A highly reliable rectifying device of a vehicle alternator capable of improving the vibration resistance of a diode. A connection lead 33d of a diode 33 included in a rectifying device includes a linear part 33f extended in parallel from a metallic base 33b, and a bent part 33g bent 90° or more substantially like an arc from the linear part 33f. The bending radius R of the bent part 33g is set to a value larger than a separation distance w in a horizontal direction between the terminal of the linear part 33f and the distal part of the connection lead 33d.

Optical compensation elements include first phase plates and second phase plates, which have retardation in a front-plane direction. When a value Δn/Δnλ is set by normalizing a retardation amount Δn·d relating to light of each of wavelengths by a retardation amount Δnλ·d relating to light of a predetermined wavelength λ, a normalized value Δn/Δnλ in the first phase plate is greater than a normalized value Δn/Δnλ in a liquid crystal layer, and a normalized value Δn/Δnλ in the second phase plate is less than the normalized value Δn/Δnλ in the liquid crystal layer, with respect to light of wavelengths other than the predetermined wavelength.

摘要:
A liquid crystal display includes an insulating substrate, an alignment layer covering a main surface of the insulating substrate, and electrodes interposed therebetween. The alignment layer defines an alignment direction parallel to the main surface, an upstream side as one end's side of the alignment direction, and a downstream side as another end's side of the alignment direction, and tilts liquid crystal molecules toward the downstream side. Each electrode includes an upstream section that includes a first edge facing the upstream side and a downstream section that includes a second edge facing the downstream side and is provided with a recess recessed relative to the second edge. The first recess forms on the downstream section a third edge extending in the alignment direction and a fourth edge connecting the third edge to the second edge and facing the upstream side.
摘要:
In order to set optimum laser power for a disk smoothly and appropriately with a small number of times of test writing, an integrated value Sn is obtained from each kind of laser power Pwn set for the test writing and the modulation factor m(Pwn) of a reflection light intensity obtained through the test writing with the laser power Pwn using an expression “Sn=m(Pwn)×Pwn2”, laser power Pwth is obtained at which the modulation factor m(Pwn) becomes zero when relational characteristics of the integrated value Sn and the laser power Pwn are linearly approximated, and optimum laser power Pw is set based on the laser power Pwth. Here, the optimum laser power Pw is obtained from the target γ value of the disk using an expression “Pw=Pwth×{1+1/(γ+1)}”. The target γ value is obtained from an ADIP of the disk.

Laser power adjustment is performed using a power calibration area (PCA) until the PCA is used up. After the PCA is used up, an additional PCA is reserved at the next recording start position and laser power adjustment is performed using the additional PCA. When an additional PCA is reserved, the additional PCA exists between an information file recorded this time and the last one of information files recorded previously in terms of a physical format. However, information test-written into the additional PCA is not regarded as an information file and PMA information is generated only from the information file recorded this time by excluding the test-written information. As a result, a situation is obtained in which the additional PCA does not logically exist on the disk and there will never occur an inconvenient situation where the additional PCA is erroneously reproduced at the time of reproduction.
摘要:
A signal converting section increases a transfer rate of an input image signal to be supplied to a liquid crystal panel and, at the same time, also inserts a non-image signal for applying a predetermined voltage to liquid-crystal cells in a space of the input image signal and supplies it as a picture-element signal to a source driver. To each picture cell, an input image signal and a non-image signal are sequentially written with positive or negative polarity. For all picture elements, after the input image signal is written, the non-image signal equal in polarity to the input image signal is always written. Furthermore, after the non-image signal is written, an image signal opposite in polarity to the non-image signal is always written. Thus, when an image is displayed on the liquid crystal panel in OCB mode, it is possible to prevent the occurrence of back transition and carry out image display evenly.

A liquid crystal display device includes a liquid crystal display panel (LCD panel), an area light source device which illuminates the LCD panel, a driving unit which drives the LCD panel and the area light source device, and a control unit which controls the driving unit. The LCD panel includes display pixels. The area light source device includes plural kinds of light sources which are successively turned on in one frame period. The control unit includes means for controlling the driving unit in a manner to execute video signal write and reset signal write after the video signal write, in a period in which one of the plural kinds of light sources is turned on in the one frame period. The video signal write and the reset signal write are executed with the same polarity, and a polarity of potential of the display pixels is reversed between frame periods.

A liquid crystal display panel includes an array substrate, a counter-substrate, a liquid crystal layer which is held between the array substrate and the counter-substrate and contains liquid crystal molecules whose alignment state is to be transitioned to a bend alignment for enabling a display operation, a retardation plate which is disposed at least on the counter-substrate, and a polarizer which is disposed on the retardation plate. The array substrate and counter-substrate include a pair of electrodes which are covered with alignment films, respectively, and are opposed to each other to define a rectangular display area, and the polarizer has an absorption axis which is substantially parallel or substantially perpendicular to each of the sides of the display area.
