Inventor: SHINOHARA NORIO
IPC: C07F7/18
Filed: 1987-02-05
Abstract: PURPOSE:To obtain the titled compound useful for a low toxic silylating agent in high purity and yield at a low cost, by heating N-trimethylsilylacetamide and collecting a distillate of a generated N,O-bis(trimethylsilyl)acetamide. CONSTITUTION:N-Trimethylsilylacetamide is heated preferably at 120-150 deg.C and generated N,O-bis(trimethylsilyl)acetamide is distilled preferably under reduced pressure (normally 20-200mmHg) and collected.

Title: Direct sunlight identifying apparatus, lighting controller using apparatus thereof and blind opening and closing device
Inventor: SHIKAKURA TOMOAKI
IPC: G01J1/02
Filed: 1993-02-12
Abstract: PURPOSE:To identity whether the sun is shining or not positively by applying the direct sunlight emitted from the sun on a photodetector, measuring the sunlight, cutting off the direct sunlight, measuring the skylight with the photodetector, and comparing both measured values. CONSTITUTION:At first, a light shielding band 15 of an optical sensor 11 is turned and displaced and inclined to the north side. Then, the band 15 is deviated from the path of the direct sunlight connecting the sun and a photodetector 13. Therefore, the direct sunlight is transmitted through a transparent cover 14 and reaches the photodetector 13. At the same time, the skylight from a region other than the band 15 reaches the photodetector 13. The signal corresponding to the amount of the received light is outputted. When the band 15 is inclined to the south side, the band 15 cuts off the direct sunlight. Therefore, the photodetector 13 receives the skylight from the region other than the band 15 and outputs the signal corresponding to the amount of the light. In a comparator 21 of a controller 20, these two signals are compared. A discriminator 22 judges whether the sunlight is emitted or not based on the difference in both signals. The operating command is imparted to the light adjusting device of a lighting device and a blind opening/closing device from an instructing device 23.

Title: Drying apparatus for radioactive solid waste and processing method thereof
Inventor: KOMATSU MASAHIKO
IPC: G21F9/30
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a drying apparatus equipped with a heating means for the purpose of drying which shows superior volume-reducing efficiency and stabilizing performance for a radioactive solid waste from drying to compressing stages and has high reliability. SOLUTION: A heating jacket 5 using heating steam is outfitted to a drying container 2 of a drying apparatus 1. A turntable 6 is set at a bottom part. A lid-fitting device 9 is installed at a top lid 4 to shut a waste-processing container 8 loaded on the turntable 6 and filled with a radioactive solid waste 10. Moreover, a welding torch 7 is set at an inner wall of the drying container 2 to weld a joint part between the processing container 8 and a shutting lid 8a. While the processing container 8 is rotated on the turntable 6, the processing container 8 and the shutting lid 8a in vacuum can be welded by the welding torch 7 and tightly sealed. Therefore, it becomes unnecessary to transfer the radioactive solid waste 10 to a compressing sealing container or vacuumize a vacuum container for tightly sealing the waste.  The heating jacket 5 is not disconnected, unlike an electric heater, because of the use of heating steam.

This control action is repeated at a predetermined sampling cycle, thereby an economical operation can be performed as a whole.

Title: Electrophotographic process
Inventor: TAKEUCHI AKIHIKO
IPC: G03G21/00
Filed: 1984-02-13
Abstract: PURPOSE:To relieve the exposure history of an amorphous Si photosensitive body when a semiconductor laser for near infrared light is used as a light source and obtain endurance to repetitive use by using light consisting principally of long-wavelength light of >=600 and <=800nm in wavelength as discharging light for history erasure. CONSTITUTION:An exposure history by laser light is not erased with destaticizing by electrostatic charge, which is utilized basically to narrow down the subject to exposure destaticizing; and there is some difference in the effect of ghost erasure with the wavelength and position of the exposure destaticizing, so this is utilized. The lower limit of the wavelength of pre-exposure is about 600nm and the upper limit is evident from drum sensitivity, but nearly the same effect with light of 700nm is obtained nearly up to the laser wavelength and the effect of ghost erasure is obtained up to 800nm. The sensitivity of the photosensitive body is extremely small to long wavelength light of >=800nm and the ability in destaticizing itself is lost before the ghost erasure, so that independent use provides no effect. Namely, pre-exposure with 600-800nm wavelength is optimum.

On the other hand, when signal CF is held at ''0'', circuit 5 outputs signal IT at the leading edge of external operation start signal ST. Circuit 6 stores the input operation contents indication signals and performs the operation that corresponds to the operation contents indication signals until signal ST is inputted again.
