A screen includes a light diffusion layer in which microcapsules, each having therein a light diffusion liquid that scatters light for displaying a video image, are planarly arranged. The light diffusion layer is fixed to a supporting sheet by a binder material. On a surface of the supporting sheet, a Fresnel lens is formed. A light diffusion plate is made up of the light diffusion layer and the supporting sheet. The screen is made up of the light diffusion plate and a light diffusion plate. Scattering distribution of a scattered wave of light that passes through the light diffusion layer temporally changes.

A projection display device that displays an image by projecting the image onto a transmissive screen from the rear thereof includes: an illumination optical system for guiding a light beam emitted from a laser light source to the transmissive screen; a projection optical system for enlarging an image formed on a region to be illuminated of an image display element, and projecting the enlarged image on the transmissive screen, the projection optical system being configured such that the product of the F-number and the projection magnification of the projection optical system is less than 400; wherein the transmissive screen includes a Fresnel lens and a lenticular lens respectively equipped with a light diffusion layer for diffusing incident light and causing resultant light to exit the light diffusion layer. The light diffusion layer of the lenticular lens has a thickness of less than 300 μm.

The electronic component device includes an electronic component such as a pressure sensor for detecting pressure of fuel injected into an internal combustion engine, an insulating member made of an insulative resin and sealing the electronic component, and a shield member made of a conductive resin and surrounding the insulating member.
摘要:
A fuel injector for an internal combustion engine is provided which has a fuel supply path and a nozzle chamber. The fuel supply path extends a spray hole. The nozzle chamber is defined in the fuel supply path. A nozzle is disposed within the nozzle chamber to establish or block a fluid communication between the fuel supply path and the spray hole. A fuel pressure sensor is installed in the fuel injector so as to be exposed to the fuel in the nozzle chamber. Specifically, the fuel pressure sensor is located closer to the spray hole than a prior art structure in which the fuel pressure sensor is installed in a fuel supply pipe, thus resulting in increased accuracy in measuring a change in pressure of the fuel arising from the spraying of the fuel from the spray hole.
摘要:
A component for an electronic apparatus has an insulating member that has a plurality of through holes in parallel in which the lead wires are inserted and a shield cover in which an insulating member insertion hole where the insulating member is inserted is formed that cut offs an electrical noise. The insulating member is formed in an integrated shape where parts of adjoining cylindrical parts in which the through holes are formed overlapping mutually when seen along an axial direction of the through hole. The insulating member insertion hole becomes a single hole formed identical to an outer shape of the insulating member when seen along the axial direction of the through hole.

A double floor structure capable of being adapted to the conditions of construction and the needs of users at low cost. A double floor structure (K) provided with support legs (1) which are provided on a lower floor and rows of beams which form an upper floor. The support legs (1) are each provided with an upper member (14) which supports a beam from the lower side, an intermediate member (13) which supports the upper member (14) from the lower side, and a lower member (12) which supports the intermediate member (13) from the lower side. The upper member (14), the intermediate member (13), and the lower member (12) consist of metallic, extruded shape material and are disposed in such a manner that the direction of the extrusion is aligned with the top-bottom direction.

A swash plate includes a boss, which is mounted on the drive shaft, and a plate portion, which extends from the boss to be inclined with respect to the drive shaft. A rotary valve includes a suction passage, which sequentially connects cylinder bores in a suction stroke via an associated guide passage. An introduction guide communicates with the shaft bore to introduce the refrigerant gas in the swash plate chamber to the rotary valve. The introduction guide faces the boss and extends in the radial direction from the shaft bore beyond the boss. Therefore, suction efficiency of refrigerant gas from the swash plate chamber to the cylinder bore has improved.

When an unmanned conveyance vehicle travels straight along a main guide tape 12, the rotational speeds of a pair of drive wheels of the unmanned conveyance vehicle are controlled such that the center position O2 of a guide sensor 23 is matched with the center position O1 of the guide tape 12. When the unmanned conveyance vehicle is turned to the right along a branch guide tape 13, a turning operation of the unmanned conveyance vehicle is controlled such that the center position O2 of the guide sensor 23 is matched with an inner side edge 13a of the branch guide tape 13 in the turning direction.
摘要:
A fuel pressure sensor/sensor mount assembly in which a fuel pressure sensor is so mounted as to exposed to a high-pressure fuel path through which fuel is supplied to a fuel injector, a fuel injection apparatus equipped with a built-in fuel pressure sensor, and a pressure sensing apparatus working to measure the pressure of fuel in a fuel injector are provided. The fuel pressure sensor/sensor mount assembly is disposed between the high-pressure fuel path and the fuel injector, thus permitting the size of the fuel injector to be minimized without sacrificing the accuracy in measuring the pressure of the fuel. The fuel injection apparatus and the a pressure sensing apparatus are designed to ensure desired accuracy in measuring the pressure of the fuel.
