Title: Guiding method of unmanned truck by magnetic paint
Inventor: SAITOU ATSUSHI
IPC: G05D1/02
Filed: 1983-03-10
Abstract: PURPOSE:To obtain durability and to realize an unmanned run free of deterioration in function by providing and magnetizing a guide line coated with magnetic paint on a running path surface, and running an unmanned running truck equipped with a magnetic force detector. CONSTITUTION:The running path surface 1 is coated with the paint 2 containing mixed magnetic powder. Then when a magnet 3 is put close onto a guide path 2 of magnetic powder made of the paint, the guide path 2 is magnetized permanently. When the magnet 3 is moved along the guide path 2 closely, the magnetic path is magnetized only in the range. Then, the truck is placed on the road surface 1 so that magnetic force detectors 6 and 7 loaded on the truck 5 are positioned on the left and right sides of the guide path, and consequently the left and right detectors 6 and 7 detect the magnetic field 8 produced by the guide path 2. Then, the truck 5 is run automatically along the guide path 2 by being controlled so that the detected magnetic forces of the left and right detectors are equalized to each other.

Abstract: PURPOSE:To reproduce a color with fidelity by controlling each element of a matrix based on a reference signal and an output value by a simulation output means and deciding a masking coefficient through multiple regression operation so as to minimize a color difference giving perception to persons. CONSTITUTION:Three-primary reflectance density signals R, G, B are converted by a density conversion means 32 and three-primary color main density signals DR, DG, DB are inputted to an arithmetic means 33. Then a masking coefficient control means 37 sets an initial value of a masking coefficient to the means 33. The masking operation is implemented with the means 33 by using the coefficient. A printer control signal is inputted to a simulation output means 35 via a gradation correction means 34 to acquire three stimulus values. Then the means 37 uses a specific equation to convert the three stimulus values into coordinates in a uniform color space. Furthermore, the three stimulus values by a colorimeter based on reference color chips are fed to the means 37 by a reference signal supply means 36 and the values are converted into coordinates in the uniform color space by the means 37, and a minimum color difference is stored in the means 37.

Title: Diaphragm device
Inventor: SAWAI YASUMASA
IPC: G03B9/07
Filed: 1992-02-26
Abstract: PURPOSE:To provide a compact diaphragm device with a small number of parts. CONSTITUTION:When the diaphragm is closed, the central part of a lens opening is shielded from light in a belt state (part T) by main diaphragm blades 12b and 13b provided with chamfers in a state where they are superposed with each other. Opening part S and part U on both sides which are not shielded are each shielded by auxiliary blades 12a and 13a. Although the four pieces of diaphragm blades are moved as the diaphragm is opened, the amount of movement of auxiliary diaphragm blades 12a and 13a is smaller than that of the main diaphragm blades 12b and 13b. In the state where the diaphragm is opened, the auxiliary diaphragm blades 12a and 13a are completely superposed with the main diaphragm blades 12b and 13b. With this constitution, the maximum size in the direction (x) at the time of opening is shortened in comparison to the conventional two pieces of diaphragm blades.

Abstract: PURPOSE:To convert input frequency information into an audible frequency by holding the information and, at the same time, to eliminate the influence of a temperature change, etc., so as to improve the detection accuracy of a sonar by storing input signals after converting the signals into digital signals and changing the reading-out speed of the stored signals. CONSTITUTION:Input signals are stored in a memory 4 after the signals are amplified 1, sample-held 2, and A/D-converted 3, and the reading/writing timing of the memory 4 is controlled by means of a memory controller 9. On the other hand, the signals are converted into DC pulse signals by means of a rectifier 7 after the signals are detected 6 and outputted to a comparator 8. The comparator 8 only extracts the signals at levels higher than a prescribed threshold so as to eliminate under-water noise and writes the extracted signals in the memory at the timing instructed from the controller 9. In order to lower the pulse period T of digital signals to the pulse period T' of an audible frequency, the digital signals are supplied to a D/A converter 5 by reading the signals at a clock which is, for example, 10PW slower than the pulse width PW of a write clock and converted into analog signals so as to use the analog signals as audible signals.

Abstract: PURPOSE:To eliminate a system down state and to improve the reliability of a system by providing two earth stations and sending a pilot signal when one station detects a signal break while the other sending a pilot signal. CONSTITUTION:When an opposite station sends the pilot signal, this station confirms that by the lamp illumination of a pilot signal receiver 3 and turns on an SW 1. The pilot signal is received right after that, so a reset signal is inputted to a timer 4, so a time-out state is not entered and no pilot signal is sent. If the pilot signal of the opposite station is ceased, the receiver 3 receives no pilot signal, no reset signal is inputted, and the timer 4 counts up the time. A time-out signal is outputted unless the pilot signal is received within the time-out time, the S-side input of an FF 5 is turned on, and the output is turned on, so that an SW 2 is turned on. Consequently, the pilot signal is sent through a synthesizer 2 connected to a pilot signal generator 7. The opposite station recovers from the abnormality during this period.
