Patent JP-H02253628-A (JP)
Title: Manufacture of semiconductor device
Inventor: KIKKAI AKIRA
IPC: H01L21/321
Filed: 1989-03-28
Abstract: PURPOSE:To improve reliability and to suppress an increase in cost by employing a material which is scarcely plated as a first metal film, forming a metal bump, then exposing the first metal film, and then plating a third metal film. CONSTITUTION:First, second metal films 4, 5 such as Ti, Cu, etc., are formed on a whole semiconductor substrate 1 including pad electrodes 2 by a sputtering method. In this case, the film 4 uses metal which is scarcely plated, and the film 5 uses metal which can be plated. A metal bump 7 such as Cu bump is formed on the exposed film 5 by electrolytically plating, and a third metal film 8 such as Au, Pb-Sn, etc., is formed on the substrate 1 including the bump 7 by electrolytically plating or electrolessly plating method. In this case, since the film 8 by plating is scarcely adhered onto the film 4, it is resultantly formed only on the bump 7. Thus, the bump having high reliability and low cost can be obtained.

Title: Hot water supplying device
Inventor: TAKEUCHI TAKAO
IPC: F24H1/10
Filed: 1988-03-28
Abstract: PURPOSE:To prevent the quantity of hot water supplied from being reduced to or below a water quantity for an extinguishing operation during an operation of a burner and prevent a hunting phenomenon of the burner from occurring, by automatically changing a preset temperature of supplied hot water to a fixed temperature when the quantity of hot water supplied reaches a predetermined constant value. CONSTITUTION:A controller 5 for controlling the ignition, extinguishment and combustion quantity of a burner 2 according to an output from a water quantity sensor 7 is provided with a supplied hot water temperature calculator 5d. When the signal from the sensor 7 is lowered to a predetermined value approximate to a water quantity for an extinguishing operation, a preset higher supplied hot water temperature Hsh is automatically lowered to a predetermined lower supplied hot water temperature Hsl by the calculator 5d, and the lowered temperature value is inputted to a combustion quantity calculator 5b. As a result, the temperature of hot water supplied from a heat exchanger 1 is lowered, and the burner 2 is prevented from being extinguished due to an increase in the quantity of hot water supplied by an operation of a hot water tap or the like. When the quantity of hot water supplied is increased to or above a predetermined quantity during an operation under the lower supplied hot water temperature Hsl, the hot water temperature calculator 5d automatically raise the temperature Hsl to the higher supplied hot water temperature Hsh, which is inputted to the combustion quantity calculator 5b, thereby switching the operation to a high-output operation.

Abstract: PROBLEM TO BE SOLVED: To attain the preserving of important data for the long term by interrupting the driving power source of one pair of upper and lower hand members during the movement of the accessor of an automatic transfer robot and clamping a cartridge with an energizing mechanism to prevent the damage while transferring the cartridge. SOLUTION: After a control part moves a hand mechanism 7d to a cartridge clamping position by supplying a power source to a P system driving circuit sliding the picker part 7g of an accessor 7 with respect to a tilt base 7f, the part stops a current supply to an H driving circuit for opening and closing the hand members of the picker part 7g of an accessor 7 and makes the hand mechanism 7d clamp a cartridge with an energizing force. When it confirms the clamping of the cartridge, it makes the cartridge to be in a fixed state mechanically by stopping the supply of the current to the H driving circuit until it drives the hand parts.  Consequently, even when the defect of a circuit is generated in the hand mechanism 7d at the time of the movement of the accessor 7, it is possible to hold the cartridge safely by preventing the cartridge from being dropped and the cartridge from being brought into contact with respective members in a moving path.
