Title: Semiconductor light emitting element and fabrication method thereof
Inventor: HOTTA HITOSHI
IPC: H01S5/227
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To limit a driving current by including a region of Al compound where a second conductivity type clad layer has a specified compositional ratio of Al atom or above thereby decreasing the electrical resistance or thermal resistance of a semicon ductor diode or a light emitting diode and suppressing generation of heat. SOLUTION: A first conductivity type clad layer 4, an active layer 6, and a second conductivity type clad layer 8 are formed on a substrate 1 wherein the second conductivity type clad layer 8 is formed partially into mesa shape and the remaining thin part forms a current block layer 12. Al composition of the second conductivity type clad layer 8 is set higher than 30% of total compositional elements and since the Al composition is high, refractive index is decreased for the active layer 6 and the band gap is increased. Since the second conductivity type clad layer 8 exhibits a light confining function as a clad layer and a carrier confining function, a semiconductor laser oscillating with low threshold level and exhibiting good coupling of light and carrier can be realized.  Al composition of the first conductivity type clad layer 4 is not required to exceed 30% of total compositional elements but the composition is selected to have a band gap larger than that of the active layer 6 and a refractive index lower than that of the active layer 6.

Abstract: PROBLEM TO BE SOLVED: To improve the energy efficiency of heat-treatment by ultraviolet irradiation of a polycrystal semiconductor thin film by forming an anti-reflective coating having ultraviolet transparency and reducing the reflectance on the polycrystal semiconductor thin film, and irradiating the polycrystal semiconductor thin film with ultraviolet light through this anti-reflective coating. SOLUTION: A polycrystal Si thin film 2 is formed on a quartz substrate 1. Next, after Si ions are implanted into the polycrstal Si thin film 2 to make the polycrystal Si thin film 2 amorphous, boron (B) ions are implanted, thus forming a boron-doped amorphous Si thin film 3. Next, annealing is carried out in a nitrogen atmosphere, thus forming a p-type polycrystal Si thin film 4 having a large crystal grain size. Next, after a SiO2 film 5 having a thickness of approximately 500 Å is formed on the polycrystal Si thin film 4, the polycrystal Si thin film 4 is irradiated with a pulse laser beam 6 through the SiO2 film 5. In this case, the reflectance of the polycrystal Si thin film 4 having the SiO2 film 5 formed thereon is reduced greatly by approximately 25.5%.

Abstract: PURPOSE:To stabilize a developer supplying amount to a developing device by controlling the action of a supplying means so that developer supplying ability may be enhanced with the lapse of actuating time. CONSTITUTION:The specified toner supplying amount is maintained in spite of the lowering of fluidity by controlling the rotating action of a toner supplying brush 8 so that the toner supplying ability by the brush 8 may be enhanced with the lapse of the actuating time of a stirring member 3 after a toner hopper 1 is replenished with toner by a cartridge. Therefore, a measuring means for measuring the actuating time of the member 3 after the toner hopper 1 is replenished with the toner by the cartridge is provided, and the rotating speed is switched so that the rotating speed of the brush 8 is increased in accordance with the measured result by the measuring means. In such a case, the rotating speed of the brush 8 is set high, but it is conceivable that the rotating time of the brush 8 at the time of performing toner supplying action once is made longer.

Inventor: IWAKI TAKESHI
IPC: G10L13/06
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a high-quality synthetic voice by providing an element piece producing method which has both merits of an one pitch-equivalent waveform element piece producing method and a symmetrized element piece producing method while limiting a processing quantity and a holding information quantity to slight increase as compared with the conventional symmetrized element piece producing method and in which connections are satisfactory and the degrading of higher harmonic components is small.

Abstract: PROBLEM TO BE SOLVED: To provide a power feeding termination device for a load that can prevent the occurrence of a situation to disable the power feeding to a load from being terminated when a wire is broken in a circuit containing a switch while using a normally opened switch. SOLUTION: A brake sensor 42 has electrodes 44a, 44b opposite to each other and electrodes 44c, 44d opposite to each other. When the brake sensor 42 is operated while an electric motor 20 is in operation, a current is carried to a coil 26a of a hold release relay so that its contact 26b is opened. Thereby, the current carried to a coil 24a of a hold relay is stopped so that its contact 24b is opened. As a result, the current carried to the coil 22a of a starting relay is stopped so that its contact 22d is opened and thus, the operation of the electric motor 20 is stopped. In case that a wire is broken in a self-holding circuit 34, the current to the coil 24a of the hold relay is stopped and the operation of the electric motor 20 is stopped as well.

Abstract: PURPOSE:To precisely detect a peak value by comparing the maximum value at the finishing time of high-speed searching action with a reference value which is previously set and setting a level when a music signal is recorded. CONSTITUTION:The music signal recorded on a disk 1 is sampled and reproduced by a searching action control means 4 and the peak value thereof is detected by a signal processing means 3. Besides, the maximum value of the peak value of every sampling is stored in the first and second peak value storage means 5 and 6 and the average value thereof is calculated by a peak average value calculation means 8. Then, the peak level for setting a recording level is detected. Therefore, the optimum peak level for setting the recording level can be detected. Besides, a peak value storage control means 7 is provided. Then, when a signal read error occurs, the peak value which is not affected by the signal of a large level generated when the error occurs is detected by compensating a peak data value. Thus, the recording level is set by precisely detecting the peak value.

IPC: G08G1/16
Filed: 1991-09-13
Abstract: PURPOSE:To surely prevent the vehicle collision due to suddenly meeting at an intersection and to quickly report the device malfunction due to a severe environmental condition, noise, or the like. CONSTITUTION:When vehicles simultaneously approach the intersection from one and the other roads, approaching object detectors 1 and 2 detect distances to the intersection and velocities of vehicles.
