Title: Detecting element of oil leakage
Inventor: NAKANISHI SHIROU
IPC: G01N21/53
Filed: 1981-10-27
Abstract: PURPOSE:To be capable of detecting oil leakage of any oils with a simple means, by providing an oil immersible light scattering material to an oil sending pipe line between a luminous part and photodetecting part. CONSTITUTION:An oil leakage detecting element is constituted by providing a luminous part 1 and a photodetecting part 2 face to face and an oil immersible light scattering material 3 consisting of a mat or fine pulverulent body of transparent synthetic fiber or inorganic glass fiber, pulverulent body etc. Scattering of the light is extremely decreased in case of invading the oil in this light scattering material because a refractive index of the oil is about 1.40-1.50 and transmitting quantity of the light is increased. Accordingly, the light from the part 1 is detected by the part 2 and an oil leakage signal is given.

Title: Butt welding method by laser beam
Inventor: SASAKI HIROAKI
IPC: B23K26/00
Filed: 1981-10-29
Abstract: PURPOSE:To perform butt welding by melting a part or the entire surface of the groove faces of materials to be welded to dispose partial penetration or full penetration beads previously near the weld line and to narrow the groove spacing then irradiating and running a laser beam in this groove thereby expanding the permissible groove spacing effectively. CONSTITUTION:A laser beam 3 is irradiated near the groove of either one of materials to be welded, for example, a material 1 to be welded, that is, at about 0.2mm., and is run along the weld line of the materials 1, 2 to melt the material in said part and to form penetration beads 6, thereby narrowing the groove spacing. In the same manner, a beam 4 is irradiated to the other material 2 to form penetration beads 7 thereby narrowing the groove spacing further. A laser beam 5 is irradiated to the narrowed groove spacing and is run along the weld line, whereby the materials are subjected to laser beam welding satisfactorly. If the spacing between the materials 1 and 2 is relatively narrow, it is also possible to narrow the groove spacing by melting the entire groove surface of, for example, the material 1 with the beam 3 and forming full penetration beads 6 on one side.

Abstract: PURPOSE:To enable a good printing quality little variation compact cam mechanism to be formed by a method wherein an edge surface of a cylinder is used as a cam surface, cam rollers are provided at positions of which phases are shifted by 180 deg. to each other, and a constant speed part is provided to its variation curve. CONSTITUTION:A balancer 4 shares guide shafts 3 as a guide, and its straight line motion is guided therewith. Two cam rollers 5, 5' exist on a carrier 2, cam rollers 6, 6' are arranged on the balancer 4, and an edge surface of a cam 7 is so pinched between them as to be free from backlash. The cam 7 is formed in a unitary body with a shaft, is supported with a bearing 8, and is integrated into a cam block 9. The mass of the carrier and the balancer is equalized, and the cam rollers are arranged at positions whose phases are shifted by 180 deg. to the surface of the cam. Further, since cam rollers at two positions of the carrier and the balancer can be practically operated inside one piece of the cam, only one piece of the cam is enough and a support part of the cam roller can be also designed to be small.

IPC: H01Q15/06
Filed: 1979-12-31
Abstract: PURPOSE:To separate or synthesize simply two radio waves different in frequency band without loss and coupling, by providing an electromagnetic lens in front of the antenna aperture part. CONSTITUTION:Electromagnetic lens 21 with focus 3' in front of waveguide primary radiator 23 is provided in front of aperture part 1 of the antenna. Since electromagnetic lens 21 is so set that it may have a sufficient lens function for the high- band radio wave and have hardly the lens function for the low-band radio wave, only high-band radio wave 6 is transmitted to direction 25 through waveguide 23. On the other hand, low-band radio wave 5 is reflected by parabolic reflection mirror 2 and is condensed onto focus 3 and is transmitted to direction 24 through waveguide 22. Though most of high-band radio wave 6 is condensed to focus 3', high band-elimination filter 26 is provided in front of waveguide 22 for the purpose of eliminating high-band radio wave 6 completely.

Filed: 1987-07-13
Abstract: PURPOSE:To release a mold easily, keeping the precision of lens, by means of air injection between a lenticular surface of mold and a surface of lens, where the air enters through a channel formed by moving an insert in a lens mount in the opposite direction to a cavity at the time of releasing. CONSTITUTION:Initially a sliding insert 6 is advanced to push a movable mount 5. Then, an injection molding machine 14 injects molten resin, with which a cavity 1 is filled, and the resin in the cavity 1 is pressurized and formed by means of the lenticular surface 5a of movable mount 5 and the lenticular surface 6a of sliding insert 6. After the resin in the cavity 1 is solidified, fixed mold 2 and movable mold 4 are opened and the lens projects from the mold by the advance of the movable mount 5 and the sliding insert 6. An opening 21 arises by retreating the sliding insert 6 and compressed air is fed to this opening through a pipe 19 and an air chamber 20. Consequently, the air is injected on the surface 5a of the lens, on which the adhesion force is eliminated, and the mold can be easily released without any damage or any precision-degradation of the precisely formed plastic lens.

IPC: G09F9/35
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To provide the light-weight liquid crystal display device having high reflectance without parallax by using liquid crystals driven by two frequencies, changing the frequency, utilizing the fact that the dielectric constant anisotropy of the respective liquid crystals becomes positive or negative in the liquid crystals for respectively changing orientation within an xy plane and in a (z) axis direction by an application voltage, combining them and independently driving the liquid crystals of respective color layers. SOLUTION: On the same substrate, a pair of electrodes 9 are formed parallelly to a (y) axis and a pair of the electrodes 10 are formed parallelly to an (x) axis. In the case of driving only an R liquid crystal 6 first, the voltage of the frequency ν1 for making the dielectric constant anisotropy be negative to the R liquid crystal 6 and making the dielectric constant anisotropy be almost 0 to a G liquid crystal 5 is applied to the electrodes parallel to the (y) axis. In the case of driving only the G liquid crystal 5, the voltage of the frequency V2 for making the dielectric constant anisotropy be almost 0 to the R liquid crystal 6 and making the dielectric constant anisotropy be positive to the G liquid crystal 5 is put on the voltage of driving the R liquid crystal and applied.  In such a manner, by using the liquid crystals driven by the two frequencies, two colors are independently controlled by a pair of the electrodes.

Title: Variable diameter pulley
Inventor: YASUHARA SHINJI
IPC: F16H55/56
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To receive high belt tension with small-sized constitution by providing a rolling bearing interposed between a hub and a base end part of a boss, with an outer ring interference-fitted to the hub, and an inner ring clearance- fitted to the boss. SOLUTION: A second hub 12 of a connecting member 30 provided at a variable diameter pulley 2 is rotatably supported on the base end peripheral surface of a boss 26 fixed to a housing 18, through a rolling bearing 33. In the rolling bearing 33, an inner ring 19 and the boss 26 are fitted with slight clearance and an outer ring 20 is interference-fitted to the second hub 12. The radial clearance of the bearing is larger than normal, but its quantity is set slightly smaller than the deformation quantity of the outer ring 20 receiving generated moment load. The rolling bearing 33 therefore works only at the required time when belt tension is large. Even a small bearing used as the rolling bearing 33 can therefor stand high torque load, and the service life of the bearing can be prolonged.
