Title: Method for constructing ditch and construction machine therefor
Inventor: SHIMIZU KIYOSHI
IPC: E02B11/00
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To form a ditch easily in a short time without causing environmental problems and to enable final preparation of the surface of the ground. SOLUTION: As a construction machine is made to travel to form a ditch 9 continuously using a ditch digging cutter 5, the earth to be discharged is discharged to a predetermined side by rotation of the ditch digging cutter 5 and received by a previously laid earth receiver 21, and the ditch 9 is first backfilled to a predetermined depth using stones of plural kinds of sizes from large-diameter ones including, if any, those which are being discharged, to single ones such as small-diameter stones. If stones are present in the earth discharged, the backfilling is completed with the discharged earth from which the stones have been removed, to form the backfilled part as a drainage ditch. The top of the ground dug is filled with the surplus part of the discharged earth from which the stones have been removed, thus finishing the construction work.

Title: Improvement of insulating film and manufacture of semi conductor device
Inventor: HOSOYA KOJI
IPC: H01L27/108
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To improve an insulating property of an oxide insulating film at a relatively low temperature and within a relatively short time, by effecting a process in which a heat treatment in an atmosphere of O3 (ozone) and a UV/O3 heat treatment are combined. SOLUTION: An O3 heat treatment involves the step of causing active oxygen produced by the thermal decomposition (300 to 500 deg.C) of ozone (O3 ) to penetrate into a film so as to embed oxygen defects with the active oxygen. An UV/O3 heat treatment involves the steps of: injecting ultraviolet rays in an atmosphere of highly concentrated ozone so as to decompose the ozone and obtain active oxygen whose activity is higher than that obtained by the thermal decomposition; and recovering oxygen defects with the active oxygen. The problem that the insulating property obtained by the O3 heat treatment due to an imperfect removal of impurities in the O3 heat treatment can be overcome by effecting the UV/O3 heat treatment. Further, the process time of the UV/O3 heat treatment can be shortened by effecting the O3 heat treatment.  As a result, when both treatments are combined, the process time can be reduced by about 1/3 to 1/10 that required for a single process.

Title: Electrostatic charger for color developer
Inventor: KAGAYAMA SHIGERU
IPC: G03D13/00
Filed: 1990-10-08
Abstract: PURPOSE:To provide the electrostatic charger for a color developer which does not generate ozone, etc., by bringing a charging roller impressed with a voltage into contact with the color developer carried on a carrying roller, thereby impressing the uniform and sufficient charge to the color developer. CONSTITUTION:The color developer 3 is rubbed between a supply roller 30 and the carrying roller 10 and the triboelectrostatically charged color developer 3 is carried on the surface of the carrying roller 10 and is transported. The color developer 3 carried on the carrying roller 10 and transported by this roller comes into contact with the charging roller 20. Since the negative voltage is held impressed to the charging roller 20 at this time, a slight discharge is generated between the charging roller 20 and the grounded carrying roller 10. The discharge ions generated by this discharge are attracted to the color developer 3. Consequently, the color developr 3 is charged sufficiently to the satd. electrostatic charge quantity and forms the particles charged to a uniform negative polarity. This electrostatic charge quantity is unequivocally determined by the surface area on which the discharge ions can be attracted and, therefore, the charge stability and electrostatic charge quantity are superior to a so-called triboelectrostatic charge method.

Title: Alignment method
Inventor: HARIMA YOSHIYUKI
IPC: H01L21/22
Filed: 1990-10-09
Abstract: PURPOSE:To enable the alignment by the reference surface of an aligned body whose one end only is precisely set up by machining steps to be made easily and accurately by a method wherein the thrust by the alignment member on the reference surface side of an alignment object is set up larger than the thrust on the other end side. CONSTITUTION:The thrust of an air cylinder 3 on the reference surface 1a side is set up larger by specifying the air pressure fed to the air cylinder 3 on the reference surface 1a side to be 5Kg/cm<2>, i.e., larger than the air pressure of 3Kg/cm<2> fed to the other air cylinder 4. At this time, since the thrust of the air cylinder 4 is set up smaller than the thrust of the air cylinder 3 on the reference substrate 1a side, even if the distance (l) between the ends 1a and 1b is machined longer or shorter within the specific range of allowable error, the alignment of the reference surface 1a does not get out of order. Furthermore, even if the parallelism between the other end 1b and the reference surface 1a gets out of order, a wafer boat 1 can be aligned with the specific position since the central part of an alignment member 9 is fitted to the end of this air cylinder 4 rockingly movably.
