Inventor: KURODA SATORU
IPC: H01L21/30
Filed: 1980-09-19
Abstract: PURPOSE:To eliminate the production of inferior patterns by a method wherein a plurality of lines of gas blow-off ports directed to the outside of a base plate is arranged outside the base plate which is held and retained and thereby developing liquid dripped from above the base plate is prevented from creeping round onto the back surface of the base plate. CONSTITUTION:A wafer 19 is set to a main chuck 12 and dry nitrogen gas is blown against the back surface 20 of the wafer 19 from a plurality of lines of the blow-off ports 17. And, while the main chuck 12 being rotated, the developing liquid 22 is dripped on the wafer 19, whereby the development of a resist is conducted. At this time, the developing liquid, creeping round toward the back surface of the wafer, is prevented from entering onto the main surface 14 of the chuck by the nitrogen gas being blown-off. By this constitution, the developing liquid is prevented from creeping round onto the back surface of the wafer and thus the defects of the pattern can be eliminated.

Abstract: PURPOSE: To reduce the contact resistance of a switch, by applying necessry contact pressure only when the switch is in ON.  
     CONSTITUTION: A spring piece 10 of a switch spring plate 6 is slid in interlocking with the sliding operation of a handle 2, thus sliding and contacting a 1st contact portion 15 to one surface of the spring piece 10 all the time. When the handle 2 is in ON, a spring contact portion 11 at a nose at the other surface side of the spring piece 10 is slid and contacted to a 2nd contact portion 18. The 1st contact portion 15 is shaped to a free end of a contact plate 12 with spring property, thus pushing the contact portion 15 to one surface of the spring piece 10 all the time. That is, the contact portion 15 contacts with the one surface side of the spring piece 10 and the contact portion 18 with the other surface side respectively when operating the handle 2, and the movement of the spring piece 10 is regulated, thus obtaining adequate contact pressure at the contact portions 15, 18 by relative location relation- ship between the contact portions 15, 18, then reducing the contact resistance of a switch. Since the spring piece is not shaken by vibration, impact, etc. as other advantages, these is no change with the passage of time, thus ensuring excellent contact condition for a long term.

Abstract: PURPOSE: To provide large bending rigidity in the width direction of a belt, and to secure the adhesivity by making the material of the weft in the width direction of a conveyor belt to be used for the fiber cloth of the aliphatic polyamide having the aromatic ring. CONSTITUTION: In a rubber belt for a conveyor with the fiber cloth as a core, the material of the weft in the width direction of the conveyor belt to be used in the fiber cloth is made of the mono filament of the aliphatic polyamide (MX nylon) having the aromatic ring in the principal chain of the chemical structure. For example, the cloth layer conveyor belt A comprises an upper cover 1, a lower cover 2, an ear cover 3, and a cloth layer 4 where the weft is made of monofilament of MX nylon of ϕ0.6, and the warp is made of the double-twisted nylon 6 of 840 denier. Because the mono-filament of MX nylon is used as the material of the weft of the fiber cloth as the core, large bending rigidity can be obtained in the width direction of the belt, and the adhesivity to the rubber is superior to that of the mono-filament of polyester.

Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To shorten the delay time without increasing the area of an IC (integrated circuit) and also to shorten the design time of the IC by correcting only the wiring path having the delay time that does not satisfy a standard. SOLUTION: This method/device consists of a storage 101, a controller 102, an input device 103 and a display device 104. The storage 101 stores the processing procedure of the controller 102 and a data base necessary for the wiring placement design of an IC. Then the controller 102 operates based on the processing procedure stored in the storage 101 to generate the display contents of the device 104 and also generate the placement wiring data based on the contents inputted to the device 103 by an IC designer. At the same time, the controller 102 confirms whether the delay time of every wiring path is smaller than the prescribed value set previously and then shows the result of this confirmation on the device 104 after a placement wiring is designed.  When a correction mode is inputted to the device 103, the delay time is shortened (corrected) for only the wiring path having the delay time that exceeds the prescribed value.

Abstract: PURPOSE:To suppress vibration of drill, to improve fine boring accuracy and the service life of drill and to automate the system by regulating the fitting condition of the bore section of a spring collet and the diameter of a drill shank then mounting/dismounting a drill. CONSTITUTION:The dimension at the caliper section of a spring collet 2 is set larger by 0.05mm than the shank diameter of a drill 1 by regulating the position of a push rod 7. The dimension at the caliper section is set the shank diameter of the drill 1 plus 2mum when the caliper section is chucked thus holding the drill 1 stably with quite small differential angle theta2 at the caliper section. Consequently, vibration is limited within 1.5mum without requiring adjustment even when the drill 1 is replaced.
