Title: Objective lens moving amount detector for optical pickup
Inventor: MIYAIRI NOBUO
IPC: G11B7/09
Filed: 1988-09-14
Abstract: PURPOSE:To prevent the life of a light emitting element from being shortened as far as possible, and to improve the sensitivity of a position sensor by providing a driving means to execute intermittent light emission and a detecting means to generate an objective lens position signal. CONSTITUTION:When the moving amount of an optical pickup is detected, an oscillator 3 oscillates a switching signal, and intermittently drives a light emitting element 1 through a driver 2. Together with the movement of an objective lens 5, a shading plate 6 forms shade on a photodetector 4 consisting of two photodiodes PD1 and PD2. At a time, t1, the shade is in a neutral condition, and a differential amplifier 4 is not outputted. According to the movement of the shade of the plate 6 from a time t2 to t3, the output of the PD1 is decreased, and the amplifier 4 generates the subtracted output according to the deviation of the both outputs. In such a case, since the PD1 and PD2 output the signals only at the time of the light emission of the element 1, the output of the amplifier 4 also becomes the intermittent output. However, since the output passes through a sample-hold circuit 8, the moving information signal of the lens 5 is obtained. Here, the element 1 maintains durability even when a current increases.

Filed: 1987-09-14
Abstract: PURPOSE:To clamp a tool of small size by securing an internal surface electrode, whose internal diameter is somewhat smaller than the diameter of a shaft part of the small-sized tool, to the internal peripheral surface of a cylindrical piezoelectric element and an external surface electrode to the peripheral surface of the piezoelectric element and applying voltage between the internal and external surface electrodes. CONSTITUTION:Forming an internal diameter of an internal surface electrode 2 slightly smaller than the diameter of a shaft part of a small-sized tool 9, a slit 4 in the axial direction is provided in the internal and external electrodes 2, 3. A voltage connector 7 is brought into contact with conductor pins 5a, 5b, and when voltage is applied between the internal surface electrode 2 and the external surface electrode 3, piezoelectric elements 1a, 1b spread in the radial direction, enabling the shaft part of the small-sized tool 9 to be inserted. When the voltage connector 7 is separated from the conductor pins 5a, 5b, because the piezoelectric elements 1a, 1b tend to contract to the original size, the shaft part of the small-sized tool 9 can be clamped. Since this clamping device eliminates the necessity for forming the rotary part in double construction, manufacture is facilitated.

Abstract: PROBLEM TO BE SOLVED: To display without reversing a display image over the whole surface of a liquid crystal panel, by comprising a driving means for driving an electro- optical device so that an image is not reversed in the vertical or horizontal direction. SOLUTION: A shift register of a scanning line driver 112 for sequentially supplying a scanning potential and sequentially scanning scanning lines is shifted in the vertical direction, and a shift register of a signal line driver 113 for supplying signal lines with signal potentials corresponding to image data of each pixel is shifted in the horizontal direction.
