Abstract: PURPOSE: To form always even anodic oxidation films on Al material surfaces by disposing pipes of acid resistance, etc. having injection holes of a hole diameter smaller than the openings of hollow-tube form cathodes within said cathodes having said openings fitted with synthetic resin projecting bodies.  
     CONSTITUTION: Protecting bodies 8 made of synthetic resins are fitted to the hollow-tube-form or curved-face-form cathodes 2 having openings 6 disposed in opposition to the anode Al materials 3 in an electrolytic cell 1 and the pipes 5 for injecting electrolyte provided with injection orifices 4 of a hole diameter smaller than that of the openings 6 are disposed in the cathodes 2. At this time, the abovementioned openings 6 and injection orifices 4 are so positioned as to oppose to each other and the pipes 5 are made of acid- and alkali-resistant material such as vinyl chloride. As a result of this, the increase in the hole diamter of the injection holes 4 through contact reaction of the injection holes 4 and electrolyte is obviated and always a fixed velocity of injection is obtainable unlike with conventional methods, and therefore the even anodic oxidation films may be formed on the Al surfaces.

Title: Neutral beam forming method
Inventor: MIZUTANI TATSUMI
IPC: H01L21/302
Filed: 1987-06-22
Abstract: PURPOSE:To generate a neutral beam with sufficiently large flux by generating the microwave plasma of Ne gas and passing the Ne<+> ions accelerated and extracted from this plasma source to the desired energy through the Ne gas to neutralize them by the charge exchange reaction. CONSTITUTION:Ne gas is guided into an ion source 1 through a gas feed pipe 6. Microwaves are fed to a wave guide 2, plasma is generated in the ion source 1, the positive and negative voltage are applied to ion beam extracting electrodes 4, 5 respectively, and the ion beam with the desired energy is extracted. When the Ne<+> ion beam formed with the microwave plasma passes through the gas containing Ne, the charge exchange reaction of Ne<+>+Ne Ne+ Ne<+> occurs, the Ne<+> ions accelerated to several hundreds eV are converted into neutral Ne and straightly proceed while keeping the kinetic energy of the same several hundreds eV. A neutral beam with high flux can be thereby obtained.

Title: Light beam scanner
Inventor: ABE MICHIHARU
IPC: G02B26/10
Filed: 1978-12-11
Abstract: PURPOSE: To enable linear scanning to be done without compensating the bend of scanning locus by placing a spot light source in the position deviated from the loci of the optical axes of the lenses of a rotary disc having a plurality of lenses made by being given distortion aberrations.  
     CONSTITUTION: The point O 1  when the plane to be scanned is viewed from behind a spot light source S is the rotating center of a rotary disc 6 and the optical axis of a lens l 1  moves on the circle 7 along with the rotation of the disc 6. When there is a distortion aberration in the lens l 1 , the imaging magnification varies with the height of the object. Now, if it is supposed that the optical axis of the lens l 1  be on the point R 0  on the line SO 1 , that the disc 6 rotate clockwise by an angle θ and that the optical axis of the lens L 1  move to the point R, forming the image of the spot light source S at the point Q 1  simply entails having the lens l 1  of so-called barrel- form of the characteristics wherein the image magnification decreases with an increase in the height of the object. This constitution yields the light bram scanner which is capable of performing linear scanning without using any bend correcting means for scanning loci.

Abstract: PURPOSE:To make possible always accurate measurement of surface temperatures by shielding  radiation energies from furnace walls and heating source which become disturbances and measuring the emissivity of the measuring object as well. CONSTITUTION:Radiation energies of a black body radiation source 2 through an opening 21 are  condensed and projected by a lens 3 to the surface 11 of a meausuring steel plate 1 with a certain  angle to its normal N.

The radiation energies from the furnace walls and furnace heating source are  shielded by the radiation source 2 and disturbances are completely eliminated. By changing the  temperature of the radiation source 2 and operating by using the outputs of the thermometer corresponding the reto in this way, the emissivity of the heating object may be obtained and its  surface temperature accurately obtained.

Abstract: PURPOSE: To obtain high precision in a simple constitution, by driving a needle type ammeter according to the information of distance to the subject, and transmitting the deflection of the needle to the lens by means of a cap of the type corresponding to the let-off amount of the lens to obtain the focusing point.  
     CONSTITUTION: The distance to the subject is measured by using ultrasonic waves by means of oscillating part 5 and receiving part 6, and an electric signal corresponding to this distance information is issued by a distance measuring device 4. By this electric signal, a needle type ammeter 7 is driven, and a needle 8 moves. When the needle 8 abuts against an inclined part 21a of a cam 21, a let-off lever 11 moves laterally, and the lens-barrel having a lens 9 is moved by a pinion 10 through a rack 12. Since the inclination 21a of the cam is designed to correspond to the shift of the lens 9, when a shutter 2 is closed, always an in-focus picture may be taken. Thus, despite simple constitution, high precision focusing point may be obtained.

Title: Damper
Inventor: FUERUNANDO NABASU
IPC: F16F3/093
Filed: 1993-06-24
Abstract: PURPOSE: To obtain a damper which can be used in a device for stabilizing intervertebra by composing a stop which resists the motion of a piston that exceeds a predetermined quantity of displacement of a piston by a resistance means. CONSTITUTION: When a compressive force acts against ball joints 11 and 31, a piston 3 begins to move from a rest position in contact with a cover 2 to a bottom of a cylinder 1. An elastic member 4 which receives resistance from a strong wall of the cylinder 1 by this motion begins to deform, and the elastic member 4 resists the motion of the piston 3, and the resistance increases progressively. When the volume of a chamber 12 becomes equal to the volume of the elastic body 4 in a state in which the volume of the chamber 12 has already been compressed, resistance that is exerted on the motion of the piston 3 by the elastic member 4 increases in an exponential functional manner, and in a critical point, the piston 3 forms a stop that hinders further motion. In this way, the piston 3 stops.
