IPC: H01S5/00
Filed: 1988-03-25
Abstract: PURPOSE:To increase variable tuning width and channel number by providing phase control regions which are disposed on both sides of a distribution feedback region, are optically coupled to this region and are capable of controlling the end face phase of said region from the outside. CONSTITUTION:A diffraction grating is formed in the distribution feedback region 100 of an n-InP substrate 110. An InGaAs light guide layer 120, an n-InP buffer layer 130, an active layer 140, and a p-InP clad layer 150 are successively formed thereon. After the layers 150, 140 of the phase control regions 200, 210 are selectively removed, an InP clad layer 160 is formed over the entire part. This filter is made into a flush structure for the purposes of carrier confinement and transverse mode control. Electrodes 300, 310 are formed to the substrate side and the growth layer side and grooves are formed by removing the neighborhood of the mesa at the center. A transmission wavelength moves continuously to a short wavelength side when current I1 is injected to the region 200. The transmission wave moves further to the short wavelength side when current I2 is injected in this state to the region 210.

IPC: G10H1/057
Filed: 1988-03-26
Abstract: PURPOSE:To enable easy setting of the various intensity of the sounds of sound sources with each other by adding the sound volume data for each of notes to envelope data and prohibiting the data to be added if the envelope data is soundless.

Title: Fluidized layer equipment
Inventor: ITOU KANICHI
IPC: F28D13/00
Filed: 1979-06-09
Abstract: PURPOSE: To reduce the wear of heat transfer tubes immersed in a fluidized layer, by disposing the parts of the heat transfer tubes, in paralllel with the flow of fluidizing gas and using a material of high wear resistance for the surface of the unimmersed part of each tube.  
     CONSTITUTION: The headers 8, 9 of a heat exchanger are coupled to each other by heat transfer tubes 7 and immersed in a fluidized layer 1. The heat transfer tubes are disposed in parallel with the flow 11 of fluidizing gas. Since the headers 8, 9 extend across the fluidizing gas flow 11, the headers are coated with such a material 10 of high wear resistance as a wear-resisting metal, ceramic or the like. As a result, the wear-resisting lifetime of the headers 8, 9 is greatly lengthened even if heat medium grains straightly collide against the headers or the vortexes of the grains collide against the rears of the headers.

Abstract: PURPOSE:To relatively change a light quantity ratio of blue light emission to red light emission, and change a color of a single lamp over a wide range by mainly adjusting a duty ratio of a pulse when ultraviloet rays generated by discharge are converted into visible radiation. CONSTITUTION:In a fluorescent lamp in which low pressure mercury vapor and inert gas are sealed, a spectrum composed of emitting light of a mercury wire and a phosphor in a visible area is changed by using a phenomenon that a mercury ray strength ratio in an ultraviolet and visible area changes by depending on a pluse lighting condition of this fluorescent lamp. It is preferable to provide at least a single kind of red phosphor having an initial emitting light attenuation time constant not less than 1000 times to a time donstant approximate to 1/e of initial attenuation of the mercury wire to emit light in a blue area. When pulse lighting is performed on this fluorescent lamp, a duty ratio expressed by a percentage of a value obtained by dividing a pulse width by a cycle period is largely adjusted, and a ratio value is changed, and a color of a single lamp is changed.

Abstract: PURPOSE: To widen the effective control area of the spool of a direction-switching valve, by a method wherein, in a direction-switching valve with pressure compensation, a discharge pressure fluid in a pressure fluid source is all discharged into a tank through a pressure compensate valve when the direction-switching valve is situated in a neutral position.  
     CONSTITUTION: A pressure compensate valve 4 and a valve 5 are mounted between a direction-switching valve 2 and a pressure fluid source 3. When the direction- switching valve 2 is positioned at neutral, both a toroidal channel 28 in the direction-switching 2 and a feed path 21 are closed, and thereby a pressure fluid begins to be increased in pressure. A spring chamber 53 of the pressure compensate valve 4 is then connected to a tank through a pilot path 40, and a pressure chamber 52 is coupled to a line 17 through a pilot path 55 and the valve 5 to exert a pressure. This causes the rightward movement of a spool 49 to couple together a toroidal channel 42 and a toroidal channel 44, and the whole amount of the pressure fluid in the pressure fluid source 3 flows out to the tank.
