Title: Hammer
Inventor: MANAKA HIROSHI
IPC: B25D1/00
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a hammer which can drive a nail without bending the nail even though the nail is not held by another tool, and which can eliminate the necessity of always holding the nail by a hand during driving of the nail by the hammer so as to eliminate occurrence of a risk of hitting and damaging a finger by the hammer. SOLUTION: A concave 3 is formed in the hitting surface of a hammer. The concave hitting surface of the hammer can hold the head 7 of a nail within the concave 3 when the nail is driven by the hammer, and accordingly, the head can be prevented from coming out from the concave 3. Even though the nail 6 is slightly bent during driving of the nail 6, the head 7 of the nail is always held within the concave 3 so as to be prevented from coming out from the concave during driving of the nail with the hammer having the concave hitting surface. Thereby it is possible to prevent the nail from being bent during driving thereof.

Abstract: PURPOSE:To obviate generation of a welding defect with a method for providing a projection to one of galvanized steel sheets and welding said sheets by providing a specific hollow groove to the other galvanized sheet. CONSTITUTION:A projecting part 3 is formed to a steel sheet 1 in the case of welding the steel sheets 1, 2 which are galvanized 1a, 2a on one side. A doughnut-shaped circular groove 4 having the diameter larger than the diameter of the part 3 is provided to the sheet 2. The central parts of the part 3 and the groove 4 are matched and the sheets are welded. Then the part 3 is welded and a nugget 5 is gradually formed and flows into the groove 4. As a result, the welding current is uniformly conducted at the diameter range corresponding approximately to the size of the nugget, by which the welding conforming to the specification is accomplished without change in the current density.

Title: Thioindigo and production thereof
Inventor: YOSHINO MASAAKI
IPC: C09B7/00
Filed: 1985-06-10
Abstract: PURPOSE:To obtain thioindigo which exhibits photochromism, can form a monomolecular film and is suitable for use as an information recording material, by synthesizing thioindigo through a thiol by starting with a 12-25C long-chain alkylbenzene. CONSTITUTION:A 12-25C long-chain alkylbenzene is used as a starting material to synthesize a thiol therefrom by sulfonation, etc., and an indoxyl group is formed through a thioglycolic acid therefrom to produce a thioindigo of formula I or II (wherein R1, R2 are each a 12-15C alkyl). In the resulting thioindigo, a 12-25C long-chain alkyl group in the dye skeleton has hydrophobicity and the dye skeleton moiety acts as a hydrophilic group. Thus, a good monomolecular film can be formed at the interface between gas and liquid by an amphipathic action. An ultrathin film can be prepd. by Langmuir's project method.

Title: Air conditioner
Inventor: KOGURE HIROSHI
IPC: F25B1/00
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To improve abrasion resistance of a roller and a vane, improve reliability and save electric power by reduction of frictional resistance by forming a carbon element binder whose hardness is a specified value or more, and a film having a prescribed rate, on the outer diameter part of the roller as the contact part of the roller and the vane. SOLUTION: By contact friction of a roller 6 and a vane 7, surface preparation method such that hard film is formed on the surface of the roller 6 is carried out due to reduce outer diameter abrasion of the roller 6. Namely, when abrasion is generated on the outer diameter of the roller 6, high pressure gas is returned to a low pressure side in a cylinder 9, compression failure is generated, and then a function as a compressor is eliminated. Carbon atom binder whose hardness is 3000HV or more is stuck on the surface of the roller 6 about 0.5 to 2μm. The film is molded in such a way that hydrocarbon gas is decomposed by ark discharge plasma in high vacuum, and sticking is carried out. It is thus possible to improve abrasion resistance and lubrication resistance of the contact part of the vane 7, and it is also possible to save electric power by reduction of frictional force.

IPC: B65H3/52
Filed: 1982-07-21
Abstract: PURPOSE:To prevent multi-feed and skew feed of sheets by providing a multi- feed preventing member having at least two circular-arc outer peripheries of different radii. CONSTITUTION:A paper feeder is provided with a pick-up facility for a paper sheet P and a multi-feed preventing facility for the paper sheet P. The multi- feed preventing member 5 is oval, so that a point of contact with a pick-up roller 2 can be moved on the periphery near a fixed point. Thus, a fixed pressure and coefficient of friction can be always obtained at a point of contact of the pick-up roller 2 with the multi-feed preventing member 5. Therefore, the mechanism is simple, and paper sheets P can be easily supplied. Furthermore, at the time of feeding a paper sheet, the paper sheet P is reliably prevented from multi-feed and skew feed to stabilize performance and improve productivity.

Abstract: PURPOSE:To improve the heat radiation of a casting mold and to accelerate the unidirectional solidification of a super alloy by coating the powder of the lower oxide of titanium, more preferably the lower oxide of titanium which is blackened and has high emissivity on the outside layer part of a shell mold for casting. CONSTITUTION:Titanium is heated to about >=1,000 deg.C in a reducing atmosphere to release oxygen in TiO2 and to change the same to lower oxide, thereby yielding blackened TiO1.75-TiO1.65. The above-mentioned lower oxide is then coated on the outside layer of a casting mold with a binder consisting of butyl titanate and is calcined at a high temp. to complete an investment casting mold having the outside layer of high emissivity. The conversion to the lower oxide of titania can be accomplished in the process of manufacturing the casting mold as well. The heat radiatability of the titled casting mold is thus improved and the temp. gradient of the solid-liquid boundary during unidirectional solidification of the super alloy is increased and the crystal growth in the prior bearing direction of the alloy is accelerated.

Filed: 1988-05-24
Abstract: PURPOSE:To shorten the time required for driving an object to be moved to a target position by driving the object to be moved near to a reference position within the time after an off command of a main power supply is received before the main power supply is turned off. CONSTITUTION:The displacement conversion system is so constituted that a focusing lens is driven to the position of a step number 1 and the step number 2 of the target position is set as a present position when the processing operation of AF driving during processing of power off ends. The power supply is then turned off and the processing of the power off ends. The processing of lens resetting is, therefore, executed if the power switch is turned on again for the purpose of the next autofocusing action. An initial sensor 1 is turned on and 0 as the present position is set when one step driving in the opposite direction and weighting are executed once. The shortest flow of the lens reset is thereby selected and the subsequent autofocus driving control is rapidly started.
