Title: Clutch device
Inventor: SHIGA TAKASHI
IPC: F16D41/02
Filed: 1982-09-21
Abstract: PURPOSE:To prevent the occurrence of an impact betweem moving elements, by engaging a roller in space between outer and inner rollers after accelerating the outer ring up to the same speed of rotation as in the inner ring, while stopping the load side as soon as the rolle is separated from these inner and outer rings. CONSTITUTION:While rotation of the angle beta from a stopping position attendant upon starting an adjustable speed cam 23, an inner ring 14 is accelerated up to the same speed of rotation as in an outer ring 17 by dint of energizing force of an accelerting cam part 13d and a driving spring 37. When rottion of the angle beta takes place, a roller 15 is engaged in space between the inner ring 14 and the outer ring 17. At just before one rotation takes place, the roller 15 separates from the engagement and the load side is decelerated to the extent that the speed of rotation comes to almost nil by dint of energizing force of a decelerating cam part 13e and the driving spring 37 by the time a projecting part 23b hits a tip part 25b of a stop lever 25, while inertia force at the load side is converted into the accelerating energy of the driving spring 37 being ready for the next rotation.

Abstract: PURPOSE:To suppress the unnecessary oscillation due to broadwise oscillating component radially and to increase the efficiency in conversion of liquid into fine particles, by fixing the metal, in which the sound impedance comes to an intermediate between the piezoelectric oscillator and the liquid to the surface of electrode, in an ultrasonic wave oscillator. CONSTITUTION:Silver-made electrodes 9a, 9b are provided on the entire surface for the front and back of the piezoelectric element substrate 8 made of disc shape ceramic. Further, on the front surface of one electrode 9a, disc shape metal plate 10 is fixed with adhesives. This metal plate 10 is made of metals such as aluminum, copper and brass, which is the same as aluminum, and the sound impedance is 8X10<5>(g/cms). The sound impedance 2 of piezoelectric element and liquid such as kerosene is respectively 22X10<5>(g/cms) and 1X10<5>(g/cms). Since the sound impedance of the metal plate 10 is an intermediate value, the matching of the sound impedance is improved, unnecessary oscillation due to the broadwise oscillation component radially can be suppressed and the efficiency of fine particles of liquid can be increased.

Title: Single-plate color image pickup device
Inventor: MIYATAKE SHIGEHIRO
IPC: H04N9/04
Filed: 1983-09-06
Abstract: PURPOSE:To reduce after-images while keeping the horizontal image resolution at a high level and at the same time to improve the color reproduction performance, by specifying an array of color filters. CONSTITUTION:Color filters are arrayed on the basis of eight picture elements in all, i.e., two horizontal picture elements and four vertical picture elements. The filters Ye which cut off the blue beams and filters Cy which cut off the red beams are arrayed repetitively in both the 2nd and 4th horizontal columns. While filters G which transmit the green color beams are arrayed in the 1st and 3rd horizontal columns. That is, filters Cy and G are arrayed repetitively in the 1st column and filters Ye and G are arrayed repetitively in the 3rd column respectively. In this case, it is avoided that the filters of same type are vertically and adjacently to each other. In such an array of filters, the after-images can be reduced with the horizontal image resolution kept at a high level. At the same time, the color reproduction performance is improved. The same effect is obtained if the filter G is replaced with the filter W.

Title: Crack gage
Inventor: NISHIMURA TOSHIHIKO
IPC: G01L1/00
Filed: 1990-06-26
Abstract: PURPOSE:To make it possible to measure a long crack with the small number of gages by providing a plurality of single-axis gages whose widths become narrower as the positions of the gages approach from one side to the other side on a straight line in parallel on the straight line crossing the surface of a sheet. CONSTITUTION:A plurality of single-axis gages 2 are provided in parallel on a straight line 10 crossing the surface of a resin-based sheet 1 on a crack gage 4. The width Wi of the gage becomes narrower as the positions of the gages approach from one side to the other side of the straight line 10. When K of a crack 8 is measured, the gage 4 is stuck to a body to be measured with a bonding agent so that one end of the gage agrees with a tip 9 of the crack 8 and the straight line 10 agrees with a crack progressing direction line X. Then, the strain output value of the gage 2 is measured with a strain measuring device 6 through a terminal 3. The strain output value is inputted into a computer 7. Stress sigmay or reaction force Fy is computed, and the K value is obtained. The closer the gage 2 to the tip of the crack, the narrower the width of the gage 2 with respect to the strain output value for obtaining the K value. Therefore, the distribution of the stress or the reaction force which is rapidly changed in the vicinity of the tip of the crack can be accurately measured.
