Abstract:
To provide a method for producing a sensing film for gas sensors by sintering particles comprising a metal or a metal oxide on a substrate, where the sensing film for gas sensors having excellent sensor properties such as sensitivity and responsibility can be easily and simply formed. A nano-meter order particle (100), a dispersant (110) for preventing aggregation of the particles (100), and a scavenger (120) for trapping the dispersant (110) at the sintering are mixed in a solvent (130) to prepare a paste body (140), and this paste body (140) is coated on a base material and fired, thereby forming a sensing film.
Abstract:
In a power supply apparatus for a vehicle, an inverter circuit inputs a voltage from a first battery unit through switches. A smoothing condenser is provided between the first battery unit and the inverter circuit in parallel. A DC-DC converter is provided between the smoothing condenser and a second battery unit to voltage-convert electric energy stored in the first battery unit or the smoothing condenser to supply to the second battery unit, and to voltage-convert electric energy stored in the second battery unit to supply to the smoothing condenser. An electronic control unit controls the DC-DC converter before starting power supply to the inverter circuit, such that the switches are closed after the smoothing condenser is charged to a voltage within a predetermined permission voltage range from the voltage of the first battery unit.
Abstract:
There are provided a first navigation unit (transmitting side unit) 10 having a reader 13 for reading at least map data from a map information storage medium 14 and a controller 15 for controlling a system, and a second navigation unit (receiving side unit) 40 having a controller 41 connected to the control unit 15 through a serial communication line 30, buffer memories 42, 46 for storing therein image data from the reader 13, a display image memory 43 for extracting and copying the data in the range required for displaying from the map data developed on the buffer memories 42, 46, and a display controller 44 for displaying the image data on a display 45. The image data (transfer information) with an identification number of a detailed image concerning a rout selecting point approaching just before is stored in the buffer memory 46 with an enough time margin. At a determined display timing, display command information including the identification number is transmitted from the controller 15 to the controller 41 so that the display unit 45 displays the detailed image based on the image data.
Abstract:
In a spill control apparatus for a fuel injection system in which a sleeve is externally fitted to a rotor, and the position of the sleeve relative to the rotor is used to adjust the communication timing between a port on the rotor and a port on the sleeve, the port formed at the rotor is constituted of a first indented portion formed over a specific angle of rotation and a second indented portion formed to achieve specific spill characteristics. The second indented portion is formed continuous to the front end of the first indented portion in the direction of rotation and the contour of the second indented portion is continuous to the contour of the first indented portion which is constituted of oblique sides which extend toward the front relative to the direction of rotation. The length of the rotor port in the axial direction may be set smaller than the length of the port formed on the sleeve in the axial direction. Thus, it is possible to inhibit the entry of dust particles into the area between the rotor and the sleeve, reducing the incidence of scarring induced on the sliding contact surfaces of the rotor and sleeve, and preventing the seizure of the rotor and the sleeve.

Abstract:
A time-division multiplex transmission network system having a plurality of data processing stations, in which data of a predetermined number of bits is transmitted on a data transmission line for a period of time determined by the number of bits of data by one bit in synchronization with a synchronization signal extracted from a predetermined time series code string signal when one of code patterns derived from the predetermined time series code string signal coincides with a predetermined code pattern indicating an address allocated to one of the individual data stations.
Abstract:
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.
Abstract:
Provided is a navigation technique which allows a person other than a user who received a route guide to operate a navigation device through an interaction process. The navigation device is characterized by being provided with an instruction reception unit, a process unit, and an output unit. The instruction reception unit receives an instruction for a process from an external device. The process unit executes a process in accordance with the instruction received by the instruction reception unit. The output unit outputs output information which is obtained as the result of the process executed by the process unit.
