Title: Production of isobutylene
Inventor: ARAKAWA SHINICHI
IPC: B01J21/00
Filed: 1982-11-09
Abstract: PURPOSE:To obtain isobutylene, by removing a 4C hydrocarbon mixture from crude methyl tert-butyl ether in the first distillation column, removing most of the isobutylene dimer in the second distillation column, and reacting the methyl tert-butyl ether in the presence of a solid acid catalyst. CONSTITUTION:Crude methyl tert-butyl ether is led to the first distillation column to separate a 4C hydrocarbon mixture from the top of the first distillation column, and the resultant bottom fraction is then fed to the second distillation column to give methyl tert-butyl ether containing 500ppm by weight isobutylene dimer from the top of the second distillation column. The resultant fraction is then reacted in the presence of a solid acid catalyst to afford the aimed isobutylene. One distillation column is used to separate a fraction containing the 4C hydrocarbon mixture from the top of the distillation column, and a fraction rich in the isobutylene dimer is separated in the bottom of the distillation column. Methyl tert-butyl ether containing <=5,000ppm by weight isobutylene dimer is obtained from the side stream and then fed to the reaction.

Title: Ink jet recording head
Inventor: TSUZUKI MITSUO
IPC: B41J2/14
Filed: 1987-08-07
Abstract: PURPOSE:To enable plane scan of high recording density to be performed, by a method wherein not less than two lines of liquid drop injecting fine holes are arranged uniformly at a pitch of not more than one half of a size of a heating element and, further, a gap between the heating element and the fine hole is made not more than the size of the heating element. CONSTITUTION:A nozzle board 105 on which not less than two lines of nozzle holes 14 forming an ink drop to be flown are arranged uniformly at a pitch of not more than one half of a size of a heating element 107, is used. When this nozzle board is used, a plurality of nozzle holes are arranged opposed to one heating element. Therefore, by formation of a bubble with one heating element, a plurality of ink drops are injected from a plurality of the opposed nozzle holes. Since many ink drops are injected with one heating element, though positions of the nozzle holes and the heating element are shifted, a marked variation is not generated in the number of the ink drops to be injected. That is, since it is not required that nozzle holes are accurately registered by each heating element, a line type head of a board width can be realized.

Filed: 1990-07-27
Abstract: PURPOSE:To reduce electron and hole captive levels by forming semiconductor of silicon and oxide of silicon dioxide in a metal-oxide-semiconductor capacitor and incorporating predetermined properties in the silicon dioxide. CONSTITUTION:An electron captive level in a silicon dioxide film is formed of H2O, OH, H, etc., dissolved in solid solution in SiO2. A hole collecting level is caused by a deformed Si-Si bond. In order to reduce the electron collecting level, a gate oxide film is formed in an oxidative atmosphere containing 10ppm or less of moisture content at 800 deg.C or higher. Further, in order to reduce the hole collecting level, an oxide film is formed, and then cooled from its oxidizing temperature to an room temperature in an oxidative atmosphere. For example, if a steam concentration is 0.5ppm, a hole collecting level density is set to 2.6X10<12>/cm<2>. After the oxidation was finished, it was cooled to the room temperature in 5min in an oxygen atmosphere. Then, the level density could be set to 1.0X10<12>/cm<2> of half or less.

Abstract: PURPOSE:To improve workability by connecting a liquid pipe to the upper side of the liquid sump part of a liquid sump case body which is connected to a hollow chamber, providing a partition member for preventing a vapor from entering said liquid pipe, in said liquid case body, and confining the connecting part to said hollow chamber only to its upper part. CONSTITUTION:The generated quantity of heat in a bearing 3 is transferred to a pedestal 4, and a working fluid in a hollow chamber 7 is vaporized to become a vapor and moved to a radiating device 8 as shown by the arrow A. The working fluid coagulated and liquefied in the radiating device 8 is once stored in the liquid sump part 14 of a liquid sump case body 12 via a liquid pipe 15 as shown by the arrow B, and, then, is returned to the upper side of the hollow chamber 7 via the inner wall of an overflow pipe 13, while the vapor is prevented from entering the liquid pipe 15 by means of a partition member 16. By repeating these behaviors, the generated quantity of heat in the bearing 3 is thermally transferred to the radiating device 8 to efficiently carry out cooling. The connecting part to the hollow chamber 7 of the pedestal 4 is confined only to its upper part and there is no connecting part in the place below a rotary shaft 1, simplifying the labor of the connecting operation, maintenance, etc. of the connecting part.

Title: Treatment of waste acid solution
Inventor: SATOU ISAO
IPC: C02F1/66
Filed: 1983-10-21
Abstract: PURPOSE:To bring two waste substances to a non-pollution synthetic substance without performing post-treatment of both substances, by mixing a residual solution, from which an effective acid is recovered, after the acid treatment of stainless steel and/or a waste solution after surface pickling with steel slag to neutralize both of them. CONSTITUTION:As the post-process of the acid treatment of stainless steel, a residual solution from which an effective acid is recovered and/or a waste solution after surface pickling are mixed with steel slag to neutralize both of them. By this method, an expensive alkali agent, which has been used separately, is unnecessary and the fine metal still remaining in the neutralized product can be recovered by magnetic flotation. Furthermore, because the Ca- and Mg-compounds in slag reduce Cr<6+> to Cr<3+> and subsequently allows Cr<3+> to coprecipitate, noxious Cr<6+> is not generated.

Abstract: PURPOSE:To obtain a polychromatic image which has good color reproducibility and no color mixing by repeating the operation in which the entire surface is exposed to light transmitted through one kind of filter after a photosensitive body is exposed to an image through plural color separation filter layers, development is carried out, and the residual charge in a toner sticking area to uniform the surface potential. CONSTITUTION:The photosensitive body consists of a conductive substrate 1, photoconductive layer 2, and an insulating layer 3 including color separation filters R, G, and B. The entire surface is charged positively by an electrostatic charger 4 to generate a negative induced charge in the boundary surface between the layers 2 and 3. While the surface potential is held uniform through the negative electrostatic discharging of an electrostatic charger 5, image exposure using, for example, red light LR is performed. Then, entire-surface exposure using light L1 passed through one kind of filter, e.g. blue light is performed to form a potential pattern, which is developed with yellow toner. The entire surface is charged uniformly by the electrostatic charger while the entire surface is exposed to blue light so as to erase some of charges remaining in the toner sticking area. Similarly, the entire surface exposure using G or R light and development are carried out repeatedly to obtain a polychromatic image.

Abstract: PROBLEM TO BE SOLVED: To give an operator a constant feeling of operation, regardless of a size of moment of inertia of a revolving body with respect to an axis of rotation of the revolving body, during the revolution/acceleration of a hydraulic work machine. SOLUTION: Moment of inertia I of a revolving body with respect to the axis of rotation is detected by moment of inertia detecting means 7B, 7B, etc., while the pressure P of pressure oil, which is supplied from a flow control valve 5A to an actuator 3A of the revolving body, is detected by pressure detecting means 7A, 7A.
