IPC: H01L31/109
Filed: 1978-07-17
Abstract: PURPOSE: To raise efficiency and reduce noise by making up the avalanche region and photo absorption region of different materials respectively.  
     CONSTITUTION: In the composite semiconductors comprising 2 to 4 elements, if they may be differed in their composition from the others, being very frequently coinsident with each other in their grid constant. An avalanche photo diode can be obtained when the materials having a similar grid constant may be used, the materials with a high gain and optimum for a low noise operation are selected for an avalanche region and the material having a highest quantum efficiency for the utilizing wavelengths is used for light absorption region. For example, type n -  or i InP9, P or P + -type In 0.53 Ga 0.47 As10 is laminated by continuous liquid phase epitaxial on a n + -type InP substrate 8 to make a hetero construction substrate. A circumfernce surrender is prevented with a mesa etching, the pn junction is reverse-biased by providing an electrode. In this device, because In 0.53 Ga 0.47 As are used for the light absorption region, the complete grid matching can be obtained and the light upto about 1.7μm be detected.

Abstract: PURPOSE:To prevent an image pickup tube from burning by outputting a focusing signal when the inclination of a simpled video signal exceeds a prescribed value, and on the basis of the signal, executing automatic focusing and iris control. CONSTITUTION:A CPU5 calculates luminance distribution on the basis of a video signal written in a memory 8 and compares the inclination of the luminance distribution with a prescribed value to detect a sharp changing point exceeding the prescribed value. When the CPU5 detects the most sharp changing point, the changing point is judged as a fucusing position, a focusing signal F is outputted from the CPU5 and a motor stopping signal is outputted from a motor control circuit 9 on the basis of the focusing signal F to stop a motor 10 for moving a focus lens 1a. When focusing is impossible on a range finding line fixed on one scanning line, a range finding line setting signal is changed to move the range finding line up and down in the vertical direction and a start position specifying signal S3 outputted from the CPU5 is changed to move a range finding area in the horizontal direction and execute focusing operation.

Title: Slot type optical fiber cable
Inventor: OKADA NAOKI
IPC: G02B6/44
Filed: 1995-03-17
Abstract: PURPOSE: To obtain a side pressure characteristic to allow the reduction of a rib thickness down to about 1mm and excellent impact characteristic and to reduce the diameter of a cable by specifying the Young's modulus of a slot rod material. CONSTITUTION: This single slot type optical fiber cable is formed by providing the outer periphery of a bar-shaped body with plural lines of grooves 52 capable of housing at least ten sheets of multiple fiber coated optical fiber ribbons and housing the coated optical fiber ribbons 10 in the respective grooves 52. The Young's modulus of the material of the slot rod 50 is specified to 60 to 120Kg/mm<2> . The reason why the Young' s modulus of the material of the slot rod 50 is specified to 60 to 120kg/mm<2> lies in that the ribs 54 formed the grooves 52 are liable to be deformed, the side pressure characteristics are degraded and transmission loss is liable to arise and eventually, the reduction of the outside diameter of the cable is not possible if the grooves 52 are formed at <60Kg/mm<2> .  The reason why the Young's modulus is specified to <=120Kg/mm<2> lies in that the ribs 54 are liable to be damaged by impact, etc., at a low temp. and the force to absorb impact force degrades and, therefore, the impact force is applied on the coated optical fiber fiber ribbons and the breakage of the coated optical fiber fiber ribbons arises if the value is exceeded.

Abstract: PURPOSE:To eliminate the need for any gas tank and make it possible to start the application of voltage after the pressure of the gas in a container has exceeded a prescribed value, by providing a heater inside or outside the container for heating a liquid in the container at the starting of the operation. CONSTITUTION:A container 3 is provided at its bottom with a heater 14a employing an electric resistance means. The heater is connected to a power source 16 through a switch 15. A controller 17 is connected to a pressure sensor 18 in the container. A pump 19 for spraying a cooling liquid 6 on a winding 1 and a core 2 is provided. At starting, the liquid 6 is preheated by the heater 14a, since a mixed gas 5 and the liquid 6 are low in temperature and hence the gas pressure and the dielectric strength are low. When the gas pressure exceeds a prescribed value, this is sensed by the sensor 18, and a voltage is applied to start. After the application of voltage, the temperature is raised by the heat generated from the winding 1, the core 2 and so forth, therefore, the pressure sensor 18 turns OFF the switch 15 through the controller 17 to cut the current supply to the heater.
