Patent JP-H0262537-B2 (JP)
IPC: C07C41/06
Filed: 1984-06-25
Abstract: Methyl t-butyl ether and methyl t-amyl ether are produced by reacting methanol with isobutene and isoamylene, respectively, at a total methanol/isoolefine mole ratio of 1-1.2:1 in a series of reaction stages such that in the first reaction stage, the total amount of olefin component is reacted with as much methanol as is required to ensure that the methanol/isoolefine mole ratio in the first reaction stage does not drop to less than 0.65:1, and that the methanol concentration in the effluent stream does not exceed 0.4% wt. The residual amount of methanol is then fed either all at once to another reaction stage, or in portions to several additional reaction stages.

Abstract: Controlled enzymatic treatment may be used to selectively degrade undesirable contaminants to a size or charge range which can be more readily removed by subsequent separation steps. Treatment is especially useful for purifying rDNA or monoclonal antibody culture products by using nuclease enzyme treatment to degrade undesirable residual nucleic acids to a molecular size or charge range sufficiently different from the product to be purified so that this difference can be exploited in a subsequent purification step (e.g. precipitation, size exclusion chromatography or ion exchange chromatography).
Patent JP-H0338638-B2 (JP)
IPC: G06Q30/06
Filed: 1981-09-11
Abstract: PURPOSE:To obtain materials for business to be utilized by detecting the number of coming customers, counting data on the number of customers every time the detection is performed and finding data on the number of costomer at prescribed time, and then recording the number of customers coming within a specified time. CONSTITUTION:A store is opened at, for example, 9 o'clock. Coming customers are detected by a sensor S2, whose output is supplied to a one-shot circuit 22 and an AND circuit 31. Once said customers are detected by a sensor S1, the output signal of the circuit 22 allows counters 4 and 6 to go up by one, sending a customer entry signal to a circuit 5. According to the counted value of the counter 4, circuits 8 and 5 operate. Each entering customer is detected by the sensors S1 and S2 successively, and while the signal of a circuit 21 decreases the contents of the counter 4 by one, the circuit 5 operates. A timing signal is inputted to a control circuit 10 and a delay circuit 11 one hour later, and the counted value of the counter 6 is written in a memory 13 as data on the number of entering customers between 9 and 10 o'clock. A clocking circuit 14 writes current time and the delay circuit 11 clears the counter 6. Said operation is carried out repeatedly.

Abstract: A method and apparatus for testing very large scale integrated circuit devices, most particularly Level Sensitive Scan Design (LSSD) devices, by applying differently configured sequences of pseudo-random patterns in parallel to each of the input terminals of the device under test, collecting the output responses from each of the output terminals in parallel, combining these outputs to obtain a signature which is a predetermined function of all of the sequences of parallel outputs and comparing the test signature with a known good signature obtained by computer simulation. The input test stimuli are further altered in a predetermined fashion as a function of the structure of the device to be tested, to individually weight the inputs in favor of more or less binary ones or zeros.

Abstract: A brake ring for brake disks, especially disk brakes for rail vehicles, consisting of two annular bodies (2, 3) arranged adjacently at a distance from each other, having stud bolts (7) bridging the distance and rigidly connected with the annular bodies (2, 3). These stud bolts are so arranged, for the purpose of the most even distribution possible, that their axes (8) extend through the intersecting points of three systems of straight lines (9, 10 and 11) extending in one radial plane. The straight lines of the first system (9) are parallel and are at an equal distance from each other, the second system of straight lines (10) is formed by a rotation by 60 DEG  and the third system of straight lines is formed by a rotation by 120 DEG  of the first system of straight lines (9). Preferably, the ratio of the distance (A) of the stud bolt axes (8) and the diameter (D) of the stud bolts (7) is approximately 1.7. The brake ring has only minor aeration losses but high heat transmission by cooling air. When the brake ring heats up, the stresses within the annular bodies (2, 3) and the stud bolts (7) are evenly distributed, and the risk of fracture is reduced.

Abstract: Compositions hardenable by exposure to heat or electromagnetic radiation are provided by dissolving together to form a blend from about 0% to about 50% by weight of an uncrosslinked polymer, from about 2% to about 30% of a polymerizable monomer, from about 10% to about 70% of a crosslinked polymer in the form of discrete particles having average diameters of from 0.001 micron to about 500 microns and being swollen in said solution and from about 20% to about 70% of a crosslinking agent for said monomer. Such compositions exhibit superior chemical and physical characteristics when hardened and are suitable in a wide variety of applications as construction media. Such compositions are especially suitable in the production of prosthetic dental appliances, such as, for example, prosthetic teeth. It is believed that the hardening of such compositions as, for example, during the preparation of dental appliances forms a polymer system known as an interpenetrating polymer network.

Abstract: A surgical stapling instrument for stapling a tubular tissue structure having at least one distal end to a luminal structure, such as a vascular lumen or another tubular tissue structure. The instrument comprises a rod having a circumference sufficient to pass within the tubular tissue structure, an anvil mounted on the rod, and a generally tubular staple cartridge for containing a plurality of staples. The anvil has an array of staple deforming theron and is of a size sufficient to pass through a sugically formed opening in and to be accommodated within the luminal structure. The inner passage of the staple cartridge is sufficient to axially accommodate the tubular tissue structure between the rod and the inner surface of the staple cartridge, and sufficient to allow the staple cartridge to be moved axially along the rod. The staple delivery end of the staple cartridge is positioned toward the staple deforming of the anvil and has an outer dimension small enough so that the tubular tissue structure can be everted thereover. A clamping mechanism secures the everted portion of the tubular tissue structure and the luminal structure adjacent to the sugically formed opening between the staple cartridge and the anvil. A plurality of staples may then be ejected to pass through the everted portion of the tubular tissue structure and the luminal structure to engage the staple deforming to deform the staples and create a bond between the tubular tissue structure and the luminal structure. The staple cartridge and/or anvil may be configured to provide a non-circular anastomotic connection having more natural, less turbulent blood flow therethrough.

Date May 7, 1987.The invention relates to a multi-ply wood product. The supply of wood suited e.g. for the production of plywood has considerably decreased. Consequently, attempts have been made to compensate the deterioration in the quality of the surface finish and in other wood qualities e.g. by means of various coating methods, with varying success. The most important problem has been the insufficient adhesion between the coating and the wood. For the elimination of these problems, a multi-ply wood product has been developed in which at least one layer is formed by a crude fiber ply blank comprising haphazardly oriented fiber material as well as bonding agents, additives and filler materials. A single hot-pressing step in connection with the production of the multi-ply wood product forms this blank into homogeneous ply (14) which, by virtue of the partial splitting of the fiber structure and the resulting reorientation, which take place during the hot-pressing, fills the irregularities in the surface of an adjacent wood layer (1) and forms a tight synthetic ply of accurate dimensions.
