Title: Apparatus for measuring oil level
Inventor: SHIMIZU SHIGEO
IPC: G01F23/28
Filed: 1993-12-16
Abstract: PURPOSE:To provide a measuring apparatus capable of measuring an oil level of an oil level sensor of an axle box efficiently in a considerably short time while a vehicle is running. CONSTITUTION:This measuring apparatus is set at a position where an oil level sensor of an axle box of a running vehicle is photographed. The apparatus is provided with an image pick up device 1, a binarizing means and an oil level-detecting means. In the image pick up device 1, when a vehicle detector 3 detects the vehicle reaching the image pick up position, a strobe 2 projects light thereby to obtain a still image of the oil level sensor and outputs a signal of the image. Image data obtained by converting image signals from the image pick up device 1 to digital values are binarized according to a plurality of binarization levels to form a plurality of binary image data in the binarizing means. Meanwhile, the oil level-detecting means detects a position of the oil level sensor from the binary image data including the image of the oil level sensor, sets a longitudinal level check line in the oil level sensor, measures vertical coordinates where luminance data of pixels on the check line show a great change and detects the oil level.

Title: Automatic voltage regulator for generator
Inventor: YAMAGUCHI HIDEMI
IPC: H02P9/08
Filed: 1988-12-16
Abstract: PURPOSE:To suppress the overvoltage of a generator at the time of start by selecting one of a plurality of voltages settable by a voltage setter by a set voltage setter connected to the voltage setter, and outputting it to a comparator. CONSTITUTION:A voltage setter 3A outputs a voltage of 80, 100% of a set voltage from voltage output units 11, 12 as a target voltage. A set voltage switching unit 13 operated upon reception of a switching signal at the time of start of initiation of a generator selects the output of the voltage output unit 11, i.e., a target voltage of the 80%. This target voltage is input to a comparator 9, and even if a generator voltage is not obtained at the initial of the start, the generator raises its voltage toward the target voltage 80% upon reception of the output of low voltage of the comparator 9. Thus, a voltage overshoot is temporarily raised from a 80% line l2, but does not reach at least 100% line l2. Here, after a predetermined time, the set voltage switching unit 13 is switched by the switching signal to select the target voltage of the 100% of the output of the voltage output unit 12.
