Title: Acceleration sensor
Inventor: TAKAHASHI JUHEI
IPC: G01P15/09
Filed: 1987-09-18
Abstract: PURPOSE:To obtain a sensor, from which voltage is hardly outputted even if temperature is changed, by fixing piezoelectric ceramics to a metal diaphragm, whose central part is fixed, constituting a vibrator, and providing an additional mass to the metal diaphragm. CONSTITUTION:A cabinet 1 and a base 2 are vibrated by acceleration, which is applied to a vehicle and the like. A metal diaphragm 4 and piezoelectric ceramics 5, which is fixed to the diaphragm 4, are deflected in proportion to the applied acceleration accompanied by the vibration. Since a load mass 9 is provided on the diaphragm 4, the deflecting amount becomes 3-10 times. The electric charge in the ceramics 5 is changed in proportion to the deflecting amount. The change is transduced into the change in voltage in an impedance transducer circuit 6. A voltage is obtained at an output terminal 8 through a filtering and amplifying circuit 7. Since the amount of the electric charge in the ceramics 5 is changed, the amplitude of the circuit 7 can be reduced. The proelectric effect of the ceramics 5 can be reduced substantially by that amount.

Abstract: PURPOSE:To improve the efficiency of information processing by dividing memory data divided for each page into plural memories for storage and at the same time adding buses to plural processors respectively so that these processors can access those data stored in memories at one time. CONSTITUTION:When a memory access request is received from a processor l-i, for example, a control processor 3 identifies a specific memory 2-j that receives access from memories 2-1-2-m based on the access address of the processor l-i. In case the selected memory j-2 receives an access request also from another processor l-k, control is carried out to secure the connection to the memory 2-j in response to the priority orders set to those processors respectively. At the same time, the connection is performed so that unequivocal correspondence is secured to the memories requesting the buses of each processor in case these processors give the access requests to different memories respectively. In such constitution, plural processors can give memory accesses at a high speed.
