Title: Thin-film transistor
Inventor: NAITO HIDEO
IPC: H01L29/40
Filed: 1990-11-22
Abstract: PURPOSE:To prevent the lowering of the breakdown strength of a gate insulating film due to hillocks by forming the electrode of a lower section in a gate electrode and source-drain electrodes in two-layer electrodes of a lower layer film composed of a rigid metal and an upper layer film consisting of titanium- contained aluminum. CONSTITUTION:The electrode 12 of a lower section in a gate electrode 12 and source-drain electrodes 16, 17 is formed in two layer electrodes of a lower layer film 12a made up of a rigid metal and an upper layer film 12b composed of Ti-contained Al. Consequently, the formation of an air gap between a gate insulating film 13 formed after the formation of the lower electrode 12 or a semiconductor layer 14 and the side face of the lower electrode 12 is prevented while the adhesive properties of the lower electrode 12 to a glass substrate 11, to which a thin-film transistor is shaped, are also improved, and no hillock is generated in the surface of the lower electrode 12 when the gate insulating film 13 formed after the lower electrode 12 is shaped is formed. Accordingly, the lowering of the breakdown strength of the gate insulating film due to the hillock can be obviated.

Title: Washing method for electroplating basis material
Inventor: SUGIYAMA SEIJI
IPC: C25D5/34
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To improve the production yield of an electroplating basis material by imparting the shearing force exceeding the max. pressure that its surface receives from pinch rolls to a basis material surface to wash the basis material surface thereby removing the dust, etc., press bonded to the basis material substrate by the pressure of the pinch rolls before introducing the basis material to an electroplating cell. SOLUTION: The occurrence of plating appearance defect is averted if the shearing force exceeding the max. pressure that the basis material surface receives from the pinch roll is applied on the basis material surface to wash the surface. The max. pressure is obtd. by measuring the pressing force of the pinch rolls to the basis material and determining the pressure that the basis material receives from a relation between this pressing force and a unit area. The shearing force of the spray washing water is calculated from the perpendicular force and injection angle of the spray. As a result, the deposits on the basis material surface are removed regardless of the number of press bonding of the pinch rolls. The basis material surface is washed with water or hot water of <=1.0g/l in the sludge content concn. in the washing water at need, by which the subsequent dust pickup is prevented.

IPC: H01L21/338
Filed: 1988-12-14
Abstract: PURPOSE:To manufacture a FET with a gate electrode displaced on a source region side as well as increased drain breakdown strength by a method wherein a gate electrode material films are selectively removed in obliquely downward direction from a drain region side using a double layer structured patterns as masks and then further removed in almost upright direction. CONSTITUTION:Gate electrode material films 41 are selectively removed by RIE process using a double layer structured pattern in almost T type symmetrical section as a mask. At this time, the RIE process is performed in two phases but when the process is performed in obliquely downward direction from a drain region 4 side of a semiconductor substrate 1, the gate electrode material films 41 remain on the undercut part in the source region 3 side of the double layer structured patterns due to the intensive directivity of the RIE process. Later, when the RIE process is performed in upright direction from the semiconductor substrate 1, the gate electrode material films 41 remain on the source region 3 side of the channel region. Next, photoresist films 12 and insulating films 21 are removed. Through these procedures, a FET with gate electrode material films 41 displaced to the source region 3 as well as increased drain breakdown strength can be manufactured.

Title: Method for preventing shaking in ladle refining
Inventor: KITAMURA SHINYA
IPC: C21C7/00
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To restrain the sloshing without extending time for uniform mixing even blowing a large quantity of gas by dipping a disk bottom surface in at least a part of bath surface. SOLUTION: The sloshing is the phenomenon, in which a bubble tower 4 turns in the circumferential direction with a blowing hole as an apex, thereby, the surface of the molten iron 2 is shaken in the vertical direction, and this is caused by the force acting to lift partially the bath surface when the blown bubbles are broken on the bath surface. Therefore, the lifting force is forcedly cancelled by dipping the disk 5 into at least a part of the bath surface to prevent even the sloshing. As the condition for the disk 5 to be possessed, the disk should have a radius of 0.05-0.15H to the gas blowing depth H and is dipped at the depth of $0.1H in a circle having the diameter of 0.2H while centering the vertical projecting point on the bath surface of the nozzle for gas stirring.

Title: Fuel injection control device for diesel engine
Inventor: KUWABARA ZENJI
IPC: F02D1/02
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To maintain proper fuel injection even when injection start time is changed by lowering the open valve pressure of a fuel injection nozzle. SOLUTION: A fuel injection control device calculates real injection start time T from a detected value by a nozzle lift sensor for each cylinder during idling of a diesel engine (S110) and calculates a deviation ΔT between proper injection start time T0 stored in ROM and the real injection start time T (S120). And timing correction values Δθ1, Δθ2, and Δθ3 are calculated from weighted average value ΔTa of deviation ΔT (S140). A map stored in ROM is used for calculation of the timing correction values Δθ1, Δθ2, and Δθ3. The calculated timing correction values #>=θ1, Δθ2, and Δθ3 are renewed and stored in backup RAM (s150). And the switching valve timing of an electro-magnetic spill valve is corrected for each cylinder using these timing correction values.
