Title: Certificate stamp handling device
Inventor: NAKAMURA SHINYA
IPC: B65H35/10
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To perform certificate stamp stock-taking work rapidly and accurately by providing a plurality of protruding needles that can pierce the perforation of a certificate stamp sheet placed and stored in a lower case, and providing a clamper that can clamp and unclamp the blank part of the placed-stored certificate stamp sheet. SOLUTION: When an upper case 10 is opened to a larger angle than a regulated opening angle, each clamper element 31 is put in unclamping action simultaneously, and each protruding needle 40 pierces perforation Sa, Sb of the certificate stamp sheet S so as to store the stamp sheet S in a placing storable area of a lower case 20. When external force applied to the upper case 10 is eliminated, each clamper element 31 is put in clamping action all together by elastic restoring force so as to clamp a blank part of the stamp sheet S. At the time of tearing off a requested certificate stamp S1 from the stamp sheet thus placed and stored, tearing force is converged on the perforation of the stamp sheet S through a plurality of protruding needles 40 so as to prevent tearing of a part outside of the perforation.

Title: Ink jet printer
Inventor: KITAMOTO ATSUSHI
IPC: B41J29/13
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To avoid the danger of clamping fingers of a user by nullifying a reset command when a carriage holding an ink is on the ink replacement position. SOLUTION: Papers on a printer 10 are ejected forcibly by a computer 22, and a carriage, namely an ink cartridge, is moved to the initial position or the home position and the reset operation is carried out. When the ink cartridge is on the cartridge replacement position as described above and an INIT (initial) signal is input from the host computer 22, the INIT signal is neglected or nullified by the computer 22 so as not to carry out the reset operation to be carried out in response to the INIT signal. Thus the ink cartridge is not moved from the replacement position to the home position to avoid an unexpected situation by this arrangement.

Abstract: PURPOSE:To prevent the occurrence of errors in detected values, by setting a counting part for a run length for every scanning line in an image pickup device only in the interested region. CONSTITUTION:A molten metal part 2a and a molten metal injecting part 3a of fused steel 2 are scanned by the pickup device 8. The image signal from the device is imparted to a binary coating circuit 15. The signals for molten metal part 2a and the molten metal injecting part 3a are made to be a 1, and the signals for a background part is made to be a 0. The output signals from the circuit 15 are inputted to a counter 17 through a sampling circuit 16. The counting is started by the control signal from a timer 19. The counting is stopped by the control signal from a timer 20. The timer 19 generates a signal which is continued for a preset time period T1 which is set by a variable resistor 22 in response to the fall of a asynchronizing signal from a horizontal signal generator 21. The timer 20 generates a signal which is continued for a preset time period T2 through a resistor 22 by the same way. The counted value of the counter 17 is latched by a register 25 in response to the signal from a strobe signal generator 24. The liquid level 5 is detected from the run length (counted value). Therefore the errors in the detected value can be prevented.

Title: Organic sludge treatment
Inventor: YOSHIDA TADAYUKI
IPC: C01B32/942
Filed: 1978-11-07
Abstract: PURPOSE: To easily perform metal-containing sludge treatment using metal reduction by carbon while obtaining by-product of carbide by a method wherein organic sludge containing metal is solidified by quick lime and sparked by carbon electrode.  
     CONSTITUTION: When quick-lime is added to metal-containing organic sludge, much heat generates due to the reaction with water in the organic sludge. The heat causes water-containing organic materials to be dehydrated, dried, and solidified. The solidified sludge is piled in the form of column, and hole is drilled in the center to conduct sparking by carbon electrode. The spark produces very high temperature to permit the solid sludge to be melted from the center, producing carbide. As such, metal-containing reduction by carbon facilitates the treatment of metal-containing organic sludge, yielding additional carbide formation.

Filed: 1985-06-26
Abstract: PURPOSE:To give a predetermined performance of a power generating unit without interposing a mechanical accelerating mechanism by laminating a plurality of the power generating units provided with stationary and movable portions respectively, one of opposed surfaces of both portions having actin applied and the other having myosin applied. CONSTITUTION:A myosin plate 5 is formed with a myosin protein molecular layer 8, and a yarn 9 of actin protein moleculedirected toward the myosin plate 5 side is attached to a groove 7 in a actin plate 6. When these plates are combined with each other and put in solution 11 to fix the mysion plate 5, the actin plate 6 carries out extremely smooth fine movement. This basic constitution is stacked in a plurality of stages. Thus, for example, when the lowermost actin plate 6 is fixed, then the operating speed is gradually accumulated as a power generating unit goes upward from the lowermost stage to show the maximum speed at the uppermost stage. Thus, the operating speed can be accelerated to a predetermined one without damaging the ripple-less smooth operating property.
