Title: Testing of printed circuit board
Inventor: OBARA HIDEYUKI
IPC: G01R31/02
Filed: 1992-10-16
Abstract: PURPOSE:To test a printed circuit board regardless of the presence of terminal resistance. CONSTITUTION:A plurality of probe pins 1, 1... to which probe resistors RP having a common resistance value are connected are simultaneously brought into contact with the respective leads 3a, 3a... of the LSI element 3 mounted on a printed circuit board 2 and the resistance value of the net connected to either one of the leads 3a, 3a... is measured. When the measured result is equal to the expected value of the resistance value in the closed circuit containing the probe resistors RP, the printed circuit board is judged to be good product and, when the measured result is lower than the expected value, the printed circuit board is judged to be inferior.

Title: Semiconductor device
Inventor: MACHIDA KAZUMICHI
IPC: H01L21/60
Filed: 1985-12-10
Abstract: PURPOSE:To conduct ball bonding with a comparatively large ultrasonic output, and to join a copper wire and an electrode excellently by forming the electrode in three-layer structure consisting of a lower electrode layer, a barrier layer and an upper electrode layer and shaping the barrier layer by using a material harder than the electrode layers and difficult to be diffused. CONSTITUTION:An aluminum film is evaporated onto a semiconductor chip 2 through an evaporation method to form a lower electrode layer 13a, a chromium film is also evaporated onto said lower electrode layer 13a through the evaporation method to shape a barrier layer 13b, and an aluminum film is evaporated onto the barrier layer 13b through the evaporation method to form an upper electrode layer 13c, thus shaping an electrode 13 having three-layer structure. Accordingly, when the electrode for the semiconductor chip is formed in three-layer structure having the barrier layer, the damage of the semiconductor chip can be prevented because a ball collides with the barrier layer even when the upper electrode layer is rejected to the periphery of a junction section by ultrasonic vibrations and the ball does not collide with the semiconductor chip, and the damage of the electrode is obviated because the lower electrode layer is not expelled to the outer circumference of the junction section.

Filed: 1986-11-27
Abstract: PURPOSE:To preserve a plastic magnet molding material for a long period by separately using a main agent and a hardener of ambient solid 2-liquid type thermoset resin to mix rare earth magnetic powder covering the surface therewith. CONSTITUTION:A main agent and a hardener use ambient solid 2-liquid type thermoset resin. More particularly, epoxy resin of 2-liquid type epoxy resin or urethane resin having 40 deg.C of melting point or softening point is preferable in view of electric characteristics, strength and adhesive with magnetic powder. Rare earth element magnetic powder is of intermetallic compound magnetic powder which contains as basic composition rare earth metal and transition metal, and uses a covering method for preventing the oxidation of the surface of the magnetic powder. The total amount of the main agent and the hardener of ambient temperature solid 2-liquid type thermoset resin to be used for coating is normally 0.5-15wt. parts with respect to 100wt. parts of the rare earth element magnetic powder. Thus, since the reaction of the main agent and the hardener is scarcely proceeded and the rare earth magnetic powder is not oxidized, its preservation stability is improved.

Abstract: PURPOSE: To measure the flow velocity of a fluid with high accuracy without receiving any influence from eddy and turbulent currents by simultaneously generating two ultrasonic signals from two points on the upstream and downstream sides of the same propagating route and measuring the propagating time of the signals. CONSTITUTION: A control section 41 simultaneously sends control signals to transmission-reception units 40 and 42 and sensor sections 15a and 15b simultaneously unit ultrasonic signals to an object through transmitting sections 43a and 43b and input-output circuits 45a and 45b. The control signals are also supplied to a counting section 49 so as to make the section 49 simultaneously start the counting of clock pulses. The received signals of the sensor sections 15a and 15b are supplied to the counting section 49 respectively through the circuits 45a and 45b and receiving sections 47a and 47b and separately stop the clock pulse counting operation of the section 49. As a result, the propagating time of the ultrasonic signals in the forward and reverse directions can be found.  These time data are sent to an arithmetic processing section 51 and the section 51 calculates the flow velocity of a fluid from the propagating time in the forward direction and that in the reverse direction.
