Abstract:
A CAD/CAM apparatus is adapted such that each set of machining process information representative of machining attributes and the relative machining path and the order of machining are stored in a storage portion associated with each geometric element of each shape of an object, and the machining process information can be modified according to the need and stored again by a machining process edition portion, whereby it is made possible to input information relative to specifications of machining methods in an interactive manner with the display screen. The apparatus is further adapted such that NC data for machining a geometric shape are generated based on the information stored in its storage portion, whereby, differing from prior art apparatuses, it is enabled, even when there are mixed particular specifications of machining conditions for individual part of a geometric shape of the object and a common specification of machining conditions for a unit of geometric shape of the object, to output the NC data for all the shapes in a lump. Further, it is adapted such that any desired portion of the sets of machining process information stored in the storage portion associated with geometric elements can be selectively modified in the machining process edition portion so that new NC data based on the modified machining process information are provided, thereby eliminating the need for re-defining geometric shapes over again in contrast with the prior art apparatuses and enabling the NC data incorporating the modified machining process information to be formed easily and quickly.
Abstract:
A radio that calculates an SINR on a basis of received preamble information received by an antenna and corresponding preamble information stored in advance corresponding to the received preamble information, the radio including: an integration unit that calculates a phase signal for each symbol with respect to the received preamble information; a power value calculation unit that calculates a power value on a basis of the phase signal; a correlation calculation unit that calculates a desired signal power from a correlation value between the phase signal and the corresponding preamble information; and an SINR calculation unit that calculates an SINR value from the power value and the desired signal power.
Abstract:
A valve timing control device comprises a drive rotation member driven by a crankshaft of an internal combustion engine; a driven rotation member fixed to a camshaft that actuates engine valves to open and close, the drive rotation member and driven rotation member being coaxially arranged to make a relative rotation therebetween; a phase varying mechanism that rotates the driven rotation member relative to the drive rotation member within a given angle, the phase varying mechanism being able to cause the driven rotation member to take the most-retarded phase position, the most-advanced phase position and a middle phase position defined between the most-retarded phase position and the most-advanced phase position; and a position keeping mechanism that is able to keep the driven rotation member at least the most-retarded phase position and the middle phase position at the time of starting the engine, and is able to select one of the most-retarded phase position and the middle phase position in accordance with an operation condition of the engine.

Abstract:
The positive-type photosensitive composition according to the present invention contains a novolak resin (A), an alkali-soluble resin (B) selected from the group consisting of resins prepared by addition polymerization of a vinyl compound and condensation polymers such as imide, amide, urethane, urea, ester, and resol resins, an infrared absorbing agent (C), and a sulfonium salt (D). The positive-type photosensitive composition is superior in sensitivity, greater in layer strength, and readily dissociates by infrared ray exposure, and thus is useful as the recording layer for positive-type planographic printing plate precursors.
