Abstract: A method for producing a vial with low alkali elution by removing a deteriorated region caused by processing on an internal surface of a vial is disclosed. The method involves forming vials from borosilicate glass tubes including a first step of forming a borosilicate glass tube into a cup-shaped body by formation of a bottom of a vial, and a second step of forming the cup-shaped body into the vial by formation of a mouth of the cup-shaped body.

Abstract: Apparatus for manufacturing an injection needle having a hub and a cannula whose back end terminates within the hub. The apparatus includes a first subassembly jig for mounting the hub, inserting a cannula into a center hole of the hub, and securing the hub and cannula together with an adhesive. A silicone-containing-liquid is applied to the back end of the hub-cannula assembly. A second subassembly jig is provided for mounting the hub-cannula assembly to remove excess silicone-containing-liquid within the cannula, covering the front end with a cap, and housing the hub-cannula-cap assembly with a container. An opening of the container is sealed after the hub-cannula-cap assembly is removed from the second subassembly jig.

Abstract: A method for applying silicone oil to a back end of an injection needle having a hub with a center hole and a cannula inserting in the center hole, in which the cannula has a front end with a sharp bevel and a back end with another sharp bevel and the back end terminates within the hub. The method comprises allowing silicone-containing-liquid to continue to overflow at a constant rate of flow from a top end of a rising pipe having an inner diameter larger than an outer diameter of the cannula and an outer diameter smaller than an inner diameter of the hub, and concurrently dipping the back end into silicone-containing-liquid at the top end of the rising pipe. Silicone with no foreign matter can be applied to the injection needle while preventing adhesion of silicone containing liquid to the hub. The apparatus used for carrying out the method is also disclosed.

Abstract: A method of manufacturing an injection needle having a hub and a cannula whose back end terminates within the hub. The method comprises the step of mounting the hub on a first subassembly jig, inserting the cannula into a center hole of the hub, applying an adhesive to a bonding area of the hub and cannula, curing the adhesive, dismounting the hub-cannula assembly from the first subassembly jig, applying silicone-containing-liquid to the back end, mounting the hub-cannula assembly on a second subassembly jig removing excess amount of silicone-containing-liquid within the cannula, covering the front end with a cap, housing the hub-cannula-cap assembly with a container, dismounting the hub-cannula-cap-container assembly from the second subassembly jig, and sealing an opening of the container. The apparatus used for carrying out the method is also disclosed.

Abstract: A cover plate assembly for wall-mounted electrical wiring devices includes a plate frame disposed on a wall surface as surrounding a wall opening in the wall surface. The wall opening is provided to receive therein one or more electrical wiring devices such as switches. The plate frame has a window through which a portion of the wiring device extends outwardly. A face plate is placed over the plate frame to entirely conceal the same. The face plate is made from a plastic material and has a center opening through which a portion of the electrical wiring device is exposed to be accessible from outside of said face plate. Also included in the assembly is an under plate which is to be fixed with respect to the wall surface for holding said plate frame therebetween. The under plate is made from a flat metal stamping and secured to the rear of the face plate for reinforcement of the same.

Abstract: A delay switch comprising a delay element provided in the center of a body to produce a delayed output, a delay cam unit provided on one side of the delay element to start its actuation always from an identical position in response to the delayed output, and switching contact members electrically connected to terminals on other opposing sides of the delay element through the delay cam unit, realizing thus concurrently a constant delay time and a compact assembly.
