A memory transistor and a select transistor are disposed side by side on a semiconductor substrate between source/drain diffusion layers thereof, with an intermediate diffusion layer interposed therebetween. The memory transistor includes: a gate insulating film having such a thickness as to allow tunneling current to pass therethrough; a floating gate electrode; an interelectrode insulating film; and a control gate electrode. The select transistor includes a gate insulating film and a select gate electrode. Tunneling current, allowing electrons to pass through the gate insulating film under the floating gate electrode, is utilized during the removal and injection of electrons from/into the floating gate electrode. As a result, higher reliability can be attained and rewriting can be performed at a lower voltage. Also, since the select transistor is provided, reading can also be performed at a lower voltage. Improvement of reliability and rewrite and read operations at respective lower voltages are realized for a nonvolatile semiconductor memory device, in which a memory cell includes a floating gate electrode and a control gate electrode.

A blow molding device includes a blow nozzle to be inserted tightly into a mouth tube section of preform when the preform is inserted in a mold. The blow molding device also includes a pressurized liquid feeding unit and feeds a pressurized liquid from the pressurized liquid feeding unit into the preform through the blow nozzle to form a container into an expanded shape along a cavity of the mold. A valve mechanism, provided at a downstream end of a feed channel for the liquid in the blow nozzle, can open and close the feed channel so that when the valve mechanism is in a closed state, the liquid circulates between the feed channel and the pressurized liquid feeding unit, and when the valve mechanism is in an open state, the pressurized liquid is fed through the feed channel into the preform.

A liquid-sealed vibration-proof device capable of avoiding leakage of liquid upon press fitting of an outer cylinder is provided. An intermediate ring interposed between the outer cylinder and an antivibratory base is formed at its outer circumferential surface with two projecting streaks, the one on liquid chambers side being formed with cutouts. When the outer cylinder is press fitted to an attachment opening of a vehicle body, the liquid confined in a space enclosed between both projecting streaks can escape to the liquid chambers, so that liquid never leaks outside.
