It is a method for producing a food-filled and sealed container having a high product value, in which a container lid made of resin is not deformed after sealing. In this method for producing a food-filled and sealed container, after a food is filled in a container body (10) made of thermoplastic resin, the container is sealed by heat sealing a container lid (20) made of thermoplastic resin, and the container body (10) and/or the container lid (20) have sealing surfaces (13, 24) provided with a concavity or convexity.

This aims to provide a press-apparatus mold capable of improving the yield of a blank while preventing wrinkles and cracks in a finished product, and an open-drawing method according to the press-apparatus mold. Within a range corresponding to the excess thickness portion (6) of a blank (4), the width of a punch (3) is gradually enlarged toward the end of the punch (3), thereby to curve boundaries (or the punch ridgelines (3d and 3e)) formed by the upper face (3a) and the side faces (3b and 3c) of the punch (3), toward the end of the punch (3) and to the widthwise outer sides of the punch (3). At the same time, the width of the recess (1a) of a die (1) is gradually enlarged toward the end of the recess (1a), thereby to curve a drawing profile (8) set by the punch (3) and the die (1), toward the ends of the punch (3) and the recess (1a) and to the widthwise outer sides of the punch (3) and the recess (1a).

A slide fastener slider with an automatic lock mechanism comprises a body including a support lug standing on a guide post, a guide lug standing at a rear opening side of the body, a recessed portion defined between the support lug and the guide lug, a pair of projections project from opposite sides of the recessed portion. A spring is mounted to the body with its V-shaped bent portion of the spring fitted into the recessed portion. The bent portion is then fixed by caulking the projections. A pintle of a pull tab is disposed on the spring. A pawl member, which has an pressing portion to be brought into resilient contact with the spring on its one end, the locking paws on the other end, and a support shaft at opposite sides of an intermediate portion thereof, is disposed on the pintle. The support shaft is axially supported on the support lug, the locking pawl side at a rear end of the pawl member is guided by the guide pawl, and the locking pawl is allowed to pivotally move for being fitted into and detached from the fastener elements by operating the pull tab. In the slider with the automatic lock mechanism, therefore, the pawl member and the spring can be easily disposed and assembled, and the pivotal movement of the pawl member can be guided on the locking pawl side.
摘要:
A powder coating composition includes one or more crystalline substances the lowest melting point of which is Mp and one or more non-crystalline substances the lowest glass transition point of which is Tg and is lower than Mp, wherein the crystalline and non-crystalline substances are selected from epoxy resins and curing agents and bonded to each other. The bonding is effected by maintaining a powdery mixture containing the crystalline and non-crystalline substances at a temperature higher than Tg but lower than Mp and the softening point of any of the the non-crystalline substances, optionally under a pressure, and cooling and pulverizing the resulting mixture.
摘要:
A process for producing a high-purity silica, which comprises the steps of reacting a crude silica with ammonium fluoride, acid ammonium fluoride or a mixture thereof in an aqueous medium to produce ammonium silicofluoride, separating the ammonium silicofluoride from an unreacted silica and impurities by the means of a solid/liquid separation, and reacting the thus-obtained ammonium silicofluoride with ammonia in an aqueous medium. This process is a low cost process, and enables to control properties of silica.

A bent metal body with a resin coating is fabricated by first applying a powder coating composition to a metal body to form a hardenable resin layer, then bending the metal body bearing the resin layer, and then hardening the hardenable resin layer to form the resin coating.
摘要:
A picture recording apparatus which can record a picture on a write-once medium having an element which specifies a first size on a recording area assigned to data saving in edit processing, and an element which subtracts the first size from a remaining amount of recording area in the write-once medium to calculate a second size secured for recording, characterized in that a recording size is managed using the second size as an upper limit of a recordable size, and that an editing area is secured using the first size as a lower limit.

In a light-emitting device and its manufacturing method, mounting by batch process with surface-mount technology, high light extraction efficiency, and low manufacturing cost are realized. The light-emitting device 1 comprises semiconductor layers (2, 3) of p-type and n-type nitride semiconductor, semiconductor-surface-electrodes (21, 31) to apply currents into each of the semiconductor layers (2, 3), an insulating layer 4 which holds the semiconductor layers (2, 3), and mount-surface-electrodes (5). The semiconductor layers (2) has a non-deposited area 20 where the other semiconductor layer (3) is not deposited. The insulating layer (4) has VIA 10 which electrically connect the mount-surface-electrodes 5 and the semiconductor-surface-electrodes (21, 31). In the manufacturing process, firstly. semiconductor layers (2, 3) and semiconductor-surface-electrodes (21, 31) are deposited on the transparent crystal substrate, and by using build-up process, insulating layer (4) and the mount-surface-electrodes (5) are formed, and secondly, VIA 10 are formed. and finally, the transparent crystal substrate is separated to get light-emitting device (1). Light can be extracted directly and efficiently from the semiconductor layers (2, 3). With the mount-surface-electrodes (21, 31), light-emitting device (1) can be mounted by using surface mount technology.
摘要:
To reduce influence of errors on the outer periphery side of a multi-layer recording disc, a first shifted middle area is assured at a predetermined position nearer to the inner periphery side than the last position of layer on the outer periphery side of a single-sided, multi-layer recording disc, and a second shifted middle area is assured at the position of layer that opposes the shifted middle area assured on layer. A recording layer extending from layer to layer may be shifted in the first and second shifted middle areas, and an area in which errors relatively readily occur on the outer periphery side of the first and second shifted middle areas may not be used.
