A liquid discharge head includes a nozzle plate, a housing, a channel, and a positioning member. The nozzle plate has a nozzle hole and a first positioning hole penetrating through the nozzle plate in a thickness direction of the nozzle plate. The housing is bonded to the nozzle plate to form a single bonded body and has a second positioning hole extending in a thickness direction of the housing. A liquid flows through the channel between the nozzle plate and the housing to the nozzle hole. The positioning member fits into the first positioning hole and the second positioning hole to position the nozzle plate relative to the housing. A length of the positioning member is smaller than a sum of a length of the first positioning hole and a length of the second positioning hole in the thickness direction of the nozzle plate, and larger than the length of the second positioning hole.

A disk rotating device includes a flexible disk in which information is recordable, a turntable on which the disk is held, a spindle that rotates the disk held on the turntable, and a stabilizer that stabilizes the rotating disk. In the disk rotating device, a rotation transmitting device transmits the rotation of the spindle to the disk via the turntable, and a disk holding device holds the disk so that the disk is elastically deformable from a center of the rotation of the disk in a radial direction of the disk.

A method of molding an object with a mold having a transfer face includes the steps of filling, separating, re-melting, re-contacting, cooling, and removing. The filling step fills a thermoplastic material, having a temperature greater than a softening temperature of the thermoplastic material, into a cavity space in the mold having a temperature smaller than the softening temperature of the thermoplastic material. The thermoplastic material comes in contact with the transfer face and is cooled. The separating step separates the transfer face from the thermoplastic material to form a heat-insulating layer between the thermoplastic material and transfer face. The re-melting step re-melts the thermoplastic material with heat energy retained inside the thermoplastic material. The re-contacting step re-contacts the re-melted thermoplastic material to the transfer face. The cooling step cools the thermoplastic material to a temperature smaller than the softening temperature of the thermoplastic material. The removing step removes the cooled thermoplastic material from the mold.

A manufacturing method of a plastic laminate body, the plastic laminate body having at least one plastic laminate member that is laminated on a plastic substrate, which plastic substrate is pre-processed in advance so as to have a substantially final configuration, the manufacturing method includes softening the plastic laminate member when a transfer surface of a mold member, which is pre-processed in advance so as to have a desired configuration, is transferred to a surface of the plastic laminate member, so that an excessive part of the plastic laminate member is moved to an escape part which is pre-formed at the plastic substrate.
