Title: Production of 4-aminomethyl-1,8-diaminooctane
Inventor: YAMATAKA KAZUNORI
IPC: C07C67/00
Filed: 1986-05-20
Abstract: PURPOSE:To obtain a compound useful as an epoxy curing agent, rust preventing agent, etc., in good yield while preventing deterioration of a catalyst, by purifying and separating 1,3,6-tricyanohexane (TCH) obtained together with adiponitrile by electrolytic reduction of acrylonitrile from an electrolyte and catalytically hydrogenating the TCH. CONSTITUTION:Acrylonitrile is electrolytically reduced in the presence of a quaternary ammonium salt to give an electrolyte containing adiponitrile and 1,3,6-tricyanohexane (abbreviated to TCH). The adiponitrile is then removed from the electrolyte to give <=2wt% content thereof and afford a high-boiling residue containing the TCH. The high-boiling residue containing the adiponitrile in a low concentration is subjected to molecular distillation to evaporate the TCH, which is then hydrogenated in the liquid phase in the presence of Raney nickel catalyst, e.g. raney cobalt, to afford the aimed substance.

Title: Air conditioner
Inventor: KAWAUCHI NOBORU
IPC: F24F11/04
Filed: 1983-06-24
Abstract: PURPOSE:To improve comfortability by a constitution wherein the flow rate of a blower is controlled by comparing the indoor noise with a set back ground noise by means of a microphone arranged within the indoor unit of a room air conditioner or the like. CONSTITUTION:A microphone 1c (not shown in fig) is contained within an indoor unit. The microphone 1c inputs an indoor back ground noise (e) measured during the period of standstill of an indoor blower to a comparator. When the back ground noise, the air flow rate of the blower is set at an intermediate rate M (not shown in fig.) lowered by one rank. On the contrary, when the peak value of measured back ground noise (e) exceeds the set value (f) of back ground noise, the air flow rate of the blower is set at an intermediate rate raised by one rank. Above-mentioned setting of the air flow rate of the blower is repeated during the stop-and-start cycles of operation. When the room temperature (g) exceeds the set value (h), the air flow rate of the blower is set at the intermediate rate raised by one rank regardless of the value of the back ground noise. Thus, the noise is suppressed and consequently the comfortability can be improved.

Title: Information recorder
Inventor: MATSUMURA SUSUMU
IPC: G11B20/10
Filed: 1988-05-11
Abstract: PURPOSE:To prevent an illegal use and to enable a backup copy on the other hand by providing a 1st recording medium recorded with fundamental information by a magnetic recording means and a 2nd recording medium recorded with additive information by such a means that it is difficult to copy this information by a reproducing means for the 1st recording medium. CONSTITUTION:The effective information is only constituted by combining the fundamental information and the additive information which are recorded dispersedly to the 1st recording medium 1 and the 2nd recording medium 2. Then, since the 2nd recording medium 2 cannot be reproduced by the means for reproducing the 1st recording medium 1, it is difficult to copy the additive information. In addition, the fundamental information recorded on the 1st recording medium 1 is reproducible by the magnetic recording means, so that the fundamental information can be protected against a flaw, etc., of the 1st recording medium 1 by making a backup copy of this fundamental information. By this method, a certain backup copy is feasible, but the illegal use can thus be prevented.
