摘要:
A fuel supplying apparatus of an internal combustion engine includes a first fuel supply system, a second fuel supply system, and a pulsation propagation suppressing unit. The first fuel supply system pressurizes a fuel by a low-pressure pump, and supplies the fuel pressurized by the low-pressure pump to a first fuel injection mechanism. The second fuel supply system is branched from the first fuel supply system, further pressurizes the fuel, pressurized by the low-pressure pump, by a high-pressure pump that is driven according to an operating state of the internal combustion engine, and supplies the fuel pressurized by the high-pressure pump to a second fuel injection mechanism. The pulsation propagation suppressing unit is provided in at least one of the first fuel supply system and the second fuel supply system, and suppresses propagation of a pulsation generated in the high-pressure pump to the first fuel injection mechanism.

Provided is a light guide plate having a simple structure that allows an effective emission area to be large and shows a reduced unevenness in brightness in an emission region near to an incidence side face as well as a reduced dropping in brightness in an emission region remote from the incidence side face. The light guide plate is used to provides a surface light source device and an image display employing the device for illuminating an image display panel. In the incidence side face of the light guide plate, a generally central region is formed of a high light dispersing ability area (rough area). The high light dispersing ability area is sandwiched by low light dispersing ability areas (flat and smooth areas or rough areas having a small surface roughness). The high light dispersing ability area is formed in a range including a region irradiated by a center LED of three LEDs.

A card read/write apparatus for reading or writing information from or into an IC memory region of a card comprises a card carriage formed with an IC exposure opening through which the IC memory region of the card is exposed when the card is placed on the card carriage, and a contact device having contact pins that is protruded into or retracted from the IC exposure aperture while being maintained to be in parallel with the IC memory region of the card so as to contact with or move away from the IC memory region of the card which is exposed from the IC exposure aperture.

In a radio telephone scheme in which each of radio systems transmits a system identification code, and each radio system offers a service for a radio terminal, system identification codes of a plurality of radio systems, from which a user gets the service, and selection priorities corresponding to the system identification codes are stored. When a plurality of stored identification codes are received, a radio system having a system identification code, of the stored system identification codes, which corresponds to a highest selection priority is selected.

A radio connection system capable of improving the number of successfully completed connections between base stations and mobile stations, without resorting to complicated control systems and, therefore, desirably obtaining dynamic channel assignment. A base station transmits a proposed available radio frequency to a mobile unit which has issued a connection request and then waits to receive an answer from the mobile unit in any slot timing at the proposed radio frequency. The mobile unit detects a time slot which it can use and returns an answer to the base station in that time slot.

A bill discriminator including within a housing a bill conveying mechanism which comprises a bill conveying path, a driving pulley, a driven pulley and conveyor belt and which is rotatable in both forward and reverse directions for conveyance of a bill within the bill conveying path, and bill discriminating magnetic head and photo sensors disposed in the bill conveying path, characterized by further including a tiltable lever having a pressing roller which is brought into pressure contact with the magnetic head by a biasing force of a spring, a latch gear integral with the driven pulley of the bill conveying mechanism, and a rocking lever which is normally in pressure contact with the outer periphery of the latch gear and which, at the time of reverse rotation of the bill conveying mechanism, imparts a tilting action to the tiltable lever against the spring to let the pressing roller depart from the magnetic head.
