摘要:
A network system having a plurality of data transmitters and receivers interconnected to a data transmission line and to a time series code string signal transmission line. In the network system, a first pulse train signal according to a predetermined time series code is produced and sent on the time series code string signal transmission line. In each data transmitter and receiver, the first pulse train signal is received and demodulated to form an intermediate synchronization signal and a plurality of predetermined code string patterns. When one of the plurality of predetermined code string patterns accords with a predetermined address code in one of time slots, either data transmitter or data receiver transmits or receives a data of a predetermined number of bits in a Non-Return To Zero code to or from the data transmission line in synchronization with a data transmission and reception enable clock signal predetermined by a data transmission and reception enable clock (oscillator) whose frequency variation is corrected by means of the intermediate synchronization signal one time or a plurality number of times by a predetermined number of bits of data so that a reliable data transmission without synchronization deviation between the data transmitter and data receiver(s) and without generation of high frequency noise can be achieved.

The present invention relates to a metal oxide-platinum compound catalyst comprising 5 to 95 parts by weight of a metal oxide and 95 to 5 parts by weight of platinum as the balance. The platinum has a form to reticulately cover at least a part of a particle of the metal oxide. The wires constituting the platinum mesh have an average wire diameter of 5 nm or smaller.
摘要:
A time-division multiplex transmission network system applicable to an automotive vehicle in which each data transmission station constituting the whole network system together with data reception stations is activated to transmit a data only when an address (station identification information) allocated thereto coincides with one of the series of information on the specification of a pair of stations between which the data is communicated. Consequently, discharge of a battery whose electric power is distributed into all data transmission and reception stations can remarkably be reduced since other transmission and reception stations are deactivated during the time slot at which the address allocated to the pair of transmission and reception stations coincides with the one information for specifying the data communication stations.

Provided is a lithium ion capacitor that can maintain a high capacity retention rate and suppress an increase in internal resistance even after high-load charging-discharging is repeated many times and that has long service life because the occurrence of a short circuit due to precipitation of lithium on the negative electrode is prevented.The lithium ion capacitor comprises a positive electrode, a negative electrode, and an electrolyte solution, the negative electrode including a current collector and electrode layers that contain a negative electrode active material and are formed on front and back surfaces of the current collector, wherein, in the negative electrode, ratios of deviations of respective thicknesses of the electrode layers formed on the front and back surfaces of the current collector from an average of the thicknesses of the electrode layers to the average is −10 to 10%.
摘要:
A circuit for detecting an abnormal transmission state on a signal transmission line, the abnormal state being such that a short-circuit or open-circuiting occurs in the signal transmission line, applicable to a time-division multiplex transmission network system having an address clock line and a data transmission line. The circuit includes a first latch circuit, which is set by a trailing edge of a data receivable interval specification pulse to a state indicating no presence of the specification pulse, wherein the specification pulse is derived from an address coincidence circuit constituting one data receiver of the network system. The first latch circuit latches the state of presence or absence of the specification pulse on a trailing edge of a start bit constituting data to be received. The circuit further includes a second latch circuit which is initially set to a state indicating the state of the presence of the specification pulse and which latches the state of presence or absence of the specification pulse latched in the first latch circuit at a time when a duration of the specification pulse continues and which operates with a slight delay with respect to the appearance of the trailing edge of the start bit on the data transmission line.

A wiper control system includes measures an elapsed time of operation cycle, through which a wiper blade assembly performs one cycle of wiper operation. The wiper control system resets the measured elapsed time when ever the wiper blade assembly reaches a predetermined position. On the other hand, wiper control system detects the measured elapsed time exceeding a given period of time to initiate a predetermined fail-safe operation. In practice, the fail-safe operation is performed to intermittently drive the wiper motor with an interval which is long enough to sufficiently cooling off the wiper motor, when fail-safe operation is performed while wiper system is maintained ON, and to terminate driving of the wiper motor when the wiper system is turned OFF.
