Title: Recovery unit for ink jet head
Inventor: NAKAHARA JUNJI
IPC: B41J2/165
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To decide whether ink is sucked or not easily and visually from the outside through a part for monitoring the ink flow provided for a suction tube at least a part thereof. SOLUTION: Since a suction tube 44 and a suction pump 34 are formed of a transparent material, a decision can be made easily whether an ink is sucked or not by simply viewing from the outside. More specifically, the state of piston members 42a, 42b can be monitored from the outside and a decision can be made that the ink is not sucked when the piston members 42a, 42b touch each other to define no pump chamber and that the ink is sucked when the piston members 42a, 42b are separated to define a pump chamber. Furthermore, the ink in the suction cap 32, the suction tube 44 and the suction pump 34 is prevented from being left collectively.

Abstract: PURPOSE:To easily clean a sensor part and judge the degree of dirt on the sensor part at a glance by disposing a light emitting element and a light receiving element in the diagonal parts of the intake part of a dust collecting part body, and providing an opening and closing cap on the outer wall of an intake passage. CONSTITUTION:When an electric blower 9 starts to rotate, the dust swept into a dust collecting part body 8 by a floor nozzle 7 is passed through a hose 10 and an intake part 11 and collected in a paper bag 25. At that time, the light emitted by a light emitting element 15 mounted on the first cylinder 12 of the intake part 11 is prevented from reaching a light receiving element 16 every pass of the dust, whereby the quantity of dust is detected. According to the quantity of dust at that time, a microcomputer 21 on a printed board 19 in an upper cover 4 changes the power of the electric blower 9. If an inaccurate judgment of size and number of dusts takes place, a cap 14 engagingly locked to the second cylinder 13 of the intake part is opened to conduct the detection, whereby the degree of dirt can be seen, and this part can be wiped with a cloth not only from the first cylinder 12 side but also from the second cylinder 13 side.

Filed: 1987-02-27
Abstract: PURPOSE:To improve the performance of an execution object by generating a multiplication instruction code for specific integer division of a FORTRAN program and the loop circuit calculation of a DO loop with a specific increment value. CONSTITUTION:When the FORTRAN program includes the integer division 1 of 3, 5, 6, and 7 and DO loops with increment values of 3, 5, 6, and 7, a constant N based on expressions I is determined for divisors 3, 5, 6 and 7 and a normal value as a divided (a) is multiplied by them to obtain expressions II, thereby substituting a division instruction with a multiplication instruction. for the divisors 5 and 7, a special value is determined as the dividend to preclude an overflow in the middle of arithmetic processing. For the divisors 7, corrections are and by expressions III when the absolute value (b) of the dividend (a) is larger to obtain a quotient by the multiplication instruction. Consequently, a FORTRAN compiler generates a multiplication instruction code object by a multiplication instruction code generation system.

Title: Semiconductor device
Inventor: OZAWA MASAHIDE
IPC: H01L21/822
Filed: 1979-04-09
Abstract: PURPOSE:To improve electrostatic dielectric strength without changing layout of circuit, by broadening width of polycrystalline Si resistance layer at curve or bend. CONSTITUTION:Electrostatic breakdown voltage resistance of protective circuit using polycrystalline Si resistance is determined mostly by voltage resistance of the polycrystalline Si resistance itself, that is, as the polycrystalline Si's thickness, width and resistance value get larger, the voltage resistance becomes higher. On the other hand, these constants are limited by characteristics of MOSIC and the manufacturing procedure, and current is concentrated at curves or bends to excessively heat these section locally, and this is possible to give rise fusing. And therefore, by broadening widths of curve and bend 7 to make them wider than rectilinear section 3, it becomes possible to increase voltage resistance of the polycrystalline Si resistance without expanding area of IC device and therefore to improve electrostatic dielectric strength of the device.

Abstract: PURPOSE: To adjust the length of overlapping part of yarns by adjusting the position of a second stopper for determining the turning position of a filament collecting lever for drawing the end of a yarn unravelled by an untwisting nozzle into an ending hole.  
     CONSTITUTION: A filament collecting lever 105 is turned once to be spaced from a position where it is brought into contact with a first stopper 34, and both ends of a cut yarn are sucked by an untwisting nozzle to be unravelled. When the lever 105 is turned closer to the first stopper 34 again, with the nozzle stopped sucking, to draw out the ends of the yarn in the nozzle, the first stopper 34 is turned to a non-operation position. Therefore, a lever 32 is stopped at a position where it is brought into contact with a second stopper 70 in such a manner as to determine the draw-out of the yarn ends from the nozzle, that is, the length of overlapping part of both yarn ends. The position of an adjusting lever 72, that is, the position of the second stopper 70 is determined by engagement of a pin of the adjusting lever 72 with positioning holes 74aW74v.

Abstract: PURPOSE:To arrange so that a correct spectrum width and its frequency may be detected on real time basis at a site where equipment is installed by making a frequency integer times as much as the resolution frequency of a spectrum analyzer agree with the number of vibrations of a rotary machine. CONSTITUTION:A vibration frequency spectrum is claculated by means of a vibration detection device 1, a band filter 2, and A/D converter 3 and a digital frequency spectrum distribution calculator 4, based on a vibration value input generated by a rotary machine. Next, the maximum value of a spectrum amplitude is compared with the amplitude of each front and back set of side band spectrum of said frequency. If their ratio is at a value higher than prearranged, a sampling interval is increased or decreased according to the comparison results of the both side band spectra. If the frequencies of the both side band spectra are below the prearranged ratio, an arithmetic operator 8 operates a resolution frequency and a digital printer 9 prints out the maximum frequency and amplitude of a frequency spectrum. Under this constitution, it is possible to convert the resolution frequency to a linear spectrum in frequency spectrum analysis.
