  • Patent number: 6377428
    Abstract: A switching device includes a commanding device (813, Q51) which commands a driving of a load, a driving device (111) which outputs a drive signal in response to a drive command signal from the commanding device (813, Q51) and a first switching device (QA) inserted in a power supply circuit connecting a power supply (101) and the load (102). The first switching device (QA) is adapted to conduct in response to the drive signal and close the power supply circuit. A reference resistor (Rr1, Rr2) generates a reference voltage by receiving a current from the power supply, and a second switching device (QB, QC) is inserted in a shunt circuit connecting the power supply and the reference resistor. The second switching device (QB, QC) is adapted to conduct in response to the drive signal and close the shunt circuit. An abnormality determining device (CMP1, CMP2) determines an abnormality by comparing an output voltage from the first switching device (QA) and the reference voltage.

  • Publication number: 20020043948
    Abstract: A simple and cheap opening and closing motion control device is provided for avoiding pinching of an object X by a window glass 33 with high accuracy. The device includes a flexible weather strip 35 arranged along a contact portion of a window frame 31, the contact portion being touched by the window glass 33 when it is closed up perfectly, a liner electrostatic-capacity detecting sensor 13 embedded in the weather strip 35, for always detecting an electrostatic capacity in the circumference of the sensor 13, a control micro-computer 23 for judging whether or not the object X is pinched by the closing motion of the window glass 33, on the basis of the detection of the sensor 13, and a motor drive circuit 25 for allowing a motor 27 to either stop or open the window glass 33 when the micro-computer 23 judges that the object X is on the point of being pinched.

  • Publication number: 20010017587
    Abstract: A pressure-sensitive sensor is provided with a tube member having a hollow portion defined by an inner wall and made of flexible material, a first belt-like electrode disposed on an upper side of the tube member in the tube member and a second belt-like electrode disposed on a lower side of the hollow portion in the tube member so as to oppose the first belt-like electrode. When the pressure-sensitive sensor is pressed, the first belt-like electrode and the second belt-like electrode are capable of contacting each other so as to ensure conductivity. Further the pressure-sensitive sensor has a contact adjusting portion provided on an inner wall of the tube member and for adjusting a contact between the first belt-like electrode and the second belt-like electrode. Additionally, a connector capable of being combined with such a pressure-sensitive sensor is also disclosed.

  • Patent number: 6151306
    Abstract: A vehicle communication multiplex system comprises: a bus; and a plurality of nodes connected to the bus, wherein transmission right circulates to the nodes in a predetermined order and send a predetermined number of data to the bus from the node which gets the transmission right. Each of the nodes includes, a block division section for dividing the data into blocks to prepare data blocks, a change-block-determination section for determining whether or not each of the data blocks prepared by the block division section changes as an event occurs, and a data transmission section, if the change-block-determination section determines that a data block changes, for extracting the data block from the block division section and sending the extracted data block to the bus.

  • Patent number: 5418721
    Abstract: A data transmission control device is provided for each of a plurality of units for controlling transmission of supervisory control data. Each control device includes a data error checking unit which causes a data reception unit to transmit a response signal when an error has been detected in the data by the data error checking unit. If a response signal detecting section in the transmitting unit detects a response signal, a data transmission unit resends the common data.

  • Patent number: 5001928
    Abstract: A level detecting resistor (Rd) is inserted into a liquid (5) and has a length immersed in the liquid. The level detecting resistor (Rd) is supplied a constant current (Id) from a constant current source (1). The voltage drop (Vd) developed across the level detecting resistor (Rd) is supplied to a non-inverting input terminal of a differential input amplifier (OP1, R1-R4). The output (Vo) of the differential input amplifier is then divided by a series-circuit of a temperature compensating resistor (Rc) and a resistor (R5). The divided voltage (Va) across the resistor (R5) is fed back via a voltage follower (OP2) to the non-inverting input terminal of the differential input amplifier.
