Title: Method and apparatus for removal of bubble in liquid
Inventor: SAITOU YOSHIHIRO
IPC: A61B8/00
Filed: 1990-01-17
Abstract: PURPOSE:To easily remove bubbles generated in a liquid without moving them by supplying degassed liquid to a container which is filled with a liquid having the same composition as the degassed liquid so as to dissolve and remove the bubbles in the liquid with which the container is filled. CONSTITUTION:A membrane module 5 to degas a liquid 2 with which a container is going to be filled, a liquid sending pump 1 to send a liquid to the membrane module 5, and a pressure reducing pump 6 to reduce the membrane module 5 are installed, and a circulation system is composed of the membrane module 5, the liquid sending pump 1, and the pressure reducing pump 6. That is, bubbles in a liquid with which a container 3 is filled are dissolved and removed by supplying a degassed liquid having the same composition as the liquid to the container filled with the liquid 2. As a result, without moving, the bubbles generated in the liquid are removed easily and, moreover, fine bubbles which are hard to be observed with eyes are also removed.

Abstract: PURPOSE:To easily measure an error with high accuracy by providing a measuring instrument table with slide tables which move a measurement tip terminal horizontally and vertically, and providing a jig for phase matching between the coordinate axes of a gear and the measuring instrument table. CONSTITUTION:While arms 16a and 16b are moved horizontally, spheres 14a and 14b are brought into contact with tooth surfaces 23 and 24, and 25 and 26 without any gap, and the arms 16a and 16b are fixed with setscrews 17a and 17b. Further, a table 4b is moved as shown by an arrow (a) until the measurement terminal 9 abuts on a tooth surface 12 from an optional measurement point P on a tooth surface 11, and the point is denoted as R. The Xm-Ym coordinate system which has the Ym coordinate axis of the tip terminal 9 on the center line of a segment PR and Om at the intersection of Ym and a tooth bottom circle 21 is in phase with the X-Y coordinate system which has it origin O in the center of the gear 10 and its Y axis running at O and Om. The tip terminal 9 is moved from the point P toward the circumferential surface 22 by pulse motors 5a and 5b through the tables 4a and 4b according to points on a normal involute curve to find the tooth profile error from the quantity of the displacement of the terminal 9.

Title: Catalyzer converter
Inventor: HATANAKA TOORU
IPC: F01N3/28
Filed: 1978-01-27
Abstract: PURPOSE: To prevent the catalyser material from damage caused by a dancing motion in the cylinder due to a vibration, by means of tightly supporting the catalyzer material of honey-comb type, using a buffer ring and a ring retaining material, without providing a looseness in the catalyzer converter main unit.  
     CONSTITUTION: A buffer ring 4, intermediately installed for mounting a catalyzer material 3 of honey-comb type, causes no unnatural difficulty in the mounting support due to its elasticity, and absorbing a thermal expansion of the catalyser 3, with no clearance made generating between with a ring retaining material 5, simultaneously, the buffer ring 4 is always pressed at a constant load diametrically and axially by the retaining material 5. Consequently, even for the converter vibrating, the catalyzer 3 never makes a big dancing motion in a cylinder 1, capable of preventing the catalyzer 3 from damage. And the retaining material 5, because of applying a preliminary load to the buffer ring 4 as well as serving a role of the mounting material for the converter main unit cylinder 1, can be made small for the requirement regardless of a length and sectional pattern of the catalyzer 3. Accordingly, the work of drawing of the retaining material 5 will be facilitated.

Filed: 1983-01-20
Abstract: PURPOSE:To enable the dense packing of toner in a recovering box by providing a packing plate which is moved by expansion and contraction of shape memory alloy in a toner recovering box provided inside of a copying machine.

Title: Analog-to-digital converting circuit
Inventor: SUZUKI TOSHIHISA
IPC: H03M1/16
Filed: 1981-01-22
Abstract: PURPOSE:To execute A/D conversion at a high speed and exactly, by connecting in parallel plural differential extractors haiving each different extraction gain, and quantizers provided in accordance with each differential extractor, and selectively operating them in accordance with an input signal. CONSTITUTION:While a variation of an input analog signal Sai is in a low level, a quantizer QRZ2 corresponding to a differential extractor DDE2 whose extraction gain is high converts a variation of the input analog signal Sai faithfully to a quantizing signal Sq2, and it is applied to an adder ADD through a selector SEL. When a level of a variation of the input analog signal Sai increases and overflow of the quantizer QRZ2 occurs, the selector SEL selects outputs of a differential extractor DDE1 whose extraction gain is low and a quantizer QRZ1. Accordingly, even in case of a quantizer having the number of inexpensive low bits, quantization is executed with high accuracy against an input signal extending over a wide range by combining plural pieces.

Then the means 11 allows a transfer rate/transfer start time calculation means 17 to calculate a transfer rate and a pre-fetch start time with respect to non-stream data within a remaining transfer rate being the subtraction of the transfer rate of stream data from the total transfer rate and a transfer rate/transfer start time setting means 18 sets them. Thus, data written by reproduction information ID are reproduced without intermission.
