摘要:
A shift control system includes a belt-type continuously variable transmission (CVT) with primary and secondary pulleys, a shift actuator that regulates an oil pressure supplied to the primary or secondary pulley to vary an actual transmission ratio of the CVT, and a control unit that controls the shift actuator. The control unit sets a target transmission ratio in a first mode when a normal driving range is selected and in a second mode when an engine braking range is selected, drives the shift actuator to adjust the actual transmission ratio to the target transmission ratio, determines a delay time to delay the setting of the target transmission ratio in the second mode at the time of range switchover from the normal driving range to the engine braking range, and holds the target transmission ratio set in the first mode until the delay time has elapsed from the range switchover.

There is provided a V-belt continuously variable transmission (10) including: a primary pulley (11) that is connected to an input shaft (11d); a secondary pulley (12) that is connected to an output shaft (12d); a V-belt (13) that is wrapped around the primary pulley (11) and the secondary pulley (12); and controllers (20, 30). When a speed ratio of the transmission (10) is to be increased, the oil pressure supplied to the primary pulley (11) is set to an oil pressure necessary for ensuring a torque capacity of the V-belt (13) and necessary for maintaining the speed ratio, and the oil pressure supplied to the secondary pulley (12) is set to an oil pressure that is higher than the oil pressure necessary for ensuring the torque capacity of the V-belt (13) and necessary for maintaining the speed ratio, thereby attaining a target speed change speed.

A lighting method for a high pressure discharge lamp in which a high-pressure pulse is applied to cause a dielectric breakdown, and then in step S1, it is judged whether the lamp voltage is higher than 25 volts as the current switching voltage. If it is judged negatively in step S1, the control circuit 304 performs a constant current control with the current limiting level set to 6 amperes (step S2). If it is judged that the lamp voltage is higher than 25 in step S1, the control circuit 304 performs a constant current control with the current limiting level set to 4 amperes (step S3). When the lamp voltage rises and reaches 50 volts, the control circuit 304 performs a constant power control so that the lamp power remains to be 200W.

In an existing or new client/server system environment in which a plurality of clients are connected on a network, a function of specifying (selecting) a desired article by a requester, a function of requesting an approver to approve purchase of the specified article, and a function of determining approval or rejection for purchase of the approval-requested article by the approver are realized. A user logs in to this system as a requester or approver from a predetermined Web page displayed on the client in accordance with the user (employee) ID. A user who has logged in as an approver can also use the article specifying function and approval request function.
摘要:
In a powder charging apparatus according to the present invention, powder is delivered to a delivery tube using delivery air, and an external drive voltage is applied to a vibrator to vibrate the surface of the vibrator. The powder is dispersed around the vibrator when the powder passes through an enlarged diameter portion, and the powder is subjected to vibration from the surface of the vibrator. Thus, each powder particle passes through the enlarged diameter portion while repeatedly colliding against the surface of the vibrator and the inner wall surface of the enlarged diameter portion, which are electrification members. At this time, the surface of the vibrator and the inner wall surface of the enlarged diameter portion charge the powder particles by contact.

A cushioning material for packaging is formed of a foldable and regenerable sheet, such as a corrugated cardboard or thick paper, and is used to protect an article of a rectangular cross-sectional shape packaged in an outer case. First and third frame members (1a, 1c) for forming a pair of parallel edge members of a rectangular frame, and second and fourth frame members (1b, 1d) for forming the other pair of parallel edge members of the same frame are provided, and the frame members (1a-1d) are formed of hollow bodies having a plurality of hollow portions (10) arranged in parallel, the contour and sizes of cross sections intersecting the hollow portions (10) being substantially equal. The hollow bodies constituting the frame members (1a-1d) are formed in a row by folding corrugated cardboard, thick paper or other foldable sheet, adjacent frame members among frame members (1a-1d) being connected to outer side sheet portions (11) positioned on the outer side, when the frame members (1a-1d) are assembled into a rectangular frame, the end portions of adjacent frame members out of the frame members (1a-1d) having joint structures (16) for combining the frame members together at right angles to each other with the outer side sheet portions (11) left as they are. Therefore, this cushioning material for packaging is rarely deformed, and displays an excellent cushioning effect.

Disclosed is a gallium nitride-based compound semiconductor device, including a laminate film consisting of a plurality of layers stacked one upon the other to form a pn-junction and formed of InGaAlN. The semiconductor device also includes an n-side electrode and a p-side electrode to supply current to the pn-junction. Further included is a heat generation structure formed within the laminate film. The heat generation structure includes a low resistivity portion having a relatively low resistivity and a high resistivity portion having a relatively high resistivity and positioned adjacent to the low resistivity portion. The low resistivity portion and the high resistivity portion are formed within a single layer, differ from each other in carrier concentration, and formed by introducing an impurity into the single layer in a different dose such that the low resistivity portion is positioned closer to the p-side electrode than the high resistivity portion.
