IPC: H01S5/223
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser element which is easy to manufacture having low noise characteristics, and to provide its manufacturing method. SOLUTION: A semiconductor laser element 100 includes an AlGaN buffer layer 2, a GaN layer 3, an n-GaN layer 4, an n-AlGaN layer 5, an MQW light emitting layer 6, a p-clad layer 7, and a p-first GaN cap layer 8, an n-AlGaN current block layer 9, and a p-second GaN cap layer 10 sequentially laminated on a sapphire substrate 1. In an etching step, a ridge part having an upper face with a width of W1 is formed. The current block layer 9 has an opening with a width W2 on an upper face of the ridge part. Since the width of W2 of the opening is smaller than the width of W1 of the upper face of the ridge part, a saturable absorption region 20 formed on both sides of a current injection region is obtained in a light emitting region 21 of the MQW light emitting layer 6.

Abstract: PURPOSE:To use the subject device for common use of transmit-receive without changing the space disposition of one convolver by dispersing a compression waveform signal to be written into a storage means, reading them in reverse order of a write address to be transmitted out. CONSTITUTION:Prior to transmission, a pulse of the compression waveform oscillated by a program pulse generator (PPG) 11 is inputted into the convolver 12 to be converted into a dispersing waveform, and converted via a receiving amplifier 13 and a comparator 14 into a digital signal, and then stored in descending order of the write address into a storage device 15. Then, at the time of transmitting, an MV 17 is started up by a pulse of a trigger pulse generator 3 to generate a read address to an address scanner 16. At that time, data stored in the device 15 are read out by this read address in ascending order and turned into a dispersing waveform signal to be sent out from a transducer 6. Then, a received reflected wave is passed through the convolver 12 in the same direction as the pulse generated by the PPG 11, so as to be restored to the same pulse as the pulse generated by the PPG 11.

IPC: B01D21/01
Filed: 1993-04-06
Abstract: PURPOSE:To prepare a waste water treatment agent which can remove a nonionic surface active agent effectively and set the level of waste water after being treated to be dischargeable by incorporating a refined novolac resin from which impurities are removed by the water elution containing alkaline substance and an alkaline substance into the agent. CONSTITUTION:A refined novolac resin formed by removing impurities by means of the water elution containing alkaline substance and an alkaline substance are contained in the waste water treatment agent. In the waste water treatment using the waste water treatment agent, the alkaline substance is used combinedly to dissolve the novolac resin into waste water, and then an acidic substance is added thereto to pick up and precipitate the nonionic surface active agent in the waste water. The waste water can be separated into supernatant liquid and precipitated substance by the arrangement, and the waste water can be treated by removing the precipitated substance. The supernatant liquid is transparent and scarcely contains novolac resin-originated impurites, to say nothing of dry solids.

IPC: G10H1/00
Filed: 1989-03-30
Abstract: PURPOSE:To produce sounds of more variable kinds even to one piece of music by providing plural operators, plural memories respectively corresponding to the plural operators, and means which selectively switches a program mode to a play mode, or vice versa. CONSTITUTION:When an assigned program mode is set by means of a program operator 14, arbitrary ones of produceable sounds of percussion instruments are assigned to pad operators 11a-11d time sequentially and, at the same time, sound information expressing the assigned sounds is successively stored in memories respectively corresponding to the operators. Moreover, when a play mode is set by a play operator 13, the sound information stored in the memories corresponding to the operators is successively read out and outputted at every operation of each operator and produced as sound signals. Since different sound information is stored in the memory corresponding to one operator time sequentially, different sound signals can be produced even when only one operator is successively operated.

Title: Cathode-ray tube
Inventor: NATORI TAKEHISA
IPC: H01J29/86
Filed: 1989-03-30
Abstract: PURPOSE:To increase the brightness of a cathode-ray tube and shorten the min. visible distance by installing a grating plate having photo-reflective surface within a front panel, wherein the grating plate has windows each of which is mating with a fluorescent substance trio. CONSTITUTION:A grating plate 10 having photo-reflective surface, equipped with a window 16 mating with each fluorescent substance trio 4, is installed within a front panel 2. Lights emitted from fluorescent substance layers B, R, G are total-reflected by this grating plate 10 and cast out regardless of its angle of emission. This enables enhancement of the brightness of a cathode- ray tube A. Because one window 16 is provided for each trio 4, lights from the fluorescent substance layers B, R, G are cast out as a light mixed in the window 16. Accordingly the resolution of a resultant image will be substantially the same as the resolution viewed at a comparatively long distance. This will shorten the minimum visible distance.

Abstract: PURPOSE:To prevent oil leak even in partial load operation by always pressing a seal ring onto the side-wall surface of an annular groove formed on a rotary shaft by the compressed air which is introduced into one side of the seal ring. CONSTITUTION:Since the pressure in a slit 15 is inceased in comparison with the pressure in a slit 11 by the compressed air introduced through a conduit 14 in a rotary shaft 2, a seal ring 1 is compulsorily pressed onto the wall 20 on a low- pressure side of an annular groove 3 on a shaft 2, independently of rated operation and partial-load operation. Further, leak of the compressed air introduced into the right-side slit 15 of the seal ring 1 can be prevented by a labyrinth 17.

Filed: 1987-03-31
Abstract: PURPOSE:To operate a high output in a stable basic lateral mode by so forming a groove as not to pass a current blocking layer in a region near a laser light emitting end face but as to pass it at the other region. CONSTITUTION:A groove 3 does not pass a current blocking layer 5 in a window region 10 near a laser light emitting end face so that a current is not injected to the active layer 5, but pass it in other oscillation region 20 so that a current is injected to the layer 5. Thus, a lateral mode unstable in the bent region of the layer 5 is controlled by passing the region 10, and a stable basic lateral mode oscillation is performed. The layer 5 is flat and thin at the region 10, but bent in a recess state and thick to reflect the shape of the groove 3, the whole region is formed under the same growing conditions, and manufacturing steps are not complicated.

IPC: G01L1/24
Filed: 1985-04-16
Abstract: PURPOSE:To improve an S/N by utilizing effectively light, by providing a means for separating the light by a mode propagating through the inside of an optical fiber. CONSTITUTION:Light from a light source 1 propagate through an optical fiber 2, and goes into a photodetector 3m1 through a separating and photodetecting part 6 which exists between a pressure plate 5 and a photodetector 3 (3s1-3m1) and separates the light by a mode. A signal detected by the photodetector 3m1 is an output of a core mode, and a signal detected by the photodetector 3s1 is an output of an optical component being a clad mode in case no jacket in this part is removed, and a radiation mode. In this state, by adding the output of the photodetector 3m1 and the output of the photodetector 3s1 in an equal ratio by an adder 18, a reference optical signal containing a variation element of the light source 1 is obtained without being influenced by a microbend at all. A signal optical output 16 of the photodetector 3m1 can compensate an output variation of the light source 1 by deriving a ratio of the signal optical output 16 and a reference optical output 15 by a divider 17.
