Abstract: PURPOSE: A wafer carrying boat is provided to minimize a contact area between a wafer edge and a slot. CONSTITUTION: A boat(300) carrying many wafers to a vertical diffusion furnace is made of quartz material. A boat includes an upper plate(310), a lower plate(320), and three or four vertical rods(330). A vertical rod held by upper and lower plates has many slots(34 0) holding a wafer edge. A wafer contact area(341) of a slot is formed to a concave or slant shape so a contact area between a wafer edge and a slot is minimized. An inlet position of a slant shape is higher than an end part. If a contact area is minimized such as a point, it also prevents a surface layer of wafer falling apart when ejecting a wafer from a slot.

Abstract: PURPOSE: A decoding device of caption/audio information is provided to receive and process caption/audio signals while displaying the caption information and playing sounds, also to store the signals on a memory, so that the stored signals can be repetitively played. CONSTITUTION: The decoding device of caption/audio information receives video/audio signals which are processed and displayed/played respectively while being discretely stored on a first and a second storage(14,18). Consequently, after releasing connection between the decoding device and a device(10) generating signals, information stored in the storages is read to be played according to an instruction via a key inputting part(15). As generating parallax between information of the both storages leads to be inconsistent with caption-displaying and audio-playing, a controller synthesizes to store a sync control signal when storing information of caption/audio on discrete memories. Therefore, the stored information is played in reference to the sync control signal, so that the inconsistence between caption-audio can be prevented. Also, a sound speed controlling function is added, which helps foreign languages to be played slowly. Therefore, in a state of storing information, the decoding device can play state information without connection with information source, to design to be handheld.

Abstract: PURPOSE: A method for controlling a pan/tilt camera is provided so that software processing speed and a camera rotation speed can be improved by virtually dividing a screen at predetermined intervals, detecting an object position by coordinates of the divided screens, and moving the camera. CONSTITUTION: A rotation direction and movement of a camera are calculated by using a screen center position of the camera and a center position of an object. The camera is moved according to a previously-set rotation speed and the calculated rotation direction and movement, by driving a pan motor and a tilt motor by a timer interrupt at predetermined intervals. Here, in order to control the motors, the peripheral devices and variables are initialized, and an external command is received and interpreted. When a direct direction conversion command is received, a rotation step number of the pan motor and a rotation step number of the tilt motor are set up by using the current screen center position of the camera and the center position of the object, thus rotating each motor. When a motor speed control command is received, the rotation speed of the pan motor and the rotation speed of the tilt motor have newly-inputted values, thus controlling the rotation speed of each motor. Accordingly, the camera is directly moved by detecting the position of the object. As a result, it is much easier to track the object and process software.
