    摘要： A method for producing a hologram recording an interference fringe formed by an object light and a reference light on a photosensitive dry plate, and the object light either having diffusing and scattering characteristics or being passed through an optical diffusion body, mainly includes the following steps: In a first step, a ratio &eegr;RO/&eegr;OO of a first diffraction efficiency &eegr;OO and a second diffraction efficiency &eegr;RO, is calculated. The diffraction efficiency &eegr;OO is dependent on two object light beams. The efficiency &eegr;RO is dependent on the object light and the reference light. In a second step, the intensity EO of the object light and the intensity ER of the reference light is adjusted in such a way that the ratio &eegr;RO/&eegr;OO is set to at least 10 and the efficiency &eegr;OO does not exceed 5%. A display device using the above hologram is structured by a display unit for generating a signal light; a hologram screen formed by either reflection or transmission hologram, and a projecting unit for projecting the signal light to the hologram screen. According to the present invention, it is possible to easily produce a hologram, for example, a screen hologram, having no cloudiness or cloudy state when an observer observes an image displayed on the screen, and to a display device using the above hologram screen.

    摘要： A coherent beam is converted into a light flux having an expanded width at a predetermined position closer to a photosensitive element. Part of the expanded light flux is irradiated directly on the photosensitive element as a reference beam. The remainder of the expanded light flux is diffused, and its optical direction is changed. Thus, the remainder of the expanded light flux not irradiated directly to the photosensitive element is converted into a scattered beam advancing as an object beam toward the photosensitive element. Interference fringes are formed on the photosensitive element by using the reference beam and the object beam.

    摘要： A hologram of an increased size using a single color laser, capable of executing a full color regeneration in a desired view angle and a method for producing the hologram. A plurality of photo-sensitive members are independently exposed to obtain respective holograms, which are connected by using an adhesive layer 80 constructing a connecting means, in order to obtain an integrated hologram expanded in two-dimensional direction. The holograms are obtained by an interference of a reference light 22 and an object light passed through a light diffusing body 24 in order to cause the light diffusing body 24 to be recorded on the photo-sensitive member. The size of the light diffusing body 24 is such that the spectral characteristic of the diffused light from the hologram can attain a desired efficiency at least over the entire wavelength range of the visible light.

    摘要： A transmission equipped with a continuously variable ratio-change mechanism CVT and a LOW rotational transmission mechanism GT, which are disposed parallel with each other, comprises a forward clutch 65 and a reverse brake 66, which are used to set a power transmission through the continuously variable ratio-change mechanism, a LOW clutch 46, which is used to set a power transmission through the LOW rotational transmission mechanism, and a control unit ECU and a hydraulic control valve HV, which control the engagement of the clutches and the brake. When the transmission is switched from its neutral mode to its in-gear mode, at first, the forward clutch 65 is brought gradually into engagement, and then it is released before the LOW clutch 46 is brought into engagement in a squat control.
