IPC: C22C47/00
Filed: 1989-04-27
Abstract: PURPOSE:To produce a fiber reinforced metal excellent in strength by smoothing the fiber surface of a preform composed of fiber reinforcement by means of chemical etching and then impregnating the above preform with molten metal. CONSTITUTION:A preform of fiber reinforcement is prepared by molding a heat resisting fiber reinforcement, such as fibers of Al2O3, SiC, and ceramics, by the use of a binder, such as PVA, and then thermally decomposing the binder. This preform is etched by using a chemically attacking solution, such as acid, alkali, and boiling water, by which cracks, flaws, etc., liable to cause fracture in the surface of the fiber reinforcement are removed to smooth the fiber reinforcement surface. Subsequently, the above preform composed of the fiber reinforcement in which strength is recovered is impregnated with molten metal. By this method, the fiber reinforced metal which consists of the smoothed fiber reinforcement free from surface damage and the matrix metal with which the above fiber reinforcement is impregnated and has superior strength can be obtained.

Title: Loop network transmission control system
Inventor: OKAZAKI HIROYUKI
IPC: H04L12/00
Filed: 1985-05-20
Abstract: PURPOSE:To avoid the increase in delay time of a packet exchange signal and an exchange control signal and complaints in call loss rate of a line exchange signal from being incurred by allowing a communication node to bring a slot number used for the line exchange signal after the next and succeeding frames into the regulating state setting a new call within a permitted range while communicating with a control node when the line exchange signal is in overload state. CONSTITUTION:In the unified exchange constitution for a line exchange signal and a packet exchange signal using a loop network, N denotes the total slot number of one frame, N1 denotes the 1st reference value and N2 denotes the 2nd reference value, then the total slot number used for the line exchange signal on a loop of each node increases gradually from a region (less than N2) with less total slot number and the connection of a call of the line exchange signal is brought to the regulating state when the number exceeds the number N1. Then each communication node communicates the control node for the slot number used for the line exchange signal and the regulating state setting a new call is brought within the permitted range. Even when the total slot number is reduced, so long as the number is the number N2 or below, the regulating state is not released.

Abstract: PROBLEM TO BE SOLVED: To record/reproduce a digital signal in a control circuit for recording/ reproducing an analog signal by converting the reference signal of a frame cycle into a field cycle by using the omission correction of a vertical synchronous signal and comparing the phase of the reference signal with that of the frequency-divided reference signal. SOLUTION: A synchronous signal outputted from a digital signal processing circuit 33 is supplied through a changeover switch 10 to a vertical synchronous signal detector 4. A digital signal inputted to a recording/reproducing amplifier 34 is passed through a magnetic head 1 and then recorded in a magnetic tape. A complement pulse generator 5 determines the omission of a synchronous signal because an output from the vertical synchronous signal detector 4 is longer than the cycle of a vertical synchronous signal and generates a complement pulse in a position of about 16.68 mS from the edge of a 30 Hz signal. The complement pulse is added to the output from the vertical synchronous signal detector 4 and then its result is added to a frequency divider 6, and then digital signal recording is performed.
