Title: Pressing member for greenhouse sheet
Inventor: FUJITA TOSHICHIKA
IPC: A01G9/14
Filed: 1991-10-31
Abstract: PURPOSE:To provide the subject pressing member having a specific construction to give more than specific amount of elongation to a sheet relative to the thermal expansion of the sheet, thereby preventing the crease and sag of a sheet of a weather-resistant fluororesin film by the increase in temperature. CONSTITUTION:The objective pressing member 6 is composed of a clamping part 8 having a width larger than the sheet-receiving face on the sheet-receiving member 4 of a greenhouse and a pressing leg 9 extending in the direction of the length of the clamping part 8. The height of the pressing leg 9 protruded beyond the clamping part 8 is selected to give an extension of >=0.7% to the sheet 5 in the clamping of the sheet 5 made of a fluororesin film. The sheet 5 is placed on the sheet-receiving member 4 and clamped with the clamping part 8 while pressing the sheet 5 with the pressing leg 9 of the member 6. If the sheet 5 stretched in winter season is expanded by the temperature increase in summer season, the generation of crease can be prevented because the elongation is compensated by the extension of >=0.7% applied to the sheet in stretching.

IPC: H05K1/02
Filed: 1993-11-17
Abstract: PURPOSE:To enhance heat radiation by providing a heat-conductive material which is connected to the back side facing to the pellet-fixed surface of a tab, exposed from one surface of a resin sealed body and having the heat conductivity higher than that of a sealed body. CONSTITUTION:A heat conducting material 6 is arranged on the back side opposing to the fixed surface of the pellet of a tab C. The heat conducting material 6 is coupled to the back side of the tab 4C, and it is exposed from the mounting surface 2A of a resin-sealed body 2. The heat conducting material 6 is formed by the Pb-Sn alloy solder maternal having the thermal conductivity of 826X10<-4>cal/cm.sec. deg.C or thereabout. The solder material has high adhesive strength with the tab 4C, and low adhesive strength with the semi-sealed body 2. Accordingly, the thermal resistance between the back side of the tab 4C and the mounting surface 2A, which is one surface of the resin-sealed body 2, can be decreased. As the heat generated by the function of the circuit system, which is mounted on a semiconductor pellet 3, can be discharged to the outside of the semi-sealed body 2 through the heat conducting material 6, and heat radiating efficiency can be enhanced.

Filed: 1990-10-25
Abstract: PURPOSE:To use an inexpensive IC as a driving IC and to easily execute also a connecting work by coating the surface of a transparent electrode with a metallic film to form a drawing terminal string formed on a film base plate for a touch input sheet. CONSTITUTION:Metallic films 12 are formed on respective terminals of the drawing terminal string 112 formed on the metallic electrodes 11 constituted on the end parts of the film base plate 10. Since the drawing terminal string 112 on the film base plate 10 for the touch input sheet 1 is formed by coating the surfaces of the electrodes 11 with the metallic films 12, the connection resistance of a connection cable due to its connection with the wiring terminal string is extremely reduced, and at the time of executing the connecting work, the drawing terminal string 112 (112a) of the touch input sheet 1 can be clearly observed. Thereby, inexpensive ICs can be used as driving ICs and the connection work even for a high density wiring terminal string is facilitated.

Title: Press contact type semiconductor device
Inventor: KAMIJO HITOSHI
IPC: H01L21/52
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To improve the positioning accuracy and reliability of a semiconductor substrate. SOLUTION: This device has a press contact structure such that a semiconductor substrate 13 stacked by electrode layers 11a and 11b and stress absorbing materials 12a and 12b in the surface region except for the periphery is sandwiched by post electrodes 14a and 14b. In two ring members 17a and 17b, projecting parts 17A and 17B are formed along the inner circumference. When the ring members 17a and 17b are fit, end faces 17A1 and 17B2 of the projecting parts 17A and 17B directly sandwich the semiconductor substrate 13, thereby positioning the semiconductor substrate 13 for the post electrode 14a.  Since inner circumferential faces 17A2 and 17B2 of the projecting parts 17A and 17B restrict the movement of the outer circumferential faces of the stress absorbing members 12a and 12b and the movement of the outer circumferential faces of the electrode layers 11a and 11b, the situation such that a load is applied on a protective member covering the edges of the semiconductor substrate 13 is prevented.

Abstract: PROBLEM TO BE SOLVED: To perform the correct welding without deformation by controlling a piezoelectric actuator to realize the zero-touch position where a fixed electrode is abutted on a work based on the distance between the fixed electrode and a work. SOLUTION: When a robot hand 1 is driven to the teaching position after a panel 90 is positioned at the prescribed position, a fixed electrode 7 is brought into contact with the panel 90, and set to the zero-touch position where the panel 90 is not pressed.
