In a vibration actuator using a magnetic circuit device (14), a supporting arrangement (23) elastically supports the magnetic circuit device. A coil (17) is inserted into a magnetic gap (15) of the magnetic circuit device and is supported by a vibration plate (19). The vibration actuator has a first operation mode in which the magnetic circuit device mainly vibrates to transmit vibration through the vibration plate to the outside, a second vibration mode in which the coil mainly vibrates to produce a buzzer sound through the vibration plate, and a third vibration mode in which the magnetic circuit device and the coil mainly vibrate to produce a sound corresponding to a speech through the vibration plate.

A transmission ratio control apparatus for a friction-wheel CVT requires no feedback of the offset of a friction wheel and performs stable transmission ratio control. A control circuit is provided for controlling the offsetting of the friction wheel to change transmission ratio. A first unit of the control circuit determines a target input rotational speed based on the throttle valve opening and the vehicle speed. A second unit determines target transmission ratio corresponding to the target input rotational speed. A third unit determines an rotational angle instructional value for a motor to achieve the target input rotational speed. A fourth unit determines a changing rate of actual transmission ratio based on the input rotational speed and the vehicle speed. A fifth unit corrects the motor rotational angle instructional value to reduce changes in transmission ratio as the transmission ratio changing rate increases, and outputs the corrected instructional value to the motor.

This invention provides a percutaneous absorption preparation for use in the percutaneous administration of drugs for percutaneous absorption into the living body for the purpose of preventing or treating various diseases, which has excellent adhesion to the skin and does not cause pain and damage to corneum when peeled off. Its pressure-sensitive adhesive layer contains an acrylic copolymer comprising a (meth)acrylic acid alkyl ester and a functional monomer as essential components, a fatty acid ester having a specified number of carbon atoms, a monoglyceride having a specified number of carbon atoms and a drug for percutaneous absorption, and the pressure-sensitive adhesive layer is crosslinked. Since its skin adhesive property is improved by the inclusion of the monoglyceride, release of the drug from the preparation is improved and the area of the preparation can be miniaturized.
摘要:
Sensors (20, 21) provide a degree of throttle valve opening (TVO) and an output shaft revolution speed (No) to CPU (10), respectively. CPU (10) carries out a fuzzy inference for each gear position based on two kinds of parameters referring to a driving force deviation (Ef(i)) and a fuel consumption ratio (Qf(i)), and selects a speed change ratio which makes the appraisals for the driving force deviation and the fuel consumption ratio best, as a mark speed change ratio for the next gear position (NextGp), according to a predetermined program. Thus the shift control system selects a gear position corresponding to the speed change ratio by which the deviation between the driver's requiring driving force and the driving force after shifting becomes few, while the fuel consumption ratio becomes good.
摘要:
A ratio control of a continuously variable transmission according to the present invention proposes governing which position a shift actuator is to take versus a throttle opening degree and a vehicle speed in accordance with a predetermined shift pattern predetermined for various combinations of the throttle opening degree and vehicle speed, and overriding this governing step to put the actuator in motion away from a maximum reduction ratio position when the vehicle speed has satisfied a predetermined relationship with a value that has been derived from a predetermined data at acceleration.
摘要:
In a closed type thermal power generation plant, the fuel is supplied in the combustor and burnt therein in the presence of oxygen, instead of air. The combustion gas mainly including water and carbon dioxide is delivered from the combustor into the turbine. A turbine exhaust gas is fed into the waste heat boiler to carry out heat exchanging operation therein and an exhaust gas mainly including water component and carbon dioxide from the waste heat boiler is fed into the condenser. The gas component mainly including the carbon dioxide is separated from the condensate in the water-gas separator and may be fed into the combustor in a compressed state, or the separated gas component may be recovered externally to the plant without emitting the same into the atmosphere. The separated condensate is fed into the waste heat boiler to be subjected to heat exchanging operation therein to generate superheated steam which is to be fed into the combustor, or may be recovered externally.Further, a steam turbine may be connected to the waste heat boiler and generator. A condensor may then be connected to the steam turbine and waste heat boiler so that the steam turbine, condenser and waste heat boiler constitute a closed cycle.

An adaptive control of a lock-up clutch is disclosed. An initial value of an operating signal on which an electric actuator for the lock-up clutch operates is modified based on a deviation of a lag or delay from a target timer interval such that the initial value is increased when the lag is longer than the target time interval, while it is decreased when the lag is shorter than the target time interval.
