Title: Cleaning system for magnetic head
Inventor: NANBA TATSUO
IPC: G11B5/41
Filed: 1979-10-17
Abstract: PURPOSE: To obtain higher effect of cleaning when the dust attached to the magnet- ic head is cleaned away, by rotating the head in the opposite direction to the rotation given for reproduction.  
     CONSTITUTION: When the rotary magnetic head 2 is cleaned, the current of opposite polarity to the normal case is applied to the rotor motor to secure the reverse rotation for the rotor 1. When the rotation of the rotor 1 reaches the stationary state, the rotary solenoid 5 is started. And then the rotatable cleaning brush 3 is pressed to the head 2 to clean the magnetic head. During the cleaning, the rotor 1 has the forward and backward rotations alternately to increase the cleaning effect. Also the rotor 1 can always be kept clean by performing the cleaning in the timing by which the action to take out the tape is started.

Abstract: PURPOSE:To obtain the liquid crystal display device which is improved in the reliability of the correction of a bright point picture element and removes limitations of the correction position. CONSTITUTION:When the bright point picture element 5 is detected, the periphery of the surface of a glass substrate 2, positioned on the incidence side of a liquid crystal panel 1, on the same irradiation path with the bright point picture element 5 is irradiated with a laser beam 10 from an excimer laser oscillator 9 to perform excimer laser etching, and consequently a recessed part 18 which has a rough bottom surface 19 is formed. Then a slit pattern mask is inserted into a slit pattern and only the center part of the recessed part 18 is irradiated with the laser beam 10 to form a center rough surface 17 which is deeper than the peripheral part in the center of the bottom surface of the recessed part 18. Consequently, light scattering effect can be made larger at the center part of the recessed part 18 than at the peripheral part.

Title: Running circular saw machine
Inventor: OKAJIMA HIROSHI
IPC: B27B5/18
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent a biting to blades by a cut surface from generating. SOLUTION: After a marking blade 36 precedes and cuts to an intermediate thickness of a laminated corrugated fiberboard, a main saw blade 37 cuts to the total thickness of the laminated corrugated fiberboard, and for this reason, a biting to the marking blade 36 and the main saw blade 37 by the cut surface is softened. Since the pressing force by a pressing mechanism for the laminated corrugated fiberboard is made 0.007 kg/cm<2> per corrugated fiberboard constituent layer, the laminated corrugated fiberboard is prevented from deforming, and in addition, the biting by the cut surface is prevented from generating.  Since the rotation circumferential speeds of the marking blade 36 and the main saw blade 37 are made 5-20 m/s, the incapability in cutting due to a too slow speed does not generate, and also, there is no fear for the generation of vibrations of the blades 36, 37, and the generation of the biting by the cut surface due to a too fast speed.

Title: Electronic variable impedance device
Inventor: KOMINAMI YASUO
IPC: H03G3/10
Filed: 1981-08-28
Abstract: PURPOSE:To prevent a high frequency signal from becoming abnormal right after a power source is put to work, by supplying the voltage of a bias circuit to a voltage current converter through a diode right after the power source is turned on. CONSTITUTION:A power voltage Vcc is applied to the base of a transistor (TR) Q11 of a bias circuit BC through a starting resistance R34, so the TRQ11 is turned on even right after the Vcc is applied. The Zener voltage of a Zener diode ZD is therefore divided through resistances R32 and R33 and then supplied to the anode of a diode D1, so TRs Q2 and Q15 of the voltage current converter 3 are turned off. Thus, the diode D1 is connected to turn on and off the TRs Q1 and Q2 completely respectively right after the application of the Vcc, and a conversion output current which responds to the AC input signal is obtained at collectors of the TRs Q1 and Q2. Therefore, abnormal oscillation of a high frequency signal right after the power is supplied is prevented.
