Abstract: A driving assistance device enables a driver who manually performs an accelerator operation and a steering operation to easily retain an accelerator operation state in a constant state. A driving assistance device includes a manually operable accelerator operation unit in the vicinity of a steering wheel provided in front of a driver seat in a vehicle cabin. The accelerator operation unit is operable in a state where the steering wheel is gripped and an operation reaction force of the accelerator operation unit exhibits an inflection point POI at which the operation reaction force rapidly becomes large in response to an increase in an operation amount of the accelerator operation unit.

Abstract: A disclosed information processing apparatus is equipped with a built-in display unit and a built-in input unit. A display signal supplied from an external information processing apparatus connected to the information processing apparatus is combined with a display signal supplied from a core processing unit in a part of a screen of the display unit displaying the signal supplied from the core processing unit. An input signal received from the input unit is output only to the external information processing apparatus or only to the information processing apparatus depending on whether the part is determined as being activated or inactivated.

Abstract: A starting method of an electronic apparatus wherein power supplies of a plurality of the electronic apparatuses are started in order, the starting method includes the steps of resetting the electronic apparatuses when each of the electronic apparatuses is started; and canceling the resets of the electronic apparatuses at the substantially same time after a power supply started last among power supplies of the plural electronic apparatuses is started.

Abstract: A quantitative echo sounder includes delay circuits, phase correction circuits, an incidence angle calculator and a directivity correction unit. The delay circuits adjust transmission start timing or phases of acoustic waves radiated by individual vibrating elements based on pitch and roll angles measured by a motion sensing device so that the direction of an acoustic axis of a transmitting beam matches a sounding direction. The phase correction circuits adjust phases of received echo signals based on the pitch and roll angles so that the direction of an acoustic axis of a receiving beam matches the sounding direction. The incidence angle calculator calculates echo signal incidence angle with respect to the sounding direction from phase differences among receiving beam signals obtained by four vibrating element groups. The directivity correction unit corrects a measured target strength by using the echo signal incidence angle calculated by the incidence angle calculator.

Abstract: The invention provides a trackball unit featuring good water resistance and user maintenance capabilities. A case (3) of the trackball unit has a drain pipe (32) connecting a cavity (33) formed inside the case (3) for accommodating a ball (2) to the exterior of the case (3). A case cover (6) has a ring-shaped projecting part (62) while a ball cover (7) has a pair of locking tabs (72, 73) which engage with the projecting part (62) of the case cover (6), so that the ball cover (7) can be detachably fitted to the case cover (6).

Abstract: A portable electronic terminal apparatus includes a main body, an information input mechanism, a plurality of displays, a communications mechanism, and a flip panel. The main body has a hollow section. The information input mechanism inputs various kinds of information including data and instructions. Each of the displays shows the various kinds of information input through the input mechanism. The communications mechanism transmits and receives the various kinds of information input through the input mechanism. The flip panel is movably mounted on the main body and is configured to rotate to open and close about a side edge portion of the flip panel. This flip panel is retracted in the hollow section of the main body when the flip panel is closed. In addition, one of the displays is mounted on the flip panel.

Abstract: An open/close type connector having a base member, a cover member, and an electronic apparatus of a card type or a personal computer type using the connector. The connector is thin so that when it is not used, i.e., is not connected with a modular plug the portability of the card is not lost. In addition, less restriction is introduced on the attachment position at which the connector is attached to the card or the personal computer. A link is used for opening and closing the cover member. Structure for enhancing the stability and the electrical connection reliability when a modular plug is mounted on the connector is provided, and the base member and the cover member are adapted to be rotatable so that they can be relatively opened or closed thereby yielding a connector which can be preferably adopted by an electronic apparatus of a card type.
