Title: Word processor and cursor shift unit changing system
IPC: G06F3/0481
Filed: 1992-03-23
Abstract: PURPOSE:To provide a word processor and a cursor shift unit changing system which can quickly change the shift unit of a character cursor which moves in the shift unit in accordance with the cursor size into the least value with a simple operation. CONSTITUTION:When a cursor shift key is pushed on a keyboard 6, a cursor shift controller 2 calculates the next shift position of a character cursor by a position calculation device 4 based on the reference coordinates stored in a reference coordinate storage buffer 3 and the relevant shift unit.

IPC: B21C37/09
Filed: 1979-05-28
Abstract: PURPOSE:To prevent seizure accident or the like by applying a copper plating film on one surface of a steel sheet and chemical conversion film on the other surface. CONSTITUTION:A copper plating film 2 (for example 2-5mu) is formed on one surface of a steel sheet 1 (for example, 0.3-1.0mm.) and a chemical conversion film 3 (for example 2-8mu) composed of phosphate, iron oxalate or tri-iron tetroxide is formed on the other surface. Parallel tapered faces 11, 12 are worked at edge parts on both broadside ends and with the copper plating film 2 side being made outside circumferential face, the sheet is pressure-joined in double winding in the width direction. Parallel with this pressure-joining, the parallel tapered faces 11, 12 of both edge parts are butted by central offset part 4. This is heated in an atmosphere controlled furnace to braze the mutual overlapped circumferential surfaces and at the same time, the chemical conversion film 3 of the inside circumferential face 5 is erased by the heating. Thereby, the seizure on the inside circumferential surface owing to the friction heat during work is prevented and the problems owing to chemical reaction with internal fluid in use as piping etc. are solved.

Title: Thin film transistor
Inventor: MISHIMA YASUYOSHI
IPC: H01L29/78
Filed: 1989-03-16
Abstract: PURPOSE:To improve a thin film transistor of this design in reliability and characteristics by a method wherein a silicon nitride film, whose interface part with an operating semiconductor layer is larger than the other interface part with a gate electrode in energy band gap, is used as a gate insulating film. CONSTITUTION:A gate insulating film 3 of an SiN film is formed through a reactive sputtering method in which a reactive atmosphere composed of NH3 and SiH4 is kept constant in composition. The interface part 31 of the film 3 with a gate electrode and the other interface part 32 with an operating semiconductor layer are formed through RF powers of 50W and 400W respectively. Under a condition that an RF power is kept low, SiN contains more interface states, so that charges are hardly injected into the film 3 and consequently it becomes insensitive to a voltage stress. On the other hand, the characteristic of a TFT is dependent on the film property of the interface part of the SiN film 3 with the a-Si layer 4. As the film 32 is formed through a high RF power that a film low in density of interface level is obtained, the TFT of this design is excellent in characteristics. As mentioned above, a gate insulating film is formed by combining two types of films, whereby a thin film transistor of this design can be insensitive to a voltage stress retaining excellent characteristics.
