Abstract: PURPOSE:To perform correct addition and subtraction even if temperature fluctuates, by arranging a temperature compensating circuit on one signal processing circuit side of an adding and subtracting circuit. CONSTITUTION:An input signal (a) from a signal source 5 is applied to an input terminal 9 of the adding and subtracting circuit 4 through a signal processing circuit 2 with larger time lag.

Title: Conveyor tilting device
Inventor: KAJITANI TOSHIO
IPC: B65G21/14
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a conveyor tilting device to perform a simple, easy, and besides accurate regulation work. SOLUTION: A conveyor tilting device forms a split in parallel to the direction of a device shaft 3 throughout a range of the surface of the upper part 10 of a conveyor support block 8 to a cylinder hole 9. When a screw is screwed in a screw hole 12 for split clamp, an upper part 10 is elasticity deformed, the split width is narrowed, and the inner peripheral surface of the cylinder hole 9 of a conveyor support block 8 is brought into pressure contact with the outer peripheral surface of the bearing housing 6. Further, when the screw is fastened, the split width is widened, the inner peripheral surface of a cylinder hole 9 is separated from the outer peripheral surface of the bearing housing 6.  Thus, when a conveyor base 7 is tilted integrally with the conveyor belt 1, by unfastening the screw, frictional resistance between the inner peripheral surface of a cylinder hole 9 and the outer peripheral surface of the bearing housing 6 is decreased, whereby tilting is practicable by a weal force.

Abstract: PURPOSE:To extract a contour by simple algorithm and to speed up the operation by classifying density gradient vectors into two X- and Y-directional groups, comparing an image processed by a maximum filter with an original image, and ORing the two groups again. CONSTITUTION:A density gradient vector calculation part 2 receives image information from a picture element input part 1, calculates X-directional and Y-directional density gradient vectors in respective image addresses, and outputs the absolute values (FP) of density gradients in respective image addresses and the directions (GP) of the density gradient vectors.

Abstract: PURPOSE:To output the output waveform whose pulse width distortion is small without being influenced by the decrease of output of an amplifier by comparing amplifier outputs whose phases are opposite to each other, obtained by converting an optical signal to an electric signal. CONSTITUTION:A comparator 12 sets a reference voltage VR of a reference voltage source 11 as a threshold voltage, and outputs a pulse signal.

Accordingly, phases of optical signals outputted from the diodes 13, 14 are opposite to each other. Optical signals which are made incident through optical fiber cables 3, 4 are converted to electric signals by photodiodes 21, 22 of a light receiving part 2, and amplified by amplifiers 23, 24. A comparator 25 compares two amplifying signals and outputs a square pulse whose waveform is shaped as an output signal VO. In such a way, an output waveform whose pulse width distortion is small can be outputted without being influenced by an output fall of the amplifier in the case a frequency of an input pulse is higher than a cut-off frequency.

Title: Hydrodynamic engine mount
Inventor: MIYAMOTO YASUO
IPC: F16F13/00
Filed: 1983-02-18
Abstract: PURPOSE:To improve the vibro-isolating characteristic of secondary vibration in a hydrodynamic engine mount, by installing a passage to be interconnected to a fluid chamber in a base member additionally, while sealing a fluid inside the fluid chamber in the passage and loading a retractable weight inside. CONSTITUTION:A passage 13 is horizontally installed outward in a more upper part than a partition wall 15 of a cylindrical body 11 on a base member 10, while a large diametral passage 14 is continuously formed in an outer end part of this passage 13, and a weight 50 is slidably loaded inside the large diametral passage 14. When such a lower frequency vibration than that of resonance frequency in a resonant system comprising the fluid is inputted into a setting member 20, the resonant phase of the weight 50 advances one-sidedly whereby a pressure variation inside the fluid chamber 2 comes smaller. Therefore, vibration transmission to the base member 10 decreases so that the vibro-isolating characteristic of secondary vibration in a hydrodynamic engine mount 1 is thus improved.
