Abstract: A heatsink is used with a fluid flow generator that rotates about a central axis extending vertically. The heatsink includes a main body section having a top surface facing the fluid flow generator in a vertical direction, and fins that extend upward from the top surface so as to define a plurality of flow passages. The plurality of flow passages form a plurality of fluid paths, each of which has an inlet for the fluid discharged from the fluid flow generator to flow in, and an outlet for discharging to outside the fluid that has entered through the inlet. At least one of the plurality of fluid paths has a first branch section for branching from a first fluid path on downstream of the inlet, and a first joining section for joining a second fluid path having another inlet, on downstream of the first branch section.

Abstract: A heatsink, which is used with a fluid flow generator that rotates about a central axis extending vertically to generate a flow of fluid, includes a main body section having a top surface facing the fluid flow generator in a vertical direction, and fins that extend upward from the top surface so as to define a plurality of flow passages. Four regions defined by an X axis and a Y axis, which cross each other at an intersection between the central axis and the top surface and extend in an extending direction of the top surface, are referred to as a first region, a second region, a third region, and a fourth region, in order in a direction opposite to a rotation direction of the fluid flow generator.

Abstract: In a digital-to-analog converter comprising a pulse-width modulation signal generator for generating a pulse-width modulation signal by pulse-width modulating an actual set value with a count value, and a low-pass filter for removing a high frequency component of the pulse-width modulation signal so as to output an analog signal, a difference between a current target digital value and a previous target digital value are multiplied by a coefficient determined from a time constant of the low-pass filter and a cycle of the target set value, and the multiplied value is added to the previous target set value so as to calculate the actual set value.

Abstract: A pneumatic tire comprises a tread with a plurality of sipes, in which one of opposed wall faces of the sipe is a concave face arc-shapedly curved over a whole of the sipe in a depth direction thereof and the other wall face thereof is a convex face just fitted to the above concave face, and a curvature of each of the concave and convex faces is substantially constant over a full length in a longitudinal direction of the sipe.

Abstract: The present invention relates to a gas collecting system collecting an inspection objective gas, such as a toxic gas discharged into an ambient air, and particularly to a gas collecting system which can achieve down-sizing of the system and permit implementation of analysis of gas concentration of the inspection objective gas at high precision with simple operation.

Abstract: The concentration of formaldehyde in air is measured by the method of the invention. More specifically, the invention relates to a method for analyzing formaldehyde in air by collecting the air and implementing an analysis of the concentration of formaldehyde at the site where such air is found.

Abstract: Level crossing number counter section 115 obtains the Doppler frequency caused by fading by counting the number of times of a received signal crossing an averaged received signal level. Corresponding to the Doppler frequency, reference signal correlation integration control section 116 controls reference signal correlation integration section 311 to suspend and restart the processing of integrating the correlation data of the received signal obtained in reference signal correlation section 306 with a reference signal.

Abstract: A system is disclosed for permitting a mobile telephone to recover an ongoing communication following a temporary interruption of operation, e.g., such as caused by an interruption of power to the mobile telephone, which includes circuitry and processor control to calculate the duration of the temporary interruption and for restoring synchronization of the mobile telephone to the mobile communication system. The circuitry stores synchronizing information prior to the temporary interruption and cycles synchronizing circuitry of the mobile telephone at a higher than normal cycling rate to restore synchronization of the mobile telephone with the mobile communication system. In a further embodiment, circuitry is disclosed for restoring the output of spread code generating circuitry in a spread spectrum digital mobile telephone to a phase used by a transmitting station of the mobile communication system.

Abstract: A CDMA communication system includes a base station and a mobile station. The base station transmits a first spread spectrum signal which contains information and a reference signal for synchronization. The mobile station receives the first spread spectrum signal from the base station. The mobile station includes a section for removing the reference signal from the received first spread spectrum signal and converting the received first spread spectrum signal into a second spread spectrum signal, and a section for despreading the second spread spectrum signal and recovering the information from the second spread spectrum signal.
