IPC: B09B3/00
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a safe process for heating a carbonization chamber which prevents abnormally excessive heating of the carbonization chamber in the first half of the heat treatment, i.e., up to a predetermined time from the initiation of carbonization, and improves the durability of the apparatus. SOLUTION: A combustible organic material is roasted using a heating apparatus which heats a carbonization chamber containing the combustible organic material from its periphery. Here, for a predetermined period (t1) after the initiation of heating and from the predetermined time (t1) to the end of carbonization (t2), the heating of the carbonization chamber is conducted using a combination of a heating apparatus control system which switches on/off the heating apparatus in response to the value indicated by a thermometer placed inside the carbonization chamber and a timer which turns off the heating apparatus after a predetermined time (t1) and then restores the heating apparatus after another predetermined time (Δt). At the end of carbonization (t2), the heating apparatus is switched off by another timer and then cooled.

In this sheet 2, many lens columns are formed in parallel with one another such that the ridgeline of the lens columns has 3 to 13 degree angle against the side edge of the sheet 2. Then, by mounting the sheet 2 on the light exit surface of the body 3 such that both side edges coincide with each other, the ridgeline of the lens columns has 3 to 13 degree angle against the side edge of the body 3. Thus, the moirι phenomenon between the ridgeline of the lens columns of the sheet 2 and pitch lines among the pixels of a liquid crystal element is controlled.

Abstract: PROBLEM TO BE SOLVED: To satisfactorily enlarge the low reproduction band of a small speaker device by fixing the inner peripheral parts of first and second vibration boards different in semi-vertical angles to the outer periphery of a voice coil bobbin by detaching them in the vibration direction of the voice coil bobbin by a prescribed interval. SOLUTION: The inner peripheral parts of the first and second vibration boards 20 and 21 different in the semi-vertical angles are fixed to the outer periphery of the voice coil bobbin 6 by detaching them in the vibration direction of the voice coil bobbin 6 by the prescribed interval. The effective mass of a vibration system becomes heavy and the reproduction area of a low frequency can be accordingly enlarged. Since the effective mass of the vibration system of the speaker device becomes large, it is necessary to enlarge the permission input of the voice coil 6a. Even if the permission input is enlarged, the cross section of a connection part between the vibration boards 20 and 21 and the voice coil bobbin 6 becomes a triangular form and it becomes proof against deformation.  The vibration boards 20 and 21 are prevented from rolling and the low reproduction band of the small speaker device can satisfactorily be enlarged.

Abstract: PURPOSE:To enable zooming while maintaining an in-focus state by tracing the stored position of a focus lens back when zooming from a wide-angle side to a telephoto side is performed in manual focus mode. CONSTITUTION:A track storage means F is stored with the movement track of a focus adjusting means B during 1st power varying operation and when 2nd power varying operation is performed, a moving speed determining means G determines the moving speed of the focus adjusting means B according to the track stored in the track storage means F and the previously set movement time of the focus adjusting means B. Namely, when zooming to a telephoto direction is performed in manual focus mode, the position of a focus lens 105 which is stored at the time of zooming to a wide-angle direction is traced back to enable the zooming to the telephoto direction while maintaining the in-focus state in the manual focus mode. In this case, out-of-focus is caused owing to the difference from the position traced at the time of the zooming to the wide-angle direction, but the time is extremely short, so on out-of-focus is actually felt.
