A C-type welding gun capable of accurately operating irrespective of the posture of the C-type welding gun without forcibly pressing electrodes to a workpiece and without considering thickness of the workpiece, wear of electrodes, etc. The C-type welding gun includes two servomotors attached to a housing, a C-shaped arm fixed to the housing and a movable arm provided in the housing. A mechanism for converting the rotation of the output shaft of one servomotor into the reciprocal motion of the movable arm is housed in the housing. A mechanism for converting the rotation of the output shaft of the other servomotor into the reciprocal motion of the C-shaped arm is provided between the wrist of the robot and the housing. Both the servomotors are simultaneously actuated while the other servomotor is stopped in response to the signal representing the contact of the electrode of the C-shaped arm to the workpiece.

A filter that filters carbon dioxide in the gaseous, liquid or supercritical state is efficiently purified. The carbon dioxide is used to at least clean or dry an object to be treated, or to clean or dry the object to be treated. A method of purifying a filter for filtering carbon dioxide in a gaseous, liquid or supercritical state is provided. The carbon dioxide is used to at least clean or dry the object to be treated, or to clean and dry the object to be treated. According to the method, the filter 13 is purified before the carbon dioxide is filtered in the gaseous, liquid or supercritical state by the filter 13. The filter 13 is purified by allowing carbon dioxide to pass through the filter.

A high-quality mass spectrum is provided with alleviated mass/charge axis deviation in a triple quadrupole mass spectrometer even when executing a high-speed mass scan with MS/MS analysis. Mass calibration tables which denote relations between m/z and a mass deviation value which scan speed is a parameter are prepared separately for use in MS analyses without involving dissociation operations and MS/MS analyses with involving dissociation operations. According to a measuring mode, such as a product ion scan measurement or a neutral loss scan measurement, when performing MS/MS analysis, a mass deviation value for the minimum scan speed in a table is used for a quadrupole where the selected m/z is fixed, and a mass deviation value for a designated scan speed in a table is used for a quadrupole where the mass scan is performed, thus controlling the operations of each of a pre-stage and a post-stage quadrupoles.

As a control parameter given to a direct-current (DC) voltage generator which generates a DC voltage for ion selection, a “mass-related offset” for allowing an adjustment of the offset for each mass-to-charge ratio is provided in addition to the “gain” and “common offset” which respectively determine the gradient and position of a scan line drawn on a stability diagram during a mass-scan operation. In an automatic adjustment operation using a standard sample, under the control of an automatic regulator, the “gain” and “common offset” are initially set, after which the “mass-related offset” for each mass-to-charge ratio is determined so that the mass-resolving power will be substantially uniform, and these data are stored in a control data memory. In an analysis of a sample of interest, a quadrupole voltage controller controls the DC voltage generator and a radio-frequency (RF) voltage generator according to the control parameters read from the memory.

In a nonvolatile semiconductor memory device, a memory cell array has a plurality of nonvolatile memory cells arranged in a matrix. A selecting section selects as selection memory cells, at least two of the plurality of nonvolatile memory cells from the memory cell array. A write section applies to the selection memory cells, a gate voltage which increases step by step, until a threshold voltage of each of the selection memory cells reaches a target threshold voltage, such that the threshold voltage increases step-by-step.

A semiconductor memory device includes: a memory array; an internal address supplying unit configured to produce a first internal address in response to an external address; a first fuse unit configured to includes fuses and anti-fuses integrated; an address switching circuit configured to produce a second internal address on the basis of the first internal address; and a decoder circuit configured to select a memory cell of the memory array in response to the second internal address. The internal address supplying unit is configured to be capable of fixing a specific address bit in the first internal address. The second internal address includes: fuse independent address bits produced from address bits which is not the specific address bit in the first internal address, independently of a state of the first fuse unit, and a fuse dependent address bit having a value corresponding to the state of the first fuse unit and a vale of the specific address bit.
