IPC: G01H17/00
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To monitor vibrations which occur in products in the process of transfer and have possibility of impairing mechanical soundness with high reliability by detecting mechanical vibration as electric vibration and performing the frequency analysis of the vibration waveforms. SOLUTION: This vibration monitoring device is provided with a vibration detecting means 1, a frequency analyzing means 2, a damage evaluating means 3, etc. The means 1 is an element of a piezoelectric acceleration sensor, etc., converts vibration acceleration which is applied to a sensor that is individually bound to a conveying means, etc., on which components and products are loaded in the process of transferring the products into an electric signal and outputs it. The means 2 is an electric circuit which calculates the intensity of vibration waveforms which are detected with the means 1 in a certain fixed time in each frequency component and outputs a parameter that is necessary for damage evaluation in the next damage evaluating means 3. For a frequency analysis, e.g. fast Fourier transform is used.  Data after the fast Fourier transforms is represented in the form of a power spectrum density to a frequency.

Title: Laser condenser in laser working machine
Inventor: OGAWA YUKIO
IPC: B23K26/14
Filed: 1982-09-07
Abstract: PURPOSE:To make a titled device light in weight and small in size and to eliminate the need for manual focusing by utilizing the pressure of an assist gas in maintaining automatically the focal position of laser light in a specified position with respect to the work. CONSTITUTION:When the pressure Pc indicated by a pressure gauge 6 between a flow rate control valve 4 and a nozzle 5 in a laser condenser is set at a certain value, the distance l between the tip of a nozzle cylinder 10 and the work is made automatically constant. Therefore if the pressure Pc is controlled by the valve 4, the cylinder 10 slides vertically with respect to an optical waveguide cylinder 10. Since the cylinder 10 is supported on a cylinder 7 by means of a balancing spring 13, the desired distance l can be set by moving upward or downward the cylinder 10 in its axial direction. If the surface of the work is rugged, the cylinder 10 maintains the distance l constant by moving upward or downward by following up to the ruggedness during working and therefore the focal position of a condenser lens 12 is maintained always in the specified position with respect to the top surface of the work.

Title: Synchronization detection circuit
Inventor: ASHIZAWA TETSUO
IPC: G11B20/18
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To enable a frame position within a sector to be detected even when a synchronous signal is not detected, by setting a decoder for monitoring the synchronous signal of a plurality of frames and detecting each frame position from a relationship of a plurality of synchronous signals. SOLUTION: A synchronization-protecting circuit 12 carries out a synchronization detection and a protection operation to a common pattern part of synchronous signals of frames. Meanwhile, a decoder 21 receiving individual pattern parts of the synchronous signals of frames from a register part 13 decodes to which of 26 frames in a sector it corresponds from a relationship of the individual pattern parts of three frames. When the frames are provided in a regulated order, the decoded frame numbers are set in a pointer circuit 22. On the other hand, an output of a counter 23 receiving a count up signal is compared with a predetermined value M of a register 24. When the output is not smaller than the value M, the pointer of the pointer circuit 22 is compared with a value of the decoder 21 at a comparison circuit 26.

Title: Press
Inventor: TSUTSUI YOSHIMITSU
IPC: B30B15/04
Filed: 1983-08-29
Abstract: PURPOSE:To provide a press having improved working accuarcy by providing independently an inside frame to a main frame and providing respectively a working heat part and a slide guide to separate frames so that the slide guide is not affected by the deformation of the main frame occuring in the repulsive force of the slide. CONSTITUTION:When a crank shaft 9 is eccentrically revolved by a motor 7, a connecting rod 11 moves vertically back and forth thereby giving vertical movement via an intermediate rod 15 to a slide 19. The vertical movement of the slide 19 is accomplished in this stage by guide posts 21 guided by guide holes 33. Therefore even if working reaction acts on the slide 19, the working head part 5 of a main frame 1 receives the reaction and an inside frame 27 is prevented from receiving said reaction. A slide guide grame 29 is thus maintained always parallel with a bolster 3. As a result, the bottom surface of the slide 19 which is guided by the holes 33 of the frame 29 is also maintained parallel with the top surface of the bolster 3.

Abstract: PURPOSE:To prevent the damage of the stylus tip and a record and to ensure the reproduction with high fidelity, by detecting optically with no contact the size of the record to designate automatically the speed of revolution, and to regulate manually the speed when it is wrong. CONSTITUTION:A turntable 21 contains light refractors 13-15 set radially in three directions, and these refractors are covered with a rubber sheet 16. The beams of light emitting elements 25-25'' on a base 1 are refracted 24 and then refracted 13-15 again to be led to photodetecting elements 115-117. Then the presence or absence of a record as well as the size of the record are detected from the outputs of the elements 115-117. When a record is put on the table 21 and turned, the size of the record is detected. A motor 23 continues its revolutions at a high speed corresponding to the size of the record. The speed of revolution can be changed by pushing a control knob (not shown in the diagram) in case the speed is wrong or changed. In such way, the damage is prevented for the reproducing stylus and the record to ensure the reproduction with high fidelity.
