Title: Sound collection device
Inventor: OBA RYOJI
IPC: G10K11/28
Filed: 1994-02-18
Abstract: PURPOSE:To measure a desired sound from a device with high accuracy by selecting a distance between an apex and an opening of the sound collection device to be a prescribed multiple of a focus so as not to be affected by surrounding environment noise even under a high noise level. CONSTITUTION:The sound collection device 1 is fixed with a handle 6 to direct an opening 3 of a sound collection hood 2 in a desired direction. A female thread is made to a tip 6a of the handle 6 to be mounted on a tripod. Then an acoustic bevel length L is selected to be a multiple of 10 of a focus (f) (L>=10.f). Thus, the hood 2 has a shape of long distance and the desired sound is collected by separating the sound from surrounding environment noise sounds. Furthermore, the sound is collected in the vicinity of the focus F and a microphone 10 is arranged to a position much deeper in the hood 2 much apart from the opening 3 and the disturbance in the sound field by the arrangement of the microphone 10 is reduced.

Title: Integrated controller for vehicle
Inventor: ODAKA KENJI
IPC: G01S13/93
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To conduct automatic braking control effectively in all road surface conditions for prevention of interference with steering by a driver, by controlling a steering actuator so as to cancel steering effort from a road surface side when a vehicle is discriminated as being in a steering condition from the road surface side. SOLUTION: The timing where the absolute value of a steering angle 8 exceeds its reference value is compared with the timing where the absolute value of steering torque T exceeds its reference value to discriminate if the latter is earlier than the former in timing. It is discriminated as a condition steered from road surface (wheel) side if the latter is earlier than the former, current is supplied to a motor 26 through a driving circuit 42 in a such a direction as to cancel detection torque T, thereby controlling driving of the motor 26. It is thus possible to conduct automatic braking control effectively in all road surface conditions. The control is limited to a case where a steering wheel 12 is rotated from the road surface side, therefore, it is possible to prevent interference with steering by a driver.
