A vehicle footrest system allows an occupant seated in a rear seat to brace their feet and that is capable of inhibiting load from concentrating at the heels of an occupant. A footrest system is provided with: a reclining device that rotates an upper end part side of a seatback in the direction of arrow A and holds it at a predetermined angle of rotation; and a slide device that slides a front seat in the direction of arrow B with respect to a vehicle body floor. When an occupant seated in a rear seat uses a footrest portion of the seatback, the reclining device is operated and the upper end part side of the seatback is inclined toward the vehicle front side. Further, the slide device is operated and a slide portion of a seat cushion is moved in a vehicle front-rear direction along a rail portion.

An apparatus and method suitable for producing a polymer film, particularly a polyimide film, perform drying and heat treatment using a tenter type feeding apparatus that suppresses the problems of deformation of film in the vicinity of pore into which the pins bite and breakage of the pores to form long pores in the width direction. The apparatus includes a device to suppress deformation of the film in the vicinity of the tenter pins at the time point when the both ends of the film is pierced with the pins and cools the pin temperature to less than 180° C. at the time when the film is pierced with the pins. Individual pins can be arranged on the innermost side of the pin sheets so that they are all disposed at the same distance both in the film feeding direction in the individual pin sheets and between other pin sheets.

When an action for turning off the power of a host computer is performed, the host computer transmits control information to a disk drive to the effect that chucking should be canceled. Accordingly, the disk drive cancels chucking of a disk and transmits information to the host computer to the effect that cancel has been completed. Receiving the information to the effect that chucking has been canceled, the host computer terminates a disk drive application, confirms that all of the started applications are completed, and then terminates OS (Operating System).
摘要:
A process for conveniently and efficiently producing a highly pure cinnamaldehyde derivative, for example, (2E)-(3-hydroxy-4-methoxy)cinnamaldehyde, which comprises reacting a benzaldehyde derivative, such as isovanillin and the like, with acetaldehyde in the presence of an alkali, in particular preferably, dropping acetaldehyde little by little thereto in an aqueous solution at a low temperature for the reaction thereof. The cinnamaldehyde derivative thus obtained is selectively reduced to produce 3-(3-hydroxy-4-substituted (with methoxy group or the like)phenyl)propionaldehyde. Further, through a reductive alkylation reaction of the compound thus produced with an aspartame, N-[N-[3-(3-hydroxy-4-substituted (with methoxy group or the like)phenyl)propyl]-L-aspartyl]-L-phenylalanine 1-methyl ester, which is useful as a sweetener having a high sweetening potency, can be industrially and efficiently produced. The processes therefor are also provided.

A code reader for color images, which can simultaneously accept a one-dimensional code or a two-dimensional code and data of a color image of a subject for management and which can record both the data in mapping with each other, is provided. The code reader comprises color image pickup means for picking up a code and also a color image of a subject for management as is specified by identification information contained in the code; code-recognizing-data extraction means for extracting luminance data from the color image data picked up by the color image pickup means, and for writing gray scale data into a first frame memory as data for recognizing the code; and recorded-image extraction means for extracting color data from the color image data picked up by the color image pickup means, and for writing the color data into a second frame memory as data for the original image of the subject for management.
摘要:
An optical pickup has a semiconductor laser having two laser sources of different wavelengths disposed in the same package, one diffraction grating and one optical detector. A plurality of light reception areas each having four divisional light reception planes of a -character shape are disposed at positions where light beams reflected from an optical disc are applied. A focus error signal is generated by an astigmatism method by using independently these light reception areas and a tracking error signal is generated by a differential phase detection method by using one or both the light reception areas.
摘要:
It is desirable to greatly reduce the disturbance that arises in a focusing error signal by a astigmatic detection method and offset that arises in the tracking error signal by a push-pull method when reproducing various information storing disks, such as a DVD-RAM disk. It is also desirable to provide an optical disk apparatus which is able to reproduce a variety of high density optical disks, such as DVD-RAM and DVD-ROM disks, as well as conventional disks, such as CD, CD-ROM, CD-R disks, by using a simple optional head. For this purpose, an optical disk apparatus irradiates three optical beams produced by a diffraction grating on the specified position of an optical disk and detects reflected light using a specified optical detector divided into twelve parts.
