摘要:
The present invention relates to a polyimide metal laminate which is a metal laminate comprising a stainless steel layer/a conductor layer/a polyimide resin layer/a metal layer, wherein the conductor layer is interposed between the stainless steel layer and the polyimide resin layer as a ground, and having a strong adhesion between the conductor layer and the polyimide resin layer, thus being able to be processed and used as a hard disk suspension. Specifically, the metal laminate of the present invention is characterized in that a surface of the conductor layer in contact with the polyimide resin layer is not smooth (preferably its 10-point average surface roughness is 0.5 μm or more).

摘要:
The present invention relates to a metal laminate which is broadly used for a flexible wiring board or the like and an etching method therefor. In particular, the present invention relates to a metal laminate which includes a layer obtained by laminating a metal layer and an insulating layer, where the insulating layer is subjected to an etching process, wherein, in a surface of the metal layer which is positioned so as to come in contact with the insulating layer, respective concentrations of main metal element and oxygen element constituting the metal layer are measured from the surface of the metal layer towards inside of the metal layer in a time-elapsing manner according to AES (Auger electron spectroscopy) and a value of the thickness of a metal oxide film of the surface of the metal layer measured at a time when atomic concentrations of the main metal element and the oxygen element constituting the metal layer become equal to each other is in a range of at least 0 Å to less than 50 Å. According to the present invention, an etching time of polyimide in the polyimide metal laminate can be calculated and a flexure used for a suspension for a hard disc drive having a high productivity can be provided.
摘要:
An acoustic matching device has a water bag (64) that contains water and a water bag support frame (66) that sandwiches and supports the water bag on the left and right sides of the knee and curves along the knee cap. The water bag becomes a plate shape curved along the shape of the water bag support frame, which touches the knee cap and fits the unevenness of the knee. When an ultrasonic probe is moved along the knee cap, the acoustic matching between the knee cap and the ultrasonic probe is obtained.

A mounting unit (16) is aligned by using a mounting unit frame (58) touching the thigh and a knee-contacting portion (62) touching the knee, with the knee being bent. The mounting unit is also equipped with a probe support frame (60) used for moving an ultrasonic probe along the knee cap. The probe support frame moves rotationally about the mechanical center of the knee joint, thereby allowing the ultrasonic probe (78) to move along the knee cap while facing toward the mechanical center of the knee joint and to perform scanning of an ultrasonic beam.

Provided is an antimicrobial raw material having excellent antibacterial and corrosion-resistance properties, which can be directly formed as a film even on a plastic substrate with low heat-resistance or a substrate whereof the color or properties are likely to change due to heat, and this can be achieved at relatively low cost. The antimicrobial raw material is a laminated structure which comprises a substrate layer and a copper-tin alloy layer disposed on the substrate layer, and which has a thickness ranging from 5 nm to 200 nm. The substrate layer is made of resin, natural fiber, or paper, the resin having the deflection temperature under load being 115° C. or lower when measured in accordance with ASTM-D648-56 under a load of 1820 kPa. The copper-tin alloy layer contains over 60 at % but no more than 90 at % of copper and 10 at % or more but less than 40 at % of tin.

In a pump mechanism for ejecting liquid, an upper inside wall of a bell-shaped portion which is formed around a lower end of a first piston constitutes a guide surface inclined upward toward an axial hole of the first piston. The guide surface serves to prevent entrapping of air underneath the upper inside wall of the bell-shaped portion, or in an upper part of a metering chamber and stabilize the amount of liquid measured in each successive spraying action.

An infrared ray detecting sensor having an infrared ray detecting element located in the cool chamber of a Dewar structure comprising inner and outer cylindrical members. The chamber is evacuated to vacuum level and a getter is arranged in the chamber for ensuring the vacuum level in the chamber. A partition is arranged in the chamber between the inner end of the inner cylindrical member and the getter for forming a restricted passage and allowing communication of a gas between the getter and the infrared ray detecting element and obstructing a stray ray generated upon a radiation of the getter toward the infrared ray detecting element. The restricted passage is formed such that a ray generated upon radiation of the getter is reflected many times at the restricted passage and is dampened. The partition is roughened and colored in black.
摘要:
Provided an antimicrobial substance that includes a base material layer, and a copper-tin alloy layer 5-200 nm in thickness disposed on the base material layer, the copper-tin alloy layer containing copper in an amount of more than 60 atomic percent but not more than 90 atomic percent, and containing tin in an amount of not less than 10 atomic percent but less than 40 atomic percent. The copper-tin alloy layer includes a Cu41Sn11 crystalline phase, and a Cu3Sn crystalline phase. The Q value (Ω/(nm·Cu atomic percent)), which is derived by dividing the sheet resistance (Ω) of the copper-tin alloy layer by the thickness of the copper-tin alloy layer and the copper content (Cu atomic percent), is 1.5×10−4-6.0×10−4.
