Abstract:
A hybrid vehicle is provided in which, since the driving force of a generator/motor (M1) disposed so as to surround the outer periphery of an input shaft (16) of a transmission (T) is transmitted to an output shaft (17) of the transmission (T) via an endless chain (78), it is possible to carry out the so-called leg shaft drive, in which transmission of the driving force between the generator/motor (M1) and the output shaft (17) is carried out without going through an engine (E) and the input shaft (16), thus reducing power consumption and enhancing energy recovery efficiency during regenerative braking. Furthermore, since a crankshaft (15) of the engine (E) and the input shaft (16) of the transmission (T) are disposed coaxially, and the generator/motor (M1) is disposed at a position sandwiched between the engine (E) and the transmission (T), it is possible to employ the same layout for the generator/motor (M1) as for a conventional sandwiched generator/motor, and the leg shaft drive system can be employed without greatly modifying the design of the transmission (T).

Abstract:
An information providing center calculates an estimated traveling time to elapse before a vehicle arrives at a destination by using traveling information transmitted from an on-vehicle system and determines contents information to be provided to the on-vehicle system in conformance to the calculated traveling time. The information providing center prepares a program list containing the contents information that has been selected, information indicating the order in which the contents information is to be played and media information indicating how the contents information is to be obtained and transmits the program list to the on-vehicle system. The on-vehicle system obtains and plays the contents information as indicated in the transmitted program list.

A semiconductor integrated circuit has a chip check circuit for detecting cracks and other defects in the chip during operation. The chip check circuit extends in the chip from an input terminal to an output terminal so as to scan a predetermined wide area. The chip check circuit has at least one signal line extending near or within a circuit block in the chip so that the signal line can be broken together with the circuit block. The chip check circuit may further comprise one or more inverters, and/or one or more two-wire logic circuits.
Abstract:
An equipment for displaying a specification of behavior of a real time system includes a program memory for storing a plurality of program objects for simulating operations of objects indicative of an arrangement of the real time system and a plurality of graphical symbol objects for expressing operational states of the objects and relationships between the objects in the form of a graphical symbol representation on a display screen. In the equipment, the plurality of program objects are linked with the plurality of symbol objects through an inter-program communication control routine. Each of the program objects, when receiving a message from the communication control routine, is executed for simulation operation according to the received message to thereby generate a new message to be sent to the associated program routine and a new message indicative of an object state change to be sent to one of the symbol objects corresponding to the associated object. Each of the symbol objects, when receiving the message from the communication control routine, is executed to change a display state of one of symbols corresponding to the associated symbol object on the display screen.
Abstract:
A fuel injection pump includes a reciprocating plunger and a control sleeve slidably fitted over the plunger, the prestroke of which is varied by vertical movement of the control sleeve. The control sleeve is provided at its upper end with a fuel discharge groove, through which the fuel contained in a fuel-pressurizing chamber is discharged after the end of injection. The control sleeve also has to pressure escape passage. A variation in the effective stroke allows the pressure of fuel contained in the fuel-pressurizing chamber to be selectively regulated by the pressure escape passage, thereby controlling the pressure of fuel to be injected.
