Filed: 1989-03-20
Abstract: PURPOSE:To obtain the optical semiconductor device which decreases the light absorption at the time of impression of an electric field and with which a large on/off ratio is obtd. by using quantum wells having a strain in the quantum well of (i) layer of a pin structure semiconductor. CONSTITUTION:The (i) layer of the quantum wells 13 having strains is used as the pin layer 12 of the optical semiconductor device which has the pin structure semiconductor layer 12 having the (i) layer consisting of the quantum wells, impresses a prescribed electric field to the pin structure semiconductor layer 12 and absorbs the incident light on the pin structure semiconductor 12 by the quantum wells to generate the photocurrent and to change the voltage impressed to the pin structure semiconductor layer. The band structure in the semiconductor changes in this way and the band end of heavy holes and the band end of light holes part largely from each other. The absorption relating to the light holes does not longer contribute to the absorption relating to the heavy holes. As a result, the absorption at the time of the electric field impression decreases and, therefore, the absorption at the time of an decreases. The optical semiconductor device having a large on/off ratio is obtd.

Filed: 1994-04-06
Abstract: PURPOSE:To obtain excellent bending characteristics and flat crushing strength by a method wherein reinforcing fibers are employed respectively for the outermost, middle and innermost layers under the condition that the ratios of the thicknesses of the outermost, middle and innermost layers to the wall thickness of cylindrical body are specified, and the reinforcing fiber employed for the outermost layer has the compressive strength at least of a specified value, that employed for the middle layer has the compressive strength and modulus of tensile elasticity at least of a specified values and that employed for the innermost layer has the modulus of tensile elasticity at least of a specified value. CONSTITUTION:A cylindrical body consists of the outermost, middle and innermost layers, in which reinforcing fibers are arranged normal, axial and normal to its cylindrical axis in the order named. For the outermost layer, reinforcing fiber having the compressive strength of 100kgf/mm<2> or higher is employed for flat crushing strength. For the middle layer, reinforcing fiber having the compressive strength of 80kgf/mm<2> or higher and the modulus of tensile elasticity of 50,000kgf/mm<2> or higher is employed for improving bending characteristics. For the inner most layer, reinforcing fiber having the modulus of tensile elasticity of 50,000kgf/ mm<2> or higher is employed for obtaining dynamic balance as a whole. The ratios of the thicknesses of the respective layers to the wall thickness of the cylindrical body are set to be 12-20% for the outermost layer, 74-85% for the middle layer and 10-20% for the innermost layer for optimizing bending, flat crushing strength and modulus of flexural elasticity, because the too much thin outermost layer brings the lowering of the flat crushing strength, the too much thin middle layer brings the lowering of the modulus of flexural elasticity and even either thin one of the layers brings the bending strength.

CONSTITUTION:A subtraction counter 18 performs subtraction in synchronous relation to the subtraction clock from an AND circuit 28 from a value equal to the content of a previously loaded addition subtraction counter 16 and, when the content of the counter comes to zero, a borrow-signal is generated. This borrow-sigal is supplied to CRT32 through a signal amplifier 30 and, at the same time, a sweep signal is generated from a sweep signal generator 34 by the sweep gate signal from a terminal B to be applied to a deflection coil 36. Therefore, the display of a variable distance mark is performed on the sweep line of PPI in synchronous relation to said sweep operation. When the variable distance mark is displayed only on an electronic cursor at this time, the subtraction clock signal supplied to the addition subtraction counter 16 is at first a low speed and subsequently changed over to a high speed.
