Title: Variable length data communication system
Inventor: NAGAO KATSUYUKI
IPC: G06F13/32
Filed: 1988-08-10
Abstract: PURPOSE:To complete DMA transfer, and to eliminate the occurrence of an error even when transfer data is of variable length different from set data word length by initializing a DMAC and a transfer origin circuit, and processing received data in the case of forced stoppage, and setting the data word length newly in the DMAC in the case when received data word length reaches data word length. CONSTITUTION:When the received data word length is shorter than the set data word length of the (Direct Memory Access) DMA controller (DMAC) 42, the DMAC 42 is stopped forcedly at the finish of the received data, and immediately, received data processing by the CPU is performed. On the other hand, in the case when the received data word length is longer than the set data word length of the DMAC 42, when it reaches the data length, the state of a forced stopping means 43 is checked by interruption from the DMAC 42, and after confirming that the received data is not yet finished, new data word length is set in the DMAC 42. Thus, the received data can be surely received up to the finish of the data without being lost.

Title: Polyphenol composition
Inventor: SUGIURA KAZUHIKO
IPC: A23L1/30
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain a polyphenol composition maintaining its inherent physiological functions and improved in specific bitterness and astringency by including delipidated yolk.

IPC: H01L29/417
Filed: 1984-09-25
Abstract: PURPOSE:To obtain a junction gate type field-effect transistor having self- alignment type gate structure, which has small parasitic resistance and noises therefrom are low, by forming a semiconductor buffer layer having a mixed- crystal composition different from a semiconductor gate layer between the semiconductor gate layer and a gate electrode metallic layer and shaping the gate electrode metallic layer to an eave form to the semiconductor buffer layer. CONSTITUTION:A first metal 5 and a second metal 6 for a gate electrode are patterned to a striped shape in the inverted mesa direction, and only a p type In0.74Ga0.26As0.56P0.44 layer 4 is etched selectively by an etching liquid consisting of sulfuric acid, hydrogen peroxide and water while using the metals 5 and 6 as masks. Only a p type InP layer 3 is etched selectively by an etching liquid composed of phosphoric acid and hydrochloric acid while employing the p type In0.74Ga0.26As0.56P0.44 layer 4 as a mask. The p type InP layer 3 is etched selectively without side etching and takes a form close to approximately verticality at that time. When a third metal 7 is evaporated onto the whole surface, the eave of the gate electrode shaped by selectively etching the p type In0.74Ga0.26 As0.56P0.44 layer 4 forms a shadow, thus isolating both a gate and a source and both the gate and a drain in a self-alignment manner.

Title: Granulation method using nonaqueous medium
Inventor: MORITA KEISUKE
IPC: B01J2/04
Filed: 1987-08-11
Abstract: PURPOSE:To eliminate the necessity of explosion-proof facilities and to ensure safety with an improved working atmosphere, by spray-drying raw powders by the use of tetrachlorodifluoroethane or a tetrachlorodifluoroethane-containing medium. CONSTITUTION:Raw powders of calcia, magnesia, SiC, Si3N4, AlN, etc. are dispersed in tetrachlorodifluoroethane or a medium containing tetrachlorodi fluoroethane to give a slurry. This slurry is spray-dried to obtain granules. Since tetrachlorodifluoroethane has a structure of a substituted ethane in which the hydrogen atoms have been completely substituted with chlorine atoms and fluorine atoms, it is completely non-flammable and, hence, free from the danger of ignition and explosion. Further, when mixed with a flammable solvent such as acetone, ethanol, etc., tetrachlorodifluoroethane shows the property of raising the flashpoint of the flammable solvent or even eliminating the ignitability thereof.

Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a primary locking function due to an elastic locking piece, without losing a secondary locking function and a half-insertion detection function of a retainer. SOLUTION: When a terminal 20 is normally inserted, an elastic locking piece 14 is retracted from a slackness space 15, therefore, a retainer 30 can be pushed into a permanently locking position, and when the incomplete insertion terminal 20 exist, the retainer 30 abuts with the elastic locking piece 14 slackened in the slackness space 15 and cannot be pushed the permanently locking position. Since the locking protrusion 23 and the elastic locking piece 14 are locked outside of the terminal 20, protrusion dimensions of a locking protrusion 23 is free of a restriction caused by the internal structure of the terminal 20, and large locking margin between the locking protrusion 23 and the elastic locking piece 14 can be ensured.
