摘要:
A heat exchanger, in which an alternating flow of supply air and exhaust air are supplied in opposite directions between a plurality of stacked heat exchanging members, is characterized in that the heat exchanging members each is composed of a first paper member having a moisture permeability and corrugated in the width direction and having flat portions at the longitudinally opposite ends flattened under pressure, and a pair of second paper members having one end joined to the flat portions and the other end side extending flatly in the longitudinal direction to define a header defining portion for defining a header portion, so that the number of the parts can be decreased and the assembly can be made easier, whereby a heat exchanger with an improved productivity can be provided. A method for manufacturing a heat exchanger is also disclosed.

A broadcast receiving terminal is equipped with a receiving unit for receiving a broadcast signal; a separating unit for separating audio coded data and band expansion information from the broadcast signal received by the receiving unit; a low frequency band audio decoding unit for decoding the audio coded data so as to output low frequency band audio data; a high frequency band audio producing unit for producing high frequency band audio data by employing the band expansion information and the low frequency band audio data; a switching unit for switching a sound reproducing mode of the broadcast receiving terminal between a first mode for reproducing sound based upon both the low frequency band audio data and the high frequency band audio data, and a second mode for reproducing sound based upon only the low frequency band audio data; and a control unit for controlling the switching unit so as to constitute a mode selected in response to a predetermined condition.

A semiconductor element housing package includes a substrate, a frame body disposed on the substrate; an insulating substrate disposed in a frame-body-surrounded region of the substrate; a first mounting member disposed on the insulating substrate, for mounting a power semiconductor element thereon; a second mounting member disposed on the insulating substrate so as to be spaced away from the first mounting member; a first lead member having a first bend; and a second lead member having a second bend. The first lead member is disposed so as to pass through the frame body from an exterior thereof and extend over the first mounting member and makes connection therewith through the first bend. The second lead member is disposed so as to pass through the frame body from the exterior thereof and extend over the second mounting member and makes connection therewith through the second bend.

An electronic appliance is equipped with: a voice processing unit for executing one voice processing operation selected from plural sorts of voice processing operations; a zapping detecting unit for detecting a zapping condition; and a process switching unit for switching the presently executed voice processing operation to a different voice processing operation in response to a detection result for indicating whether or not the zapping condition is detected. When the zapping detecting unit detects the zapping condition, the process switching unit controls the voice processing unit to switch the presently executed voice processing operation to a voice processing operation which does not contain a sound quality improving function.

A sealed connector is provided which includes: an inner housing accommodating a terminal; an outer housing surrounding the inner housing; a metallic shield positioned between the inner housing and outer housing; a connecting portion connecting the inner housing and the outer housing to form a one-piece body; a shield insertion hole which is formed for communication of the interior of the sealed connector with a shield insertion space located between both inner and outer housing; and a connecting protrusion which is formed by notching at the pointed end of the metallic shield and which protrudes in the connector fitting direction through insertion of the metallic shield into the shield insertion space. The metallic shield includes a slit adjacent to the connecting protrusion and an engaging piece opposite to an engaging slot portion of the inner housing, wherein the bottom end portion of the slit contacts the connecting portion between the inner and outer housings. Each of the slits of the metallic shield accomodates the connecting protrusions of the other metallic shield which are alternately fitted into each other resulting in an elimination of the clearances when the male- and female-side sealed connectors are fitted into each other.

A broadcast receiving terminal having a calculating process unit operated at different clock frequencies in response to modes executes a mode switching method comprising the below-mentioned steps. The mode switching method is comprised of: a step for judging whether or not a mode switching instruction is issued while the calculating process unit is operated; a step for setting the calculating process unit to an idling status when the mode switching instruction is issued; and a step for releasing the idling status of the calculating process unit.
