    摘要: A computer system measures bus signal distortion and then adjusts certain characteristics of the signal transmitted over the bus, or adjusts other characteristics of the bus or the load on the bus so that signal distortion is reduced. Distortion characteristics that may be measured include signal voltage overshoot and undershoot, and data setup and hold times. Characteristics of the signal and the system that may be adjusted include changing the slew rate of the signal, changing the data setup and hold times, and changing the load impedance on the bus.

    摘要: A system and method for detecting connection of an external device, and for identifying the connected external device. The external device comprises: a first identification pin group consisting of one or more connector pins arranged in the longitudinal direction at one end of the connector; a second identification pin group consisting of more than one connector pins arranged in the longitudinal direction at the other end of the connector; and a control pin assigned for one pin on one end of the connector. In the external device, identification information is formed in accordance with a connection of the control pin and at least one pin among the second identification pin group, and a connection or disconnection of the control pin relative to each pin in the pin groups. When a control signal at the first signal level is supplied to the control pin of the external device through the control signal line, and when the signal level at at least one pin in the second identification pin group is the first signal level, it is assumed that there is normal contact at both ends of the oblong connector, and that the connection for the external device is preferable. The connections of the pins in the first and the second identification pin groups in the connected external device indicate combinations of signal levels. Thus, the identification means can identify the external device by reading the combinations of signal levels at the identification pins.

    摘要: A navigation system includes a navigation center and a plurality of navigation apparatuses each of which has a data storage that stores various information. In this navigation system, data (coordinate data of each of traveling intersections) concerning a recommended route is transmitted from the navigation center to the navigation apparatus, and then route guidance is carried out in the navigation apparatus using the data received from the navigation center. In the case where the navigation apparatus has intersection data for an intersection specified by the data received from the navigation center, the navigation apparatus extracts the intersection data for the intersection from the data storage. Further, in the case where the navigation center does not have intersection data for an intersection specified by the data received from the navigation center, the navigation apparatus establishes the intersection as a newly-built intersection on the recommended route. Then, the navigation apparatus produces route guidance data (which is used for providing route guidance to a user) using the extracted intersection data, and/or intersection data concerning the established newly-built intersection in addition to the information in the data storage.

    摘要: Disclosed is a communicatory navigation system including an information center (150), at least one navigation unit (100) each mounted on a vehicle and communication means for allowing bi-directional data communication between the information center and the navigation unit. Data transmission from the navigation unit to the information center is made during a period of communication that begins when the navigation unit become communicatable with the information center and ends when the bi-directional data communication therebetween is disconnected. The navigation unit is provided with a drive route history memory area (131) and an instrument operation history memory area (132), and data in these memory areas are transmitted to the information center, together with the vehicle current position data and the destination position data. The information center determines a recommended drive route from the current position to the destination, not only with reference to its own database (158) but also taking into consideration the history data. For example, if it is determined that there is a traffic accident or heavy traffic jam in some route, a bypass route is determined and transmitted back to the navigation unit. When the previous drive route indicated by data in area (131) is not found in the database (158), it can be recognized as a newly constructed road for inclusion in the database.

    摘要: An object detecting system detects an object using an FM-CW wave, so that even if either one of rising-side and falling-side peak frequencies is missing, a plurality of objects can be accurately recognized by accurately combining pluralities of rising-side and falling-side peak frequencies. When it is determined that either one of rising-side and falling-side peak frequencies is missing, the combination of the peak frequencies is determined by calculating the missing peak frequency based on a peak frequency which is not missing.

    摘要: A target PES value input from a controller and a value from a PES value calculator which corresponds to the displacement of a magnetic head are synthesized. A coefficient applicator applies a predetermined coefficient K.sub.1 to the above deviation (multiplication), and a variable coefficient applicator applies a coefficient K.sub.a to the resulting value. The coefficient K.sub.a is varied and set in the variable coefficient applicator in accordance with a value input from a table. The correspondence between the target PES value and the coefficient K.sub.a used as a feedback coefficient for the PES value is stored in the table in advance so that the coefficient K.sub.a is small when the PES value varies sharply and so that the coefficient K.sub.a is large when the PES value is small. The variable coefficient applicator outputs, to a driver, a value to which the coefficient K.sub.a has been applied in accordance with the value from the table.

    摘要: An anti-thrombogenic substance is immobilized on a base of a medical device to impart anti-thrombogenic properties to the medical device. The method comprises the steps of applying a photo-reactive azide derivative macromolecular material to a base to form a bonding layer, coating the bonding layer with a macromolecular layer composed of a water-soluble photo-crosslinking macromolecular material containing the anti-thrombogenic substance, and irradiating the base with ultraviolet light with the bonding layer and the macromolecular layer formed thereon to develop inter-molecular covalent bonding in the bonding layer. The macromolecular layer containing the anti-thrombogenic substance is thus fixed onto the base. Concurrently, the anti-thrombogenic substance is immobilized in the macromolecular layer which is crosslinked. The azide derivative can be poly-m-azidostyrene, copolymers, of poly-m-aziodstyrene with styrene and copolymers of poly-m-azidostyrene with methyl methacrylate. The water-soluble photo-crosslinking macromolecular material can be a copolymer of a photo-dimeric monomer with a water-soluble monomer or a copolymer of a photo-reactive azide with a water-soluble monomer.
