Abstract: A communication device includes a communication circuit mounted on a printed substrate and having a heat generating element; a shield casing covering the communication circuit and shielding electromagnetic waves; a housing accommodating the shield casing and the printed substrate; a heat diffusing member mounted along an inner wall of the shield casing diffusing heat in a planar direction; and a heat insulating layer disposed between the shield casing and an inner wall of the housing.

Abstract: A fuel injection control apparatus for a diesel engine (1) is provided that eliminates a torque step occurring when shifting from a pilot fuel injection mode to a normal injection mode. After finding a total fuel injection quantity QFIN per cycle (block 101), a pilot fuel injection quantity QPILOTB is subtracted therefrom to determine a pilot fuel injection quantity QPILOT and a main fuel injection quantity QMAIN (block 103). Corrected pilot fuel injection quantity QPILOTF and corrected main fuel injection quantity QMAINF are determined using a fuel temperature correction coefficient KQTHF and a pilot fuel injection thermal efficiency CEHPILOT (block 104) and a main fuel injection thermal efficiency CEHMAIN (block 105). The thermal efficiencies are established based on the respective injection timings. A change in torque does not occur because the change in the thermal efficiency caused by the injection timing is offset.

Abstract: When a housing device for an SIM card 600 is equipped with a mobile telephone 500, a objection 420 pioviel on an operational lever 400 can be seen from a lever hole 511 provided in the housing 510. In this way, it is possible to slidably displace a cover 300 of the housing device of the SIM card 600 which is housed within by moving the projection 420 with a finger or the like. Furthermore an SIM card insertion/detachment aperture 512 provided in said housing 510 is positioned on an extension of a container 120 of a body 120 in the SIM card insertion/detachment device. When the SIM card 600 is inserted from the SIM card insertion/detachment aperture 512, the card may be contained in the container.

Abstract: A housing for a portable radio telephone device to which a part thereof is exposed externally at a position recessed from an outer surface of a portable radio telephone device so that the part does not contact the skin whereby heat generated within the portable radio telephone device is efficiently radiated outside and a reliable operability is provided without the outersurface portions to thereof become too hot or cold to comfortably hold by hand.

Abstract: Method for manufacturing glazed cement products of a foam light-weight aggregate, reinforcing steel under pretension or a stress-absorbing layer around the reinforcing steel. An action of generating crack, caused by a difference of coefficient of thermal expansion between the reinforcing steel and a portion of cement material while burning and cooling are carried out, is absorbed by the foam light-weight aggregate, the stress-absorbing layer or pretension given to the reinforcing steel. A reaction of unreacted cement component is promoted by the hydration to harden for recovering mechanical strength.
