Title: Image forming device with document feeder and carrying wound body used for device
Inventor: HATAKEYAMA TAKUYA
IPC: B65H43/00
Filed: 1988-02-05
Abstract: PURPOSE:To detect a thin document or document with high transparency while securing a document conveying force by detecting the document from the contrast between a part to be detected and the ground of the document. CONSTITUTION:Specular surface reflecting aluminum sheets 35a-35d as means to be detected are stuck at positions of the belt 33 for conveying documents M corresponding to rear end inner corner parts of documents of various sizes. Further, the downstream inner corner of the document M mounted at a document mount reference covers the specular surface reflecting aluminum sheets 35a-35d partially corresponding to the document sizes. The document M is scanned by a lamp 6, mirrors 7-9, and a lens 11 to judge how many specular surface reflecting aluminum sheets among 35a-35d are covered. In this case, a detecting means 15 performs detection according to the contrast between the specular surface aluminum sheets and the ground of the document M. Consequently, even when the document M consisting of thin paper or high- transparency paper is mounted on a mount base, it is detected while the document conveying force is secured.

Title: Apparatus for identifying moving object
Inventor: NAGATA KAZUO
IPC: G01S13/74
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To allow communication in a short time without radio interference even if a plurality of interrogators exist in a communication area by a method wherein an interrogator communicates with a responder and also transmits a transmission stop instruction or a stop cancellation instruction of a response wave as an interrogation wave. SOLUTION: A plurality of responders 51 exist in a same communication area, and an identification No. is assigned to each of them. A control circuit 7 of an interrogator 40 transmits unmodulated waves as interrogation waves from an antenna 3., The responder 51 actuates a control circuit 12 or the like when it detects the interrogation waves for transmitting response waves based on the identification No. The interrogator 50 receives a plurality of response waves at the same time, demodulates 6 the response wave having the highest signal level and outputs to the control circuit 7. The interrogator 50 transmits a response stop instruction together with the identification No. as interrogation waves when it terminates communication with the responder 51.  The responder 51 comes into a response stop state by the control circuit 12 when its own identification No. coincides with the transmitted No. When communication with all of the responders 51 is completed, the interrogator 50 transmits a response stop cancellation instruction as interrogation waves.

Another means writes successively the read-out image data on each picture element into the line memories 31a - 31c. Then the working of the reading means is stopped when the image data on the final picture element of a single row is read out of the memory 20 after applying the matrix arithmetic to the image data on (p X q) picture elements read out of the memories 31a - 31c. Under such conditions, the prescribed value is given to the writing means and then written into the memories 31a - 31c. Then the working of the reading means is restarted. Thus a window image is processed at a high speed when the matrix arithmetic is applied to the window image taken out of the memory 20.

Inventor: RA ZAIGEN
IPC: D06F17/08
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent laundry from being tangled at the time of washing by a method wherein a pulsator which vertically moves depending on the rotating direction, and a variable pulsator which expands or contracts in the radial direction corresponding to the above-mentioned pulsator, are provided, and concentric water streams in the horizontal direction by the pulsator are broken by water streams in the radial directions by the variable pulsator. SOLUTION: When a rotating shaft 600 is rotated by a driving part, a pulsator 300 and a variable pulsator 700 are rotated. At this time, the pulsator 300 is normally or reversely rotated along a spiral guide groove 201 on the internal surface of a washing tank 200, and vertically moved along a key groove 605 on the rotating shaft 600. For this reason, a heart-shaped eddy-current is generated in the washing tank 200. Then, when the pulsator 300 ascends, the variable pulsator 700 is pushed upward, and the length of the variable pulsator 700 is contracted, and at the same time, the body of the variable pulsator 700 radially expands. At the time of the descent, the length of the variable pulsator 700 extends, and at the same time, the body contracts in the radial direction.  By this method, washing water repeats concentrations and dispersions in the radial direction, and breaks the heart-shaped eddy-current.
