Patent number: 6249073Abstract: A flexural-mode, micromechanical resonator utilizing a non-intrusive support structure to achieve measured Q's as high as 8,400 at VHF frequencies from 30-90 MHz is manufactured using polysilicon surface micromachining technology. Also, a method for extending the operating frequency of the resonator as well as other types of micromechanical resonators is disclosed. One embodiment of the method is called a differential-signaling technique. The other embodiment of the method is called a dimple-down technique. The support structure includes one or more torsional-mode support springs in the form of beams that effectively isolate a resonator beam from its anchors via quarter-wavelength impedance transformations, minimizing anchor dissipation and allowing the resonator to achieve high Q with high stiffness in the VHF frequency range. The resonator also includes one or more spacers in the form of dimples formed on the flexural resonator beam or the substrate.Type: GrantFiled: January 13, 2000Date of Patent: June 19, 2001Assignee: The Regents of the University of MichiganInventors: Clark T. -C.

Patent number: 6244243Abstract: A control device for controlling a direct injection engine provided with an injector for injecting fuel directly into a combustion chamber in a cylinder thereof and a throttle valve is switchable between a stratified charge combustion mode and a uniform charge combustion mode. The control device predicts switching to the uniform charge combustion mode based on a change in the target load Piobj during engine acceleration in the stratified charge combustion mode, and corrects the target load Piobj so that the opening of the throttle valve approaches the opening suited for the uniform charge combustion mode prior to the switching to the uniform charge combustion mode when such combustion mode switching has been predicted. This control device prevents torque shock due to the combustion mode switching during engine acceleration without causing a deterioration in fuel economy or in vehicle acceleration performance.Type: GrantFiled: January 11, 2000Date of Patent: June 12, 2001Assignee: Mazda Motor CorporationInventors: Kiyotaka Mamiya, Michihiro Imada, Masayuki Tetsuno
