Title: Digitizer
Inventor: SATO HIDEKI
IPC: G06F3/048
Filed: 1990-02-15
Abstract: PURPOSE:To enable a person other than an editor to independently use a copying machine for another purpose during the editing work by providing the storage function and the display function of picture data. CONSTITUTION:An input part 5a (input pen) to which picture data of a document from a copying machine 1 is inputted, a storage part 61 (IC card) where picture data inputted to the input part 5a is stored, and a display part 4 which displays picture data in the storage part 61 on a tablet 3 are provide. At the time of editing a picture to be copied, picture data of the document preliminarily read in by the copying machine 1 is not only inputted to a digitizer 2 but also stored, and it is displayed on the tablet 3. Consequently, the digitizer 2 can be used independently of the copying machine 1 to perform the editing work by itself. Thus, a person other than the editor can independently use the copying machine 1 for another purpose during the editing work.

Title: Refractory material for nozzle comprising alumina-carbon
Inventor: NISHIKAWA MASAMI
IPC: B22D41/54
Filed: 1988-02-17
Abstract: PURPOSE:To provide the title refractory material for nozzle having high resistance to spalling and corrosion, etc., as well as superior durability by mixing a specified proportion by weight of carbon and silica with alumina having a regulated particle size distribution, and kneading the mixture, molding the kneaded product, then calcining the molded product. CONSTITUTION:(A) 5-45wt.% carbon (e.g., graphite), and (B) 0.5-40wt.% silica, are mixed with (C) residual wt.% alumina having a particle size distribution consisting of 30-60% fine alumina powder having <=45mum particle size. A refractory material for nozzle comprising alumina-carbon is produced by kneading the mixture, molding the kneaded product, then calcining the molded product. The carbon is dispersed uniformly in the mixture since a tendency for forming coarse particles is given to the alumina by restricting the proportion of fine particles in the alumina to a fixed amt. Carbon bonds are formed uniformly among alumina particles is a matrix. Moreover, generation of mullite due to a reaction with silica is retarded by the generation of coarse particles of alumina.

Title: Gas analyzer
Inventor: NOBUCHI YOSHIAKI
IPC: G01N21/76
Filed: 1991-02-28
Abstract: PURPOSE:To enable sample gas taken from a plurality of sampling points to be measured on a real time basis by changing the sampling frequency of a detector, depending upon the magnitude of output values detected during a certain period. CONSTITUTION:A microcomputer 20 normally selects each of solenoid valves 7, 8, 9 and 17, according to a constant selection cycle, and selectively connects each sampling channel to an analysis channel 23 in order of S1, S2, S3 and 25. In this case, for example, when sampling output exceeds the predetermined threshold value, upon selection of the channel S1, the first timing control program of the computer 20 causes an increase in channel selection cycle, for example, by three times without any change in sampling cycle of the concerned sample gas. As a result, the solenoid valves follow a selection sequence in order of 7, 8, 8, 8, 9 and 17. Consequently, a sampling frequency for the channel S2 trebles and the fluctuation of real time output values is recorded in a recorder 15. Also, necessity for similar timing control is judged at every channel selection.

Title: Solid state area sensor
Inventor: TANAKA SHIYOUICHI
IPC: H04N5/335
Filed: 1984-02-25
Abstract: PURPOSE:To transfer the charge with high stability by changing a low potential to a high potential for a transfer electrode after transferring the charge to the place under a directional transfer electrode adjacent to the downstream side and receiving the charge transferred from a directional transfer electrode at the upstream side. CONSTITUTION:For a 1E/B type CCD area sensor, a vertical CCD6 has directional transfer electrodes OVTG3 (U-Z). The 1st transfer electrode TAG4A is set between the 3Z and the 1st horizontal CCD5A. Now the 3Z is set at a potential VL and the Q1 is transferred to the CCD5A from a place under the 3Z via the TAG4A. Then the 3Z is set at a deep potential VH, and the 3Y is set at a shallow potential VL respectively. As a result Q2 is transferred to a place under the 3Z. While both 3Z and 3X are set at VL with 3Y and 4A set at VH respectively, and the Q2 is transferred to a place under the 5A. While the Q3 is transferred to a place under the 3Y. Thus each signal charge is transferred vertically and therefore electrodes OVTG3 (U-Z) are connected to each output node of a shift register 2A. Then the electric charge is transferred with high stability.
