Title: Surface coating containing al-base alloy and method for its manufacture
Inventor: MISHIERU PIERANTONI
IPC: C22C21/02
Filed: 1989-06-28
Abstract: A substrate (1) based on aluminium (Al) has a surface coating of the Al and silicon (Si) and at least one element X from the group comprising iron (Fe), nickel (Ni), cobalt (Co) or manganese (Mn), where the total content of the elements X can amount in total to 1-35% by weight. Depending on the concentration (C) of the elements X in % by weight, the surface has a minimum hardness measured in HV 0.05 and calculated according to the equation:  HV 0.05 = 134 + 2.6 x C + 0.44 x C<2>  on at least 50% of its coated area. The mechanical and/or chemical properties of the substrate (1) are sharply improved by the surface coating having the required minimum hardness. <IMAGE>

Title: Information processing system inverting and using memory
Inventor: SUZUKI OSAMU
IPC: G06F11/10
Filed: 1980-11-28
Abstract: PURPOSE:To improve the reliability of the whole operation by storing a bit, obtained by an exclusive OR operation an invert bit and a previous parity bit,  and the inverted bit of a memory in a degeneration fault and by inverting them  in readout operation. CONSTITUTION:For writing from a write data register WOR to a memory MM, an invert bit IB and a previous parity bit PB and exclusively ORed and the result is stored in the memory MM. When the contents of the memory MM are transferred to a read data register RDR, party checks on a data bit DB and a parity bit PB are made. In this case, when the stored position of the bit IB in the memory degenerates to 0 and the storage location of the bit PB degenerats to 0, the same value with the memory MM is stored in the register RDR because an inverting circuit does not operate. The parity check results in a parity error in this case and a defective invert bit is detected.

Title: Differential device
Inventor: YAMAZAKI SHINJI
IPC: F16H48/38
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a smooth differential limiting characteristic by preventing pulsation of discharge pressure of a gear pump by adjusting a phase of the discharge pressure between at least two sets of the gear pumps and preventing synchronization of discharge pressure variation. SOLUTION: Differential action of a differential mechanism 45 is limitted by frictional resistance of pumping work of each of gear pumps 53 which becomes larger as the number of differential rotation increases and a multiple disc clutch 49, and a differential rotational speed sensing type differential limiting function is provided. The number of teeth of a sun gear 65 constituting each of the gear pumps 53 is an odd number. Conversely, pinion gears 67 used in four pieces (even number) are arranged with equal intervals with each other. Consequently, engagement and disengagement of the sun gears 65 and the pinion gears 67 are carried out at different timings between each of the gear pumps 53, and synchronization is prevented. Accordingly, a phase is adjusted so that variation of discharge pressure does not synchronize between each of the gear pumps 53.  It is possible to provide a smooth and stable differential limiting characteristic as pulsation is not generated in differential limiting torque.

Abstract: PURPOSE:To eliminate damage due to wrinkles and jams of transfer paper, and to simplify mechanism and reduce the cost by providing a guide wheel capable of rolling and oscillating at at least one position between a conveying rack for transfer paper and a fixation part. CONSTITUTION:A crank arm 12 is energized clockwise through the operation of a torsion spring 14 wound around its base part to abut on a stopper 15. In this state, the guide wheel 11 is applied with energizing force enough to support thin transfer paper P1 which is used in general, thereby bringing the front end of the transfer paper P1 into contact with the peripheral surface part of a fixing roller 8a. When thick transfer paper P2 is used, on the other hand, the crank arm 12 rotates counterclockwise with the weight of the transfer paper to lower the guide wheel 11, and the spring constant of the torsion spring 14 is so selected as to perform switching to an angle at which the front end of the transfer paper P2 is brought into contact with the clamping part of a roller couple directly. Therefore, wrinkles and jams of the transfer paper are prevented, and the mechanism is simplified and the cost is reduced.
