Title: Remote power supply disconnecting system
Inventor: YANO KAZUO
IPC: G06F1/00
Filed: 1983-07-19
Abstract: PURPOSE:To disconnect the power supply of subsystems connected to a cable collectively and quickly with just an instruction given from a host computer, by giving a power supply breaking indication to plural subsystems from the host computer via an optical transmission line. CONSTITUTION:The global addresses and instructions of plural loop interface devices 2 are produced from a host computer 1. These devices 2 connected to an optical fiber cable 8 recognize 9 a delivered break pattern and transfer it to processors 5 of subsystems 4 respectively. Thus the processor 5 gives a power supply breaking indication by software in response to a transferred breaking pattern after the end is confirmed for the job under execution. In response to the breaking indication, a breaking indicating device 11 applies a breaking signal to a power supply controller 6. Then the controller 6 gives an indication to a power supply device 7 to break the power supply. Thus the power supply is cut off to all subsystems 4 connected to the cable 8 with just a single operation.

Filed: 1988-05-31
Abstract: Selective compliance in up to six degrees of freedom in a magnetically levitated fine motion device, or robot wrist, with limited motion in X, Y, Z, ROLL, PITCH, YAW, is provided by controlled actuation currents applied to six electrodynamic forcer elements (5). The wrist has a stator support base (9) defining a dual periphery, carrying a number of stator magnet units (4). A shell flotor unit nests within the stator support base dual periphery, and carries forcer coils at locations corresponding to respective magnet units (4). The magnet unit (4) and related flotor coil (3) form a forcer element (5). There are a number of forcer elements (5). The vector sum of all the translational forces and rotational torques established at the forcer elements determines the X, Y, Z, ROLL, PITCH, YAW motion of the flotor. The flotor carries an end effector which may be a tool. Position and orientation of the flotor is monitored by light emitting diodes (7) and lateral effect colls. Coil currents are controlled as a composite of present position, desired final position, and desired compliance. As the fine motion device approaches its final position, the control unit changes forcer coil current patterns at various sets of forcer elements (5), to provide selected compliance in one or more degrees of freedom while approaching and finally while maintaining the desired position. Cooling is provided as needed; docking and locking provision is made to allow de-energizing the coils for cooling, motion of the base, or shutdown.

IPC: F01N3/28
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To surely lower catalyst poisoning by sulfur and to maintain high NOx purifying activity for a long time by introducing a reducing component into emission gas by means of a reduction constituent introducing means for establishing a rich atmosphere with an excessive amount of the reduction constituent, when a detection value of a sulfate detecting means sulfate concentration reaches a prescribed value. SOLUTION: Normally, lean-rich control is carried out, however, sulfation of a NOx storage element proceeds gradually. Then, a laser beam is periodically irradiated from a laser beam receiving device 4, to introduce Raman scattering light reflected by an alumina coat layer on a NOx storage reduction type catalyst 3 into a Raman spectrometer 5. The Raman spectrometer 5 calculates the ratio of sulfate in the whole Ba salt from the spectrum of the Raman scattering light and outputs a barium sulfate concentration to an air-fuel ratio controller 6.  The air-fuel ratio controller 6 compares the barium sulfate concentration with a prescribed value and carries out control for a prescribed time, so as to set the air-fuel ratio of the mixture to be rich, when the barium sulfate concentration is higher than the prescribed value, and by reducing the sulfate Ba recovers its initial NOx storage ability.

Title: Automatic focus adjusting device
Inventor: KAYANO YASUAKI
IPC: G03B13/36
Filed: 1989-05-29
Abstract: PURPOSE:To prevent the malfunction of automatic focus adjustment due to a random noise by providing a means which generates a control signal for moving a focus lens in a direction indicated by direction data when a specific number of the direction data indicating the same direction are counted continuously. CONSTITUTION:A far/close direction counter 13 which holds plural direction data outputs a signal indicating a rotating direction corresponding to the level of direction data when the direction data have the same level. Here, when the polarity of the integral voltage of a difference signal (A-B) is inverted owing to the mixing of a random noise, at least one of levels of the plural direction data held by the far/close direction counter 13 is affected by the random noise, so they are not equal in level and the far/close direction counter 13 does not output the signal k indicating the rotating direction of a motor. Consequently, a motor control circuit 12 stops the motor. Consequently, the malfunction due to the external random noise is precluded.
