Title: Method of forming electrode of semiconductor device
Inventor: KOIKE KENICHI
IPC: H01L21/283
Filed: 1993-04-27
Abstract: PURPOSE:To reduce a part having a small distance between a gate electrode and a semiconductor substrate together with reducing the MIS capacitance by making an insulating layer to be formed overall on the semiconductor substrate into two layers of a high-density layer and a low-density layer. CONSTITUTION:An electrode pattern is formed on a semiconductor substrate by a photoresist, an insulating layer is formed overall the semiconductor substrate, a photoresist is removed so as to perform vapor deposition of a metal for an electrode on the surface of the exposed semiconductor substrate. Especially, the insulating layer on the semiconductor substrate is made into two layers of a high-density SiO2 layer and a low-density SiO2 layer. Then, the high-density layer is formed by a sputtering method having high bias voltage while the low density layer is formed by a sputtering method having a low bias electrode. In the insulating layer of high density, the photoresist and an end part of a removed part become steep so that the MIS capacity in an electrode part is not increased as in the case in the past.

Title: Binding method for coil end of underwater motor
Inventor: TAKEDA MASAHIRO
IPC: H02K3/50
Filed: 1982-07-15
Abstract: PURPOSE:To eliminate the production of a slack of the binding part of a coil end by binding the coil end with a binding material which has a strength of long lifetime. CONSTITUTION:The head part of a coil end 4 which is projected from a stator core 2 is bound by a binding material 5 to enhance the rigidity so as to prevent the coil end 4 and a lead 7 from fluctuating due to the turning flow or flow of water, liquid 9 produced due to the rotation of a rotor 8. In this case, the used binding material selects nonfibrous member. Since the nonfibrous binding material has longer lifetime than a fibrous binding material, the slack of the binding part of the coil end can hardly occur.

IPC: B23K9/09
Filed: 1981-08-10
Abstract: PURPOSE:To unify setting of welding conditions and select adequate conditions by providing a setter for welding current, a signal converter for welding voltage, a detector for welding voltage, control circuits for pulse and base voltages, and a converter and a control circuit for wire feed speed. CONSTITUTION:The material of base metals and the diameter of a wire are set with a switch 24, and an adequate current value is set with a setter 14 for welding current, thereafter a welding machine is started. Then the voltage signal Vi from the setter 14 is converted to a welding voltage signal Ve and a wire feed speed signal Vf. The signal Ve is distributed to a pulse voltage control signal  and a base voltage control signal, which are applied to respective regulators 7  and 8. Since the signal for the average value of the welding voltage of an electric power source 6 is fed back from a detector 16 for welding voltage, the  average value is controlled to a constant value determined by the set current.  The wire feed speed is also controlled to the constant value determined by the  set current value with a control circuit 21. When the set current value changes,  the three factors; pulse voltage, base voltage and wire feed speed, change as  well in follow up said change, whereby always adequate conditions are selected.

Abstract: PROBLEM TO BE SOLVED: To obtain culture soil for growing seedlings that is inexpensive and suitable for high-volume production and easy to handle without breakage and collapse and shows increased watering percentage because of its improved infiltration. SOLUTION: The objective culture soil 10 for growing seedlings comprises rice husks 12, sheath-core type conjugated fibers 14 and the fertilizers 16 for growing the seedlings, in addition, the soil is covered on its surface with nonwoven fabrics 18 and 19. Individual components (raw materials) are mixed by stirring and they are laminated so that the nonwoven fabrics 18 and 19 may be positioned on the surface layers. Then, the mixture is press-formed by heating them at the temperature at which the sheath of the sheath-core conjugated fibers 14 softens, but the core does not soften whereby individual components are wrapped and bound by the network of the sheath-core fiber 14.  Further, the nonwoven fabrics 18 and 19 entangle with the surface fine hairs of rice grain husks 12 thereby giving the objective soil 10 for culturing seedlings having excellent flexibility, water retention and infiltration. This soil 10 for culturing seedlings can be obtained from inexpensive raw materials and can be readily prepared by heat-forming simply in a large scale inexpensively. In addition, the soil is not broken or collapsed, even when it is watered and the small particles of rice husks 12 is not excluded from the surface of the soil.
