Title: Cleaning method for waste water produced by aldol reaction
Inventor: MARIORA RETSUTSUHAIMU
IPC: C02F1/26
Filed: 1994-06-23
Abstract: PURPOSE: To effectively reduce the concn. of org. contaminants in waste water resulting from aldol formation reaction by adjusting the waste-water to a specified pH, separating the floating org. phase and treating the waste water by extraction with a specified monoalcohol and/or a specified hydrocarbon.  
     CONSTITUTION: When waste water resulting from the conversion of the same aldehyde or ketone, different aldehydes or ketones or an aldehyde-ketone mixture into aldol is clarified, it is adjusted to pH 0-6 and a floating org. phase is optionally separated. The waste water is then treated by extraction with a monoalcohol having ≥8C, particularly 8-16 carbon atoms in the molecule, e.g. 2-ethylhexanol or 3,5,5-trimethylhexanol and/or a hydrocarbon having ≥6C, particularly 6-12 carbon atoms in the molecule, e.g. light fuel oil.

Title: Battery type fastening tool with forced stopping mechanism
Inventor: SUGIURA MASATOSHI
IPC: B25B21/00
Filed: 1993-06-14
Abstract: PURPOSE:To prevent any fastening failure from occurring as fastening work is performed in a state that an amount of residual capacity in a battery is in short supply, and further to stop a motor even in time of overloading, in a battery type fastening tool. CONSTITUTION:When a signal corresponding to an amount of residual capacity in a battery is detected and this residual capacity is in short supply, a switching element FET to be connected in space between a battery BP and a motor M is forcedly turned to OFF. In addition, it is turned off even in time of overloading. Therefore, when the residual capacity is insufficient, the switching element is forcedly turned to OFF, whereby even if an operating switch is turned off, the motor is not rotated at all. Likewise, the motor M will not rotate even in time of being overloaded.

Filed: 1983-08-03
Abstract: PURPOSE:To attain a hierarchical logic circuit diagram which is easily read by performing the cross reference for inscription of connection with the logical inscription of a higher level black box left as it is and discriminating the cross reference from the reference of logical inscription. CONSTITUTION:The connection cross reference of 009E60D/line A written to a pin 04 of a logic frame A3 (intra-page frame discrimination mark) shown that the pin 04 is connected to a pin 0D of a logic frame E6 in a page 009 and the signal name is equal to line A. While the connection cross reference of 009A304/ line A written to the pin 0D of the undeveloped frame E6 shows that the pin 0D is connected to the pin 04 of the frame A3 and the signal name is equal to line A. In such a way, the information on a higher level logic obtained before development is left on a hierarchical logic circuit diagram of a higher level after development. Thus the logic follow-up is facilitated and no reference is needed to the diagram before development. This attains the reduction of document quantity.

Title: Static breaking agent
Inventor: TAKAMIYA YOUICHI
IPC: C09K3/00
Filed: 1982-08-17
Abstract: PURPOSE:To provide a static breaking agent consisting mainly of CaO and containing reactive metal powder, which shortens the time necessary to start breaking and makes it possible to control breaking starting time, hydration and swelling rates, etc. by varying the amount of the metal powder. CONSTITUTION:The static breaking agent for rock, concrete, etc. consists mainly of CaO and contains reactive metal powder (e.g. Al or Fe). Currently available CaO-based breaking agents have advantages that they are silent and cause no scattering of fragments but have demerits in that they have low breaking strength, the hydration time is affected by environmental conditions leading to inconsistent breaking time and difficulty in setting up operation program, breaking does not occur at times and bumping tends to occur. Addition of the reactive metal powder shorten the time necessary to start the breaking and the breaking starting time, the rates of hydration and swelling, etc. can be readily controlled by varying the amount of the metal powder added and the thickness of a metal powder coating layer.

Title: Combustion device
Inventor: HORIKOSHI TADAO
IPC: F24C15/24
Filed: 1988-06-09
Abstract: PURPOSE:To enable the feed of secondary air to the central part of flame by a method wherein the burner port of a burner head to burn fuel-air premixture of gaseous fuel and combustion primary air is formed approximately in a U-shape. CONSTITUTION:Gaseous fuel is premixed in a vaporizing mixing chamber 13 with primary air by means of an agitating plate 14, and injected for ignition through small circular holes 23 of a burner port part 24 of a burner head 22 after the passage of it through a throttle port 18 and through-holes 20. Flame F is formed above a burner port part 24 for blue flame combustion. Since the burner port part 24 of the burner head 22 is formed approximately in a U-shape, flame F extending in a cylindrical shape toward above is formed to the burner port part 24, and a non-flame space X having a specified width is formed to a part of a peripheral direction. Since the central part of the flame F is brought into a negative pressure state through a draft action occasioned by the rise of combustion gas, secondary air is sucked and fed to the central part of the flame F from the non0flame space X. Thus, secondary air can be fed to the central part of the flame through natural ventilation produced by the draft action of the flame F, and the generation of CO can be suppressed as the generation of combustion noise is reduced.
