Title: Winding tension control device
Inventor: KATAOKA AKIRA
IPC: B65H23/198
Filed: 1985-10-06
Abstract: PURPOSE:To enable measurement of winding torque by the use of a simple and reliable means, by a method wherein the driving reaction force of a prime mover for driving a winding shaft is determined by means of a road cell, and further, a tension value is determined by dividing winding torque by a winding size for feedback. CONSTITUTION:A prime mover 4 rotates and drives a winding shaft A through a pulley 9 and a belt 10, and when a sheet is rolled, a reaction force, simultaneously, is detected by pressing a road cell 7, mounted to a braking body 6 of a winding shaft retainer 1 body, by means of a prime mover mounting frame 5. The reaction force is determined as winding torque by multiplying it by a distance between a prime mover mounting frame 5P and the road cell 7, and is determined as the tension of the winding sheet by dividing it by a winding size calculated by an electric control part. The electric control part performs feedback control of rotation driving of the prime mover 4 so that the tension is maintained at a constant value. This enables direct measurement of winding torque, i.e., tension, during winding through a simple and reliable means.

Title: Speed detecting method for discrete system
Inventor: OZAKI FUMIO
IPC: G05B21/02
Filed: 1989-08-31
Abstract: PURPOSE:To detect the speed with high accuracy by shortening (elongating) a sampling period for detecting position data at the time of a high (low) speed. CONSTITUTION:Samplers 6a, 6b are samplers of position signals inputted to a position detecting part 4 and a computer 9 for calculating a speed, and start an operation for obtaining position data of a discrete system at every prescribed period by a signal sent from a sampling period signal generating means. A detecting part 4 detects position data p1, p2 of the discrete system at the time t1, t2 obtained through the sampler 6a at every sampling period, sends the obtained position data p1, p2 to a speed calculating part 9, and calculates a speed V by V = (p1 - p2)/(t1 - t2). In this case, the sampling period of the sampler 6a is varied in accordance with a motion of a measuring object. That is, by elongating the sampling period at the time when a variation rate of the position data is low, and reducing it at the time of a high speed, the speed detection is executed with high accuracy.

Abstract: PURPOSE: To keep a water quality at a proper value at all times without reducing flow rates of feed water and condensate by providing a first injection piping having a check valve extending from a low pressure drain pump to an upstream side of a condensate desalting apparatus and a second injection piping having a check valve extending to a downstream side of the condensate desalting apparatus. CONSTITUTION: In ordinary operation, a check valve 36 of a second injection piping 35 is fully closed, and low pressure feedwater heater drain is injected into upstream side condensate in a condensate desalting apparatus 31 through a first injection piping 32. Hereby, the low pressure feed water heater drain is passed through the condensate desalting apparatus 31 to keep a water quality at a proper value. In contrast, when there happens seawater leakage in a condenser 26, the check valve 36 of the second injection piping 35 is fully opened, and a check valve 34 of the first injection piping 32 is fully closed to change over an injection point. Hereby, there is ensured redundancy of a flow rate for the condensate desalting apparatus 31, and hence continuous operation of a plant is ensured also against happening of seawater leakage.

Title: Hot-line insertion circuit
Inventor: FUJIE TOSHIAKI
IPC: H02H9/02
Filed: 1994-09-19
Abstract: PURPOSE: To restrict the feeding to a printed board and increase the feeding to the printed board with the passage of time and finally maximize the feeding to the printed board by inserting a saturable inductance in a line to connect a power input terminal and the printed board. CONSTITUTION: When a printed wiring board 3 is connected to a positive terminal 2a and a negative terminal 2b of a connector 2, a positive input terminal 2c is connected to the terminal 2a and a negative input terminal 2d is connected to the terminal 2b and then the printed wiring board is electrically connected. When the printed wiring board is inserted into the line, the output current of a DC power supply 1 flows in a loop of a positive output bus 1a → the terminal 2a → the terminal 2c → a saturable inductance → a logic circuit 4 → the terminal 2b → a negtive output bus 1b. Therefore, the feeding can be restricted by means of a high impedance at the time of rising of current of the saturable inductance 5.  After inserting a hot line, the impedance of the saturable inductance 5 becomes small with the passage of time and thereby the feeding to the printed wiring board 3 can be increased and finally maximized.

