Title: Automatic paper feeder
Inventor: MARTIN JYAI PAJIETSUTO
IPC: B65H3/50
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To provide the automatic paper feeder which minimizes the deviation of the tip end periphery of the medium from the first line of printing by means of a kicker device compact in structure, and inexpensive in price. SOLUTION: Since the automatic paper feeder comprises take-out tires mounted on the shaft for selectively moving the sheet shaped medium out of a stacked body, a kicker 76 holding the medium over the stacked body at a fist position, and a cam mounted on the shaft for biasing the kicker 76 from the first position to a second position, the cam 72 is engaged with the medium over the stacked body during the period of a part of a rotation cycle, and furthermore the kicker 76 is pushed out to the second position so as to enable the medium to be brought into contact with the respective take-out tires. Furthermore the couterclockwise rotation is kept on, after one sheet of the medium has completely passed through the kicker 76, it is made possible that whole of the medium remaining over a separation pad 82 can thereby be pushed back to the stacked body by the restoring force of the kicker 76 to an original position.

Title: Cleaning method for semiconductor
Inventor: WATANABE MASAHIRO
IPC: H01L21/304
Filed: 1990-09-19
Abstract: PURPOSE:To prevent a stain at a drying process by a method wherein an extremely thin oxide film is formed on the surface of an object to be cleaned at a cleaning process or the drying process, the surface of a semiconductor is irradiated with ultraviolet rays in an atmosphere containing oxygen or ozone before the cleaning process and a thin oxide film of a substance is formed on the surface of the semiconductor. CONSTITUTION:Before a cleaning process 2, in a narrow sense, which removes a contamination, a treatment 1 to form a stable oxide film on the surface of an object to be cleaned is executed. Thereby, even when a drop of water is left on the surface of the object to be cleaned at a drying treatment, it is possible to prevent the formation reaction of an oxide which is easily dissolved in water and to prevent a dry stain from being produced. When a treatment 4 to irradiate ultraviolet rays in an atmosphere containing ozone or oxygen is executed in advance, a stable oxide film is formed on the surface and it is possible to prevent a stain from being produced through a subsequent cleaning treatment 5 and a subsequent drying treatment 6.

Title: Compression system for image two dimensional dither information
Inventor: YAMAZAKI NOBUHISA
IPC: H04N1/41
Filed: 1983-12-29
Abstract: PURPOSE:To permit a symbol line to be efficiently compressed by comparing variable density of each lattice point contained in picture surface submatrix with slice levels to prepare a symbol line. CONSTITUTION:The system adds picture signals to a comparator 1-i (i=0, 1, 2... 7) and outputs logic 0 when a picture level is greater than a level i, and also outputs logic 1 when the picture is smaller than the level i. A changeover switch 2 selects either one of a comparator 1-0 or a comparator 1-7 according to the last two bits in a bit counter which indicate an X direction position and the last one bit in a laster counter which denotes a Y direction position, and writes said bits in a memory 4. The system reads out the symbol lines of submatrix in order from the memory 4, and counts the number of logic 1 by a counter 5. The system compares the numbers with a forecasting pattern by a forecasting coincident detector 6, and when the numbers are coincident, the system leaves the counter values as they are but sends corrected values to an information extension side when the numbers are not coincident.

IPC: G06F12/00
Filed: 1988-09-30
Abstract: PURPOSE:To shorten the information retrieving time and the updating time of an index file together with reduction of the memory size and the capacity of a work file by using a storage device containing an index file and a retrieving device. CONSTITUTION:An input device 1 inputs subject data for retrieval of the information via a terminal, a file, etc., and decides the type of the data from its contents. Then the device 1 stores successively the data into a data file 21 of a memory 2 and at the same time extracts the key words to store them into a key word file. These key words are sorted in the order of codes for production of a data type-based index file 22 together with preparation of a higher level index file 23 which shows a specific data type to which the key word designated in a retrieval formula is related. Then a retrieving device 3 inputs a retrieving formula showing the retrieval concept via a terminal or a file and converts the formula into an internal form. Then the device 3 has an access to the memory 2 to prepare the list of data types and their numbers as an answer of retrieval. Thus the information retrieving time and the index file updating time can be shortened together with reduction of the memory size, etc.
