Title: Slow-travelling control device for vehicle
Inventor: NISHIDA MINORU
IPC: B60W10/06
Filed: 1990-04-06
Abstract: PURPOSE:To enable the stop-and-go driving which repeats stop and start in a delay travelling only with brake operation by controlling the engine output and a transmitting mechanism so as to start and travel at low speed with a slow-travelling mode when a brake is not operated. CONSTITUTION:When a driver turns a slow-travelling mode setting switch 10 on to input a desired target speed to a slow-travelling speed setting device 23, a display device 14 displays a change to the slow-travelling mode. In the case that the driver does not operate a brake, a driving force control device 20 is controlled with the command signal SC output on the basis of the control method with a program of a computer unit 2 independently from the existence of the operation of an acceleration pedal, and the speed of a vehicle is adjusted so as to coincide with a slow-travelling speed set value. On the other hand, the driver operates the brake pedal, the computer unit 2 outputs the driving force lowering signal to the driving force control device 20 on the basis of the signal SB from a brake switch 21.

Abstract: PURPOSE:To possibly minimize the initial clearance between a movable scroll member and a stationary scroll member which is exposed to open air by shaping the movable scroll member out of a material having lower coefficient of thermal expansion than that of the material of the stationary scroll member so as to make the thermal expansions of both the scroll members approach to each other. CONSTITUTION:A movable scroll member 9 is enclosed all around by a housing 5 and a stationary scroll member 11, however, the stationary scroll member 11 is exposed to open air throughout the external periphery thereof so that it cools the member 11. The stationary scroll member 11 and th movable scroll member 9 are shaped out of iron and carbon fiber reinforced aluminum having lower coefficient of thermal expansion than the iron, respectively. Since the movable scroll member 9 has lower coefficient of thermal expansion than that of the stationary scroll member 11, the thermal expansions of both the scroll members 9 and 11 approach to take substantially near values finally. The initial clearance may be minimized possibly but the contact of both the scroll members 9 and 11 be prevented.

Abstract: PURPOSE:To avoid erroneous detection of abnormal reflecting part other than a bright line in the detection of the configuration by an optical cutting method by scanning the image of the bright line from the upper part to the lower part and avoiding the detection of a bright spot below the bright line. CONSTITUTION:When the slit bright line 11 is formed by the irradiation of the light from the upper part on a soldered part 10, i.e. an object to be measured, the btight spot is generated at a positive reflecting point 12 by part of scattered light. When it is observed from the direction of a lens 8, the abnormal reflection is formed on the optical cutting image as disturbance. Said abnormal reflection part is present at the pat lower than the object surface to be meansured, i.e. the slit bright line. The bright line is detected by scanning it from the upper part to the lower part in a vertical direction in an image pickup device. The image signal is compared with a preset value on the scanning line. when the signal is larger than the preset value, it is judged as the optical cutting line. When the optical cutting line is detected at first on one scanning line and thereafter the bright spot is further detected, it is judged as the abnormal reflecting part but it is not judged as the optical cutting line.
