Title: Burst transferring error detecting method and microcomputer
Inventor: NISHIMURA AKIRA
IPC: G06F15/78
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To surely detect the generation of an error during burst transfer with simple configuration. SOLUTION: CPU 2 of a single chip microcomputer 1 gives a command to a bus adapter 7 in burst-transferring data between RAM 4 and an external I/O chip 11.

Title: Manufacture of thin film semiconductor element
Inventor: TAKEHARA NAOKO
IPC: H01L27/12
Filed: 1988-12-02
Abstract: PURPOSE:To prevent the scattering of VG-IDS characteristics among several transistors by making the roughness due to etching on an active layer surface smooth on the occasion of dry etching on a doping layer and stabilizing an interface between protetching and active layers. CONSTITUTION:After forming source and drain electrodes 16 and 17, a part of a doping layer 15 which is exposed between these electrodes is removed selectively by using the fore-going electrodes 16 and 17 as masks with a dry etching process where a fluorine-containing gas is used. After that, wet etching by the use of ammonium fluoride solution on the surface of an active layer 14 which becomes rough by etching makes the roughness on the surface of the active layer 14 smooth. Such a step stabilizes an interface between protecting and active layers 18 and 14 which are covered later on. When VG-IDS characteristics of respective transistors (for example 5 pieces) in a matrix array in which a plurality of this film transistors are formed are examined, it is obvious that they have superior characteristics which are free from scattering among several transistors.

Filed: 1990-11-09
Abstract: PURPOSE:To ensure that stable data recording is constantly performed by providing an electricity discharging device for discharging electricity from an ink ejection orifice surface at an opposite side to the ejection orifice surface of a recording device. CONSTITUTION:A blade 38 slides over a surface opposed to a medium for recording of a head holder 18 after passage over an ink ejection orifice surface. Then a brush for discharging electricity 41 is caused to slide over an area including the opposed surface, so that an electric charge generated on the front surface of the head holder 18 and the ink ejection orifice surface can be eliminated rapidly due to a sliding contact between the brush and the blade 38. Subsequently, the chances of foreign matter such as paper powder and materials afloat in the air sticking to the discharge orifice surface 14 or the front of the head holder are reduced significantly. In addition, the electricity discharging brush 41 of an electricity discharging device 40 is no longer contaminated by materials sticking to the ink ejection orifice surface 14 and the head holder 18 and thus electricity discharging effects are maintained significantly.
