摘要:
The present invention provides a novel compound having an excellent acetylcholinesterase inhibitory effect. That is, it provides a 4-substituted piperidine compound fluoride represented by the following formula, a pharmaceutically acceptable salt thereof or hydrates thereof (provided that 1-benzyl-4-[(5,6-dimethoxy-2-fluoro-1-indanon)-2-yl]methylpiperidine, a pharmaceutically acceptable salt thereof and hydrates thereof are excluded). wherein R1 and R2 represent substituents.
摘要:
Unreacted gas generated at outside is introduced through a gas inlet tangentially into a secondary combustion chamber with a substantially cylindrical side wall, so that a spiral ascending flow of the unreacted gas is generated in the chamber. A bulk material in the chamber is blown up by the unreacted gas introduced through the gas inlet to be circulated in the chamber so as to substantially completely burn unburnt solids entrained in the unreacted gas.
摘要:
High resolution vertical and horizontal components of a high definition video signal are combined with a standard broadcast system video signal, such as the NTSC system, in which high frequency horizontal resolution components are sampled and used to modulate at least a first sub-carrier signal. The first sub-carrier is frequency interleaved onto the standard broadcast signal. Vertical high resolution components are time compressed and time division multiplexed onto top and bottom portions of the standard broadcast signal. The modified broadcast signal can be decoded by a standard receiver to display a standard resolution video image, while receivers designed to decode the modified signal can time division demultiplex the vertical high resolution components and demodulate the horizontal high resolution components, combine these components with the standard components, and generate a high definition video image.
摘要:
A silicone putty composition having high impact resilience immediately after preparation and providing a soft silicone putty having low plasticity is obtained by blending (1) a diorganosiloxane of the formula:R.sub.n SiO.sub.(4-n)/2wherein R is a substituted or unsubstituted monovalent hydrocarbon group and n is a number of from 1.98 to 2.02, (2) an organopolysiloxane having a terminal alkoxy group, (3) boric acid or boron oxide, and (4) liquid paraffin. The composition is suited for use in toys and dampers.

An automobile headlamp system comprising a retractable headlamp which moves between its retracted position inside the body of an automobile and its protruded position. When the headlamp is in its retracted position, it is covered by a lamp over. When the cover is moved from its closed position to its open position, especially at the beginning of this movement, the rear end of the cover is shifted slightly forwards. Therefore, the lamp cover can be opened without interfering with the body of the automobile if the rear end portion of the cover is not straight but curved to a great extent.
摘要:
An up-link power from an earth station in a satellite communication system is controlled to compensate rain attenuation caused in an up-link so that the transmission power of the earth station is adjusted according to the difference between the level of a received reference signal, which is sent from a reference earth station to the satellite, and the level of its own received signal which is transmitted to the satellite from itself and is received at its own station after being relayed by the satellite. A transmission power of the reference earth station is adjusted so that the level of the received reference signal at the satellite is constant.
摘要:
A method for piling and cleaning a spun yarn in a wet spinning in which a yarn is withdrawn at a predetermined velocity and is dropped by its own weight into a rotating cylindrical container with the bottom formed with drain holes while simultaneously traversing the yarn in the radial direction of the cylindrical container so that the yarn is piled at the bottom of the cylindrical container in the form of a ring; and a cleaning liquid is sprayed against the yarn which is being piled, thereby cleaning the yarn.
摘要:
An electronic component includes an electronic component body. The electronic component body includes a base member including two opposed end surfaces, and two outer electrodes respectively disposed on at least the two opposed end surfaces of the base member. Two connection portions of two metal terminals are respectively connected to the two outer electrodes. A relationship of 6.4≦ h/t is satisfied where h is a length of each of two leg portions of the two metal terminals and t is a thickness of each of the two leg portions of the two metal terminals.

摘要:
There are provided a novel 3′-fluoro-5′-hydroxythalidomide derivative and an optically active substance thereof A 3′-fluoro-5′-hydroxythalidomide derivative represented by the general formula [A]: wherein R1, R2 and R3 are each a hydrogen atom; and X is C═O, and an optically active substance thereof. As analogs of thalidomide, the 3′-fluoro-5′-hydroxythalidomide derivatives are useful in the treatment of erythema nodosum of Hansen's disease, prurigo, rheumatism, Crohn's disease, graft-versus-host disease, Behcet's disease, myeloma, aphtha ulcer and the like. Further, the 3′-fluoro-5′-hydroxythalidomide derivative is useful as a drug used for treatment of multiple myeloma, TNF-α related diseases and the like.
摘要:
A method of transmitting adaptive modulation signals using space-time block code matrix from a plurality of antennas, the method comprising the steps of: changing adaptively the number of transmission repeat times of the matrix according to a propagation condition, transforming modulation signals at each transmission repeat timing from each antenna by using the matrix, and sending the transformed signals at each transmission repeat timing from each antenna.
