An air-conditioning control system (1) includes: an air conditioner (10) having an outer air cooling coil (11) for cooling outer air and a return air cooling coil (12) for cooling return air in a room; a central heat source device (40) for supplying cold water to each coil (11, 12) of the air conditioner (10); and an air-conditioning linkage controller (50) for calculating a set value of the air conditioner (10) so that the total necessary consumption energy in the air-conditioning control system (1) is the minimum value within a preset range of a comfort index.
摘要:
Epoxy resin compositions comprising (a) an epoxy resin, (b) a latent curing agent with curing power at 100° C. or below and (c) an aromatic amine-based curing agent and/or an alicyclic amine-based curing agent, which are curable in two stages, or epoxy resin compositions further comprising (d) a curing accelerator, as well as a prepregs comprising reinforcing fiber materials impregnated with the epoxy resin compositions. The compositions give die-releasable cured products by primary curing at low temperature, give highly heat-resistant cured products by secondary curing, and exhibit satisfactory stability at room temperature.
摘要:
A holder sheet device (100, 200) to securely hold boxes (50) together on a flatcar is disclosed, comprising at least one elongated sheet member (101, 102, 201), anchor belt (3, 23), and fastener (4, 24). Optionally, the holder sheet device is further provided with elastic connector (10). The anchor belt is spanned over the boxes and holds a portion of the holder sheet device so that a single worker can easily mount and set the holder sheet device on the boxes.
摘要:
Fuel in a fuel tank is pressurized by a fuel pump and supplied to a fuel gallery. When a fuel injection valve connecting with this gallery is opened by an electromagnetic signal, fuel is injected from the valve into a combustion chamber of the engine. The fuel gallery is formed inside a cylinder head, and the fuel injection valve is disposed in the cylinder head such that a fuel inlet port of the valve faces the gallery. In this manner, a high pressure fuel passage does not project outside the cylinder head, and there is less risk of fuel leaking from the passage. Further, as the high pressure fuel passage does not project outside the engine, the piping around the engine is simplified.

In a spark-ignition internal combustion engine, during low engine temperature or battery voltage, additional fuel is introduced into the mixture supply system of the engine and, following a predetermined time delay, the cranking motor of the engine is actuated to start the engine.
摘要:
An engine spark timing controlling device using a resonant type vibration sensor having mechanical resonance characteristic near the knocking frequency of an engine. The vibration sensor is arranged on a body of an engine and the sensor output signal is processed and the spark timing is adjusted to obtain an optimum knocking condition.
摘要:
Control of secondary air flow to a reactor during normal operating condition of an engine is provided by relieving a predetermined portion of the secondary air discharged from an air pump to a point intermediate the reactor and a muffler installed downstream of the reactor. When the engine is operating under heavy load and/or at high speeds, all of the secondary air from the air pump is supplied to the reactor, while when the engine is operating at full load all of the secondary air from the air pump is relieved to the ambient atmosphere.
摘要:
A process for preparing coloring caramel from a pre-gelatinized starch or dextrin. The process comprises preparing a pre-gelatinized starch or dextrin having a specified moisture content and having a specified acidic pH value and extruding it at an elevated temperature and pressure condition effective to caramelize it.The extruded caramel product may be pulverized to yield a powdered caramel.
摘要:
A combustion arrangement which enables combustion with high EGR comprises an ignition means positioned within an area which is disposed in the neighborhood of a location at which the thickness of the combustion chamber is the maximum and adjacent the cylinder axis.
