Title: MULTIPORT AMPLIFIER PROVIDED WITH AMPLIFIER ELEMENTS OF NUMBERS EXCEPT N-th POWER OF 2
Inventor: NOBERON ROZARIO
IPC: H03F3/68
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a parallel amplifier obtained by parallelly arranging amplifiers of numbers other than 2N in which N for performing interconnection by a hybrid and making channels, i.e., performing channelization is an integer. SOLUTION: A plurality of amplifiers of numbers which are other than 2N of a fixed array and N is an integer are parallelly arranged by utilizing the hybrid of a fixed array obtained by combining the input ports and output ports of the amplifiers. An input signal applied to any of the parallelly combined input ports is made to parallel so as to pass through a parallel amplifier of the same number as that through which a signal applied to any port other than the input port passes. In a particular example, ten and twelve parallel amplifiers are used, and a signal applied to an optional input port is divided so as to be caused to pass through eight amplifiers among the ten or twelve amplifiers. Thus, redundancy and EIRP(effective isotropically radiated power) flexibility are improved.

Title: Method for producing acetic anhydride
Inventor: YAMASHITA MITSURU
IPC: C07C51/573
Filed: 2001-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for economically and stably producing high- quality acetic anhydride. SOLUTION: This method for producing purified acetic anhydride by distilling crude acetic anhydride in a distillation column 7 involves recycling the low- boiling fraction distilled off the distillation column 7 after ozone treatment thereof in an ozone treatment column 8. Since the acetic anhydride in the low- boiling fraction is recycled without being returned to a crude acetic anhydride production plant 1, returning of the acetic anhydride into ketene again or the like is suppressed, resulting in improving economy through suppressing acetic anhydride yield drop and/or energy loss. Further, unsaturated compounds contaminated in the low-boiling fraction are oxidized and gone by the above ozone treatment, and the concentrations of the unsaturated compounds affecting the hue of the final acetic anhydride is also prevented from rising in the distillation column 7, therefore the objective high-quality, purified acetic anhydride can be produced stably.

Title: Power source circuit
Inventor: SHIMODA SADAYUKI
IPC: H04N5/63
Filed: 2001-03-26
Abstract: PROBLEM TO BE SOLVED: To overcome the problem such that power supply to an infrared radiation receiving circuit and a microcomputer must be continued in order to receive a remote control signal when image receiving is turned off in a domestic electrified apparatus like a television receiver, which is called as standby time consumption power, and electric power of about 1W is consumed only in an AC-DC converter whose efficiency is low. SOLUTION: The AC-DC converter is not always operated, but electricity is stored in a charge storing means and power is supplied to the microcomputer and the infrared radiation receiving circuit. Before a voltage of the storing means becomes lower than or equal to a prescribed value, practically, the lowest operation voltage of the microcomputer and the infrared radiation receiving circuit, the charge storing means is charged by operating the AC-DC converter. The charging is stopped before the voltage becomes higher than or equal to a prescribed voltage, practically, the highest operation voltage of the microcomputer and the infrared radiation receiving circuit. Thereby the operation frequency of AC-DC converter is reduced and the power in the AC-DC converter whose power efficiency is the worst is reduced, so that the whole standby time consumption power can be reduced.

Title: Control of tongue and groove joint load and air/oil seal temperature of turbine
Inventor: SCHMIDT MARK CHRISTOPHER
IPC: F01D11/00
Filed: 2001-04-06
Abstract: PROBLEM TO BE SOLVED: To control a mass flow rate of an exhaust fan to maintain a tongue and groove joint load while preventing a fire of a bearing from occurring due to high temperature of an air/oil seal. SOLUTION: Since a tongue and groove joint on which a load between the forth stage wheel and the rear shaft of a machine is exerted is brought into a non-load state, when a bearing blower is turned on, a gap is provided by thermal mismatching of the tongue and groove joint. When the tongue and groove joint is opened or brought into a no-load state, each part is relatively moved and thereby, the rotor loses a balance. When the bearing blower is turned off during operation, the temperature of a front air/oil seal will exceed a maximum design execution reference by soak back. When the temperature of the air/oil seal exceeds a set maximum design limit, as a result, a bearing is caused to effect firing and an extremely serious impact is exerted on a machine.  By controlling the bearing blower according to an optimized blower profile, the tongue and groove joint load can be maintained and the temperature of the air and oil seal can be maintained at a set limit or less. The blower profile is decided according to the thermodynamics model of a system.
