Title: Molten granular resin cooling method and its device
Inventor: NISHIJIMA MASATAKA
IPC: B29B13/00
Filed: 1978-07-13
Abstract: PURPOSE:To obtain fully dried pellets by bringing molten granular resins into contact with water mist as the resins freely drop down on an oblique drain board, and by draining the water while they move down thus effectively cooling the pellets that are made by means of the hotcut method. CONSTITUTION:Molten pellets supplied from an opening 2, pass through the mist of cooling water as they freely drop inside of a spray room to an oblique surface of a drain board located on the bottom of the spray room. Then the water is drained while the pallets slide down the slope, and are dropped from the lower end 5 of the board and are collected. These water drained pellets are fully solidified but still warm and they hold enough temperature to evaporate water remaining in the pellets with their own heat. Thus the remaining water in the pellets evaporates and the pellets are dried until they contain almost no water during a cooling process to cool the pellets enough to be transfered, packed and shipped.

Abstract: PURPOSE:To extract a highly effective error signal and to obtain sufficiently high equalizing capacity by obtaining an error signal and a polarity signal for adaptive amplitude equalizer control before the equalization of a post transversal equalizer. CONSTITUTION:At this automatic adaptive equalizer, a code converter 4 which extracts an identification signal that is the output of an A/D converter 6 from the polarity signal (DF, DO), the error signal (YP, YQ), and a clock signal is provided. A control signal generator 3 is constituted so as to generate an in- phase control signal (Re(-1), Re(+1)) and an orthogonal control signal (Im(-1)), Im(+1)) from the polarity signal and the error signal before the equalization of a transversal equalizer 7.

In such a manner, the highly effective error signal can be extracted, and the adaptive amplitude equalizer can be surely controlled to obtain the sufficiently high equalizing capacity.

Filed: 1989-04-07
Abstract: PURPOSE:To precisely position a prescribed retrieving image in a prescribed position with high accuracy by providing a sensor which detects such a retrieval mark as a frame mark added to a microfilm on a position deviating from a projection optical part. CONSTITUTION:Each distance value between frame marks (e) constituting of target image frame groups 90 and 91 is stored in a memory means for a period after the sensor 43 detects a target item mark D before it detects a following item mark D. In this case, the position of the sensor 43 is shifted from that of an image projection part. To correct the deviation, each image frame is copied while a film F is fed backward from latest end frame up to its top frame in one-frame units after the latest image frame in the target image frame group 91 is positioned on the projection optical path part S. In the backward feeding, the film F is fed based on the stored distance values. Without depending on the frame mark, the film is fed based on the stored distance values between the images. Thereby, the prescribed image can be precisely positioned on the projection optical path part if recording is performed with the image frames displaced.
