Title: Recording medium and picture data compression method
Inventor: SUZUOKI MASAKAZU
IPC: H04N19/436
Filed: 1991-03-04
Abstract: PURPOSE:To compress a bit number of a picture element and to attain highly efficient data compression by dividing a picture data into a small area and quantizing adaptively the picture data in response to a dynamic range of a color of a picture for each small area. CONSTITUTION:A data of one frame of an original picture is divided into a character by a character division means 22, fed to a vector quantization means 24 via a register 23, in which the data is subjected to vector quantization in a way that colors represented as a picture element are four colors or below. Then a maximum value of a quantization error of all characters in a frame is obtained, and when the value is larger than a threshold level, the data in the characters are quantized just before the error exceeds a maximum value to decrease number of colors of picture elements. Thus, the picture data compressed to be 4 colors or below is obtained from the means 24. Thus, the bit number of the picture element is selected to be a bit number in response to the color dynamic range and the data compression is implemented with a high efficiency.

Title: Semiconductor memory device
Inventor: ITOU YASUO
IPC: H01L21/3205
Filed: 1984-03-30
Abstract: PURPOSE:To shorten retardation time, to enable access operation at high speed and to improve reliability by setting the mutual positions of contacts between word lines having double layer structure at ununiform intervals so that pitches are reduced gradually toward a finishing end section from a starting end section. CONSTITUTION:A first word line 56 and a second word line 60 are brought into contact at a plurality of positions (such as eight positions) along one word line in a chip, but the arrangement of the positions of contacts along one word line is made different from conventional devices and the positions of contacts are disposed at unequal intervals. The state is shown in the figure. C11, C12...C18 represent the positions of contacts, and C11 represents the word-line driving circuit side, a starting end section, and C18 the ending end side. The wiring retardation of the whole word lines can be reduced to tau'm from taum on a comparison at the maximum retardation time by narrowing the spaces of the contacts of the finishing end section. That is, wiring retardation can be made less than double-structure word lines brought into contact at intervals the same as conventional devices without changing the number (numeral 8 in the figure) of contacts.

IPC: G21C7/26
Filed: 1990-03-14
Abstract: PURPOSE:To control a core flow rate always constant by compensating an adverse effect, even when an instant loss of electric power occurs at one of the first and the second variable frequency electric power supplies, by conducing frequency controlling of the other supply. CONSTITUTION:When switching operation between an ordinarily operated frequency controlling part and a stand-by frequency controlling part is conducted, an instant loss of electric power occurs at the first variable frequency electric power supply 6A and a detection means 103A of instant loss of power detects the loss. In the same manner, when such a switching operation is conducted to the second variable frequency electric power supply 6B, the instant loss of power is detected by the detection means 103B of instant loss of power. In case that the means 103B detects the instant loss, an accumulation means 104A of instant loss bias signal accumulates the instant loss bias signal to the first frequency demand signal, Also, in case that the means 103A detects the instant loss, an accumulation means 104B of instant loss signal accumulates the instant loss bias signal to the second frequency demand signal. After that, the variable frequency electric power supply which is fed the frequency demand signal accumulated by the instant loss bias signal, controls a motor for pump so as to increase rotation to corresponding extent accumulated by the instant loss bias signal.

Title: Semiconductor electrode substrate for liquid crystal panel drive
Inventor: KANO TOSHIO
IPC: G02F1/13
Filed: 1978-05-29
Abstract: PURPOSE: To reduce greatly the number of the lead-out terminals to outside and thus to reduce the assembling cost by incorporating the peripheral circuits into the same substrate and in nearly the same process as the picture element selecting semiconductor element.  
     CONSTITUTION: For the static drive type liquid crystal panel electrode substrate containing the semiconductor element with every picture element, not only the picture element selection part but the peripheral driving circuit are integrated onto the same substrate. Both the shift register and the converter which are the peripheral circuits feature the exactly same manufacturing process to each other since the circuit consists of the MOS-type transistor similar to the picture element selecting transistor. Thus, the semiconductor element can be manufactured in the same process along with the peripheral circuits. In such way, the peripheral circuits are integrated onto the same substrate, and as a result the number of the terminals to be connected can be reduced down to 4 or 5 pieces such as the input signal, clock and power terminals and others. Accordingly, the assembling cost can be reduced.

Abstract: PURPOSE:To prevent a wrong item generated due to the format of indication of an operator from being inputted by discriminating the inputted area of an input coordinate, and displaying the fact that an area is a specific area when it is the coordinate outside the specific area. CONSTITUTION:For example, when each item is displayed on a display means 3, the operator touches the input means 1 and designates an item so as to indicate the item. Coordinate data is added on an area discrimination means 2 by the above touch, and the area discrimination means 2 discriminates whether added coordinate data is within the area of the item set in advance or the one in an intermediate area, and when it is in the intermediate area, outputs the fact that it is the one in the intermediate area to the display means 3.
