摘要:
A bit apparatus in which a cutter member having cutting teeth is axially supported on a shaft for rotation about the shaft, and a bearing mechanism is interposed between the cutter member and the shaft. The bearing mechanism includes at least a radial bearing for bearing a radially directed load and a thrust bearing for bearing an axially directed load. The radial bearing has a shaft-side split bearing member and a cutter-side split bearing member that are opposed to or in sliding contact with each other and capable of rotating relative to each other.

A system and method for unthrottled intake air control for an internal combustion engine. The engine has at least one combustion chamber provided with electromagnetic intake means. The opening and closing times of the intake means are adjustable entirely independently from the crankshaft position to control intake air supplied to the combustion chamber. A control unit is used to implement instructions for determining a first portion of requested intake airflow, which first portion requests a first engine response performance, and instructions for determining a second portion of requested intake airflow, which second portion requests a second engine response performance. The control unit implements instructions for processing the first and second airflow portions to make contributions to the first and second engine response performances, respectively, instructions for determining an intake means activation command, and instructions for providing the intake means activation command to the intake means to provide an engine response performance combining the first engine response performance with the second engine response performance.

A radio control device includes a transmitter, in which a crystal type high frequency module equipped with a high frequency circuit corresponding to a frequency band of a carrier and a PLL high frequency module equipped with the high frequency circuit and a PLL circuit for controlling a frequency of the carrier depending on a phase difference between the carrier and a reference signal of oscillator are detachably mounted. Such construction permits the crystal type high frequency module and PLL high frequency module to be selectively used as desired and transmission data to be output by means of the carrier of a desired frequency set depending on the high frequency module. Also, the radio control device includes a receiver which employs a frequency synthesizer system in which a PLL circuit for controlling an oscillation frequency depending on a phase difference between a reference signal and the oscillation frequency is used and includes a frequency selecting means for selecting a required frequency from a plurality of predetermined frequency data and a frequency setting means for fixedly setting a receive frequency on the frequency selected by the frequency selecting means when a power supply is turned on.

A data transfer device that confirms completion of writing into a memory on transferring data to the memory via a bus through which a response indicating completion of data writing in the memory is not sent back includes an inter-memory data transfer control unit performing data transfer between the memories. When the inter-memory data transfer control unit detects switching of a write destination memory from a first memory to a second memory, in order to confirm that writing into the first memory is completed, the inter-memory data transfer control unit performs confirmation of write completion as to the first memory by a procedure different from writing into the memory. When a data transfer with a designated transfer length is completed, in order to confirm that writing is completed as to the write destination memory at the end of the data transfer, the inter-memory data transfer control unit performs confirmation of write completion as to the write destination memory at the end of the transfer by the procedure different from writing into the memory. The inter-memory data transfer control unit notifies the processor of completion of an inter-memory data transfer based on the confirmation of write completion.

A transparent plastic container which is transparent, allows good design and can be used for an anticounterfeit system that determines authenticity by visual check with the use of polarization property. A transparent plastic sheet of a polystyrene-based resin having a total light transmission of 85% or higher and a haze of 7% or less is subjected to vacuum, pneumatic or vacuum/pneumatic forming at a sheet temperature ranging from a glass transition temperature plus 50 degrees C. to a glass transition temperature plus 130 degrees C., thereby obtaining a transparent plastic container having a planar portion with a strain amount of 150 nm or less.

The present invention provides means for effectively reducing the amount of data by means of de-duplication in a disk array apparatus having a data guarantee code. A control means for the disk array apparatus that adds a data guarantee code to each logical data block and checks the data guarantee code when reading data has a de-duplication performing function and control means for: generating LA substitution information for a function checking the data guarantee code or read data location address substitution information when performing the de-duplication and storing data; performing the de-duplication using the above-mentioned information when reading data; and thereby avoiding false diagnosis of the data guarantee code check.
摘要:
The object of the invention is to prevent a large amount of unnecessary images from being displayed on an image on a liquid crystal display panel, due to a signal value of a pulse width modulation signal (PWM) which exceeds the minimum signal value of a vertical synchronization signal when the vertical synchronization signal (VS) interferes with the pulse width modulation signal (PWM) within a period of one frame. A liquid crystal display panel controller makes an intermediate signal value (M1) of the vertical synchronization signal (VS) higher than the maximum signal value (H2) of the pulse width modulation signal (PWM) within at least a part of the period of one frame for the vertical synchronization signal.

A semiconductor light-emitting device includes a support structure, and a light-emitting structure. The support structure includes a support substrate, and a support substrate side bonding layer disposed on one surface of the support substrate. The light-emitting structure includes a light-emitting structure side bonding layer bonded to the support substrate side bonding layer, a reflection region disposed on the support substrate side bonding layer opposite the support substrate, and a semiconductor multilayer structure including a light-emitting layer disposed on the reflection region opposite the light-emitting structure side bonding layer for emitting a light with a predetermined wavelength, and a light-extraction surface disposed on the light-emitting layer opposite the reflection region for reflecting diffusely the light. The reflection region includes a transparent layer of a material with a lower refractive index than that of the semiconductor multilayer structure, and a reflection layer of a metallic material. The transparent layer has such a thickness that interference caused by multiple reflection of light inputted to the transparent layer can be suppressed.
