Title: Parallel data multiplying circuit with sign processing function
Inventor: OTSUKI YUJIRO
IPC: G06F7/52
Filed: 1987-09-30
Abstract: PURPOSE:To increase the multiplication speed by arbitrarily performing multiplication between absolute value data, multiplication between absolute value data and signed data, and multiplication between signed data. CONSTITUTION:When data A is negative signed data and data B is absolute value data having '1' in the highest-order bit, then An=1, Ami=0, Bn=1 and Bmi=1. At this time, an AND gate AG1 outputs a switching control signal of active '1' to a selector SA1, and an AND gate BG1 outputs a switching control signal of non-active '0' to a data selector SB1. Consequently, the selector SA1 outputs an (n-1)-bit complement to a multiplier M1, and the selector SB1 outputs the output of B1-(n-1) to the multiplier M1 as it is. The AND gate AG2 outputs signal '0' to the multiplier M1 and the gate BG2 outputs signal '1' to the multiplier M1. Consequently, the multiplier M1 outputs the product between two input data. Then, a data selector SC1 outputs the complement of the multiplication result to a terminal group Cout by a negative coding circuit FC1.

Abstract: PURPOSE:To enable complete gas/liquid separation during liquid supply by rotatably providing an inner tank device having openings at its peripheral edge with respect to an outer tank device having a liquid supply port and thereby supplying the liquid to the outside of the tank device by the urging force generated as a result of a centrifugal force. CONSTITUTION:Supply of liquid into a tank unit is effected via a through hole formed at the center of a main shaft 6. During ordinary storage of liquid, an inner tank device 7 is kept out of rotation and during liquid supply only, is rotated by being driven. And by rotating the inner tank device 7 via the main shaft 6, the liquid therein is urged and pressed to its peripheral portion by the action of a centrifugal force, is extruded from openings of the peripheral portion, and thus is filled between guide vanes 4 fixed at the inner side of an outer tank device 2 and kept at rest and also filled in the vicinity of a liquid supply port 3. By opening the liquid supply port 3 with the inner tank device being in rotation in this way, the liquid is supplied to the outside of the tank unit by the urging force generated as a result of the centrifugal force.

Title: Method and instrument for measuring concentration of smoke
Inventor: SAITO KEIZO
IPC: G01N21/59
Filed: 1988-09-30
Abstract: PURPOSE:To continuously and separately measure the concn. of the dry soot component and sof component of smoke in real time by heating sample smoke to the temp. higher than the b. p. of the sof component and lower than the ignition point when the oxidizing catalyst of the dry soot component acts and acting the oxidizing catalyst thereon. CONSTITUTION:The sample smoke 3a is heated to the temp. higher than the temp. T1 (the b. p. of the sof component) and lower than the temp. T2 (the ignition point when the oxidizing catalyst of the dry soot component acts) and the sof component particle 17 therein evaporate from the surface. The particles which are not fully evaporated and remain as the small particles burn by coming into contact with the oxidizing catalyst and form the sof component particle treated smoke 3d. The dry soot component in the sample smoke 3a, however, remains unburned in the treated smoke 3d. The result of the measurement is the concn. of the dry soot component in the treated smoke 3d and the concn. of the dry soot component of the original sample smoke 3a if the treated smoke 3d is measured by a transmitted light attenuation type smoke concn. meter 2; therefore, the concn. X1 of the dry soot component in the sample smoke 3a is determined.

Filed: 1994-10-14
Abstract: PURPOSE: To obtain a semiconductor laser device which is not affected by a temperature change, which can control an optical output with high accuracy and whose mounting process is simple by a method wherein a front optical output is used as a monitoring current. CONSTITUTION: An inclination part 2a having an angle of inclination of 45 deg. with reference to the upper part is formed, and a PD 2 as a photodetector, for monitoring, which is used to control the output of a laser beam is mounted on its slope.

Title: Lock mechanism
Inventor: TACHIBANA MASUO
IPC: E05B65/00
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a lock mechanism which admits quickly unlocking by structuring so that it comprises a dead bolt, a groove for accommodation of detent piece formed in a part of the dead bolt, detent piece to be energized by a spring into the groove, a piston piece to be depressed against the spring force, and an air pressure pipeline in which the piston piece is installed slidably by the air pressure. SOLUTION: To lock, a dead bolt 11 is depressed by hand, when the tip of the dead bolt 11 is engaged by a receptacle metal piece 19 to generate locking, and the head of the bolt 11 will get the same level as the oversurface of the body 10 of the lock. To unlock, a pipe having a specified air pressure is connected with the opening 16a in an air pressure line 16, and a piston piece 18 is advanced, which causes a detent piece 15 to retreat against the action of a coil spring 14 to be set off from the detention part 12a. When the piston piece 18 advances, on the contrary, compressed air is introduced to another air pressure line 17 to lift the detent piece 15, which causes the dead bolt 11 to retreat from the receptacle piece 19. Thus unlocking can be done quickly through utilization of the air pressure.
