Abstract: A female connector housing 11 has a locking arm 30 integrally moulded thereon, the locking arm 30 having a fitting projection 31. A male connector housing 21 has a fitting hole 24 formed on hood member 22 thereof. Two slots 34 are formed on either side of the fitting projection 31 so as to extend along the longitudinal direction of the locking arm 30. The locking arm 30 is thus partitioned into a fitting arm member 35 which includes the fitting projection 31, and two supporting arm members 36 which are formed on both sides thereof. The foot members 36a of the supporting arm members 36 are thicker than the foot member 35a of the fitting arm member 35, and thus the engagement load of the arm 30 is large, but the projection 31 is nevertheless relatively easy to disengage.

Abstract: A method is disclosed whereby a high performance, high integrity, cryptographically secure sequence generator based on zeta one-way functions is specified for pseudorandom sequence generation, authentication, key transfer by public discussion, and message transmission by public-key encryption. The method encompasses a new one-way function with trapdoor based on Artin reciprocity in an algebraic number field. Public keys are pseudorandom sequences based on zeta one-way functions. In the simplest instance of this method, public keys are quadratic signatures, i.e. special sequences of Jacobi symbols. The generation, transfer, and sharing of private keys is a process based on the law of quadratic reciprocity. The computational complexity of the quadratic signature problem provides the foundation for the cryptographic security of this method. This new trapdoor one-way function is distinct from constructions in the prior art.

Abstract: A synchronization equipment performs correlation processing between a first known pattern included in a received signal and a second known pattern, and detects reception timing of the received signal. A correlation value computing portion (3) computes a correlation value between the first known pattern and the second known pattern at every reception time. A reception timing detection portion (108) compares the computed related value with a predetermined threshold value, determines the reception time when the correlation value becomes larger than the threshold value to be the reception timing of a received signal, and, after this determination, suspends the comparison between the correlation value and the threshold value, and holds the reception time determined to be the reception timing.

Abstract: The baffle pot in the fuel tank forms the accumulator whose capacity is limited by a spring-loaded (10) piston (11), using a piston travel switch (12) in a pot as a pressure switch. The accumulating space (9) is connected to the fuel delivery line (7) from pump to distributor bar by an electrical cutoff switch (13), and the piston spring (10) coaxially surrounds the fuel pump (1). Baffle (2), pump and accumulator space (9) are joined to one another in modular arrangement, screwed together by tie-bolt screws, and installed all together in the baffle pot. Fuel is passed from pump and reducer via line (21) and switch (13) to the accumulating space (22), so when the piston moves against its spring the fuel line pressure exceeds that imposed by the reduction regulator to build fuel at working pressure on the bar (7). At capacity, piston moves the switch (12) into the open setting thus de-energising the pump until the accumulator capacity is sufficiently lowered and the fuelling cycle recommences.

Abstract: A system and method of printing value such as postage using a value meter (10) connectable to communicate with a host terminal (12) which includes a printer (24). The postage meter (10), sometimes referred to as a vault, includes a processor (14) and storage (16) and the host terminal includes a processor (22) and storage (30). The printer (24) is provided with a secure non-volatile random access storage (30) and a processor (28) and a key is stored in the non-volatile random access storage (30). The key is changed for every print cycle so that it is impossible to print unauthorized postage on the basis of possession of the key used to print the last postage. A change of key is effected by reading the key from the non-volatile random access storage (30) in the printer (24) and changing the key, such as by a pseudo-random number generator, to provide a second key. The second key is stored in the non-volatile random access storage (30) and then encrypted by an encryption scheme known to an authorized postage meter. The encrypted second key is transmitted to an authorized postage meter wherein it is decrypted pursuant to the decryption scheme known to the authorized postage meter. Print data may be securely transmitted to the host (12) and printer (24) by using the decrypted second key to convert the data to be printed. This is then sent to the printer where it is deconverted using the second key to recover the data to be printed.

Abstract: A compressor has a front housing(11), a cylinder block
(12) and a rear housing (13). The housings (11, 13) and the
cylinder block (12) are secured to one another by a
plurality of bolts (62; 65). A plurality of pistons (32)
reciprocally move in cylinder bores (31) to compress gas.
Each of said bolts has a shaft extending through the
housings and the cylinder block. A cam plate (21) is
supported on a drive shaft (16) for integral rotation
therewith to convert the rotation of the drive shaft to
reciprocal movement of a piston in the cylinder bore. The
piston rotates about its axis in accordance with rotation
force transmitted from the cam plate and abuts against the
shaft of the bolt, which extends in close proximity to the
piston. The rotating piston abuts against the shaft so that
the rotation thereof is restricted. The shaft has a
diameter greater than that of a threaded portion formed at
an end of the bolt. Since the threaded portion is smaller,
the threaded portion does no damage to the piston during
assembly.

Abstract: The present invention is a variable-delay division (VDD) scheme implementable in hardware to execute signed and unsigned integer division and remainder operations in digital processor. The VDD scheme advantageously uses hardware utilized for multiplication to implement a 2-bits/cycle alignment step to iteratively align the divisor with the dividend. This speeds up the alignment phase of integer division. Quotient bits are produced at the rate of 1-bit/cycle using the well-known restoring scheme. For 32-bit 2's complement operands, the scheme has a delay less than a fixed-delay scheme for most operands.

Abstract: Cable TV providers have an infrastructure which is well suited for providing additional services such as telephone and data connections to their subscribers. Techniques are disclosed for improving the error detection, masking, and avoidance capabilities of such a system. Because the system can distinguish telephony from data traffic, alternate error masking techniques can be employed for each type of traffic. An erroneous telephony packet, for example, can be replaced by silence, because the ear is relatively insensitive to short voids. Additionally, the links to the data or telephony provider can be maintained by the cable provider during interim noise periods. Because the network is structured as a multiple access network, and the likelihood of simultaneous upstream messages from all subscribers is low, error monitoring can be implemented on underutilized equipment to effect error avoidance, both as a preventive measure as well as a corrective measure.
