Inventor: SEKIGUCHI YOSHINOBU
IPC: H01L27/15
Filed: 1989-10-13
Abstract: PURPOSE:To make possible efficient laser oscillation and efficient modulation by a method wherein an active layer and a light guide layer of a multiple quantum well structure are formed sandwiching an isolation layer between them, a laser oscillation part and a modulation part are arranged sandwiching an isolation groove between them and electrodes, which respectively make an independent drive possible to the laser oscillation part and the light guide layer, are provided. CONSTITUTION:A semiconductor laser is constituted into a structure, in which a buffer layer 3 and a clad layer 4 are formed on a substrate 2 with a common electrode 1 mounted on its lower surface and moreover, a laser oscillation part 20 and a modulation part 30 are arranged on the layer 4, sandwiching an isolation groove 12 between the parts 20 and 30 in the propagation direction of light. Accordingly, P-type ohmic electrodes 10 and 11, which respectively can do an independent drive of the parts 20 and 30, are further respectively provided on each cap layer 9 of the parts 20 and 30. As an active layer 7, in which laser oscillation takes place, and a light guide layer 5, in which modulation is performed, are isolated by an isolation layer 6, it becomes possible to form the layer 7 thin and the layer 5 thick. Thereby, a high modulation degree can be obtained at a low oscillation threshold value.

Title: Ultrasonic probe
Inventor: MARUYAMA HIDEO
IPC: G01N29/24
Filed: 1984-12-17
Abstract: PURPOSE:To detect an internal defect at a high accuracy, by transmitting an ultrasonic wave to a thick metal plate through a columnal ultrasonic wave delaying member from a disc-shaped ultrasonic wave transmitting means to receive the reflected wave thereof by a ring-shaped ultrasonic wave receiving means through a cylindrical ultrasonic wave delaying member which is circumscribed and separated acoustically. CONSTITUTION:An ultrasonic wave being transmitted from a transmission vibrator 34 as disc-shaped ultrasonic wave transmission means is made to propagate through a transmission delay wire 38 as a columnal ultrasonic wave delaying member to be transmitted to a thick steel plate 10 to be inspected. The ultrasonic wave transmitted to the steel plate 10 produces a defect echo 20 due to an internal defect 16 of the steel plate 10. The echo 20 and other ultrasonic echoes propagates through a reception delay wire 40 as cylindrical delaying member and is received by a receiving vibrator 36 as ring-sheped ultrasonic wave receiving means. A cylindrical sound splitting member 42 is arranged to be separated acoustically from the delay wire 38 and 40. In this manner, internal defects can be detected at a high accuracy without the use o a short-range sound field on the steel plate 10.

IPC: F22G5/12
Filed: 1993-10-26
Abstract: PURPOSE:To improve a load changing speed without lowering a plant efficiency in a wide using range of a reheated steam temperature in a reheater. CONSTITUTION:Two fluids of boiler supply water from a tube 15 in a steam flow in a reheater 7 and high-pressure superheat steam from a tube 18 bled from a superheater 5 are sprayed to a reheater superheat reducing unit 17 to control reheat steam temperature. An atomizing nozzle employs a two-fluid atomizing structure, can remarkably finely atomize spray water as compared with the case of a conventional pressure atomizing type nozzle and stably finely atomize spray water even in a low steam flow rate operating range. Since it is intermittently used by limiting to the time of load change or emergency and can finely atomize with small thermal stress to a steam tube, reheated steam temperature control corresponding to a high speed load change is performed without problem of a decrease in a plant efficiency.
