Abstract: A method of producing a ceramic diaphragm structure (2) including a ceramic substrate (4) having at least one window (6), and a ceramic diaphragm plate (8) which is superposed on the ceramic substrate to close the window or windows. The diaphragm plate includes at least one diaphragm portion (10) which is respectively aligned with the window(s), and each diaphragm portion protruding outwards, in a direction away from the corresponding window, to form a convex shape. According to the method of the present invention, a jig (14, 15, 22, 23) having a flat surface or a concave surface is pressed against a top part of each diaphragm portion (10), during or after formation of the convex shape of the diaphragm portion, so that at least the top part has a flat surface (10a) or a curved surface (10b) having a predetermined radius of curvature, thereby to control an amount of protrusion of the diaphragm portion.

Abstract: Increased numbers of multipath transmission errors, that are detected by the performance of cyclic redundancy checking (CRC) over time and frequency on the words of a multitone transmission block that include mapped information bits, are correctable by forward error control as a result of the iterative performance of CRC over frequency on subblocks of the transmission block using retransmitted parity checking bits. A continuous record is maintained of the frequency channels that are detected as experiencing transmission errors in order to maximize nthe rate of data bit transmission on frequency channels that are likely to experience a reduced number of transmission errors.

Abstract: The package bearing (A) for coupling a road wheel (C) to the suspension system of an automotive vehicle includes a nonrotatable outer bearing ring (12) having flanges (20) along which it is attached to the suspension system, a rotatable inner bearing ring (14) located within the outer ring (12) and having a flange (72) to which the road wheel (C) is attached, and tapered rollers (16, 18) arranged in two rows between the outer and inner rings (12, 14). The rollers (16, 18) contact the rings (12, 14) along inboard and outboard raceways (26, 28, 46, 48) that are likewise tapered, their large ends being at the ends of the two rings (12, 14). The large ends of rollers (18) on the outboard row move along a rib at the flange (72) on the inner ring (14), while the large ends of the rollers (16) of the inboard row move along a rib ring (60) that is formed as a separate element and subsequently connected to one of the rings (12, 14). Between its inboard and outboard raceways (46, 48) the inner ring (14) has a cylindrical intervening surface (50), the diameter of which exceeds the largest diameter on the inboard raceway (46) of the inner ring (14). This enables an encoder ring (52) to advance over the inboard raceway (46), and to be pressed over the intervening surface (50) to its final position. Thereafter the rib ring (60) is secured against one of the rings (12, 14) at the large end of the inboard raceway on that ring. During assembly, the rollers (16) of the inboard row are likewise advanced over the large end of the inboard raceway (46) for the inner ring (14), all while confined in a cage (94) - but the cage (94) has breaks in its small end ring to enable it to expand and accommodate the large end of the raceway (46). The outer ring (12) carries a sensor (34) which monitors the encoder ring (52), producing an electrical signal, the frequency of which reflects the angular velocity of the encoder ring (52). Seals (96, 98) close the annular space between the bearing rings (12, 14) at the inboard and outboard ends of the rings (12, 14).

Abstract: An FM broadcasting signal carrying multiplex character data transmitted from a radio broadcasting station is automatically preset in an FM receiving apparatus. An FM broadcasting signal is received, and a frequency information of the received FM broadcasting signal is temporarily memorized in a memory (20). It is judged whether a PLL lock signal is produced by a clock signal reproducing circuit (24) during a demodulation process of the FM broadcasting signal whose frequency information is memorized in the memory (20). When it is determined that the PLL lock signal is produced by the clock signal reproducing circuit (24), it is determined that the FM broadcasting signal carries multiplex character data, and the frequency information of said FM broadcasting signal is preset to the FM receiving apparatus.

Title: Word-wise processing for reed-solomon codes

IPC: H03M13/00

Abstract: A word-wise encoder circuit that processes word formatted data blocks in response to a word clock signal and generates redundancy in accordance with an 8 bit symbol code. The encoder is provided with two parallel data paths, each receiving one of the respective bytes halves of the received data words during one word clock period to implement an 8 bit symbol code in response to a word clock signal. The word-wise encoder replicates, in one word clock period, the state of the registers in a standard sequential encoder after two consecutive bytes have been processed in response to a byte clock. In a preferred embodiment, a word-wise encoder is used to implement a Reed-Solomon data integrity code. In this example, the word-wise encoder generates redundancy that is appended to associated data blocks temporarily stored in a block buffer memory within a data channel to provide a mechanism for detecting data errors caused by the buffer. A reduced hardware implementation of a word-wise encoder circuit is disclosed wherein a special choice of generator polynomial and Galois field representation allows a Galois field multiplier to be eliminated. In this embodiment, the encoder generates two bytes of redundancy per data block and the longest propagation path in the encoder traverses one multiplier and two adders. <IMAGE>

Abstract: In a separator for separating a stripping sheet from a composite film formed by a base sheet and the stripping sheet which are superposed with each other, the composite film is first so carried and arranged that its forward end portion extends over a separating clearance formed in a support, and then a blade is pushed into the separating clearance for thrusting the composite film into the separating clearance in a bent state. Thus, the forward end portion of the composite film is separated. Thereafter the base sheet and the stripping sheet are independently sucked/held on the separated forward end portion, and the stripping sheet is completely separated from the base sheet while widening the space between the held positions of these sheets. Due to the aforementioned structure and operation, the composite film can be separated in a simple structure with minimum force, and the separator can be reduced in size and power.

means to the first position when a level in the soil water
basin (1) reach a predetermined level, and means for urging
