A semi-contact guide apparatus includes a bed as a first member, a column as a second member, a plural number of oil-hold portions and an oil-supply device. The column is movably guided on the bed. A sliding surface is formed on the column. The plural number of oil-hold portions is formed on the sliding surface. Dimensions of the oil-hold portions are defined according to load distribution of the weight of the column. The oil-supply device supplies lubricant oil to the oil-hold portions. The amount of lubricant oil supplied to the oil-hold portion is defined according to each of dimensions of the oil-hold portions. Since the dimensions such as areas of the oil-hold portions and the amount of the lubricant oil supplied to the oil-hold portion are defined as above, inclination of the column on the bed is prevented, and the column can be smoothly moved on the bed.

A switching system which can easily reconnect a call to an original call path even if an original call state is disconnected at a time of transferring the call to another outside line or extension is presented. In a state where a call path between an outside line (or first line) and a call center (or second line) is formed, the outside line is connected to an outside line transfer destination (or third line) when a transfer demand from the call center to the outside transfer destination is received and the outside line is automatically reconnected to the call center when the call between the outside line and the outside line transfer destination ends.

A cavity resonator coupling type power distributor/power combiner can be used as a distributing amplifier or a combining unit. A first cavity resonator, having a single coupling terminal, and a second cavity resonator having a plurality of coupling terminals, are coupled by a coupling window or a coupling rod. As a result, a wide bandwidth of microwave electric power can be distributed or combined.

A DLC-coated member (100) has a base (200), an intermediate layer (300) that covers the surface of the base (200), and a DLC film (400) that covers the surface of the intermediate layer (300). The intermediate layer (300) has a five-layer structure, constituted of a first intermediate layer (301), a second intermediate layer (302), a third intermediate layer (303), a fourth intermediate layer (304), and a fifth intermediate layer (305). The five layers (301 to 305) are made of DLC to which Si has been added. Among the layers (301 to 305), the Si concentration in the first intermediate layer (301) is the highest, and that in the fifth intermediate layer (305) is the second highest. The Si concentrations in the second intermediate layer (302), third intermediate layer (303), and fourth intermediate layer (304) are lower than those in the first intermediate layer (301) and fifth intermediate layer (305).
摘要:
A method of producing a coated member in which a base material surface is at least partially coated with a diamond-like carbon film, the method includes: a diamond-like carbon film deposition process in which a diamond-like carbon film is formed on a surface of the base material by generating plasma by applying voltage to the base material in a processing chamber that stores the base material, while evacuating the processing chamber and introducing feedstock gas that contains at least a carbon compound into the processing chamber; and a hydrogenation process in which the deposited diamond-like carbon film is hydrogenated using hydrogen gas by stopping the voltage application and introducing hydrogen gas inducted instead of the feedstock gas, while the evacuation is being continued.

A bearing apparatus includes: two split outer ring halves which includes outer ring raceway surfaces and are disposed within a supporting hole of the housing, respectively; and a plurality of rollers which are disposed on respective inner surfaces of the both split outer ring halves and supports a shaft. Each of the two split outer ring halves includes an oil hole penetrating the split outer ring half in a radial direction thereof and an oil groove formed on an outer diameter surface of the split outer ring half along a circumferential direction thereof to allow the oiling passage and the oil holes to communicate with each other. Each of the oil holes is disposed at a position located at an angle of within 45° from the joint surface of the split outer ring halves in an opposite direction to a rotating direction of the shaft.

A radio communication system includes a first radio station for dividing codewords into communication units and transmitting the divided codewords by modulating them in every communication unit, and a second radio station for coupling and decoding signals obtained by demodulating the communication units. The radio stations have common information of first bits, equal to maximum bits per symbol of the communication units, and an encoding type list. The first station modulates and transmits the communication units with a modulation type with second bits. The second radio station receives the communication units modulated by the first radio station, demodulates the communication units with a modulation type with third bits, combines and decodes the demodulated signals with encoding types in the encoding type list, and obtains a result of the decoding, as reception information, by an encoding type in which no error is detected in the result of decoding.
摘要:
A metal part in which a base material of silicon-aluminum alloy having 1 to 25% by mass of silicon as an anode is immersed in an electrolyte together with a cathode, and at least a portion of a surface of the base material is anodized and coated with an anodic oxide film. A current density provided to both the anode and the cathode is increased from an initial current density of 0 A/dm2 at a rate between 0.15 and 0.35 A/dm2 per minute, wherein once the current density reaches a prescribed current density of between 0.8 A/dm2 and 1.2 A/dm2, the current density provided to the anode and the cathode is maintained at the prescribed current density.
