Title: Electrode for semiconductor device, its manufacture, and the semiconductor device
Inventor: GO TSUTOMU
IPC: H01L21/60
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To provide an electrode for semiconductor device which is capable of preventing the defective fracture of solder bumps when the electrode is manufactured by electroless plating, etc., and a method for manufacturing the electrode. SOLUTION: On the surface of an electroless barrier metal film 22 formed on the surface of a pad 20, a thin solder precoat film 23 is formed. When the precoat film 23 is formed, the melting of Ni in the precoat film 23 from an electroless Ni-P film 22a constituting part of the barrier metal film 22 is suppressed, and the formation of a P-rich amorphous layer in the Ni-P film 22a is prevented. As a result, the growth of an Ni3 Sn4 intermetallic compound layer 24 in the height direction is checked and a thin intermetallic compound layer 24 has bonding face 24a which is bonded to nearly the entire surface of the Ni-P film 22a is formed. Since the intermetallic compound layer 24 has a strong bonding force, the defective fracture of a solder bump 11 can be prevented.

Title: Fault reporting system
Inventor: HASEGAWA ISAO
IPC: G06F11/22
Filed: 1989-05-08
Abstract: PURPOSE:To suppress the enlargement of damage by informing an operator of an event, in the case a diagnostic processor is in an inoperable state, and a fault is generated in a body system computer. CONSTITUTION:When a diagnostic processor 101 becomes inoperable, a fault displayed on an inoperability display part 110 is reported to an operator station 201 through a diagnostic processor inoperability report line 111. The operator station 201 receives this report and displays it to an operator. In the case the diagnostic processor 101 is in an inoperable state, and also, a fault is generated in a body system computer 1, the body system computer 1 reports its result to the operator station 201 through a fault state report line 121, based on the self-diagnosis. In this case, although a fault processing to a fault of the body system computer 1 is impossible, at least a fact that the body system computer 1 becomes inoperable can be reported to the operator. In such a way, the enlargement of damage is avoided.

The apparatus is designed to maintain stable combustion under the condition that pressure P 1  in burner 2 is 12mmAq and pressure P 2  in combustion chamber 3 is 4mmAq. Therefore, if density of intake air is increased by reason of lowering of outdoor temperature and P 1  is raised, revolutional speed of burner motor 9 is lowered. The above control can be achieved alternatively by controlling the opening of damper.

Title: Oil hydraulic pump
Inventor: SASAKI SUSUMU
IPC: F04B23/02
Filed: 1979-09-10
Abstract: PURPOSE: To permit a compact plunger-type oil hydraulic pump for a cutting tool or the like to produce a high pressure by providing a cylinder divided into two by means of a valve in the oil tank tightly filled with oil, omitting a suction valve, and making the ratio of the high-pressure chamber volume to the dilivery smaller.  
     CONSTITUTION: The pump is operated by the reciprocation of a plunger 9 in the front chamber A of a cylinder 10 by the drive of a motor 3 through a cam 7 on the eccentric portion of a driving shaft 4. When the plunger 9 is moved backward by the force of a spring 8, a negative pressure is applied in the front chamber A because a valve seat 11 has been closed by a switching valve 14. Consequently, when the plunger 9 opens a suction port 12, operating oil filling an oil tank 1 enclosed is sucked into the front chamber A. When the plunger 9 changes its motion to the discharge stroke, the operating oil in the front chamber A flows into the rear chamber B against the force of a spring 13, and is discharged from a discharge port 15. When the quantity of the oil in the oil tank 1 decreases, the pressure in the tank 1 lowers, and this causes a flexible bag 25 opened in the atmosphere to expand. Consequently, the pressure in the oil tank 1 is kept equal to the atmospheric pressure, and so the pump smoothly operates without lowering its function.
