Title: Handling apparatus with weighing function for very small part
Inventor: AMIMOTO TOSHIYUKI
IPC: G01G11/00
Filed: 1990-04-20
Abstract: PURPOSE:To measure the weight of a very small and light part during the transfer with high accuracy by providing a measuring means or measuring the weight of a holding means which holds the very small part via a point of application to which the weight of the holding means supported by a weighing member is loaded. CONSTITUTION:A holding means A holds a to-be-measured very small and light part by a finger 32. The holding means A is set at a predetermined state. When a motor 9 is driven, a motor 13, a reducing mechanism 14 and the means A are moved downward in a Z direction via a movable plate 10 along a vertical linear guide 8. As a result, a plate 21 of the means A comes in touch with a rod 37 of a weighing member 36, and the whole of the means A sways around a shaft 20. Accordingly, the member 36 supports and bears the weight of the means A. The weight freed onto the member 36 acts to a point of application 33a. The force impressed to a measuring means is calculated. Thereafter, the weight of the means A is calculated from the length of the center of the shaft 20 of the plate 21 to a contact point of the plate with the rod 37 and, the like. The weight of the to-be-measured part can be measured with good accuracy by subtracting the known weight of the means A from the measured weight.

IPC: G01R31/02
Filed: 1981-07-01
Abstract: PURPOSE:To detect partial discharge correctly by applying correlation processing to a partially-earthed discharge current via a band-pass filter and to a commercial supply signal whose pulse is transformed into a rectangular-wave pulse, and thereby preventing the intrusion of outside noises. CONSTITUTION:A secondary current in accordance with a magnetic field corresponding to the partial discharg caused by the insulation inferiority of a power cable is detected by a current transformer 3 and turned into a partial discharge signal freed from outside noises such as a commercial frequency and a radio freuency through the intermediary of BPF4. This signal and a commercial supply signal whose pulse is transformed into the rectanguar by a transformer 11' are subjected to correlation processing by a correlator 5. When the signal from BPF4 becomes large, the partial discharge is indicated and detected correctly by an abnormality indicator 6 without being affected by the outside noises, since the signal from the transformer 11' has a constant level.

Title: Cnc data correcting method
Inventor: KAMIGUCHI MASAO
IPC: G05B19/414
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for correcting NC data so as to precisely work a desired working shape. SOLUTION: Respective actual working positions P1, P2... corresponding to the command positions S1, S2, S3... of the respective blocks of NC data are obtained by trial work. Concerning the command positions S1, S2, S3... of the respective blocks, the point symmetrical positions of the respective corresponding actual working positions P1, P2... are obtained. Corrected NC data is generated by setting the point symmetrical positions to be the corrected command positions of the respective blocks. Corrected NC data is added with a correcting quantity correcting a positional error caused by the delay of a servo system. Thus, at the time of working by corrected NC data, this correcting quantity and following delay caused by the actual delay of the serve system are cancelled to obtain a more precise working shape.
