Title: Roll coolant skimming device
Inventor: OHARA TAKESHI
IPC: B21B27/10
Filed: 1993-06-15
Abstract: PURPOSE:To automatically remove the scum in a coolant tank with good efficiency in a short period of time with the device for removing the scum (floating foreign matter, waste oil, etc.) of the skimming device for a roll coolant equipment of rolling mills. CONSTITUTION:Operating procedures for skimming are previously inputted to a control panel 20. The liquid level A in a dirty tank and the liquid level B in a clean tank are detected by liquid level transmitters 39, 39 and are subjected to comparative computation in the control panel 20, which in turn regulates the liquid level A in the dirty tank up to an overflow level to the prescribed weir part 5a of a scum discharging trough 5. A chain 12 of the skimmer 10 is then rotated and plural water raking plates 11 thereof are moved toward the scum discharging trough 5, by which the scum floating on the liquid surface is poured and discharged into the scum discharging trough 5.

Title: Through-hole filled ceramic substrate and conductor paste for through hole
Inventor: MORI MAMORU
IPC: H05K3/46
Filed: 1993-06-14
Abstract: PURPOSE:To improve the reliability of connection with a substrate wiring, reduce resistance, and prevent cracks from being generated even if a clean sheet is laminated by containing a conductor powder selected from silver or copper and a specific amount of ruthenium oxide powder to the powder. CONSTITUTION:A conductor paste is filled into a through hole 1 of a ceramic substrate 2 for use. By adding ruthenium oxide powder to a conductor powder selected from silver powder or copper powder, a conductor paste with a small baking shrinkage rate can be obtained. Even if the amount of added ruthenium oxide increases, the baking shrinkage rate is nearly equal to zero and does not change but conductor resistance increases since the amount of conductor powder within the conductor paste decreases relatively. The amount of added ruthenium oxide powder should be 0.1wt.% or larger (preferably, 0.1-15wt.%). Therefore, since the inside of the through hole 1 is filled with conductor paste, a reliable wiring without any crack and disconnection can be constructed on a green sheet 5.

Filed: 1987-07-07
Abstract: PURPOSE:To scale down a device and to uniformize an exposing amount of luminous energy by providing a beam reflecting means which reflects plural laser beams in different directions and exposes beams in different positions in the sub-scan direction of an object to be scanned. CONSTITUTION:The laser beams LA and LB emitted from a laser 1 are exposed and scanned on a photosensitive body 3 as an object to be scanned by a polygon mirror 2 (deflecting means) as a polarizing means. Points A and B where the laser 1 emits light can be independently controlled in terms of their light quantities, which can be modulated according to different pieces of graphic information. The laser beams LA and LB reflected by reflecting faces of a prism-like mirror (beam reflecting means) are oriented toward the photosensitive body 3 through bending mirrors 8a and 8b. Images can be formed in a position away from the subscan direction of the photosensitive body 3 by cylindrical lenses 9a and 9b so that the prism-like mirror 7 and the photosensitive body 3 are in conjugate relationship. Thus the device can be scaled down, and unevenness of the exposing amount of luminous energy can be eliminated.

Title: Cell
Inventor: AMEZUTSUMI TORU
IPC: H01M6/16
Filed: 1986-07-17
Abstract: PURPOSE:To prevent from breaking a separator by a core body even though an external force brings a remarkable to a cell, by using a heat-resisting resin film with an electron conductive layer formed on its surface as the core body. CONSTITUTION:A manganese dioxide positive electrode plate 10 and a lithium negative electrode 12 both with a core body 11 are wound through a separator 13 to form a spiral electrode body. As a core body 11, a resin film 11a consisting of polyimide with electron conductive layers 11b over the both surfaces is used. Since the core body 11 has a good extending property by using the resin film 11a as its base, an external force can hardly cut off the core body 11, and even though the core body 11 is cut off, the separator 13 shall not be broken by the cut off top. Furthermore, even though the separator 13 is broken by some other cause and the core body 11 contacts the opposite electrode, a permanent contacting condition can be avoided.

IPC: B41J2/44
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain a detection signal at arbitrary timing as required. SOLUTION: A photosensitive drum 4 is electrified when the preparation of an optical system is completed so as to form an image on the photosensitive drum 4 by sending a video signal from an image controller in synchronous with a horizontal synchronizing signal sent from a printer control circuit for turning ON/OFF a laser driving signal in order to transfer the image on a paper for fixing a toner image. During the formation of the image, a synchronizing light sensor 32 detects the horizontal synchronizing signal sent from a polygon mirror 31. When no horizontal synchronizing signal is detected at the timing due to the stable rotation of a scanner motor, a compensatory signal forming circuit 33 outputs a compensatory signal so as to continuous the controlling of the scanner motor.
