Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To enable the formation of hardened layer having difficult-to-develop crack and detachment on the prescibed surface of a casting by incorporating a zirconium-containing compound at a prescribed position on the inner surface of a lime-base mold for casting a titanium or a titanium-base alloy. SOLUTION: Since the zirconium-containing compound exists at a prescribed position on the inner surface of the lime mold, molten Ti abutted on the existing part of the zirconium-containing compound in the mold is gradually reacted to form the hardened layer. The molten Ti abutted on the mold position where does not contain the zirconium but only the lime, is not reacted and the hardened layer is not developed. Therefore, the hardened layer in an arbitrary local part can be formed. Further, kinds and blending ratio of the zirconium- containing compound contained in the lime mold are changed to control chemical reactivity of the casting to the mold. The casting hardened to the arbitrary depth locally and the arbitrary hardness can be cast.

IPC: H04R29/00
Filed: 1986-03-19
Abstract: PURPOSE:To prevent the fluctuation from being generated among testers, by taking a difference between signals outputted to microphones of both units by impressing an audible frequency signal, and identifying a good product and a defective one from a difference voltage. CONSTITUTION:The titled method is set so that an oscillator 9 is operated, and a frequency is fitted to an appropriate one to be set as a reference, and the amplification degree of an auxiliary amplifier 10 is adjusted in the frequency, and the output of a level meter 12 goes to the minimum level. Next, the oscillation frequency of the oscillator 9 is raised gradually little by little from a lower range, changing it to several hundred Hz, or lowered from a higher range. So-called chattering is generated in the range from 20Hz to several hundred Hz. Since the output of the difference signal of the said detector shows a value remarkably increased than an ordinary output, when a testing speaker 6 generates the chattering, it is identified by the level meter 12. In this way, a test can be performed without generating the fluctuation more exactly and rapidly.

Filed: 1978-05-25
Abstract: PURPOSE: To perform correction of illuminance distribution while improving lighting efficiency by forming reflecting films on a part of the outside wall of a fluorescent lamp through vapor deposition according to illuminace distribution.  
     CONSTITUTION: A reflecting film 12 by Al film is evaporated on the outside wall of a fluorescent lamp at its central part except the opening part 11 in the longitudinal direction and a reflecting film 13 by high reflection multilayer films at its peripheral part, respectively. Hence, when the illuminance distribution by the flourescent lamp 10 is observed, direct light together with the light reflected by the reflecting films 12, 13 are radiated to the original plane through opening face 11, whereby the occurrnce of wasteful luminous fluxes is obviated. Even more, the reflecting film 13 by high reflection multilayer films has been evaporated on the peripheral part of the fluorescent lamp 10 where luminance distribution is low and therefore the decrease in the quantity of peripheral light is compensated and the even illuminance distribution is obtained. Since this is not the correction of the quantity of light by shield means, lighting effect may be improved as well.
