Title: Braking system for robot
Inventor: NISHIO AKIO
IPC: H02P3/16
Filed: 1988-07-08
Abstract: PURPOSE:To eliminate an impact and to effectively brake a robot by braking a driving motor of a robot joint by generative braking when its rotating speed is high and adding a mechanical brake thereto when it is lower than a predetermined speed. CONSTITUTION:DC motors 1 are so disposed at the joints of a multi-joint arm as to turn, rotate the joints, and driven by a motor driver 2. The driver 2 has 4 transistors(Tr), which are alternately conducted by a base driving circuit 3 to supply a current to the motors 1. A mechanical brake such as an electromagnetic brake is coupled to the motor 1, and a generative brake resistor 6 for absorbing generative power of the motor 1 is connected to a closed circuit formed by closing the contact 5a of a relay 5. A trouble detector 7, a power source interruption detector 8 are provided, and the logic sum signal S3 of the detection signals S1-S2 is supplied to the circuit 3 and a combination circuit 10. Thus, after a generative braking, when it becomes a low speed, the circuit 10 operates a mechanical brake 4.

Title: Gas laser equipment
Inventor: IEHISA NOBUAKI
IPC: B23K26/00
Filed: 1987-07-07
Abstract: PURPOSE:To avoid the degradation and instability of a laser output caused by mixing up with the air by a method wherein a steam detection means and a stop and control means are provided and a gas leakage is automatically detected and the operation of the gas laser equipment is stopped. CONSTITUTION:Gas is supplied to a discharge tube 1 from a laser gas feeder 5 through a supply valve 6. The steam pressure of 0.1-0.2Torr in the tube 1 is detected by a sensor 7 and the leakage of the air can be detected easily. The deteriorated gas is exhausted by an exhauster 9 through an exhaust valve 8. A numerical controller 10 detects a gas leakage by transmitting the output of the steam pressure sensor 7 through an A/D converter 11 and a steam detection circuit 12 and a stop and control means 13 stops the whole equipment when the leakage is detected and displays 'gas leakage' on a display 14. With this constitution, the gas laser equipment is never operated while the air is leaking into the oscillator such as the discharge tube so that the degradation and instability of the laser output caused by mixing up with the air can be avoided.

Title: Dredging method for earth and sand built up in pipeline
Inventor: YOKOSHIMA YASUHIRO
IPC: B08B9/02
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To clean the inside of a pipeline by dredging even earth and sand built up in a large-sized or zigzag pipeline definitely and efficiently. SOLUTION: A high air-tight tubular envelop 5, which is connected to a compressor 7 (a compressed air supply source), is inserted into a pipeline 1. Then, a compressed air is supplied to the tubular envelope 5, thereby expanding the tubular envelop 5. The inside of the pipeline 1 is blocked with the expanded envelop 5 so that water may be accumulated in the upstream area of the tubular envelop 5. When a specified amount of water is accumulated, the compressed air is vented gradually from the tubular envelop 5 so that the accumulated water may flow in a clearance between the tubular envelop 5 and the pipeline 1, thereby carrying downstream the water with earth and sand 3 built up the bottom of the pipeline 1. The earth and sand 3 is dammed up with a sandbag (weir) 13 provided on the downstream side and pumped up to the ground together with the water by means of a sand pump 12.  Since the tubular envelop is insertible easily into a large-sized or zigzag pipeline due to this construction and functions as one type of a valve, it is possible to carry downstream even the earth and sand 3 built up in the pipeline and dredge the earth and sand 3 definitely.

IPC: B62D113/00
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce manipulative burden on a driver and incompatibility sense giving thereto by automatically recovering the vehicle attitude disturbance of a vehicle itself caused by collision avoiding control when avoiding the collision of the vehicle itself and a car running on the opposite lane by automatic steering. SOLUTION: If there is possibility that a vehicle itself is collided with a car running on the opposite lane, sinusoidal wave-like transverse moving current I1 is supplied to the actuator of an electric power steering device and the vehicle itself is transversely moved so as to avoid the collision between the car running on the opposite lane. At the same time when transverse movement is started, a yaw rate is integrated so as to detect the yaw angle of the vehicle itself, and yaw angle correcting current I2 is superimposed on the transverse moving current I1 and supplied to the actuator so that the yaw angle is converged to 0 from the final stage of the transverse movement so as to recover the vehicle position to its original condition.  Therefore, after avoiding the collision with the car running on the opposite lane, the vehicle attitude disturbance of the vehicle itself can be automatically recovered, and manipulative burden on a driver and incompatibility sense giving thereto can be reduced.

Title: Wavelength-variable surface-emission laser device and its manufacture
Inventor: UCHIYAMA SEIJI
IPC: H01S5/06
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To control oscillation wavelength by a mirror and an electrode for wavelength control facing each other a predetermined distance away from the laser main body. SOLUTION: A mirror 4 formed on substrates 2 (2a and 2b) is junction- integrated with a surface-emission laser main body 1. The mirror 4 is winterposed to the laser main body 1, with a predetermined interval, via spacing having an opening 3. When a predetermined voltage is applied between a p electrode 19 and an n electrode 18, quantum-well active layer 19 is excited, and it reconates between a mirror layer 12 and the mirror 4, to output laser light. At this time, when a voltage is applied between wavelength-control electrodes 5 (5a and 5b), an electrostatic force acts on the substrate 2, to vary a spacing gap length d of the opening 3, and the distance between the mirror 4 and the surface-emission laser main body 1 changes. As a result, the length of resonance path of the surface-emission laser main body 1 changes, and the oscillation wavelength changes.  Thus, the oscillation wavelength can be variably controlled in a wide range, in a simple and stable manner.
