IPC: G01R15/24
Filed: 1981-02-26
Abstract: PURPOSE:To realize the electric detection of a voltage of DC or low frequency approximate to the DC, by mixing the DC and the AC in a certain ratio for the base light and holding a certain amplitude of the modulated light given from a BSO sensor. CONSTITUTION:The outputs of an AC reference voltage source 201 and a DC reference voltage source 202 are synthesized by a synthesizer 203 and in a certain ratio, and the synthesized output is applied to an NFB loop 256 through an AGC205. The output of a light emitting diode E/O207 which is driven by a driving circuit 206 is partially extracted by an optical branching device 208 and reproduced into the electric signal through an O/E209 to be compared with the original electric signal by an adder 210. Thus the error is compensated. Then an output light 211 is fed to a reading part as an input light 212 and compared with the output of the source 201 by an adder 217 via an O/E213 and an AC component extracting circuit 215. And the AGC205 is controlled by the result of comparison.

Title: Moving object tracking apparatus
Inventor: KUZUTANI KEIJI
IPC: G01C21/00
Filed: 1989-02-08
Abstract: PURPOSE:To enable accurate tracking by arranging a processing means, a rotation sensor and a memory means to utilize a difference between running distances of a pair of wheels. CONSTITUTION:This apparatus is provided with rotation sensors 2 and 3, a memory means 7 and a processing means 1 to correct first and second conversion coefficients based on running distances of first and second wheels R and L while a change in azimuth indicated by a position corrected is below a specified value. As running distances of the wheels R and L are equal actually in a linear movement, errors are regarded as occurring evenly to set a correction value based on a ratio between a total of differences between running distances of the wheels and L and a total of revolutions of the wheels R and L. Then, conversion coefficients are corrected by addition of the correction value thereto or subtraction of the correction value therefrom. This simplifies a correction processing thereby eliminating errors more simply.

Title: Die cast sleeve
Inventor: FUKANO KATSUTOSHI
IPC: B22D17/20
Filed: 1989-02-10
Abstract: PURPOSE:To prevent the failure and nonuniform deformation of the inside surface of the sleeve in spite of the repetitive thermal load of molten metal injecting and cooling by forming three layers specifically into an integral structure, dividing the 2nd layer to a plurality in the axial direction and providing clearances in the axial direction. CONSTITUTION:The coefft. of thermal expansion of the metal of the 2nd layer 1b is larger than the coefft. of thermal expansion of the ceramics of the 1st layer 1a and the metal of the 3rd layer 1c and, therefore, even if the molten metal of a high temp. is injected into the die cast sleeve 1, the generation of the clearance 1x by a difference in the thermal expansion between the 2nd layer and the 1st layer 1a or the 3rd layer 1c is suppressed. The 2nd layer 1b which has the largest thermal expansion during hot is divided to a plurality in the axial direction and the divided layers are so arranged as to form the clearances 1x in the axial direction. Since there are the margins for deformation in the axial direction, the undue deformation by the thermal stress in the axial direction is prevented. The 1st layer 1a and the 2nd layer 1b adhered tightly to each other at the high-temp. time of molten metal injection and, therefore, the nonuniform deformation, such as camber and bend, of the ceramics of the 1st layer 1a is prevented as far as possible even if the die cast sleeve is assembled by the small margins for shrinkage fitting at the time of the assembly. The galling by the failure and nonuniform deformation of the ceramics is thus averted.
