Title: Luminous phosphor, and luminous fluorescent powder, and their production
Inventor: UEHARA SUSUMU
IPC: C09K11/59
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To obtain through a simple process an alkaline earth metal aluminate-or alkaline earth metal silicate-based luminous phosphor with narrow particle size distribution, causing no decline in afterglow luminance even if subjected to mixing/pulverization, and having particle shape suitable as a pigment. SOLUTION: This luminous phosphor is such one as to have a matrix crystal structure of akermanite type composed of R' (at least one element selected from the group consisting of Ca, Sr and Ba), Mg, Si, O and N and also contain Eu as activator and Dy or the like as coactivator. This luminous phosphor is obtained by producing a matrix crystal of akermanite-type structure through burning a strontium nitrate-contg. stock, or by spraying a stock in the form of a solution or suspension containing the respective constitutive elements into droplets which are then heated in an oxidative, inert or reductive atmospheric airflow. This luminous phosphor has a new Mohs scale of <1, having such an afterglow characteristic as to be >=200 mCd/m2 in luminance 2 min after termination of 30 min irradiation at 1,000 lux using a daylight fluorescent lamp.

Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To make the luminance of a light emission display surface high by laminating a photoconductive layer which is larger in light refractive index than a light emission layer which is made of resin, etc., and has light accumulative materials dispersed and slanting the surface on the opposite side from the lamination surface to the lamination surface, and thus forming the light emission display surface. SOLUTION: This display surface consists of the photoconductive layer 2 of polycarbonate resin, etc., and the light emission layer 4 which is formed by mixing the light accumulative materials 5 of powder of zinc sulfate, etc., with a base of acrylic resin, etc., and forms a flat boundary surface 6 with the photoconductive layer 2. And, the external surface 3 of the photoconductive layer 2 is slanted to the lamination boundary surface and a light reflecting film 7 and a light emission display surface 8 are provided. Here, the materials of respective bases are selected so that N1<N3<N2, where N1 is the refractive index of air, N2 is the refractive index of the photoconductive layer 2, and N3 is the refractive index of the light emission layer 4.  Consequently, external light (from an air layer) efficiently enters the photoconductive layer through the slanting surface and is accumulated in the light accumulative materials in the light emission layer, and radiant light from the light accumulative materials is efficiently reflected by respective boundary surfaces, so that light with high luminance is emitted from the light emission display surface.

Filed: 1991-11-11
Abstract: PURPOSE:To enable a calling party to confirm the room where the enable is without communicating with a terminating destination in the case that an extension is transferred automatically to the room where an opposite party is. CONSTITUTION:A whereabouts managing computer 3 registers previously the exsistence of each person for every room, and when the personal extension telephone number of the terminating destination is inputted from a call originating origin through a private branch exchange 5, it retrieves the room where a terminating destination individual is from registered information on the basis of this telephone number. An automatic voice response unit 6 transfers the voice message of the whereabouts room to a call originating side through the private branch exchange 5. Accordingly, since the room where the individual is can be confirmed by the voice message without communicating with the room, dealing with the terminating destination can be executed easily.

Filed: 1991-12-06
Abstract: PURPOSE:To smoothly supply and discharge oil in a hydraulic cylinder for stably performing attitude control or the like by disposing a spool provided with a throttle part opened and closed by pilot pressure and a poppet forming a throttle hole between a pilot check valve and hydraulic cylinder. CONSTITUTION:A throttle provided with a pilot check valve 1 is interposed between a hydraulic circuit 35 of a hydraulic cylinder 2 and a control valve 36 so that smooth horizontal control for the weight of a work machine is performed. Then, a spool 6 provided with a throttle part 3 opened and closed by pilot pressure and a poppet 5 forming a throttle hole 4, is disposed between a valve 1 and the hydraulic cylinder 2. When a heavy load acts on the hydraulic cylinder 2 in the expanding direction, the spool 6 is moved by the pilot pressure as negative pressure to close the throttle part 3. Thus, oil is discharged from the hydraulic cylinder 2 only through the throttle hole 4 and the pilot pressure is gradually increased to open the throttle part 3 and supply and discharge oil smoothly.
