Abstract: PURPOSE:To prevent unnecessary diffracted light from entering a photodetection part by dividing coherent luminous flux into two linear polarized light beams by a polarization beam splitter, and transmitting them through a 1/4-wavelength plate and setting the angle of incidence on a diffraction grating to a specific value. CONSTITUTION:The coherent luminous flux from a laser 1 is made incident on the polarization beam splitter 9 through a collimator lens 2 and split into the two linear polarized light beams. At this time, the direction of linear polarization of the laser light 1 is set to 45 deg. to the splitter 9. Reflected luminous flux and transmitted light from the splitter 9 are made into circular polarized light beams through 1/4-wavelength plates 51 and 52 and they are reflected by reflecting mirrors 101 and 102 and made incident on the diffraction grating 3. The diffraction grating 3 performs diffraction of (m)th order. Then, the two diffracted light beam are put one over the other by the splitter 9 and made into circular polarized light after being passed through a 1/4-wavelength plate 53, and the light is split by a beam splitter 6 into two pieces of luminous flux, which are passed through polarizing plates 71 and 72 respectively and made incident on photodetecting elements 81 and 82 as linear polarized light beams.

Title: Hydraulic screw down device
Inventor: HONJIYOU HISASHI
IPC: B21B31/32
Filed: 1977-09-20
Abstract: PURPOSE:The hydraulic screw down device which can prevent the offset wear, etc., of the packing, by installing the piston, provided with a projection leaving a specified small clearance, in the cylinder, and also by installing the specified buffer against the horizontal load. CONSTITUTION:By positioning the roll chock 3 and cylinder 1 in the longitudinal direction of the roll and in the direction of rolling, the clearance 5 is settled; and this positioning of the cylinder 1 indirectly settles clearances 7, 9, between the cylinder 1 and piston 11. Accordingly, if a displacement occur between the cylinder 1 and piston 11, the diaphragm 14 absorbs the horizontal load through internally straining the diaphragm 14 itself, so that a sudden displacement between the cylinder 1 and piston 11 is restrained. When the relative displacement between the cylinder 1 and piston 11 becomes excessive, the internal strain of the diaphragm 14 increases, and the projection 10 of piston 11 strikes the inner surface of cylinder 1 with a softened impact.

IPC: B65G27/04
Filed: 1987-05-12
Abstract: PURPOSE:To simplify handling and improve the degree of accuracy in discharging operation of the feeder in the caption for use in precision weighing etc., of bulk material by supporting an operating body connected with a spoon to the feeder body by means of elastic bodies so that an electromagnetic coil mounted to the feeder body is interruptedly energized and excites the operating body. CONSTITUTION:A spoon 17 is fitted to shaft 11 of the feeder body. And the spoon 17 is filled with bulk material, and the feeder is switched on. When power is interruptedly supplied to a coil 8 from a power source 13, a plate 11a of an operating body 11 is interruptedly attracted to a coil-supporting plate 9-side by generated electromagnetic force, and is returned to the original position by the elasticity of springs 3a, 3b when power to the coil is disconnected. Thus, the operating body 11 vibrates in the direction of shaft center, and the spoon 17 also vibrates simultaneously. The bulk material is therefore discharged from the spoon 17. The degree of accuracy in discharging operation can be improved without special operator skills by this constitution.

Title: Circuit apparatus for changing control speed of phase control circuit automatically
Inventor: FURANTSU DEIITAARE
IPC: H04N5/05
Filed: 1988-05-12
Abstract: PURPOSE: To generate a small time constant by providing the circuit device which gradually increases the control speed toward the center of a synchronous window within the range of the synchronous window and gradually decreases after the center is reached. CONSTITUTION: A circuit 13 is made to increase a control current from the edge to the center of the window and then decrease the amplitude from the center to the edge. In this case, the amplitude is switched, namely, the control speed is increased or decreased not stepwise, but gradually. Consequently, time windows 14 of two microseconds provided symmetrically about the center of, for example, a time window 10 are so set as to increase the control current by specific stages. Consequently, trouble in a synchronizing pulse period exerts disadvantageous influence on phase control operation and its control speed at neither the pulse edge nor the pulse center and a smaller time constant can be generated.
