摘要:
An air-conditioning apparatus forms a refrigerating cycle with a refrigerant heater and a compressor having two cylinders. The apparatus simultaneously carries out a refrigerant heating operation and a heat pump operation when a required heating capacity is high, and when the required heating capacity is low, only the heat pump operation. This operation technique helps reduce the size of the apparatus and expand a variable width of heating capacity. The apparatus also has a defrosting unit for defrosting an outdoor heat exchanger during the heat pump operation.

An outdoor unit comprises a combustion unit for presenting combustion heat, a heating medium heating part for heating the heating medium with the combustion heat to vary in phase from liquid to gas, and a heating medium transferring part. A plurality of indoor units each have an indoor heat exchanger and a required heating capacity detecting part for detecting a required heating capacity in a region to be heated required for the indoor heat exchanger. The detecting part comprises a room temperature setting part, a room temperature detector, and a required heating capacity data output part for delivering required heating capacity data in the region to be heated depending on the difference between the preset room temperature and the detected room temperature. The distributing part couples the plural indoor units parallel to the outdoor unit so as to form individual enclosed heating medium circulation cycles. The controller controls the combustion quantity of the combustion unit and the heating medium transferring capacity according to the sum of the required heating capacity data, and controls the heating medium distribution amount of the distributing part for distributing the heating medium into each indoor heat exchanger depending on the ratio of the required heating capacity data.

A toxic gas exhaust suppression-type combustion system burns a hydrocarbon-based fuel and comprises, an incomplete combustion section for causing incomplete combustion by supplying the fuel and a small amount of air, a solid component removing section, connected to said incomplete combustion section, for collecting and removing a solid component, such as soot, within an unburned gas generated by said incomplete combustion section, and a complete combustion section for perfectly burning a remaining unburned gas by supplying a sufficient amount of air, the remaining unburned gas being obtained by removing the solid component from the unburned gas generated by said incomplete combustion section by flowing the unburned gas through said solid component removing section.
摘要:
A pair of pulsating combustors are parallelly connected to each other between an air intake chamber and an exhaust chamber. Aerodynamic valves having a forward flow coefficient higher than their reverse flow coefficient are respectively arranged in air intake pipes which connect the combustion chambers of the pulsating combustors to the air intake chamber. Fuel is injected into a location between each of the aerodynamic valves and a corresponding one of the combustion chambers. The injected fuel collides with an air stream flowing through each of the aerodynamic valves and is mixed therewith. When explosive combustion takes place in any one of the combustion chambers, injection of fuel thereto is automatically stopped by the pressure increase caused by the explosive combustion. When the pressure in the combustion chamber decreases, fuel is once again injected.

A print image forming apparatus includes: an obtaining unit that obtains a document having at least one page; a color information generating unit that generates color information from an identifier allocated to and associated with the obtained document according to a predetermined rule; and a forming unit that forms an image to be output, in which the identifier represented by a color which is in accordance with the generated color information is added to the document.
摘要:
A fuel cell system is disclosed that includes a heat exchanger having first and second heat exchanger portions arranged in a fluid flow passage. The second heat exchanger portion is arranged downstream from the first heat exchanger portion. The first and second heat exchanger portions include a coolant flow passage and are configured to transfer heat between the fluid flow and coolant flow passages. The first heat exchanger portion includes a first corrosion-resistant material and the second heat exchanger portion includes a second corrosion-resistant material that is less corrosion-resistant than the first corrosion-resistant material. A collector, which includes a tray and/or a mist trap, is configured to collect acid in the first heat exchanger portion from a gas stream in the fluid flow passage. Collected acid can be sprayed into a gas stream upstream from a flow field of the fuel cell.

A document management system includes: a document producing apparatus including a protected document producing unit; and a document use managing apparatus including: a document information storage; a document information registering unit; a use restriction information storage; and a use restriction information registering unit.
摘要:
The condenser heat exchanger includes a housing that provides a gaseous stream flowpath and a bottom wall. A gaseous stream contains acid. The housing has a fluid inlet configured to introduce a liquid, such as water. A coolant tube is disposed within the housing in the gaseous stream flowpath and provides a coolant path. Acid condenses on and falls from the coolant tube into a collection area that is provided at the bottom wall near the coolant tube. The collection area is configured to maintain storage of a predetermined amount of fluid that includes the liquid, which dilutes the condensed acid.

There is provided a computer readable medium storing a subprogram causing a computer to execute a subprocess that includes a predetermined process performed in response to a call from a caller program and a return process to return the result of the predetermined process to the caller program. The subprocess includes: an address acquisition process that acquires an access destination address to be accessed by the subprogram before executing the return process, the access destination address being assigned to the memory area of the caller program; a determination process that determines whether or not the caller program is a legitimate caller program based on the acquired access destination address; and a termination process that, if it is determined that the caller program is not a legitimate caller program as a result of the determination, terminates execution of the subprocess before executing the return process.
摘要:
A battery pack comprises a battery stack. The battery stack includes a plurality of battery modules that are arranged in parallel in side-by-side relationship; a plurality of couplers each being mounted on a given portion of the corresponding battery module thereby to constitute a coupler-mounted battery module. The couplers are detachably connected to one another to constitute an aligned unit of the couplers. Each of the couplers comprises a plurality of projected pawls provided by one side of the coupler and a plurality of catching recesses provided by the other side of the coupler. The catching recesses catch the projected pawls of an adjacent coupler for forming part of the aligned unit of the couplers.
