Filed: 1984-09-12
Abstract: PURPOSE:To produce the titled compound in high yield by the vapor-phase oxidation of 1,2-propanediol, economically in an industrial scale, without using a hardly available catalyst, by contacting 1,2-propanediol with powdery silver having specific particle diameter. CONSTITUTION:The objective compound can be produced by the vapor-phase oxidation of 1,2-propanediol with molecular oxygen in a system diluted with inert gas, in the presence of a silver catalyst having particle diameter of <=0.1mm, at 400-600 deg.C. the reaction gas is cooled as fast as possible after leaving the catalyst layer. The powdery silver having particle diameter of <=0.1mm is produced by electrolysis or by chemical means (e.g. alkali precipita tion). It can be used as it is or by adding to crystalline silver of >=0.1mm diame ter in an amount of >=5wt%. A copper mesh, etc. may be used in place of the silver particle, however, an iron-based alloy which acts as a catalyst poison is inadequate to the purpose.

Title: Disk storage device
Inventor: AOKI YUTAKA
IPC: G11B5/09
Filed: 1985-08-30
Abstract: PURPOSE:To prevent the reading errors caused by the different levels of storage density of a disk storage device by changing plural reading load resistances by means of a switch and then changing the resolution of a head resonance system in accordance with the storage density of the disk. CONSTITUTION:The switch signal is set at a level that shows a low level of storage density when a disk of a low storage density level is used. Then a switch 23 is turned on and therefore a load resistance 22 is short-circuited. Thus the resistance value of the reading load resistance of a signal processing mechanism is set at R1. When said resistance value is reduced, the damping constant eta is increased. Then the frequency characteristics of a head resonance system has a drop at its high band. Thus the resolution can be reduced. The resistance values R1 and R2 of both reading load resistances 21 and 22 are set in response to the dtorage density of the disk. These resistance values are changed by the switch 23. Thus it is possible to prevent the malfunction of a ZCC without switching an LPF or differentiating circuit.
