Title: Bonding method for sputtering target
Inventor: NAKAMURA HITOSHI
IPC: B23K1/20
Filed: 1986-07-10
Abstract: PURPOSE:To improve the adhesiveness between a sputtering target and backing plate and to improve the cooling efficiency of the sputtering target by preliminarily forming a coating layer consisting of specific components on the bonding surface of the target prior to bonding. CONSTITUTION:This method prevents the deteriorated wettability of the target surface with solder by the formation of a thin oxidized layer on said surface at the time of bonding the sputtering target made of an alloy contg. >=5wt% Cr and the backing plate by In solder using a flux. More specifically, the coating layer 2 consisting of any of Cu, Ni, Co, Sn, Pb, and Fe is formed in single or multiple layers on the bonding surface of the sputtering target prior to bonding. The adhesiveness between the target 1 and the backing plate 4 is improved by executing the bonding after the In solder 3 is interposed between the target 1 formed in such a manner and the backing plate 4.

Filed: 1984-08-03
Abstract: PURPOSE:To reduce not only the exclusive volume by a pipet even if the pipet is inserted in a test tube but also the contact area of a specimen with the outer surface of the pipet and to eliminate the possibility of dripping, by constituting a tubular part elongated sufficient to prevent the substitution of air to an interior so as to bring the same into communication with a liquid sump. CONSTITUTION:In a micropipet 1 used so as to suck up a liquid by sucking action or discharge the same under pressure, a tubular part 3 elongated sufficient to prevent the substitution of air to the interior of the micropipet 1 is constituted so as to be brought into communication with a liquid sump 2. The inner caliber of said tubular part 3 can select a proper value corresponding to the viscosity of a liquid but is about 0.5-0.3mm. in usual. Even if this micropipet is inserted in a test tube, an exclusive volume is small and the contact area of a specimen with the outer surface of the micropipet is small while there is no possibility of dripping. Therefore, the distribution of a liquid is enabled by moving the micropipet side and the miniaturization of a machine can be promoted.

Title: Comparator
Inventor: GOTOU MAKOTO
IPC: H03K5/08
Filed: 1982-09-21
Abstract: PURPOSE:To prevent the generation of distortion in connecting an input source having a high output impedance, by providing a hysteresis circuit not giving any effect on an input signal between a differential comparison section and an output section. CONSTITUTION:A circuit comprising a current amplifier section 4 and a feedback section 5 is provided between the differential comparing section 1 and the output section 6 to produce equivalently a hysteresis. That is, when a current (i2-i1) in respone to an input voltage difference is inputted to the current amplifier section 4, its output current i3 is inputted to the feedback circuit 5. The feedback circuit 5 feeds back a current i4 proportional to the current i3 positively to the amplifier section 4. As a result, the relation between an input vi and an output v0 has a hysteresis characteristic. Since this circuit produces the hysteresis characteristic without giving any effect on the input signal, even if a signal source having a high output impedance is inputted directly, no distortion is produced in the AC input.

Filed: 1994-06-23
Abstract: PURPOSE:To expand a tolerance range of individual magnetic head performance and to reproduce a high quality image by controlling a variable amount of a reproducing output due to a pseudo gap not by individual magnetic head but by combination of paired magnetic heads. CONSTITUTION:Plural magnetic heads 2 are loaded on a rotary drum 1a of a rotary head device 1. Plural magnetic heads form sets of a pair respectively, and the magnetic head A serves for an A channel or an R channel, and the magnetic head B serves for a B channel or an L channel. Further, a tape 3 is wound around the device 1 and runs rightward, and the drum 1a is rotated counterclockwise. In the magnetic head 2, the pseudo gap is formed on a joint part between a core 4 and a metal layer 5, and the pseudo gap affects the essential reproducing output. That is, by the influence of the pseudo gap, the waviness occurs in the reproducing output following a change in reproducing frequency F. The waviness is controlled by the combination of the paired magnetic heads, and the tolerance range of the individual head performance is expanded.
