Abstract: PURPOSE:To inhibit the generation of a flaw in the surface of a wafer in post- processes, and to improve the yield of products by previously coating the surface of the semiconductor wafer, to which a wafer process is completed, with an epoxy resin while exposing only a bonding pad. CONSTITUTION:The bonding pads 5 in desired number are formed to the fringe sections of each pellet of the semiconductor wafer to which a predetermined diffusion process is completed and dicing lines 3 are cut in, and the surfaces of the pads 5 are exposed while the surface of the wafer 1 is coated with a surface protective film 6 made of PSG, etc. as the film 6 is applied to the edge sections of the pads 5. Bonding wires are fitted to the pads 5 or the wafer is cut along the lines 3, but a film 11 consisting of the epoxy resin is formed previously on the film 6 being at present on the insides of the pads 5 in order to protect these surfaces at that time. Accordingly, the generation of damage of the wafer in post-processes is prevented, and the wafer is pelletized and the film 11 is removed.

Title: Device and method for cooling work roll for hot rolling
Inventor: NAKAMURA HIROSHI
IPC: B21B27/10
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To attain uniform cooling for the entire work roll by pouring lukewarm water on the water retained on a wiper in the center of the roll, flowing to the left and right the retained water overflowing from the center, and discharging it outside the wiper. SOLUTION: Retained water 12 at both ends of a roll having a small temperature rise is discharged outside a wiper by opening, through the operation of a cylinder 16, a discharging port 18 provided in the lower part of the wiper 10. In addition, the retained water 12 in the center part having a large temperature rise is blocked as it is by a weir, with a lukewarm water poured in from a nozzle to the retained water 12 which is heated by the work roll 2 to a high temperature. This water pouring lowers the temperature of the retained water 12, reducing the temperature rise of the roll 2. Further, the retained water, overflowing the weir by the pouring of the lukewarm water, moving to the adjacent weir and further to the next weir, is discharged outside the wiper through the opened discharging port 18. Thus, both ends of the roll 2 with a small temperature rise is prevented from being cooled.

Abstract: PURPOSE:To improve the reliability of medium delivery by providing a pressure regulating means to convert the pressing force of a partition plate according to the thickness of the medium held between a pressing plate and a delivery roller, in a copy delivery device such as a facsimile device. CONSTITUTION:When copies 1a are loaded on a setting plate 4a, and inserted between a delivery roller 8a and a pressing plate 9b, the tip of the pressing plate 9b is pushed up to increase the pressing force, and at the same time, according to the bending of spring 14, a lever 12a is rotated in the direction of the arrow B around a support shaft 13 as the center, the tip of the lever 12a is abutted to a separator 10a, and pressed to the delivery roller 8a.

Title: Test circuit for semiconductor device
Inventor: IMAMURA HIROHISA
IPC: H01L21/822
Filed: 1986-08-08
Abstract: PURPOSE:To use a pin which is utilized as a test pin for other functions by applying a negative voltage which is not the normal operating voltage of a circuit to an input terminal. CONSTITUTION:In stand-by mode, a control signal HALT applied to a control terminal 5 is set to '1' first. At this time, a 1st P channel type transistor (TR) 1 turns off to cut off a through-current from a power source 8. In normal operation, the signal HALT is set to '0'. Then the TR 1 turns on. In this state, when an input voltage (position voltage) is applied to an input terminal 4, a 2nd TR 2 turns on. The circuit composed of TRs 1-3, therefore, becomes a ratio circuit. Then when a test is conducted, the signal HALT inputted to the terminal 5 is set to '0'. Then when a negative voltage is applied to the terminal 4, the TR 1 turns on. Further, a P channel type TR 3 also turns on because '0' is inputted.
