Abstract: A connecting structure consists of an electrical connection box and a fusible link connector to be inserted into the connection box. The fusible link connector includes an insulating housing, a fusible link and a pair of nuts to be inserted into the housing and fitted at respective predetermined utmost positions therein. The electrical connection box is provided with a concave connector receiving portion into which the fusible link connector is to be inserted and which includes a pair of nut-abutting parts. In process of inserting the connector into the electrical connection box, if the nut-abutting parts come into contact with the nuts in the utmost positions, the parts serve to define the positional limit in inserting the insulating housing to a predetermined regular position. On the contrary, if the nut-abutting parts come into contact with the nuts inserted incompletely, the parts serve to prevent the insulating housing from being inserted into the predetermined regular position.

Abstract: A plurality of data carriers are prepared and possessed by, for example, persons who enter a building. The data carrier spread spectrum modulates a carrier signal of a predetermined frequency by an assigned Gold series corresponding to an ID code and transmits the modulated signal. Leaky cables each having a predetermined length are two-dimensionally distributed and arranged in the building. A frequency converter is connected to one end of each of the leaky cables and frequency converts the spread spectrum signal from the data carrier which has propagated the leaky cable into a frequency unique to the cable and sends the converted frequency signal to a central receiving unit through a transmission cable. The receiving unit individually demodulates the signal series from the reception signals and sequentially executes correlation calculations between the signal series and the Gold series assigned to the data carriers.

Abstract: Bidirectional transmission of write and read data is effected between a reader/writer unit and a memory module in a contactless manner using electromagnetic induction coupling. A single magnetic induction coupling apparatus is provided for each of the reader/writer unit and the memory module. In the electromagnetic induction coupling apparatus of the reader/writer unit, a transmitting coil and a receiving coil are coaxially wound around a single magnetic core. In the electromagnetic induction coupling apparatus of the memory module, a single coil which is commonly used for transmission and reception is wound around a single magnetic core. A reception signal of the transmitting/receiving coil of the memory module is rectified and smoothed by a power source circuit, thereby forming an operating power source of the memory module. The power source circuit has a backup capacitor.

Abstract: The bidirectional transmission to write or read out data is executed between a read/write unit and a memory module by the contactless electromagnetic coupling using induction coils. A spread spectrum communication technique is used in at least the up transmission to transmit data from the memory module to the read/write unit in the bidirectional transmission. Two kinds of chirp waves or M series having little correlation are used in the spread spectrum communication. For instance, in the case of using the chirp waves, on the transmission side, two kinds of chirp waves having little correlation are prepared and either one of the chirp waves is transmitted in correspondence with the data bit 0 or 1. On the reception side, the correlation between the reception signal and each of the reference values of the two kinds of chirp waves which have previously been stored is calculated and the data bits 0 and 1 are demodulated on the basis of the result of the calculation.

Abstract: In response to a bit transfer request from one of two units, bit data is transmitted bit by bit from the other of the two units. The unit on the transmission side for transmitting the bit data has an M-series generator. In response to bit 1, a first M.sub.0 -series signal of a 63-word length is generated. In response to bit 0, a second M.sub.0 -series signal in which the series start position is set to the intermediate position of the first M.sub.0 -series signal, although the signal is the same M.sub.0 -series signal of the 63-word length, is generated. The unit on the reception side has previously stored the first and second M.sub.0 -series signals on the transmission side as reference signals, and calculates the correlations between the two reference signals and the reception signal, and demodulates the data bit corresponding to the reference signal having a larger correlation value.

Abstract: A control signal used to write access or read access and data are transmitted between a write/read unit and a memory module by a contactless coupling using induction coils. The write/read unit multiplexes a control signal consisting of three signals including a power source signal, sync clocks, and enable clocks using frequency modulation and supplies the resultant multiplexed signal to one end of the induction coil for transmission. The write/read unit frequency modulates access data and supplies same to the other end of the same induction coil for transmission. The transmitting coil in the memory module allows the signal which is obtained by adding an access signal to the control signal to be induced in the coil for reception in the write/read unit. The read data from the memory module is frequency modulated and sent from the memory module to the write/read unit by using the transmitting and receiving coils for a down-signal which is used only to read out data.

Abstract: A control load such as a cylinder or the like is driven at a constant speed by controlling the flow rate of a variable delivery pump. The control mode is switched to the pressure control to keep the stop pressure constant on the basis of an increase in pressure when the control load stops. A remaining delivery amount which will be necessary to raise the delivery pressure to an object stop pressure when the load stops and an excess delivery volume due to the operation time lag when it is assumed that the delivery by the pump is stopped at the present time are predicted. When they coincide, the delivery amount of the pump is set to zero and the control mode is switched to the pressure control. On the other hand, the product of a load volume and a fluid compressibility is calculated from the increase in pressure when the load stops. The feedback gain of the pressure control is controlled on the basis of the calculated value of this product.

Abstract: Between two units which are separately arranged, a power source signal is supplied from one of the two units to the other unit via electromagnetic induction coupling by using induction coils, and data signals are mutually transmitted and received between both of the units. A change in coupling distance between the induction coils provided for the two units is detected from a signal level of a reception signal from the unit which receives the power supply. When the reception signal level decreases, the signal level of the power supply signal is increased.

Abstract: An optical multiplex communication system in which n kinds of digital signals whose logical levels do not simultaneously become true, such as, pulse motor controlling pulses, are multiplexed through a single optical fiber line. The transmitting end generates n kinds of carrier clock signals of different frequencies by clock generating means, produces the respective logical products of the carrier clock signals and the digital signals and then produces a logical sum of the logical product outputs by logical circuits and converts the logical sum output to a light signal by a light transmitter, thereby delivering the light signal onto the single optical fiber line.

Abstract: Drive data such as vehicle velocity, engine rotational speed, and the like are recorded into a memory module in a state in which the memory module is attached to a vehicle. When drive management data is made, the memory module is detached from the vehicle and set to a read unit. When the read unit reads out the drive data recorded in the memory module, the drive management data such as drive period of time, rest period of time, maximum drive speed, drive distance, and the like are calculated on the basis of the readout data. The drive records classified every driver or every vehicle are automatically made.

Abstract: Controlled variable table data, which consist of pulse number data corresponding to the maximum controlled variable of a fluid valve and divided into N divisions in each of which given pulse number data are set, are stored in a memory so that the sum of the given pulse number data in the N divisions may be equal to the number of pulses for giving a given controlled variable to the fluid valve. On the other hand, period table data, which consist of pulse interval data divided into divisions corresponding in number to the divisions of the controlled variable table data for determining a given control pattern, are stored in another memory.
