Title: Production of diffraction grating
Inventor: MATSUSHITA SHIGEO
IPC: G02B5/18
Filed: 1978-09-14
Abstract: PURPOSE: To enable the diffraction grating having the grooves of nearly desired shapes to be created by cutting and polishing the multilayer films laminated with the specific dielectric films in the film thickness direction then etching the polished surfaces.  
     CONSTITUTION: SiO 2  and B 2 O 3  are simultaneously evaporated toward a glass substrate 4 from vapor sources 5, 6 in a vacuum vessel, whereby SiO 2 -B 2 O 3  glass is formed on the substrate 4. At this time the composition of the glass is so controlled as to become the concentrations shown in the figure, thus the galss films 7 of 1000 or more layers whose concentrations change periodically are formed. Next, the substrate 4 is withdrawn from the vacuum system and is cut and polished in the direction perpendicular to the films 7. Thereafter, the substrate 4 with its polished surface 10 being faced downward is dipped in the hydrofluoric acid of the etching solution, whereby the surface 10 is etched according to the concentrations of the composition B 2 O 3  which is easy to be etched. As a result, the diffraction grating formed with the grooves 11 having the saw tooth form section as illustrated is obtained.

Title: Damper pulley
Inventor: WATANABE SATOMI
IPC: F16F15/12
Filed: 1991-04-18
Abstract: PURPOSE:To effectively restrain torsional vibration and bending vibration using one damper. CONSTITUTION:A mass body 3 is joined to a main body surface of a pulley 1 through a rubber elastic body 2 with a fixed thickness to form a dynamic damper. A lot of short fibers 4 are mixed in the rubber elastic body 2 and the short fibers 4 are oriented in the circumferential direction. The rubber elastic body 2 is increased enough in modulus of shearing elasticity in the torsional direction which is the orientation direction of the short fibers 4 as compared with that in the bending direction which is the radial direction, so that even in the case where the inertial mass of the mass body 3 is large, the natural frequency of the damper meets the high-frequency torsional vibration, whereby the torsional vibration can be reduced effectively by the large inertial mass. Furthermore, the bending vibration can be reduced by the radial shearing elasticity of the mass body and the rubber elastic body.

IPC: G03B1/12
Filed: 1977-09-21
Abstract: PURPOSE: To produce driving torque corresponding to large load torque at the releasing of slip joint for wind transmitting the driving torque of a spring motor by way of a variable angular velocity ratio transmission mechanism.  
     CONSTITUTION: When the torque is transmitted to a wind transmission mechanism via the slip joint constituted by a charge lever 104 and cam 106 by the energizing force of the spring 8 of a spring motor 6 through turning of a charge knob 1 and winding of film and shutter charging are thereby performed, then the transmission of the driving torque is stopped by means of a control lever 22 and the pin 11a of a wind stop control gear 11. When this stopping is released by way of a magnet 33 which is energized after shutter operation, the torque is similarly transmitted via variable speed transmission mechanism, etc. by oval gears 101, 102 and the torque being applied to the lever 104 becomes maximum. Hence, the lever 104 goes over the protrusion part 106a of the cam 106 according to large load torque and the slip joint is released upon completion of winding, thus smooth releasing may be performed
