Title: Pitch-impregnation treatment of graphite electrode
Inventor: IMAI MASANORI
IPC: C01B31/04
Filed: 1990-01-16
Abstract: PURPOSE:To effectively prevent loss of working hours and heat by loading calcined electrode materials on a stuffing-basket truck, conveying the materials to a heating tank and to a pitch-impregnating tank, carrying out impregnation, subsequently transshipping the impregnated electrode materials into another truck for next process, cleaning the empty truck and subsequently recycling the cleaned truck. CONSTITUTION:In a pitch-impregnation process composed of loading of calcined electrode materials on a stuffing-basket truck, conveying of the materials to a heating tank and an impregnating tank and transshipping of the impregnated electrode materials into another truck for a tunnel kiln, a cleaning material is applied to an empty truck after transshipping of the impregnated electrode materials into the truck for a tunnel kiln to remove sticking pitch. The calcined electrode materials are loaded on the cleaned empty truck and successively conveyed from the heating tank to the impregnating tank by the same truck. By the above- mentioned method, the stuffing-basket truck having the calcined electrodes loaded and heat- treated in the heating tank can successively be transferred to the impregnating tank while leaving the track as it is and impregnation of pitch can be carried out. Accordingly, different stuffing-tracks are not required for heating and for impregnation unlike the conventional method and transshipping of the electrode materials are not required between both the processes therefor, thus realizing effective prevention of loss of working hours and heat.

Title: Semiconductor storage device
Inventor: TOYOMOTO HIDEHARU
IPC: G11C16/06
Filed: 1985-01-18
Abstract: PURPOSE:To obtain a storage which is integrated to a large degree by applying one electrode with a high potential in writing operation and with an intermediate potential in reading operation and also applying the other electrode of an FAMOS element which is applied with a control signal at a control electrode with the ground potential in the reading operation and with a constant potential between the intermediate potential and ground potential in the writing operation. CONSTITUTION:When the reading operation is performed, a power source 1 is at the intermediate potential 5V, a signal line phi is at 5V, and phi' is at 0V; and the output of an inverter 23 is 0, N-ch MOS28 is on, and outputs of inverters 14 and 17 are at 5V and 0V respectively, so that N-ch MOS22 turns off. The current amplification factor of an FET24 is increased and a contact 11 is held almost at 0V, thereby reading the drain voltage of an element 10 which indicates storage out of a sense amplifier 27 accurately. When writing operation 1 is performed, the power source 1 is at 21V and phi and phi' are at 0 and 5V respectively, and the element 28 is off. Further, phi1-phi4 area at 21V and elements 7-10 turn on; and the source-drain potential difference of the element 10 becomes smaller to suppress a leak and a punch-through through phenomenon. Consequently, normal writing operation is performed even when the channel of the FAMOS is shortened for high integration.

Abstract: PURPOSE:To enhance the efficiency of a solar heat collector, by a heat-collecting system wherein heat exchange at a solar heat collector is effected mainly by exchange of latent heat. CONSTITUTION:A reserving tank 9 is provided with an upper liquid level detecting means 10 and a lower liquid level detecting means 11 which are provided at heights intermediate between the uppermost part and the lowermost part of the solar heat collector 1. When the liquid level in the tank 9 reaches a preset lower liquid level, the detecting means 11 detects the liquid level, a pump 4 is started to operate by passing an electric current thereto through a controller 7, and a latent heat type heat-transmitting medium condensed in a heat exchanger 3 is fed to the tank 9. When the liquid level in the tank 9 reaches to a preset upper liquid level, the detecting means 10 detects the liquid level, the passing of the electric current to the pump 4 is stopped through the controller 7, thereby stopping the operation of the pump 4. Accordingly, the liquid level of the medium in the solar heat collector 1 is maintained at the level preset in the tank 9, and in the collector 1, heat is collected at a high efficency mainly through exchange of latent heat accompanied by conversion of the medium from a liquid to a vapor.
