Title: Printing-paper protection controlling method of electrophotographic device
Inventor: NISHIMAKI MASAO
IPC: G03G15/22
Filed: 1980-02-06
Abstract: PURPOSE:To prevent a printed form from changing in color owing to staying it on a heating plate for a long time, by forcibly feeding the form even if no print command arrives if the printed form stays on the heating plate for the constant time. CONSTITUTION:Counter 10 for the stop time of a continuous form counts signals from AND20 with both time signal A and jam signal B, but never performs the counting operation during arrival of paper feed signal C. After the counting operation continues for a certain time, inverter 30 performs inversion with output 1 and FF40 is set. With output Q, counter 10 is reset and its signal is inputted to MS50. The output of MS50 sets FF60, and in response to output Q of FF60 and signal B, motor drive signal D is sent out of NAND70 to feed the paper forcibly. Then, FF60 is reset by NANDs 90 and 90' and inverter 101 through page-number control counter 80 and with page signal E, form length signals L and L', etc., to stop the paper, and this operation is performed successively to prevent the paper from growing yellowish.

Title: Brushless dc motor and its permanent-magnet holding method
Inventor: TETSUYA KAZUHIRO
IPC: H02K1/27
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the decrease of the main magnetic flux of a brushless DC motor and suppress its cost-up which are otherwise caused by gaps for disposing therein the fastening members of its each permanent magnet, by disposing the fastening members on both the circumferential sides of its each permanent magnet present in the insertion portion thereof to make the restriction of the circumferential movement of its each permanent magnet possible. SOLUTION: In a brushless DC motor, the circumferential dimension of each insertion portion 43 is made larger than the circumferential dimension of each permanent magnet 44, while a pair of fastening members 49, 49 made of a non-magnetic material are disposed on both the circumferential sides of each permanent magnet 44 present in each insertion portion 43. Further, the circumferential movement of each permanent magnet 44 disposed in each insertion portion 43 of a rotor core 42 is restricted to be held by the pair of fastening members 49, 49 disposed in gaps present on both the circumferential sides of each permanent magnet 44, but since the position of the gap for disposing each fastening member 49 therein is separated largely from the path of the main magnetic flux of the motor, its magnetic resistance is not increased by the gap.  Also, each fastening member 49 is a part used already in conventional motors. As a result, the decrease of the main magnetic flux is not effected and the cost-up caused by increasing the kinds of parts can be suppressed.

Title: Two staged feed mechanism
Inventor: ITOU TAKESHI
IPC: B23B47/18
Filed: 1983-02-01
Abstract: PURPOSE:To increase the efficiency of a mechanism by enabling both quick feed and rotary machining feed by means of the combination of an eccentric cylinder and gear feeding. CONSTITUTION:The travel of a spindle 52 allows a spindle 1 to advance with respect to a base body 4. This action does not cause the spindle 52 to rotate, due to its eccentricity. The rotation of a motor 7 causes the spindle 1 and a thread cylinder 13 to rotate through a wheel train 72, 62, 63, 14 and, since a nut 53 is unable to rotate, the thread cylinder 13 and the spindle 1 are rotated and sent out at the pitch of the nut 53, carrying out the machining such as tapping, etc. The detector 8 detects the position at which machining is completed. Due to this detection, the motor 7 is reversed and stopped, and then, a cylinder 5 is reversed, and a switch 92 is turned on, completing one cycle.

Abstract: PURPOSE:To provide the liquid crystal display device which expands the visual field characteristic by a diffusion film and can prevent the degradation in resolution by specifying the thickness of a transparent substrate on the front surface side. CONSTITUTION:The liquid crystal display panel 1 is constituted by a liquid crystal layer 3 by sealing a liquid crystal sandwiching material between two sheets of the transparent substrates 2a and 2b having transparent electrode films, providing the front surface (display surface side) and rear surface thereof respectively with polarizing plates 4a, 4b and providing the front of the polarizing plate 4 further with the diffusion film 5.
