is mixed in a pump exit and the activated carbon is carried to a prescribed part through a carrier pipe 6. When the activated carbon temperature in the hopper is 15 deg.C or less, the moisture- containing gas is blown from a flow pipe 9 so as to heat the activated carbon and maintain its temperature at a quantitatively transferable temperature.

Abstract: PROBLEM TO BE SOLVED: To facilitate the assembling, to reduce the unevenness of the reversing characteristic, and to facilitate the confirmation of continuity and non-continuity by integrally forming a coned disc spring driving piece and a coned disc spring cover with each other, and reducing the number of part items without hindering the click feeling at the time of pushing a handle. SOLUTION: When an operator pushes a handle 3, a driving projection lid pushes down a cut-and-standing part 8a, and simultaneously, a contact pushing projection 11a pushes a plate spring main body 8b. Furthermore, when a free end of the cut-and-standing part 8a abuts on a rib 2a so as to strengthen the energizing force, a driving piece 11b is moved upward so as to elastically deform supporting arms lie, 11f, and a projecting part of a coned disc spring 4 is reversed by a coned disc spring pushing projection 11c so as to generate the click feeling. At the same time, a movable contact 8d of a main body 8b contacts with a fixed contact 10a, and a push button switch is electrically continued.  When pushing of the handle 3 is eliminated, the energizing force of the plate spring 8 and the coned disc plate 4 reset the driving piece 11b to the original condition, and while the contacts 8d, 10a are opened so as to release the electrical continuity of the switch.

Title: Transmitter-receiver
Inventor: NAKAMURA MASAFUMI
IPC: H04Q9/00
Filed: 1986-12-26
Abstract: PURPOSE:To prevent useless consumption of power when there is no signal, to receive a valid signal without any lack of a part, and to prevent an erroneous action caused by beams other than a light signal beam by providing a circuit to turn on a power supply and a circuit to turn off the power supply to a second transmitter-receiver. CONSTITUTION:To the second transmitter-receiver 102 that receives a radio signal transmitted from a second transmitter-receiver 101, the power supply turning-in circuit 107 and the power supply turning-off circuit 108 are provided. In order to start the transmitter-receiver 101 to transmit a radio signal from the transmitter-receiver 102, an operator manipulates the manual input part 110 of the latter to turn on the power supply by the power supply turning-in circuit 107. Accordingly, the transmitter-receiver 102 can be ready well in time for the starting transmission in the transmitter-receiver 101, and can receive radio signals accurately from the beginning. If the part 110 is not manipulated, the power supply is not turned on, hence an erroneous action can be prevented. In case the part 110 or the transmission of radio signals from the transmitter-receiver 101 stops, since the additional information of a radio signal is no longer detected, the power supply turning/off circuit 108 cuts off power supply, and the useless power consumption when the signal is absent can be prevented.

Title: Vacuum deposition apparatus
Inventor: HATTORI SHINTARO
IPC: C23C14/24
Filed: 1987-12-04
Abstract: PURPOSE:To prevent a thin film formed on a substrate from being contaminated by providing collimators having cooling means, respectively, on a straight line connecting a substrate to be subjected to vapor deposition disposed in a vacuum vessel and an injection cell charged with vapor deposition material. CONSTITUTION:In a vacuum vessel 7, collimators 2 having cooling means, respectively, are disposed on a straight line connecting a substrate 1 to be subjected to vapor deposition and an injection cell 3 charged with vapor deposition material. When the vapor deposition material charged into the injection cell 3 is heated and vaporized in the above constitution and allowed to perform molecular motion in free directions, the molecules of vapor deposition material performing molecular motion in the directions other than the direction of the substrate 1 to be subjected to vapor deposition are allowed to collide against the cooled wall surfaces of the collimators and are allowed to adhere to the wall surfaces and captured. On the other hand, the molecules of vapor deposition material passing between the collimators without collision with the collimator wall surfaces form beam currents toward the substrate 1 to be subjected to vapor deposition. By this method, the molecules of vapor deposition material are diffused and cause no sticking to the vacuum vessel 7 and, as a result, the contamination of a thin film formed on the substrate 1 to be subjected to vapor deposition due to the sticking of the vapor deposition material can be prevented.

Abstract: PURPOSE:To bond superconducting lead wires firmly by forming a self-fusion layer of specified thickness on the surface of electric insulation coating of a superconducting lead wire and heating the superconducting lead wire while applying tension within a specific range when it is wound around a bobbin. CONSTITUTION:A superconducting lead wire 12 is applied with an electric insulation coating 16 and a self-fusion layer 17 of 5-100mum thick is formed on the insulation coating 16 thus obtaining a self-fusion superconducting lead wire 18. A bobbin 15 of a winding machine 19 is then rotated along with the self-fusion superconducting lead wire 18, i.e., a superconducting electromagnet 11, wound around the bobbin 15 in the X-direction thus winding the lead wire 18.

Title: Overcurrent passage indicator
Inventor: KONDO TAIKICHI
IPC: G01R15/14
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To provide an overcurrent passage indicator that is capable of rotating its magnet element smoothly to invert its indicator element being in the normality or abnormality indicating state precisely, when its electromagnet is excited and the core thereof is inverted in magnetic polarity. SOLUTION: While an indicator element 35 is in its normality or abnormality indicating state, engagement of an engaging element 42 adapted to rotate together with a magnet element 41 with either of a pair of stoppers 43 and 44 holds the magnet element 41 in an unbalanced state in magnetism to an electromagnet 38. When the electromagnet 38 is excited and its core 39 is inverted in magnetic polarity for the purpose of a shift of the indicating state of the indicator element 35, the magnet element 41 immediately starts to rotate from the magnetism-unbalanced position owing to the repulsive action of magnetic polarity.
