Title: Thermal cathode type vacuum gage
Inventor: TAKAGI NOZOMI
IPC: G01L21/30
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To eliminate adverse effect of a photo-electron by providing a repeller electrode for reversing the direction of drawn-out ions, setting a collector elec trode on the grid side and the opposed side of an extraction electrode on the counter position thereto and collecting ions. SOLUTION: Electrons generated on a filament 2 are attracted on a grid 1 at higher potential, and reciprocate in and out of the grid 1 along a spiral orbit. The electrons collide with gas molecular of a space therebetween, it is ionized, ions fly downward from the opening of an extraction electrode 4 of lower potential than the grid 1. The ions reverse the orbit on the repeller electrode 5 and collide with a collector electrode 3. The number of the ions, namely, ion current is measured and pressure of a vacuum vessel is found. An X-ray generated on the grid 1 is shielded by the electrode 4 and does not irradiate the electrode 3, and photo-electron current therefor is not allowed to flow. Photo-electrons generated on the electrode 5 by the X-ray through the openings of the electrodes 3, 4 are returned to the electrode 5, reach the electrode 3, and do not adversely affect.

Title: Filter circuit
Inventor: KOUNO KOUUN
IPC: H03H11/04
Filed: 1987-09-07
Abstract: PURPOSE:To reduce the number of components by setting bases of 2nd and 3rd transistors(TRs) to the same level as the base of a 1st TR in tems of DC. CONSTITUTION:The structure of a voltage division circuit 33 to divide an output signal to supply a voltage division signal to one input section of a 2nd Gm amplifier 32 is far simplified in comparison with a conventional circuit. That is, in applying a DC power voltage VB3 to make the level of the base of the TR Q43 equal to the DC level of the base of the TR Q45, the DC voltage level of TRs Q38, Q39 is kept equal. Thus, resistors R14, R15 are operated for voltage division and simultaneously are used as elements to constitute the input circuit of the Gm amplifier and the number of elements to be added for voltage division is very less.

Title: Data compressing device
Inventor: WATANABE TORU
IPC: H04N7/30
Filed: 1992-07-29
Abstract: PURPOSE:To reduce a circuit scale and to improve arithmetic precision by replacing the coefficient of a data conversion arithmetic means with an integer ratio and permitting a quantizing means to adjust gain change generated by means of changing into an integer ratio. CONSTITUTION:An operation by the two coefficients being COS(2/16)pi and COS(6/16)pi is required in order to obtain the arithmetic output F6' of a butterfly arithmetic part 131. These values are indicated as two infinit decimals being 0.923... and 0.3826.... The ratio of COS(2/16)pi with COS(6/16)pi is approximated by the ratio 5:2 and the operation is executed by the value obtained by replacing the arithmetic coefficient with the integer ratio. Then, gain change generated by replacing the arithmetic coefficient with the integer ratio is absorbed by the quantizing part. Thus, the arithmetic bit width of a data converting part is drastically reduced, therefore, the circuit scale is sharply reduced.

Next, multiplication of a multiplier b1 and a multiplicand A is made and inputted to multipliers s-1-s-4 (a-2). In such a case, the input of partial product is being shifted to the left by 8 bits, accordingly, shifting to the right of SUM1 and CRY1 becomes unnecessary (b-2) when making addition of partial sum SUM1 and partial carry CRY1 obtained previous time by CSA. Similarly, a-3, b-3, a-4, b-4 are executed and finally, the addition of SUM 4 and CRY 4 are made by CPA, and terminated.

Title: Manufacture of ag/ag halide electrode
Inventor: TOKUNAGA HIROMITSU
IPC: G01N27/30
Filed: 1987-09-07
Abstract: PURPOSE:To enable accurate measurement of the concentration of a sample liquid, by using an elctrolytic liquid with an organic ligand added thereto to form an Ag/Ag halide electrode. CONSTITUTION:An electrolytic tank 2 holding KCl (potassium chloride) contain Cl<-> as electrolytic liquid 3 is filled with an organic ligand having phenanthroline added thereto as such being able to form Ag ions (Ag<+>) and complex ions. Ag5 and Pt4 are immersed in the electrolytic liquid 3 and connected to an anode and a cathode of each electrolyzer 1 to perform an electrolysis treatment. As a result, an AgCl sensitive layer 6 is formed on the surface of Ag5 while phenanthroline reacts with the Ag ions, and hence, the sensitive layer 6 is formed being fixed in a complex type with a high molecular weight whereby a pinhole is sealed up with these complexes of a high molecular weight. Thus, the use of an Ag/AgCl electrode produced as ion selective electrode prevents a drop in the sensitivity with the supporession of possible concentration contamination between sample liquids.

Title: Mounting structure of flexible printed circuit board
Inventor: FUJIWARA YUTAKA
IPC: H05K1/14
Filed: 1987-09-08
Abstract: PURPOSE:To increase the degree of expansion and contraction of an FPC board and reduce the entire length of the same upon housing of the same by fixedly mounting the FPC board at one points of respective members and forming a U turn part which moves responsibly to the relative movements of the members such that the U turn part is housed at a special position where the relative distances among the respective members become minimum. CONSTITUTION:In an expansion and contraction device including electric parts 9 composed of members 6-8 which relatively parallelly move and require power supply, an FPC board 1 has U turn parts 1a and 1b move parallely to the direction of the members 7 and 8 as those members 7, 8 move. The FPC board 1 is fixedly mounted on the respective members 6-8 respectively at respective points 6a-8a. As the longitudinal relative distances among the respective members 6-8 approach zero, the U turn parts 1a, 1b of the FPC board 1 come together to a special one point. Such zero relative distances among the relatively moving members allow, whatever the number of those members is, all the U turn parts to gather to the special point, thereby minimizing the length of the FPC board extending in the direction of the movement of the members.

Inventor: ONO ATSUSHI
IPC: B41J2/28
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To vary the printing force depending on the thickness of a print medium without increasing the power consumption at the time of driving a print wire by providing means for varying the amount of flux passing through a magnetic by-path depending on the thickness of a print medium thereby varying the printing force of print wire. SOLUTION: The core 1 of a wire dot print head is magnetized by the flux of a permanent magnet 3 and when a current is fed through a coil 2 in the direction for generating the flux reversely to that of the permanent magnet 3, attraction force of a core pole 1' is decreased and a print wire 8 is driven. More specifically, a bypass ring 11 built in a print dot 104 is turned to vary the relative position with respect to a bypass ring 10. When the cross-sectional area increases at the overlapped part of bypass springs 10, 11, the amount of flux passing through the bypass springs 10, 11 increases and the amount of flux passing through the core 1 decreases. Consequently, the force for attracting the armature 6 is varied and thereby the printing force is varied.
