Abstract:
A wiring substrate to which an IC chip is connected through soldering is formed from ceramic having electrode pads formed of a metallization layer. At least one nickel layer is formed on the electrode pads. The nickel layer has a thickness in the range of 2.5 &mgr;m to 8 &mgr;m. The nickel layer is preferably composed of a plurality of plated layers, and the outermost layer thereof is preferably formed through Ni-B plating. A gold plating layer is preferably formed on the outermost nickel layer. Further, heating is advantageously performed at least one time during the formation of the plurality of nickel layers.

The thermal spray coating material powder is a mixed powder comprising (A) 98-70% in volume of Cu based lead bronze alloy powder and (b) 2-30% in volume of Al powder or Al based alloy powder.
Abstract:
An ion implanting apparatus for irradiating a material, for example, a semiconductor wafer, with an ion beam generated at an ion source, for implanting the ion into the material, is provided with a magnet at a side of the material opposite to a side into which the ion is irradiated. Thereby, the implantation is performed without charging thereon and with a high yielding ratio.
Abstract:
To improve the safety of the interlocking switch circuit comprising a monitor switch, primary switch and secondary switch which are on/off by the opening and closing of the electronic range door in order to control the operation/nonoperation of the microwave generation device of the electronic range. The above switches are taken as relay contact points respectively, so as to be able to operate the on/off of each switch from outside. By this, the detection jig is decreased, the detection time period is also shortened and a cause of the safety decreases due to the increase of the efficiency removed. In addition, the switch which turns the on/off of the microwave generation device of the electronic range is adapted to increase the safety of the interlocking switch circuit by being arranged independently.
Abstract:
The noise control system of this invention includes: a noise detector for detecting a noise generated from a noise source in order to output a noise detection signal; an adaptive filter portion for outputting a control signal based on the noise detection signal so as to cancel the noise; a control loudspeaker for receiving the control signal that is to radiate a control sound to a predetermined region; and an error detector for detecting a residual error of the noise and the control sound in the predetermined region, wherein the adaptive filter portion includes: an adaptive filter for receiving the noise detection signal and processing the noise detection signal to output a control signal; an IIR filter section for receiving the noise detection signal, performing a filtering process to the noise detection signal according to a predetermined frequency characteristic, and outputting a first processing signal; an operation section for receiving the first processing signal, performing convolution with the first processing signal and a predetermined transfer function, and outputting a second processing signal; and a multiplying section for receiving the second processing signal and the error signal, multiplying the second processing signal by the error signal, and outputting an update signal for updating coefficients of the adaptive filter to the adaptive filter, the predetermined frequency characteristic and the predetermined transfer function being determined based on a control transfer characteristic from the control loudspeaker to the error detector.
Abstract:
In a video camera in strobe mode, when a condition for strobe light emission is ready, the aperture of an iris is reduced and the gain of an AGC amplifier is fixed at a predetermined value. Accordingly, a dark image representing the condition ready for strobe light emission is displayed on an electronic view finder, and in addition saturation of charge accumulation is prevented.

Abstract:
Defective portions, such as black dot defects, in an emulsion layer of an emulsion mask such as a photomask are repaired or removed by irradiating an ultraviolet laser beam from a laser oscillator, preferably an excimer laser. The laser beam is passed through an adjustable aperture for shaping and is then projected onto defective portions in dimensional alignment, whereby the defective portions are destroyed. In order to ensure that only the defective portions are destroyed, the image of the aperture projected on the emulsion layer is observed so as not to cover the emulsion mask where defective portions do not exist. Defective portions such as white defects can also be repaired by using additional procedure together with the irradiation of the laser beam.
Abstract:
A vibrating column pump pumps liquid by making use of liquid vibration generated at the time when the vibrating pipe is vibrated in a longitudinal direction thereof. The vibrating column pump comprises a vibrating pipe for pumping liquid therethrough, flexible pipes for connecting both ends of the vibrating pipe with a stationary suction pipe and a stationary outlet pipe, vibrating means for vibrating the vibrating pipe in a longitudinal direction thereof, and retainer means for removably retaining the vibrating pipe in such a manner that the vibrating pipe is removably connected to the vibrating means. The liquid contacting unit including the vibrating pipe and the flexible pipes is separated from the vibrating means so that the liquid contacting unit is disposable and can be easily replaced with a new one.
Abstract:
A vacuum contact printing device comprises a pair of frame members for supporting a pair of originals disposed on both sides of a base member and a pair of transparent plates disposed outside the frame members. A first vacuum chamber is formed between the paired originals and a second vacuum chambers are formed between the paired originals and the transparent plates. A vacuum device is connected to the first and second vacuum chambers for exhausting inner air in the first and second chambers for reducing inner pressures thereof and being capable of releasing the vacuum condition at least in the second vacuum chamber. There is provided an exposure apparatus to which the original contact printing device is applicable, in which original contact devices are movable from exposure positions to other positions and a supplemental original contact device is movable to the exposure position. The original contact device includes a first slide mechanism for supporting a first frame member so as to be movable in a direction normal to the base member and a second slide mechanism supported by the first frame member for supporting a second frame member so as to be movable in a direction normal to the base member.
