An energy-trapping thickness-shear resonator includes a piezoelectric substrate, a first electrode extending from a first end to a central portion of a first surface of the piezoelectric substrate and a second electrode extending from a second end to the central portion of a second surface of the substrate. Thus, the resonator utilizes thickness shear vibrations generated in a portion of the piezoelectric substrate located between the first and second electrodes at the central portion of the substrate. The width W of the la substrate is set to be equal to or less than about 0.7 mm and also to satisfy both of the following expressions (1) and (3) or to satisfy both of the expressions (2) and (3):(1) 0

An exposure apparatus exposes a substrate by projecting a pattern image onto the substrate through a liquid. The exposure apparatus includes a projection optical system by which the pattern image is projected onto the substrate, and a movable member which is movable relative to the projection optical system. A liquid-repellent member, at least a part of a surface of which is liquid-repellent, is provided detachably on the movable member, the liquid-repellent member being different from the substrate.

A latch is disposed turnably on a side door and becomes in a state of engaging with a striker disposed on a vehicle body. A ratchet engages with the latch by an engaging operation, and releases the engaging state by a disengaging operation. An open lever performs a door opening operation by the opening operation of an operating handle. A lever member is in contact with the latch in the engaging state, and excessively oscillates the latch in the direction of a closing operation, by which the engaging state between the latch and the ratchet is released during the time from the opening operation of the operating handle to the disengaging operation of the ratchet.

A door latch system of a motor vehicle comprises a latch unit mounted to the vehicle body. The latch unit has a latch condition to latch the door at a closed position and an unlatch condition to unlatch the door thereby to release the door. The system further comprises a power latch canceling mechanism mounted to the vehicle body. The power latch canceling mechanism includes an actuator that, when energized, enforcedly causes the latch unit to assume the unlatch condition. The system further comprises a manual latch canceling mechanism mounted to the vehicle body. The manual latch canceling mechanism includes a handle member that is placed at a position other than a vehicle cabin of the vehicle and a power transmitting member that transmits a movement of the handle member to the latch unit. The manual latch canceling mechanism causes the latch unit to assume the unlatch condition when the handle member is manipulated.

A step measuring method by which height distribution can be accurately measured in the case of exposing an object by a scanning exposure method, even when a plurality of areas having different heights due to steps exist in an asymmetrical distribution in a scanning direction on a surface of the object. Focus positions of same measuring points (26A, 26C) in a plurality of shot areas on a surface of a wafer (W) are measured, an inclination angle θxg of an reference plane (27) on the surface of the wafer (W) to an image plane (28) of a projection optical system is obtained, and the inclination angle of the wafer (W) is changed so as to offset the inclination angle θxg. Then, a shot area (SA7) to be measured is scanned to a measurement point row (32C) at the focus position, and the height distribution (step information) of the shot area (SA7) is obtained.

A composite vibration device includes a piezoelectric element defining a vibrating member, which is made of a material having a first acoustical impedance, first and second reflecting layers are connected to respective end surfaces of the piezoelectric element, each of the layers are made of a material having a second acoustical impedance lower than the first acoustical impedance, and first and second supporting members. Each of the first and second supporting members is made of a material having an acoustical impedance higher than the second acoustical impedance and is connected to the outer surface of each of the first and second reflecting layers. Vibrations propagated from the piezoelectric element are reflected at the interfaces between the reflecting layers and the supporting members.

A longitudinally coupled multi-mode piezoelectric filter is constructed to use a piezoelectric stiffened effect. The piezoelectric filter includes a multilayer piezoelectric element having at least four excitation electrodes arranged substantially parallel to one another and a plurality of piezoelectric layers which are arranged between the excitation electrodes and which are polarized in a predetermined direction. The piezoelectric filter further includes an input electrode, an output electrode, and a ground electrode. Application of an input signal between the input electrode and the ground electrode causes vibration of different order modes to be excited and coupled, such that an output signal is extracted between the output electrode and the ground electrode.

A vehicle door latch device comprises a one-motion door opening mechanism transmitting an opening movement of an inside open handle both to a lock lever and to a ratchet, an free-play type antitheft member, and a clutch mechanism provided between the one-motion mechanism and the inside open handle. The clutch mechanism is so connected to the antitheft member that the clutch mechanism is displaced to an uncoupling state where it does not transmit the opening movement to the one-motion mechanism when the antitheft member is changed over to a antitheft position, and that the clutch mechanism is displaced to a coupling state where it transmits the opening movement to the one-motion mechanism when the antitheft member is changed over to an antitheft cancelled position.
