Abstract: A piezoelectric power generating device includes a power generating element and a package member. The power generating element includes a plate-like piezoelectric element and a metal plate. The piezoelectric element has a pair of principal surfaces opposite each other. The metal plate is bonded to one of the principal surfaces of the piezoelectric element. The package member has a supporting part and a restricting part. The supporting part supports an end of the power generating element in a cantilevered manner. The restricting part is disposed opposite the piezoelectric element with the metal plate interposed therebetween. The restricting part restricts displacement of the power generating element toward the outside of the metal plate.

Abstract: A USB storage device having the function of preventing stored software from being deleted by mistake achieved with as simple a structure as possible. In the USB storage device, the storage area is divided into an area in which execution of reading, writing and deleting is allowed and an area in which only execution of reading is allowed. Information to make a USB mass storage class driver recognize these areas as areas corresponding, respectively, to logical unit numbers defined in the SCSI command set of the USB mass storage class driver owned by the host is stored in the USB storage device. The information includes logical unit numbers, formats, writing/deleting allowed/not allowed flag, logical block numbers and physical block numbers. By this, the USB mass storage class driver recognizes the USB storage device as a SCSI device having two logical units.

Abstract: A proposed computer input device for transmitting the displacement data representing the quantity and direction of the movement of a cursor to a computer is operable in a narrow space and easily portable. The input device is provided with a pressure sensitive pad composed of a conductive layer formed on the underside of a flexible sheet and a resistor layer formed on the upper face of a substrate at a predetermined interval from the conductive layer. When the flexible sheet is depressed, the conductive layer contacts the resistor layer at the depressed position. In a control circuit connected to the conductive layer and the resistor layer, when the contact of the conductive layer with the resistor layer is detected, a voltage of 5V is applied alternately in a horizontal direction and a vertical direction on the surface of the resistor layer. The depressed position on the pressure sensitive pad is sequentially computed from the voltage value produced on the conductive layer when the voltage is applied.
