摘要:
The invention provides a process for producing a saponified vinyl acetate polymer (a saponified ethylene-vinyl acetate copolymer in particular) which features a minimum of coloration of molding pellets, a well-inhibited emanation of an odor in melt-molding, a high transparency of the product film and a low incidence of fish-eyes in the film, and a process for producing a vinyl acetate polymer (particularly an ethylene-vinyl acetate copolymer) for use as the starting material for said saponified vinyl acetate polymer having said favorable properties. In accordance with the invention, either vinyl acetate alone or vinyl acetate and one or more other monomers are polymerized in the presence of a hydroxylactone compound and a polymerization catalyst. The resulting vinyl acetate polymer (particularly the ethylene-vinyl acetate copolymer) is then saponified.

The present invention relates to a transparent conductive layered structure having a transparent substrate and a transparent conductive layer and transparent coating layer formed in succession on this substrate, used in, for instance, the front panel of CRT, etc., display devices. The main components of said transparent conductive layer are noble metal microparticles with a mean particle diameter of 1 to 100 nm, wherein the microparticles are made from gold and/or platinum and silver and the gold and/or platinum content is within a range exceeding 50 wt % up to 95 wt %, and a binder matrix. Moreover, the main components of the coating liquid used to form a transparent conductive layer in the production of a transparent conductive layered structure are solvent and noble metal-coated silver microparticles with a mean particle diameter of 1 to 100 nm dispersed in this solvent, wherein the surface of the silver microparticles is coated with gold or platinum only or a compound of gold and platinum and the gold and/or platinum content is within a range exceeding 50 wt % up to 95 wt %.
摘要:
A near-field optical head which reproduces, with high S/N, information recorded with extreme density and is compact in structure. On an electrode (2) is formed a recording medium (3) that emits a light by applying an electric field. Brought into proximity to a recording medium (3) is a near-field optical head (101) having a slider (31) formed with an inverted cone formed hole such that an apex thereof is rendered as a microscopic aperture (6). A microscopic electrode (5) is formed on a side surface (32) of the inverted cone formed hole. An electric field (9) is applied only to a microscopic region to cause light emission. It is possible at the aperture (6) to detect a light emitted only by the microscopic region.

A transparent electro-conductive structure comprising a transparent substrate and formed successively thereon a transparent electro-conductive layer and a transparent coat layer, which is used in, e.g., front panels of display devices such as CRTs. The transparent electro-conductive layer is composed chiefly of i) noble-metal-coated fine silver particles having an average particle diameter of from 1 nm to 100 nm, the fine silver particles being surface-coated with gold or platinum alone or a composite of gold and platinum, and ii) a binder matrix. A transparent electro-conductive layer forming coating fluid used in the production of this transparent conductive structure comprises a solvent and noble-metal-coated fine silver particles dispersed in the solvent and having an average particle diameter of from 1 nm to 100 nm, the fine silver particles being surface-coated with gold or platinum alone or a composite of gold and platinum.
摘要:
A process for dicing a preform made of an oxide single crystal into cut pieces each having a given shape, includes the steps of removing molecules of the oxide single crystal through dissociation and evaporation with an optochemical reaction under irradiation of a laser beam upon the preform, thereby forming grooves on the preform, and then cleaving the preform along the groove.

A connection wire is connected to a part of a rear door popped up in a door-opening direction by an urging force. A pulley rotates responsive to a driving motor inside a wire-winding device to wind the connection wire thereon. In this manner, the rear door is automatically closed. The pulley is urged in a connection wire-winding direction by a power spring. A clutch is between the pulley and the driving motor. When the rear door is pressed by an operator's hands in a door-closing direction while the rear door is being closed, the pulley is rotated by the power spring, thus winding the connection wire thereon and preventing the connection wire from becoming loose. At this time, the connection between the pulley and the driving motor is cut off by the clutch. Thus, the pulley is rotated by the power spring freely and rapidly. In this manner, the rear door can be closed manually even while it is being closed automatically. Further, the connection wire can be prevented from becoming loose and from being sandwiched between the body of the vehicle and the periphery of a rear opening thereof.
摘要:
A drive circuit supplies a FB (feedback) signal having a predetermined frequency to drive electrodes to vibrate a vibrator. An angular velocity detecting circuit detects a vibratory movement caused in a direction normal to an oscillating direction of the vibrator based on a sensing signal of angular velocity sensing electrodes, thereby generating an angular velocity signal. A signal input circuit supplies a diagnostic signal having a frequency different from that of the FB signal, which is entered into the vibrator via diagnosing electrodes. A diagnosis circuit generates a breakdown signal based on a signal responsive to the diagnostic signal which is obtained from at least one of the drive electrodes and the angular velocity sensing electrodes.

A semiconductor acceleration sensor comprises a sensor element having a first surface for receiving an acceleration force and second opposite surfaces disposed generally perpendicular to the first surface, a support for supporting and fixing the sensor element, and a detecting device disposed on the second opposite surfaces of the sensor element for detecting a variation of a physical quantity due to an acceleration force applied to the first surface of the sensor element.
摘要:
A screen layout corresponding to a transaction routine is input to a FORM, and an item and a code of design information corresponding to a screen input are generated as a table. A location of the screen input is associated with a record in a design information table, and the design information table is searched for based on the screen input to display a screen output, in a program design process prior to the program manufacturing process, so that pseudo operations of the transaction routine are performed on the screen. The present invention reduces an amount of feedback after a program is manufactured, by displaying a screen in a similar manner as in actual program execution, and verifying the program, in a program design process prior to a program manufacturing process of a transaction routine, and also makes program generation efficient, by inheriting data from the design process to the program manufacturing process.
