Abstract: PROBLEM TO BE SOLVED: To obtain an optical information recording and reproducing apparatus by which the position of a light spot can be discriminated simply and surely by installing a means by which a tracking signal is fetched when the light spot is situated on a target lans or group on the basis of the judgment result of a judgment means. SOLUTION: A microprocessor (μP) 108 controls the speed of an optical head 102, and it sets the number of times (m) of the fetched loop processing operation of a tracking signal at m+1. the μP 108 calculates the target value X of a lens position servo signal, it judges the polarity Y of the value X, and it outputs the value X. At the time, phase computing processing operation and a gain multiplication processing operation are performed on the basis of the difference between the value X and a lens position sensor 105 obtained from an A/D converter 111. An obtained result is input to a tracking driver 114, and an object lens 103 is controlled to the position of the target value X. The μP 108 judges whether a target track is a land or a group, it judges the polarity of a tracking error signal, it repeats a processing operation, and it fetches a tracking servo signal.

Title: Rice washing device
Inventor: HASE KIHACHIRO
IPC: B02B1/04
Filed: 1994-06-06
Abstract: PURPOSE:To facilitate positioning of a valve to prevent the seizure of a motor by detachably attaching a valve, which opens and closes the discharge outlet of a rice washing tank, to a shaft which is able to go and back, and by attaching a regulator, which regulates the attaching position of the valve, to the shaft. CONSTITUTION:A regulator 5 is attached to the screw portion of a shaft 33, then a valve 3 is inserted into a shaft 4. A wing nut 34 is rotated along the screw portion 33 to push the valve 3 to the regulator to fix. A shaft 4 is raised to a position where the valve 3 is tightly fitted to a discharge outlet 2. If the valve 3 is tightly fitted to the discharge outlet 2 without being touched to the regulator 5, the regulator 5 should be lowered to a position where the regulator 5 is touched to the top surface of the valve 3. Therefore, the position of the regulator 5 is once determined, when the valve 3 is to be attached to the shaft 4 after the valve has been removed, the positioning of the valve can easily be performed by only rotating the wing nut 34 until the valve 3 is attached to the regulator 5.

Filed: 1995-05-23
Abstract: PURPOSE: To obtain exposure well balanced as a whole even in the presence of an object having high luminance by limiting an output level of an amplifier circuit controlling an aperture based on an image signal to be a desired value. CONSTITUTION: An image signal from a television camera is given to a terminal 1, and the signal is outputted to an output terminal 13 as an inverted amplification signal Vac via an inverting input terminal 11 of an operational amplifier A1. The inverted amplification signal Vac drives a drive coil 6 of a servo meter M via an operational amplifier A2 and Darlington transistors (TR2 , TR3 ). When an object is bright, the servo meter M drives the aperture in its closing direction and the gain for the case is set by a variable resistor VR1. A limiter circuit comprising a diode D2 and a variable resistor VR2 is provided in parallel with the variable resistor VR1 to limit an amplitude of the inverted amplification signal Vac due to the presence of the object having high luminance.  Collapse of parts of the image other than the high luminance part due to excess aperture closing of the high luminance part of the image is prevented.

Thus further with a displacement of trolley wires 21, 22 and a turning of the supporting beam 31 additionally performed, the before said current collector 24, 25 is displaced upward to locate the current collector to sideward of a truck frame 10a. In this way, by turning sideward in a manner likely to retract the current collector 24, 25, a tunnel floor 39 is raised to a level fully below the truck frame 10a, to widely reduce a height from the tunnel floor 39 to the truck, thus the tunnel cross sectional area can be reduced in the direction of height.

Abstract: PURPOSE:To make it possible to measure the moving speed of a matter, by receiving scattered beam obtained by irradiating the moving matter to be measured with laser beam through parallelly arranged limited openings by a photoelectric converter element while removing a DC component to detect zero crossing. CONSTITUTION:Laser beam is outputted from a semiconductor laser beam source 10 to irradiate a matter 17 to be measured while generated scattered beam is received by photodiodes 19a-19e through limited openings 18a-18e to receive space integration. A noise component is removed by this space integration and the obtained signal is imparted, for example, to the input terminal 21a of a signal processing part 18. Signals having different wave forms but same modes are inputted to the other input terminals 21b-21e. Thereafter, a DC component is cut by a DC component removing circuit 27a to obtain signals each having a zero crossing point. These signals are applied to a Schmitt circuit and pulse signals outputted from monostable multiplier come to pulse signals corresponding to zero crossings. These signals are inputted to a counter to perform measurement. The sum total of the numbers of zero crossings is correlated to the speed of the moving matter to be measured and converted to a speed amount signal by a speed amount converting circuit 24 to be outputted from an output terminal 25.
