Title: Manufacture of film reeled product
Inventor: HIRANO HIROSHI
IPC: B65H18/28
Filed: 1985-12-09
Abstract: PURPOSE:To prevent the occurrence of a defect, e.g., wrinkles, on the surface layer of reeled products, by a method wherein, in a film reeling final process, a protection sheet is wound at least one round in a state to superpose the protection sheet with the film without relieving tension on the film. CONSTITUTION:In a final process wherein a film is reeled in a roll, a protection sheet is reeled in a state to be superposed with the film. In this case, the thickness of the protection sheet is preferably about 1.5 times as thick as the film. The protection sheet must be reeled in at least one round, preferably two rounds. Further, during reel-in of the protection sheet, it is essential that the protection sheet is superposed with the film in a stretched state without bringing the film into a non-stretching state in that the film is slacked. As a result, reeled products protected by the protection sheet are prevented from having a surface defect, and prevented from production of wrinkle with time due to moisture absorption even if it is left standing for a long time.

Title: Device for designing free curve
Inventor: TSUJITA TAKASHI
IPC: G06T15/00
Filed: 1991-10-23
Abstract: PURPOSE:To form a smoothly continued free curve by forming a curve passing a control point, directly controlling the curve and gradually continuously forming the curve. CONSTITUTION:A curve is grasped as a graphic continuing semicircles consisting of plural auxiliary lines and plural curves by connecting between end points of the curve concerned, between the end point and an inflection point and between two inflection points by auxiliary lines without grasping the curve concerned as a single curve. Then the curve part of each semicircle is regarded as a distorted curve in a normal curve, e.g. a sine function and an elliptic function, and a phase difference curve expressing the degree of distortion of the curve part against the normal curve is found out. Both the end points of the curve part, a maximum displacement point (a point maximizing a distance from each auxiliary line) and an inflection point are used as control points and coordinate values are applied to respective points, so that a curve passing respective control points and having a prescribed distortion is formed and a free curve can be formed with easy fairing.

Title: Image stabilizer
Inventor: ISHIJIMA TOSHIHISA
IPC: G03B5/00
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To stabilize the behavior of a gimbals suspension means of an image stabilizer in starting turning control after widening detectable vibrations to a low-frequency region by increasing the gain of a feedback loop based on an angular position before the prescribed time elapses after the turning control of the gimbals suspension means is started. SOLUTION: The gain of the feedback loop is increased by increasing an amplification factor to the value detected by a position sensor before the time Δt elapses after the turning control of the gimbals suspension device is started. As a result, the behavior of the gimbals suspension device in starting the turning control is stabilized even when the time constant of a CR circuit disposed on the output side of an angular speed sensor is set at a value as large as the vibrations of the low-frequency region like those of camera movement may be detected. The smooth transfer to the image stabilization control is thereby made possible without losing the observation object.

Title: Output circuit for chrominance component
Inventor: ISOBE AKIO
IPC: H04N9/72
Filed: 1985-12-10
Abstract: PURPOSE:To economically suppress the variation of black level on a cathode side, by providing a feedback circuit which feeds back a voltage value proportional to a discharging current value in a horizontal period or a discharging current value to a video amplifier and compensating the amount of voltage drop in a discharging path by means of the feedback circuit. CONSTITUTION:The discharging current Idc of a capacitor C1 flows to the emitter of a transistor Q1 through a power source VAA, resistance RL, capacitor C1, and diode D1. However, a components If which accounts for most of the current Idc is fed back to the emitter section of a transistor Q0 in a video amplifier 1 through the collector of the transistor Q1. Therefore, the collector current of the transistor Q0 is reduced by the quantity of the feedback current If and the output voltage Vout of the video amplifier 1 is raised by IfXRL. If the amplification factor hf1 of the transistor Q1 is set at a large value, the overall variation of black-level potential DELTAV can be controlled to a sufficiently small value having no practical problem even if a resistance value R0 is a large value. Therefore, the black level can sufficiently be stabilized.

IPC: F16K35/00
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent a flow control valve from vibrating and becoming unstable by influence of a flow force generated in the main oil line. SOLUTION: A flow control valve is composed of a proportional solenoid 5; valve element 7 which moves toward a spool 4 on the basis of an excitation force by the solenoid 5; an elastic compressing elastic member 8, located between the valve element 7 and the spool 4; and a pilot oil supplying device supplying a pilot oil to make the opening of the valve element 7 increased as the valve moves nearer toward the spool 4, and to push the spool against the direction of the excitation force. When the spool 4 is moved owing to the disturbance caused by the flow force, the opening of the pilot oil supply means is changed by the movement of the valve element 7, accompanied by the change in the energizing force of the elastic compressing member by the movement of the spool. The spool moved with the flow force moves, thereby, to the reverse direction by change of supply amount of the pilot oil.
