Title: Observation of diffraction grating for hologram
Inventor: MASUI AKIO
IPC: G01N1/30
Filed: 1993-09-03
Abstract: PURPOSE:To enable reliable observation of hologram by performing a dyeing processing of the hologram to form a dyed density distribution on a surface to be observed corresponding to a diffraction ratio distribution of a diffraction grating. CONSTITUTION:A crystal 2a of a dyeing processing agent is put into a glass flask container 1 of a dyeing processing device 10 and vapor 2b of the dyeing processing agent is generated sufficiently to perform a dyeing processing of a hologram 4. As an organic material is used for a hologram material, the dyeing processing agent herein used is not specifically limited and, for example, at least one of iodine, osmic acid, bromine, luthenium tetraoxide and the like is selected preferably only if it meets the requirement. A dyed density distribution is formed by the dyeing processing of the hologram 4 in a photopolymer material forming a diffraction grating corresponding a distribution with a different refraction index so that a density distribution can be formed on the surface to be observed relative to the interval of the diffraction gratings. This enables the observation of the density distribution with a microscope high in resolving power thereby achieving highly reliable observation of the hologram.

Abstract: PURPOSE:To enable repeated filling of oxygen having a definite concentration in a vessel using a small-sized light-weight apparatus, by using a means for evacuating an oxygen-enriching membrane supplied with air, pressurizing the obtained oxygen-enriched air and filling the enriched air into a portable container. CONSTITUTION:An oxygen-enriching membrane 1 is held with an oxygen- enriching membrane module 2 and maintained in airtight state. The pressure in the membrane 1 is made to be different from atmospheric pressure by a vacuum pump 5 and the pressure difference is transferred to the surface of the oxygen-enriching membrane 1 with a vacuum tube 4. An oxygen-enriched air can be produced from supplied air by this apparatus. The oxygen-enriched air is transferred through the 1st guide pipe 6 and cooled with a finned heat- exchanger 7. The oxygen-enriched air containing condensed moisture is separated into oxygen-enriched dry air and condensed water in an oxygen-enriched air reservoir 8. The oxygen-enriched air is passed through the 2nd guide pipe 12, compressed with a compressor 13, transferred through a bacteria filter 14 and a metering device 15 and charged through a charging port 17 into a portable container 23 under a definite pressure.

Title: Semiconductor integrated circuit
Inventor: SUGAWARA MICHINORI
IPC: G05F3/24
Filed: 1990-08-22
Abstract: PURPOSE:To reduce the increase of an output current against the increase of a power supply voltage by connecting the drain of a second MOS transistor to the drain of a first MOS transistor in the same channel type a the second one. CONSTITUTION:An n-channel MOS transistor 6 is added while connecting the drain to the drain of an n-channel MOS transistor 4, connecting the source to a bottom potential similar to the n-channel MOS transistor 4 and connecting the gate to a peak potential. In this case, since the increased component of the current of a p-channel MOS transistor 3 to be increased with the increase of the power supply voltage flows through the n-channel MOS transistor 6 to increase the current with the increase of the power supply voltage, the power supply voltage dependency of the current can be reduced. Thus, the increase of the current flowing to the first MOS transistor 4, which increases the current with the increase of the power supply voltage, can be extremely reduced in comparison with the case of having no second MOS transistor 6.

IPC: A46D1/00
Filed: 1990-08-21
Abstract: PURPOSE:To make uniformly distributed alumina in monofilaments of fibers, in comparison with granular alumina and enable the thinning of the monofilaments themselves by including a prescribed length of alumina fibers in a synthetic resin as base material. CONSTITUTION:Monofilaments 10 composing a water-rubbing brush 20 dispose many of satisfactorily hard alumina long fibers 2, 2... uniformly in a synthetic resin base 1 into hybrids, which base 1 composes monofilament bodies. Each monofilament 10 of the brush 20 always has an equal relative repeating frequency of the alumina long fibers 2, 2... as abrasive in any cross section, and all 100% at that. This makes a uniform abrasive face. The alumina long fibers 2, 2... are juxtaposed in the longitudinal direction common to the base 1 itself, and with the increase in alumina percentage content, the fibers 2, 2... do not lose their strong firmness as brush materials, which enables the monofilaments 10 themselves to be thinned and densed.

Inventor: FUKUMOTO SHIGEO
IPC: C22B9/22
Filed: 1990-08-23
Abstract: PURPOSE:To suppress the vibration on the molten metal surface of a melting pool in a mold, therefore to prevent the generation of a double skin and to improve the completion yield of slabs by specifying the ratio of electron beam irradiating energy to the molten pool and to a melting material and appropriately distributing the energy. CONSTITUTION:In the electron beam rod-melting of titanium and titanium alloys, the ratio of irradiating energy to a melting pool 7 in a mold 3 and to a melting material 1 is regulated to (1:3) to (1:8). In the case the above value lies in <1/8, violent vibration with >=5mm amplitude is generated at the lower part of the melting material 1 and at the melting pool 7 on the opposite side. Furthermore, in the case the ratio of the irradiating energy exceeds 1/3, violent vibration is generated over the full circumference of the melting pool 7. As a result, the amt. of the surface of an ingot to be machined remarkably increases, by double skins. Moreover, at the time of irradiating plural places by one electron gun 6 in time allocation, the time allocation shall be executed in such a manner that the irradiating energy lies in the above range.

Next, the tip section of this material 1b is dipped into an electrolyte, and a voltage and a current fed like a pulse whose length is controlled are fed between the material 1b and a ring electrode 2 to form the material 1b having a desired radius of curvature. In this case, a voltage of a pulse must be such a voltage that it becomes uniform in all the crystal planes of the material 1b for electron cathode, so that the voltage and the length of the pulse are determined by experiments. Thereby, it is possible to make the radius of curvature of the material 1b less than several mum.
