摘要:
An electronic transmission control system for an automotive vehicle with a belt-type continuously variable automatic transmission comprises a transmission ratio control device including a first motor-driven oil pump supplying working pressure directly to a secondary pulley actuation chamber, and a second motor-driven oil pump supplying working pressure directly to a primary pulley actuation chamber and enabling working oil to come and go between the primary and secondary pulley actuation chambers therethrough. A first control section is provided for controlling the first motor-driven oil pump so that the actual secondary pulley pressure is adjusted to a target working pressure needed to hold a belt capacity of a drive belt, which belt capacity is defined as a capacity required for exerting a grip of the drive belt on primary and secondary pulleys. Also provided is a second control section which controls the second motor-driven oil pump by limiting a speed-change flow rate (or a speed-change velocity), so that the actual primary pulley pressure is prevented from reducing to below a lowest working pressure capable of holding the belt capacity.

An electronic transmission control system for an automotive vehicle with a belt-type continuously variable automatic transmission comprises a transmission ratio control device including a first motor-driven oil pump supplying working pressure directly to a secondary pulley actuation chamber, and a second motor-driven oil pump supplying working pressure directly to a primary pulley actuation chamber and enabling working oil to come and go between the primary and secondary pulley actuation chambers therethrough. A first control section is provided for controlling the first motor-driven oil pump with feed-forward compensation for the working pressure supplied to the secondary pulley actuation chamber, based on changes in a flow rate of the working oil coming and going between the primary and secondary pulley actuation chambers, so that the secondary pulley pressure is regulated as a belt capacity holding pressure needed to hold a belt capacity of the drive belt in a first motor-driven pump side. Also provided is a second control section controlling the second motor-driven oil pump, so that the primary pulley pressure is regulated as a belt capacity holding pressure needed to hold a belt capacity of the drive belt in a second motor-driven pump side and so that a required value of a speed-change flow rate of the working oil coming and going between the primary and secondary pulley actuation chambers is obtained.

The present invention provides a high pressure discharge lamp with a start-up assist member, a lamp unit, and a lamp system that reduce breakdown voltage and provide high design flexibility by reducing restriction on a position of an adjacent conductor. In a high pressure discharge lamp (10) of a lamp unit (1), a dielectric member (20) is on the outer surface of a first sealing part (101a). The dielectric member (20) made of a titanium compound has relative permittivity higher than that of fused quartz. An upstream end of a metal wire (21) is connected to an external lead wire (102b) projecting from a second sealing part (101b). A downstream end (21A) is in contact with the dielectric member (20). Upon lighting of the lamp, a corona discharge occurs at the point where the end (21a) is in contact with the dielectric member (20) so that breakdown voltage is reduced.

A gas diffusion electrode material of the present invention includes: a porous body (1) formed of continuous and discontinuous polytetrafluoroethylene microfibers (2) and having three-dimensionally continuous micropores (4); and a conductive material (3) supported on the porous body (1). Moreover, a density of the polytetrafluoroethylene microfiber (2) is lower in a surface region (1A) of a cross section of the porous body (1) than in an intermediate region (1B) of the cross section. In accordance with the present invention, the polytetrafluoroethylene having the predetermined three-dimensional structure is used, and so on. Therefore, it is possible to provide a gas diffusion electrode material excellent in power generation characteristics and durability.

There is provided a wireless communication apparatus for conducting communication between a high-order apparatus and a low-order apparatus, including a beacon reception unit and a beacon transmission unit. The beacon reception unit receives a first regular beacon signal (351) transmitted from the high-order apparatus. The beacon transmission unit transmits a second regular beacon signal (351) synchronizing a clock of the low-order apparatus to the low-order apparatus in a case where the beacon reception unit receives the first regular beacon signal (351). The beacon transmission unit transmits a temporary beacon signal (352) indicating that the clock of a local station is not able to be synchronized with a clock of the high-order apparatus, to the low-order apparatus, in a case where the beacon reception unit is not able to receive the first regular beacon signal (351).

A resist pattern slimming treatment method includes: a slimming treatment step of performing a slimming treatment on a resist pattern by applying a solution containing an acid onto a substrate having the resist pattern formed thereon, then performing a heat treatment, and then performing a developing treatment. A database storing kinds of resist material for the resist pattern, concentrations of acid contained in a solution to be applied onto the substrate having the resist pattern formed thereon, and line widths of the resist pattern corresponding to the kinds of resist material and the concentrations of acid is prepared in advance. The concentration of the acid contained in the solution used in the slimming treatment step is based on a concentration of the acid obtained from the database, using, as search keys, the kind of resist material and a target value of the line width of the resist pattern.

In sintering a metal powder after pressure molding into a given configuration, random amorphous flaky metal fine powders (10) are used as metal powder materials. In addition, spherical particulate metal powders 11 are used as main materials, and random amorphous flaky metal fine powders 10 having finer particle size than the metal powders 11 and produced by fracturing a metal fracture material by means of high-velocity gas swirling flow are used as sub-materials, and molding and sintering are performed in a state of dispersing the sub-materials (10) in the main materials (11). Thus, despite being a power metallurgical product, it is possible to obtain a metal product having a dense metallographic structure and excellent in properties such as mechanical strength.
