摘要:
An optical pickup records information on an optical recording medium and retrieves information from the optical recording medium by radiating a light beam on the optical recording medium. The optical pickup includes a light source which emits the light beam. The optical pickup also includes an object lens which directs the convergent light beam to a recording layer of the optical recording medium. The optical pickup further includes an aberration correction lens assembly located between the light source and the object lens. The aberration correction lens assembly includes at least one movable lens which is movable in an optical axis direction. The aberration correction lens assembly moves the movable lens to convert the light beam to a convergent light beam or a divergent light beam so as to correct spherical aberration. A distance between a principal plane of the aberration correction lens assembly on a light emergent side and a principal plane of the object lens falls within a range determined in accordance with a numerical aperture of the object lens, a focal length of the aberration correction lens assembly on the light emergent side, and a focal length of the object lens.

An igniter includes an igniter body provided with a liquefied gas reservoir, and a rod-like extension, which extends from the igniter body and has a flame port ejecting gas flame therethrough on its leading end. The base portion of the rod-like extension is supported for rotation with respect to the igniter body so that the angle made between the igniter body and the rod-like extension can be changed to change the direction of the flame port in a free state and locked when the igniting action is to be done.

A recorded data storing unit previously stores recorded content data. An index information storing unit stores index information corresponding to portions being grouped depending on attributes of the recorded content from the outside. A playlist creating unit creates a playlist presenting editing targets for the attributes according to specified information specified by a user for the attributes using the specified information and index information appended to the portions of the recorded content depending on the attributes. A playlist storing unit stores the playlist created by the playlist creating unit. A content editing unit edits the editing targets in recorded content in the recorded data storing unit according to the index information in the index information storing unit and the playlist in the playlist storing unit.

The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is not open to a user, the received data is deciphered by a 1394 interface. In contrast, in the personal computer with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key by a 1394 interface, and a result of the decipherment is further deciphered using a session key by an application section.

The present invention aims to provide image processing device and method capable of generating a difference image at high speed without occurring misregistration. To achieve this, in the image processing device and method, plural regions of interest are set respectively to input first and second images, a shift vector indicating a misregistration amount between the first and second images is calculated with respect to each of the regions of interest, a filter process is executed to the shift vector, the filter-processed shift vector is interpolated, the first and second images are registered based on the interpolated shift vector, and a subtraction operation is executed between corresponding pixels on the respective registered images to acquire the difference image.

The present invention relates to a solid formulation for dialysis and a method for producing the same. The formulation is a mixture of: first particles having a coating layer containing magnesium chloride and sodium acetate on surfaces of sodium chloride particles; and second particles having a coating layer containing calcium chloride and sodium acetate on the surfaces of sodium chloride particles, at least one of the coating layers of the first and second particles further including potassium chloride. In the formulation of the present invention, aggregation or consolidation between particles due to moisture absorption thereof can be suppressed. Besides, the content of each component in the formulation becomes uniform, so as to quickly dissolve in water when used. In addition, the formulation of the present invention is an extremely stable solid formulation in which decomposition of glucose hardly occurs even when a formulation containing electrolyte components and acetic acid further contains glucose.

It becomes possible for a user to set a transmission or reception channel arbitrarily and easily. Each of equipment connected to an IEEE 1394 bus may include a register provided within a RAM 113 to thereby set a transmission or reception default channel. If channels used in the transmission and the reception are not set when the transmission is started, then default channel may be used. When equipment is set to a channel setting mode by operating an operation section 116, a control section 112 may display a channel setting picture on a display section 115. In this state, a user may select a set channel by operating an up-key 116a and a down-key 116b of the operation section 116. Thereafter, when a user operates a “YES” key 116c, the control section 112 may write a selected channel in the above-mentioned register, and ends a default channel setting operation. A user can set the transmission or reception channel arbitrarily and easily.

A dynamically reconfigurable processor having a wiring structure which enables flexible mapping of a program to the processor with a small wiring area is provided. The dynamically reconfigurable processor comprises: a first arithmetic circuit group composed of arithmetic circuits of a type Ai (i=1, 2, . . . , N); a second arithmetic circuit group composed of a part of an arithmetic circuit group included in the first arithmetic circuit group and an arithmetic circuit group of a type B which is connected thereto and different from the arithmetic circuit of the type Ai; inter-arithmetic-circuit wires mutually connecting the arithmetic circuits of the type Ai and the arithmetic circuits of the type B; and a switch group which causes the inter-arithmetic-circuit wires in the second arithmetic circuit group to be inter-arithmetic-circuit wires different from other inter-arithmetic-circuit wires and changes the connection order between the arithmetic circuits in the second arithmetic circuit group.
