IPC: H02G9/06
Filed: 1989-12-04
Abstract: PURPOSE:To manufacture a duct in an ultra-long span easily by heating a sheet while being led out of the roll of a rigid plastic sheet in width equal to the circumferential length or a small-diameter duct, cylindrically forming the sheet and inserting the cylindrically shaped duct into a main duct after cooling. CONSTITUTION:A casing 14 in which the roll 6a of a thermoplastic rigid plastic sheet 6 having width equal to the circumferential length of a small-diameter duct and equal to the length of a main duct 3 is housed is installed near a shaft 1. The sheet 6 is guided by rolls 18a, 18b, and passed through a member 19 for deformation machining while being heated by steam in a tilted duct 16 and a horizontal duct 15. The sheet 6 is pushed so as to wrap in a cable 4, and deformed in a tubular shape 6b. When the sheet 6 is projected from the horizontal duct 15, it is cooled by cooling water 17 and solidified, and a tow rope 22 is mounted at a nose thereof through a connecting fitting 21. The rope 22 is wound on the winch of another shaft not shown. Accordingly, the small-diameter duct in an ultra-long span of several hundred m is manufactured easily at low cost while being laid.

IPC: F27B1/00
Filed: 1989-12-05
Abstract: PURPOSE:To burn a material to be burned with a desired temperature profile, increase the space productivity of a furnace and reduce energy loss by a method wherein the material to be burned in a burning box is burned while passing through respective burning zones, controlled independently with a predetermined set temperature, in the process of descending sequentially through the inside of a core tube, penetrating up-and-down through a vertical furnace body. CONSTITUTION:A box 16 is descended sequentially through the inside of a core tube 14 at every times when a material to be burned, which is received into the box 16, is taken out of an extended tube 20 at the side of the lower end 14b of the core tube 14 by a chucking device 17. Under this process, the material to be burned in the box 16 passes through respective calcining zones 24 and is burned. The temperature of respective burning zones 24 is controlled independently by a predetermined set temperature. Accordingly, the material to be burned in the box 16 is heated to the controlled temperature of the zones 24 under the process of passing through respective burning zones 24 uniformly with a desired temperature profile. A furnace body 12 is vertical type and compact whereby the heat capacity of the same is small while the box 16 is also small size and the heat capacity thereof is small whereby energy loss may be reduced.

Title: Voltage controlled oscillation circuit
Inventor: ABE AKIRA
IPC: H03L7/093
Filed: 1989-12-05
Abstract: PURPOSE:To enlarge a corresponding data transfer rate width by separating an offset voltage generation circuit and a circuit for corresponding to a different data transfer rate, and reducing the output voltage change extent of the offset voltage generation circuit. CONSTITUTION:The output 14 of an oscillation circuit 13 is compared with a reference frequency input 15 in a phase comparison circuit 16, and the output 17 is inputted to a filter circuit 18. The output 19 of the circuit 18 is inputted to a transistor 7 and a phase comparison loop is formed. When the phase comparison loop comes to a balanced state, the oscillation circuit 13 oscillates at the same frequency as the reference frequency 15, and an offset voltage 9 operates so that it makes the center frequency of the oscillation circuit 20 equal to the reference frequency. Here, correspondence to various data rates is attained by fixing a resistor 8, changing the input 15 to the desired data rate and changing the resistance value of a current setting resistor 4. Consequently, the data transfer rate width can be enlarged without changing the output voltage of a filter circuit 18 largely.

Abstract: PURPOSE:To simplify assembly work by executing the deflection and convergent of a light source laser beam which is reflected by a beam splitter, detecting the position of the laser beam in a radius direction and integrating a position detecting mechanism. CONSTITUTION:A laser light emitted from a laser diode 11 goes through a coupling lens 12 and passes through a polarizing beam splitter (PBS) 13, lambda/4 board and objective lens 15. Then, the image formation of the laser light is executed in the recording track of an optical disk 16. A reflected light (signal light) goes reversely and is reflected by the PBS 13. Then, the light passes through the lens and the half of a light flux is reflected by a divided mirror 18 and incident to a two-divided photo-detecting element 19 for track servo. The remained light flux is incident on a two-divided photo-detecting element 20 for focus servo. On the other hand, the light source laser beam reflected by the PBS 13 is passed through a window 2a and a detected light LC is incident on a position detecting element 5. When an optical pickup device 2 moves from an inside limit position EC in a disk 16 to an outside limit position ED, the beam LC moves from SPa to SPb and the position in the radius direction is detected from the output of the element 5.

IPC: G08G1/16
Filed: 1990-11-20
Abstract: PURPOSE:To effectively detect an intermittent whit line (broken line) that identifies a traffic lane by changing the area segmented from an image in accordance with the vehicle speed. CONSTITUTION:The signal received from a TV camera 20 is written into a frame memory 24 by an A/D converter 22, and an area used for detection of a white line is decided and sent to a DSP 40. The DSP 40 detects the edge of a picture element, recognizes the position of the white line based on the result of detection, and changes the position of a window based on the result of recognition. The window position is shifted toward the front of a road by V t for each processing loop as long as the window position is fixed together with a vehicle speed set at V and the white line detecting cycle set at  t respectively. A changing point is recognized when the white line is omitted or the detection of the white line is impossible. Thus the distance shifted is operated as prescribed. In such a constitution, the white line can be detected in any state and even a broken white line can also be detected.
