Title: Separation and purification of 5-acetamide-2-nitrophenol and 3-acetamide-4-nitrophenol
Inventor: OGATA HIROSHI
IPC: C07C67/00
Filed: 1986-07-14
Abstract: PURPOSE:A mixture of 5A-2NP and 3A-4NP is separated into individual compounds in the form of an alkali metal salt to readily give, in high efficiency, the compounds which are used as synthetic intermediates of a water-soluble synthetic substrate for determination of enzyme activity and of reagents for analysis pentenol. CONSTITUTION:A mixture of 5-Acetamide-2-nitrophenol (abbreviated to 5A-2NP) with 3-acetamide-4-nitrophenol (3A-4NP) is converted into alkali metal salts of individual compounds using an alkali metal alcoholate such as sodium methylate. The sodium salt of 5A-2NP is hard soluble in methanol, while the 3A-4NP salt is readily soluble. The difference in solubility is utilized to separate one isomer from the other. The mixture of 5A-2NP with 3A-4NP is obtained by nitration of 3-acetamidephenol with a nitrating reagent such as conc. nitric acid-acetic anhydride at 10-40 deg.C.

Door key 4 is pivoted on pin 11 inside of door 2 freely rotatably and activated downward by spring 12. Key 4 pushed up by lever 10 moves beyond door hook 6, slides down on an inclination part and pushes out door 2 to the front, opening the door. Microphone 7 for voice input is fixed with the maximum directional sensitivity directed to the side of the front heater face, so that the danger that the door 2 collides with the operator during the door opening operation can be prevented.

Title: Low pressure rare gas discharge lamp
Inventor: NISHIKATSU TAKEO
IPC: H01J17/20
Filed: 1981-10-20
Abstract: PURPOSE:To obtain a low pressure neon discharge lamp that can mainly obtain emission of neon by containing a small amount of argon. CONSTITUTION:In a discharge container that seals the mixed gas of neon and argon, supposing that the sealing pressure of the mixed gas is P (Torr) and the argon mixing ratio is A(%), a relationship of A<=5P<-2>(%) is satisfied. As a result, since the mixed gas of argon and neon is used, the discharge start voltage  can be reduced by Penning's effect. For example, for the pressure of 5Torr, while the discharge start voltage of a lamp that seals a single body of neon is approximately 135V, that of a lamp of argon mixing ratio of 0.1% is reduced to approximately 105V.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of breaking by monitoring the sliding of a water shielding sheet into an excavated hole. SOLUTION: In a construction method of a water shielding sheet 2 where a water shielding sheet 2 is constructed so as to form an inner wall of an excavated hole 1 and its extended area 2A is fixedly supported on a ground, the end of the extended area 2A is fixed on the ground, thereby constructing the extended area along the inner bottom formed on the ground and forming a loosened area 2C.

Title: Method and apparatus for tracking-type optical wireless communication
Inventor: NAITO SHINJI
IPC: H04B10/11
Filed: 1992-06-25
Abstract: PURPOSE:To automatically adjust an axis shift and easily search for a communication target as well as communicate more information irrespective of adverse influence or the like of external noise. CONSTITUTION:Since diffusion light 14, 15 is emitted to each other at the time of searching for communication targets, a wider searching range at the time of emission than a case where condensed light is used can be obtained to facilitate searching. In addition since a light transmitting/receiving part rotates in horizontal and elevation angle directions, searching can be done easily and securely even if there is difference in height between both communicators. If communication is performed with condensed light 13, transmission/reception with high frequency signals is possible, a loss due to light diffusion can be further reduced, and also adverse influence of external noise can be prevented, thereby enabling communication of much data.
