Title: High-output semiconductor laser
Inventor: KAMESHIMA YASUBUMI
IPC: H01S5/00
Filed: 1985-08-26
Abstract: PURPOSE:To improve yield, and to obtain a high output by using multilayer quantum well structure constituted of a semiconductor thin-film as an active layer,isolating a current constriction section for the active layer from a cleavage end surface through Zn diffusion and composing the current constriction section of a region in which multilayer quantum well structure is changed into a mixed crystal. CONSTITUTION:An SiO2 film 6 with a striped window for constricting currents is formed onto a P<+> type Al0.1Ga0.9As cap layer 5, but the film 6 is 10mum wide and is isolated at every 5mum from both cleavage end surfaces. When Zn is diffused from an opening section 7 isolated from the end surfaces,a superlattice is changed into a mixed crystal when diffused Zn reaches the layer of the GaAs/ Al0.1Ga0.9As superlattice. Consequently, n active layer is turned finally into the uniform mixed crystal 8 consisting of Al0.05Ga0.95As only under the opening section 7 of the SiO2 film. A section converted into the mixed crystal constitutes a section corresponding to the opening section 7, a current constriction section (a current injecting section).

Abstract: PURPOSE:To enable an efficiency of a boiler to be increased by a method wherein a flow rate regulating means to be operated in response to a temperature of inner fluid of a primary air preheater and a temperature of combustion gas discharged from the primary air preheater is arranged in a bypass passage. CONSTITUTION:A part of air supplied from a pressure fan 1 is morged with hot air in a hot air system 6 through a bypass passage 12 and a bypass air flow rate adjusting damper 13. The flow rate regulting damper 13 is controlled by a controller 16 receiving each of the sensed signals from a thermometer 14 for sensing a temperature of the inner fluid in the primary preheater 3 and a thermometer 15 for sensing a temperature of the combustion gas discharged from primary air preheater 13. Thus, air bypass volume is controlled in such away that a metal temperature at a low temperature part of the primary air of the primary air preheater 3 or a temperature of the combustion gas can have a required value in response to a mixing and combustion ratio between coal and heavy oil. For example, when coal only is fired, it is possible to decrease a temperature of combustion gas to about 100 deg.C or so while a metal temperature at a low temperature part of the primary air preheater is kept at about 90 deg.C for a dew point of acid of 50-80 deg.C. Therefore, it is possible to increase an efficiency of boiler accordingly.

Title: Integrated circuit device
Inventor: YAMADA KOICHI
IPC: H01L21/822
Filed: 1990-07-16
Abstract: PURPOSE:To reduce the frequency at a neck area by grasping previously a control signal at a point where the signal transmission delay is large. CONSTITUTION:The clock inputs 1 are inputted from the outside of an LSI and supplied to plural internal clock drivers 2 of the LSI. The driver 2 usually serves as a normal buffer and therefore a waveform equal to that of the input 1 is obtained. The outputs of the drivers 2 are supplied to plural dividing circuits 3 which are controlled by the input of a dividing ratio control circuit 4. That is, the timing with which the neck of the internal signal transmission delay is generated by the output of the circuit 3 when the input of the circuit 4 is set at a high level. Thus it is possible to ensure an operation as if the 1/2 frequency were set although the same frequency is used from the outside og the LSI by delaying only a relevant area by a prescribed period. In other words, the neck is substantially eliminated despite the delay needed.
