A piezoelectric device is provided and includes a substrate, a first electrode film, a piezoelectric film, and a second electrode film. The first electrode film is formed on the substrate. The piezoelectric film is represented by Pb1+X(ZrYTi1−Y)O3+X(0≦X≦0.3, 0≦Y≦0.55) and a peak intensity of a pyrochlore phase measured by an X-ray diffraction method is 10% or less with respect to a sum of peak intensities of a (100) plane orientation, a (001) plane orientation, a (110) plane orientation, a (101) plane orientation, and a (111) plane orientation of a perovskite phase, the piezoelectric film being formed on the first electrode film with a film thickness of 400 nm or more and 1,000 nm or less. The second electrode film is laminated on the piezoelectric film.

To ensure that an energy supply operation can be performed safely and smoothly on a vehicle having a plurality of energy ports such as a charging port, charging ports for supplying electric energy to a high voltage battery and a fuel supply port for supplying fuel to a fuel tank are provided in a vehicle body as energy supply ports. The fuel supply port and charging ports are respectively provided with lid members that are switched between a closed state and an open state by respective lock mechanisms. When closure of one lid member is released, all of the other lid members are prohibited from being switched to the open state, and therefore the number of energy supply ports having an open lid member is limited to one.

There is a need for a piezoelectric element capable of improving a productivity and a yield without impairing the piezoelectric characteristic and a method for manufacturing the same. A piezoelectric element is provided with a substrate, a first electrode film disposed on the substrate, a piezoelectric film disposed on the first electrode film, and a second electrode film disposed on the piezoelectric film. The piezoelectric film has a laminated structure composed of a plurality of crystallized piezoelectric thin films. The piezoelectric film having a predetermined thickness is formed by repeated cycles of a film formation step of forming a piezoelectric thin film and a crystallization heat treatment step of heat-treating the piezoelectric thin film to effect crystallization. In this manner, a piezoelectric film exhibiting uniform crystallinity in the film thickness direction may be produced.

A drive electrode to which a voltage for allowing a vibrator to vibrate is applied and first and second detection electrodes extending in the longitudinal direction of the vibrator in parallel to each other are formed as the upper electrode such that the drive electrode is interposed between the first and second detection electrodes and does not contact with the detection electrodes. In the case where there is a difference between the detection signals detected in the first and second detection electrodes when a voltage is applied between the lower electrode and drive electrode to allow the vibrator to vibrate at a vertical resonance frequency, a laser light is irradiated to a desired portion of the vibrator to apply grinding operation based on detection signals detected in the first and second detection electrodes, thereby adjusting the shape of the vibrator.

A semifinished flat tube 30 is for use in producing a flat tube 1 comprising an upper and a lower wall 2, 3 opposed to each other, and left and right opposite side walls 4, 5 interconnecting the upper and lower walls 2, 3 at opposite side edges thereof. The semifinished flat tube is produced from a metal plate 15 having two flat first portions 17, 18 for making the upper and lower walls 2, 3, a second portion 16 interconnecting the two first portions 17, 18 integrally for forming the right side wall 5, and two third portions 9, 10 projecting upward from the respective first portions 17, 18 integrally with the first portion each at a side edge thereof opposite to the second portion 16 for making the left side wall 4, by bending the metal plate 15 to the shape of a hairpin at the second portion 16 to cause the third portions 9, 10 to butt against each other. The two third portions 9, 10 arc joined to each other by laser welding intermittently from outside at a plurality of portions spaced apart longitudinally thereof.

The evaporator includes the upper side and lower header members 10 and 50 disposed at the upper and lower end of the core 1. One end of each tube 6 constituting the upstream-side tube group P1 is connected to the inlet-side tank 11, while the other end to the lower header member 50. One end of each tube 7 constituting the downstream-side tube group P2 is connected to the outlet-side tank 12, while the other end to the lower header member 50. The refrigerant flowed into the inlet-side tank 11 is introduced into the outlet-side tank 12 by passing through the upstream-side tube group P1, the lower header member 50 and the downstream-side tube group P2, so that the refrigerant evaporates by exchanging heat with ambient air A. Accordingly, it improves the heat exchange performance and decreases the thickness.

Disclosed is a display control device for a touch panel-type setting-operation unit, which is designed to display a plurality of manually operable keys on a display screen and to perform an input processing corresponding to the operation of one or more of the keys. The display control device is operable, based on an evaluation value representing the operational status of each of the keys, which is derived from the relative operation number of each of the keys in a given period of time, to vary the respective display colors of the display areas for the keys in a stepwise manner using a color gradation from a color with high visibility to a color with low visibility in the order of higher score of the evaluation value.

In a vehicle glove box including a main body provided movably to an instrument panel, a lid portion provided to the main body on the interior side and forming a closed section with a surface of the main body on the interior side, and a reinforcing member of a substantially plate-like shape extending across the closed section in the width direction of the main body, a plurality of support portions provided to the main body on the interior side in the form of protrusions which extend toward the interior. These support portions support a peripheral surface of the reinforcing member, so that the reinforcing member can be thus provided to the main body to form an integral structure. In this way, it is possible to provide the glove box which can be assembled through a simple and easy assembling process and thereby reduce the burden to an operator.

In a tray feeder, in which a drawing section draws a palette from a container and supplies the palette to a pick-up point where a pick-up head of a parts-mounting-apparatus picks up parts, the head starts lowering and halts at a stand-by position before the palette held by the drawing section arrives at the pick-up point. When the drawing section arrives at the pick-up point, the head lowers again from the stand-by position. This mechanism reduces a time necessary for picking up a part.
