Title: Apparatus for testing reaction fin
Inventor: CHIBA NORITANE
IPC: B63B71/20
Filed: 1985-03-11
Abstract: PURPOSE:To make it possible to simply calculate lift corresponding to the mount angle of each fin blade, by radially implanting fin blades to the stern boss of a model ship through a mount angle adjusting mechanism and adhering a strain gauge to the strain generating part of the base part of each fin blade. CONSTITUTION:The change quantity in a flow direction by a fin blade 2 corresponds to the lit generated in the fin blade 2 in the relation of action and counteraction. Therefore, by accurately measuring the lift generated in the blade 2 by a strain gauge 5, the mount angle of each blade 2 can be easily and accurately set so as to obtain the change quantity in a scheduled flow direction. By this method, the mount angle of each blade is applied to an actual ship properly determined along with the measured data by the gauge 5. Because the gauge 5 is adhered to a strain generating part 4b formed into a plate shape, the accurate quantity of strain can be measured.

Title: Method for inspecting surface crack of original wire for steel wire for welding
Inventor: TANAKA HARUTOSHI
IPC: G01N21/892
Filed: 1983-03-24
Abstract: PURPOSE:To decide the presence or absence of a very small crack on the surface of an original wire prior to feeding of the original wire to a production stage by subjecting the original wire sample after hot rolling to coiling and pulling and pickling the wire. CONSTITUTION:A sample is drawn from the orginal wire coil of a steel wire produced by hot rolling. The sample original wire is subjected to coiling and pulling and is then pickled with hydrochloric acid by which the wire is descaled. The wire is then rinsed and dried and the surface of the original wire is observed by using a magnifier or the like, by which the presence or absence of a very small crack is inspected and decided. The very small crack on the surface of the original wire is thus preliminarily checked and the production conditions meeting the degree of the crack are selectable and therefore the satifactory steel wire for welding is produced.

Abstract: PROBLEM TO BE SOLVED: To inform a user of the situation when a read character picture cannot be recognized. SOLUTION: The character picture containing a character is taken by permitting the user to depress a picture take-in key 3. The character picture displayed on a display part 2 is segmented. A method used from a former case is used for the processing of character segmenting. The picture elements of the same color for one lateral row are taken out and the total is obtained. The picture elements of a vertical column where the total is large is summed up. The large part is set to be an area where the character exists. When the segmented character picture has a size that can be recognized, the character picture is stored. When the segmented character picture has the small size that cannot be recognized, 'It cannot be recognized' is warning-displayed at the lower left of the display part 2.

When the display control flag of an item key is equal to 1, the inverted display data is sent to a picture memory 8. Then the forward display data is sent to the memory 8 after a fixed time and displayed there. Then the CPU 1 refers to the screen switch information on the item key and specifies the screen to be displayed next based on the page screen No as long as both the screen No and the page No are not equal to 0. The CPU 1 transfers the display data to the memory 8 to display it there after cleaning the memory 8.

Title: Blower device
Inventor: TOMOHIRO TERUHIKO
IPC: F04D17/04
Filed: 1985-03-12
Abstract: PURPOSE:To increase a vane row work amount in a suction area, by a method wherein the upper surface of a guide wall is inclined toward its lower surface part in a way that a distance is decreased on the runner side, and its opposing surface part is widely inclined toward the direction of the tangential line of the outer periphery of the runner. CONSTITUTION:An inclined upper surface part 3a of a guide wall controls a flow running from a level below the upper surface part 3a of the guide wall along the rotation direction of a runner 1, and guides a flow running from a level above a guide wall 3 so that it incomes in a reverse direction to the rotation direction of the runner 1. A contact 3d between an opposing surface part 3c of the guide wall 3 and a lower surface part 3b is separated further away from the runner 1 than a contact 3e between the opposing surface part 3c and the upper surface part 3a. Thus, the opposing surface part 3c has a high angle with the tangential line of the portion positioned facing the runner 1, and a flow along said surface forms a flow which runs in a direction extending nearer to a radial direction than a flow along the outer periphery of a conventional runner 1. A flow in the vicinity of the upper surface part 3a of the guide wall incomes with a peripheral component extending in reverse direction to the rotation direction of the runner 1, and this increases a vane row work amount in a suction area.

Title: Nonlinear amplifier circuit
Inventor: NODA KIYOSHI
IPC: H03G11/08
Filed: 1978-04-27
Abstract: PURPOSE:To ensure the steady operation property through a simple constitution by converting the same signal as the input signal applied to the inverse amplifier circuit into the fixed property through the nonlinear circuit and then applying the converted input signal to the noninverse input terminal of the operational amplifier within the noninverse amplifier circuit. CONSTITUTION:When input signal EI is applied between input terminal P1 and input/output common terminal P2, circuit 2 does not operate in case the relation of ¦EI¦<=¦VZ¦ is obtained between the absolute value of signal EI and Zener voltage VZ of constant voltage diode ZD of nonlinear circuit 2. Thus, offset voltage VOF applied to noninverse input terminal S2 of operational amplifier A in inverse amplifier circuit 1 also becomes zero. So circuit 1 functions as a mere inverse amplifier. Accordingly, circuit 1 functons as a differential amplifier circuit in which voltage VOF proportional to signal E1 is applied to terminal S2 of circuit A. As a result, the operation property which is steady and identical to the conventional operation can be obtained.

IPC: H01J29/04
Filed: 1984-03-14
Abstract: PURPOSE:To obtain images free of wavy lines and luminance nonuniformity by using a lubricated rod having V-shaped grooves to support a cathode wire. CONSTITUTION:Between a cathode wire 1 and a lubricated rod 8 which is fixed to a supporter 10 through a frit 11, V-shaped grooves are formed which consist of a spring-side slant 12 of about 15 deg. and a center-side slant 13 of about 10 deg. so that the cathode wire 1 touches the lubricated rod 8 at one point. Additionally, the R dimension of the top end of the V-shaped grooves is adjusted to be about two times the diameter of the cathode wire 1, so that the positioning between the cathode wire 1 and the lubricated rod 8 is accurately performed while bringing these members into contact with each other at one point. As a result, the static friction between the cathode wire 1 and the lubricated rod 8 becomes 1g or less and the tension variation of the cathode wire 1 is widely reduced. Accordingly, it is possible to make the characteristic frequency of the whole cathode wire 1 different from an integer multiple of the pulse frequency, thereby preventing any resonance.
