Title: Dynamic random access memory cell having double floor structure
Inventor: NAKANO MOTO
IPC: H01L27/06
Filed: 1985-08-30
Granted: 1990-06-04
Abstract: A write selector transistor is disposed over a read select transistor (T1), the two being separated by an insulator layor and sharing a drain region. A storage transistor (T3) is formed on a silicon substrate in the same level as the read selector transistor. Channel regions (CH1, CH3) of the two transistors are connected to one another and each is used as a diffusion region of the other two transistors. Write and read select lines may be combined into a single control line or a write/read select line. Here gate electrodes of the read and write select transistors are connected to the write/ read select line and are distinguished by having different threshold voltages.

Title: Method of making the fluorescent material layer in panel of crt and device of making the same
Inventor: SAGOO SEIJI
IPC: H01J9/227
Filed: 1987-03-28
Granted: 1990-10-19
Abstract: A powder-receptie adhesive pattern (I) is formed on the inner surface of a rectangular panel having a skirt portion at the periphery. A sealed vessel consists of a container containing phosphor powder and the panel. The container and the panel are integrally combined so that the opening of both are opposd. The container is rotated about an axis parallel to the inner surface of the panel. As the sealed vessel rotates, the phosphor powder is sequentially moved while sliding on the inner surface of the side of the panel, (I) forming surface of the panel and the inner surface of the powder container. Thus, since a new adhesive surface of (I) is always exposed by a capillarity phenomenon, a powder layer is firmly formed.

Title: Buffer memory switching circuit of a stop picture phone
Inventor: LEE SANG-HUN
IPC: H04N7/14
Filed: 1992-03-18
Granted: 1995-03-24
Abstract: The buffer memory switching circuit switches image data into buffer memory and then transfer into image processing unit in order to prevent overlapping of successive screen frames. The buffer memory switching circuit comprises a receiver FIFO receiving image data; a CPU providing the control signals for the receiver FIFO; the data transceivers outputing image data; a latch; a demultiplexier; a line driver; the first buffer RAM controlled by CPU signals; the second buffer RAM controlled by an external image processing unit.

Title: Driving condition control circuit and method for vtr
Inventor: AN JIN-WON
IPC: G11B15/02
Filed: 1992-03-23
Granted: 1994-08-18
Abstract: The circuit provides a mode selection key that controls the driving status of the driving mode and decreases the number of the key matrix key. The circuit comprises: a selection key generating the corresponding signal of the video driving mode; a driving control key tuning each driving status selected by the mode selection key; a control circuit for controlling the video system by the selection mode after decoding the corresponding signal of the selection mode and detecting the current excution mode after receiving the output signal of the driver circuit.
