Abstract: PURPOSE:To improve washing efficiency by providing the generating means of detergent foam, discharging pipe of the detergent foam and defoaming device and arranging a centrifugal fan in the flow of the detergent foam for the defoaming device. CONSTITUTION:Detergent liquid 16 is put into a stock part 3 of a washing tank and air is fed with pressure from the bottom part of the washing tank through a pressure feeding pipe 7. Therefore, detergent foam 17 is generated and laundry 2 is washing since this detergent foam 17 gets contact with or passes through the laundry 2. The detergent foam 17 getting contact with or passing through the laundry 2 is passed through a porous body 11 in the upper part of the washing tank and discharged from a foam discharging pipe 9 to an external part. Since the foam discharging pipe 9 is equipped with a defoaming device 15 in the middle and the discharged detergent foam 17 is defoamed by the defoaming device 15 and discharged as the detergent liquid. The detergent liquid is discharged after extremely reducing the capacity. Since this defoaming device 15 arranges a centrifugal fan 21 in the flow of the detergent foam, the detergent foam 17 sent from the upper part is sucked from a central part 22, dispersed in a peripheral direction along an impeller 23 and broken by mechanical force at that time by rotating this centrifugal fan.

IPC: B65H7/06
Filed: 1987-11-27
Abstract: PURPOSE:To make it possible to precisely detect a conveying condition by detecting and counting bundles of sheets conveyed by a conveying means so that data of a full number are delivered when the counter number exceeds a regulated number while data of a full stay are delivered when the detected time exceeds a regulated time. CONSTITUTION:Sheets P0 such as bundled banknotes or the like, are fed by a conveying means 2 in a sheet stacking device 1, and are charged into a storage means 4 after a detecting lever 3a of a detecting means 3 is actuated. Detection signals from the detecting means 3 are counted by a number data output means 5 through a CPU 10, and when thus counted number exceeds a regulated number, the CPU 10 allows an recognition control means 9 to deliver data of a full number (warning). The time of output of the detection signals from the detecting means 3 is counted by a staying data output means 6, and when thus counted time exceeds a regulated time, the recognition control means 9 delivers data of a full stay. Further, the drive of the conveying means 2 is stopped simultaneously with the delivery of the data of a full number and the data of a full stay. Thus, a full condition of the storage means is precisely detected, thereby it is possible to prevent occurrence of an abnormal condition.

Abstract: PURPOSE:To accurately align the developing position of each color by correcting the degree of slur so that dots of magenta toner and dots of cyan toner are arranged in a dot line based on the dots of yellow toner as a reference. CONSTITUTION:Three exposure LED arrays 21, 24, 27 are recorded by using a light timing clock at the same interval of the array 21 over the entire circumference of a photosensitive drum and the recording state of the toner of each color is expanded partially and checked. Each dot of yellow, magenta and cyan is recorded while being slurred in the direction of rotation of the photosensitive drum and the deviation is measured corresponding to an output pulse interval of a rotary encoder 1 based on the dots of yellow color. Then the light timing of the exposure LED array recording magenta and cyan is written in each ROM to form a light timing clock generating means.

IPC: H04B7/26
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To avoid collision in radio local area network environment by exchanging handshake information of data showing power levels which stations on transmission and reception sides are permitted to use. SOLUTION: Handshake information includes data showing the power levels the stations on the transmission and reception sides can use. Information transmitted from an interface module is issued from a host 503 and reaches a module through a CPU address bus. A radio controller 504 acquires the intensity display of a received signal and properly informs CPU 501 of it. A radio data unit 504 modulates a signal received from CPU 501 and makes it proper for transmission through a radio transmitter 506. A radio signal received from a radio receiver 506 is inversely demodulated to a format proper for transmission to CPU 501 or the host 503 by a radio data unit 504.

Abstract: PURPOSE:To adjust suitable sucking force at every cleaning surface regardless of mesh clogging by clearly showing an almost suitable negative pressure position corresponding to the type of the cleaning surface at one spot in a flowing route from a hose to the inside of a dust collecting device. CONSTITUTION:A variable resistor 22 is built in an output adjusting device 24 which is provided on a grip part 23 of a hose 3. When a handle 24a is moved by being matched to an intensity scale 24b which is displayed on the input adjusting device 24, a resistance value is changed and the sucking force of an electric air blower 6 is changed. Since negative pressure in sucking port 32 is almost in proportion to the negative pressure in the inside of dust collecting device 4, when the optimum sucking force for each cleaning surface, namely, the negative pressure in the inside of the dust collecting device 4 is investigated, which cleaning surface the negative pressure in the inside of the dust collecting device 4 is optimum to is decided and displayed by a display device 25. Thus, since the almost suitable negative pressure position is clearly shown at every type of the cleaning surface, the sucking force can visually confirmed at all times and even when the dust collecting device is clogged, the sucking force can be exactly and easily adjusted to the optimum sucking force.
