IPC: G06F17/50
Filed: 1992-12-16
Abstract: PURPOSE:To improve the operation speed of a circuit and reduce the power consumption by removing a useless buffer from a logic circuit or replacing a cell which has higher driving capacity than needed with a cell which has low driving ability according to the result of a timing analysis. CONSTITUTION:The timing analysis is taken after the arrangement and wiring of the logic circuit. At the time of this analysis, whether or not there is a timing error is analyzed when the buffer where a clock tree, etc., is present is removed and when the cell having the large driving ability is replaced with the cell with the small driving ability. Consequently, the unnecessary buffer B or the cell Y2 having the higher driving ability than needed caused from the difference between actual wiring length and virtual wiring length in a logical simulation stage are found, the necessary buffer B is removed and the cell Y2 is replaced with the Y1 with the small driving ability. The chip area is not reduced as a result of the removal and substitution, but the operation speed of the circuit is improved and the power consumption is reduced.

Abstract: PROBLEM TO BE SOLVED: To secure time for performing corrective processing and to perform sufficient correction by adjusting the carrying position of recording material so as to change the interval of paper for a recording material carrying body at the time of printing and adjusting the number of carrying paper. SOLUTION: Time for scanning by an optical system scanning part is necessitated within each interval of the paper at the time of copying, so that timing for electrifying an electrifier for sucking is controlled by a controller so as to align and stick transfer paper with/to the reference position mark of a transfer drum 5a (a). Also, the time for correcting the color slurring of an image is secured within the interval of the paper at the time of the printing, so that the timing for electrifying the electrifier for sucking is controlled, and two sticking positions of the transfer paper for the drum 5a are changed from copying time, and the interval of one paper is made larger by gathering the other transfer paper to one side of the drum 5a in a peripheral direction (b).  Thus, the interval of the paper of the recording material at the time of transferring or the interval at the time of forming an electrostatic latent image for an image carrier are adjusted when the correction of the image is required, so that correction time is secured.

Title: Filter for soft x rays and soft x-ray measuring device
Inventor: MASE AKIRA
IPC: G21K3/00
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain a filter for soft X rays with sufficient wavelength selectivity and a soft X-ray measuring device by overlapping two types of thin films, namely a metal thin film and a non-metal thin film with different soft X-ray transmission characteristics. SOLUTION: Hard X rays are eliminated by a metal thin film as soft X-ray constituent, and soft X rays that could not be eliminated by a metal thin film and exceed a specific wavelength region are eliminated by a non-metal thin film, thus obtaining soft X rays at a narrow wavelength region. Metal such as Be, Al, Sc, Ti, and V is used as the raw material of a metal thin film. A thin film made of a macromolecular material such as polypropylene, polyethylene, and polyvinylchloride and a thin film made of such inorganic material as silicon nitride Si3N4 and silicon Si are used as the non-metal thin film. When Al thin film is used as the metal thin film, its film thickness is set to 0.01-0.2 μm. When polypropylene P and P thin film are used as the non-metal thin film, its film thickness is set to 1-5 μm.  In the case of a filter where both of them are overlapped, improved transmission property is achieved with a wavelength of 4-7 mm.
