摘要： An engagement portion with a shape recessed in a radial direction of a sleeve is formed on an outer peripheral surface of the sleeve so as to circuit the outer periphery of the sleeve. The engagement portion is also disposed inside an assembly hole of a housing. Caulking of an area surrounding an opening of the assembly hole joins the engagement portion and a deformed portion of the housing. Parts such as sealing members and bushings become unnecessary, because the assembly hole and the sleeve are sealed by contacting surfaces of the deformed portion and the engagement portion. Furthermore, fixing of the sleeve and the housing, as well as the formation of a sealed portion between the assembly hole and the sleeve assures the realization of a one-time caulking process.

摘要： A method of stress inducing transformation from the austenite phase to the martensite phase by conducting cold working on material of austenite stainless steel in the temperature range from the point Ms to the point Md. The above cold working is a biaxial tensing. An intermediately formed hollow body is made, which includes a ferromagnetic portion and a non-magnetic portion contracting inward. Then, the intermediately formed body is subjected to a stress removing process in which residual tensile stress is removed from an intermediately formed body. In the stress removing process, it is preferable that a punch is press-fitted into the intermediately formed body so as to expand a non-magnetic portion and then the intermediately formed body is drawn with ironing while the punch is inserted so that the residual tensile stress can be changed into the residual compressive stress in the non-magnetic portion.

摘要： A solenoid valve has a tapered valve seat disposed between a first flow passage and a second flow passage, a reduced diameter side of the valve seat that is connected with the first flow passage, and a valve body having a closing portion that reduces its diameter toward a tip facing the valve seat. The first flow passage and the second flow passage are connected/disconnected by sliding the valve body for contacting/detaching the closing portion to the valve seat, and a groove is disposed on the closing portion facing the direction of a fluid flow.

摘要翻译： 通过在从Ms点到Md点的温度范围内对奥氏体不锈钢的材料进行冷加工，从奥氏体相转变为马氏体相的应力的方法。上述冷加工是双轴拉伸。 制成中间形成的中空体，其包括铁磁部分和向内收缩的非磁性部分。 然后，对中间成形体进行从中间成型体除去残留拉伸应力的应力消除处理。 在应力消除过程中，优选的是将冲头压入中间成形体中以膨胀非磁性部分，然后在冲压机插入时中间成形体被熨烫而拉伸，使得残余拉伸 应力可以变成非磁性部分的残余压应力。
