The present invention relates to: a process for producing a cyclic silane compound, which comprises subjecting a chained polysilane to pyrolysis in the presence of an oxide of a transition metal belonging to Group 8 or Group 11 of the periodic table; and a process for producing a cyclic carbosilane compound, which comprises subjecting a chained polysilane to pyrolysis in the presence of a simple substance of a metal selected from the group consisting of transition metal elements and elements belonging to Groups 12 to 15 of the periodic table or a compound thereof.
摘要:
An acceleration control system stores a target acceleration calculation equation acquired by transforming an equation that expresses that a product of the differentiation of the square power of the speed and the environmental factor αenv represents a sensed value ε of acceleration. A surrounding environment monitor device detects surrounding bodies present in the forward periphery of the vehicle, and an environmental factor calculation unit calculates the environmental factor αenv by using the detected positions of the surrounding bodies. A target acceleration setting unit successively sets target accelerations aref in compliance with the target acceleration calculation equation by using the environmental factor αenv. The acceleration is executed to match the driver's feeling.

A method and an apparatus for estimating behaviors of a vehicle are provided. At least two GPS antennas are located along a longitudinal axis of a vehicle so that speed vectors at the positions where the GPS antennas are located can be determined based on GPS signals received by the GPS antennas. The speed vectors are known to be estimated with high accuracy based on the GPS signals. The positions of the GPS antennas on the local coordinate system are estimated based on such highly accurate speed vectors, so that the estimated positions may also have high accuracy. Based on a line connecting these highly accurate positions of the GPS antennas, an inclination of the longitudinal axis of the vehicle is estimated. Use of the high-accuracy speed vectors enables high-accuracy estimation on the positions of the GPS antennas and the vehicle direction on the local coordinate system.

A storage battery or a secondary battery is capable of improving the utilization of an active material and obtaining a high energy density, using raw materials having costs substantially equal to those of a conventional lead storage battery especially as a negative-electrode plate of the secondary battery. The negative-electrode active material for the secondary battery is a kneaded mixture including: a raw active material having a metal and an oxide of the metal; and carbon in such an amount that the total absorption number thereof is at least 4.7 ml per mol of the raw active material, in which the kneaded mixture contains no sulfates or sulfates in an amount of 7×10−2 mol or smaller per mol of the raw active material. The negative-electrode active material has a specific volume of 2.2×10−1 to 5×10−1 ml/g with subjected to no formation. The carbon is acetylene black or furnace carbon.

摘要:
An electronic control unit (ECU) having multiple layers of distributed network control functionality is used to facilitate development of complicated vehicle control network system. That is, for example, three layers of distributed network control functionality are devised in the ECU. The three layers of functionality include a so-called application layer that provides a structurally functional framework of function reusability, extensibility and independence as well as an interface (I/F) for functional context, a so-called system infrastructure layer that uniformly manages system resources for an entire system development scheme based on a rule, and a so-called hardware abstraction layer that controls hardware system as an abstractive object including electrical property of devices such as ECUs, sensors and/or actuators as well as a network itself.

The compositions according to this invention may also contain pharmaceutically or cosmically acceptable additives.
摘要:
A radio communication system between a mobile terminal station of a vehicle and a plurality of roadside fixed base stations is so constructed that communication areas of the base stations do not overlap with each other and satisfy the following two conditions. Condition (i): each communication area is defined so that there cannot be a plurality of terminal stations simultaneously. Condition (ii): it is needless to perform multiple access such as time division in the communication area and capable of affording the whole band and all the communication time allocated to one communication area to one terminal station and broad band communication becomes possible. Thus, each mobile terminal station can utilize all the frequency band allocated for service.
