Title: Total organic carbon analyzer
Inventor: MATSUI MASAMI
IPC: G01N25/22
Filed: 1988-12-29
Abstract: PURPOSE:To make the amount of specimen injection constant regardless of the concentration of carbon and to make it possible to perform highly reliable measurement by connecting a flow-path switching mechanism between a carbon dioxide transformer and non-dispersion type infrared-ray gas detector, and selecting a flow path. CONSTITUTION:When a specified amount of sample solution is injected into a combustion furnace, organic and inorganic carbons in the solution are transformed into carbon dioxide gas. The carbon dioxide gas intactly passes through an inorganic carbon reaction furnace 12 and flows into a non-dispersion type infrared-ray gas detector 31 through a path which is selected with a range switching mechanism 20. After the concentration of the gas is measured, the same sample is injected into the reaction furnace 12 by the same amount. Only the inorganic carbon in the sample is transformed into carbon dioxide gas. The carbon dioxide gas flows into the detector 31 through the mechanism 20. The mechanism 20 can select a path through which the sample can directly flows in and a path wherein the sample is divided at a constant ratio so that one is made to flow directly and the other is made to flow through a carbon- dioxide-gas absorbing pipe 27. When the sample has the high concentration, the sample is diluted so as to prevent the decrease in accuracy of the detector 31. Thus the accurate measurement can be performed.

IPC: H05K7/10
Filed: 1990-11-30
Abstract: PURPOSE: To eliminate the need of soldering by an arrangement wherein the end part making a downward angle with respect to the lead of an integrated circuit is applied with a lateral force by tightening a holding means thereby applied with a downward force for holding the lead on a contact. CONSTITUTION: When a device fixed with a package 20 is fixed to a PC board 21, a holding means, e.g. a shoulder screw, inserted into a fixing hole 29 is tightened to push a device 10 pushed down toward the PC board 21. Since the center of rotation of a beam 14 is located at a top point 31, the beam 14 generates an upward force 33 which is reverse to a downward fixing force 30. When the end part 16 of the beam 14 pushes the foot 24 of a lead, the beam 14 turns about the top point 31 to apply an upward force to the end part 16 and an inward force 34 directing toward the vertical part 25 of the lead. Consequently, a good electrical contact can be made between a solder pad 22 and the foot 24 of a lead.

Title: Method and device for clipping segment
Inventor: KITAHARA JUNJI
IPC: G09G5/36
Filed: 1990-11-30
Abstract: PURPOSE:To shorten a time required for plotting the whole graphic and to make it unnecessary to execute division and multiplication by repeating processing for obtaining the 2nd shift down value and processing for correcting the 1st shift-down value until a smaller interval becomes equal to the 1st shift- down value. CONSTITUTION:After waiting the input of an end point coordinate value (Xe, Ye), a direction to be clipped and the coordinate value of a boundary for clipping a segment,  Xs,  Xe,  X are calculated and which is larger,  Xs or  Xe, is decided. When  Xs> Xe, the end point is determined as a reference point, and when  Xs<= Xe, the start point is determined as the reference point. Then a relative distance is corrected based upon the 2nd shift-down value shifted down so that a difference of an interval between the end point and the boundary from the relative distance is equal to a bit length and the correction of the relative distance is repeated until the interval becomes equal to the relative distance. Consequently the time required for obtaining the intersecting point can be sharply shortened and the use of a multiplier and a divider can be made unnecessary.
