IPC: B41J2/175
Filed: 1999-12-28
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder in which an appropriate quantity of ink is supplied to a main ink tank for supplying ink to a recording head. SOLUTION: A main tank 20 disposed on a moving carriage has a first ink chamber 32 holding ink under free state along with air.

IPC: H01L21/22
Filed: 1990-12-27
Abstract: PURPOSE:To reduce defects such as dislocation existing in a compound semiconductor produced on a semiconductor substrate by epitaxial growth. CONSTITUTION:When the temperature of a semiconductor wafer obtained by subjecting a compound semiconductor to epitaxial growth on a semiconductor substrate is lowered from a temperature capable of carrying out rearrangement of crystal of the compound semiconductor (time: t8 to t9), only boundary part between the compound semiconductor and the semiconductor substrate is locally heated by irradiating the semiconductor wafer with laser beam.

As a result, the crystal of the compound semiconductor is fixed and it is prevented that a crystal defect produced in the boundary part affects on the compound semiconductor.
