Abstract: A magnetic head inserting hole (6) is provided in the side face (4) of a fla t cassette shell (2) comprising a top face (21), a bottom face (22), and side faces (23). A shutter member (8) is slidably provided and constituted integrally of an upper sleeve section (81), a shutter section (82), and a lower sleeve section (83) which extend respectively along the top side, and bottom faces (21, 4, and 22) of the shell (2) in such a way that the member (8) has a U-shaped cross section and opens/closes the holes. A plate-like member, to be bent into the shutter member (8), has an opening (82a) whose size is wider than the width of the shutter member (8) defined by the bendin g lines A by a length which is three or more times the thickness of the plate- like member. Therefore, the opening (82a) extend to the upper and lower slee ve sections (81, 82) after the shutter member (8) is formed. Thus, the shavings  from the cassette shell (2) are not produced when the shutter opening (82a) is deformed at the time of bending the plate-like member into the shutter membe r (8) and the member (8) slides smoothly.

Abstract: A collagen is extracted and produced from a raw fish skin through the steps: a salt admixing step for admixing a salt (e.g. NaCl, KCl or the like) with raw fish skin so as to allow non-collagen substances or portions (including fats and tissue portions other than collagen portions) to be removed from the fish skin, while simultaneously degreasing and deodorizing the skin under the salt effect; a salt removal step for causing the admixed salt and non-collagen substances or portions to remove from the skin, achieving the fats removal and deodorization; a collagen extraction step for extracting a collagen (gelatinous) from the this-treated skin; and a filtration step for filtering and refining the extracted collagen so as to obtain a refined collagen. The refined collagen may be dried and solidified. Thus, since inexpensive salt is used for effective removal of non-collagen substances or portions to obtain a collagen portion, the method itself is simplified and economical. Further, the fish collagen obtained thereby, be it fluid or dried, is of a highly refined property, i.e., colorless, odorless and degreased, which is suitable for food product elements and various industrial uses.

Abstract: The need in the art is addressed by the hard-target penetrating warhead of t he present invention. In the illustrative embodiment, the inventive system is adapted for use with length constrained missile payload bays and includes a warhead case for containing explosives. A tungsten ballast is inserted within the case to provide a high warhead sectional pressure upon impact of the missile against a target. A fuse detonates the warhead explosives following penetration of the target. A fuse well houses the fuse and is attached to the case at one end. A slip fit section of the fuse well provides structural support to the case an d prevents dislodging of the fuse well and the fuse from the case upon missile target impact. Explosives blowout ports included in the fusc we ll inhibit undesirable detonation of the warhead explosives by accidental exposure to high heat. In a specific embodiment, the case include s a 6 caliber radius head nose. The fuse well includes main explosives blowout ports for allowing accidental exposure to high heat to bu rn the missile explosives and safely vent gases resulting from the burning. The main explosives blowout ports are placed around a circumference of the fuse well and include nine ports having a surface area designed to prevent undesirable detonation. The blowout ports alsoinclu de booster blowout ports for allowing safe venting of booster charge explosives that are included in the fuse. Additionally, a special polyethelene/polyalphaolefin liner lines the inside of the case for improving safe venting performance under fast cook-off hazardous conditions. The warhead explosives include PBXN - 109. The case includes a textured or lightly grooved surface for facilitating bonding of t he ballast to the case.

Abstract: An apparatus and method are used to modify the surface chemistry of an article. The article to be surface treated has at least a surface region that includes at least one polymer. The method comprises the steps of placing one or more articles into a closed reaction chamber which is evacuated to a negative pressure. After evacuation, a treatment gas is rapidly injected into the reaction chamber, the treatment gas having an essentially predetermined composition comprising one or more components which are reactive with the articles within the reaction chamber. The treatment gas is allowed to react with the articles within the closed reaction chamber for a predetermined period of time. The treatment gas is then removed from within the reaction chamber and replaced with an inert gas at about atmospheric pressure. Finally, the treated articles are removed from the treatment chamber.

Abstract: A dirt cup latching mechanism that secures a lid onto a dirt receptacle of vacuum cleaner and simultaneously secures the dirt cup in place on the vacuum cleaner. The latching mechanism presses the lid down onto an open top of the dirt receptacle and presses the dirt receptacle down into a dirt cup retaining recess provided in a generally horizontal wall of the vacuum cleaner housing. The latching mechanism may press down on the top of an open topped dirt receptacle, with or without a lid, while simultaneously pulling the dirt cup horizontally against a generally vertical wall of the vacuum cleaner housing. Thus, the latching mechanism simultaneously presses the dirt receptacle down against one of an inlet and outlet seal located on the horizontal wall of the housing and horizontally against the other one of inlet and outlet seal on the vertical wall of the housing, thereby sealing both the receptacle inlet and outlet.

Title: Improved des and other cryptographic processes with leak minimization for smartcards and other cryptosystems
Inventor: JAFFE JOSHUA M
IPC: H04L9/06
Filed: 1999-06-03
Granted: 2005-05-10
Abstract: Methods and apparatuses are disclosed for improving DES and other cryptographic protocols against external monitoring attacks by reducing the amount (and signal-to-noise ratio) of useful information leaked during processing. An improved DES implementation of the invention instead uses two 56-bit keys (K1 and K2) and two 64-bit plaintext messages (M1 and M2), each associated with a permutation (i.e., K1P, K2P and M1P, M2P) such that K1P {Kl} XOR K2P {K2} equals the "standard" DES key K, and M1P {M1} XOR M2P {M2} equals the "standard" message. During operation of the device, the tables are preferably periodically updated, by introducing fresh entropy into the tables faster than information leaks out, so that attackers will not be able to obtain the table contents by analysis of measurements.      The technique is implementable in cryptographic smartcards, tamper resistant chips, and secure processing systems of all kinds.
