Title: Seat reclining device
Inventor: HIBINO KEIICHI
IPC: A47C1/025
Filed: 1989-09-27
Abstract: PURPOSE:To surely perform a returning operation to a memory position in a simple constitution by regulating the engagement of a pole with a ratchet by the second regulating member disposed on the other side reclining mechanism and operating the second regulating member by an operation member disposed between a connecting mechanism and the second regulating member. CONSTITUTION:A pole 32 of the other side reclining mechanism is retained by the second regulating member 57 during the forward tilting condition and during the time of returning of a seat back 4 from the forward tilting condition to the normal condition to regulate the engagement between the other side pole 32 and a ratchet 31, which are engaged by an operation member 52 after one side pole 10 and a ratchet 9 are engaged with each other. By this arrangement, the other side pole 32 is prevented from being engaged with the ratchet outside the memory position, so that the reliable returning operation to a memory position can be ensured in a constitution where a memory mechanism is disposed only on one side reclining mechanism.

Title: Wafer cleaning device
Inventor: KAWAURA HIROSHI
IPC: H01L21/304
Filed: 1984-11-30
Abstract: PURPOSE:To prevent an insulating film formed on a wafer from breaking in its insulator by filling ionized gas in an area formed between the wafer and a nozzle cover, thereby electrically neutralizing static change of pure water charged in case of injecting from a nozzle tube. CONSTITUTION:Pure water supplied from a pure water line 6 is injected as a jig from a nozzle tube 5. At this time, air or nitrogen ionized, for example, from an ionized gas supply line 8 is supplied through an ionizing gas inlet 9 into an area formed of a cover 4 and a wafer 1. Thus, when the pure water charged by static charge by vigorous friction passes the area, the static charge is neutralized to prevent the charge on the wafer 1 from storing.

Title: Resist application device
Inventor: KURIHARA MASAHIRO
IPC: G03F7/16
Filed: 1994-10-18
Abstract: PURPOSE: To form a uniform resist film thickness even immediately after washing a coating cup. CONSTITUTION: After the washing of a coating cup 4 is completed, a control part 10 measures the concentration of organic solvent where the inside of the coating cup 4 is vaporized by a concentration sensor 9 immediately before applying resist. A setting value is inputted to the control part 10 in advance, standby is made until the concentration of organic solvent is equal to the setting value when the concentration of organic solvent is larger than the setting value and resist is applied when the concentration becomes equal to the setting value. Also, when the concentration of organic solvent is equal to the setting value, no standby is made and resist is applied. On the other hand, when the concentration of organic solvent is smaller than the setting value, a valve controller 7 is opened, a washing liquid is allowed to flow out of a washing liquid outlet 5 for increasing the concentration of organic solvent. When the concentration becomes equal to the setting level, the control part 10 closes the valve controller 7 and stops the supply of the washing liquid and then applies resist. These controls are performed until the coating cup 4 is washed next time.

Title: Method for purifying 1,6-hexanediol
Inventor: YOSHIFUKU NORISUKE
IPC: C07C29/80
Filed: 1989-09-29
Abstract: PURPOSE:To obtain the subject high-purity substance by oxidizing, esterifying and then hydrogenerating cyclohexane, removing low- and high-boiling substances from the resultant reaction solution, saponifying the prepared reaction solution with an alkali and subsequently passing the saponification product through a stripper column, evaporation column and rectifying column. CONSTITUTION:Cyclohexane is oxidized, esterified with alcohols and then hydrogenated to provide a reaction solution, which is subsequently passed through the first distillation column 1 and the second distillation column 2 to remove low- and high-boiling substances. Crude 1,6-hexanediol having 10-100mgKOH/g ester value is obtained from the column top of the second distillation column. The resultant crude 1,6-hexanediol, together with an aqueous solution of an alkali, is then fed to a saponification column 4 and the prepared saponification solution is led to a stripper column 5. The bottom product is subsequently fed to an evaporation column 6 to afford 1,6-hexanediol having <=5mgKOH/g ester value while removing high-boiling substances from the bottom thereof. The obtained 1,6-hexanediol is subsequently led to a rectifying column 8 to provide the objective high-purity substance from the intermediated tray. Thereby, hardly separable esterification products can be readily removed by the distrillation of the hydrogenating reaction solution.
