    Abstract: A meter such as a speedometer for use in an automobile instrument panel includes a pointer driven by a stepping motor. A pulse voltage having a wider pulse width is supplied to the stepping motor to obtain a higher induced voltage to be compared with a threshold voltage for detecting the pointer-zero-position. After the pointer-zero-position is detected, the stepping motor is driven by a pulse voltage having a narrower pulse width to obtain a quicker response of the pointer. In this manner, the pointer-zero-position is accurately adjusted without sacrificing the quick response of the meter pointer.

    Abstract: A plurality of optical guide paths are built in a guide path plate. A plurality of optical guide posts are erected on the guide path plate so that each may oppose to one end of the corresponding optical guide path. The other end of at least one of the optical guide paths is optically connected to a light projecting portion, and the other end of at least another of the optical guide paths is optically connected to a light receiving portion. A part to-be-sensed which is movable is located between the distal ends of the optical guide posts whose base ends are connected to the corresponding optical guide paths. The presence of the part to-be-sensed is detected in such a way that the part to-be-sensed interrupts or transmits light which passes between the distal ends of the optical guide posts.

    Abstract: A photo detecting device comprises a photo-electron generating body, which absorbs light and generates photo-electrons, and a transistor, across which an electric current flows in accordance with a quantity of the photo-electrons having been generated by the photo-electron generating body. An electrical insulator is formed on a surface of the photo-electron generating body. The transistor is provided with a source electrode and a drain electrode, which are formed on the electrical insulator having been formed on the surface of the photo-electron generating body. The source electrode and the drain electrode of the transistor are connected with each other via a channel section containing a nano-tube having electrically conductive or semi-conductive characteristics.
