Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To allow a portable radio equipment without an ID code for network to communicate with a network radio equipment that makes network communication by using an ID code through the relay of a base station. SOLUTION: A network radio station 12 is made up of a network radio equipment 12a and a radio equipment 13 making communication with a portable radio equipment 11. The network radio station 12 receives a transmission signal of the portable radio equipment 11a by the radio equipment 13 and makes communication with the network radio station 12, when no ID code is found in the received signal. Or the network radio station 12 acts as a relay station between the portable radio equipments 11a, 11b and sets up a communication channel with a network radio equipment 15 of an opposite station, when detecting an ID code for network communication. When the communication channel is set, the network radio station 12 and a base station 14 act as a repeater to set a communication state between the portable radio equipment 11a and the network radio equipment 15.  Or when the network radio equipment 15 is busy with relaying, the portable radio equipment 11a makes communication with the portable radio equipment 11d that makes communication with the network radio equipment 15.

Filed: 1986-05-27
Abstract: PURPOSE:To decrease wow and transfer of vibration to chassis by damping a vibration generated in a stator coil with the flexibility of a planar body and the viscosity of a magnetic fluid enclosed in the planar body. CONSTITUTION:A stator coil 5 is secured to a flexible inclusion container 9 enclosing a magnetic fluid 8, which container 9 is secured to a chassis 2 so that the stator coil 5 is placed at a predetermined distance from a rotor magnet 1. When the rotor magnet 1 revolves, the magnetic fluid 8 in a back yoke 7 moves within the inclusion container 9 in keeping with a magnetic flux generated by the revolving rotor magnet l. Accordingly, no cogging is generated and a smooth revolution can be obtained. Also, a vibration generated when a brushless motor revolves, is damped by the flexibility of the inclusion container 9 and the viscosity of the magnetic fluid 8.

Filed: 1982-07-13
Abstract: PURPOSE:To speed up the circuit without increasing the occupied area of the circuit, by inserting a level shift circuit between an input terminal and at least one of a P or an N-channel MOS transistor(TR) gate. CONSTITUTION:A signal from an input terminal IN is applied to a gate of an NMOSQ2N constituting an inverter and also to a gate of a PMOSQ2P constituting similarly the inverter from a contact 21 via the level shift circuit comprising the QS2P and a resistor R2. The NMOSQ2N is turned off when an input is at an L level, taking a VT of the NMOS and the PMOS respectively as +1.0V and -1.0V and a shift amount of the level shift circuit as 3.2V, and a difference between the VT and a gate-source voltage VGS of the PMOSQ2P is -1V, and then, the difference between the VT and the VGS of the NMOSQ2P is 1V when the input is at an H level. Thus, the increase in the occupied area is prevented by making the gm of the PMOS and the NMOS equal to each other.

Abstract: PURPOSE: To provide a method for analyzing an interblock in which the lock holding units of execution units (units) blocked on lock can be retrieved, and tracking back in a chain can be attained until a cycle is detected while waiting. CONSTITUTION: Whether a present node is a unit or a lock is retrieved (S'4A), and when it is a lock, an arch connecting the node with the unit is drawn, and when it is neither a unit nor a lock, it goes out of the process (S'4B-D). When the node is a unit, whether or not it is waiting is judged (S'5), and when it is waiting and the waiting event is a lock, an arch connecting the node with the lock is drawn (S'6A-C), and when it is not a lock, a new node is added, and an arch for connecting it with the lock is drawn (S'6D-F). When the unit is not waiting, all processors are retrieved until an execution context is discovered (S'7-S'8B). When an execution pile is waiting for a lock, and an arch connecting the present node with the lock is not present, an arch is drawn (S'9, 10A, B), and when it is not waiting, and the other contexts are absent (S'10C), it goes out of the process.

Filed: 1983-07-07
Abstract: PURPOSE:To display a fault of a position detector and at the same time to deliver a signal which controls the position of a traveling object through a normal position detector, by providing plural position detectors which detect the same position of the traveling object which receives the position control. CONSTITUTION:A table 1 is turned counterclockwise and a 90 deg. detector 2 is turned on prior to a detector 2A. Thus a relay 21 works to close a contact 21a, and then a relay 23 works. Then a clutch brake 7 fixes the table 1 with a position control signal produced by a contact 23a of the relay 23. When the relay 23 is actuated, a time limiting relay 24 starts time counting. The output signal of a logical integration circuit consisting of contacts 21b and 22b of relays 21 and 22 is delivered consecutively in case another detector 2A has no actuation due to a fault or other factors for a period during which the relay 24 has no actuation. Therefore the relay 24 works after the time is up, and a fault detecting relay 26 works by a contact 24a. Accordingly an individual fault detecting relay 28 works. Then a fault is displayed by a display device 30.
