A plastic molding apparatus and method employs a pair of dies having at least one cavity with a mirror surface and wherein a plastic base material which is pre-molded is inserted into the cavity and clamped by the pair of dies. The plastic base material is then heated and melted at glass transition temperature or higher so that a resin internal pressure is generated, and then the plastic base material is annealed so that the mirror surface is transferred to the plastic base material. One of the dies has a separation die in which the cavity is formed. A cavity forming portion thereof has a cavity forming surface and a cavity side board portion which is adjacent to the cavity forming portion and surrounds the cavity forming surface. A separating die clamping structure clamps the separation die from both sides so as to compress an elastic member mounted between the cavity forming portion and the cavity side board. When the clamping pressure is released, the cavity forming portion and the cavity side board portion separate due to a resiliency of the elastic member. An engagement portion is formed at both edge portions of the cavity forming portion which contacts the cavity side board portion so as to engage with the plastic base material and control the release of the molded plastic from the dies.

An ATF error signal is formed from a reproduction RF signal and supplied to an ATF discriminating unit 4 through an A/D converter by an ATF error arithmetic operation unit 1. The presence or absence of an ATF component is discriminated and supplied to a clog discrimination processing unit 5 by the ATF discriminating unit 4. The ATF discrimination processing unit 5 determines that a head clog has occurred in the case where the ATF component exists and the RF signal which is supplied from an RF discriminating unit 9 doesn't exist. A head cleaning is executed by controlling a loading motor 16 by a motor driver 14 on the basis of a cleaning process control 11 and making a head cleaning mechanism 17 operative.

In an aging device used to manufacture a plastic molded product, injecting and aging processes are separated from each other. Namely, a plastic base material is approximately processed in advance in a final shape by injection molding. Thereafter, the plastic base material is inserted into an aging die having plural cavities and attached to a press machine such that the aging die is clamped and opened. Next, the plastic base material is heated and melted until a temperature equal to or higher than a glass transition point so as to generate an internal resin pressure. Next, the plastic base material is gradually cooled to transfer a mirror face thereto. The aging device has a die cooling device having plural heat pipes for cooling the die and has a die heating device having plural heaters for heating the die. The heat pipes and the heaters are arranged in a die plate of the press machine. In this aging device, the aging die can be uniformly and rapidly heated and cooled and a cooling speed of the aging die can be easily controlled.

According to the method for preparing chitosan of the present invention, chitosan is prepared by inoculating a filamentous fungi belonging to the family Mucoraceae into a culture medium for pre-cultivation containing yeast extract, malt extract, peptone, glucose and magnesium sulfate to perform pre-cultivation and then inoculating the pre-culture into a culture medium for main-cultivation having a composition essentially identical to that of the medium for pre-cultivation to perform the main-cultivation. Particularly preferred filamentous fungi belonging to the family Mucoraceae is Absidia coerulea. According to the method for preparing chitosan through the cultivation of microorganisms, chitosan exhibiting uniform quality can efficiently be produced and the method does not adversely affect the circumferential environment.

A microlens array includes N lenses ranging from a 1st lens to an Nth lens and a lens arrangement area. N is a positive integer. The lens arrangement area has the N lenses arranged in array. The lens arrangement area receives light emitted from a light source. An ith (i being 1st to Nth) lens satisfies a conditional expression below: −20°≦θ≦20° where θ denotes an angle formed by a main-axis orientation of double refraction and a reference orientation.
