Abstract: There is provided a copper alloy bonded body composed of a plurality of members made of an age-hardenable copper alloy, the members diffusion-bonded to one another. The copper alloy bonded body has undergone solution annealing and an aging treatment, the content of beryllium in the age-hardenable copper alloy is 0.7% by weight or less, and (i) a bonding interface between the members has disappeared and/or (ii) a bonding interface between the members remains, and an oxide film at the bonding interface has a thickness of 0 nm or more and 5.0 nm or less.

Abstract: A first epitaxial layer group to emit a yellow color light is provided on a substrate via a first buffer layer. Then, a second epitaxial layer group to emit a blue color light is provided on the first epitaxial layer group via a second buffer layer. The first and the second epitaxial layer group are made of II-VI semiconductor compounds, respectively.

Abstract: In a damping force control system for switching over a shock absorber in the suspension of a vehicle from a low damping force operation to a high damping force operation when a vehicle height difference exceeds a determinate limit value, the shock abosrber is switched over from the low damping force operation to the high damping force operation after the lapse of a delay period so that the shock absorber is continually maintained at the high damping force operation from a time point at which the vehicle height difference generally reaches a peak amplitude of its variation for a time duration which is increased as a peak amplitude of the vehicle height difference exceeding the determinate limit value increases.

Abstract: In a damping force control system for switching over a shock absorber in the suspension of a vehicle from a low damping force operation to a high damping force operation when a vehicle height difference exceeds a certain limit value, the frequency of the vehicle height difference exceeding the certain limit value is counted for each certain cycle period, and the shock absorber is controlled to provide the high damping force operation for a time duration in each cycle period, the ratio of the time duration to the cycle period being varied in accordance with the frequency so that the ratio is increased along with an increase of the frequency.

Abstract: A sterilizing apparatus for sterilizing a hollow prism-shaped carton open at both ends includes a sterilizing station, a drying station, and a solution-removing station located between the sterilizing station and the drying station. The solution-removing station has a solution-removing device which rotates intermittently in synchronism with carton conveyers. The solution-removing device includes a plurality of thin and long mandrels extending in a radial direction and spaced apart from each other at regular intervals. Each mandrel supports a carton and has a nozzle which supplies the aseptic air from an aseptic air source into the carton.
