Abstract: A heat sink includes: a container having a cavity inside and a first surface and a second surface opposite the first surface; a working fluid encapsulated in the cavity; and a steam flow path in the cavity where the working fluid in a gas phase flows, the first surface having a flat part and a protruding part projecting from the flat part in an external direction, causing the container to have a flat portion and a protruding portion projecting from the flat portion in the external direction, an inner space of the protruding portion of the container being in communication with an inner space of the flat portion, causing the cavity to be formed, and a first heat radiating fin being provided on an exterior of the flat part of the first surface and a second heat radiating fin being provided on an exterior of the second surface.

Abstract: Provided is a method for predicting the remaining life of a hose and a method for diagnosing the deterioration level of a hose that can be easily performed without breaking the hose. The disclosure includes: a testing step of performing a hose bending test; and a predicting step of predicting the remaining life of a hose subject to prediction, wherein during the hose bending test, either a value of an external force required to displace a hose portion in a direction of the external force by a predetermined displacement amount, or a value of a displacement amount in a direction of the external force of the hose portion when the external force of a predetermined magnitude is exerted on the hose portion is measured, and the measured value is obtained as the test result.

Abstract: A method of driving an information display panel: in which display media constituted by particles including charged particles are sealed between two substrates, at least one substrate being transparent; in which the display media, to which an electrostatic field is applied, are made to move so as to display an information image; and in which, after an erasing wherein a color is displayed on a whole screen is performed, a rewriting of an information display is performed in such a manner that a color at the erasing is changed by applying a voltage forming electrostatic field in a reverse direction as that at the erasing, is characterized in that, after the rewriting of the information display is finished, a voltage forming electrostatic field in the same direction as that at erasing is applied.

Abstract: A seismic isolation apparatus features damping characteristics equivalent to or better than prior art, without burdening the environment. In this seismic isolation apparatus, a cylindrical cavity portion is formed at the middle of an outer side laminated body, which has a form in which respective pluralities of resiliently deformable rubber rings and metal rings for maintaining rigidity are alternately laminated. A helically formed coil spring is disposed in this cavity portion so as to be snugly fitted. An inner side laminated body, which has a form in which respective pluralities of resiliently deformable rubber plates and metal plates for maintaining rigidity are alternately laminated, is disposed at an inner peripheral side of the coil spring.

Abstract: A controller in which proportional integral (PI) arithmetic is effected on a deviation between a measurement or process signal from a process or controlled system and a control set value, and a resultant manipulation signal is outputted to the process. A waveform of the process signal or the deviation signal is observed. PI arithmetic parameters undergo self-tuning so that the measurement result becomes a preset response target.
