  • Patent number: 5365344
    Abstract: A plurality of node apparatuses are connected by an optical transmission line. Each of the node apparatuses is assigned with a wavelength as an address different from the others. Therefore, when a first node apparatus transmits data to a second node apparatus, the data is of a wavelength corresponding to the address of the second node apparatus. The data transmission is carried out in a time slot defined by a frame pulse. The data of the corresponding wavelength is only received in the second node apparatus, and data of other wavelengths are passed through the second node apparatus. Consequently, media-access control is easily carried out independently in each node apparatus in an optical network system by using wavelength division multiplexing.

  • Patent number: 5289302
    Abstract: A supervisory node (2) and non-supervisory nodes (3 through 9) are connected in a loop by an optical transmission path (1). Over the loop (1) are transferred optical signals having wavelengths of .lambda.1 through .lambda. n. An access right control packet 10 is transferred in the loop at the optical wavelength of .lambda.1. A node performing data transmission by line exchange writes its own node address (SA), the destination address (DA) and transmit reservation in the header of the access right control packet 10, and sends the packet out on the optical transmission path. The supervisory node 2 having received this access right control packet writes the wavelength to be used (.lambda.i) into the used wavelength field (UWL), and notifies the transmit and receive nodes of the choice of the wavelength. The transmit node sends data to the receive node by line exchange at the designated wavelength .lambda.i.

  • Patent number: 4901536
    Abstract: A control system for controlling an actuator and a display unit of an air-conditioner, and a method of adjusting the control system. An operational amplifier executes calculation on the basis of analogue data from a plurality of temperature-data input terminals. An output from the operational amplifier is sent to a microcomputer through an A/D converter. In a normal control mode, the microcomputer controls the display unit and the actuator of the air conditioner. The microcomputer executes also an adjusting mode in which the microcomputer controls the display unit to display an outut voltage from the operational amplifier. The microcomputer selects one of the modes to be executed in response to a mode signal from a mode-signal generator. A reference voltage is inputted to the operational amplifier from a reference-voltage generating circuit. The reference voltage is adjusted such that the output voltage from the operational amplifier displayed on the display unit is brought to a predetermined standard level.

  • Patent number: 4408660
    Abstract: A sensor (27) is provided to sense the humidity at the inner surface of a window of a vehicle interior. When the sensed surface humidity is above a certain value, the possibility of the window being fogged arises and the proportion of outside air to recirculated air is increased to 100% to reduce the interior humidity. When the surface humidity is above a higher value, the interior air control system (5) is operated to reduce the interior humidity by increasing the amount of inlet air, the inlet air temperature, etc.
