Title: Polishing device for pipe internal surface
Inventor: AIZAWA GORO
IPC: B24B27/00
Filed: 1987-03-11
Abstract: PURPOSE:To polish the inside of a pipe smoothly and efficiently in succession, by letting a moving blade being driven by wind force to be fed out of one direction of the pipe inside have a function as an abrasive plate, and constituting it so as to come down against the wind force coming into contact with an obstacle inside the pipe. CONSTITUTION:A device is pulled in an arrow B direction as a whole and a wind is fed to the inside a pipe 1 from a blower. If so, wind pressure is imposed on an abrasive plate 8 lying on a base 7 of a turbine block 3 whereby it stands erect and simultaneously it receives resistance of the wind, turning into a moving blade, and it rotates at high speed together with a main shaft 2. And, during this rotation, the abrasive plate 8 strongly comes into contact with an inner surface of the pipe 1, removing an oxide or the like being stuck thus polishing takes place. And, when the abrasive plate 8 hits against such an obstacle as a snap tap to be projected inside the pipe 1, it falls down to the side of an opposite incline part of the turbine block a little as being guided by a guide member 9. Therefore, it can escape from the obstacle, thus it can clean and polish a first inner surface in succession.

Title: Direct-vision type light wave interferometer for difference of optical path length
Inventor: TAKASAKI HIROSHI
IPC: G01B9/02
Filed: 1980-04-26
Abstract: PURPOSE:To display the optical path difference in the form of the position or azimuth of a spot, by giving a synchronous rectification in terms of the two orthogonal reference signals to the output of a double-frequency polarization interferometer using the laser beam that oscillates the orthogonal two linear polarized beams having different frequencies or the right-left circular polarized beams and then securing an orthogonal display for the output. CONSTITUTION:The laser beam that oscillates the right and left circular polarized beams having different frequencies is reflected by the Brewster's reflectors BRc and BRs to obtain the outputs Vc and Vs through an optical detector. On the other hand, the laser beam is made to pass through the double-frequency polarization interferometer DFI to detect the output Vt. Then an orthogonal display is given through an oscilloscope or XY recorder to the outputs Vx and Vy obtained by giving a synchronous rectification to Vt concerning Vc and Vs. Thus the optical path difference is displayed in the form of a spot. At the same time, the optical path difference can be shown in the form of a linear azimuth if the orthogonal display of Vx and Vy is carried out with the AC voltage proportional to Vx and Vy respectively.

Abstract: PURPOSE: To provide a method for preparing a highly pure metal salt of a fatty acid with a simple process.  
     CONSTITUTION: The method for preparing the metal salt of a fatty acid is composed of subjecting a fatty acid to saponification reaction with alkali hydroxide and then, reacting the resultant alkali salt of the fatty acid with an acidic metal salt to carry out double decomposition, the alkali hydroxide and the acidic metal salt are alternately added to the reaction system for plural times and the saponification reaction and the double decomposition reaction are alternately performed for plural times at 60-100°C so as to reduce the quantity of the unreacted fatty acid. Since this process is easily simplified, the cost down can be attained and further, as the obtained metal salts of fatty acids are highly pure, they can be used as photo-sensitizers for photo-degradable plastics.

Title: Slit illuminating device
Inventor: SASADA KATSUHIRO
IPC: G01N21/27
Filed: 1991-03-20
Abstract: PURPOSE:To provide a slit type illumination device for a microscopic spectro- photometer, which permits a measuring operator to discern the measuring region, by arranging so that the actual measuring region is put identical to the slit illumination image of a stop perfectly. CONSTITUTION:A light source 12 is installed behind a stop 9 to illuminate it. The beam of light having illuminated the stop 9 is cast onto an object to be measured 5 upon passing through the barrel of a microscope and its objective lens 6, and the beam reflected by this object 5 is passed again through the objective lens 6 and led to an eyepiece 8. The light source 12 to illuminate the stop may be a usual lamp, or otherwise an optical fiber light source the rays wherefrom are cast through an optical fiber. Described in optical terms, the size of the stop image does not depend upon the magnification of the objective lens 6 because the beam passes it twice and image formation is made simultaneously on the surface of specimen with a magnitude of 1:1. In the case the light source 12 consists of optical fiber, it does not involve stray beam projection onto the spectroscope due to leak of light or ill influence of lamp heat upon the spectroscope.

Filed: 1987-03-13
Abstract: PURPOSE:To prevent the no-load oscillation of a magnetron by providing a photosensor for irradiating light to the central part of a turntable and receiving the same on the wall surface of an oven frame body. CONSTITUTION:A light emitting part 8a and light receiving part 8b of a photosensor 8 are provided on both side walls 2c of an oven frame body 2. Light rays emitted from the light emitting part 8a irradiate the central part 7b of a turntable 7 and its reflected light rays are received by the light receiving part 8b. The light receiving part 8b operates an operating switch 10a attached to a control circuit 9 connected to a magnetron 6. When a cooking button is depressed by mistake without a material W to be cooked being placed on the turntable 7, the operating switch 10a is turned off, and the power supply to the magnetron 6 is interrupted. Thus, the no-load oscillation of the magnetron 6 can be prevented.

Title: Direction control device for boring machine
Inventor: NOJIRI YOSHIHIKO
IPC: E21D9/08
Filed: 1989-03-09
Abstract: PURPOSE:To ensure proper and easy directional control by applying the constitution wherein an inner pipe is projected toward a forward end for causing a taper ring to cone in contact with the projection of an outer tube, deflecting the inner pipe in a direction opposite to the projection and a cutter is displaced about the center of a spherical axis toward the projection. CONSTITUTION:When an inner pipe 6 is projected forward, a tape ring 9 so coupled to the inner pipe 6 as to be rotatable and restricted in a shift to an axial direction is interfered with a projection 8, and the inner pipe 6 at the coupling part of the tape ring 9 is thereby deflected left horizontally. The inner pipe 6 is supported at the forward end thereof with a spherical bearing 3 and a spherical shaft 4 and so made as to be rotatable and slidable with the spherical shaft 4. It follows, therefore, that a cutter 7 is projected by the projection length of the inner pipe 6 and the forward end of the inner pipe 6 and the cutter 7 are displaced right horizontally, thereby correcting and controlling a drilling direction. Consequently, construction becomes simple and manufacturing cost is reduced. Furthermore, as an actuator such as a hydraulic cylinder is not required in a boring tool, no connection work of a hydraulic pipe is required in piping work and it becomes possible to carry out connection work extremely easily and quickly.
