IPC: F25D11/00
Filed: 1988-03-04
Abstract: PURPOSE:To obtain a highly economical cold accumulation type cold-keeping storeroom without the need for other heating elements by disposing a heat accumulator for accumulating heat radiated from capacitors on the side wall surface of the cold-keeping storeroom accommodating therein a cold accumulating agent and by heating the cold insulating room with heat from the heat accumulator when an external air temperature is low. CONSTITUTION:On the ceiling-plane of a cold-keeping storeroom body 17 is equipped a cooler 21 consisting of a cold accumulating agent 23 and a cooling pipe 24 that cools and freezes this cold accumulating agent 23. On the other hand, a heat accumulator 27 is closely fixed on the side surface part of the cold-keeping storeroom body 17. Heat accumulating capacitors 34 are disposed inside the heat insulating wall correspondingly facing the heat accumulator 27, and only when an external air temperature is low, a flow path is changed over to supply hot gas from main capacitors 36. In this arrangement, heat can be accumulated simultaneously with a cold accumulating operation when an external air temperature is low, and hence an article can be prevented from freezing without using other heating elements such as a heater.

Title: Electric power supplying system
Inventor: SENGOKU NORIO
IPC: G06F1/26
Filed: 1983-03-30
Abstract: PURPOSE:To make the supply voltage to each package almost uniform, by setting the number of electric power supplying routes from a platter to each package through a connector in accordance with the load current of each package. CONSTITUTION:Plural packages 14A-14C are connected with a platter 10 through a connector 12. Each pin 16 of the connector 12 becomes a logical signal path between the platter 10 and package 14 and the electric power supplying path from the platter 10 to the package 14. At this time, the number of electric power supplying paths (number of the pin of the connector 12 arranged for supplying electric power) from the platter 10 to each package is set in accordance with the load current of each package. Since the number of electric power supplying routes is set in this manner, voltage drops at each connector 12 can be uniformized. Therefore, the supply voltage to each package 14A-14C can be made almost uniform.

Title: Rotating machine with viscous resistance applying device
Inventor: NAKAGAWA HIROSHI
IPC: B23Q5/56
Filed: 1986-03-12
Abstract: PURPOSE:To apply viscous resistance for a rotor effectively so as to rotate the rotor smoothly, by connecting a viscous fluid pump which interlocks via an interlocking means to the rotor which is driven by a rotor driving means. CONSTITUTION:A rotary table 1 which is rotatably supported on a supporting rest 4 is driven and rotated by a servo motor 3 via a ring gear 2 and a pinion 2'. The rotation axis 1a of the rotary table 1 is connected to the rotation axis 13 of a gear pump, so that a gear pump 7 rotates in accordance with the rotation of the rotary table 1. When the gear pump 7 rotates, oil is sucked in through a pipe 14 or a pipe 15, and discharged into a tank 12 through the pipe 15 or the pipe 14 at a pressure which is set by a pressure adjusting valve 8. The rotation torque of the gear pump 7 which is generated on that time becomes viscous resistance so as to load the rotation of the rotary table 1. As this result, minute rotation unevenness of the rotary table 1 is absorbed, so that rotating actions can be carried out smoothly.

IPC: B23K9/06
Filed: 1982-03-30
Abstract: PURPOSE:To obtain an arc welding machine which is capable of remote-controlling various welding conditions from a place being at hand of a worker, by connecting a signal generator for outputting (n) kinds of selectable signals, in series to a contact of a switch for instructing welding start, wire feed, gas flow-out, etc. CONSTITUTION:Before welding is started, a worker selects a signal generator 2 suitably, and sets it so that a specified signal among (n) kinds of signals can be outputted. An output of this generator is not transferred to a discriminating circuit 5 until a switch 1 is depressed, but when the switch 1 is depressed, one among (n) kinds is discriminated by the circuit 5 through a cable 3, and its discrimination result is outputted to a welding condition setting circuit 6. On the other hand, in case of starting the welding, when the switch 1 is depressed and closed, an output of the circuit 2 is provided to an input terminal of a starting circuit 4, too. Subsequently, the circuit 4 detects a variation of this input signal, supplies a start signal to a welding condition control part 7, and the control part 7 controls an output by an output signal of the circuit 6, corresponding to a signal discriminated by the circuit 5, and executes welding.
