The portable electronic apparatus has a box-like casing having a peripheral wall, and a pack receptacle defined within the casing. The pack receptacle has an opening portion opened in the peripheral wall. A packaged functional component is stored in the pack receptacle, such that the functional component can be detached therefrom through the opening portion. The pack receptacle of the casing is provided with a locking member for holding the functional component. The locking member is movable by manual operation between a locked position where the locking member is hooked on the functional component and a lock-released position where the locking member leaves the functional component. The pack receptacle is provided with a spring for energizing the functional component in the direction in which the functional component is pushed out through the opening portion. The opening portion of the casing and the locking member are covered with a detachable cover.

An element isolation film is formed by filling an oxide in a trench formed in an element isolation region of a semiconductor substrate to thereby form an insulation film for element isolation. A method of forming the element isolation film includes a first step of depositing a material in a plasma state including oxygen and silicon on an inner surface of the trench while applying no bias voltage (or a relatively low voltage), and a second step of filling the material in a plasma state including oxygen and silicon in the trench while applying a bias voltage (or a relatively high voltage).

To provide an arc start method in a consumable electrode type arc welding method capable of firmly executing arc start and capable of executing high quality high speed welding by restraining a welding defect from being brought about therefor, at a portion of a wire projected from a welding tip, a temperature of a front end portion of the wire is made to be at a temperature higher than a temperature of a portion thereof near the welding tip. The front end portion of the wire is preheated to 300° C. or higher, preferably, 450° C. or higher. The front end portion of the wire is preheated by generating arc for preheating. The preheating arc is generated in a spot-like shape at a position near a terminal end portion of a predetermined welding line by constituting a current lower than a welding current.

A high-temperature lubricating oil composition is provided, which is resistant to hardening and sludge formation, and displays minimal evaporation loss and superior thermal stability, even under practical high-temperature open system conditions such as those found in a tenter. A lubricating oil composition that provides excellent lubrication without damaging members used within working machinery is also provided. The lubricating oil composition comprises a polyolester based synthetic oil and a C12 to C72 fatty acid and/or a diphenylamine derivative containing an arylalkyl group with a number average molecular weight of 400 to 800.

There is provided a radiation tomographic imaging apparatus and a radiation tomographic imaging method which allows the ECG information and the X-ray tube current value to be monitored while obtaining required projection data for the image reconstruction. The radiation tomographic imaging method for forming a tomographic image of a subject by means of the radiation from the radiation source comprises the ECG wave output step for measuring the heartbeat of the heart of the subject to output as the ECG wave signal; a variable output step for varying the radiation output based on the ECG wave signal; a determining step for determining the tomographic image reconstructed based on the projection data obtained by the radiation output having been varied is good or no good; and a displaying step for displaying the ECG wave signal, the radiation output, and the reconstruction data area for forming a tomographic image if the image is no good.

A radiation tomography system includes a radiation source and a radiation detector opposed to the radiation source with a subject between them. The radiation tomography system further includes a scanner that scans a subject by moving the radiation source and radiation detector while rotating them about the subject; a calculator that calculates a control value with which an exposure of a radiation emanating from the radiation source is controlled; and a display on which at least one of calculated control values associated with positions in the direction of rotation of the scanner and control values associated with positions in the direction of a body axis linking the subject's head and the subject's tiptoe is displayed in relation to the respective pieces of positional information on the subject.

A printed circuit board, a heat radiating shield plate formed of a metallic plate, a printed circuit board and a shield plate are arranged in a base section of a apparatus body in a stacked state. Studs made of a metal projects from the heat radiating shield plate. Both ends of each of the studs come in contact with ground areas of the printed circuit boards and are electrically connected to these ground areas. A CPU mounted on one of the printed circuit boards comes in contact with the heat radiating shield plate through a cool sheet and is thermally connected to the heat radiating shield plate.
