Title: Method for calibrating receiving system and/or sending system controlling active antenna string and corresponding mobile station
Inventor: BURSZTEJN JACQUES
IPC: H04B17/00
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a method which is easy to be implemented and is inexpensive by using at least one among mobile stations that exist in the current cell as a calibration transponder station which receives and/or sends at least one test signal that calibrates a receiving system and/or a sending system. SOLUTION: A base station sends a sending request for a prescribed test signal to a calibration transponder station, and the calibration transponder station receives the sending request and sends the prescribed test signal as it is requested. The base station receives a test signal, analyzes it and decides calibration that should be performed on a receiving system in accordance with analytical results. It is possible to repeatedly perform execution by using plural calibration transponder stations in order to improve the quality of calibration to be carried out. A request that is sent to the calibration transponder station by the base station can designate some characteristics of a test signal which has to be answered and sent by the calibration transponder station.

Title: On-line attenuating method for limit cycle of nonlinear system
Inventor: OTSUKI KOICHI
IPC: G05B11/36
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To monitor the dead zone of a controlled system on-line and set a compensator which compensates the dead zone on-line by estimating an inverse function by using an estimated dead zone and fuzzy inference, and performing carry-up by using the inverse function. SOLUTION: A state monitor part 5 inputs the target value ym, the output (y) from the controlled system 3 and the output (u) from the compensator 2 to decide whether or not there is a limit cycle and also hold those data in time series. An inference part 6 extracts data needed to design the compensator 2 (e.g. a value compensating the dead zone of the controlled system 2 and value compensating hysteresis) by using fuzzy inference and supplies them to the compensator 2 while abrupt variation is suppressed by a linear filter 7. The compensator 2 inputs the necessary data and performs carry-up and automatically sets nonlinear input/output characteristics of the controlled system so that the input/output characteristics at a corresponding point of time are compensated.

Title: Toner jet recording apparatus
Inventor: TSUDA MASAYUKI
IPC: B41J2/385
Filed: 1990-09-19
Abstract: PURPOSE:To obtain a recording apparatus capable of obtaining sufficient gradation, in the recording apparatus consisting of an electrode with an aperture selectively applying a powder to a support such as plain paper and the carrier supporting the powder, by making the diameter of the aperture variable. CONSTITUTION:When signal voltage is applied to the control electrode layer 8 of an aperture electrode 9 from a signal source S, the flow of toner T is modulated and controlled on the basis of the signal voltage. That is, when negative voltage is applied to the control electrode layer 8 from the signal source S, an electric field going toward the control electrode layer 8 from a reference electrode layer 7 is generated and the toner T positively charged in an aperture 5 passes through the aperture 5. At this time, the pressure of a liquid 20 is raised in synchronous relation to the signal voltage by a pressure pump 22. Whereupon, the diameter of the aperture becomes small and the amount of the toner passing through the aperture can be sufficiently controlled as compared with the case only of signal voltage. By this method, since the amount of the toner passing through the aperture can be sufficiently controlled, sufficient gradation becomes possible.

Information on the bit is written as a ninth bit data of image data to the memory with the same timing as the image data. The written image data is read from the memory synchronously with a send timing to an engine. The read image data including the final data recognition bit is sent to a final data-checking part in an engine I/F main control part and checked.

IPC: G06F1/00
Filed: 1986-10-22
Abstract: PURPOSE:To decrease the number of timer circuits needed for monitor of the time passed between a changing point and the next changing point of each input signal, by storing the monitor frequency counted between a changing point and the next one into an address corresponding to the corresponding input signal in a memory. CONSTITUTION:When both memories 21 and 31 are set under the same writing conditions, only the lowest bit of a bus line 60 is controlled independently by a line selecting circuit 34. The lowest bit of the line 60 is supplied to a binary number adding circuit 22 when a read signal is delivered from an address generating circuit 11 via a signal line 70. The circuit 22 detects the state of said lowest bit and decides to start or discontinue addition. Thus the time passed between a changing point and the next changing point of an optional input signal is read out in the form of the addition result of binary numbers. Then the number of timer circuits can be decreased for monitor of said time passed.

IPC: H01L21/76
Filed: 1991-09-30
Abstract: PURPOSE:To reduce the manhours for manufacturing a thick semiconductor crystal layer by a method wherein, in order to form an aperture part insulating film, the insulating film once formed on the surface of an epitaxially grown semiconductor crystal layer is removed to be epitaxially grown again on the whole surface. CONSTITUTION:An aperture part insulating film 8 is formed on a semiconductor substrate 1 exposed in an aperture part 7 to be connected to an insulating film 2. That is, when the whole body is heat-treated at 1000 deg.C for 70 minutes, silicon on the semiconductor substrate 1 is oxidized to form an oxide film in almost the same thickness as that of the insulating film 2 thereby enabling an aperture part insulating film 8 to be detected. At this time, the surface of a silicon carbide crystal growth layer as well as the side of the second aperture part 7 are oxidized so as to form a crystal deposited oxide film 9. Next, the crystal growth layer oxide film 9 is removed and then a semiconductor crystal layer 11 is epitaxially grown. Through these procedures, the semiconductor crystal layer 11 can be formed on the insulating film 2 without requiring any complicated steps such as the formation and removal, etc., of an oxidation preventive film at all.
