Title: Communication quality setting method
Inventor: MORITA HIROSHI
IPC: H04L12/70
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To efficiently set communication quality from a data packet transmission terminal to data packet reception terminals by generating a table for associating communication quality which is set on a communication line with a traffic characteristic to be transmitted for a data packet transmission terminal and deciding communication quality by referring to the table prior to the transmission of data. SOLUTION: When the data transmission terminal 201 knows communication quality corresponding to the traffic characteristic of the data packet to be transmitted, it transmits a quality setting packet to data reception terminals 202 and 203 prior to the transmission of the data packet. Routers 208-213 through which the quality setting packets pass set communication quality for a line interface and the data reception terminals 202 and 203 receiving the quality setting packet set communication quality for the received interface. Thus, the transfer of the data transmission terminal 201 and the data reception terminals 202 and 203 can be reduced prior to the transmission of the data packet.

Abstract: PURPOSE:To simplify the constitution of a high voltage generating circuit, and reduce the power consumption of a device, by constituting the high voltage generating circuit in the device by a pulse voltage generating circuit applying timing pulses obtained from a synchronizing circuit and a circuit to operate amplitude summing of the pulse voltage. CONSTITUTION:A high voltage generating circuit 4 in a device is constituted by a pulse voltage generating circuit 6 and an adder 7.

Abstract: PURPOSE:To improve the civil engineering work capacity at a low manufacturing cost by forming a block anchor in combination of a U-shaped metal fitting and a chain, and setting the block anchor on a catch portion of a building block from above to be caught by the central chain. CONSTITUTION:A block anchor is formed by combination of a U-shaped metal fitting and a chain for a motorcycle or the like. When a block catching recess portion is positioned in front, the inside of the chain is joined and the inside of the metal fitting is joined to the block back recess portion to pull up an ordinary chain connected to the chain for the motorcycle or the like, a block is pushed down in a 90-degree arc while being caught. Whereupon, the weight put on the metal fitting strengthens fastening of the chain. If an ordinary chain is used in a fastened place, however, the chain is twisted to be temporarily made shorter and suddenly loosened at the time of moving the block, or if the block is placed temporarily on the ground, sometimes it can not pull up the block again thus a good effect can be obtained by using a chain for a motorcycle or the like for limiting a fixed motion.
