IPC: B41N1/06
Filed: 1991-03-28
Abstract: PURPOSE:To easily sharpen edges of intaglios by a method wherein a metallic layer to be formed over a substrate for applying etching thereon to form the intaglios is made so that the composition thereof varies gradually from such that is easy to be etched to such that is hard to be etched as it approaches from the substrate side to the surface side.

The copper-nickel alloy layer 3 is so formed over the nickel layer 2 that the ratio of the nickel to the copper in the layer becomes gradually bigger as it approaches from the substrate side to the surface side. After applying an etching resist 4 to the copper-nickel alloy layer, pattern etching is made to specified depths. After the etching resist 4 is removed, the intaglio is finally formed by applying chromium plating.

Title: Encoding and decoding device
IPC: H04N19/80
Filed: 1992-03-23
Abstract: PURPOSE:To more efficiently compress picture data by adding the circuit which attenuates the characteristic of the frequency band emphasized by an outline compensating circuit in a camera device. CONSTITUTION:The outline compensation characteristic due to a camera device 1 of an input picture signal is smoothed by an attenuating filter circuit 101 with respect to the luminance signal which is considered to include much noise components. Thereby, the picture signal where the power of noise components increased by the outline compensating circuit in the camera device 1 is reduced is inputted to an encoding circuit 102. This circuit 102 takes the output picture signal of the attenuating filter circuit 101 as the input and encodes the picture and compresses it by quantization or the like. In a transmission system 103, transmission line encoding, transmission, and transmission line decoding are performed. A decoding circuit 104 expands the picture signal by inverse quantization, decoding, or the like. An emphasizing filter 105 restores the gain of a frequency band picture signal by a filter which has characteristics to restore the gain of the picture signal component in the frequency band attenuated by the characteristic of the attenuating filter 101.

Title: Trace circuit
Inventor: ITO AKIRA
IPC: G06F11/28
Filed: 1987-03-19
Abstract: PURPOSE:To trace even an event set before a trace trigger point by writing input data into a trace memory at all times and replacing data preceding a time point when the trace is required by a fixed address section. CONSTITUTION:A write enable signal WE is produced from a write timing generating circuit 2 and sent to a trace memory RAM. At the same time, a write address generating circuit 3 produces a write address and sends it to the memory RAM. Thus the input data are continuously written into the memory RAM. When a debug halt request is produced, a trace section setting circuit 1 is actuated by a trace trigger signal TRG and outputs a trace section end signal TRE when the time elapses by an amount equal to the time set value (m). Thus both circuits 2 and 3 have no output and the writing operation of the input data is stopped. Therefore the trace is replaced for a section (m) from a trigger point TRP of an optional address and the previous data are stored in other addresses. Thus the check is possible before and after the point TRP when a monitor address is indicated based on an address of the end of the trace section.

Title: Energy analyzer with filter incident position changing means
Inventor: TSUNO KATSUSHIGE
IPC: H01J49/48
Filed: 1987-03-19
Abstract: PURPOSE:To facilitate the adjustment of a beam by displacing the position where the beam to be measured such as an electron beam enters into a filter from the center and straightly advancing it in the filter in an energy analyzer with the Wien filter. CONSTITUTION:When an electron beam 28 accelerated and having permeated a sample is to be analyzed by an electron microscope or the like, an analyzer consisting of a Wien filter 24 is used. The uniform electric field and the magnetic field are superimposed at a right angle and applied to the beam 28 passing in the filter 24 to allow it to advance straightly. At the peripheral section, the electric field and the magnetic field are not uniform, and the beam 28 is deflected. This is prevented as follows: i.e., the beam 28 is deflected by two-stage deflecting coils 21, 22 and decelerated by a decelerating lens 23 then fed to the filter 24 through a position separated from the optical axis. Next, the beam 28 from the filter 24 is accelerated by an accelerating lens 25 then returned to the optical axis by deflecting coils 26, 27. Accordingly, the beam 28 advances straightly in the filter 24, and the adjustment of the beam is facilitated.

Abstract: PURPOSE: To prevent the spouting of molten metal from an insertion port and prevent danger by providing a cover having the pass hole for a rod to the p lunger insertion port of the sleeve and reciprocating the plunger.  
     CONSTITUTION: The cover body 8 passed onto a plunger rod 6a is fitted to the top end of a sleeve body 5a and is fixed by a set bolt 13.

The paste is a mixture of fatty acid salt (7 carbons and liquid) of ruthenium, respective fatty acid salts of Pb, B and Si, ethylcellulose and terpineol. The portion of the resistance layer is masked and formed with patterns by a solution of ammonium fluoride and sulfuric acid. After the heat generating resistance layer 13 is formed, a paste of a metallic organic compound is printed and baked (800 deg.C) to obtain an electrode layer 12, 6 layers per mm, through photolithoetching. A glass paste is printed and baked above the electrode layer 12, thereby forming an abrasion- proof layer 14.
