Abstract: A boom foot pin is attached to a pair of vertical plates so as to be able to be pulled out along an axial direction of the boom foot pin. A housing box has a box main body with a housing space inside and an opening/closing lid configured to allow an opening region of the box main body to be opened and closed. The box main body is disposed on the right of the right vertical plate in a state where the boom foot pin is placed opposite the housing space with reference to the opening region in a side view in which the upper slewing body is viewed along an axial direction and the box main body is shaped to open the boom foot pin in the axial direction. The opening/closing lid is rotated to a position where the opening region is closed to lie at a position where the opening/closing lid overlaps the boom foot pin in the side view, and is rotated to a position where the opening region is opened to lie at a position where the boom foot pin is opened in the axial direction.

Abstract: [Problem] Provided is a novel 1,3,4,8-tetrahydro-2H-pyrido[1,2-a]pyrazine derivative or a pharmaceutically acceptable salt thereof, or a solvate thereof, which is useful as an anti-HIV agent. [Solving Means] The present invention provides a compound represented by the following formula [I] wherein each symbol is as defined in the specification, or a pharmaceutically acceptable salt thereof, or a solvate thereof.

Abstract: The present invention relates to a nitrogen-containing fused ring compound represented by the following formula [I] wherein each symbol is as defined in the specification, or a pharmaceutically acceptable salt thereof, and an anti-HIV agent containing such compound. The compound of the present invention has an HIV integrase inhibitory activity, and is useful as an agent for the prophylaxis or treatment of AIDS, or as an anti-HIV agent. In addition, by the combined use with other anti-HIV agents such as a protease inhibitor, a reverse transcriptase inhibitor and the like, it can be a more effective anti-HIV agent. Because it shows integrase-specific high inhibitory activity, the compound can be a pharmaceutical agent safe on human body, which causes only a fewer side effects.

Abstract: An images combination processing system has a CCD or an imaging element including CCDs for picking up an image, compression processing portions for applying JPEG compression, etc. to image data in respective areas into which a picked-up image is divided, a buffer for storing temporarily compressed data that were processed by the compression processing portions, a compressed data combining portion for reading the compressed data being processed by respective compression processing portions from the buffer and combining them into one image file, and a storage media. Each compression processing portion has a restart marker inserting portion for inserting restart markers into the compressed data while circulating eight types of restart markers and also inserting a special restart marker into a rearmost portion of the compressed data, and a data length counter for counting a data length of the compressed data to which the restart markers are inserted.

Abstract: In an imaging section, an image of an object is converted to signal charge by photodiodes arranged in the form of a matrix, the signal charge is transferred to output circuits by vertical transfer paths, and then the signal charge transferred to the output circuits is converted to signal voltage by the output circuits. The signal voltage is output from the output circuits to a signal conversion section as signals. The signal conversion section performs a processing for the signals in parallel, and outputs the processed signals to a display section. In the display section, signals are converted to voltage by input circuits, and the voltage is respectively applied to drain buses. A vertical driving circuit scans gate buses, and supplies gate driving pulses. Field effect transistors supplied with the gate driving pulses store charge in response to the voltage applied to liquid crystal devices, thus displaying an image.

Abstract: Bus-connected circuits are made to operate stably and at high speed. A cache memory for high-speed access and a DRAM for low-speed access are connected to a CPU by an address bus, control bus and data transfer bus. A switch is provided in the bus at a point between the cache memory and DRAM and the switch is opened at the time of high-speed access. Since bus length is essentially shortened at such time, the cache memory can be accessed stably at high speed. When the DRAM is accessed, the switch is closed.

Abstract: This invention provides a laser welding method capable of supplying a filler wire to a welding object portion in a stabilized condition so as to stabilize welding quality. More specifically, the filler wire is supplied to the welding object portion while the laser beam is projected to the welding object portion. At this time, the filler wire is supplied obliquely from forward or backward in the welding advance direction such that the angle between the supplying direction and beam axis L of the laser beam is less than 45°.

Abstract: Consumption of power in a digital electronic still-video camera is reduced. Specifically, a digital electronic still-video camera includes a first memory module circuit and a second memory module circuit controlled by a memory module circuit so as to be placed in active and standby states. When one memory module circuit is in the active state, the other memory module circuit is placed in the standby state, thereby making it possible to reduce power consumption.
