IPC: B25J11/00
Filed: 1990-04-20
Abstract: PURPOSE:To nimbly operate the work object in a large weight with the sense similar to a hand work, by fitting a control grip via a force sensor to a wrist part, driving a holding device with the detection signal of the force sensor and providing a force detection means which detect the change of the force caused on the holding device at the part where the change thereof appears. CONSTITUTION:The size and direction of the force that an operator applies on a control grip 8 are detected by a force sensor 7 and the driving device of a motor, etc., is controlled so as to give the necessary movement to a holding device 12 according to this detection signal. In this case, the strength and direction of the force applied on the work object held on the holding device 12 are fed back to an operation side with their being detected by the force sensor 13 attached to the holding device 12. Consequently the operator can feel the force applied on the holding device 12 on the hand through a control grip 8.

Abstract: PURPOSE:To provide high corrosion resistance even under severe environment without degrading the beautiful silver white gloss that an aluminum hot-dipped steel plate posseses by forming a chromate film on said plate then treating the same with an org. silicone water repelling agent. CONSTITUTION:After a chromate film of 5-40mg/m<2> in terms of a content of Cr is formed on the surfaces of an aluminum hot-dipped steel plate, an org. silicone water repelling agent is applied on the top surface thereof by a spray method or the like. The treated surface is dried without rinsing, whereby the intended surface treatment is executed. Chromating treatments which are practised heretofore with Zn, Al or their metallic plated products are applicable to the chromating treatment in this case. For example, water repelling agents of silicone oil emulsion type are enumerated for the org. silicone water repelling agent. If the dry-treated film of the water repelling agent is 0.01-20mu thick, the purpose of this invention is fulfilled.

Abstract: PURPOSE:To obtain the adequate degree of turbulence and the degree of pressure loss corresponding to an oil temperature by a method wherein a shape memory alloy is utilized for a turbulator, the torsional degree of the turbulator is made variable corresponding to the oil temperature. CONSTITUTION:A turbulator 4 formed of a shape memory alloy is inserted into a heat transferring tube 1 through which an oil acting as a fluid is flowed. The shape memory alloy utilized in the turbulator 4 presents a spiral shape having a small torsional pitch during high temperature, accordingly, the turbulence of the oil is increased, thereby, the heat transfer coefficient of the inside is improved. On the other hand, when the oil is at intermediate temperature, a relatively large torsional pitch is obtained, further, when the oil is at lower temperature, the memory alloy becomes a belt-shaped plate 5, then the oil turbulence inside of the tube hardly appears, thereby, the pressure loss of the oil is decreased.
