Title: Furnace wall structure for fluidized bed boiler
Inventor: ISEDA TAKASHI
IPC: F22B37/10
Filed: 1995-03-16
Abstract: PURPOSE: To restrain the abrasion of a water-cooled wall due to descending of particles by a method wherein a surface, covering the wall part of the water-cooled wall, is formed so as to have recessed and projected shape in order to restrain the collision of descending particles, collided against the upper surface of a refractory material lined on the water-cooled wall, against the water tube of the water cooled wall. CONSTITUTION: The upper surface of a refractory material 21, lined on one part of the peripheral wall of a furnace or a water-cooled wall 2, restrains descending particles from flowing along the peripheral surface of a water tube 2a. In this case, the upper surface of the refractory material 21 is formed so as to have recessed and projected shape so that the particles descend without colliding against the peripheral surface of the water tube 2a. The projected surface 22 of the recesses and projections is formed of a surface, covering the water tube 2a of the water-cooled wall 2, and the recessed surface 23 of the same is formed of a surface, covering the wall part 2b of the water-cooled wall 2, whereby particles, collided against the recessed surface 23 or the particles collided against said particles, descend without arriving at the projected surface.  This means that the particles are guided by the wall, forming the projected surface 22, into the furnace whereby collision against the water tube 2a of the water-cooled wall can be prevented. According to this method, the abrasion of the water-cooled wall 2 due to the descending of the particles can be restrained.

Title: Human body sensor
Inventor: FUJIMOTO ATSUSHI
IPC: G01V3/10
Filed: 1983-04-01
Abstract: PURPOSE:To obtain an inexpensive sensor capable of detecting the human body even if a blocking substance is present between the human body and the sensor, by providing one or a plurality of coils in the sensor while detecting the change in the impedance of the aforementioned coils due to the approach of the human body. CONSTITUTION:Exciting coils 2, 3 are arranged on the same plane in an overlapped state within a sensor 5 and an AC magnetic field is generated in the coil 2 by an oscillator 1. When the human body approaches this sensor 5, voltage induced to the coils is changed by the change of the impedance of the coils 2, 3 and the voltage change is detected by a signal processing part 4 to detect the approach of the human body. By this mechanism, even if the sensor 5 is embedded in the wall of a building, the approach of the human body can be detected through a blocking substance. In this case, the number of the coil may be one or three.

Title: Apparatus for production of developer thin layer forming member
Inventor: HONDA TOSHIRO
IPC: G03G15/08
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to form a developer regulating part free from ruggedness, strains, etc., at its front end even if the transverse size of a sheet spring member is large by disposing an injection port in a position opposite to the transverse central part of this sheet spring member and proximity to a recessed part and communicating this injection port and the recessed part via a recessed part for pouring disposed on another metal mold. SOLUTION: The sheet spring member 23 is first held in the holding recessed part 33 of the one metal mold 31. Next, the other metal mold 41 is placed thereon from above in such a manner that its another butt surface 42 comes into tight contact with a butt surface 32. A liquid rubber material flows immediately into the transverse central part of the recessed part 43 via the recessed part 44 for pouring and flows from the central part toward the respective ends when both metal molds 31, 42 are butted against each other and the rubber material is injected from the injection port 45.  At this time, the rubber material does not collide against each other within the recessed part 43 and since the distances from the transverse central part to the respective ends are not long, the smooth pouring of the rubber material to the respective ends is made possible and the occurrence of the strains, etc., in the developer regulating member is averted.

Filed: 1993-03-18
Abstract: PURPOSE:To surely prevent casting glare to other vehicles by estimating the distance between vehicles according to the distance to one vehicle detected from an image signal and to the relative velocities of the vehicles, and controlling a headlamp based on the distance between the vehicles. CONSTITUTION:The situation in front of a vehicle is photographed for every predetermined period T. Another vehicle is detected according to an image signal obtained by the photographing, so as to detect the distance to this vehicle and the relative velocities of the vehicles. The distance between the vehicles is estimated from these detected values and for a period Tn shorter than the period T. At least either the direction or range of illumination of a headlamp is controlled based on the estimated distance between the vehicles. Therefore, even if it takes time to measure the distance and relative velocities between the vehicles, the effect of this is eliminated, and casting glare to other vehicles can be prevented.

Title: Optical waveguide ring laser
IPC: H01S3/08
Filed: 1992-03-16
Abstract: PURPOSE:To obtain an optical waveguide ring laser capable of controlling arbitrarily an oscillation wavelength by a method wherein a wavelength selecting element, which transmits light of a specified wavelength, is provided in a ring laser resonator. CONSTITUTION:The so-called narrow-band transmitting filter, which transmits light of a specified wavelength and stops light other than the light of a specified wavelength, is added in a ring laser resonator 14 constituted of an Er-doped optical waveguide as a waveguide selecting element 15. Thereby, a resonator circuital loss in a wavelength other than that in the transmitting band of the light is increased and it becomes possible to make a laser oscillation take place in an arbitrary wavelength to coincide with the transmitting wavelength of the element 15. As the narrow-band transmitting filter, a dielectric multilayer film filter, which is superior in the controllability of a transmitting wavelength and a transmitting band, is practical. It is desirable that the element 15 is arranged in a position immediate before an excitation light circuits in the resonator 14 and is emitted through an excitation light incident port or is arranged in the optically rear position of the Er-doped optical waveguide part.
