Title: Pump controller
Inventor: KOBAYASHI SHUICHIRO
IPC: F04B49/06
Filed: 1987-12-29
Abstract: PURPOSE:To control the number of units in waste water/rain pump group by means of unattended and automatic operation by providing a means which predicts and operates the maximum value and minimum value of water levels in a pump well in a prescribed time ahead. CONSTITUTION:A number control operation part 14 calculates the flowing-in rate of the pump well 4 from the water level of the pump well 7 and the total discharge flow rate 8 by a self regression model, calculates the maximum value and minimum value of the total discharge flow rate of the pump group 5. Furthermore, the maximum value and the minimum value in the prescribed time ahead is predicted from the maximum value and minimum value of the discharge flow rate, the estimated flowing-in rate and the present water level. The number of operation pumps is decided and the objective value of the water level is calculated from the obtained maximum predictor of the water level and the minimum predictor of the water level. The information are outputted to a process input output processing part 10 through a number control sequence processing part 17 and a PI control operation part 20, and the start/ stop of the pump group 5 is executed. Thus, the optimum control of the number of the pumps corresponding to the flowing-in rate can be executed without unattended operation.

Title: Range-finder for camera
Inventor: TAMAKI KAZUHIRO
IPC: G01C3/06
Filed: 1989-12-26
Abstract: PURPOSE:To perform consecutive range-finding from infinity to the shortest distance in the case of macro photographing by making a reflected light beam from an object which is projected by a 1st light source incident on a photodetector in the case of normal photographing and making a reflected light beam from the object which is projected by a 2nd light source incident on the photodetector in the case of macro photographing respectively. CONSTITUTION:By taking the intersection of the light beam projected by the 2nd light source 14 with the optical axis 17 of a light receiving lens 16 as a boundary between the normal photographing and the macro photographing, the reflected light beams from the object which are projected from the 1st light source 11 and the 2nd light source 14 are made incident on the light receiving device 15 in the case of the normal photographing and in the case of the macro photographing respectively. As a result, in the case that the photodetector 15 does not receive the reflected light beam from the object when the 1st light source 11 emits the light, it is because the reflected light beam from the object is faint or because it is out of the light receiving surface of the light receiving device 15. When the 2nd light source 14 is allowed to emit the light continuously and the reflected light from the object is made incident on the photodetector 15 after turning off the 1st light source 11, range-finding is performed to the object in a macro photographing area. At such a time, the action of range-finding in the infinity is started in the case that the light is not made incident on the photodetector 15. Thus, the consecutive range-finding is performed from the infinity to the shortest distance where the macro photographing can be possible.

Abstract: PURPOSE:To obtain a flame retardant, low pressure-loss filter medium by using hot melt adhesive fibers in which a lower melting point component and a higher melting point component are combined and gluing thermally a flame retardant at least on the surface of the lower melting point component of the adhesive fibers. CONSTITUTION:In hot melt adhesive fibers of conjugate fibers, a lower melting point component such as a low melting point polyester is used at least for a part of the circumference in the cross section of a fiber, and a higher melting point component is used for the rest of the fiber. An aqueous solution in which a flame retardant such as hexabromocyclododecane is dispersed or dissolved is deposited on nonwoven fabric containing the hot melt adhesive fibers. The coated fabric is heat-treated at a temperature above the melting point of the lower melting point component to glue the flame retardant on the surface of the adhesive fibers. Since no binder is used which has been necessary so far for fixing a flame retardant or bonding fibers, a filter medium with good permeability can be obtained.
