An image capture device according to the present invention includes: an optical system for producing a subject's image; an imager with multiple photodiodes, which reads an electrical signal representing the intensity of light that has been incident on each photodiode from the photodiode, thereby generating an image signal representing the subject's image; a controller, which acquires sensitivity information by photometry in order to adjust the sensitivity of the imager to light and which selects one of multiple methods for reading the electrical signal from each photodiode according to the sensitivity information acquired; and a driver for driving the imager by the reading method selected. The multiple reading methods include a mixing reading method, by which the electrical signals supplied from the photodiodes are added together and then output.

In a DPP-type tracking error signal (TE signal), an offset caused by the difference between the reflectance of a main-beam irradiated part and the reflectance of side-beam irradiated parts is appropriately compensated without individual normalization of an MPP signal and an SPP signal. An analog signal processing unit 40 produces the MPP, MPI, SPP, and SPI signals on the basis of the amounts of received reflected light of the main beam and side beams detected by a photo-detection unit 130, produces a DPP-type TE signal and a CE signal on the basis of the MPP and/or SPP signal, and outputs the analog signals of the TE, CE, MPI, and SPI signals. A digital signal processing unit 50 computes the TE, CE, MPI, and SPI signals, which are converted into digital signals by an A/D conversion block 52, according to a predetermined arithmetic expression so as to produce a TE signal having an offset, which is derived from a variation in the reflectance of the main-beam irradiated part of the optical disk and/or the reflectance of the side-beam irradiated parts thereof, compensated.

A data recording and reproducing device includes: a light emitting element that generates light and emits the light toward an optical recording medium; a light emission control section that feedback-controls an emitted light quantity from the light emitting element; a light attenuating drive section that includes a light attenuating section, and inserts the light attenuating section into an emission path of the light when reproducing data from the optical recording medium and retracts the light attenuating section from the emission path when recording data onto the optical recording medium; and a shock detecting section that detects a shock of a magnitude causing the light attenuating drive section to switch between the insertion and retraction. When the shock detecting section detects the shock during data recording, the light emission control section lowers a control target value of the emitted light quantity from a value set at the time of shock detection.

Provided is a die cushion controller that controls an ascending/descending speed of a die cushion based on a predetermined pressure pattern 56. The pressure pattern 56 has a low pressure target value PL which is first followed by an increased cushion pressure, a high pressure target value PH corresponding to a requisite cushion pressure for retaining a workpiece, and a complementary target value PC which is followed by the cushion pressure at a substantially linear increase rate for a predetermined period of time T2 until the cushion pressure exceeds the low pressure target value PL and reaches the high pressure target value PH. The cushion pressure overshooting the low pressure target value PL continues to follow the complementary target value PC, so that an overshooting amount occurring at a time point at which the cushion pressure reaches the high pressure target value PH can be reduced. As a result, pressure variation in the cushion pressure can be suppressed.

摘要:
A rotary ring (34) formed such that an outer circumference is eccentric with respect to an inner circumference is provided to an outer circumference of an eccentric drum (333) of an eccentric shaft (33). An adjustment ring (41) formed such that an outer circumference is eccentric with respect to an inner circumference is provided to the outer circumference of the rotary ring (34), and a slide (5) is mounted to the outer circumference of the adjustment ring (41). Since the slide (5) and a slide drive unit (30) are arranged to be superposed substantially at the same height, a distance between the slide drive unit (30) and a lower end of the slide (5) can be reduced and the entire height of a servo press (1) can be reduced. In addition, since the height position of the slide (5) can be finely adjusted by rotating the adjustment ring (41), a press working can be performed with high accuracy.

In a disc drive device (10) described as a specific embodiment of the present invention, AC0 to AC12 of ADIP cluster address are associated with AU6 to AU18 of an address unit. A high-order digit of a sector address that has a value of 0 in the case of a former-half cluster (sectors FC to 0D) and 1 in the case of a latter-half cluster (sectors 0E to 1F) is associated with AU5. An address bit ABLG for identifying recording areas of a disc having plural recording areas for land/groove recording or the like is set at 0. These bits of Au to AU18 and ABLG are associated with 15 bits s0 to s14 from the lower side of a 16-bit shift register for generating a pseudo-random number. Moreover, 1 is associated with the most significant bit s15. Thus, the error correction capability for high-density recording data can be improved.
