To obtain a planar light source which is free from brightness variations or chromaticity variations by using a point light source having a high directivity for emitted light, and to provide a liquid crystal display device capable of obtaining superior display characteristics by using this planar light source device. A planar light source device having an opening in the upper surface comprises a hollow box, a diffusion plate disposed in the opening, a reflecting plate disposed on the bottom of the hollow region of the box, and a plurality of point light sources disposed in a row along at least one side surface of the box. This planar light sources device is characterized by including a refracting element disposed parallel to the row of point light sources and between the point light sources and the hollow region for refracting the light from the point light sources, whereby the light at an incident angle at which the brightness is greatest in the luminous intensity distribution of the light radiated to the irradiation subject surface of the refracting element is refracted to the bottom surface of the box by the refracting element.

A grinding wheel having hollow particles, along with abrasive grains, fixed by a bonding material. The abrasive grains may be diamond grains. The hollow particles may consist essentially of silica. The bonding material may be electrodeposited nickel. The grinding wheel is manufactured by performing an abrasive grain electrodeposition step of immersing a base, with a plating surface being pointed upward, in a plating solution, in which the abrasive grains having a larger specific gravity than the plating solution are dispersed, to deposit the abrasive grains settling in the plating solution on the plating surface, and also deposit a plating metal on the plating surface; and a hollow particle electrodeposition step of immersing the base, with the plating surface being pointed downward, in a plating solution, in which the hollow particles having a smaller specific gravity than the plating solution are dispersed, to deposit the hollow particles floating in the plating solution on the plating surface, and also deposit a plating metal on the plating surface.

摘要:
Trains and points are patrolled by a telegram containing the block occupancy information as a section that only one train is permitted to occupy, the information for giving lock position instructions to a point, and the point position information. This telegram is updated in order to get the right of block occupancy that is not held by other trains, and to give lock position instruction to the point. The train checks the block which this train is allowed to occupy, confirms that the point in this block has been set to the lock position specified by this train. Reading the aforementioned telegram, the point checks the lock position instruction given to itself and controls its lock position. A signaling system characterized by reduced designing and manufacturing costs is provided.

A failure diagnosis apparatus for diagnosing a failure of an evaporative fuel processing system. The system includes a fuel tank, a canister having adsorbent for adsorbing evaporative fuel generated in the fuel tank, an air passage connected to the canister for communicating the canister with the atmosphere, a first passage for connecting the canister and the fuel tank, a second passage for connecting the canister and an intake system of an internal combustion engine, and a purge control valve provided in the second passage. A pressure in the evaporative fuel processing system is detected. An opening of the purge control valve is controlled by changing a duty ratio of a drive signal which drives the purge control valve. First and second filterings of the detected pressure are performed. A second passing frequency band of the second filtering is narrower than a first passing frequency band of the first filtering. A flow rate abnormality of a purge gas flowing in the second passage is determined based on the filtered pressures.

An image processing apparatus determines an embedding method for embedding sub information into a main image to be printed on a recording layer based on the degree of optical shielding of a protection layer or a security layer formed on the surface of the recording layer, on which an image is to be printed, with respect to the surface of the recording layer in a recording medium, and generates a composite image obtained by embedding the sub information into the main image by the determined embedding method as the image to be printed on the recording layer of the recording medium.

After a first copy request is received and copy operation from a copy source area to a copy destination area is activated, information indicating an update section is recorded when a data update of at least one of either the copy source area or the copy destination area is generated. When a second copy request is received, data in the copy source area corresponding to the update section is copied to the copy destination area, in accordance with the recorded information.

A remote-control toy is provided that includes: a controller that transmits a control signal containing an operating instruction based on an operation instruction by a user; a driving device that is driven and controlled based on the control signal; and an extension unit that is capable of receiving the control signal. The extension unit includes: a unit main body and a signal processing device that can be detachably connected to the unit main body. In the unit main body, the received control signal is output to the signal processing device, and processing according to an instruction signal output from the signal processing device is performed. In the signal processing device, the contents of the operating instruction contained in the control signal that is output from the unit main body are discriminated, and an instruction signal based on the operation corresponding to the contents is output to the unit main body.
