Abstract: PROBLEM TO BE SOLVED: To provide a low noise high frequency clock oscillator using a low speed voltage controlled oscillator. SOLUTION: This oscillator 20 includes 2m-sets of differential delay elements 28 connected in series in an inverting way (m is an integer larger than 0). In this case, an input signal pair to msets of 2-input exclusive NOR gates 30 is applied from a noninverting input terminal of each adjacent delay element 28. The oscillator 20 also includes an m-input OR gate which is connected to m-sets of outputs of the m-sets of the exclusive NOR gates 30 to generate the output signal of the oscillator 20. The delay elements 28 have a variable delay function controlled by a delay control signal(DCS). When the delay in each delay element 28 is changed, the frequency of the output signal of a clock oscillator is changed. The output frequency is equal to 1/2d (d is a delay time of each delay element 28).

Filed: 1989-07-31
Abstract: PURPOSE:To prevent the degradation of cross talk property by forming a narrow width part so as to cross a recording and reproducing gap and forming the shape of a rear end part in side rails, which sandwich the narrow width part, so as not be parallel with the recording and reproducing gap. CONSTITUTION:A narrow width part 5 is formed to cross a recording and reproducing gap 4 and to be coincident with track width Tw. Then, both ends 6 in the rear end parts of side rails 6, which sandwich the narrow width part, are formed at a certain angle to the recording and reproducing gap and a coil 3 is wound around a magnetic substance core 2. Accordingly, for signals to be reproduced in the both ends of the rear end parts in the side rails, phases are made different in the respective parts of the both ends. As a result, as the whole both ends of the rear end parts in the side rails, the reproduced signals are canceled each other and as a result, only a magnetic flux to be generated from a recording track, where the narrow width part crosses, can be reproduced. Thus, the degradation of the cross talk property can be prevented.

Title: Vibration gyro and inspecting device therefor
Inventor: OGAWA KENJI
IPC: G01C19/56
Filed: 1994-08-24
Abstract: PURPOSE: To improve the signal-noise ratio of a current component due to angular velocity by adding and feeding back the output of a current-voltage transformer, and lowering the gain of the current component attributted to the drive of a vibrator. CONSTITUTION: An adder 14 adds voltage VL and VR with resistors 142 to 144, upon receipt thereof from current-voltage transformers 4 and 5, and the voltage is amplified through resistors 145 and 146, thereby feeding a signal Vf back to converters 4 and 5. Also, a differential amplifier 14 outputs voltage VD corresponding to a difference between currents IL and IR (or difference between VL and VR) flowing across the piezoelectric section of a vibrator. In this case, the components of the currents IL and IR along a detection shaft or current components due to angular velocity are opposite-phase components and, therefore, the gain of a current component through the converters 4 and 5 becomes free from the effect of the signal Vf . On the other hand, the components of the currents IL and IR along a drive shaft or current components due to the drive of the vibrator have the same phase.  The gain of the current component through the converters 4 and 5 is, therefore, reduced, due to the feedback of the signal Vf . As a result, the signal-noise ratio of a current component due to angular velocity can be improved.

Title: Tube hose type wiper for rolling
Inventor: SATO TOSHIHIKO
IPC: B21B45/02
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To reduce required driving power by arranging the tube hoses to be mounted at wipers to an approximately V shape and directing their front ends toward the direction where a rolled stock advances to the wipers, thereby facilitating the attach ment and detachment of the hoses and the removal of the rolling mill lubricants and foreign matter on the surface of the rolled stock and using the friction force between the travelling rolled stock and the hoses for wiping. SOLUTION: Adequate rolling force is held between the material 2 to be rolled and the hoses 8 by hydraulic means prior to the start of rolling. When the rolling is started in this state, the hoses 8 are arranged to incline with stationary brackets 7 and, therefore, the working force on the hoses 8 are divided to the components of force in both edge directions from the axial center of the material 2 to be rolled, which components of force act to forcibly expel the rolling mill lubricants and foreign matter on the surface of the material 2 to be rolled. Further, the foreign matter is introduced by the hoses 8 and at the time of the movement of the parting between the material 2 to be rolled and the hoses 8 in the edge direction, the rolling mill lubricants act as a lubricant to facilitate the movement. The V-shaped hoses 8 may be either a division type or integral type.

Title: Automatic focusing device
Inventor: SUGI YASUYUKI
IPC: G03B13/36
Filed: 1988-08-12
Abstract: PURPOSE:To lengthen a base line length even if the dimension determining the lateral width of the automatic focusing device is reduced and to improve automatic focusing accuracy by deviating the external diameter center lens optical axis of at least one of a projection lens and a light-receiving lens. CONSTITUTION:An object 35 is irradiated with infrared light emitted by a light emitting element 32 through the projection lens 31 and its reflected light is converged by the light-receiving lens 33 to reach a light receiving element 34 through a parallel flat plate 36. Thus, the center of the lens external diameter is made eccentric with the optical axis of the lens. Consequently, the base line length l4 can be made long by a distance (r6-r7)/2+(r5-r4)/2, comparing it with an ordinary device whose optical axis is arranged coaxially so the automatic focusing accuracy can be improved.

Filed: 1993-07-19
Abstract: PURPOSE:To automatically take out residual rice and to automatically return and reprocess the taken-out residual rice by automatically closing a shutter when a sensor detects that grain is absent in a feed tank. CONSTITUTION:When grain is supplied to a feed tank 15 by an elevator 19 for charge and stored at a fixed quantity, a shutter 16 is opened. The opening/ closing degree of a resistance valve 32 is controlled by a resistance control motor 33 while observing the state of grain discharged from a finish rice milling chamber 9. Grain is returned to the feed tank 15 by an elevator 23 for finish and circulation until rice milling is made complete. When rice milling has been made complete, a changeover valve 26 is changed over. When a presence detection sensor 30 detects that grain is absent in the feed tank 15 in the next stage, the shutter 16 is automatically closed and the resistance valve 32 is automatically opened by the resistance control motor 33 of discharge residual rice. The residual rice is returned to the feed tank 15 by changing over the changeover valve 26 in the direction for which the residual rice is automatically returned.

Title: Flow control valve of fuel to gas burner and adjusting method thereof
Inventor: TOTSUDO RESURII KINGU
IPC: F16K31/06
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To lower the price of a cooking appliance for domestic use. SOLUTION: The flow rate of a gaseous fuel to a burner having an electrically operated electromagnetically actuated modulating valve 14 is remotely controlled. A poppet 76 for closing the valve is provided inside the modulating valve, current runs to an electromagnetic actuator with a coil 84 and a permanent magnet 96, and the poppet 76 is moved to open the valve. When the poppet 76 is fully opened, a metering member 80 mounted on a valve member 78 works to throttle the flow rate of a gas in proportion to increase in the current flowing through the coil 84 and the movement of the valve member 78. The electromagnetic actuator regulates the flow rate in a substantially linear relationship to the current flowing through the coil. Hence, the valve proportionally adjusts the flow rate of the gas according to a user's input from a controller of a type of a simple potentiometer.  The metering member 80 is cylindrical and equipped with a varying area groove or recess.
