摘要： An electromagnetic actuator has a stator core, an armature and a coil. The stator core is formed as a seamless cylindrical tube having a thin wall as a magnetic restrictor. The thin wall has a thickness sufficient to maintain a mechanical strength of the stator core. A permanent magnet is located on an outside of the thin wall to generate a magnetic flux passing through the thin wall in the same direction as a magnetic flux generated by the coil. The thin wall is magnetically saturated with the magnetic flux generated by the permanent magnet. When the coil is energized, a magnetic flux generated by the coil gets around the saturated thin wall and passes through the armature.

摘要： A compact and high-accuracy angular position measuring device is provided which has magnets installed in a rotor core and a magnetic sensor installed in a stator core. The magnetic sensor produces an output indicative of an angular position of the rotor core as a function of a change in density of magnetic flux produced by the magnets. The magnets are so arranged in the rotor core that the same poles are opposed magnetically to produce a repellent force in magnetic fields of the magnets, thereby causing the magnetic flux to go to the magnetic sensor through the rotor core. This eliminates the need for an air gap between the stator core and the poles of the magnets which is formed in a conventional device, thus allowing the device to be reduced in size and an error in output of the device to be decreased.

摘要： A signal processing circuit which enables an error bit to be set simply without causing an increase in the size of the circuit even if the packet size is changed and which enables realization of stable operation without the system stopping even if the value of the time stamp is impossible. A pre-reception processing circuit decides if a received packet is normally continuous or discontinuous from data in the DBC region of the CIP header. When deciding it is discontinuous, it sets an error bit ERM allocated to one bit of the upper significant 7 bits of the source packet header to “1”, and writes this in an FIFO. A post-reception processing circuit, when reading from the FIFO, outputs the data stored in the FIFO to the application side when the error bit ERM is “0” and resets the error bit and outputs a dummy error packet when the error bit EMR is “1”.

摘要： A stroke sensor has two magnets, which are magnetized in a cross-section direction and are displaced in a longitudinal direction, and two magnetism sensitive sections arranged parallel to the longitudinal direction. The magnets have circular-arc-shaped swelling end edges respectively and are magnetized such that the swelling end edges have opposite polarities. Thus, a distribution of a magnetic flux density on an arrangement axis substantially coincides with a sine curve. The magnetic flux having such the distribution is displaced in the longitudinal direction together with the magnets. The magnetism sensitive sections are arranged on the arrangement axis to be distant from each other by a distance of one fourth of a cycle of the sine curve. Thus, the stroke sensor that is not affected by temperature and that has high sensing accuracy can be provided.

摘要： An LSI which makes scan testing possible without compromising security is provided. Flip-flops that constitute a scan chain are reset when scan testing is initiated or terminated by the edges of a mode signal for switching between normal operations and scan testing. In addition, during scan testing, internal memory means is made inaccessible. Further, a dummy flip-flop that operates only during scan testing is connected to the scan chain, and shifting out by the scan chain during normal operations is made impossible.

摘要： This invention is intended to realize with ease flow control and quantization error reduction in a data transfer operation executed via the IEEE 1394 serial bus. A FIFO once holds data supplied from a decoder and outputs the data in a predetermined send timing relation. At this moment, a counter counts the number of packets to sent from the FIFO to an IEEE 1394 bus. In order to increasing data transfer quantity in accordance with a send command issued by a register, a data packet is sent at transfer of an empty packet. In order to decrease data transfer quantity, an empty packet is sent in a timed relation in which a data packet is sent. A data quantity monitor requests the decoder for supplying data or stopping thereof via a data input controller so as to prevent the FIFO from overflowing or being emptied in accordance with flow control.
