摘要:
A heat transfer system comprising a hydrogen supply unit 1, which transfers hydrogen from a hydrogen recovery tube 8 to a hydrogen supply tube 7, and a multiplicity of hydrogen utilization units 2A and 2B which utilize hydrogen supplied from the hydrogen supply tube 7 via its branching tubes 7a and 7b, respectively, and return hydrogen to the hydrogen recovery tube 8 via associated branching tubes 8a and 8b. By the use of the hydrogen supply tube 7 and the hydrogen recovery tube 8 having large volumetric capacities and filled with hydrogen, the hydrogen supply unit 1 and the hydrogen utilization units 2A and 2B may operate independently, without being synchronized one other.

A false twist yam including synthetic fiber yam having elongation, crimp rigidity, crimp appearance stretch ratio, dry heat shrinkage stress maximum value, deformation degree of single filament and entanglement number in specific ranges respectively. The yam has good drape properties, soft feeling, bulkiness, and flexibility as well as puff properties, mild luster, and pliable dry feeling. From the yam, woven or knit fabrics having novel texture that cannot be achieved in woven or knit fabrics produced from conventional drawn or false twist yams. The false twist yam is produced in a drawing and false twisting process.
摘要:
A method for stretch blow molding a preform into a hollow container having a heat-resistant property, including the steps of heat setting the hollow container by maintaining the hollow container heated for a predetermined period of time within a blow mold and cooling the hollow container by the use of a cooling medium blown out from the forward end of a stretching rod at least during backward movement of the stretching rod. If the heat setting operation is to be performed in a heat setting mold separately of the blow mold, the hollow container is cooled by the cooling medium blown out from the forward end of a cooling medium introducing rod while being moved. Since the cooling medium outlet is axially moved, the hollow container can be cooled uniformly, even if the hollow container has a particularly increased rate of longitudinal stretch. If a cooling medium introducing tube for introducing the cooling medium along the central axis of the rod is thermally insulated, any sweating and/or freezing on the rod can be prevented.

Disclosed is a glass material for press forming providing an optical element having a sufficient optical performance without surface cracks, cloudiness, scratches, and the like even when the glass material contains an easily reducible component. Also disclosed are an optical element having a sufficient optical performance without surface cracks, cloudiness, scratches, and the like and a method for manufacturing the same. Specifically disclosed are a glass material for press forming and a glass optical element each of which comprises a core portion composed of multiple component optical glass and a composite surface layer covering at least a region serving as an optical functional surface of the core portion. The core portion is composed of optical glass that contains an easily reducible component and does not contain Pb. The composite surface layer includes a first surface layer that covers the core portion and a second surface layer that covers the first surface layer. The first surface layer is composed of a component that does not react with the glass of the core portion at the press forming temperature and does not diffuse in the glass of the core portion. The second surface layer is composed of a component that improves formability during the press forming. Also specifically disclosed is a method for manufacturing the optical element.

摘要:
In input transition detection pulse generators used in semiconductor memory devices, etc., in order to permit a designer to arbitrarily design the power supply voltage dependency of an output pulse width in accordance with use, a scheme is employed such that the functional block for detecting transition of an input or inputs to generate a pulse signal or signals, or the functional block for setting the width of each pulse signal is caused to have a function to generate pulse signals having different power supply voltage dependencies of pulse widths to perform a predetermined logical operation by a logical operation unit on the basis of pulse signals from the input transition detection pulse generation block or the pulse width setting block, thus to output a pulse having a pulse width optimum for a power supply voltage used. In place of the logical operation unit, an approach may be employed to select any one of a plurality of units as the input transition detection pulse generation block or the pulse width setting block by using a control signal to output a pulse having any pulse width. Further, the input transition pulse generation block or the pulse width setting block may be constructed to set at least one pulse width of pulses generated therefrom on the basis of a delay time generated by using an RC delay line.
