摘要:
An optical information recording and/or reproducing apparatus includes an irradiating device including an objective lens, having a curved surface, for irradiating a recording light beam to a magnetooptical recording medium having at least two magnetic layers, which are a recording layer and a reproduction layer, and which are exchanged-coupled to each other, and a magnetic layer for controlling the exchange-coupling force to block the exchange-coupling force between the recording and reproduction layers, a device for applying an external magnetic field modulated according to an information signal to be recorded on the beam irradiated portion of the recording medium to record information on the recording layer and to orient magnetization of the reproduction layer in a direction parallel to the external magnetic field, a splitting device including a polarizing beam splitter for splitting at least light produced by a magnetooptic effect of the recording medium and light produced by diffraction at the curved surface of the objective lens, a detector including a multi-divided photodetector for respectively detecting the split light beams and a device for producing verifying reproduction signals by executing a predetermined computation using detection signals of the detection surfaces of the photodetector.
摘要:
An information processing method and system in which coded or incomplete information is transmitted through a space or through a predetermined transmission line and is received by a user. A program or data needed to demodulate the information is read out from a recording medium, and the received information is demodulated using the read out program or data.

Provided is an instrument capable of performing maxillomandibular registration after an occlusal vertical dimension is accurately registered in the oral cavity of a patient. With the use of these instruments in the oral cavity, maxillomandibular registration can be performed and a prosthesis can be produced in a state where occlusal stability is reproduced by point contact. Further, with the use of an articulator capable of reproducing the shape and movement of the mandible, a prosthesis can be produced regardless of the experience of the operator.

In a work vehicle, a control unit is configured to control a lock-up hydraulic pressure for controlling switching of a lock-up clutch. The control unit is configured to execute a lock-up slippage control for switching the lock-up clutch into a slippage state when the work vehicle starts moving. The control unit is configured to control the lock-up hydraulic pressure based on work instrument load information, pertaining to a load of a work instrument during execution of the lock-up slippage control.

Provided is a device for performing speed change not leading to engine stall in a working vehicle such as a wheel loader while sustaining a required tractive force and reducing fuel consumption. When a speed (“forward”, “second speed”) suitable for a work is selected by a speed change operator, control means makes a modulation clutch engaged in response to the vehicle speed drop and makes a lock-up state where a lock-up clutch is engaged transit to a lock-up and modulation clutch slip state where the lock-up clutch is engaged while the modulation clutch slips. Subsequently, the control means performs a clutch control for causing a transition to both clutch slip state where the lock-up clutch and the modulation clutch slip in response to the vehicle speed drop, thence causing the transition to a torque converter operation state where the modulation clutch is engaged and the lock-up clutch is released.
摘要:
An image formation apparatus comprising a rear plate on which a plurality of wires for connecting electron emission devices are placed; a faceplate arranged in parallel to the rear plate in a frame, on which an image formation material for forming images by radiation of electrons emitted from the electron emission devices is placed; spacers placed between the rear plate and the faceplate and placed on the wires of the rear plate; and getters provided on the wires on which a spacer is not placed but not provided on the wires on which the spacer is placed.

A method of measuring luminance of an image display apparatus, a method of manufacturing the same, and a method and an apparatus for adjusting characteristics of the same, in which accuracy of measurement is improved while reducing time for measuring luminance of a pixel are provided. A plurality of devices that are not adjacent to each other (for example the devices of the same color out of R, G, and B) are selected and illuminated simultaneously, and luminance is measured for each of them. Based on measured luminance, the electron-emitting characteristics of the respective electron-emitting device as are adjusted based on measured luminance.

A pasting method and a pasting apparatus hold a thin plate 1 and a planar member 2 in high flatness respectively on a first holding member 44 and a second holding member 44, a main controller 40a controls a moving mechanism 45 and a parallelism adjusting mechanism 52 on the basis of information provided by position recognizing mechanisms 33 and 34 to align the thin plate 1 and the carrying member 2 with each other in a predetermined positional relation. The main controller 40a controls a moving mechanism 45 so as to move the thin plate 1 and the carrying member 2 relative to each other in a state where a liquid-phase liquid crystal wax heated by a heater 49 is held between the thin plate 1 and the carrying member 2 to spread the liquid-phase liquid crystal wax over the entire surfaces of the thin plate 1 and the carrying member 2. Thus the thin plate 1, such as a semiconductor wafer or a metal foil, can be accurately, surely and efficiently pasted to the carrying member 2, and the thin plate 1 pasted to the carrying member 2 can be readily separated from the carrying member 2.
