Abstract: PURPOSE: To perform accurate flow rate control from small to large scale by deviding damper vanes into groups of fixed number of vanes according to the flow rate range to be controlled and by performing opening adjustment of damper vanes in each group.  
     CONSTITUTION: When, for example, applied to a damper device with five damper vanes, five damper vanes 21W25 are devided into two groups of one damper vane 21 and four damper vanes 22W25, each group driven on different driving devices 101, 102.

And, the flow rate control for small flow amount is performed by the opening of only the damper vane 21 for 0° to 90°, and the control for greater flow amount than that is done by sutting the damper vane 21 and simultaneously by operating the damper vanes 22W25.

Abstract: PURPOSE:To simply and inexpensively produce a light shielding mask without affecting transparent electrode patterns, etc., by using a material dissolved or dispersed with such a material as to lower transmittance for a photoinsolubilization type photosensitive compsn. at the time of forming a light shielding layer. CONSTITUTION:A photosensitive layer 50 is formed by using the photoinsolubilization photosensitive compsn. at the time of forming the light shielding layer 5, then the photosensitive layer 50 is exposed and developed in required patterns. Processing to provide light non-transmittability to the photoinsolubilization type photosensitive compsn. is executed before or after this exposure and development. This processing is executed by dissolving or dispersing the material to lower the light transmittance in the photoinsolubilization type compsn. prior to the formation of the photosensitive layer 50. The need for photoetching for the purpose of forming the light shielding layer 50 is thereby eliminated and the product cost is reduced.

Title: Multistage optical isolator
Inventor: TAKEDA SHIGERU
IPC: G02B27/28
Filed: 1987-02-17
Abstract: PURPOSE:To realize a small-sized highly functional multistage optical isolator where the plane of polarization is not rotated, by magnetizing N-number of magnets in the axial direction and arranging magnets so that magnetic poles having the same polarity of adjacent magnets face each other. CONSTITUTION:Cylindrical magnets 3a and 3b' having a thickness L have opposite magnetization directions and are arranged a length (x) apart from each other so that their S poles face each other. Beam spliters P1 and P3' in the incidence side and the exit side are directed to the same direction, namely, the direction of 0 deg., and an analyzer P2 interposed between two Farady rotating elements FR-1 and FR-2' is directed to the direction of 45 deg.. Consequently, the light incident on a point (a) passes the Farady rotating element FR-1 to have the plane of polarization rotated at 45 deg. and passes the analyzer P2 inclined at 45 deg. and is made incident on the second Farady rotating element FR-2'. Since the element FR-2' is magnetized in the opposite direction, the plane of polarization of the light passing the element FR-2' is rotated at 45 deg. in the opposite direction. Thus, the small-sized multistage optical isolator having a large opposite loss is obtained.

Title: Method for measuring plastic sheet width
Inventor: IGUCHI KATSUHIRO
IPC: B29C48/92
Filed: 1987-02-17
Abstract: PURPOSE:To improve the accuracy of width measurement by varying the threshold value of plate end detection according to the thickness of a body to be measured. CONSTITUTION:A thickness gauge which utilizes a beta ray, an infrared ray, etc., is made to scan in a breadthwise direction of a sheet 13 to measure its thickness and also measure the width of the sheet 13 while deciding a position where the thickness measured value varies abruptly as an edge position. Namely, the infrared ray from a light source 26 is absorbed by the sheet 13 and inputted to a detector 29, but if its spot 30 shifts from the edge of the sheet 13, the quantity of light absorption decreases greatly, so the edge position is measured. When the point where the spot 30 meets the sheet 13 at a prescribed rate is regarded as the edge point, the output of the detector 29 at this point differs according to the thickness of the sheet 13. For the purpose, the detector output at the center point is averaged and the half of the value is used as the threshold value to decide the point where the detector output reaches the threshold value as the edge, thereby compensating an error based upon the thickness.

Title: Measurement of creatinine

IPC: G01N27/416
Filed: 1983-03-01
Abstract: PURPOSE:To enable a specific measurement of creatinine alone by removing positive errors due to the presence of creatin utilizing difference in the speed of an enzyme reaction between creatinine and creatin. CONSTITUTION:A curve A shows changes in the current flowing through a hydrogen peroxide electrode when a sample only containing creatin is added to an enzyme solution and a curve B changes in the differentiated value thereof. A curve C shows changes in the differentiated value when a sample only containing creatinine is added. The differentiated value (curve D) of current by a sample containing both creatinine and creatin when the differentiated value of current by creatin zeroes is related to creatinine only. Since the decomposition of hygrogen peroxide by catalase is slow, there ceases increase in the concentration of the hydrogen perioxide in the solution attributed to creatin existing in the sample from the beginning in 90-130sec after the start of the reaction. Thus, it becoms possible to measure the concentration of creatinine in the sample by measuring the differentiated value when 90-130sec passes after the mixing of a liquid containing creatinine in the enzyme solution.
