Title: Data changing device for read only memory
Inventor: KUMASAKA HIDEYUKI
IPC: G06F9/06
Filed: 1981-07-10
Abstract: PURPOSE:To change a part of a program in ROM simply by outputting changed data that substitute for prohibited data to a data bus line when a readout prohibiting device prohibits data readout of ROM. CONSTITUTION:A CPU 1 reads out data stored in designated address through a bus line 4 while designating readout address of an ROM 3 through an address bus line 2. A readout prohibiting device 5 sets a specified address of the ROM 3 that requires change, and at the same time, prohibits data readout of the ROM 3 only when the set address coincides with a readout address by the CPU 1 inputted through the bus line 2. At this time, a changed data outputting device 6 outputs the changed data set by a switch in place of the ROM 3. By this way, apparently the same effect with the case where a part of a program of the ROM 3 is changed can be obtained.

Title: Dry evaporator
Inventor: MASUDA KIYOSHI
IPC: F25B39/02
Filed: 1991-05-13
Abstract: PURPOSE:To provide a dry evaporator with good efficiency in heat-exchanging performance available at a low cost by using cooling tubes which function at an optimal heat-transfer rate in dealing with the changes in state of the refrigerant flowing through a refrigerant circuit. CONSTITUTION:A channel for refrigerant passed through a shell 1 is formed of a ripple-finned tube 5, which has spiral groove 52 cut inside, on the side of the inlet and of an inner-finned tube 6, which is provided with inner fins 62 inside, on the side of the outlet. In the region where the refrigerant becomes a slag flow and a vapor flow in the form of rings, the groove 52 accelerates the boiling of the refrigerant and collects the atomized particles that the boiling produces in the vapor flow so that the overall heat-transmission coefficient is improved. In the region where the refrigerant dries out and turns from a vapor flow to a single-phase vapor flow, that is, on the side of the outlet of the refrigerant channel, the refrigerant undergoes exchange of heat with liquid to be cooled through the inner-finned tube 6 whose area effective for the exchange of heat per unit length is large. Thus by putting a ripple- finned tube 5 and an inner-finned tube 6 to effective use in heat-transfer rate on the side of refrigerant a dry evaporator can be made available at a low cost relative to improvement in the heat-exchange efficiency.

IPC: C25D7/04
Filed: 1978-09-01
Abstract: PURPOSE: To prevent current concentration in pipe end parts and obtain uniform thickness of plating, by connecting or inserting a different metal pipe which is electrically conducting with the metal pipe into the both ends of the metal pipe, and electroplating the inner wall of the pipe.  
     CONSTITUTION: A copper wire 9 to plated is inserted into the central line of a zircaloy pipe 1 for covering nuclear fuel by means of plastic jigs 3, 4, and metal pipes 10 of at least 10 mm (variable with the inside diameter of the pipe 1) are connected or inserted into the both ends of the pipe 1. Circulating specified copper cyanide solution through inlet 6 and outlet 7, electroplating is appled by using the copper wire 9 as the anode and the pipe 1 as the cathode. Thus, causing the unevenness of plated layer attributable to concentration of the current on both ends parts in the inner wall of the pipe 1 in the pipe 10, a plated layer of uniform thickness is formed on the inner wall of the pipe 1.
