An electrical power tool may include a housing, a rotating tool that is rotatably attached to the housing, a motor that is positioned in the housing and is capable of rotating the rotating tool, a manipulating portion that is attached to the housing, and an indicator device that is disposed in the housing and is capable of indicating a condition of the electrical power tool. The manipulating portion is positioned to substantially cover the indicator device. The manipulating portion is constructed such that light emitted from the indicator device can be transmitted therethrough.

Provided is a lighting apparatus capable of uniformly and efficiently lighting a spatial light modulator. The lighting apparatus includes: a light source for outputting laser light; a multimode optical fiber in which the laser light outputted from the light source propagates through an internal core whose lateral cross section is a substantially polygonal outer diameter shape; and spatial light modulator for producing an image with illumination light from the multimode optical fiber. In the lighting apparatus, the laser light is outputted from the light source and is propagated to the multimode optical fiber in which an outer diameter shape of the lateral cross section of the core is a substantially polygonal shape, whereby the spatial light modulator can be uniformly and efficiently lighted.

A grating alignment device performs alignment of two or more plane gratings so as to eliminate an angular misalignment and a phase misalignment which are caused between respective diffracted light beams generated when incident light is diffracted by the plane gratings. Specifically, alignment is performed by appropriately adjusting an angle A, an angle B, an angle C, a coordinate Z, and a coordinate X of the second plane grating so as to eliminate at least one of the angular misalignment and the phase misalignment which are caused between the respective diffracted light beams generated when incident light is diffracted by the first plane grating and the second plane grating.

There is provided a vehicle system, including an electromobile having a fuel cell power generator mounted therein, and a predetermined mobile unit jointable to the electromobile, such that cogeneration within the mobile unit can be realized even during the travel of the electromobile. Via a joint section 30, a vehicle 10 including a fuel cell 13 as a source of motive power is jointed to a mobile unit 20 capable of travelling and at least including a storage battery 23 and a water tank 25. The water produced in the fuel cell 13 is recovered by a water recovery section 21 via the joint section 30. The heat produced in the fuel cell 13 is recovered by a heat recovery section 22 via the joint section 30. The recovered water is warmed up with the recovered heat, and thereafter stored in the water tank 25. The hot water stored in the water tank 25 is utilized as hot water to be used for controlling the temperature of the mobile unit 20 or supplied as hot water. Any excess electric power generated by the fuel cell 13 is stored in the storage battery 23, and supplied onto electric wiring within the mobile unit 20.

An optical antenna includes an optical element mount (3) for mounting fiber ends (1a and 2a) of optical fibers (1 and 2) at different positions; and an optical transmitting and receiving system (4) for collimating, when laser beams are radiated from the fiber ends (1a and 2a), the laser beams to parallel light rays toward the space, and for focusing, when laser beams arrive from the space, the laser beams onto the fiber ends (1a and 2a) This makes it possible to set two optical transmitting and receiving directions 5 and 6 without installing complicated mechanical elements.

A catalyst 1 is provided in a gas passage 4 for communicating between a gas flow-in unit 12 and a gas flow-out unit 13, and the catalyst 1 is heated by a heater 2, and a temperature sensor 3 for detecting the temperature of the heater 2 is provided inside the heater 2. By feeding power to the heater 2, the wall temperature of the heater 2 is raised to heat the catalyst 1, and then malodorous gas containing odor substances is passed in from the gas flow-in unit 12. The malodorous gas passes through the catalyst 1 in the gas passage 4 to be oxidized to be harmless and odorless, and is discharged from the gas flow-out unit 13.

A refuse compression apparatus for reducing the volume of a thermal elastic refuse includes a telescopic refuse container which is covered by a bag and is housed in a cylindrical housing and suspended on the top of the cylindrical housing. A top cover box is coupled with the telescopic refuse container and the cylindrical housing so that the bag divides the inner space of the cylindrical housing into a free space inside the bag and an airtight space outside the bag. An air pump provided to connect the airtight space and the outside of the cylindrical housing operates to pressurize the airtight space and cause the bag to press the telescopic refuse container upwardly. Thus, the refuse placed in the telescopic refuse container is pressed against the lower surface of the top cover box and is compressed.

The present invention relates to an electronic incinerating apparatus for incinerating organic matter such as garbage having a high rate of water content. This apparatus is composed of a primary combustion chamber (4) into which garbage to be burned is put and a secondary combustion chamber (18) in which decomposition gas of garbage (2) is burned; and the garbage (2) is decomposed or carbonized by microwave in the primary combustion chamber (4), and the decomposition gas is burned by an igniting apparatus in the secondary combustion chamber (18) where no microwave is irradiated. This constitution is characterized in that garbage is dried by microwave to become a good quality fuel, and is thereafter decomposed and burned perfectly, and therefore the exhaust gas is clean and the garbage can be burned perfectly to ashes at high temperatures, so that the treatment is extremely sanitary. The present invention relates to a constitution, control and materials for realizing an electronic incinerating apparatus, and the above-described operation can be carried out by these matters.
摘要:
A controlled atmosphere storage system which is so arranged that a refrigerator and a carbon dioxide generator are connected to each other, and a purifying catalyst, an air preheater, a cooler, a circulating blower and a scrubber are disposed at the downstream side in that order, with the scrubber and the refrigerator being connected, whereby time required for stabilization of combustion may be reduced as compared with conventional systems, and combustion under a low oxygen concentration can be maintained, while flow-out of controlled atmosphere gas outside the refrigerator or entry of atmosphere into the refrigerator can be prevented. Moreover, by forming the carbon dioxide generator in a double wall construction to fill a space with air containing carbon dioxide, heat insulating property is improved for facilitation of combustion under a lower oxygen concentration than in the conventional systems. Furthermore, at starting, since combustion is effected through employment of suction and exhaust paths different from the circulating path, pipe walls are protected against corrosion, and re-ignition under a low oxygen concentration is made possible.
