Filed: 1981-03-23
Abstract: PURPOSE:To obtain a small-size and high-performance waveguide type filter with simple and small-size constitution, by controlling forms and refractive index modes of crossing waveguides. CONSTITUTION:A metallic impurity such as Ti is diffused on an electro-optic crystal such as a lithium niobate substrate 1 to form a main waveguide 2 and a branch waveguide 3 having a width of 10mum, respectively. A profile of the refractive index and a crossing angle of a crossing part 4 are selected properly to allow the laser beam of He-Ne or the like incident from the wavetuide 2 to go straightly to a branch path 2' or branch to a branch path 3'. Thus, a small- size and high-performance waveguide type filter is obtained.

Title: Planetary frictional transmission device
Inventor: KINOSHITA KEIJIROU
IPC: F16H13/14
Filed: 1980-04-07
Abstract: PURPOSE: To simplify the structure of a transmission device by adopting a mechanism to give previous pressures to rollers for the transmission of torque and also a screw mechanism of mutual engagement between a shaft and rollers for making use of the axial shifting of rollers caused by the rotation of the shaft.  
     CONSTITUTION: A drive shaft 11 of a planetary frictional transmission device is supported by bearings 12 and 13. When this shaft 11 is rotated clockwise to transmit a decelerated rotational power to a driven shaft 23, a sun roller 16 is given a pushing force toward the left by the rotation of the shaft 11, and thereby, a planetary roller 17 and a ring roller 21 successively in contact with are pushed toward the left. Since the roller 17 is in contact with the roller 21 in a tapered face, the contact face of each roller is given a previous pressure by a radial component force. Consequently, as a frictional force is generated, the roller 16 is given a rotational torque in counter direction to that of a shaft 23, and screwed into a male screw 14 at the end of the shaft 11. This construction permits to simplify the structure.
