Abstract: A novel copolycarbonate is provided, which comprises recurring units respectively of the formulae:
      in a molar ratio of units (A) to units (B) of from 9:1 to 1:9. The copolycarbonate has a number average molecular weight of from 300 to 50,000. The copolycarbonate is useful as a reactive polymer for producing final polymers such as a polyurethane and a thermoplastic elastomer. The copolycarbonate as well as various final polymers produced therefrom have excellent resistance to hydrolysis, light, chlorine, oxidative degradation, heat, etc. The poly­urethane and the thermoplastic elastomer containing units of the novel copolycarbonate as soft segments exhibit remarkably improved flexibility and elastic recovery as compared to those of the conventional polymers.

Abstract: The invention concerns a procedure for the bleaching of pulp using an oxidating bleaching chemical containing chlorine. The essential features of the invention are that the chemi­cal used in the oxidation stage has a chlorine dioxide con­tent of at least 50 %, that the pulp is subjected to enzyme treatment either in conjunction with or before the oxida­tion, and that, after the oxidation and enzyme treatment, the pulp is treated with an alkali. The use of enzymes re­duces the amount of chlorophenols and other forms of organi­cally bound chlorine in the spent bleach liquor, simulta­neously lowering its chemical oxygen demand.

Filed: 1989-12-28
Abstract: A pressure control system for suspension delivers a pressure which is proportional to a current level chosen to energize a solenoid of a pressure control valve to a shock absorber of a suspension. A change in the pressure of a return path which supplies a low pressure to the pressure control valve causes the pressure which is applied to the suspension to change. In order to suppress such change, a junction of the pressure control valve with the return path has an orifice interposed therein or is connected to a low pressure accumulator. On the other hand, in the event a depression occurs in the output of the high pressure piping, a cut valve which functions to isolate the suspension from the pressure control valve may be temporarily cut off in response to a pressure fluctuation in the high pressure piping. In order to prevent this, an orifice is interposed between the high pressure piping and a pilot chamber of the cut valve.

Abstract: An image processing apparatus of this invention is arranged so that a threshold for use in binarization is switched between two types in accordance with whether or not a portion in which input pixel data is located is positioned in the vicinity of an edge portion of an image. One type is a threshold which varies in the width of variation corresponding to the density of the input pixel, while the other type is a fixed threshold. If an objective pixel is located in the vicinity of an edge portion of an image, binarization is carried out with the fixed threshold, while if the objective pixel is located in a non-edge portion, the variable threshold is used.

Abstract: An electronic postage meter 10 has two non-volatile memories 104, 106 for storing postage meter accounting data under control of a CPU 50 operating under a program in ROM. An accounting data recovery routine is stored in ROM. Prior to updating critical information in the non-volatile memories, a recovery address which calls the recovery program is stored in NVM and cleared after a successful update. At each power-up of the meter, the non-volatile memory is checked to see if the address is present and if it is, the accounting data is done again from the start of the accounting cycle.

Abstract: A pair of wiper blades (11,14) on a vehicle window (10) are oscillated in opposing movement between an overlapping inner wipe arrangement, in which one of the wiper blades overlaps the other, and separated outer wipe positions (31,36). In dynamic symmetrical overlap (DSOL) operation, the first wiper blade during each cycle to reach its outer wipe position is brought back first to be overlapped by the other for the start of the next cycle. This will normally produce alternating symmetrical overlap (ASOL) operation with its advantages of lower maximum blade acceleration and stress, since the overlapping wiper blade precedes the other on the way out. However, if the leading wiper blade is occasionally slowed, the other wiper blade will not be forced to wait in its outer wipe position; and the cycle time will be minimized.

Abstract: The architecture of a communication network comprising a plurality of nodes interconnected by a transmission facility having a bandwidth divisible into channels of respective bandwidths, e.g., optical fiber, is enhanced by fully sharing the network bandwidth among the network nodes, such that each pair of nodes, on periodic basis, dynamically establishes respective direct links to each of the other network nodes, in which a direct link is formed from a group of channels obtained from the network bandwidth. The remaining bandwidth is then used to form a pool of bandwidth which is shared among the network nodes on a dynamic basis, such as, for example, establishing a communication path between a pair of nodes to route a call from one node to the other node of the pair of nodes.

Abstract: A method for use in a high-speed virtual circuit digital network for resizing windows of virtual circuits in nodes of the network. The resizing of a virtual circuit's window is initiated by an input router at an edge of the digital network. When the input router determines that resizing is necessary, it sends a first congestion control message to the nodes through which the virtual circuit passes. If the message indicates a larger window, the node receiving the message determines what size window it can provide and sends the message with that window size on to the next node. An output router at the other edge of the digital network receives the message, sets the window size based on the message as altered by the nodes, and returns a second message with the final window size via the nodes. On receipt of the second message, the nodes alter their windows and the input router sends cells as permitted by the new window. Included in the method are novel techniques for determining the ideal window size for a virtual circuit, for determining at the input router when a change in
