摘要:
Piezo-electric assembly having a piezo-electric resonator of trapped energy type assembled within a forming case. A bulkhead within the case prevents manufacturing defects due to internal spreading of conductive paste, regardless of variations in the coating amount of the conductive paste in mass production or variations in the mount pressure. Constant clearance exists between the internal connecting portions of the external terminals and the draw-out electrode (input/output) electrodes of the resonator, so that any variation in the conductive paste coating amount or the mount pressure is compensated.

A PCS ECU 20 in a PCS system 10 calculates TTC which is a brake operation timing of a host vehicle, on the basis of the relative velocity Vr between the host vehicle and an object, a predetermined deceleration amount ΔV caused by a brake operation of the host vehicle, and a deceleration a caused by the brake operation of the host vehicle. Thereby, the deceleration amount ΔV caused by the brake operation of the host vehicle is to be a set constant amount regardless of the relative velocity Vr between the host vehicle and the object. Accordingly, it is possible to ensure the deceleration amount ΔV caused by a more appropriate brake operation.

A collision detection device which can determine in a short time a collision to each portion of a chamber member in the longitudinal direction thereof and which is highly reliable. A collision determination system (10) is provided with: a chamber member (20) which is disposed with the longitudinal direction thereof aligned with the vehicle width direction, has a pressure chamber (22) formed therein, and is provided forward of bumper reinforcement (14); a pair of pressure sensors (24) which is provided to the chamber member (20) at positions spaced from each other in the longitudinal direction thereof and outputs a signal corresponding to a variation in the pressure within the pressure chamber (22); and a collision determination ECU (26). The ECU (26) determines that a collision has occurred if the value of detection by either of the pair of pressure sensors (24) is greater than a first threshold value and, at the same time, the value of detection by the other of the pair is greater than a second threshold value which is set to be greater than the first threshold value.

A semiconductor memory device includes a memory cell array having plural memory cells that require a refresh operation when retaining data; a read/write control unit that performs read-access or write-access of memory cell address specified for the memory cell array based on instructions from the outside; a refresh control unit that performs hidden-refresh of memory cells without control from the outside; and a schedule control unit that makes the refresh control unit perform hidden-refresh after the read/write control unit read-accesses the memory cell array, and that also makes the refresh control unit perform hidden-refresh before the read/write access control unit performs write-access.
摘要:
A semiconductor memory device has: memory blocks; and a local bus connected to the memory blocks. Each memory block has: switches respectively provided between bit line pairs and the local bus and each of which is turned ON in response to a selection signal; a dummy local bus; first and second control circuits. The local bus and the dummy local bus are precharged to a first potential before a read operation. In the read operation, the first control circuit outputs the selection signal to a selected switch to electrically connect a selected bit line pair and the local bus, while the second control circuit supplies a second potential lower than the first potential to the dummy local bus. The first control circuit stops outputting the selection signal when a potential of the dummy local bus is decreased to a predetermined set potential that is between the first and second potentials.
