Title: Coating method for cream solder on printed circuit board
Inventor: ISHII TAKAAKI
IPC: H05K3/34
Filed: 1990-11-16
Abstract: PURPOSE:To reduce the quantity of cream solder to be coated on a printed circuit board by providing a resist layer except a predetermined part of a metal pattern on a base material, extending the solder on the resist layer by a squeegee, and coating the predetermined part of the pattern with the solder. CONSTITUTION:A printed circuit board 21 is coated with cream solder 28 by extending the solder 28 placed on a resist layer 26 by a squeegee 30. Thus, the solder 28 flows to the predetermined part of a metal pattern 22 in which the layer 26 is not provided. In this case, the thickness of the solder 28 to be fed to the predetermined part of the pattern 22 is the same as that of the layer 26. Thus, the quantity of the solder 28 to be coated on the board 21 is remarkably reduced as compared with a conventional method using a metal mask.

Title: Ptc heater control device, controller and current limiter used for the device
Inventor: MASUDA TAKAFUMI
IPC: H05B3/14
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a PTC heater controller device capable of raising a breaker utilization factor nearly to a rating and having cost lowered via the reduction of the number of breakers and the number of controllers connected thereto, as well as a controller and a current limiter used for the control device. SOLUTION: Regarding a PTC heater control device for turning on and off alternate current supplied from a commercial power supply to PTC heaters 1 to 4 having a PTC ink layer as a heating body, a ratio for limiting AC current is divided into a plurality of stages and gradually lowered within a preset time after turning on the power supply and a current limiting operation without any current limitation at a final stage is made. This PTC heater control device is characteristic in that current limitation at each stage which is made with only a part of an AC cycle intermittently turned on. According to this construction, rush current when turning on the power supply is limited and a large breaker for rated current is not needed for the rush current, thereby improving a breaker utilization factor.

Filed: 1986-12-30
Abstract: PURPOSE:To miniaturize an outside fan, by a method wherein a bearing is cooled by one part of cooling air, introduced from an air inlet port through the outside fan equipped with vanes for cooling the main body of the title machine. CONSTITUTION:Cooling air, introduced from an air inlet port 5 by an outside fan 1A provided with vanes 1a for cooling the main body of the title machine, passes through a ventilating passageway 9 for cooling the main body and a first connecting tube 13 and is sent into the ventilating passageway 12 for cooling a bearing. The cooling air, passed through the ventilating passageway 9, passes through a main body cooler 3 and cools air inside of the rotary machine main body 4, thereafter, is discharged to the outside of the machine. On the other hand, the cooling air, sent into the passageway 12, absorbs heat from the surface of a bearing box 7 and cooling fins 10, attached to the surface of the box 7, passes through a second connecting tube 14 and is joined with the air, which passed through the ventilating passageway 9, thereafter, flows into the main body cooler 3 to cool the inside air of the rotary machine main body 4. Accordingly, the provision of exclusive vanes for cooling the bearing is not necessitated for the outside fan 1A, therefore, the outside fan 1A may be miniaturized.

Title: Manufacture of printing plate
Inventor: YOSHIDA ICHIRO
IPC: B41C1/10
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To obtain a clear printing plate having no fog without adhering offset ink to the hydrophilic part of a non-image part by spraying ink mixed with ethylene tetrafluoride resin part by spraying in moisture in an aqueous soluble synthetic resin solution, thereby forming a film having water repellency. SOLUTION: An ink obtained by mixing an ethylene tetrafluoride resin powder dispersible in moisture with an aqueous soluble synthetic resin solution is sprayed onto a hydrophilized recording material to form a film having water repellency thereby to form an image, thereby forming a printing plate. That is, this is a method for forming the plate having the step of forming the image by using functional ink by a direct ink jet type on the surface treated recording material. This method has less forming steps of the plate, and makes it possible to treat in a short time. Thus, the ink is injected by an ink jet printer to form the image on a board, thereby making it possible to form a highly precise printing plate.

Title: Shadow mask forming pattern and manufacture thereof
Inventor: HIDESHIMA TAKAFUMI
IPC: G03F1/00
Filed: 1988-12-09
Abstract: PURPOSE:To eliminate electron beam omission and cope with a high-precision large shadow mask by providing an expanded section made larger toward the outer periphery from the mask center on the periphery on a back pattern corresponding to the holed face of a shadow mask. CONSTITUTION:A main pattern A is exposed by slot exposure, then an auxiliary pattern B having a diagonal axis across the center point S2 of the length 11 of the main pattern and the point S3 is exposed to form an expanded section. An auxiliary pattern C is exposed and developed between S1 and S2 of the main pattern A to obtain a back pattern 1. A back pattern 2 is obtained by omitting the expanded section of the pattern C. The size of the expanded section is selected as appropriate, e.g., it is made larger in sequence outward from the center. When auxiliary patterns smaller than the main pattern are combined and duplicatively exposed, electron beam omission is eliminated, and a high- precision large shadow mask can be coped with.

IPC: C11C3/10
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To realize purification in high yield and high purity, by subjecting a fatty acid ester formed from a lower alcohol and a long-chain fatty acid containing an ω-3 highly unsaturated fatty acid to preferential alcoholysis with a linear higher alcohol by using a lipase. SOLUTION: A long-chain unsaturated fatty acid having at least 4 to 6 double bonds, comprising, e.g. bonito oil is subjected to esterification in a 1-4C lower alcohol such as ethanol in the presence of a catalyst comprising, e.g. sodium ethylene to produce a fatty acid ester comprising, e.g. ethyl ester of bonito oil, which is concentrated by, e.g. molecular distillation to give a highly unsaturated fatty acid ester. This ester is mixed with an 8-18C long-chain higher alcohol, such as lauryl alcohol, at a molar ratio of (1:2) to (1:10). An immobilized lipase comprising Rhizomucor miehei is added to the mixture to effect preferential alcoholysis by shaking at 15-60 deg.C for 1-30hr, thus giving an ω-3 highly unsaturated fatty acid ester such as a docosahexaenoic ester.

In the calculation device 22, a clutch torque 24 is calculated by a formula: MKA = c.pMF. Here, MKA is a clutch torque, pMF is a pressure torque sensor and c is a coefficient. A clutch characteristic curve 32 is determined by another control device 30 in consideration to a standard value 28 of a control device 26. It is inspected whether or not a predetermined limit condition, for example, an accepted range against an engine revolution number or a predetermined minimum temperature is satisfied.
