Abstract: PURPOSE:To prepare 5-fluorouracil useful as a carcinostatic agent for cutaneous cancer, etc., economically, in high yield, by thermally decomposing 6-hexafluoroisopropoxy-5-fluoro-5,6-dihydrouracil (a novel compound) at a specific temperature. CONSTITUTION:The novel compound of formula III obtained by the reaction of the compound of formula I with the compound of formula II and fluorine gas is heated at 100 deg.C- the decomposition temperature of the objective compound (282 deg.C) in the absence or presence of a solvent, preferably a solvent having a boiling point of >=100 deg.C, e.g. xylene, dimethylformamide, dimethylsulfoxide, acetic acid, liquid paraffin, etc. to obtain the objective compound of formula IV.

Filed: 1986-01-29
Abstract: PURPOSE:To make controllability after handling a paper jam improvable, by resetting a paper-jam detecting device when reinstallation of a paper refeed cassette to its body part is detected after the paper jam handling. CONSTITUTION:In case of a duplex mode, a controlling device makes a first selector claw 60 situate an upper step and a second selector claw 65 a lower step, respectively, while copying paper out of a pair of paper discharge rollers 21 is reversed by a turnover roller 76, housing it in a paper refeed cassette 50. At this time, even after the elapse of time limit of a timer to be set after a sensor Se2 detects a copying paper rear end, supposing a sensor Se3 is left turned on intact, it is judged as a paper jam whereby the drive of a copying paper conveying device is stopped. Next, after pulling out the paper refeed cassette 50 and handling the paper jam, if the paper refeed cassette 50 is installed in its body 31, this is detected by a sensor Se1, and the timer is set, while the drive of the copying paper conveying device is reopened. Thus, the paper jam of the succeeding copying paper is obviable and, what is more, controllability at the time of reinstallation of the paper refeed cassette is improved.

Title: Led array head
Inventor: OSAWA YASUHIRO
IPC: H04N1/036
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To inhibit with an easily manufactured structure adverse effects due to side face light from the side face of an LED light-emitting section, having projecting structure with a structure. SOLUTION: A light-absorbing material 3 is embedded among each LED light-emitting sections 2 having projecting structure. As a result, even if a side face light P1 is emitted in the array direction in a substrate surface from a side faces 2b of the LED light-emitting sections 2, the side face light P1 is absorbed and damped in the light-absorbing material 3 embedded among the LED light-emitting sections 2, and the side face light is changed into light which hardly has effects even if it is emitted to the outside. A photolithographic method need not be used for the process here, in which the light-absorbing material 3 is embedded, and the alignment of photomasks is not also required, thus inhibiting adverse effects by the side face light P1, with a structure in which manufacture is easy.

Title: Field effect transistor
Inventor: MINEMATSU KIYOSHI
IPC: H01L29/772
Filed: 1978-02-22
Abstract: PURPOSE: To suppress the distortion in resistance value, by feeding the AC voltage having equal amplitude and inverted phase to the source and drain and feeding DC voltage to the gate.  
     CONSTITUTION: Taking AC input of FET as eg, output AC as ig, gate voltage VG, and pinch off voltage as V p , ig = eg.K.(VG-V p )-Ke 2 g/2 and the term in proportional to e 2 g is a cause to the distortion. When the AC input is separated onto two voltages of ±eg/2 and fed to the source and drain, the second term is eliminated. That is, the AC voltage VSD/2 at the intermediate point of source and drain of FET channel is fed to the control voltage between the gate and source, avoiding the resistor RSO from being affected. No distortion is caused by grounding the voltage at the intermediate point like this.
