摘要:
A process for forming a glass sheet, which is a process for continuously forming a glass sheet, and which comprises a step of introducing a vapor film-forming agent, which is not vapor at least around room temperature and which is vapor at a temperature above the glass transition point of the glass, into a support composed of a structure or a material capable of internally containing liquid, and a step of sliding the support and the glass of which temperature is above the glass transition point against each other via a thin layer of a vaporized vapor film-forming agent.

An electronic photography system which displays an image shot by an electronic image capturing unit. The electronic image capturing unit includes an optical path, an image pickup for converting a focused image to electronic image data, an information inputting device for adding attribute data to the image data, and a storage for storing the image data and attribute data in mutually associated relationship. The system further includes the unit for classifying the image data on the basis of the attribute data for grouping the image data into album groups, and selecting, the album group to display the image data included in the selected album.

An optical recording apparatus includes an optical system to focus a beam of light onto an optical recording medium; a laser source to generate the beam; a laser driver that modulates the output of the beam according to digital information to be recorded; and a controller that performs control in such a way that the average power per unit recording time of the beams used to record digital information "1" (or "0") and digital information "0" (or "1") onto the recording medium are virtually equal, and so that the peak power of the beams used to record the digital information "1" (or "0") and the digital information "0" (or "1") differ from each other.
摘要:
A variable readout signal with at least one reference level to obtain digital data having two or more values. Based upon demodulated digital data, a standard level having two or more values is caused to change following the level of a readout signal having two or more values, and the reference level is changed based upon the change of the standard level.

A focus error detecting method and an optical head using it. In the focus error detecting method, a light beam is emitted from a light source, the beam is given positive and negative astigmatism by a diffraction grating or an acoustooptic element in a focusing optical system, beams thus formed are focused on an information recording surface, the beams reflected from the information recording surface are received by photo-detecting elements in separated optics, the reflected beams with positive and negative astigmatism are compared with each other to take a difference in a focus error detecting circuit, and a focus error detecting signal is obtained on the basis of the difference. The focus for the optical head can be adjusted using the focus error detecting signal.

A signal processing method for recording and playing back recorded data with decreased detection errors originating from residual marks characteristic of an overwrite medium is performed by 8/9 modulating input data, and by inverting the polarity of the modulated data string at each "1" bit to produce a DC-free recording pulse. The thus-recorded signal is played back through a playback equalizer 8 before being converted by an A/D converter 9 into digitized amplitude data. The digitized data are processed to determine an identification level, which identification level is stored as well as used to determine displacement quantities for quantized bits derived from the analog playback signal. The number of "1" bits is counted by a counter 20, and an error in the number of "1" bits is detected by a comparator 21. An error bit decision circuit 22 determines which bit is most likely to be erroneous on the basis of displacement quantity, and the likely erroneous bit is corrected prior to outputting the data for 8/9 demodulation.

The novel antitumor antibiotic designated herein as BU-3420T is produced by fermentation of Micromonospora chersina strain M956-1 (ATCC 53710). BU-3420T and its triacetate derivative possess antibacterial and antifungal activity and also inhibit the growth of mammalian tumors such as P388 leukemia in mice.

An apparatus for positioning and holding a photosensitive material comprises: a case provided movably in a back-and-forth direction on a transparent plate held on a table frame of a copying apparatus; an overlay sheet to be spread over the photosensitive material, having one end fixed to a rear end of the transparent plate and another end held by a sheet roller in the case in a yieldable and retractable manner; stopper members provided on the table frame for placing the case in a desired position in the back-and-forth direction; contact members held by the case for positioning the photosensitive material in a transverse direction, with which at least two right-angled edges of the photosensitive material are brought into contact; and an evacuating device for evacuating air trapped between the overlay sheet and the transparent plate after positioning of the photosensitive material.
摘要:
A plurality of three-dimensional structure configuring devices, each including an elastic body in which micro three-dimensional structure elements fixed to a substrate member are placed so as to be covered therewith and which is fixed to the substrate member, are placed within a film-like elastic body with the substrate members thereof spaced apart from one another so as to configure a three-dimensional structure. Thereby, the plurality of three-dimensional structure configuring devices can be placed with desired intervals of arrangement and in desired positions within the film-like elastic body and so that various specifications can be addressed.
摘要:
A plurality of micro three-dimensional structure elements each having a movable structure fixed on a sacrifice layer, and fixation portions of the micro three-dimensional structure elements for the sacrifice layer are arranged into a film-like elastic body, and then the sacrifice layer is removed. Thus, a three-dimensional structure in which the individual micro three-dimensional structure elements are arranged independently of one another within the elastic body is manufactured.
