摘要:
An angular rate sensor is provided which measures the angular rate of a moving object such as an automotive vehicle. The angular rate sensor includes an installation base and an oscillator. The oscillator is excited to oscillate in a preselected direction perpendicular to an axis of rotation of the moving object and provides a signal indicative thereof. The installation base is used for installation of the sensor on the moving object and has an improved orientation structure for orienting the oscillator relative to the installation base during installation of the oscillator on the installation base so that the oscillator may oscillate in the preselected direction. The angular rate sensor is disposed within a casing through improved vibration isolators for absorbing unwanted vibrations impinging upon an operation of the sensor.

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 .eta..sub.R0 /.eta..sub.00 of a first diffraction efficiency .eta..sub.00 and a second diffraction efficiency .eta..sub.R0, is calculated. The diffraction efficiency .eta..sub.00 is dependent on two object light beams. The efficiency .eta..sub.R0 is dependent on the object light and the reference light. In a second step, the intensity E.sub.O of the object light and the intensity E.sub.R of the reference light is adjusted in such a way that the ratio .eta..sub.R0 /.eta..sub.00 is set to at least 10 and the efficiency .eta..sub.00 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.

A lubrication pressure controller comprises a lubrication pressure regulating valve 41, which is provided in a lubrication oil passage 36 directing hydraulic oil to lubricated parts, and a cooler pressure regulating valve 42, which is provided in a discharge oil passage 51b of the lubrication pressure regulating valve 41. The lubrication pressure regulating valve 41 adjusts the pressure in the lubrication oil passage 36, and the cooler pressure regulating valve 42 adjusts the pressure supplied to an oil cooler 55. The hydraulic oil discharged from the cooler pressure regulating valve 42 is returned through a recirculation line 52 to a suction oil passage 31 of a pump. In this construction, an adequate supply of lubrication oil is maintained even if one of the valves experiences locking of a valve spool on an open side. Moreover, by providing signal pressure generating means 60, which applies a signal pressure to these two valves in correspondence with a driving condition, the lubrication pressure controller can be set to acquire a desired balance in the lubrication, cooling and recirculation for the hydraulic oil in response to a driving condition.
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.
