Title: Production of metallic joined body
Inventor: HIRAYAMA KAZUO
IPC: H01L23/373
Filed: 1993-09-13
Abstract: PURPOSE:To provide an Al metallic joined body which hardly generates deformation and has good heat radiation property by successively laminating plural Al-Si alloy layers varying in Si contents in order of the layers of the lower Si contents from the Al layer side and subjecting these layers to press joining by an HIP method. CONSTITUTION:The plural Al-Si alloy layers varying in the Si contents are laminated by laminating the layer of the lower Si content on the first layer side and are joined by the hot hydrostatic pressing method (HIP) in the case of producing the joined body consisting of Al as the first layer and Al-Si alloy as the second layer. The pressure is preferably about 50 to 150MPa and the temp. 559 to 350 deg.C. For example, the Si content of the Al-Si alloy on the outermost side of the second layer is confined to about 50% as an upper limit and the layer having the Si content changing in a range of 5 to 50% is used. The number of the layers varying in the Si contents is usually 3 to 5 layers and the thickness thereof is specified to about 0.5 to 20mm. As a result, the blanks varying in thermal properties are securely joined and the joined body obtd. in such a manner hardly generates the deformation, such as warpage and has the good heat radiating property.

Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic vibrator transducer of simple construction for making stable resonance vibration by inserting laminated type piezoelectric elements into recessed parts of a prismatic elastic body before putting a holding elastic body in to make it an ultrasonic vibrator transducer and applying voltages of the same phases as each other or opposite phases to the piezoelectric elements. SOLUTION: On the front and the rear of a prismatic elastic body 11, a pair of laminated type piezoelectric elements 13 are held at a certain inclined angle, and on the end face thereof, a friction element 15 is stuck. When alternating voltage of a prescribed frequency of the same phases as each other is applied to the pair of the laminated type piezoelectric elements 13, longitudinal resonance vibration is excited in the prismatic elastic body 11. When voltages having opposite phases to each other are applied to the pair of the laminated type piezoelectric elements 13, torsion resonance vibration is excited in the prismatic elastic body 11.  When voltages having the phases different by π/2 from each other are applied to the pair of the laminated piezoelectric elements 13, longitudinal resonance vibration and torsion resonance vibration are simultaneously excited, and at the position of the friction element 15, ultrasonic elliptical vibration is excited.

IPC: H03L7/06
Filed: 1990-09-21
Abstract: PURPOSE:To reduce jitters at the time of multistage-repeating by varying an interval in a phase synchronous state and temporarily controlling the number of division as against a reference clock in accordance with a phase compared result on the advance and lag of a phase in respective intervals. CONSTITUTION:A phase correction period control part 5 controls a control period as against the number of division and the number of division is not frequently controlled. Namely, the phase correction period control part 5 decides the phase correction period and a phase correction control content at that time based on a dividing output 2 and the advance and lag of the phase. A frequency-dividing part 6 controls the number of division at first at the phase correction period through a division number deciding part 4. Namely, time when phase correction is executed is set to be a new interval start time and similar phase correction control is executed hereafter. Thus, a high speed circuit operation is eliminated and an NRZ signal can be multistage-repeated and transmitted in a state where jitters are reduced.

Filed: 1990-09-18
Abstract: PURPOSE:To easily reduce the oscillation generated in a belt driving system to feed a magnetic tape with a high precision by forming the flange part inside face of a belt pulley with a material whose coefficient of friction is lower than that of the belt contact face of the pulley. CONSTITUTION:A low-friction material is used in a flange part 902A of a pulley 9 used as a reel driving mechanism to suppress the occurrence of oscillation of a belt 8 due to contact between the side face of the belt 8 and the flange part 902A of the pulley. That is, a belt side face 802 is brought into contact with the flange part 902A of the pulley 9 when the belt 8 is oscillated, but the belt 8 is not lifted to the outside periphery of the pulley 9 because of the low coefficient of friction of the flange part 902A, and the belt 8 is not oscillated, and the running position is controlled to prevent the belt 8 from slipping off the pulley 9. Thus, oscillation generated in the belt driving system is easily reduced, and the magnetic tape is fed with a high precision.
