Abstract: As an antitumor drug which is excellent in terms of antitumor effect and safety, there is provided an antibody-drug conjugate in which an antitumor compound represented by the following formula is conjugated to an antibody via a linker having a structure represented by the following formula: -L1-L2-LP-NH—(CH2)n1-La-Lb-Lc- wherein the antibody is connected to the terminal of L1, and the antitumor compound is connected to the terminal of Lc with the nitrogen atom of the amino group at position 1 as a connecting position.

Abstract: A mobile digital device comprises a ten-key pad being comprised of a key mat 21 on which ten-key buttons 21a-21c with respective projections 21aa-21cc on the under surfaces thereof are laid out and a key circuit board on which respective contacts 22a-22c corresponding to the projections are laid out, an electrostatic capacity sensing pad 30 for sensing an electrostatic capacity change to detect a touched region and having through holes to be inserted the projections corresponding thereto and being provided with between the key mat 21 and the key circuit board 22, and a controller for selecting a function corresponded to a feature of the touched region detected by the electrostatic capacity sensing pad and executing the selected function. Owing to such constructions, a desired function can be selected by way of finger touching to the mobile digital device.

Abstract: A control apparatus drives a motor to move a window glass to an opening end locking position beyond a preset stop position and thereby to forcefully stop the window glass at the opening end locking position when the control apparatus senses that an operational switch is continuously operated by a user for a predetermined time period or longer to perform the opening operation of the window glass based on an operational command signal outputted from the operational switch. The control apparatus then resets the preset stop position based on an actual stop position of the window glass at the opening end locking position in a preset stop position resetting operation.

Abstract: A microcomputer outputs a driving frequency signal to an oscillator circuit and the oscillator circuit oscillates at a driving frequency designated by the microcomputer. A switching control circuit outputs switching signals to an A-phase amplifier circuit and to a B-phase amplifier circuit at a predetermined timing. The A-phase amplifier circuit and the B-phase amplifier circuit each convert a DC voltage supplied by a voltage control circuit to an AC voltage and supply the same to two piezoelectric bodies of an ultrasonic motor. Due to the AC voltage being supplied to each of the two piezoelectric bodies, the ultrasonic motor is driven. At the start time of driving the ultrasonic motor, by gradually increasing the voltage level of the DC voltage outputted from the voltage control circuit and also gradually increasing the voltage level of a driving voltage to be supplied to the piezoelectric body of the ultrasonic motor, a stator and a rotor of the ultrasonic motor are gradually separated from each other.
