Title: Electrolytic dephosphorizing device
Inventor: URABE TOYOYUKI
IPC: C02F1/465
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To maintain performance for removing a phosphorus component for a long period, in an electrolytic dephosphorizing device in which an anode and a cathode are immersed into water containing the phosphorus component, and between the anode and the cathode are electrified to electrolyze the water and the phosphorus component is made hardly insoluble in water and is deposited. SOLUTION: The device has a flow passage 8 through which water containing the phosphorus component is allowed to flow from the upper part to the lower part, and is provided with the cathode 21 formed of an assembly of small pieces 4 charged into a metallic cage 1 having a net shaped bottom plate 3, at the upstream side of the flow passage 8, and a net shaped anode 22 arranged oppositely faced to the bottom plate 3 of the metallic cage 1, at the down stream side of the flow passage 8, and also the cathode 21 and the anode 22 are installed across the cross-sectional area of the flow passage 8.

Title: Object recognizing device
Inventor: FUJITA KEIJI
IPC: G01B17/06
Filed: 1984-10-15
Abstract: PURPOSE:To recognize the exact shape of an object which is not obtainable with a ITV camera alone by having a position detector for detecting the part where the distance from an ultrasonic sensor is shortest on the object to be detected. CONSTITUTION:An object recognizing device has the ultrasonic sensor 4. All e solids projected by the TV camera 3 are projected to a plane when the case of recognizing, for example, rectangular parallelepipeds which are stacked bulk from above is considered. However, the position of the rectangular parallelepiped existing uppermost among the bulk-stacked rectangular parallelepipeds is known if the shortest distance from the sensor 4 is detected by scanning the sensor 4. The exact shape of the object which is not obtainable with the ITV camera alone is thus recognized.

Title: Printer system
Inventor: MASADA KAORU
IPC: G06F3/12
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a printer system preventing a congestion of traffic on a network. SOLUTION: When performing a state inquiry from a host computer (host) to a network printer 6, 'network address of host' and 'storage time of host information' are simultaneously transmitted as host information. The network printer 6, which receives this host information, stores the host information in a report destination host table 7. When a state change occurs in the network printer 6, the network printer 6 reports the state change to the network address (host) shown by the host information stored in the report destination host table 7.  Besides, since the host information to be stored in the report destination host table 7 is stored in the report destination host table 7 just for 'storage time of host information' from the storage of the host information, the state inquiry is performed to the network printer 6 once the 'storage time of host information' by the host and the storage of the host information is continued.

Title: Method and device for detecting liquid level by use of ultrasonic wave and device therefor
Inventor: JOSA ITSUO
IPC: G01F23/28
Filed: 1990-08-16
Abstract: PURPOSE:To surely achieve an object with no fear of erroneous operation and to provide a miniaturized and lightweight liquid level detecting device which is highly portable, by analyzing received multiple reflection waves of ultrasonic pulses reflecting at the inside and outside of the wall of container, with the use of two gate circuits. CONSTITUTION:A trigger pulse is generated at the rise of a synchronizing signal delivered from a synchronizing circuit 1, and is directed from ultrasonic probes P1, P2 to the outer wall of a liquid container Ve. The ultrasonic pulse is subjected to multiple reflection between the outer wall and inner wall of a container so that the echo thereof is received by the probe P1, and is then converted into an electric signal which is then received by a receiver 3 so as to be amplified as necessary. When the probe P1 is above the liquid level WL, the ultrasonic wave transmits substantially through gas G so that it is subjected to multiple reflection between the wall surfaces of the container so that it does not soon decay. If the probe P1 is below the liquid surface WL, the ultrasonic transmits through the liquid L so that it readily decays. Thus received signals are compared with each other by a comparator 4, thereby it is possible to detect the liquid level.

Title: Laser distance measuring instrument
Inventor: TAKAHASHI HIDEMI
IPC: G01S17/32
Filed: 1986-09-16
Abstract: PURPOSE:To increase a frequency shift quantity and the number of times of repetition of modulation, to impose linear frequency modulation, and to accurately measure distance by imposing frequency modulation on the output laser light of a laser resonator by using an acoustooptic modulator installed outside the resonator, extracting part of the frequency-modulated laser light as reference light and projecting it on a body to be measured, and detecting the frequency difference between the reflected light and reference light. CONSTITUTION:The output light of a laser 1 is projected on the acoustooptic modulator 11 to generate diffracted light. A lens 13 converges the laser light so that fast modulation is possible. The frequency of the diffracted light shifts from the oscillation frequency of the laser by the oscillation frequency of a power source 12 for modulation which drives the acoustooptic modulator 11. For the purpose, the oscillation frequency of the power source 12 for modulation is varied like a triangular wave to impose the frequency modulation. Then, the diffracted light is reconverted by a lens 14 into parallel light. Consequently, the frequency-modulated laser light is projected on an object 7 and the frequency of the beat signal between the reflected light and reference light is measured to find the distance to the object.
