A semiconductor device includes a substrate, a well region formed in the substrate, a field effect transistor formed in the well region, and a diffused region, formed across the well region and the substrate for applying back gate potential to the well region, and forming a PN junction together with its periphery. The field effect transistor and the PN junction are connected between terminals for absorbing excess current so that an internal circuit connected to the terminals is protected.

A path network and a path network operation method capable of dealing with an abrupt traffic variation by realizing fast path bandwidth increase are disclosed. A path network is operated by transmitting path signals from a transmitting node to a receiving node through the working paths and the protection paths, and converting a protection path into a working path temporarily in order to increase a bandwidth of the working paths when a bandwidth increase request occurs in the path network. The transmitting node and the receiving node can convert a protection path into a working path by using the automatic path conversion information contained in the path overhead attached to the path signals.

An arbitrary signal is converted to IP packets, which are routed by an IP packet routing part to Optical path signal conversion parts. Optical path signals from the Optical path signal conversion parts are provided directly to an optical path route switching part of an IP packet transmission equipment. By the optical path route switching part, optical path signals, obtained by wavelength-demultiplexing of OTM signals from optical backbone transmission lines by OTM/optical path signal conversion parts, and optical path signals from the Optical path signal conversion parts are cross-connected to output routes according to their destinations.

The battery pack has batteries, a printed circuit board with battery protection circuit components mounted on it, and a circuit breaker contained in a case. The circuit breaker switches off if excessive current flows in the batteries, or if battery temperature exceeds a specified temperature. The circuit breaker has a plurality of solder terminals attached to its casing, and one or a plurality of the solder terminals are attached to the printed circuit board by solder re-flow. The printed circuit board is connected to the batteries via leads and is disposed in a fixed position inside the case. The circuit breaker is mounted in a fixed position inside the case via the printed circuit board.

A semiconductor light emitting device having multi-layer structure of group-3 nitride-based semiconductors is disclosed. The light emitting device has lower density of threading dislocation extending from a boundary of a crystal substrate through the multi-layer structure, thereby obtaining good luminescence characteristics. The nitride semiconductor light emitting device has the multi-layer structure. The multi-layer structure comprises a first crystal layer containing substantially pyramidal crystal grains, each of grains has a crystal face non-parallel to a surface of the substrate, and the pyramidal crystal grains are distributed at random like islands. The structure further comprises a second crystal layer formed on the first crystal layer with a compound having a different lattice constant from that of the first crystal layer. The second crystal layer smoothes a surface of the first crystal layer parallel to the surface of the substrate.
摘要:
A robot controller which controls a process controlled variable of an operational tool mounted on a robot in synchronism with the robot motion. The position of each axis of the robot is detected by a sensor such as a position detector. In a calculating section, motion variables such as position Pn, velocity vn and acceleration &agr;n of a tool center point (TCP) are detected from the respective positions of the robot axes. An ideal output (target value) of a sensor for detecting a controlled variable to be controlled in accordance with the motion state is determined in a calculating section. A sensor output is subtracted from the target value to determine a deviation. The deviation is multiplied by a proportional gain K to determine a manipulated variable. By using this manipulated variable, the process of an arc welding machine, sealing machine, or laser beam machine in which a tool is mounted on a distal end of a robot wrist is controlled. The target value is determined in accordance with the change of motion state of the robot, and feedback control is carried out so as to follow the target value so that uniform operation is achieved.

The invention is a robot teaching pendant containing a display device with graphic display capabilities. Display data is displayed on the graphic display and includes the movement of a robot and taught points. This display data is generated by a display data generation unit based on robot programs stored in data storage unit by buffering the data from a robot controller. This display data may also include representative images of the robot tool along with its coordinates in a tool coordinate system and the taught points in a user or world coordinate system. Thus, the action of the robot can be visually recognized with ease, and the robot can be taught easily and accurately.
