摘要:
A mold device and a method of manufacturing a cylinder block. The mold device comprises a split core having two first split cores formed so that the tip parts thereof may be in a tapering shape, two second split cores installed between the first spilt cores, and an inner core is installed at the center part and pushing out the first split cores in the direction receding from the center axis thereof. When the inner core is pushed out to push out and position the first spilt cores, both end parts of the second split cores are brought into contact with the tip parts of the adjacent first split cores, and the outer side-faces of the first split cores and the outer side-faces of the second split cores form a cylindrical shape. When the inner core is raised, the first split cores and the second split cores are pulled to the axial center by first engagement pieces and second engagement pieces.

A method of manufacturing a cylinder block using a die apparatus wherein a columnar hole includes a bore in the cylinder block. The method includes the steps of abutting first and second split cores against an upper surface of a distal end core, the upper surface being located opposite the inner core, and introducing a molten metal into a cavity. An inner core is withdrawn to move the first and second split cores toward an axis. The first and second split cores are released from a formed product made of solidified molten metal. The split cores are removed from the formed product to form the bore, and an inner surface of the bore is cut.

In a transmission system capable of measuring packet loss ratio between arbitrary devices upon a transmission path without increasing bandwidth of an OAM frame band, a plurality of transmission devices which have been disposed upon a transmission path are provided with a frame analysis unit which receives data frames so as to analyze the type of the data frames, a count processing unit which stores the number of received frames included in the data frames into storage module provided beforehand, an output line end portion which outputs the data frames, and an OAM processing unit which calculates the packet loss ratio in the transmission path using the number of received frames. The frame analysis unit has a function which, if the data frames are OAM frames, copies the data frames and the OAM processing unit has a function which calculates the packet loss ratio using the copied OAM frames.

In a hybrid integrated circuit device of the present invention, leads are fixedly attached on the upper surface of a circuit board. The lead includes an island portion, a slope portion, and a lead portion. A transistor and a diode are mounted on the upper surface of the island portion. Electrodes provided on the upper surfaces of the transistor and the diode are connected to a bonding portion through a fine metal wire. The bonding portion of the lead is disposed at a higher position than the island portion. Thus, the fine metal wires connected to the bonding portion are separated from each other.

A system measures delivery quality of data packets transmitting from a communication device to at least one communication terminal through a multicast network. The system includes a communication section for periodically transmitting a first packet to a communication terminal and receiving a second packet in response to the first packet from the communication terminal. The second packet includes delivery quality information. The system further includes a measuring section for measuring the delivery quality of data packets based on the delivery quality information.

A coating system for forming a protective layer includes first through fourth robots which are controlled by a controller and are provided close to a transport line, and sprayer mechanisms provided on ends of arms of the first through fourth robots. The motions of first through fourth robots are taught. Liquid material including an acrylic copolymer is sprayed onto an object such as a vehicle body, and dried to form a peelable protective layer on the object. The liquid material is sprayed from a first through fifth sprayers of the sprayer mechanism after the vehicle body is painted. At this time, the liquid material from the first sprayer is distributed locally in the smallest area. The area where liquid material is sprayed becomes wide gradually, in the order of the third sprayer, the fourth sprayer, the fifth sprayer, and the second sprayer. Such sprayers are also arranged in this order from an edge of the vehicle body.

Cooling liquid flowing through cooling-liquid passages cools in heat-transmission manner an inner layer on an inner surface of an impermeable intermediate layer and is directed through a piping to an interface between the intermediate and outer layers, whereby the porous outer layer is cooled by latent heat generated by evaporation of the cooling liquid infiltrated into the porous outer layer.

An absorbent article including a liquid permeable outer material, a liquid impermeable antileakage material, and a liquid retentive absorbent element interposed therebetween, and formed in a generally vertically elongated shape, the improvement including a pair of fixing elements extending outwardly in a width direction from both longitudinal edges of the absorbent article, each of the fixing element being provided on at least a back side thereof with a first adhesive portion having no separate paper, the pair of fixing elements being able to be adhered to and separated from a back side of the absorbent article through the first adhesive portions.
摘要:
An absorbent article comprises a liquid-permeable surface sheet, a liquid-impermeable leak-proof sheet and an absorbent layer disposed between the two sheets, said leak-proof sheet having on the outside surface a composite comprising a hydrophobic polymer having a glass transition temperature of zero degree centigrade or lower and foamed beads of a polymer. It is improved in the anti-slipping property, the leak-proof property and the permeability to moisture.
