Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To improve product yield by filling a gap having its dimension set via a ceramic coating formed, at least, on a surface of one electrode with electron emission materials. SOLUTION: An electrode 12 is arranged in parallel to an electrode 11 via a gap G. An electron emission material 14 is stuck and formed in a superimposed part of the electrodes 11, 12. The dimension of the gap G between a pair of electrodes 11, 12 is set via a ceramic coating 13 formed, at least, on a surface of one electrode 11. That is to say, the dimension of the gap G is extremely easily and accurately managed by controlling the thickness of the ceramic coating film 13. The gap G is filled with electron emission materials 14 so that the consumption of the electrodes 11, 12 can be prevented by setting electric resistance of the gap G under discharge to sufficiently small and the generated Joule's heat to small.

Title: Data flow arithmetic circuit
Inventor: IWASHITA MASAO
IPC: G06F15/16
Filed: 1988-05-31
Abstract: PURPOSE:To prevent the overflow of a data queue memory by giving the higher priority to the reading of the data queue memory than the reading of a generator queue memory and sending the interim result back to the inlet of the generator queue memory. CONSTITUTION:No data is read out of a generator queue memory 3 as long as just a single piece of data to be read out remains in a data queue memory 4. Thus the memory 4 is read out first. In other words, the memory 4 has the higher priority than the memory 3 in a read mode. The data read out of the memory 3 are used for production of a piece of data within a computing element 6 and the number of produces series are decreased. Thus the operation is through when said decrease value is equal to 0. While the interim value, the increase value and the number of produced series are written again into the memory in case the decrease value is not equal to 0. Thus the decentralization of load is secured and the stable control of data quantity is facilitated.

Abstract: PURPOSE:To obtain a digital signal of a sampling frequency and an analog signal of high quality in a simple constitution by extracting the sample data for each special number after over-sampling it up to a prescribed frequency and at the same time giving the D/A conversion to the extracted sample data. CONSTITUTION:An FIR filter 1 and a linear interpolation filter 2 are used as the means which over-samples an input digital signal of a sampling frequency f1 to convert it into a sampling frequency of (MXkXf1).

Filed: 1987-05-29
Abstract: PURPOSE:To obtain a sharp image free of blur, unsharpness and taint by exposing an image in a position where a curl of film being stable in a transverse direction can be corrected. CONSTITUTION:While regulating the leading edge of an image area on a negative sheet arrives at an exposing position A, an optical system starts scanning. With respect to the negative sheet, both ends outside the image area are held by a belt 29 and a drum 28, all of them rotate together, are turned around by about 180 deg., following which the sheet is conveyed by intermediate rolls 27 and 26 until its leading edge hits a developing roll 30. The intermediate roll 27 is provided with an overrun mechanism, and the negative sheet is conveyed on an exposing drum with tension. By winding the film onto the drum 28, its curl is corrected to bond it to the exposing drum 28, whereby the length of an optical path up to the surface of the negative film and conveying speed can be kept constant. Since exposure is carried out in such a position, namely, an image is exposed with the film stabilized, blurring and unsharpness accompanied with exposure can be prevented.
