Inventor: FUJIWARA KUJURO
IPC: G01N21/91
Filed: 1989-12-27
Abstract: PURPOSE:To allow flaw detection with high accuracy without occurring the problem of the destruction of the ozone layer by forming the spraying agent to be sealed into an aerosol can of 'Flon-134a(R)' or the 'Flon-134a(R)' and a compressed gas selected from gaseous nitrogen, CO2 and air. CONSTITUTION:The spraying agent to be used at the time of sealing respectively (a) a solvent removable dye or fluorescent penetrant essentially consisting of a dye, base solvent and diluting solvent, (2) a detergent essentially consisting of a volatile org. solvent and (3) a rapid-drying type developer essentially consisting of white fine powder and a volatile org. solvent into the aerosol can is formed of the 'Flon-134a(R)' or the 'Flon-134a(R)' and the compressed gas selected from the gaseous nitrogen, CO2 and air. Since the 'Flon-134a(R)' does not contain Cl, this gas does not break the ozone layer and since this gas exhibits the similar behaviors of 'Flon-11(R)' and 'Flon-12(R)', a uniform spraying state is obtainable. The gas is noncombustible and has no inhalation toxicity. The aerosol type liquid penetrant testing agent having high safety is, therefore, prepd. by properly selecting various kinds of the org. solvents.

Title: Device operating by compression pressure and spraying thereinto
Inventor: OKUMA TAKESHI
IPC: F02M63/00
Filed: 1987-12-30
Abstract: PURPOSE:To make high pressure gas and liquid sprayable in and around a top dead center by installing a plunger being operated by compression pressure in facing on a combustion chamber. CONSTITUTION:In this device, there are provided with a plunger body 9 and a plunger 5 in facing on a combustion chamber 3. When a piston 1 enters its suction stroke, negative pressure is produced in this combustion chamber 3 and thereby the plunger 5 shifts in an arrow A direction. With this shifting, oil is fed under pressure to the inside of a hydraulic cylinder 16 via a plunger control shaft 4, while optional fuel is fed to the inside of a high pressure generating cylinder 6 via a needle valve 24. When the piston 2 is reached to a compression stroke top dead center, high pressure oil acts on the plunger 5 whereby it suddenly shifts in an arrow B direction. With this shifting, fuel in the high pressure generating cylinder 6 is sprayed to the combustion chamber 3 from a fuel injection groove 10 via a fuel injection hole 8 by way of a high pressure side fuel pressure-feed hole 7 and a needle valve 20.

Filed: 1990-11-29
Abstract: PURPOSE:To correctly detect a vibration sound by providing vibrating elements having flipper loosely fitted in a plurality of weight parts of different resonant frequencies, and amplifying an abnormal vibration sound in the low frequency region. CONSTITUTION:Weight parts 24-26 are fixed to the end parts of vibrators 4-6 by locking nuts. Annular disk-shape flippers 34-36 are loosely fitted to a part of the weight parts 24-26. The vibrators 4-6 are rigidly fixed to a supporting plate 3 in the inverted, normal and inverted postures, respectively.

The resonant frequency and the amplitude interval are adjusted so that the vibrators 4-6 ring resonators 54-56 when they are agreed with the resonant frequency at, a certain level of the vibration. By distinguishing which of the resonators 54-56 amplify and ring, it becomes possible to correctly detect the vibration sound, and the reason for the abnormal vibration can be easily specified.

Abstract: PURPOSE:To obtain a good erasing characteristic by narrowing the width of guide grooves where recording and erasing are executed and to record signals by a pulse width modulation system with a phase shift type optical disk so as to increase the recording capacity. CONSTITUTION:A recording layer 3 consisting of a material which is changed in optical properties in a difference in heat history of heating by irradiation with a laser beam and cooling is provided on a transparent substrate 1. The recessed or projecting guide grooves are previously formed smaller than the diameter of the laser beam on the substrate 1. The reflected light from the recessed parts of the grooves is advanced in phase when the state of high reflectivity is assumed to be the reference of the phases in order to execute recording and erasing in the projecting parts of the guide grooves. A phase difference increases and a large amplitude is obtd. When the phase of the reflected light from the low-reflectivity state delays. The phase difference decreases and the large amplitude is not obtainable when the phase of the reflected light advances. The reflected light from the projecting parts is delayed in phase when the state of the high reflectivity is assumed to be the reference of the phases in order to execute recording and erasing in the recessed parts of the grooves. The phase difference, therefore, increases and the large signal amplitude is obtd. when the low-reflectivity state advances in the phase. The good erasing characteristic is obtd. even if high-frequencies are overwritten on low frequencies.
