Inventor: SUGAWARA HAYATO
IPC: F16F9/50
Filed: 1993-07-23
Abstract: PURPOSE:To ensure switching responsiveness in reducing a shock in time of a changeover without lessening the angle of a step motor available in switching the damping force of a shock absorber. CONSTITUTION:The extent of damping force in a shock absorber is switched to more than two steps by the power of a step motor 4. In this case, a motor current is controlled so as, not to make a velocity at the initial stage (within the step angle) in time of transition exceed an angular velocity limit value thetas as detecting an actual position theta. At this time, two processing elements 54 and 56 are selected by two switches SW1 and SW2, and both A- and B-phase currents Ia and Ib are controlled so as to become such an equation as Ia=jXthetasXKXsintheta, Ib=jXthetasXKXsin(theta+90 deg.), and other than this, another processing element 52 is selected, whereby such a current as doing step drive is supplied. In this connection, j is a sign (+ or -1) showing a current direction and K is gain. In place of closed loop control, a transfer velocity may be limited by a constant motor current control pattern.

Title: Silver halide color reversal photosensitive body
Inventor: MURAMATSU YUZO
IPC: G03C5/50
Filed: 1984-08-31
Abstract: PURPOSE:To improve the saturation of colors by having two silver halide (AgX) emulsions having different particle sizes and the same spectral sensitivity and providing AgX emulsion layers in which the silver iodide of the larger particle sizes is incorporated at the higher ratio and the spectral sensitivities are different. CONSTITUTION:A titled material has at least two AgX emulsions having substantially different average particle sizes but having substantially the same spectral sensitivity. The emulsion layer (emulsion layer for controlling the content of the silver iodie) having such relation that the silver iodide content of the larger average particle sizes is higher than the silver iodide content of the smaller average particle sizes among the emulsions and the AgX emulsion layer having the spectral sensitivity different from the spectral sensitivity of said emulsion layer are provided to said material. Many of the iodine ions exhibiting the behavior to control the development are released by the development of the AgX particles and therefore the higher effect of suppressing the development is obtd. by increasing relatively the silver iodide content of the larger AgX particles. The effect of suppressing the development of both emulsion layers having the different spectral sensitivities is improved between the two emulsion layers even if the silver iodide content as a whole is not increased. The preferable color reproducibility is thus obtd.

Title: Power control circuit of electric cleaner
Inventor: MATSUSHIRO TADASHI
IPC: H02P27/02
Filed: 1987-07-22
Abstract: PURPOSE: To perform proper power control of a blower by amplifying the output from a magnetic sensing element installed opposing to a magnet of a valve element using two steps of differential amplifiers, and changing over the signal due to a variable resistor into the amplified signal of the magnetic sensing element and vice versa. CONSTITUTION: The valve element 40 having a magnet 41 fitted to it is installed in an air flow path in a motor-drive blower 53, and a magnetic sensing element 42 is installed opposing to the magnetic 41. When the valve body 40 is shut and the distance between the magnet 41 and sensor elements 42 becomes the shortest, the output of the sensor element 42 maximizes, and the potential difference between the point A and reference point D becomes maximum owing to differential amplification of the first stage amplifier 12. If at this time, a variable resistor 15 is adjusted to make the potential at the point B equal to the point A, the input to the next stage amplifier 21 becomes equal, so that the output X1 becomes equal to the potential at the reference point Y1, and the power of the blower 53 decided by a difference sensing circuit 50 and a phase control circuit 51 becomes maximum.  In case, for example a carpet, etc., is to be cleaned, therefore, a strong power of blower 53 can be available when an at-hand switch 31 is changed over by a switcher 45 to turn on the power nozzle.

Title: Detecting and deciding method of different-size negative film
Inventor: SUZUKI KENJI
IPC: G03B1/00
Filed: 1980-12-23
Abstract: PURPOSE:To decide whether the film frame has a half size or a full size, by detecting whether the notch intervals of a negative film frame is an odd or even times as much as the length of a half-size frame. CONSTITUTION:The passing of a splicer part 3 that joined the nega films together is detected by a photoelectric detector using infrared rays. Then a notch 4 provided to each printable frame is detected, and the shifted extend of a film is counted until the next notch arrives to discriminate a half-size frame or a full-size frame. No notch is given to a defective frame, and accordingly, the film size is not always known by the notch interval. In this respect, if the notch interval is equal to the value an odd times as much as the half-size length, the film is decided as half size.
