Abstract: A light from a laser light source (11) is collected at a position of a slit (125a) in a vertical direction by a first optical system (12a) to form an intermediate image which is long in a horizontal direction corresponding to an arrangement direction of light modulator elements. An undesired light such as side lobes which appear on the both sides of the intermediate image in the vertical direction is blocked by a slit (125a) and the intermediate image is reformed by a second optical system (12b), to direct a liner illumination light onto the spatial light modulator (13). Thus, in a state where moving ribbons are sagged and first order diffracted lights are emitted in a light modulator element, it is possible to prevent a zeroth order light from being emitted from both end portions of ribbons, to thereby enhance contrast of the signal light.

Abstract: In each light modulator element of a special light modulator with diffraction grating structure where moving ribbons and fixed ribbons are alternately arranged, the maximum light-amount (I1) when an output light-amount first becomes maximum from when the moving ribbons start to sag and the maximum light amount-voltage becoming an displacement amount (P1) at the maximum light-amount, are obtained and the minimum of a plurality of maximum light-amounts is set as a target ON light-amount (It). Since a voltage (corresponding to a displacement amount (Pt1)) between the maximum light amount-voltage and the minimum light amount-voltage at a displacement amount (P2) is obtained as a target ON-voltage for the target ON light-amount (It), it is thereby possible to prevent moving distance of the moving ribbons among ON/OFF from largely differing among the light modulator elements and achieve an appropriate image recording.

Abstract: A washing machine having a rinse mode for rinsing laundry placed in a tub of the washing machine. Rinse mode control means controls water supply to the tub and rotation of the tub to carry out a spin dry rinse mode. The spin dry rinse mode includes a first operation during which water is supplied into the tub while the tub is rotated and a second operation during which the supply oft water is stopped and the tub is rotated. The washing machine further includes means for detecting the amount of laundry put into the tub. A rinse time change means controls the time for spin dry rinse mode in accordance with the amount of laundry detected. Thus, time can be saved and water conserved while still effectively rinsing the laundry.
