摘要:
A cathode assembly comprising a cathode, an ion-exchange membrane, and an electroconductive porous member permeable to gas and liquid sandwiched between the cathode and the membrane. The porous member may have, deposited on a part thereof, a catalyst active in hydrogen generation. The porous member preferably is in the form of a plate, sheet, fibers, web, paper, net, or sinter of any of these, and comprises at least a carbonaceous material and has a thickness of from 0.05 to 5 mm and a porosity of from 10 to 95%. Also disclosed is a method of reactivating a cathode assembly, which comprises conducting electrolysis using the cathode assembly until its activity decreases, and then depositing a catalyst active in hydrogen generation on the porous member.

A mobile type service provider terminal registers a service providing area to a presence management server before a service starts. The presence management server creates a status management table of the mobile type service provider terminal. When the presence of the mobile type service provider terminal is detected in an area, the terminal registers information contents, which are delivered to subscribers, to an information delivery server. When the information delivery server stores the registered information contents to an information contents database and completes the creation of an information providing table, it notifies a service control server of the information. The service control server creates a message with reference to the information notified from the information delivery server and delivers it to the subscribers.

Provided is a lighting device having high luminance in-plane uniformity without a dark part occurring at a connecting part between surface light source panels.The lighting device (1) is provided with a plurality of surface light source panel (2), and a plurality of light diffusion passive reflectors (3) disposed at the light-emitting side of the surface light source panel (2). In the light diffusion passive reflector (3), a rectangular-shaped bottom surface is disposed on a light emitting region of the surface light source panel (2), and a light-emitting surface (3a) has substantially the same size as a planar outline of the surface light source panel (2), and a side surface (3c) is formed to incline diagonally outward towards the light-emitting surface (3a) from the bottom surface. The light diffusion passive reflectors (3) which are mutually adjoining are disposed to contact with each other without a gap in between, and are disposed so that the light-emitting surface (3a) is continuously arranged.

This motor control apparatus is provided with: a reduced energy calculation device that calculates a reduced energy that is produced when a drive mode of a hybrid vehicle is shifted from a drive mode driven by a motor to a drive mode driven by an internal combustion engine and if the phase of the motor is changed from the present phase to the arbitrary required phase; a displacement energy calculation device that calculates a displacement energy that is produced when the present phase is changed to the arbitrary required phase; and a phase change permission device that compares the reduced energy and the displacement energy, and permits changing from the present phase to the required phase when it is determined that the reduced energy is greater than the displacement energy.
摘要:
The present invention provides an optical disc apparatus capable of rotating an optical disc with high speed while enabling reduced current consumption. The optical disc apparatus comprises a spindle motor for rotating the optical disc and a thread motor for driving an optical pick-up. When a command is received while the spindle motor is driven, a controller delays operation of the thread motor for a predetermined duration to allow operation of the spindle motor rather than immediately activating the thread motor. After the predetermined duration has elapsed, the controller activates the thread motor and halts the operation of the spindle motor. The predetermined duration may be either a fixed value or a variable value established so as to become smaller as rotation speed of the optical disc increases.

A liquid crystal display includes a liquid crystal panel, an absorption polarizer and a reflection polarizer. The liquid crystal panel includes liquid crystal held between first and second transparent substrates. The absorption polarizer is disposed on an outer side of the first transparent substrate and transmits light vibrating in a first direction and absorbs light vibrating in a direction crossing the first direction. The reflection polarizer is disposed at an outer side of the second transparent substrate and transmits light vibrating in a second direction while reflecting light vibrating in a direction crossing the second direction. The reflection polarizer is held to the liquid crystal panel via an adhesive layer which has a uniform refractive index and contains no light scattering or dispersing beads or particles.

A first display element 1 and a second display element 2 are provided in a stacked configuration. The first display element 1 includes a liquid crystal panel 10 in which a liquid crystal layer 18 is held between first and second transparent substrates 11 and 12, a reflective polarization plate 3 that is provided on the side of the first transparent substrate 11 and a polarization plate 4 that is provided on the side of the second display element 2. In the example shown in FIG. 1, the reflective polarization plate 3 and polarization plate 4 are common to the first display element 1 and the second display element 2. The reflective polarization plate 3 transmits light that oscillates in a specified direction and reflects light that oscillates in a direction intersecting with the specified direction, and is joined directly to the liquid crystal panel 10 via an adhesive layer with a uniform refractive index.
