摘要:
A high-performance SAW filter is to be provided which has lower insertion loss in a pass band and high attenuation in an attenuation band on the low frequency side of the pass band. In a SAW filter with attenuation poles configured of a two-port circuit for filtering for forming a ladder type SAW filter using a SAW resonator and a two-port circuit for impedance formed of an impedance serially connected, the impedance of the two-port circuit for impedance is configured so as to form an attenuation band of a predetermined width having a sufficient attenuation characteristic on the low frequency side of a pass band.
摘要:
A single crystal production method based on the Czochralski method comprises controlling a number of crucible rotations and crystal rotations so that a number of vibrations for driving a melt, determined on the basis of the number of crucible and crystal rotations during a single crystal growing procedure, is outside a range from 95% to 105% of a number of sloshing resonance vibrations of the melt. In another embodiment, the method comprises controlling a number of rotations of a crystal and crucible, so that when a number of vibrations for driving a melt, determined by the number of crucible and crystal rotations during a single crystal growing procedure, is within a range from 95% to 105% of a number of sloshing resonance vibrations of the melt, the number of vibrations of the melt due to sloshing does not exceed 2000 times during a period when the number of vibrations is within that range.
摘要:
A surface acoustic wave filter includes an antenna terminal, an antenna, a transmitting filter, a branching line and a receiving filter. The antenna is coupled to the antenna terminal. The transmitting filter is coupled to the antenna terminal. The transmitting filter receives an electrical power. The branching line is coupled to the antenna terminal. The branching line has a first length that is longer than λ/4 length so that the electrical power received by the transmitting filter when the antenna terminal is opened is smaller than when the antenna terminal is terminated, wherein λ is a wave length of a center frequency of transmitted and received bands of the surface acoustic wave filter. The receiving filter is coupled to the branching line.

The invention has for its object to provide a titanium oxide-containing paper possessed of satisfactory deodorizing power and well protected against aging of paper, a corrugated board fabricated from the titanium oxide-containing paper, and a deodorizing element constructed using the corrugated board. The titanium oxide-containing paper comprises an ultrafine particulate titanium oxide with an X-ray particle diameter of not larger than 100 nm (T) or a modified ultrafine particulate titanium oxide available on surface-modification of (T) with a metal or a metal compound (T'), at least one inorganic filler (F) selected from the group consisting of sepiolite, silica gel, bentonite, zeolite, magnesium sulfate, asbestos, and active carbon for supporting the titanium oxide (T) or (T'), and an organic fiber material amenable to web formation by papermaking machine. The deodorizing element is constructed by stacking up a multiplicity of units of the above-mentioned corrugated board.
摘要:
A method for controlling an early stage casting in a continuous casting process comprising the steps of commencing to pour molten steel into a mold provided with a dummy bar head through an immersion nozzle provided with a flow rate control device, detecting that a steel level in the mold has reached a predetermined drawing commencement level and commencing drawing of the dummy bar head. A holding time for molten steel in the mold is predetermined, from the commencement of pouring molten steel into the mold to a commencement of the drawing of the dummy bar head, through a solidified shell formation velocity under prevailing operating conditions, and a prediction is made of whether or not, when the steel level has reached the predetermined level, a molten metal holding time substantially equal to the predetermined molten metal holding time can be obtained, and the flow rate of the molten steel is controlled in accordance with the result of the prediction.
