IPC: G21C17/003
Filed: 1993-04-28
Abstract: PURPOSE:To prevent the deterioration of a piezoelectric element by providing a protecting member from liquid Na at the side of a transmitting/detecting surface of the piezoelectric element which has the thickness of not larger than a specific ratio of the basic resonance wavelength of the element. CONSTITUTION:A stainless plate (protecting member) 4 is set at the front face of a silver electrode 2a at the side of a transmitting/detecting surface of a piezoelectric body 1. Since a nickel thin film is formed in the stainless plate by vapor deposition, sputtering or the like manner, the wettability of the stainless plate 4 to Na is improved. Corrosion by Na is hence prevented. The thickness of the stainless plate 4 is not larger than about 10% the wavelength determined by the basic resonant frequency of the body 1, for instance, 8.6%. A packing member 3 formed of porous ceramic with approximately 10Mrayl acoustic impedance is provided at the front face of a silver electrode 2b. The member 3 supports the piezoelectric body 1, absorbing the ultrasonic waves radiated from the side of the electrode 2a and transmitting only the ultrasonic waves from the electrode 2b to a transmitting medium. In this manner, when the thickness of the protecting member 4 against Na is set to be approximately not larger than 10% the basic resonance wavelength, a good detecting wave having a short wave train length is obtained.

Title: Method for extrusion molding
Inventor: MIWA MASAKI
IPC: C04B28/02
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To inexpensively manufacture an extrusion molding having deep carving and a smooth fine design by incorporating wheat flour in a kneaded material, incorporating a methyl cellulose and further incorporating a water absorbing polymer. SOLUTION: A kneaded material contains wheat flour, a methyl cellulose and further a water absorbent polymer. In this constitution, as a binder, the flour and the methyl cellulose are used. The flour has a thickening action but does not excessively give adhesive properties to a molding like the methyl cellulose. Accordingly, the molding according to this method does not have such excess adhesive properties as a molding made by adding excess the methyl cellulose has, and a protrusion and recess portion having large carving can be formed. Since the flour is remarkably lower in cost than that of the methyl cellulose, its molding cost becomes low.

Inventor: ITO KIYOSHI
IPC: G01N7/00
Filed: 1992-04-22
Abstract: PURPOSE:To obtain a safe, small-sized, and easily usable odor concentration measuring instrument. CONSTITUTION:A needle valve is inserted into a gas feeding line 25 in a case 20 and, at the same time, a recovery coupler 30 is fitted to an odor port 22a in a freely removable state. At the time of measurement, the coupler 30 is removed and, until the mixing of a mixer 22 is stabilized, a gas to be measured is recovered from the coupler 30 and discharged to the outdoors through a recovering blower 32. Since all required apparatuses are set in the case 20, this measuring instrument can be easily used and, since the gas pressure is adjusted by means of the needle valve, the concentration variation of the gas can be prevented on the basis of the gas pressure. In addition, since the unnecessary gas is recovered by the coupler 30 and discharged to the outdoors, the occurrence of a measurement error or the health of paneler does not become an issue.

Filed: 1978-08-24
Abstract: PURPOSE:To develop always stable images by controlling the quantity of radiation light of originals based on the surface potential detection output of the portions corresponding to a reflecting plate position having a fixed density. CONSTITUTION:A standard white color plate 80 mounted near an original platen glass 54 immediately before exposing the original is radiated with an original-exposure halogen lamp 46 and the scattering and reflecting light thereof is radiated to a drum 47 via mirros 44, 53, 55 and lens 52, etc. With this quantity of radiation light as a standard quantity of light, the sensitivity quantity of the time of actually exposing the original by moving a lamp 46 is changed to the exposure which the operator has arbitrarily set. A surface electrometer 67 measures the surface potential VL of the portion where the scattering reflected light of the drum 47 is radiated and the value adding +50V to this is made the developing bias voltage VM. As a result, the potential of the toner becomes approximately equal to the bias voltage and since the toner does not deposit on the drum, fog of the original background portions may be prevented and developing of stable images accomplished.
