A position detection apparatus of the electrostatic coupling type is provided, to detect not only a position of a pointer but also information other than the position information such as, for example, pointer pressure or side switch information. The pointer transmits two codes such that a pressure applied to a pen tip is associated with a time difference between the two codes. A position detector carries out a correlation matching operation between signals generated in reception conductors and correlation calculation codes corresponding to the two codes, to thereby detect a position on a sensor section pointed to by the pointer from a result of the correlation matching operation and based on at least one of the codes. The position detector further includes a pressure calculation circuit for detecting pressure applied to the pointer, which is associated with the time difference between the two codes, from the result of the correlation matching operation calculated by the correlation matching operation and based on the two codes.

A digital image signal is transformed in frequency, thereby providing partitioned frequency components. Characteristic information is calculated in accordance with a coefficient at a first frequency domain that is selected from among the partitioned frequency components. A coefficient at a second frequency domain is handled in accordance with predetermined rules, thereby embedding the characteristic information into the coefficient at the second frequency domain. The second frequency domain is selected from among areas that differ from the first frequency domain. The frequency coefficients that exhibit several frequency components are encoded in a predetermined manner, thereby producing compressed image data.

It is arranged so that ions can be analyzed accurately and with high sensitivity. A first electrode 11 is provided on the outer periphery of a dielectric cylindrical body 13 and a second electrode 12 is placed inside the cylindrical body 13 leaving a clearance between itself and the inner surface of the cylindrical body 13. When an AC high voltage is impressed across the first electrode 11 and second electrode 12, a barrier discharge occurs within the cylindrical body 13. When a distal end portion 12a of the second electrode 12 projects outwardly from the distal end of the cylindrical body 13, a thermal equilibrium plasma P having a low electron temperature is generated outwardly of the distal end of the cylindrical body 13 without a plasma jet ascribable to the barrier discharge emerging outwardly from the distal end of the cylindrical body 13. By exposing a sample S to the thermal equilibrium plasma P, particles (atoms, molecules) desorbed from the sample S undergo soft ionization without being decomposed or polymerized. The ions generated are introduced to a mass analyzer 50.

The ink cartridge has a first detection target portion for detecting ink level and a second detection target portion for identifying the type of an ink cartridge.
