Abstract: A heating body is provided. The heating body utilizes a heating composition that generates heat when it is brought into contact with oxygen in the air and being controlled easily and correctly in heating temperatures (heating properties). (1) The heating body includes a heating composition housed in a flat air permeable flat bag using an air permeable packaging material formed on one side or both sides thereof. In the heating body, air permeable pores are formed on the packaging material by irradiation of laser rays. The air permeable pores have diameters or circle-corresponding diameters of 0.005 to 2.0 mm. A distance between the centers of the air permeable pores adjacent to each other is 0.1 to 20 mm. The percentage of the area of the air permeable pores to the total area of the laminate sheet is 0.001 to 5%. (2) In the heating body according to the above Item 1, the heating composition may be held by a sheet-like support.

Abstract: The present invention provides an expandable heating sheet which does not lose its expansion property even when a heating composition thereof is hardened due to reaction with oxygen, which can be used while being fitted to a bendable portion such as an elbow or a knee, and which can be easily manufactured with efficiency, and a heating sheet bag in which the expandable heating sheet is hermetically sealed.

Abstract: An acoustic signal processing apparatus and an acoustic signal reproduction system capable of separately and simultaneously outputting more than six-channel audio signals including a sub-woofer without increasing the number of audio signal output terminals are provided. An acoustic signal processing apparatus includes a signal processing unit (decoding unit and downmixing unit) which decodes an audio input signal that is in a predetermined format and outputs eight-channel audio signals and downmixed two-channel audio signals, a first output unit which separately outputs the six-channel audio signals from among the eight-channel audio signals outputted by the decoding unit, and a second output unit which selects and outputs, based on an external setting, one of the two-channel audio signals other than the six-channel audio signals outputted by the first output unit and the two-channel downmixed audio signals outputted by the downmixing unit.

Abstract: The present invention provides a semiconductor device with which it is possible to easily realize an information processing function according to an intended application while it is possible to suppress an increase in the management costs when, for example, making a change to the function, wherein a processing function setting section stores information unique to the semiconductor device, e.g., the product number or the version number of the semiconductor device, as information that indicates which one of a plurality of processing functions of a processing section should be enabled. A processing function control section performs a function control operation so that a predetermined processing function of the processing section is enabled according to information stored in the processing section.

Abstract: When the filtering is necessary, a filtering operation section performs a filtering operation on received data in response to a control signal output from a filtering on/off control section to generate data to be output. On the other hand, when the filtering is unnecessary, an output selection section extracts specified delay data out of the delay data stored in the delay buffer in response to a control signal output from a filtering on/off control section and outputs the extracted data.

Abstract: The present invention provides a measuring apparatus and method for measuring the quantity of ventilation, whereby the quantity of ventilation correlates to the heating characteristics. [The present invention is also] able to measure the quantity of ventilation of a gas permeable packing material used in heating packets in a short period of time, regardless of the type or pore diameter of the packing material. The present invention provides heating packets displaying stable heating characteristics. In the present invention, one surface of a gas permeable packing material is exposed to the atmosphere, while the opposite surface is scavenged with a carrier gas which does not include oxygen. The present invention measures the oxygen diffusing capacity, [as the diffusion of oxygen] from the atmosphere through the gas permeable packing material, by measuring the concentration of oxygen in the carrier gas after scavenging.

Abstract: The heating packet of the present invention comprises an air-permeable bag containing a heat-generating composition or a sheet-like heat-generating body which generates heat upon contacting oxygen in air. The heat-generating composition or the sheet-like heat-generating body contains zinc powder instead of iron powder. By the use of zinc powder, the heat-generating composition and the sheet-like heat-generating body can be maintained flexible during the use of the heating packet or after heat generation.

Abstract: A trigger capable of causing crystallization of regenerative substances. A regenerative body includes the trigger which includes a plurality of secured elastic flat elements and the regenerative substances, when in a supercooled state, receive a physical stimulus from the trigger.

Abstract: A cooling agent which cools by an endothermic reaction resulting from the dissolving of crystals of inorganic salts water, the salts crystallizing at about room temperature by supplying heat. The cooling agent comprises a mixture of (i) a sodium phosphate salt, (ii) a sodium ammonium phosphate salt or an ammonium phosphate salt, and (iii) water. The cooling agent is produced in a manner which avoids the conglomeration of the crystals, which was a difficulty in the art. Moreover, the cooling agent of the present invention can be used repeatedly. When a nucleating agent, a highly water absorbent polymer or a thickener is added to the cooling agent, the precipitation of the crystals occurs in a still finer and stabler state. The cooling agent can be used in a cooling pillow having a desirable cooling property and a soft and agreeable touch, which offers comfort with safety and which is free from conglomeration of crystals, even after a long period of time.

Abstract: A refrigerant containing two or more constituent components that exhibit an endothermic action when mixed with each other, the refrigerant including, as the constituent components, an inorganic salt and a salt hydrate containing at least a hydrate of strontium hydroxide. The refrigerant has a superior cooling capability such as a low attainable cooling temperature and a long duration of the cooled state, and also has no fear of melting or deterioration even where the atmospheric temperature is increased during storage.

Abstract: A process for producing a glass fiber-reinforced molded sheet by impregnating glass fibers with a resin syrup and thereafter hardening the resin syrup with which the glass fibers are impregnated, wherein the resin syrup is 20 to 35% by weight vinyl aromatic hydrocarbon and comprises 25 to 50 parts by weight acrylonitrile-vinyl aromatic hydrocarbon copolymer and 75 to 50 parts by weight acrylic acid, methacrylic acid, methacrylic acid ester, acrylic acid ester or mixtures thereof, the copolymer comprising 10 to 50 parts by weight acrylonitrile and 90 to 50 parts by weight vinyl aromatic hydrocarbon and having a viscosity average molecular weight of 30,000 to 100,000.
