Title: Image memory control circuit
Inventor: TOKITO YASUO
IPC: G11C8/12
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To perform page development of an image data developed in bit map while accessing an image memory at high rate by exchanging specified bits in significant and insignificant bit groups thereby enlarging the page access mode region to the image memory. SOLUTION: Output bits b0-b9 from a CPU 4 are divided into an insignificant bit group of bits b0-b4 and a significant bit group of bits b5-b9 and the bit b5 in the significant bit group is exchanged with the but b3 in the insignificant bit group. Consequently, even if an output address from the CPU 4 is continuous, a dynamic random access memory DRAM 5 is accessed randomly. A DRAM access control section 2 receives an access start signal and a row address from the CPU 4 and outputs a row/column address switching signal to a selector 3. Consequently, the image data can be developed while accessing an image memory at high rate.

Title: Regeneration of activated carbon having hydrazine adsorbed therein
Inventor: MORIMOTO TAKASHI
IPC: B01J20/20
Filed: 1983-03-07
Abstract: PURPOSE:To efficiently regenerate activated carbon by decomposing adsorbed hydrazine, by supplying a hydrogen peroxide-containing solution to a tower packed with activated carbon of which the capacity is lowered by hydrazine adsorption. CONSTITUTION:In a thermal power plant, waste water is passed through a tower packed with activated carbon to adsorb and remove hydrazine therein. A hydrogen peroxide solution is supplied to the activated carbon packed tower of which the adsorbing capacity is lowered by hydrazine adsorption and hydrazine adsorbed with activated carbon is discharged while decomposed into nitrogen and water to regenerate activated carbon. Even if regeneration and adsorption are repeatedly performed, there is almost no change in the adsorbing capacity of the activated carbon.

Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To attain improvement in throughput per unit time by reducing read/ write operation by discriminating the necessity of write before writing print data into a print data storage device. SOLUTION: From the head of primary storage device 22, 32 bytes are read and it is discriminated whether print data are zero or not. When all the 32 bytes are zero in the case of '1' the discriminating processing of the next 32 bytes is started. When they are not zero, it is discriminated whether all the bits are 1 or not. When all the bits are 1 in the case of '3', print data are written in the print data storage device without being read out of the print data storage device. When all the bits are not 1 in the case of '2', 32 bytes in the area to be updated in the print data storage device are read and compared with the first read contents of primary storage device 22. When the contents are coincident, the discrimination of the next 32 bytes is started but when they are not coincident, both the contents are ORed and the result is written in the primary storage device 22.

Abstract: PURPOSE:To extend functions without being restricted by a delay time, by providing a fundamental device of a digital processor, a buffer for terminating an extended device or an extended internal bus for an interface between the extended devices, and a delay variance absorbing circuit. CONSTITUTION:Extended internal buses 111-113 from a fundamental device 1 are terminated by buffers 5, brought to impedance matching and inputted into an extended device 2. In the extended device 2, signal groups received by the buffers 5 are lumped together and the variance of a delay time due to each buffer 5 is corrected by using a clock in a delay variance absorbing circuit 9, and the variance of the delay time between each internal bus is set to a negligible degree and sent to an extended device 3.

CONSTITUTION:A draw out roller 3, an accumlation wheel 26, and a send out belt 20 are continuously rotated, and a kick out roller 2 is begun to rotate by an interlocking mechanism not shown in this figure when a semicircle 3a of the draw out roller 3 with a large coefficient of friction faces a brake shoe 4, kicking out the lowermost paper A between the brake shoe 4 and the draw out roller 3. At this point, encountered by a resistance of the brake shoe 4, a layer of paper is separated into a sheet of paper, and is drawn out along a circumference 3a. When the end of the paper A passes past the kick out roller 2, the kick out roller 2 is stopped by an interlocking mechanism not shown in the figure and suspends the next kick out. During this time, the draw out roller 3 is rotated to a semicircle with a low coefficient of friction to ensure a draw out one by one, thus enabling reliable draw out with a correct interval.

Title: Diaphragm type pressure-actuated valve
Inventor: OOTAKA SHIYOUICHI
IPC: F16K17/18
Filed: 1984-03-01
Abstract: PURPOSE:To prevent the generation of a beating sound by forming a passage to the open air connected to a large air pressure chamber into one having certain inside diameter and length that display a dynamic damper effect. CONSTITUTION:A positive pressure valve A has a valve chamber 2, which is connected to a first connecting port 1a through an air passage 1c, and a diaphragm 4, which partitions a large air pressure chamber 3 at the back of the valve chamber 2. A valve body 6, which closes a valve port 5 connected to the valve chamber 2, is interlocked with the diaphragm 4. By making an open air passage 14 connected to the large air pressure chamber 3, one having certain inside diameter and length, the vibrating energy of the diaphragm 4 is absorbed by a dynamic damper effect due to the air which is let in and out, suppressing the diaphragm 4 from resonating. Thereby, an effect to silence beating sound can be obtained.