Title: Method for impregnating solid material with liquid binder
Inventor: BARUTAA AIRITSUHI
IPC: B01F13/06
Filed: 1991-09-03
Abstract: PURPOSE: To effectively impregnate solid materials with a liquid binder by making the pressure above the atmospheric pressure after the liquid binder is supplied under a vacuum condition while mixing the granular or powdery solid materials within a mixing chamber.  
     CONSTITUTION: The powdery and granular solid materials such as coke carried-in with a screw conveyor 2 are charged into a vacuum mixer device 1 after preheated with a current heating device 3 equipped with electrodes 4, 5, as necessary. At this point, the powdery and granular materials are evacuated with a vacuum pump 7 via a condenser 8 while mixed. A liq. such as tar or a binder which is liquefiable by heating is supplied in the specific amt. from a weighing apparatus 6 to the vacuum mixer device 1 and is further mixed, after preheated as necessary under this vacuum condition. Thereafter, the pressure inside the vacuum mixer device 1 is raised more than the atmospheric pressure. As a result, after the air within circular openings of the solid materials are removed under a vacuum, the liquid or liquid binder infiltrates thereinto, effectively impregnating the solid materials.

Title: Three-dimensional spiral antenna
Inventor: MIKAWA TAKAO
IPC: H01Q21/24
Filed: 1989-08-31
Abstract: PURPOSE:To form the antenna which radiates circularly polarized waves all directions by arranging three spiral antennas which are each expanded on a plane on three mutually orthogonal planes respectively. CONSTITUTION:The three spiral antennas 1, 7, and 14 which are expanded on the plane are arranged on the three mutually orthogonal planes while having a common feed point. This three-dimensional spiral antenna 10 when viewed e.g. in the (x)-axis direction of a coordinate system has characteristics similar to those of a plane spiral antenna which is expanded on a y-z plane. This results from that electromagnetic waves from spiral antennas which are expanded on an x-z plane and an x-y plane interfere with each other because the plane spiral antenna radiates the circular polarized wave in the front direction, but does not radiate the circular polarized wave in side directions. Therefore, the circular polarized wave can be radiated in all directions.

Title: Cold cathode fluorescent lamp
Inventor: TSUNEKAWA SHINICHI

Filed: 1989-08-31
Abstract: PURPOSE:To reduce tube wall blackening of an effective light emitting part so as to heighten the brightness by forming a pair of cold cathodes in the shape of spreading in the opposing direction. CONSTITUTION:Since the shape of a pair of cold cathodes 13 to be housed inside both axial end parts of a bulb 12 is formed so an to spread toward the opposing direction thereof, the spreading outside surfaces face the inner peripheries of both axial end parts of the bulb 12 so as not to face the central part of the bulb 12, that is, the inner periphery of an effective light emitting part. An electrode material radiated from the spreading outside of the cold cathode 13 sticks to the inner periphery of both axial end parts of the bulb 12 to cause blackening of a tube wall while being radiated on the effective light emitting inner periphery to be stuck so as to reduce tube wall blackening. Brightness lowering due to tube wall blackening of the effective light emitting part, therefore, can be prevented.

Abstract: PURPOSE:To obtain a compact and light-weight malfunction preventing device for control equipment mounted on an artificial satellite with low power consumption and at low cost by preparing an actuator selecting part and an actuator resetting signal generating part to reset the undesired drive signals. CONSTITUTION:An actuator selecting part 7 uses a mode flag signal and selects an undesired actuator in a control mode during the working.
