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 input device is provided in which a selectable object intended by a user is selected temporarily by the proximity position detecting section when the user brings the selection commanding body close to the display screen, and is judged to have been selected as a regular one when the user brings the selection commanding body into contact with the display screen at a position that is within a prescribed distance of the selectable object in a state that the user is notified of its temporary selection.

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.

A path of a virtual sound source moving through a virtual sound field space and move start and end conditions are input and an effective acoustic signal is generated. An acoustic processing device includes a sound source path input section 12 for inputting path data of a virtual sound source, a sound source position calculation section 13 for successively calculating the move position data of the virtual sound source in response to the path data, a sound source distance calculation section 14 for calculating the distance data between a listener and the virtual sound source, a distance coefficient storage section 15 previously storing coefficient data responsive to the distance between the listening position and the virtual sound source, and an effect sound generation section 17 for selecting any coefficient data in response to the distance data between the listening position and the virtual sound source and generating an effect sound signal obtained about an input sound source signal. According to the configuration, the move path of the virtual sound source moving through the virtual sound field space is specified, the distance to the listening position of the listener is sequentially calculated, and the effective sound signal based on a predetermined distance coefficient is continuously generated from the sound source signal.
