Abstract: PURPOSE:To stabilize the quality of a water-glass fiber by introducing CO2 gas into a spinning atmosphere having a prescribed temperature and spinning water-glass in the CO2 atmosphere having a prescribed CO2 gas concentration. CONSTITUTION:A water-glass spinning dope melted by heating with a 1st heater 8 is pressed in a cylinder 6 and extruded through a spinning nozzle 7 having a prescribed nozzle diameter into an acrylic resin pipe to effect the continuous spinning of the water-glass. At the same time, CO2 gas is continuously introduced through a gas-introducing port 14 of a drum chamber 4 to keep a nozzle part 2, a cylindrical furnace 3 and the drum chamber 4 to a CO2 atmosphere having a CO2 concentration of 100-8,000ppm. The spun water-glass fiber is brought into contact with CO2 gas in the course of passing through the CO2 gas atmosphere of 100-130 deg.C) to instantaneously form crystals of Na2CO3 and Na2CO3.H2O on the surface of the fiber. The fiber is dried by heating with a 2nd heater 9 of the cylindrical furnace 3 and a 3rd heater 12 placed under the drum chamber 4 and wound on a winding drum 11 to obtain a water-glass fiber having stable quality and free from blister or bubble.

Filed: 1990-08-24
Abstract: PURPOSE:To reduce paper consumption and to prevent personal information from being intercepted by other party by printing out only information required to be left on paper through an instruction of a user and deleting the other information from a storage means. CONSTITUTION:Received information is stored in a storage device 10 by a control section 8. When the user requires information received by the user, the information stored in the storage device 10 is displayed on a display screen 5 to urge the user as to judge whether the information is required or not. When it is not required to print out the information on paper, the control section 8 aborts or deletes the information from the storage device 10. Thus, the amount of paper used is remarkable reduced and since the information undesired to be intercepted by other party such as personal information is not left on paper, the leakage to other party is prevented.

Filed: 1983-11-28
Abstract: PURPOSE:To plan miniaturization, light weight, improvement in reliability and low cost of a device by permitting turn-on and turn-off by use of an optical signal. CONSTITUTION:When an optical signal hnu is projected on a base-emitter junction of an NPNTR73 of a subsidiary GTO thyristor unit 61, a pair of an electron and a hole is generated in a depletion region, and the hole and the electron are separated in the base side and the N<+> type emitter side respectively. When a potential difference due to electrons and holes is substantially equal to a potential difference due to diffusion, a current starts to flow through the NPNTR73 and it becomes a base current of the NPNTR72. By this, the subsidiary GTO thyristor unit 61 is turned on and a main GTO thyristor unit 60 is turned on by a cathode current of the thyristor unit 61 via a resistor R2. Consequently, a large current flows between an anode electrode A and a cathode electrode K. To turn the thyristor off, an optical signal Hnu is projected on a photodiode unit 63.

IPC: C23C2/16
Filed: 1989-08-30
Abstract: PURPOSE:To improve the quality of a product by causing a high pressure gas to flow from a nozzle just after executing molten metal plating to a steel strip, inducing gas along the steel strip, sucking and approaching the steel strip to the nozzle with magnetic force. CONSTITUTION:In the continuous molten plating, uniform plating coating is executed.

Title: Control method for robot attitude
Inventor: KATSUKURA MIKINE
IPC: B25J9/16
Filed: 1987-09-09
Abstract: PURPOSE:To secure the optimum attitude of a robot when an obstacle is evaded by defining the coefficient that decides the value of a 2nd moment as a function and reducing this function value as the robot moves further away from a target position. CONSTITUTION:A moment M1 is obtained by applying the image transformation to the outputs of external sensors 21 and 22 of a robot 1 into an (n+1)- dimensional virtual space corresponding to an N-dimensional work space. A moment M2 is produced from the product of a certain coefficient and the deviation between the target attitude phir and the present attitude phi of the robot 1 set at the arrived target position. Then a moment M3 is obtained from the present rotational angle speed. The attitude of the robot 1 is controlled by said moments M1-M3. Here a function is used to the coefficient that decides the value of the moment M2 and this function value is reduced as the robot 1 moves further away from the target position. Thus the robot 1 is controlled to an attitude optimum to evade obstacles at a place remote from the target position. The value of the M2 is increased when the robot 1 moves close to the target. As a result, the robot 1 is controlled so as to be turned accurately to a target angle at a target position.

Title: Converting method for vision coordinates into robot coordinates
Inventor: SATO SATOSHI
IPC: G05B19/19
Filed: 1987-09-09
Abstract: PURPOSE:To easily convert the vision coordinates into the robot coordinates by using a jig that can perform input of the robot coordinate point to fetch this point into a vision viewfield. CONSTITUTION:A point A equivalent to an original point and a point B slightly distant from the point A are plotted on a screen 19 which is parallel to an XY plane of the robot coordinates by means of a marker of an offset jig 18 put into a robot hand 6. Then the distance of the vision coordinates is obtained from the vision coordinate value that is recognized out of the picture of a TV camera 1 which photographs both points A and B at one time. Thus a conversion coefficient between the vision and robot coordinates is obtained from the difference between the vision coordinate distance and the robot coordinates set at plotting. Furthermore the coordinate value of an optional point on the vision coordinates is converted into the tentative vision coordinate value based on the coordinate values of both points A and B and then into the robot coordinates with addition of the difference between the tentative vision coordinates and the robot coordinates. In such a way, the vision coordinates value is simply converted into the robot coordinate value.

Filed: 1991-09-04
Abstract: PURPOSE:To easily form a stereoscopic image for two-eye stereoscopic vision by color-separating and reading an object image and its shadow, separating the object image from the shadow and recording them in specified colors. CONSTITUTION:When three-dimensional object OD is illuminated from an oblique direction, a hatched part expresses a shadow part.

Next, the object image is formed and recorded in the specified color and the shadow part is formed and recorded in another specified color by an optical scanning electrophotographic system. In such a case, the density of the recorded and formed images of two colors is made lower than the density of the essential object image and the shadow. Then, an original image IM on an original 0 is read, and a recorded and formed red image IR and a recorded and formed blue image IB, which is deviated by a specified distance from the image IR, are formed and recorded from the image IM by the optical scanning electrophotographic system. Therefore, the stereoscopic images are observed by two-eye stereoscopic vision.
