An air cleaner is used in a two-stroke internal combustion engine to supply an air-fuel mixture passage and a fresh air passage in a carburetor with air cleaned by an air cleaner element. The air cleaner includes an air cleaner base having an air-fuel mixture opening communicating with the air-fuel mixture passage and a fresh air opening communicating with the fresh air passage, and an air guide member provided at the air-fuel mixture opening. The air guide member is configured to curve near the air-fuel mixture opening and extend from there along the air cleaner base, and has a cross section surrounded by a peripheral wall. The air guide member defines a mixture-use air extension passage for air to be added to prepare an air-fuel mixture air-fuel mixture, which extends from a first clean air intake to the air-fuel mixture opening. Blown-back gas from the air-fuel mixture passage hits against the inner wall of the curved portion of the air guide member, and is therefore restricted to flow out of the first clean air intake and leak into the air cleaner. Thereby, harmful emissions in the exhaust gas from the two-stroke internal engine can be reduced.

The wind power generator includes: a wind tunnel formed by a cylindrical member erected on a foundation in a vertical direction; a plurality of wind-collecting plates that extends from a circumferential wall of the cylindrical member in directions normal to the circumferential wall; a plurality of upper and lower guide plates provided between the wind-collecting plates; a plurality of wind inlets that introduces wind collected by the wind-collecting plates into the wind tunnel; back-flow preventing means that allow only the flow of wind blowing from the outside of the cylindrical member into the inside of the cylindrical member; a turbine that is driven by wind blowing out from one end of the wind tunnel, and power generator that is driven by the turbine.

A method and system for azimuth measurements using one or more gyro sensors is disclosed. The method includes acquiring a first data from each of the gyro sensors with an input axis aligned to a first angular orientation and acquiring a second data from each of the gyro sensors with the input axis flipped to a second angular orientation opposite to the first angular orientation. An earth rate component at the first angular orientations is determined based on a difference between the first data and the second data to cancel out bias of each of the gyro sensors. The method may include acquiring a third data of the gyro sensor with the input axis aligned to the same angular orientation as the first angular orientation. An average of the first data and the third data may be used instead of the first data for determining the earth rate component.

An article data reading apparatus having a first display 4 receiving operational entry from a customer or store clerk as an operator of the apparatus permits setting of operation mode to customer operation mode or store-clerk operation mode. In the customer operation mode, customer operation information relating to operations by the customer when a customer becomes the operator is displayed on the first display 4; in the store-clerk operation mode, store-clerk operation information relating to operations by the store clerk when a store clerk becomes the operator is displayed on the first display 4. Thus, read operability for both customer and store clerk can be improved.

A low profile card connector includes a connector housing, a cover member, a card storage space that is inserted with a card, a contact that is provided in a cantilever-like manner, a guide member that guides a face having a pad of the card, a retention member that guides a face having no pad of the card, and a contact displacement space in which the tip end of the contact is displaced. When a pad section has the nominal thickness “A” mm and the interval between the apex of the contacting section of the contact and the card rettention member is “C” mm, the contact displacement space has the thickness “F” mm that is set to be within a range of F=A−C+0.2 to F=A−C+0.5.

The base plate 31 of the connector housing is provided with the raised portion 50 that fits into one of the recessed portions 26 in the card 20 for the contact pads 27 when the card 20 is inserted. The raised portion 50 is made to function as a stopper to block the card from being inserted further when the card is wrongly inserted back to front, thereby preventing a possible deformation of the contact terminals on the connector side in the event that the card is wrongly inserted.

An IC card mechanism includes an IC card for insertion into a receiving space of an electronic device; a contact which is brought into contact with an external contact of the card when the card is inserted; a card pusher which is advanced, when the card is inserted, in an insertion direction of the card by being pushed by a front end face of the card, thereby accumulating resilient ejecting force; and a lock for locking, when the card is inserted, the card pusher in an advanced position and unlocking, when the card is pushed again in the direction of insertion of the card, the card pusher so that the card pusher is retracted by the resilient force and such that the card pusher, when retracting, pushes the front face of the card in a direction opposite to the insertion direction of the card, thereby allowing ejection of the card.
摘要:
The stopper portion that blocks the movement of the ejection member in the card ejection direction is disposed at the position which met in the width direction of card connector, and is in the position of the same side as the position with the elastic body 60 which urges the ejection member in the card ejection direction. This arrangement can hold the attitude of the ejection member straight relative to the connector, thus preventing troubles such as an inadvertent unlocking of the eject lock and an unstable contact between the contact pads of the card and the contact terminals of the connector.
摘要:
A ultrasonic vibration cutting tool which can optimize materials as in a separate type and can improve the transmission efficiency of ultrasonic vibration as in an integrated type. The ultrasonic vibration cutting tool comprises a ring-shaped projection and a blade essentially composed of diamond and held by the ring-shaped projection both of which are formed on the peripheral surface of a vibration conversion portion provided on a resonator, and the outer diameter of the blade is set larger than the outer diameter of the ring-shaped projection.
