Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To improve the workability and performance by arranging a core material between a surface material made of resin and a back surface material, and while providing a linear reinforcing material in a male type connection part and a female type connection part respectively formed in an upper and a lower ends of the surface material. SOLUTION: A fixing part 14 is formed of a fixing surfaces 15, 16 so as to double the strength at the time of placing this fixing part 14 in a building frame with a fixing tool such as a nail, and the generation of breakdown of the fixing part 14 due to the external force is prevented. At the time of fixing a building panel A to the building frame with the fixing tool, a clearance 14a facilitates the movement of the fixing surface 16. With this structure, even in the case where the panel A is extended by the heat, deformation of the panel A and peeling of the panel A from the building frame is prevented. A fixing hole formed in the fixing part 14 is formed into the lateral long shape so as to facilitate the thermal extension of the resin surface material 11 in the longitudinal direction. Furthermore, a linear reinforcing material 18 is arranged in the clearances 9a, 14a, and the tensile strength is generated so as to prevent the breakdown of the upper and the lower end of the surface material 11. Construction is thereby facilitated, and the weather resistance, vibration resistance and the wind pressure resistance are improved.

Title: Manufacture of porous silicon
Inventor: TAKASUKA EIRYO
IPC: H01L21/306
Filed: 1993-10-22
Abstract: PURPOSE:To control the light emitting characteristics such as luminous efficiency, luminescent color, etc., by feeding intermittent formation current. CONSTITUTION:Holes produced in a silicon substrate and fluorine ions (f<->) in a formation solvent during anode formation step are concerned with the formation of a porous silicon layer. Accordingly, the movement of holes and fluorine ions in these reaction systems is modulated by the electric field imposed on the reaction systems to change the formed porous silicon structure for changing the light emitting characteristics of the porous silicon. That is, a pulsive current in equal conduction time tH and current stoppage time tL as the formation current is conducted. Through these procedures, the light emitting intensity can be changed by the same formation amount of electricity. Furthermore, the porous silicon can be manufactured by the less formation amount of electricity than that in the conventional cases thereby enabling the energy cost to be cut down.

Title: Mounting of semiconductor chip
Inventor: SEGAWA MASAO
IPC: H01L21/607
Filed: 1988-10-20
Abstract: PURPOSE:To eliminate a defect in a connection of a lead by a warp of a tool by a method wherein, after all leads have been bonded collectively by using a large-sized tool, a part where the defect in the connection has been caused is bonded again at each lead by using a small-sized tool using heat and ultrasonic waves jointly. CONSTITUTION:An inner-lead bonding operation of leads 5 to aluminum electrodes 8 on a semiconductor chip 7 is executed via bumps 4 by using a large-sized bonding tool 6. Two to four pins which are not connected to the central part on long sides of the chip are caused because of a recess in the central part of the tool 6; a defect in a connection is corrected at each pin by using a smallsized tool 10 which uses heat and ultrasonic waves jointly. As the tool 10, it is preferable to use a tool where uneven parts are formed at its tip part because the bonding operation can be executed easily. Thereby, where a film carrier is mounted on the large-sized semiconductor chip 7 having many pins, it is possible to eliminate the defect in the connection of the lead by a warp of the tool 6.
