Filed: 1988-11-18
Abstract: PURPOSE:To early detect the malfunctions due to the address change given to a memory element by performing the comparison between the output signal of a parity circuit to be applied to an address register and the read data output signal of the memory element when the data is written to the memory element. CONSTITUTION:The output of an address register AR 2 which supplies an address AD to a memory element 1 is supplied to the element 1 as an AD input signal and also serves as the input signal of an AD parity generating circuit PG 3. A read data register RDR 4 receives the read data under the control of a selection circuit 12 and then receives the parity signal of a signal AD at write. A comparator 5 compares the parity signal of the AR 2 set at write with the AD parity signal which is read out of the element 1 and sent to the RDR 4. If no coincidence is obtained between both parity signals, an error signal is outputted to recognize that an error is included in an AD input circuit of the element 1 including an AD supply route led from the AR 2.

Title: Fiber reinforced resin roller and manufacture thereof
Inventor: NAKAMURA HIROSHI
IPC: F16C13/00
Filed: 1992-10-30
Abstract: PURPOSE:To facilitate conveyance because of lightweight, enable driving in low torque, endure high speed operation, improve productivity, and contribute to reduction of labor by coating the surface of an FRP roller element pipe with a fluorocarbon resin particulate contained complex metal layer. CONSTITUTION:A proper backing layer is arranged on the surface of an FRP (fiber reinforced resin) roller element pipe, and next, fluorocarbon resin particulate contained electroless complex plating is applied. When the electroless complex plating is applied, roller accuracy such as circularity or straightness of the FRP roller element pipe (after the backing layer is applied) is finished beforehand by grinding or polishing or the like, and afterwards, the fluorocarbon resin particulate contained electroless complex plating is applied. Since a coat of the electroless plating is adhered uniformly to the surface without causing nonuniformity of a place, it has an advantage that a process such as machining by a lathe after the metal plating can be omitted or a process such as grinding can be omitted when occasion demands. Desired surface roughness can be obtained by carrying out surface polishing finish simply according to its necessity.

Abstract: PROBLEM TO BE SOLVED: To stop a moving device by moving by a desired quantity in the desired direction with high accuracy by providing a driving means for driving them in the mutually crossing X, Y axis direction when a support plate and a base member float and driving itself in the X, Y axis direction when they do not float, on the under surface of the support plate. SOLUTION: An X, Y axis driving device 30 is arranged on the inside of a base member 10 and on the under side of a support plate. Here, the whole weight of the base member 10, the support plate and a gear measuring device being a loading object is set to almost 500 kg, and weight of only the X, Y axis driving device 30 is set to about 20 kg. Then, when actuating stepping motors 36, 44 without floating the base member 10, since the weight of the X, Y axis driving device 30 is fairly smaller than the total weight, the X, Y axis driving device 30 itself moves. Thus, after moving the X, Y axis driving device 30, the base member 10 is floated, and the X, Y axis driving device 30 is driven so that a moving device can be stopped by moving by a desired quantity in the desired direction with high accuracy.
