IPC: E02D31/06
Filed: 1986-12-29
Abstract: PURPOSE:To permit the centrifugal production of a cover by a method in which a partition formwork is interposed through a section profile between the adjacent molding plates of a formwork unit, after placing a hardening material, the hardening material and fibers are supplied while turning the formwork unit, and the molded object is removed and cut at a specific position. CONSTITUTION:A split cylinder-type formwork unit 4, consisting of a flange side, outer molding plates 1 and 2, and connecting metals 3, is set, where the metal tools 3 and a partition formwork 5 are connected with bolts 6 and the formwork 5 is interposed through a section profile 7 forming bolt holes between the adjacent molding plates 1. A hardening (with time) material 8 for flange is packed into the space formed by the formwork 5 and the molding plates 1 and compacted while turning the unit 4 and its supporter.

Title: Paper feeding unit
Inventor: MAEDA KATSUMI
IPC: B65H1/12
Filed: 1986-12-24
Abstract: PURPOSE:To feed paper in good conditions, by applying an application member being yet smaller in a friction factor to a paper feed roller in an image making device at a spot just behind a guide member out of a paper feed roller in a paper feeding unit, in case of a copying machine or the like. CONSTITUTION:Sheets S in a paper feeding unit 20 are pressed to a paper feed roller 30 by a pressing device 50, delivered from the topmost paper in order with rotation of the paper feed roller 30, and reached to another paper feed roller in a copying machine body 1 along a guide member 23. And, a tip of each sheet S is considerably weakened of its conveying force due to weakness in its own stiffness, but it is applied to the paper feed roller by a pressing plate 27, obtaining new conveying force, thus it is fed to a resist roller pair 19. Here, when two or three sheets are doubly delivered out of the paper feed roller 20, conveyance of the lower sheet S is prevented by a handling member 6, but it is actually checked by the pressing plate 27 beforehand. Thus, good paper feeding is performable and, what is more, a handling action at the time of double feeding is also made possible.

Filed: 1990-11-15
Abstract: PURPOSE:To improve the transmission efficiency of the entire network by providing a memory to store an initial value of a trial time number counter so as to calculate a back-off time from the initial value optimizingly at all times. CONSTITUTION:An initial value (n) is loaded to a trial time number counter 1 from a memory 3. The initial value (n) is set to the counter 1 as the count C and a back-off time is calculated. Then the content C of the counter 1 is incremented by one. A terminal equipment awaits its transmission till the back- off time elapses and then sends the packet again. When the re-transmission is successful, the content C is decremented by one and the result is written in the memory 3. When collision takes place, the initial value stored in the memory 3 is used as the count of the counter 1 and the back-off time is calculated.

IPC: F27B9/22
Filed: 1987-12-09
Abstract: PURPOSE: To make uniform the thermal hysteresis of an object to be treated and at the same time avoid a failure on a carrying path in advance by providing a control device for arbitrarily changing the drive speed of a pusher for carrying and at the same time stopping the pusher for carrying when a pushing resistance of the object exceeds a certain value. CONSTITUTION: An object to be treated is transferred to a carrying path in a reactor body 4 by a cylinder (pusher for carrying) 37 installed at the rear of a carry-in part 5. A motion that a rod in the cylinder 37 gradually advances at a specific speed and instantly retreats, is repeatedly operated instantly, and the rod moves the object to be treated on a tray T from an entrance to an exit in the furnace body 4 without any interruption, thus making uniform the thermal hysteresis of heat treatment and obtaining a product where the state of sintering treatment is homogeneous.  Also, when a plurality of trays are blocked due to some causes, the detected value of a pressure oscillator 37a for detecting the hydraulic pressure of the cylinder 37 increases as compared with a normal case and hence the operation of the cylinder 37 is stopped by a control device 37b, thus preventing the cylinder 37 from being overloaded in advance.

Abstract: PURPOSE:To prevent the intrinsic resonance of a movable member by balancing left and right inertial moments centering the hinge. CONSTITUTION:A supporting section 3 is joined to a galvanomirror base 2 fixed on a chassis base 1. A case 6 supporting an elastic and thin hinge 4 and a mirror 5 is extended to left and right centering the hinge 4 thereon. A driving coil 7 is wound the inside of the left and right hinges.
