Title: Position correction method for robot loaded on unmanned carrier
Inventor: SUZUKI HIROTOMO
IPC: B25J9/10
Filed: 1986-02-19
Abstract: PURPOSE:To correct a position at high accuracy without complicated image processing by generating a conversion equation based on the deviation amount of a mark position from that at the time of teaching and correcting the teaching point of a robot from the conversion equation. CONSTITUTION:An image input device 4 is shifted to right on a mark 8 and said position is taught. In that case, a horizontal and vertical coordinate system X-Y that sets the center of the bottom of a leg in the robot 2 to an origin for instant, and a direction in parallel with the horizontal scan line of the image input device 4 to an X axis is taken. Reading taught beforehand is played back at the position where the unmanned carrier 1 stops, and the mark 8 is read. The stop position of the unmanned carrier 1 is different from at teaching, and the X-Y coordinate system moves to a U-V coordinate system shown in figure. Accordingly, if coordinates (Xi, Yi) at the teaching point Pi taught by the X-Y coordinate system is converted into coordinates (Ui, Vi) in the U-V coordinate system, a work 6 can be correctly controlled.

Title: Guided air frame
Inventor: ISOMURA YUKIKO
IPC: B64C3/56
Filed: 1995-02-23
Abstract: PURPOSE: To obtain a foldable developing wing which allows an air frame to be contained in a launcher cylinder without restriction on the size of a main body of the air frame, by developing the wing by ant inertia force produced by conyrolling the roll of the fuselage. CONSTITUTION: After an air frame is launched, a foldable developing wing is developed by an inertia force produced by controlling the roll of the fuselage. The foldable developing wing is folded via a hinge 6. The fuselage is rolled once after launched and then rotated in the opposite direction, so that an upper part 2 of the foldable developing wing turns on the hinge 6 by the inertia force and locked. Although the roll control to develop the developing wing is carried out for a very short period of time after the launch, there is no effect on the flight of the fuselage. This method completely eliminates the need of a power source to develop the foldable developing wing. Therefore, as a power and a developing mechanism to develop the wing can be made needless or small- sized, the size of the air frame main body can be increased.  In addition, the flight performance is improved because the resistance is reduced.

Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To attain energy saving by making a projector usable as a light source of night-vision equipment as well as a car headlight and the like, and by preventing increase in cost and space, and by effectively utilizing optical energy of a lamp. SOLUTION: In a projector 10, a dichroic mirror 18 and a reflective mirror 20 are placed at the rear of a lamp 16. The dichroic mirror 18 reflects infrared rays IR and transmits visible rays B. The optical axis of the infrared rays IR reflected by the dichroic mirror 18 is set pointing upward with respect to the optical axis of the visible rays B reflected by the reflective mirror 20. Thus, because the single projector 10 can project the infrared rays IR as well as the visible rays B, the projector 10 is also usable as a light source of night-vision equipment without increase in cost and space and can effectively utilize optical energy of the lamp 16.

Title: Wood chip cement board
Inventor: MOROHARA JUNYA
IPC: C04B16/06
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To make it difficult to develop bursting phenomena even when a nail or the like is driven or possible to reduce the bursting phenomena to the minimum even when the bursting phenomena occur by a method wherein nettings, each of which consists of bundles made of synthetic resin monofilaments, are interposed in the whole region or in some part of a wood chip cement board. SOLUTION: A nail 3 is driven with a hammer or the like in a wood chip cement board 1, in which nettings 2 are interposed. A striking force with the hammer is transmitted to the tip direction of the nail 3, resulting in developing a force, which breaks down the wood chip cement board in a near conical shape. However, the interposing nettings 2 effectively absorb and disperse the destructive power, resulting in interrupting the proceeding of the destructive power beyond the netting 2. When the nail 3 passes through the netting 2, a destructive power develops anew. Thus, a destructive power is divided, resulting in making the lateral spread of the destructive power smaller.

Abstract: PROBLEM TO BE SOLVED: To reduce the software error induced by the alpha-particle in a dynamic logic circuit. SOLUTION: A logic block 500 has low speed logic units 512, 514 and high speed logic units 502, 504, 506. It has insulation circuits 532, 534, 536 disposed at outputs of the logic units 502, 504, 506.

Filed: 1992-02-24
Abstract: PURPOSE:To easily adjust the white balance with a high precision by applying a load to the collector on the side opposite to a signal distribution control output also in a current control part to reduce the output DC difference voltage due to the early effect. CONSTITUTION:A color signal and an inverted luminance signal are inputted to transistors TRs Q1 and Q2 respectively, and a DC voltage equal to the color signal and a pedestal DC voltage are inputted to TRs Q3 and Q4, respectively. On the signal side, the signal voltage is converted to a current by a resistance R1 and flows to the collector of a TR Q14; and on the DC side, the difference voltage is converted to a DC current by a resistance R2 and flows to the collector of the TR Q14. These both currents are shunted to a signal current control amplifier consisting of TRs Q5 and Q6 and a differential amplifier consisting of TRs Q7 and Q8 to obtain collector currents of these TRs, and output voltages are generated in resistances R4 and R12. At this time, a maximum current flows to TRs Q6 and Q7 in the case of a maximum signal current and flows to TRs Q5 and Q8 in the case of a minimum signal current and current values at this time are approximately equal to each other. Thus, the burden to correct the DC voltage difference is reduced to easily adjust the white balance.
