Title: Ultrasonic wave transmitter-receiver and its vibration control method
Inventor: ISHIMURA HIROSHI
IPC: H04R17/10
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To solve problems of a conventional broadband ultrasonic wave transmitter-receiver that has increased its size for a low frequency application and has had a structural difficulty in further broadening of the band because a lower limit frequency of the bandwidth corresponds to a longitudinal vibration resonance frequency. SOLUTION: A bending vibrator 15 consists of a piezoelectric thin plate ceramic 16 and a diaphragm 17 having a cavity 177 in its inside is fitted to a recessed part 10 provided to an upper face of a front mass 13 and joining parts are completely integrated by welding. Furthermore, in the case of applying a drive voltage to the piezoelectric thin plate ceramic 16, a phase shifter 19 is provided to shift a phase of the drive voltage. Thus, three vibration modes take place and they are combined to considerably extend the bandwidth. Moreover, the bending vibration mode of the entire bending vibrator 15 is set to a frequency lower than that of the longitudinal vibration mode of the transmitter-receiver to extend the bandwidth up to a low frequency region without increasing the size of the transmitter-receiver.

Title: Controller for hybrid vehicle
Inventor: NITTA TOMOAKI
IPC: B60L50/16
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To ensure traveling to a goal in safety while limiting output to a drive wheel even upon occurrence of an abnormality in a first control means for generally controlling respective control systems of the hybrid vehicle. SOLUTION: When an abnormality occurs in HEV-ECU system for generally controlling respective control systems, a T/M-ECU performs stop control in place of the HEV-ECU. An engine is stopped by an injector power supply stop signal (S332) and the controller for moor A is shifted to low speed constant rotation control by an abnormality control signal. Furthermore, the controller for motor B is controlled by means of an inhibiter switch and an accelerator switch at its inputs (S336, S337) and a lockup clutch is turned off to set the speed change ratio of a CVT at a specified value (neutral value) (S339).  According to the arrangement, a vehicle can be moved surely in safety to a goal while suppressing excess output by the limiting the output with the first motor on the sun gear side when the driving power of a second motor coupled to the ring gear side of a planetary gear is outputted from a carrier.
