Title: Flow cytometer
Inventor: KUBOTA FUMIO
IPC: G01N15/02
Filed: 1994-12-26
Abstract: PURPOSE: To display a desired image easily by picking up a particle image when the coordinates representative of a detected particle are present in a designated coordinate region. CONSTITUTION: A data processor 100 obtains various feature parameters and an image pickup control circuit 200 judges the kind of each cell in real time using these parameters and controls so that the image only of a previously designated kind of cell can be selectively picked up. When a designated kind of cell is judged to be so, an emission trigger signal for picking up the image of that cell is outputted to a pulse light source 2. A pulse light is then introduced through an optical fiber to a sheath flow cell and a sample flow is irradiated therewith. A pulse light transmitted through the sample flow is focused through a projection lens onto the light receiving face of a video camera and the optical transmission image of the cell is produced. A video signal VS is outputted from the camera 15 to a data processor 300 and a digital image is stored therein.

Title: Plate-shape measuring apparatus
Inventor: TAKAHASHI NOBUYUKI
IPC: G01B11/24
Filed: 1991-12-06
Abstract: PURPOSE:To obtain a plate-shape measuring apparatus, which can measure the strain of a plate material highly accurately, with the simple constitution of the apparatus. CONSTITUTION:The elongations of a plate at a plurality of predetermined measuring points in the direction of the width of a plate material under movement are compared. Thus, the strain of the plate material is measured. In this plate-shape measuring apparatus, a fluorescent lamp 1, which is arranged in the direction of the width of the plate material, is used as a light source. The image of the fluorescent lamp 1, which is reflected on the surface of the plate material, is photographed with a CCD camera 3. In this measuring apparatus, the slant angle of the plate material is obtained out of a table, wherein the relationship between the image position and the slant angle is stored beforehand, based on the position of the image of the fluorescent lamp obtained at every specified sampling period. The length of the slant side is obtained based on the slant angle. The profile length of the plate material is obtained by the integration of the lengths of the slant sides. The profile lengths are measured for, e.g. five points in the width direction of the plate material. The strain of the plate is operated based on the measured result.

Title: Voltage-current conversion circuit
Inventor: DEGUCHI KOJI
IPC: H03F3/45
Filed: 1993-12-22
Abstract: PURPOSE:To reduce the variance factors by substituting the source resistance between sources of differential MOS transistors TRs with a MOS TR and continuously setting a mutual conductance gm by its gate voltage. CONSTITUTION:The source (or the drain) and the drain (or the source) of a third MOS FET N0 are connected between sources of first and second MOS FETs N1 and N2. Control circuits 12 and 11 for voltages of gate and back gate terminals of this third MOS FET N0 are provided to determine the mutual conductance gm of a voltage-current conversion circuit by only gain coefficients betaof MOS FETs. Then, variance factors are reduced in comparison with a circuit consisting of differential MOS FETs and resistors. Since the mutual conductance gm is determined by the ratio of gain coefficients beta of differential MOS FETs to the gain coefficient beta of the MOS FET N0 connected between their sources, the circuit is affected by only variance factors due to the shapes of coefficients beta.

IPC: H01L23/528
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent the generation of a crack in each line constituting the power supply lines of a semiconductor device without forming a slit in the lines even while the line width of the power supply lines is made wide and the resistance of the power supply lines is lessened. SOLUTION: A first power supply line is constituted by connecting a conductor 3 and a conductor 5, which consists of a layer different from the layer forming this conductor 3, with each other using via contacts 100. Moreover, a second power supply line also is similarly constituted by connecting a conductor 7 and a conductor 9, which consists of a layer different from the layer forming the conductor 7, with each other using via contacts 200. Each line width of the conductors 3 and 5 is formed in half of the line width of conventional power supply lines, but the line width of the first power supply line has a line width = the line width of the conductor 3 + the line width of the conductor 5 in a result manner because the conductors 3 and 5 are electrically connected with each other. In respect to this, the second power supply line is also similar. Accordingly, the line width of each line is made narrow to prevent the generation of a crack in each line without providing a slit in each line, while at the same time, it is possible that the line width of the power supply lines is made wider than that of the conventional power supply lines and the resistance of the power supply lines is lessened.

Abstract: PROBLEM TO BE SOLVED: To strengthen rigid force while restraining a plate thickness and a height of a lower shell by setting an inside raidus of a folding-back part of a connecting part with a case shell equal to or smaller than the plate thickness, and forming a curved surface having different curvatures having the center on the axis of the case shell. SOLUTION: A lower shell 3 has a folding-back part 3b of a connecting part 3a with a case shell 2, and also has a curved surface 3c of a bottom part of the lower shell 3. The curved surface 3c of the bottom part is formed in different curvatures δ1 and δ2 having the center on the Y-Y axis. The curved surface 3c of this bottom part is formed by setting the curvature δ2 of a central part smaller than the curvature δ1 of an outside part to strengthen rigid force of the lower shell 3. Therefore, a rotary compressor of a low noise can be obtained by strengthening rigidity of the lower shell 3 while restraining a plate thickness (t) and a height (h) of the lower shell 3.

Abstract: PURPOSE:To prevent any drop of thrust of a piston by pivotally supporting a slave arm oscillated toward a piston and a drive arm oscillated in a perpendicular direction between a mover connected to a driven member and the piston to movably engage the oscillation end of the drive arm with an oscillation guide groove. CONSTITUTION:A piston 6 and its connection portion 15 are moved to the right to move a mover 18 at the same speed as that of the connection portion 15 while a roller 29 on the drive arm 22 of an oscillator 20 is engaged with the linear portion 34 of an oscillation guide groove 33. When the roller 29 is engaged with the downinclined portion 35 of the oscillation guide groove 33, it is moved downward and the oscillator 20 is oscillated clockwise to oscillate a slave arm 21 to the right, so that the mover 18 gets slower in speed than the connection portion 15 and stops when the piston 6 hits a head cover 3. When the piston 6 is moved to the right, each portion shows movement in an opposite direction, with the mover 18 decelerated and stopped through similar mechanism.

Title: Retreatment of waste
Inventor: HANSU REHIERUTO
IPC: C10G1/00
Filed: 1988-12-22
Abstract: A liquid fraction and a gas fraction produced during the reprocessing of waste material containing CH compounds by pyrolysis, have a mass ratio approximately equal to 1. Since the liquid fraction is more suitable for further processing than the gas fraction, there is an incentive to augment the liquid fraction at the expense of the gas fraction. In order to achieve this object, the pyrolysis gas is cooled until the benzene and the higher-boiling gaseous constituents of the pyrolysis gas pass into the liquid phase, so that a benzene-containing liquid fraction is produced. A gas mixture containing benzene and toluene is stripped out of the benzene-containing liquid fraction, passed together with the gas fraction at a temperature of 300 DEG  to 450 DEG  C. over a zeolitic catalyst and then separated by cooling into both a fraction which is liquid at atmospheric pressure and a residual gas fraction. As a result, the proportion of the liquid fraction is substantially increased and the economics of the process are substantially improved.
