摘要:
The invention relates to an electric motor driven vehicle having a driving unit assembled with a motor and transmission mechanism. In order to avoid a load in a low rotational state of the motor, the transmission mechanism is connected with the motor and driving wheel within a range of predetermined rotational numbers in which the motor approaches the vicinity of maximum efficiency. Accordingly, motor driving is possible from the start, and because of the small electric power and the low heat generating quantity, cruising distance is extended and the apparatus is consequently made to be compact and of light weight. The transmission is provided with an automatic starting clutch and an automatic transmission is used as the automatic transmission, operation of the motor near the vicinity of maximum efficiency can always be maintained in the usual speed change range. The driving unit can be constructed compactly as a power unit of swing type. Further, an advantageous cooling mechanism of the motor and a wiring structure of an electric power supply cord are disclosed herein.

A braking control apparatus for use in a motor vehicle having at least one wheel comprising a master cylinder for generating a hydraulic pressure in response to a braking operation of a vehicle driver, an accumulator for accumulating a hydraulic pressure and at least one wheel braking cylinder for braking the wheel in accordance with a hydraulic pressure supplied thereinto. A passage system is provided so that the wheel braking cylinder is communicated therethrough with the master cylinder and the accumulator. In the passage system are provided first and second change-over valves for cutting off the pressure from the master cylinder, cutting off the pressure from the accumulator and a third control valve disposed between the wheel braking cylinder and the master cylinder or the accumulator for establishing and cutting off the communication therebetween. An control unit controls the operations of the first to third valves so as to, in response to cutting off the communication with the accumulator, establish the communication with the wheel braking cylinder, and then establish the communication with the master cylinder. This valve control prevents the high-pressure remaining in the passage system after the cutting-off of the communication with the accumulator from being rapidly applied to the master cylinder.

An article comprising a first portion which is formed porously by sintering of an alloy or cermet material and a second portion which is formed of a metal and intimately bonds to the first portion. For example, the article is a rocker arm for an automotive internal combustion engine, in which first portion is the wear-resistant tip portion and the second portion the body portion. The second portion is formed by molten metal forging, with the sintered first portion set in the mould as an insert, such that the molten metal under pressure is forced to infiltrate into the pores of the sintered first portion at least in a region contiguous to the interface between the first and second portions. This article features very high strength of the bond at the interface between the first and second portions.

A read image processing apparatus is provided for processing a read image read by line image sensors arranged such that one end parts of which adjacent to each other are overlapped in a sub-scanning direction. The read image processing apparatus includes a density variation detector, a seam processor, and a line image generator. The density variation detector detects whether a density variation occurs for not less than a predetermined number of times or not in each of a plurality of regions in a seam-read image. The seam processor generates a seam image by synthesizing the seam-read images read by the line image sensors adjacent to each other in accordance with a detection result made by the density variation detector. The line image generator generates a read image corresponding to one line based on read images read by the line image sensors and the seam image generated by the seam processor.
摘要:
The invention is related to a system and a method to determine whether a target equipment deviates from a normal state. If it is determined that the target equipment to be diagnosed deviates from the normal state, the degree of deviation of each parameter from the normal state as the reference is calculated as an abnormal contribution ratio. A failure cause is estimated from a similarity ratio between the calculated abnormal contribution ratio and the abnormal contribution ratio of each of the failure causes collected in the past and including failure phenomena and failure parts.
