Abstract: A shuttlecock including a cap and a skirt part whereto an air passage hole is formed, wherein a rib is provided to the skirt part, adjacent to a rear end of the air passage hole in a generatrix direction of the skirt part, the rib having a shape wherein air pressure difference is generated between an air flow passing through the air passage hole to flow on an inside of the rib and an air flow not passing through the air passage hole but to flow on an outside of the rib, and an aerodynamic force directed from the inside of the rib to the outside is generated.

Abstract: It is a objective of the present invention to provide a control apparatus which is capable of compensating a delay time for opening a pressure reducing valve since an electronic control unit sends a command signal for driving the pressure reducing valve so as to discharge high pressure fuel in a fuel accumulating device of a fuel injection system for the internal combustion engine. The delay time control apparatus for opening a pressure reducing valve has a potential for avoiding an overshoot phenomenon in which an actual pressure of fuel accumulated in the fuel accumulating device overshoots a target value of fuel pressure during the increase the fuel pressure of the fuel accumulating device.

Abstract: There is disclosed an inspection device of a plugged honeycomb structure in which a plugged honeycomb structure is an inspection target, and the inspection device comprises a light source which illuminates one end face of the plugged honeycomb structure as the inspection target; a camera-side lens which condenses light emitted from the light source to the one end face, transmitted through plugged portions of the plugged honeycomb structure and radiated from the other end face; a camera which receives the light condensed by the camera-side lens; and an image processor which processes an image of the light received by the camera to display the contrast of the light transmitted through the plugged portions of the plugged honeycomb structure.

Abstract: An inspection method of a honeycomb structure comprises the steps of illuminating one end face 15 of a honeycomb structure 11 as an inspection target by a light source 1; condensing, by a condensing lens 2 as a lens having an angle of view, light which is emitted from the light source 1 to the one end face 15, passed through cells of the honeycomb structure 11 and radiated from the other end face 16; receiving the light condensed on the condensing lens 2 by a camera 3; subjecting the light received by the camera 3 to image processing by an image processor 4, thereby specifying the radiated position of the light on the other end face 16; and calculating the tilt of the cells 14 of the honeycomb structure 11 from the radiated position of the light on the other end face 16, and the direction of the tilt.

Abstract: A control unit executes sensing of a fuel property of fuel based on a physical value, which is related to a combustion state of the fuel in an internal combustion engine, when it is determined that a predetermined prerequisite operational condition for the sensing of the fuel property is satisfied upon occurrence of at least one of consumption of a predetermined amount of fuel, traveling of a vehicle through a predetermined travel distance, and execution of a predetermined number of operation cycle(s). The predetermined prerequisite operational condition may be satisfied when an operational state of the internal combustion engine is a deceleration fuel cut-off state or an idle state.

Abstract: Provided is a thin film piezoelectric resonator which includes a piezoelectric resonator stack (12) having a piezoelectric layer (2), an upper electrode (10) and a lower electrode (8); and a substrate (6) which supports the piezoelectric resonator stack. The piezoelectric resonator stack (12) is provided with a vibration region (18) wherein the upper electrode (10) and the lower electrode (8) face each other through a piezoelectric layer (2) and primary thickness vertical vibration can be performed; and a supporting region (19) supported by the substrate (6). The vibration region (18) has an oval shape with a ratio a/b of 1.1 or more but not more than 1.7, where (a) is a long diameter and (b) is a short diameter. The piezoelectric resonator stack (12) is further provided with an upper dielectric layer (20) formed on the upper electrode (10).

Abstract: An internal combustion engine control device has a torque increase amount obtaining section that obtains engine rotation speed fluctuation amount (output torque increase amount) caused with small quantity injection as a torque increase amount sensing value, an adaptation value setting section that variably sets an adaptation value used for engine control in accordance with a fuel property determined based on the torque increase amount sensing value, a confirmation injection control section that performs the small quantity injection again while the engine control is performed based on the set adaptation value, and an accuracy determination section that determines accuracy of fuel property determination result or the adaptation value based on whether a confirmation sensing value, which is the engine rotation speed fluctuation amount obtained when the confirmation injection control section performs the small quantity injection, is outside a predetermined range.

Abstract: A solenoid-operated valve device is provided which includes a valve, a solenoid actuator designed to be supplied with electric power from a battery to operate on voltage substantially identical with that outputted from the battery to move the valve, and a controller working to energize said solenoid actuator. Prior to entering a main energization mode to energize the solenoid actuator to open or close the valve, the controller works to supply a low current to the solenoid actuator to create magnetic field therein to assist in energizing the solenoid actuator in the main energization mode quickly at a high speed. The controller may alternatively be designed to step-up the voltage to be applied to the solenoid actuator initially prior to entering the main energization mode.
