Abstract:
A piezoelectric gas jet generator includes a piezoelectric vibrator and upper and lower volume-varying chambers formed above and below the piezoelectric vibrator. In order to effectively use the movement of air supplied with the vibration of the piezoelectric vibrator, plural upper supply pipes and lower supply pipes communicating with the upper and lower volume-varying chambers and protruding from an upper housing and a lower housing are made to protrude in a direction parallel to the plane of the piezoelectric vibrator so as to be parallel to each other. Here, the upper supply pipes and the lower supply pipes are located at different planar positions.
Abstract:
A diaphragm air pump includes a diaphragm; and upper and lower housings that interpose the diaphragm such that a variable volume chamber is formed over and under the diaphragm. The diaphragm air pump vibrates the diaphragm to obtain a pump operation, a circular concave portion into which the diaphragm that is circular in plan view is fitted is formed in any one of the upper and lower housings, a ring-shaped groove for housing a seal member is formed in the other, the ring-shaped groove having inner and outer diameters which are set across the circular concave portion, and a ring-shaped elastic seal member which is compressively deformed across the periphery of the diaphragm by the upper and lower housings is housed in the ring-shaped groove.
Abstract:
Exemplary embodiments provided a conductive paste including an organic gold compound and a glass component in a solvent. When electrodes are formed on both surfaces of piezoelectric members using the conductive paste according to the invention, it is possible to improve the close adhesion property between the electrodes and the piezoelectric members eliminate ion migration, and lower electric resistances of the electrodes.

Abstract:
An exhaust gas treatment device for preventing a large quantity of unburned HC components from being released to the outside until a diesel oxidation catalyst reaches an activation temperature after early post-injection. By reducing a throttle opening of a variable throttle mechanism (77) provided in an oil passage (72), or increasing a set value of an oil pressure level detected in an oil pressure sensor (78) provided on the downstream side of the variable throttle mechanism, power of an oil circulation pump (74) is increased before a start point t1 of the early post-injection. With this arrangement, by increasing a load of a diesel engine to increase a temperature rise gradient of exhaust gas at the stage of increasing the temperature of the diesel oxidation catalyst, the unburned HC component released until the diesel oxidation catalyst reaches the activation temperature is reduced.
Abstract:
An image processing apparatus capable of improving the usability in search by, for a person presumed to be difficult to be misidentified, improving the frequency of identifying the person. When calculated degree of similarity is equal to or greater than a threshold, it is identified that a face of the person corresponds to a face of any one of registered persons. The threshold is set to a second value greater than a first value, for the face of one of the registered persons who has not been identified when starting recording of the image, and the threshold is set to a third value between the first value and the second value, for the face of one of the registered persons who is already identified when starting the recording of the image, after the recording of the shot image to the nonvolatile recording medium is started.
Abstract:
Reliability of a semiconductor device is improved. In a flatness inspection of BGA (semiconductor device), there is formed a flatness standard where a permissible range in the direction of (+) of flatness at normal temperature is smaller than a permissible range in the direction of (−). With use of the above flatness standard, a flatness inspection of the semiconductor device at normal temperature is performed to determine whether the mounted item is non-defective or defective. With the above process, defective mounting caused by a package warp when heated during reflow soldering etc. is reduced and reliability of BGA is improved. At the same time, flatness management of a substrate-type semiconductor device with better consideration of a mounting state can be performed.
Abstract:
An object is to prevent a large quantity of unburned HC components from being released to the outside until a diesel oxidation catalyst reaches an activation temperature after early post-injection. In the present invention, by reducing a throttle opening of a variable throttle mechanism 77 provided in an oil passage 72, or increasing a set value of an oil pressure level detected in an oil pressure sensor 78 provided on the downstream side of the variable throttle mechanism 77, power of an oil circulation pump 74 is increased before a start point t1 of the early post-injection. With this arrangement, by increasing a load of a diesel engine 10 to increase a temperature rise gradient of exhaust gas at the stage of increasing the temperature of the diesel oxidation catalyst, the unburned HC component released until the diesel oxidation catalyst 50 reaches the activation temperature is reduced.
Abstract:
