Title: Semiconductor laser
Inventor: UEKI ATSUSHI
IPC: H01S5/00
Filed: 1978-05-18
Abstract: PURPOSE: To ensure the steady oscillation by forming one of the reflecting surfaces with the dielectric multi-layer film and providing the property to the reflection factor to prevent variation of the oscillation wavelength caused by the temperature.  
     CONSTITUTION: Dielectric multi-layer film 11 and SiO 2  thin film 15 are evaporated on cleavage surface 3 and 4 of the GaAs doublehetero laser element, sealed to heat sink 21 of Si and then fixed to copper mount 31. Thus, element 1 can be prevented from being at a high temperature and hard to oscillate. For the GaAs laser, the gain maximum wavelength becomes long as the temperature increases, and thus the gain generally lowers down. In this constitution, one of the reflecting surfaces is formed with the dielectric multi-layer film featuring the temperature dependence property, and thus the temperature dependence can be controlled for the oscillation wavelength by changing the material, the number, the structure and others of the multi- layer film and then altering the wavelength dependency of the reflection factor for the multi-layer film. As a result, a miniature and easy-manufacture semiconductor laser can be obtained as conventional with a high mechanical stability, also reducing the variation of the oscillation wavelength caused by the temperature.

Title: Automatic focusing device
Inventor: KUNO TETSUYA
IPC: H04N5/232
Filed: 1991-03-26
Abstract: PURPOSE:To attain focusing with high focus accuracy and at high focusing speed by changing an amplification gain of an amplifier circuit depending on the focus evaluation value. CONSTITUTION:When an object has a low contrast, a focus evaluation value outputted from an integration device 9 is decreased. Then a control circuit 10 outputs a control signal to an amplifier circuit 5 to increase the amplification gain of the amplifier circuit 5. As a result, a maximum value of the focus evaluation outputted from the integration device 9 is detected to attain focusing. Simultaneously, the control circuit 10 controls a motor driver 11 so as to maximize the focus evaluation value obtained from the integration device 9 thereby driving a focus motor 12 to attain focusing. Thus, the focusing with high focusing accuracy and fast speed is attained without repeating the focusing due to undetection of the focal point like a conventional automatic focus device.
