Title: Substrate for optical disk and its production
Inventor: OKUDA KOSHO
IPC: G11B7/24047
Filed: 1995-05-23
Abstract: PURPOSE: To suppress the warpage angle of a disk within ±5mrad even under wide environmental conditions by allowing the warpage angles varying with the inner and outer peripheries of the disks which occur in later stages and providing the disk with such warpage to recess to the recording surface side. CONSTITUTION: The substrate surface 58 between the inner peripheral part 54 on the through-hole 52 side of the substrate 50 and the outer peripheral part 56 of the substrate 50 are formed by having the recessed warpage. The difference between the warpage angle θa of the inner peripheral part 54 and the warpage angle θb of the outer peripheral part 56 in the diametral direction of the substrate 50 is preferably 2.0 to 5.0mrad and is more particularly preferably 3.0 to 4.0mrad. The disk having a plane shape over the entire surface is obtd. if a recording layer, interference layer, reflection layer, etc., are formed on the substrate 50 formed in such a manner. The warpage angle of the disk is thus suppressed within ±5mrad even under environment of a high temp. and high humidity or low temp. and low humidity.

Title: Method and device for washing well
Inventor: NAGASHIMA FUMIO
IPC: E21B21/00
Filed: 1994-05-16
Abstract: PURPOSE:To wash the blinding materials of gravel filling all screen areas and its outsides and to enable mud walls and clay to be removed completely by installing a plurality of upper and lower water barrier plates inside a well pipe and a spray nozzle body in a sealed area between the plates, and performing washing using underground water pumped by a speed-controlled submersible motor pump. CONSTITUTION:Underground water ejected from a spray nozzle 4 is forced to pass through the screen 12 of a well pipe 14 while washing the screen. On reaching outside filling gravel 13, the underground water forms a downward flow that passes through the gravel 13. The underground water is forced to flow into the well pipe 14 again through the lower screen 12 and is sucked into a submersible water pump 1. Then a gate valve 7 and an inverter control panel 11 are controlled above the ground to control the rotation speed of the pump 1 to vary the speed of injection and the rate of flow of the nozzle 4, and blinding materials washed out by force-feeding are discharged onto the ground. Therefore, any well whose discharge is seriously decreased can be made to restore its capacity.
