Title: Magnetic disk unit
Inventor: IMAI SATOMITSU
IPC: G11B25/04
Filed: 2000-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce air disturbance vibration of a head caused by airflow generated by the rotation of a disk. SOLUTION: Return channels 45a, 45b, 45c and 50 are provided so that the airflow, that flows a gap between a disk 11 and a shroud 41, goes through the back side of a voice coil motor and is bypassed to the downstream side of the rotational direction of the disk 11 of a load/unload mechanism 31. By guiding the airflow to the downstream side of the mechanism 31, generation of the disturbance of the airflow in the vicinity of the mechanism 31 is suppressed. Moreover, by providing a filter 60 in the return channel, the occurrence of disk flutter is also prevented.

IPC: H04W16/18
Filed: 2000-10-03
Abstract: PROBLEM TO BE SOLVED: To provide an electric field strength measuring device, capable of accurately measuring the field intensity off transmission data from a satellite and moreover producing measured data easy for statistical processing. SOLUTION: Transmission data from a satellite is received with a tracking antenna, of which the direction of the antenna is controlled automatically, so as to maximize the signal level of reception signal, and the intensity data is set (S210 to S240) to E=1, if the signal level is larger than a reference level and to set E=0, if the level is equal to or less than the reference level. If the intensity data have changed from the data set at the previous activation of the processing, the device transmits commands (S250 and S260) for changing the indication method of a running track and to a navigation controller for indication-processing the present position and the running track of the measured vehicle on a map.  Then GPS data, including the present position and its attributes of the position of the measured vehicle, are read (S270) from the navigation controller, and the device stores (S280), in turn, the measured data produced by correlating them with the field strength data.
