摘要:
A conical-frustum-sputtering target for use in a magnetron sputtering apparatus for forming a film on a planar substrate. The sputtering target includes a target member having at least a conical-frustum-shaped surface including a first surface portion parallel to a center portion of the planar substrate and spaced a first distance therefrom, a second surface portion parallel to at least an extension of a peripheral portion of the planar substrate and being spaced a second distance therefrom wherein the second distance is less than the first distance, and at least one-third surface portion inclined with respect to the planar substrate for interconnecting the first surface portion and the second surface portion. By utilizing such a sputtering target, a film having a uniform thickness can be formed on a substrate having side steps and such can be utilized to deposit metallic thin film for a minute wiring pattern and can be applied to a larger substrate.

The present invention relates to a method for filling small via holes provided to insulating film on a wafer to expose parts of the underlayer of the wafer by metal by means of CVD, and an apparatus therefor. The gist of the present invention lies in that, before CVD is conducted, a surface cleaning treatment of small via hole bottom underlayer surface and a stabilization treatment of insulating film surface activated thereby are carried out successively or simultaneously and optionally an anti-corrosive treatment is applied to underlayer surface, and then the CVD treatment is conducted without exposing the underlayer metal subjected to above treatments to the air. The present invention provides an effect of enabling via filling by metal which shows good selectivity and gives a low interfacial resistance between underlayer metal and filled metal.

In the optical fiber collimator according to the invention, a transparent block having a refractive index that is substantially the same as the refractive indices of the lens and optical fiber is disposed between the lens and ferrule so that the block contacts the lens, ferrule, and optical fiber. The thickness of the block in the direction of beam transmission is set to be the same as the distance to the focal point from the end surface of the lens that is determined by the diameter and refractive index of the lens and the refractive index of the block.

A metal gasket for cylinder head 1 of plate lamination type, comprises two base metal plates each of which includes cylinder holes, circumferential beads formed around the peripheries of individual cylinder holes, cooling water holes formed outside the peripheries of the circumferential beads, and an outer bead formed and positioned so as to entirely enclose the circumferential beads and the cooling water holes, wherein the circumferential beads of the two base plates are aligned in the direction of thickness of the metal gasket. Claw-like protrusions are provided for one of an outer step adjustment metal plate and extending from the cooling water jacket to the outer edges of the base plates, and a thicker inner step adjustment metal plate 4 extending from inside the circumferential beads to the cooling water jacket, into engagement holes in the other of the inner step adjustment plate and the outer step adjustment plate.
摘要:
A motor controller includes: an estimated temperature calculating section that calculates and stores an estimated temperature of a motor, and a control section that can perform a drive control of the motor only when this estimated temperature is not larger than a predetermined value. When the motor is stopped, a second temperature gradient while the temperature of the motor decreases from a stop-time temperature to a predetermined first set temperature is stored in correspondence to the stop-time temperature. The first temperature gradient corresponding to the estimated temperature at a time when the motor is stopped is calculated by using the first temperature gradient storing means, if the estimated temperature stored in the estimated temperature storing means when the motor is stopped is larger than the first set temperature. The estimated temperature stored in the estimated temperature storing means is updated according to a lapse of a stopping time of the motor by using the first temperature gradient calculated by the first temperature gradient calculating means.
摘要:
A controller is operable in one of a plurality of operational modes, which include an estimated temperature computation performing mode for performing computing of an estimated temperature of the motor and an estimated temperature computation non-performing mode for stopping the computing of the estimated temperature of the motor. An operational mode of the controller is changed from the estimated temperature computation performing mode to the estimated temperature computation non-performing mode according to a predetermined condition in a stopped state of the motor.

A vibration apparatus for a molding box which enlarges the range in which a vibrating force can be increased and decreased. In the apparatus, a first gear pulley 16 for rotating a first rotary shaft having a first eccentric weight fixed thereto and a second gear pulley 17 for rotating a second rotary shaft having a second eccentric weight fixed thereto are disposed on the same plane, and similar third and fourth rotary shafts are disposed immediately below the first and second rotary shafts, respectively. An endless timing belt 37 is passed around a prime mover gear pulley 33 and a gear pulley 36 disposed on a slidable base 31 capable of horizontal displacement in such a manner as to extend from the lower side of the first gear pulley 16 to the upper side of the second gear pulley 17 and from the upper side of the fourth gear pulley 19 to the lower side of the third gear pulley 18, and the slidable base 31 can thus move in a direction parallel to the timing-belt 37.
