Patent JP-H01141482-A (JP)
Title: Image processor
Inventor: FUKUDA MIKA
IPC: H04N19/59
Filed: 1987-11-27
Abstract: PURPOSE:To shorten an arithmetic time at the time of reproducing partial image data by executing only an operation necessary for obtaining the reproduced value of a picture element designated beforehand at the time of inverting. CONSTITUTION:Reproducing image data x0-x15 are obtained by executing a one-dimensional inverse discrete cosine conversion(IDCT) to converting coefficients F0-F15. On the other hand, generally, images have frequency characteristics that an energy is concentrated in a low frequency area and that the energy of a high frequency area is small, and the converting coefficient at such a time is made into approximately 0. From such characteristics, there is no problem in the view of a picture quality even when the converting coefficient of the high frequency area with the small energy is not used for inverting. Namely, at the time of preparing thinning images such as x0, x4, x8 and x12, not that the images are reproduced from all converting coefficients of F0-F15, but that the images are reproduced only by the converting coefficient of the low frequency area with the large energy. Thus, the image can be recognized in an early stage.

Title: Magnetizing current optimization equipment for linear induction motor and elevator cage door control system
Inventor: REDDY NARASIMHA K
IPC: B66B13/08
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics of a linear induction motor driving an elevator cage door by changing a magnetizing current to a linear motor in response to the load of linear motor. SOLUTION: A magnetizing current level is set to a high value during door opening operation. During door closing operation, the magnetizing current level is set to a medium value. And by the signal from a first positioning system 42, if a door is completely placed at a door closing position by software through a feedback system, then the magnetizing current level is set to a low level. When a force is being applied to keep an elevator cage door opening, the first positioning system 42 detects this situation, this information is sent to a controller 60 through a first cable 68, and magnetizing current level is increased to a high value thereafter. By optimizing the magnetization current, the temperature rise in a motor can be reduced considerably.

Title: Facsimile equipment
Inventor: IGUCHI TETSUYA
IPC: H04N1/44
Filed: 1987-11-30
Abstract: PURPOSE:To transmit and receive a confidential document by not immediately recording a reception image but storing image data in a specific mode and recording the reception image corresponding to a register password in accordance with input of this password thereafter. CONSTITUTION:When a line is connected, the reception side generally informs the transmission side of its own machine type, capability, and function, and the control signal which indicates mode setting is sent from the transmission side in response to them. When this control signal indicates that a specific mode should be set, that is, an image should not be recorded immediately after reception, an image data storage control means 16 stores received image data in an image data storage means 26. Consequently, transmission information is not seen by unspecific persons because a copy of a transmission document is not immediately outputted. If a password is registered in a password storage means 28 when this password is inputted for the purpose of recording the image, the image data storage control means 16 reads out image data corresponding to this password from an image data storage means 26 and subjects it to a prescribed signal processing and gives it to an image recording means 14 to record it.
