A main cooling circuit is formed by an engine, a radiator and a first pump. A hot water circuit is formed by the engine, a heater core and the first pump. A heat storing water circuit is connected between a bifurcating point of the hot water circuit and the engine, wherein a second pump and a heat storage tank are provided in the heat storing water circuit. Engine cooling water stored in the heat storage tank is circulated by the second pump, so that the hot water is supplied to the engine before the engine operation is started. The engine cooling water is also circulated by the second pump during the engine operation, so that hot water is stored in the heat storage tank.

A heat storage tank includes a tank body having a cylindrical opening portion at one end side, and a coolant passage portion for defining therein flow passages communicating with the tank body. The tank body stores a coolant of a liquid-cooled engine therein while being thermal insulated, and the coolant flows into and flows out of the tank body through the flow passages. The coolant passage portion includes an insertion portion that is inserted into the opening portion in its axial direction. At least two O-rings are provided between the opening portion of the tank body and the insertion portion to seal a clearance therebetween, and are lined in the axial direction to be separated from each other in the axial direction by a predetermined distance. Accordingly, the heat storage tank can improve sealing performance of the coolant.

In a heat storage tank, an elbow pipe member defining a water introduction passage is formed by connecting an inlet-side cylinder portion and an outlet-side cylinder portion to have a corner portion. A step portion is disposed in the water introduction passage around a position where center lines of both the cylinder portions are crossed with each other. The step portion has a collision surface that is set to cross with a line parallel to the center line of the inlet-side cylinder portion, so that water introduced from the inlet-side cylinder portion collides with the collision surface of the step portion.

A processor loads a program from a main memory, detects a register updating instruction, and registers the address of the register updating instruction in a register-producer table storing unit. Moreover, the processor loads the program to detect a memory access instruction, compares a register number utilized by the detected memory access instruction with a register-producer table to specify an address generation instruction, and rewrites an instruction corresponding to the address generation instruction.

An air conditioning apparatus for a vehicle includes a front air-conditioning unit for adjusting a temperature of air blown toward a front seat side in a passenger compartment, and a rear air-conditioning unit for adjusting a temperature of air blown toward a rear seat side in the passenger compartment. In the front air-conditioning unit, a ratio between an amount of air passing through a front heater core and an amount of air bypassing the front heater core is adjusted by an air mixing door, and the temperature of air blown toward the front seat side in the passenger compartment is adjusted by the rotation of the air mixing door. On the other hand, in the rear air-conditioning unit, a flow control valve for controlling a flow rate of hot water flowing into a rear heater core is provided, and the temperature of air blown toward the rear seat side in the passenger compartment is adjusted by the flow control valve. Thus, the air conditioning apparatus has a downsized rear air-conditioning unit while preventing air-conditioning capacity for the passenger compartment from being lowered.

In a vehicle air conditioner, inside air and outside air are switched by first and second inside/outside air switching doors. The first inside/outside air switching door is operated by a first door lever operatively linked with an inside/outside air operation member of an operation panel. On the other hand, the second inside/outside air switching door is operated by a second door lever which is operated by a mode operation lever operatively linked with a mode operation member of the operation panel, a temperature-adjustment operation lever operatively linked with a temperature-adjustment operation member of the operation panel, and an elastic force of a spring. When an air outlet mode except for a defroster mode is manually set by the mode operation member, and when maximum heating is manually set by the temperature-adjustment operation member, the second inside/outside air switching door is operated to an inside air introduction state by the second door lever.

In an air conditioner for a vehicle, a temperature control unit includes a first air mixing door for adjusting an opening degree of a cool air passage through which air having passed through an evaporator bypasses a heater core, and a second air mixing door for adjusting an opening degree of an air inlet portion of the heater core. At least the second air mixing door between the first and second air mixing doors is a butterfly door having a rotation shaft at a center in a door width direction. When an inside/outside air double-layer flow mode is set, the second door partitions an air passage between the evaporator and the heater core into a first air passage through which outside air flows and a second air passage through which inside air flows while fully opening the air inlet portion of the heater core. Thus, in the air conditioner, a distance between the evaporator and the heater core is reduced while partition performance between inside air and outside air due to the second air mixing door is improved.

An information processing system performs a prefetch for predicting data that is likely to be accessed by a central processing unit, reading the predicted data from a main memory, and storing the data in a cache area in advance. The information processing system includes a usage information storage unit that stores therein usage information indicating whether prefetched data has been accessed; and a usage information writing unit that writes the usage information of the prefetched data in the usage information storage unit.

A packet communication control device transfers a control packet and a data packet and includes a plurality of sending units and a multiplexer which separates a data communication path and a control communication path, multiplexes the control packets and transfers the multiplexed control packets by the control communication path and the data packet by the data control path. The average Round Trip communication time can be shortened and the hardware cost can be reduced because the Shortest-Job-First control is implemented by separating data communication pathway from control communication pathway logistically or physically, and also multiplexing the control communication pathway with control packet.
