Title: Memory circuit
Inventor: AOKI YUTAKA
IPC: G06F12/02
Filed: 1989-03-13
Abstract: PURPOSE:To shorten the time required for a CPU to write and read a memory by generating the address signals ascendingly or descendingly based on the prescribed value set previously and outputting these address signals to a storage part. CONSTITUTION:A memory main body 1, i.e., a memory cell is prepared. A connector 2 which secures the connection to a common bus contains a read/write (R/W) signal line 2-1, a data signal line 2-2, an address signal line 2-3, and a terminal connected to various signal lines forming the common bus. An address generator 3 generates successively the address signals to the main body 1 based on the initial value set previously and synchronously with the processing timing of a CPU. Then the address signals are generated ascendingly or descendingly based on the prescribed value set previously with an instruction inputted from an input part. These address signals are outputted to the main body 1. Thus the access processing time of the CPU is shortened to a memory 10 by an extent equal to the time required conventionally by the CPU to update the addresses.

Filed: 1979-05-18
Abstract: PURPOSE: To obtain excellent operation of the heat exchanger and to prevent the mixing of high- and low-temperature fluids by attaching wet asbestos tape to the contact surface of each component plate of the partition wall.  
     CONSTITUTION: Asbestos tape 10 is arranged on the contact surface of a component plate 5 of a partition wall, and a heating pipe 2 is set in a groove 15.

After the heat pipe 2 is mounted, another asbestos tape which is hydrated, is arranged on it, and another component plate is mounted on this. The operation is repeated to form a partition wall through which the heat pipes 2 are inserted. Reinforcements 11 are arranged to both side ends of the partition wall in order to hold each component plate tightly by using bolts 12. In addition, another reinforcements 13 are arranged, and spot-welded. Thus, the airtightness can be improved, and the mixing of two fluids which perform heat exchange with each other can be prevented.

Abstract: PURPOSE:To enable even a technician, being not skilled in a biological experimental method, to conduct a simple attachement and operation, by a method wherein a microbic supporter, which is obtained from a spongy resin cut piece being immersed and left standing in a bubbling tank at an active sludge treating shop, is attached to an oxygen electrode reacting part. CONSTITUTION:An oxygen electrode consists of a jacket 6, made of an insulating material, an electrolyte 7, a deoxidizing electrode 9, a reference electrode 8, an oxygen permeable film 11, and a fixed nut 10 for the oxygen permeable film. A spongy resin segment 2, containing a microorganism, is firmly adhered to the oxygen permeable film 11 at the reacting part of the oxygen electrode. The microbic supporter is prepared such that spongy resin segments, such as polyurethane form, polyethyleneform in a thickness of 1-3mm., is placed in a net cage and is charged in a aeratoin tank at an active sludge treating shop. The resin segment is immersed and left standing for several days to adhere and proliferate micoorganisms in active sludge to and in the spongy resin cut segments. The use of the micobic supporter permits to perform a simple attachment and operation at the active sludge treating shop even in case the microbic supporter is replaced resulting from the reduction in microorganism activity.

Title: Photomask
Inventor: IMAI KAZUNORI
IPC: G03F1/54
Filed: 1983-04-08
Abstract: PURPOSE:To prevent foreign matter which sticks to a reticle from being transferred onto a wafer by providing a translucent metal vapor-deposited film at a mask pattern formation area part and decreasing light transmittivity to its exposure light beam. CONSTITUTION:A mask pattern 2 is formed on the surface of a glass substrate 1 by, for example, Cr vapor deposition and etching. The translucent vapor- deposited film 3 formed by vapor-depositing, for example, Cr, Al, or Cu in the formation area part A of the mask pattern 2 is much thinner than the mask pattern 2, and this film is formed on the mask pattern 2 or the opposite surface of a reticle glass substrate 1 where the mask pattern 2 is formed. Consequently, the light transmittivity of the mask pattern formation part A is decreased by selecting the film thickness of the vapor-deposited film 3 properly, and consequently an exposure time for obtaining the proper mask pattern is made longer than when this vapor-deposited film 3 is not formed, so foreign matter sticking onto the reticle glass substrate 1 is absorbed completely within the light transmittivity of the vapor-deposited film 3.

Filed: 1992-02-14
Abstract: PURPOSE:To improve measurement accuracy by making measurement reference laser light incident in parallel with a center axis of a magnet having a measurement reference of a space, positioning for magnetic field measurement with the laser as reference and measuring a magnetic field distribution in a magnet. CONSTITUTION:Laser beams 10a, 10b are set to be received by light receiving parts 3a, 3b while only a half of the light is shielded by a probe holder 1, and received light outputs at this time are measured. An x-axis stage 5 is moved on a z-axis stage 4 by an adjusting knob 4a to measure a magnetic field of positions along the laser beams. The tip of the probe 1 fluctuates due to a manufacture error of the stage 4 at this time, but light shielded amounts also vary due to linearity of the laser beams 10a, 10b. Adjustment is made until these amounts are equal to the initially measured values. Thus the tip of the probe holder 1 moves along a z-axis with the laser beam incident in parallel with a center axis of a magnet as reference, permitting the measurement of a magnetic field by a magnetic field measuring element 1a.

Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a tracking error detecting circuit capable of obtaining a correct tracking error signal by canceling an offset to be generated in a photodetection signal by a stray light. SOLUTION: A the time of obtaining the tracking error signal by a WPP (a wobble push-pull) method, push-pull signals are calculated by subtracting the offset value M of the stray light component preliminarily detected with respect to the signal of a total reflected light quantity and using a signal Ig' in which the offset value is canceled. Since the operation of I-R as to the signal L of the light quantity of a total 1st-order diffracted light and the signal R of the light quantity of a total-1st-order diffracted light is performed in a tracking error detecting part 200 and a stary light component is canceled in consequence of this operation, it is not necessary to cancel the offset value positively.
