Filed: 1993-07-06
Abstract: PURPOSE:To speed up compression processing by setting the size of a file assigned corresponding to one image to a constant value larger than a value corresponding to the amount of information selected as the amount of data representing the image itself. CONSTITUTION:Image files B1, B2, and B3 consist of header parts, image data parts, and 0-data parts B1a, B2a, and B3a respectively. A value 0 is written in those 0-data parts B1a, B2a, and B3a, which vary in area size according to the image data. In this case, the image file size is set constant.

Title: Circuit for monitoring the connective conditions of power transistor
Inventor: IENSU GUREEGERU
IPC: H03K19/003
Filed: 1990-06-27
Abstract: PURPOSE: To confirm an opened load, the short or shunt of the load and the overlarge leak current of a power transistor by monitoring the voltage on the power transistor and the voltage on the load covering the prescribed voltage range. CONSTITUTION: The state of the conducted power transistor is inspected by a comparator 7 via the power transistor 1. If lowering voltages in the transistor (UB-UA) are smaller than 2V, the comparator 7 generates a high level signal. Thus, a microprocessor confirms that the load 3 is normal and the transistor 1 is conducted. However, if the output signal of the comparator 7 is a low level, that is, overlarge voltage drop arises on the transistor 1, the microprocessor confirms that there is certainly the overload state or the short of the load 3 or the transistor 1 is not conducted perfectly.

Abstract: PURPOSE:To provide pulse combustion device which is excellent in durable performance, by a method wherein a bypass fuel feed passage, which does not run through a valve device, is installed, and switch valves for the valve device and the bypass fuel feed passage are mounted. CONSTITUTION:Fuel is fed through a fuel feed passage 14, and flows through a switch valve 13 to be fed to a valve device 9. In which case, fuel switch valves 12 and 12' are closed. The valve device 9 performs operation to switch the fuel to each burner so as to meet the frequency in explosion combustion of the burner, and feed the fuel to a combustion chamber 5 or 6. Burners 1 and 2 perform pulse combustion at a phase difference of 180 deg.. When, during combustion, the valve device 9 is normally interlocked, a problem rises in durability of the valve device 9. Therefore, after the device is brought into a pulse combustion condition, a switch valve 13 is closed, and the valves 12 and 12' are opened. The fuel is fed to the combustion chamber 5 or 6 through a bypass fuel feed circuit 10 or 11, and each burner continues to effect combustion at a phase difference of 180 deg.. After the fuel is switched to the bypass fuel feed circuit, a valve device is brought to a stop.

Title: Cache memory controller
Inventor: SANBE TAKESHI
IPC: G06F12/12
Filed: 1992-06-25
Abstract: PURPOSE:To increase the hit rate of a cache memory by recognizing a block which is read in sequentially, and regarding the block as an object to be replaced and preferentially leaving a periodically accessed block in the cache memory. CONSTITUTION:A replaced block deciding circuit decides a history of past reference. Then the most past accessed cache blocks are recognized by as many as object cache blocks to be replaced which are stored in a register. At the same time. the cache block which has the lowest frequency is regarded as a block to be replaced according to the information of an access array 8. Then once the replaced block is determined, the cache memory is replaced by using a replaced block output bus 5. In the access array 8, information corresponding to blocks read out when the cache memory is accessed is all cleared. Consequently, the block which is large in the frequency of a fetch request can preferentially be stored in the cache memory.

Abstract: PURPOSE:To uniformize cooling capacity by equal wind velocity by connecting a fan case having an axial fan to a duct having an inclined surface toward a ventilation port by a connection part having a blow passage formed thereto and forming an airflow control plate to the blow passage. CONSTITUTION:The ventilation port 8 of a duct device 7 is opened to the upper part of the frame body 4 of an irradiation ventilating unit 2 equipped with a reflecting body 3 having a high voltage discharge lamp 1 enclosed therein.

Title: Reheat steam system for boiler
Inventor: SATO SUSUMU
IPC: F22G5/18
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce damage of a connecting pipe by respectively providing an inlet and an outlet of a primary reheater with connecting pipes and interposing a steam flow control valve in the connecting pipes in a reheat steam system wherein reheat steam is made to flow into two flow reheat steam lines and heated by a first and second reheaters in the respective reheat steam lines before being fed to a turbine again. SOLUTION: When a control valve 10 in a left reheat steam line is opened, steam flow in the left line increases by an amount corresponding to a capacity of the connecting pipe 9, reducing loss of pressure so that steam flow through the left reheat steam line becomes greater than that through a right reheat steam line in a reheat steam flow piping 5. On the other hand, since the overall amount of the reheat steam through a connecting pipe inlet 1 of a steam reheater is constant, steam flow through the right reheat steam line is reduced.  If amounts of heat absorbed by a primary reheater 2 and a secondary reheater 4 are constant, temperature of the reheat steam in the left reheat steam line is lowered by an amount corresponding to the increase of the reheat steam flow and temperature of the reheat steam in the right reheat steam line is raised by an amount corresponding to the reduction of the reheat steam flow. Thus, cooling water through a steam reheater desuperheater control valve 8 is not used, or even if the cooling water is used, the amount of the cooling water can be reduced. Damages of the connecting pipes, therefor, can be reduced.
