Title: Device for detecting position of bogie
Inventor: KANEKO TSUTOMU
IPC: G01B21/00
Filed: 1994-02-24
Abstract: PURPOSE:To detect the position of a bogie running with the use of a simple structure by storing data of a distance between two reference positions set in a moving area, in a control device, by stretching a wire rope between the reference positions so as to detect the length of the rope by means of a distance sensor, and by calculating positional coordinates from distance data and positional data. CONSTITUTION:Data of a distance L between two reference positions A, B set in a moving area C for a bogie 5 are stored in a control device 7, and an instruction for starting the movement is delivered. Then, angle sensors 21, 22 detect crossing angles (theta, delta) between a reference line J and lines M, N in directions in which a rope 16 is extended. Meanwhile, a distance sensor 20 detects a length of the rope 16 so as to obtain a distance between the reference point A and the crossing point C. Further, a turn sensor 23 detects a turn angle 6. From thus obtained data, the positional coordinates of the crossing point C and the a base point of the bogie 5 on the X-Y orthogonal coordinate system having the position A as the original point and the Y-axis which passes through the positions A, B are calculated. Thereby the position detecting device can be used even in circumstances in which vibrations are frequent, and is less in failure while it can be easily repaired in a job cite.

Title: Floating-point adder circuit
Inventor: NAKAMURA SADAO
IPC: G06F7/485
Filed: 1984-02-17
Abstract: PURPOSE:To obtain a floating point adder circuit which works at a high speed to attain the denormalization, by realizing the parallel actuations of circuit component elements and therefore decreasing the number of signal transmission lines between an input and an output. CONSTITUTION:A heat zero bit counter 45 counts the number of zeros continuous from the highest digit of an input mantissa and delivers the count result in parallel to the actuation of a rounding circuit 44. The exponent part replacement circuits 46 and 47 perform subtractions from an input exponent by means of the number of head zero bits, i.e., the output of the counter 45 and the value less than said zero bit number by 1 and delivers two types of replacement exponent value. In this subtraction mode, the correction of the exponent part due to an overflow phenomenon of a mantissa part produced at a preceding stage is also carried out at a time. A selector 48 usually selects the output of the counter 45 and then selects an input exponent 42 owing to the denormalization in case an underflow phenomenon occurs with one of both subtractors 46 and 47 that delivers smaller replacement exponent value. Then a selector 49 selects value 0 as the final output exponent.

Title: Orthogonal biaxial control type monopulse tracking circuit
Inventor: SUDA TAMOTSU
IPC: G01S3/42
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To reduce the size, weight, and cost of an orthogonal biaxial monopulse tracking antenna by constructing the antenna in a planar structure and reducing the number of members by installing two feeding points having opposite phases to each element antenna. SOLUTION: Four element antennas 1-1 to 1-4 are arranged in two lines and two rows and two feeding points of opposite phases are installed to each antenna 1-1 to 1-4. A sum signal is generated by adding the receiving power of the feeding points (for example, 2-7 and 2-8) having the same phase of the antennas (for example, 1-3 and 1-4) belonging to the same line or row to each other. In addition, a difference signal is generated by adding the power of the receiving power of the feeding points (for example, 2-5 and 2-2) having opposite phases of the antenna (for example, 1-1 and 1-2) belonging to the same line or row to each other. Therefore, an orthogonal biaxial monopulse tracking antenna can be reduced in size and weight by constructing the antenna in a planar structure, because no three-dimensional wiring is required and a simple microstrip line can be used for feeding.

Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To make an apparatus small in size and to dissipate quickly and surely the heat other than that required dry ink, by a method wherein the heat generated in a printer case body is dissipated by an intake fan, while a heat dissipating plate which guides an air flow in the direction of delivery of a printing medium is provided. SOLUTION: A printing medium M being held passes a nozzle head 200 for colors as a drum 10 rotates and characters and images are printed thereon. Drying of ink applied is facilitated by the heat generated by a heat generating means 31. An intake fan 32 urges the air from an inlet 5 and sends it in the direction of the left. Taking the heat from a heat dissipating plate 33 (fin 34), a flow of this air runs from a medium peeling means 140 toward the delivering- carrying means 160 side, guided by the fin 34. The air flow (hot air flow) is guided in the direction of delivering and carrying the printing medium, by the fin 34. The heat dissipating function of the heat dissipating plate 33 with the fin 34 is facilitated further, since the heat is taken by the air flow.
