A method for manufacturing an Al&#x2014;Mg&#x2014;Si series alloy plate includes the steps of hot-rolling and subsequently cold-rolling an Al&#x2014;Mg&#x2014;Si series alloy ingot. The Al&#x2014;Mg&#x2014;Si series alloy ingot consists of Si: 0.2 to 0.8 mass %, Mg: 0.3 to 1 mass %, Fe: 0.5 mass % or less, Cu: 0.5 mass % or less, at least one of elements selected from the group consisting of Ti: 0.1 mass % or less and B: 0.1 mass % or less and the balance being Al and inevitable impurities. Heat-treating for holding a rolled ingot at 200 to 400&#xb0; C. for 1 hour or more is performed after a completion of the hot-rolling but before a completion of the cold-rolling.

A binocular has a focusing mechanism and a convergence angle correction mechanism. Focusing is achieved by moving an objective optical system or eyepiece optical system along an optical axis. The convergence angle correction mechanism, which is interlocked with the focusing mechanism, decenters an element of the objective optical system translationally with respect to the optical axis. The translational decentering is achieved by moving the objective optical element in a direction at an angle to the optical axis.

Propylene oxide is recovered through the use of an additive in a distillation solution, resulting in suppressed side reactions and reduced loss of product. Propylene oxide is produced by oxidizing ethylbenzene in a liquid phase with molecular oxygen to a obtain a reaction liquid containing ethylbenzene hydroperoxide; distilling the reaction liquid to obtain a concentrated solution of ethylbenzene hydroperoxide; further mixing and reacting the concentrated solution with propylene to obtain a mixed solution containing propylene oxide; and distilling the mixed solution to separate and recover propylene oxide. At least one compound selected from aliphatic saturated alcohols having 2 to 4 carbon atoms, allyl alcohol, saturated aliphatic hydrocarbons having 6 or 7 carbon atoms, benzene, ethers, ketones, nitriles, amines, pyridines, diamines, and aminoalcohols is added to the mixed distillation solution in an amount of 0.01-100 parts by weight per 100 parts by weight of propylene oxide.

A focusing lens for adjusting the dioptric power in accordance with the user's dioptric power is provided in each of right and left lens barrels. When a main switch dial is set at a normal position, a microcomputer sets the focusing lens at a dioptric power of 0 by controlling a motor so that the focusing lens moves to a position corresponding to a dioptric power of 0.

Telescope having mechanism for automatically returning optical system to

In a telescope, the adjustment order is limited so that dioptric power adjustment is made after adjustment of a distance between a pair of optical systems is completed. A pupil distance and a dioptric power correction amount are stored in a memory for every user. When a user uses the telescope, his or her pupil distance and dioptric power correction amount are read out from the memory to automatically make adjustment.

A process for producing 5-vinyl-2-norbornene which comprises the steps of subjecting a liquid raw material in which tetrahydroindene/dicyclopentadiene ratio (by weight) falls within the range of from 5/100 to 80/100 to a thermal decomposition in liquid phase in the presence of an aromatic hydrocarbon solvent having a boiling point of from 250.degree. C. to 300.degree. C. at a reaction temperature of not lower than 200.degree. C. and lower than 240.degree. C. for a reaction time of from 10 minutes to 120 minutes to obtain a liquid reaction mixture (A-1) composed of 50% to 70% by weight of cyclopentadiene, distilling the liquid reaction mixture (A-1) to obtain fraction (B-1) composed of 90% to 100% by weight of cyclopentadiene and fraction (B-2) composed of 60% to 90% by weight of the total of dicyclopentadiene and tetrahydroindene, further distilling the fraction (B-2) to obtain fraction (B-3) composed of 15% to 40% by weight of dicyclopentadiene and fraction (B-4) composed of 60% to 100% by weight of tetrahydroindene, recycling the fraction (B-3) into the liquid raw material, removing the fraction (B-4) out of the system, and subjecting the fraction (B-1) to a Diels Alder reaction with butadiene to obtain a liquid reaction mixture (C-1) composed of 20% to 40% by weight of 5-vinyl-2-norbornene.

Each optical system includes an object lens and ocular lens arranged at a front part and at a rear part of the housing respectively. Further, a light admitting window is placed on the central line between the first and second optical systems for admitting light from an object. A detection module, provided independently of the first and second optical systems is used to output electrical signals which represent the distance to the object. The detection module may include an optical path deflecting means for z-shapely deflecting the light from the light admitting window and for directing the light to a sensor. The binocular is compact and has a hand grip that is designed in order to be holdable and focusable by the use of a single hand.
