Title: Reduction of pressure feed load at pipe transportation of cement mixture
Inventor: UCHISAKI IWAO
IPC: B65G53/52
Filed: 1983-08-29
Abstract: PURPOSE:To reduce pressure feed load at pipe transportation of cement mixture for preventing choko of the pipe by applying ultrasonic vibrations from around a passage of the cement mixture for forming a lubricating layer along the inside wall of the passage. CONSTITUTION:There are provided ultrasonic oscillators 1 through respective vibration transducers 3 around an outlet or transportation pipe 2 of a concrete pump or pressure feed means like that. Ultrasonic vibrations of 20 to 50kHz are applied from around the passage 2 of cement mixture 4 to form a lubricating layer along the inside wall of the passge. Thus, with neither causing any change in moisture of concrete nor supplying any lubricating mixture along the inside wall of the pipe but with ultrasonic vibrations applied to the passage of the cement mixture, pressure feed load at pipe transportation of the cement mixture can be reduced to prevent choke of the passage.

IPC: G03G9/08
Filed: 1984-07-28
Abstract: PURPOSE:To improve fixability, offsettability and blocking resistance by making different the concn. of the cyclized rubber in the surface layer part and central part of toner components. CONSTITUTION:The system consisting of a polymerizable monomer into which a dye pigment, cyclized rubber and other additives according to need are incorporated is dispersed into a dispersion medium where a dispersant exists. The cyclized rubber has the property to migrate to a positive electrode by an electrophoresis method and is classified to an anionic polymer electrostatically charged negative. the cationic polymer electrostatically charged negative. The cationic dispersant prevents the coalescence of the particles with each other and stabilizes the particles by binding ionically with the cyclized rubber incorporated into the polymerizable monomer on the particle surface of the polymer. The toner paticles form a kind of pseudo capsule in the surface layer part of which the cyclized rubber exists much. The inside is so polymerized as to have a relatively low mol.wt. and excellent fixing characteristic. The cyclized rubber having good blocking resistance and excellent developability and wear resistance is usable for the surface layer part.

Filed: 1981-09-30
Abstract: PURPOSE:To simplify the structure and realize automatic exchange of a chuck by opening and closing a pair of clicks which grasps a chuck in connection with a relative reciprocating motion of a chuck holder. CONSTITUTION:When a chuck holder 13 grasps a chuck 14, a pair of clicks 26 is in a state of being locked after getting in touch with a stopper 31 by means of a coil spring 42. Howver, when said holder 13 descends and a lock ring 40 comes in contact with an abutting rod 57, energizing force of the spring 42 is defeated and the clicks 26 is released from the state of being locked. Continuous descent of the holder 13 causes a slant face 37 of the clicks 26 to contact a taper face of a chuck guide 46 and expand so as to grasp the chuck 14. Subsequently, when the holder 13 ascends while grasping the chuck 14, a pair of clicks 26 grasps said chuck 14 more strongly through a motion reverse to the above-mentioned one.

Title: Chroma noise elimination circuit
Inventor: KATO SHINICHI
IPC: H04N9/64
Filed: 1986-07-03
Abstract: PURPOSE:To prevent color permeation without being averaged with a signal preceding one-hour by providing a means to selectively bypass a comb line filter to eliminate chroma noise. CONSTITUTION:A one shot multivibrator 20 generates a control pulse whose pulse width is equal to one-hour period corresponding to the outputs of counters 16 and 18 that are outputted in synchronism with scanning line signals corresponding to the upper end Iu and the lower end Id of a picture I. By means of this control pulse, the ON/OFF-state of analog switches 12 and 14 are converted, and the switch 12 is turned OFF while the switch 14 is turned ON. Accordingly, the scanning line signals corresponding to the upper end Iu and the lower end Id of the picture I are made bypassed through the comb line filter 10 by analog switch 14. As a result, the scanning line signals in a part where the color drastically changes are not averaged with the signals in one- houre period, and hence the color is prevented from permeating.

IPC: F16J1/02
Filed: 1979-12-03
Abstract: PURPOSE: To facilitate fitting work and improve volume efficiency by forming a continuous concave section along the circumference on the external surface of a piston, by applying a film with a thickness of 20W100μ to this piston, and  forming thicker section so that it can match with the concave of the film.

Since the outer diameter of the piston 2 is uniform at normal temperatures the piston 2 can be smoothly fit in a cylinder 1. When the temperature of the piston 2 is raised by adiabatic compression and friction during operation, the diameter of the thick section 4a of the film 4 grows larger than that of other section 4b through thermal expansion and side clearance is reduced. As a result, fitting work is facilitated and volume efficiency is improved.
