摘要:
A headlamp for a vehicle includes a light source adapted to emit a spotlight, a lens adapted to receive and transmit the spotlight, a lens actuator adapted to adjust a size of the spotlight transmitted through the lens, a two-dimensional optical deflector adapted to deflect the spotlight from the lens to an illumination area ahead of the vehicle, and a control circuit configured to control the lens actuator in such a way that irregularity of illumination in the illumination area is avoided.

A wafer-level optical deflector assembly is formed on a front surface side of a wafer. Then, the front surface side of the wafer is etched by using elements of the wafer-level optical deflector assembly, to form a front-side dicing street. Then, a transparent substrate with an inside cavity is adhered to the front surface side of the wafer. Then, a second etching mask is formed on a back surface side of the wafer. Then, the back surface side of the wafer is etched to create a back-side dicing street. Then, an adhesive sheet with a ring-shaped rim is adhered to the back surface side of the wafer. Then, the transparent substrate is removed. Finally, the ring-shaped rim is expanded to widen the front-side dicing street and the back-side dicing street to pick up optical deflectors one by one from the wafer.

A light scattering element 1 is equipped with a transparent, thin film-like optical element 2 which scatters incident laser light, and a thin film-like piezoelectric element 4, which is sandwiched between two electrodes 3a, 3b and which is laminated on a surface of the optical element 2 that is different from an optical scattering surface 2a. The light scattering element 1 averages a speckle pattern of laser light scatted by the optical scattering surface 2a and emitted therefrom by vibration of the piezoelectric element 4 generated when alternating voltage is applied between the two electrodes 3a, 3b.

A touchscreen panel input device is manufactured by forming a first adhesion layer and a second adhesion layer on a growth substrate, removing only the second adhesion layer from a selected region by irradiating laser, forming a growth base layer on the selected region where the second adhesion layer is removed and on the second adhesion layer and an oxide thin film having piezoelectricity on the growth base layer, transferring the oxide thin film layer on the selected region to a second substrate having first transparent electrodes by peeling-off, and adhering the second substrate to a third substrate having second transparent electrodes by placing the transferred oxide thin film layer between them. The touchscreen panel input device detects a pushing pressure in addition to a touch position with proving a tactile feedback.

摘要:
A driver for driving an optical deflector includes a mirror, a movable frame for supporting the mirror, a support body surrounding the movable frame, and a first group of piezoelectric actuators and a second group of piezoelectric actuators alternating with the first group of piezoelectric actuators. A first drive voltage for the first group of piezoelectric actuators has first repeated waves each with a first rising period. A second drive voltage for the second group of piezoelectric actuators has second repeated waves each with a second falling period corresponding to the first rising period of the first drive voltage and a second rising period corresponding to the first falling period of the first drive voltage. Frequencies of the first and second repeated waves exclude natural frequencies of a mechanically-vibrating system of the mirror with respect to the axis thereof depending upon the piezoelectric actuators.
