Title: Feed water pump turbine controller
Inventor: HOSAKA HIDEO
IPC: F01D15/08
Filed: 1978-04-28
Abstract: PURPOSE: To follow a feed water increase demand signal instantly by providing a preceding revolutional frequency setter which controls a steam regulation valve to open or close at a signal of load cut-off.  
     CONSTITUTION: When load is cut-off, a feed water increase demand signal E is put to a velocity setter 1 and a load cut-off signal LE is to a preceding revolutional frequency setter 8 to act a steam regulation valve 4 at a specified opening by a regulation valve oil cylinder 3 so that the steam regulation valve 4 can follow the feed water increase demand signal E instantly. While the cut-off signal LE makes the regulation valve 4 gain specified opening, the signal E is added to vary the output signal of the setter 1 gradually until its signal becomes equal to the output signal of the setter 8 when the output signal of the setter 8 is cut. Then a turbine 6 and feed water pump 7 are controlled in each revolutional frequency by a deviation signal ΔE between the setter 1 and turbine revolutional frequency setter 5.

Title: High voltage generating device
Inventor: SOBU MAKOTO
IPC: H01F19/04
Filed: 1982-03-29
Abstract: PURPOSE:To obtain a high voltage generating device that has high performance and high reliability by dividing secondary voltage into two parts and lowering  the voltage of output pulses and at the same time grounding the middle point of coil in order to avoid addition of DC high voltage output to the divided secondary coils. CONSTITUTION:Divided secondary coils 4A and 4B are wound in the same direction and they are connected in series with grounding at their central point. In this circuit negative secondary output pulse e1 is generated at the beginning of winding of the secondary coil 4 and positive secondary output pulse e2 with the opposite polarity is generated at the end of winding. If the numbers of windings in the divided secondary coils 4A and 4B are the same, both output pulses, e1 and e2, have the same voltage value but opposite polarities. By voltage double rectification the terminal voltage Ec1 for a first condenser C1 is (e1+e2), and the terminal voltage Ec2 for 2nd condenser C2 is (e1+e2)+(e1+e2), and the terminal voltage for Ec3 for third condenser is 2(e1+e2)+(e1+e2). Since with this arrangement the pulse output voltages e1 and e2 can be 1/2n of required high voltage output EH, pulse output can be reduced a great deal, making it possible to realize high order tuning. Performance and reliability is thereby improved.

Title: Line sensor camera
Inventor: KOKUBO MAKOTO
IPC: H04N5/225
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To accurately monitor the recessed and projecting status of an entire object by picking up the image of a traveling object where linear light is applied at a fixed angle from a fixed position by a line sensor and storing output for each line in a memory for each lapse of time. SOLUTION: A line sensor 1 picks up the image of a product 6 traveling on a belt conveyor 6 at a fixed angle from a fixed position. A slit laser 2 applies linear light to the product 6. A one-dimensional/two-dimensional conversion device 4 and an image-processing device 5 take in output for each line of the line sensor into an image memory as information on a direction (Y direction) for crossing the traveling direction of the product 6. In this case, linear light applied to the object by the slit laser 2 is in parallel with the image pickup line of the line sensor 1 and crosses the target position of the line sensor 1. Since height from the belt conveyor 3 can be arbitrarily set by changing the application angle of the slit laser 2, the image can be picked up by the line sensor 1 only if the product 6 has a proper height.

Abstract: PURPOSE:To reduce the pressure drop in a permeated water passage without deteriorating the pressure withstanding property, by arranging units each obtained by bundling plural squeeze-resistant warps in parallel and apart from each other, extending the units in the flow direction of permeated water, weaving the unit with a thin woof, tying the unit to obtain a permeated water passage member, and using the member. CONSTITUTION:The warps each consisting of a thick core yarn 13 and a side yarn 14 and having squeeze resistance are bundled to form one unit 12. The units 12 are arranged in parallel and apart from each other, and each unit 12 is woven by a woof 15 thinner than the warp and tied so that each unit 12 is not collapsed. The permeated water passage member 4 is placed between semipermeable membranes 2 and 3 so that the warp is extended in the flow direction of the permeated water. Under such constitution, a straight permeated water passage is formed between the units 12 and in the gap in each unit 12. Since the woof 15 orthogonal to the straight passage is thin, the flow resistance to permeated water is reduced.

Abstract: PURPOSE:To reduce backlash by dividing a slide piece so as to have two planes and providing elastic members on the contacting parts of said two planes to prevent the generation of a gap between a parallel groove and said slide piece, in an Oldham's coupling having said slide piece inside. CONSTITUTION:A slide piece 13 is divided into two parts so as to have two planes 29, 30 which are parallel to a rotating axis direction (m) while perpendicularly intersecting to each other and a plane 31 which perpendicularly intersects to the rotating axis (m).
