摘要:
The present invention relates to a speed change control apparatus for controlling the speed change of an engine without using a clutch. In this apparatus, a mechanical transmission comprising a plurality of gears and having a neutral position provided between a main motor for running and a driving wheel. Speed change of the engine is performed as follows. First, the rotation speeds of the driving wheel (namely, the drive shaft) and the main motor are detected. Then, the main motor is operated without load. When the motor starts an no-load operation, the gears of a transmission are disengaged. Thus, the transmission is shifted to the neutral position. Subsequently, the rotation speed of the main motor is controlled so that the gears are engaged when both the rotation speeds of the wheel and the motor are nearly synchronized with each other.

A cellular phone receives a position measurement result, which indicates a position of the cellular phone determined based on both GPS satellite information and CDMA base station information, from a location information server. Then, when a value indicated by uncertainty information of the position measurement result is greater than a first threshold value, the cellular phone receives another position measurement result, which indicates the position of the cellular phone determined based only on the CDMA base station information, from the location information server and displays it on a display device.

A variable valve timing mechanism changes a relative rotation phase of a camshaft to a target phase based on hydraulic pressure supplied to an advance and a retard sides pressure chambers. A lock mechanism is placed in a locked state in which the relative rotation phase is locked at a maximum retard phase when the hydraulic pressure in the advance and the retard side pressure chambers is low, and that is placed in an unlocked state in which the locked state is released when the hydraulic pressure becomes high. Hydraulic pressure regulations in a first mode that changes the relative rotation phase to a side toward the maximum retard phase and in a second mode that changes the relative rotation phase to a side away from the maximum retard phase are executed in combination during a period from when an operating switch is turned off until a crankshaft stops rotating.

A sound signal generator includes a sound signal output function for outputting a sound signal to a command-driven amplifier that drives a speaker by using the sound signal being converted according to a control command, a first counter control function for changing a content of a first counter in a storage medium in a predetermined manner, a control command sending function for sending a control command to the command-driven amplifier upon having change in the content of the first counter in the predetermined manner, and a second counter control function for changing a content of a second counter in the storage medium in the predetermined manner upon having the control command sent to the command-driven amplifier by the control command sending function.
摘要:
A method of polishing a semiconductor substrate surface having at least one ruthenium feature thereon and at least one dielectric material, wherein the substrate is contacted with an aqueous composition containing from about 0.0005 to about 1 moles/kilogram of periodic acid, from about 0.2% to about 6% % by weight of silica abrasive having an average particle size of about 50 nm or less, and an amine in an amount sufficient to adjust the pH of the composition to between about 2.5 and 7. The removal selectivity of the ruthenium to a. low-K dielectric is greater than 20:1. Advantageously, the substrate further has a tantalum-containing compound, and the polishing rate of the tantalum-containing compound is about the same as the polishing rate of the ruthenium, so that the polishing process is a one-step process.
摘要:
An onboard navigation apparatus provides travel guidance on a road including a plurality of roadways heading in the same direction. The road specifically includes a special roadway such as a carpool lane having no exits to other roads, an ordinary roadway having exits to the other roads and a predetermined traveling-path changing area provided as a sole area allowing a vehicle to change a traveling path thereof between the special roadway and the ordinary roadway. The apparatus determines a present position of a vehicle, determines whether the detected position is in the special roadway or in an ordinary roadway. The apparatus provides, in addition to normal travel guidance, information on the traveling-path changing area existing ahead of the vehicle on a display, when the detected position is in the special roadway.

A cellular phone unit receives GPS satellite information of GPS satellites and base station information of base stations. It extracts the GPS satellite information and the base station information that meet transmission conditions, which are provided by a location information server, out of the obtained GPS satellite information and base station information. Those extracted information are sent to the location information server. Based on the receiving from the location information server a transmission condition in terms of the condition of accurate specifying of the location of cellular phone unit by the location information server, the cellular phone unit can extract proper GPS satellite information and base station information and send the extracted information to the location information server.
