The invention relates to a hollow injection-molding method of forming a hollow portion in molten resin in a mold cavity by introducing a pressurized fluid, and also to a pressurized fluid introducing and discharging apparatus therefor, and has an object of eliminating the backflow of the molten resin into a pressurized fluid passage. A gap between a cylindrical sleeve and a shaft core inserted into the sleeve is used as the pressurized fluid passage. The front end of the shaft core is projected into a mold beyond the sleeve front end to serve as a guide face. By sliding the shaft core, the state of an opening portion of the pressurized fluid passage in the side of the mold is changed between a narrowed state where the pressurized fluid can pass through the opening portion but the molten resin cannot enter the opening portion and a widened state allowing the pressurized fluid to rapidly discharge. The guide face allows the pressurized fluid to be reliably introduced into the mold cavity.

Provided is a positive electrode active material for a nonaqueous electrolyte secondary battery in which generation of gas resulting from a reaction between a lithium transition metal complex oxide and an electrolyte is suppressed even when the battery is stored at high temperature, thereby improving the reliability of the battery, suppressing deterioration of the lithium transition metal complex oxide, and suppressing the decrease in battery capacity. In the positive electrode active material, a compound containing zirconium and fluorine is attached to a surface of lithium cobaltate. This positive electrode active material can be produced by spraying a solution containing zirconium and fluorine onto lithium cobaltate while stirring lithium cobaltate.

In one embodiment, a method for removing a resist includes irradiating, with an UV light having a wavelength of less than about 240 nm, a structure having a resist on a pattern surface in an atmosphere having oxygen. The resist is used as a mask as it remains above the pattern after the pattern has been transferred to a magnetic recording medium surface having a magnetic film thereon, and the irradiating is performed during production of the magnetic recording medium. In another embodiment, a method for forming a magnetic recording medium includes applying a resist to a surface of a magnetic film above a substrate, curing the resist by irradiating the resist with first UV light to form a pattern, transferring the pattern to the magnetic film using the pattern, and removing the resist by irradiating using second UV light having a shorter wavelength in an atmosphere including oxygen.

摘要:
A printed circuit board connector is equipped with a housing and plurality of contacts. The housing has an insertion chamber 11 inserted by the mating-side connector, and a plurality of contact-insertion holes inserted by the contacts. The contact has a base portion, a contact-connecting portion that connects with a mating-side contact, and a lead portion that is solder-bonded to the printed circuit board. The base portion and the housing have a contact lance and level that engage with each other so that the contact does not move in an insertion direction to the contact insertion hole or a reverse direction, and the contact lance and level swingably hold the base portion inside the contact-insertion hole so that the lead portion approaches and separates from the printed circuit board surface.
