Title: Angular speed detector and acceleration detector
Inventor: OGAWA NAOKI
IPC: G01C19/5642
Filed: 1990-09-10
Abstract: PURPOSE:To obtain a angular speed and acceleration signals which are not affected by acceleration and Corioli's force by constituting the mechanical unit of a tuning fork member, vibration member, and stress detection member. CONSTITUTION:When acceleration is applied in the oscillation direction (y-y) of a tuning fork member 1, homopolar and same level stress detecting voltage are generated in piezoelectric elements 2 and 3, and the difference is zero even if acceleration is further applied. Therefore, taking the difference between the detected voltage of the elements 2 and 3, the differential voltage is affected by the acceleration applied to the vibration and the direction of the vibration of the member 1 caused by piezoelectric elements 4 and 5, angular speed can be known by this differential voltage. On the other hand, taking the sum of the detected voltage, sum voltage corresponds to the stress caused by vibration and acceleration, but is not affected by the stress cased by Corioli's force. If the affected quantity of vibration is subtracted from this sum voltage, the differential voltage becomes the acceleration applied in the direction of the vibration which is not affected by rotation and vibration.

IPC: H04L47/43
Filed: 1986-10-08
Abstract: PURPOSE:To minimize the increase in a storage circuit even if the number of stations is increased by using the storage circuit in common. CONSTITUTION:A detector 2 outputs detection information to a head address managing device 3. The head address management device 3, based on the information, supplies a head address to write a split packet signal into a storage circuit 1 to the 1st counter 4. When a packet end of a split packet sent from a station is reached, the detector 2 informs it to the head address managing device 3. Since the original packet signal is to be obtained by combining signals sent so far from the station, the head address managing device 3 sends the head addresses corresponding to the split packet signals stored so far with respect to the said station to the 2nd counter 5 sequentially in the stored order. The 2nd counter 5 sends the address signal of the 2nd counter area having the designated head addresses in the order of inputs to the storage circuit 1. The storage circuit 1 outputs the data included in each address sequentially from a terminal 1002.
