Title: Head assembly and disk device
Inventor: WATANABE TORU
IPC: G11B21/21
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To enhance the bending stiffness and torsion stiffness of a load beam rigid body part by providing a slider-mounting part that is raised from a fixed part by a specific height and bringing a pivot being fixed to the tip part of a load beam into contact with the reverse side of the slider-mounting part. SOLUTION: A gimbal 50 is formed in one piece with a load beam 46, and a U-shaped slit 48 that is formed at the tip of the load beam 46 demarcates the gimbal 50. The load beam 46 includes a spring part 46a and a rigid body part 46b for pressing a head slider 26 to a disk, and a reinforcing plate 44 is joined to the reverse side of the rigid body part 46b by spot welding or the like. The reinforcing plate 44 is formed by stainless steel or the like and the thickness is approximately 1.0-2.0 times larger than that of the load beam 46. When the thickness of the reinforcing plate 44 is within this range, the resonance frequency of a head assembly 24B can be increased, thus minimizing the increase in mass.

Title: Semiconductor integrated circuit
Inventor: KAMEYAMA ATSUSHI
IPC: H01L21/82
Filed: 1990-09-28
Abstract: PURPOSE:To decrease the level fluctuation of a reference potential line without decreasing the degree of circuit integration, to prevent the malfunction of the circuit and to improve the reliability by providing a short-circuit means short- circuiting selectively the reference potential line, a high potential line or low potential integrated circuit. CONSTITUTION:The integrated circuit is provided with a potential control N- channel MOS transistor (TR) 23 and a differential amplifier 27. When the potential of a ground line 17 in a circuit block 13d is higher than the potential of a reference point 25 and exceeds a prescribed value, the output voltage of the differential amplifier circuit 27 exceeds a threshold voltage of the TR 23, which is turned on. Thus, since a current flows from the ground line 17 to a source potential line 21, the potential of the ground line 17 in the circuit block 13d is dropped. Thus, a difference between the potential of the ground line 17 and the potential at the reference point 25 is decreased and the potential fluctuation is decreased, then malfunction of the circuit is prevented. Thus, the stable circuit operation is realized even in the integrated circuit with less noise margin and the reliability is improved.

Abstract: PURPOSE:To comparatively easily execute the highly accurate position adjustment of laser beams by constituting a collimeter optical system of two lens members and allowing a 2nd lens member having a larger focal distance to be moved. CONSTITUTION:The collimeter optical system is constituted of a 1st lens member 3 arranged on the side of a laser light source and the 2nd lens member 4 arranged on the side of a convergent optical element 5, the absolute value of the focal distance of the member 4 is larger than that of the member 3 and the member 4 can be adjusted at its position independently of the member 3. Namely, the positional adjustment of laser beams is executed by moving the 2nd lens member 4 having a longer focal distance out of lens members in the optical system, so that the moving distance of the lens member required for the adjustment of the laser beams is increased and the adjustment can be easily executed.

Title: Truss structure assembling robot
Inventor: KIBE SEISHIROU
IPC: B25J13/08
Filed: 1990-09-28
Abstract: PURPOSE:To perform the assembling of truss structure with simple control by setting up a kinetic equation formed of a viscous term excluding an inertial term and a spring term on the basis of the force received by a hexaxial force sensor at the time of fitting truss structure assembling material provided with a fitting part, thus computing the speed of a hand to perform hand position control. CONSTITUTION:Truss structure assembling material is gripped by the hand 24 of an articulated robot 21 so as to be moved and fitted into the fitting part of the truss structure. The hand position control at this fitting time is performed by setting up a kinetic equation formed of a viscous term excluding an inertial term and a spring term in relation to the force received by a hexaxial force sensor 22 to compute the speed and to move the hand 24 at the computed speed. The operation required for position control can be thereby simplified, and high speed action can be performed.

Filed: 1992-09-29
Abstract: PURPOSE:To reduce sensitivities to the noise superposed on an input voltage and an offset voltage by a voltage comparing circuit 5 which amplifies and compares the difference voltage between the input voltage and a reference voltage. CONSTITUTION:When a clock phi2 is in the high level, the input voltage is sampled in a capacity 12, and the difference voltage between the input voltage and the reference voltage is sampled in a capacity 13. When the clock phi2 goes to the low level and a clock phi1 goes to the high level, the capacity 12 is connected between an input voltage terminal and a non-inverted input terminal 6 of a differential amplifier 5, and the difference voltage between the input voltage and the reference voltage is applied to the non-inverted input terminal 6, and the capacity 13 is connected between the ground and an inverted input terminal 7 of the differential amplifier 5, and the voltage obtained by inverting the polarity of this difference voltage is applied to the inverted input terminal 7. Thus, the voltage obtained by raising the difference voltage between the input voltage and the reference voltage twice is applied to the input terminal of the differential amplifier 5, and sensitiviies to the noise and the offset voltage are reduced to 1/2.

Title: Power transmission for four-wheel-drive vehicle
Inventor: HIRUTA HIDEJI
IPC: F16H48/38
Filed: 1987-10-15
Abstract: PURPOSE:To aim at the promotion of smoothness in 2WD to 4WD changeover operation by setting each pitch of a third spline and a spline tooth in a specified range of an end at the third spline side in a sleeve to two times or integral times of more than it over a pitch of another part at other splines and sleeves. CONSTITUTION:At a changeover device 36, each pitch of teeth of a third spline 47 and a spline in a specified range of an end at the side of the third spline 47 in a sleeve 48 is set to be two times or integral times of more than it over another part at other splines 45, 46 and the sleeve 48. For this reason, it comes into such a state that large backlash has occurred in an engaging part when the third spline 47 is engaged with the end of the sleeve 48. Accordingly, at turning when revolution of a front wheel exceeds that of a rear wheel, the third spline 47 tries to do relative rotation as much as a portion for the backlash to the sleeve 48, so that time, torque so far operated on the sleeve 48 vanishes into nothing at a time. Consequently, at this time operating physical force is added to the sleeve 48.
