Title: Apparatus for measuring worn and reduced thickness of heat-transmitting pipe of fluidized bed boiler
Inventor: TAMURA KOJI
IPC: G01B21/00
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To efficiently measure wear and reduction in thickness of a heat exchanger tube at a low cost by bringing a V-shaped jig having a specific open angle into the heat exchanger tube from downward. SOLUTION: A V-shaped jig 2 having an open angle of 120 deg. is brought into contact with a heat exchanger tube 1 from below the pipe 1 for measuring a distance (d) from a lower end of the pipe 1 which gas been worn and reduced in thickness. Then an amount of worn and reduced thickness of the pipe 1 is calculated from a deviation from d0 which is a distance from a lower end of a normal unworn heat exchanger tube 1. That is, the V-shaped jig 2 is pressed from downward to have it in contact with the heat exchanger tube 1, and the distance (d) from the lowest end of the pipe 1 is measured by a displacement gage 3.  A deviation (d0 -d) is calculated from a value of the measured distance (d) and the distance d0 of the normal pipe 1 which has not been worn and reduced in thickness, and an amount of worn and reduced thickness is calculated from a relation between the pre-calculated deviation and the reduced thickness amount. As the distance d0 from the normal pipe 1 which has not been worn and reduced in thickness, a value geometrically calculated from a regulated outer diameter size of the heat exchanger tube 1 to be measured may be used.

Title: Dielectric heat-vulcanizing method
Inventor: ITOU MASARU
IPC: B29C35/00
Filed: 1982-01-20
Abstract: PURPOSE:To vulcanize rubber with an excellent heat efficiency and molding precison in a short time, by a method wherein a mold for heat-vulcanizing a rubber material is made of a dielectric material, either of a surface part of a mold face and a rubber material comprises a dielectric having a high dielectric loss, and a rubber is vulcanized in a dielectric heating furnace. CONSTITUTION:For example, surface parts 11 and 21 of mold faces surrounding a cavity 3 of a split-cavity mold consisting of a top force 1 and a bottom force 2 consists of a material having a high dielectric loss factor and the other part comprises a material having a low dielectric loss, a rubber material is injected through a gate port 12 formed in the center part of the top force 1 to vulcanize it through dielectric heating of it in a dielectric heating furnace. Additionally, the thicknesses and the dielectric loss factors of the surface parts 11 and 21 are arbitrarily selected depending upon a dielectric loss factor and a vulcanizing temperature of a rubber material. Finally, fluorine plastics, fiber-reinforcing resin, and ceramic are most suitable for a mold.

Title: Ink jet recording head
Inventor: IKEDA MASAMI
IPC: B41J2/05
Filed: 1989-01-13
Abstract: PURPOSE:To always supply ink to an ink liquid passage even if bubbles in a common liquid chamber are increased by providing a bubble removing chamber having a sectional area larger than that of the ink liquid passage and smaller than that of the common liquid chamber between the ink liquid passage and the common liquid chamber. CONSTITUTION:Fine bubbles 2 generated at each ink discharge are moved toward a common liquid chamber 7. Then, they arrives at a bubble removing chamber 10, but since the sectional area of the bubble removing chamber 10 is not increased abruptly as the common liquid chamber 7 with respect to an ink liquid passage 6, bubble moving speed in the bubble removing chamber 10 is not so lowered, and the speed for moving the bubbles is obtained. As a result, the fine bubbles are moved toward the common liquid chamber 7 as remaining bubbles 2A while slightly integrating, and grown to an accumulated bubble 3A. Even if the accumulated bubble 3A is pushed forward at the time of supply of ink, the bubble 3A is prevented from moving toward the ink liquid passage due to the presence of the bubble removing chamber 10, the flowing speed of the ink at the time of supply of the ink generated in a boundary is not increased, and the bubble 3A is not entered forward from the removing chamber 10. Further, since the bubble removing chamber 10 laterally communicates with the common liquid passage 7, ink can be supplied to the ink liquid passage 6 through the removing chamber 10, thereby avoiding a malfunction of stopping the discharge.

Title: Oscillation/wave detection device
Inventor: NIIKURA EIJI
IPC: H03L3/00
Filed: 1980-01-25
Abstract: PURPOSE:To improve the rise characteristic of oscillation with the constantly optimum loop gain, by controlling the gain of a positive feedback loop with the output level of the wave detection device in an oscillation/wave detection device using a narrow band filter. CONSTITUTION:In case the device works as a wave detector, the input terminal 6 is set at 0 with the switch 7 kept off. Thus no positive feedback loop is formed to the narrow band filter 2, variable resistor 9, amplifier 11 and switch 7 to cause no oscillation. As a result, the input signal of the wave detection input terminal is filtered through the filter 2 and then detected by the wave detector 3. In the case of an oscillator, the signal is applied to the terminal 6. Then the switch 7 is turned on. Thus the analog output sent from the terminal 8 of the detector 3 is 0 at first, and the output of the inverse amplifier 10 becomes 1 to reduce the resistance of the resistor 9. And the loop gain formed by the elements 2, 9, 11 and 7 increases to start an oscillation and controls the resistor 9 when the output of the amplifier 10 decreases after a rise. Thus the loop gain is reduced.

Abstract: PURPOSE:To obtain a bonded magnet whose magnetic characteristic is high by a method wherein a permanent-magnet bulk body is collapsed by hydrogen, a thin film of a rare-earth element is applied to the surface of an obtained raw-material particle, a molding operation is then executed in a magnetic field and a heat treatment is executed. CONSTITUTION:A permanent-magnet bulk body obtained by quenching and, after that, hot- working the molten solution of an alloy whose fundamental components are a rare-earth element, iron and boron is collapsed by hydrogen; in addition, it is crushed mechanically and classified. A thin film of a rare-earth element is applied to the surface of a classified pulverized body. The body is molded in a magnetic field; after that, it is heat-treated in an inert atmosphere; then, it is impregnated with a resin. That is to say, when the permanent- magnet bulk body is placed in an atmosphere of hydrogen, it occludes hydrogen and is collapsed. In addition, when it is crushed mechanically, a crystal particle 11 is split into a plurality of particles 11a, 11b. However, the particles are placed in the atmosphere of hydrogen and are not subjected to a bad influence such as oxidation or the like. The thin film of the rare-earth element is applied; split faces and the like are protected; the body is molded to a desired shape in the magnetic field and heat-treated. The crystal particles 11a, 11b are bonded at the split faces; a bad influence on a chemical activity by the split faces is eliminated. Thereby, it is possible to obtain a bonded magnet which can display a high magnetic characteristic.
