Title: Image data compression device
Inventor: YAMAGUCHI TETSUYA
IPC: H03M7/30
Filed: 1994-06-27
Abstract: PURPOSE:To lower the dependence of the size of data on input image data by comparing designated size with the size of outputted data and changing quantization table data so as to reduce difference between them. CONSTITUTION:When the first compression is completed, a compressed data controller 8 compares designated size data stored in a designated size storage device 7 with compression data size stored in a compressed data storage device 6. When the compressed data size is larger than the designated size, quantization table data stored in a quantization table storage device 4 is set at a large numeric value, adversely, when the former is smaller than the latter, the quantization table data is set at a small numeric value. After that, the second encoding is applied to conversion code data stored in a conversion code data storage device 2 by a quantizer 3 and a variable length encoder 5, and compressed data is stored in the device 6. A compression operation is completed when the compressed data size nearly approaches the designated size.

Title: Semiconductor integrated circuit device
Inventor: OWADA NOBUO
IPC: G01K7/22
Filed: 1987-06-12
Abstract: PURPOSE:To prevent a resistance value of a polycrystalline silicon resistance from fluctuating due to a change in temperature and contrarily to detect the temperature, by utilizing a change in a temperature characteristic of polycrystalline silicon according to the amount of doping impurities. CONSTITUTION:A temperature characteristic of a resistance value of a polycrystalline silicon film doped with impurities depends largely on a concentration of the impurities. when the concentration is high (for example 8X10<20>/cm<3> or more), the resistance value increases as the temperature rises. when the concentration is low (for example 2X10<19>/cm<3> or less), the resistance value decreases as the temperature rises. when the concentration is middle (for example (0.7 to 2)X10<20>/cm<3>), the resistance value does not fluctuate at all according to the change in temperature. Accordingly, only selection of the amount of doping impurities can prevent the value of polycrystalline silicon resistance from fluctuating due to the change in temperature, and also the fluctuation in the resistance value can be utilized to detect the temperature.

Title: Synchronizing pattern detection circuit
Inventor: MORI TAKAAKI
IPC: G11B20/10
Filed: 1988-06-13
Abstract: PURPOSE:To attain accurate synchronizing pattern detection even while allowing a code error of a degree by adopting the constitution such that an output of a pattern coincidence detection circuit is used for an input to each OR gate and an output of an OR gate of the final stage is used as a synchronizing pattern detection output. CONSTITUTION:A data signal fed to an input terminal 1 is inputted sequentially to a shift register 10 and 16 bits of Q0-Q16 are fed to a coincidence detection circuit 11, where coincidence detection is applied. When the coincidence of any pattern in synchronizing patterns SY0-SY4 is detected correctly, a synchronizing signal pulse SY as the detection output is obtained at the output of the OR circuit 19 at the final stage from the coincidence detection circuit 11. Thus, even if any data error takes place near the start (or end) of the synchronizing pattern, any of coincidence pulses SY3-SY1 is detected correctly to obtain the synchronizing pulse SY to attain synchronization. Thus, a new synchronizing pattern detection circuit able to detect the synchronizing pulse even with a code error allowed to some degree is obtained.

Title: Data communication controller
Inventor: SUMIDA KEIZO
IPC: H04L7/00
Filed: 1987-06-11
Abstract: PURPOSE:To reduce reading operation on a transmission side as much as possible and to perform efficient data transmission by providing a memory which sends the output of a counter operating associatively with the reading/writing operation of an FIFO (First-In First-Out) memory to a transmission side at a request from the transmission side. CONSTITUTION:A CPU 2 when sending data reads in the state of the FIFO memory 4. The value of a counter 5 is latched by a memory 6 at the timing where the value of the counter 5 is determined, and the data is read in by the CPU 2 through a bus 1. The data that the CPU 2 obtains is the quantity of data which can be transmitted currently, so the CPU 2 determines whether or not transmission is performed and how many data are sent when the transmission is performed through software according to the data value in consideration of the requested quantity of data and the utilization conditions of the bus 1, thereby performing the transmission. Consequently, a read is made once to know the state of the FIFO memory on the transmission side, so the time required for the transmission can be shortened.

Abstract: PURPOSE:To form a vortex chamber to a compact shape by preventing it from becoming a large outside diameter, by dividing it into two of the upper and the lower parts. CONSTITUTION:A vortex chamber is formed to a compact shape by preventing it from becoming a large outside diameter, by dividing it into the upper and the lower parts, namely, the first vortex chamber into which a fluid flows, and the second vortex chamber 15 in which a sphere 16 rotates. In this state, the fluid is made to flow into the second vortex chamber 15 from the center of the vortex chamber, by which even if the sphere 16 is not detained, the sphere 16 is pushed to the outside periphery of the vortex chamber and rotated, therefore, due to a fact that the sphere 16 executes a rotary motion stably by an operation with a guide groove 14 of the sphere 16, and a fact that an outflow of the fluid from the peripheral part is utilized, a pressure loss of the fluid becomes smaller than the case when it flows out from only the center of the vortex chamber.
