Title: On-load tap changer
Inventor: FUWA YASUSHI
IPC: H01F29/04
Filed: 1983-05-11
Abstract: PURPOSE:To eliminate a circulating current and make a current-limiting impedance and an auxiliary arcing contact unnecessary by a method wherein, after a prescribed tap is opened, a load current is born by a non-linear resistance until a tap of the next step is connected. CONSTITUTION:Taps 2, 3 are provided to a transformer winding 1. Main arcing contacts 6, 7 are connected to the taps 2, 3 through tap-selectors 4, 5. A load 11 is connected to a collector contact 10. A non-linear resistance 12 is provided between the collector contact 10 and the tap-selector 5. Because a transient load current is born by the non-linear resistance 12, a circulating current is eliminated. Therefore, a current-limiting impedance and an auxiliary arcing contact are not necessary. Moreover, as a current to be discontinued by a main arcing contact is the load current only, the circuit-breaking burden of the main arcing contact is reduced.

Title: Cylindrical roller bearing
Inventor: MURAI TAKASHI
IPC: F16C33/34
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce vibration/noise by making a contour along an axial direction of a roller rolling contact surface a linear shape parallel to a shaft at least in a center part and specifying inclination of a part opposed to the roller rolling contact surface of a cage pocket for a straight line parallel to a revolution center shaft of a bearing. SOLUTION: A center part of a contour along an axial direction of a rolling contact surface of a cylindrical roller 5 is made a straight part 5a parallel to a shaft and both the left and right sides 5b are formed into crown shapes. Each of inclination in the circumferential direction and the radial direction of a surface 4a opposed to the roller 5 in the circumferential direction of a pocket 4 of a cage 3 is made 1.5/1000 or below of the length of the roller 5. As a result, the whole of the straight part 5a of the rolling contact surface of the roller 5 is relatively pressed so as to come into contact with the surface 4a, and the roller 5 is revolved while the attitude of the roller 5 is automatically adjusted to an attitude along the surface 4a.  By suppressing inclination of the surface 4a, the roller 5 is always controlled in attitude in a direction that the inclination is reduced and is moved at a stable revolving attitude in a non-load zone. Therefore, vibration and noise of a bearing due to fluctuation of the attitude of the roller 5 during revolution can be suppressed.

Title: Picture reader
Inventor: KOBEGAWA MINORU
IPC: H04N1/38
Filed: 1989-04-05
Abstract: PURPOSE:To prevent such a defective case that the boundary part and the periphery of an original and blackened by using a area which is reckoned as white by a reckoning mean as a frame erasing area. CONSTITUTION:An image sensor 1 scans an original by one line every time a horizontal synchronizing signal is received and outputs a picture signal proportional to the light quantity. The picture signal is corrected by a shading correction circuit 2, and a binarizing circuit 3 changes the white level and the black level of the binary signal data into '1' and '0' respectively. The binary data is inputted to a shift register 5 and an AND gate 6 outputs 1 when all outputs of the register 5 are equal to 1. An F/F 7 is cleared by a clear signal right before a reading action of one line starts. The output Q is kept to '1' before the white data is read in 8 continuous picture elements. Thus the output of an OR gate 8 is set to '1'. In such a way, a reckoning means I reckons all areas as white before 8 continuous picture elements are white from the beginning of the main scan of a read area. Then these areas reckoned as white can be used as the frame erasing areas.
