Title: Curve interpolation forming system
Inventor: MASAKI SHIGEKI
IPC: G06T11/20
Filed: 1987-10-26
Abstract: PURPOSE:To easily form a curve and to correct a form by calculating the form only of a curved segment by the use of the tangential vector of both the end points of the form corrected curved segment. CONSTITUTION:After the position coordinate of a control point considered to be improper included in the blocks P3-P5 for correcting the form of the curve is corrected, the corrected block is defined to be a new curve forming block to apply the position coordinate of a control point 4' included in the curve forming segment and the tangential vector value stored in the control points P3-P5 in both the end points of the curve forming block and calculate the curve form of the corrected block by an interpolating function again under a fixed termination condition. Thereby, even when the position coordinate of the control point of the corrected block is changed, the curve form except the corrected block can not be changed but the curve can be smoothly connected at both end points of the corrected block.

Filed: 1988-10-26
Abstract: PURPOSE:To control plural terminal units in a short time by forming a group including plural terminal units and providing a simultaneous control mode signal at a transmitting signal to send from a central processing unit to a terminal unit. CONSTITUTION:A group including plural terminal units is formed and a mode signal to be able to designate a simultaneous control mode to control simultaneously all terminal units in one group to a transmitting signal to send from a central processing unit to a terminal unit is provided. Namely, an address signal AD is expressed by, for example, the binary number of 8 bits, when a mode signal MD designates a simultaneous control mode, the high order 4 bits of the address signal AD become an individual address and the low order 4 bits become a group address. At this time, a terminal unit 2 having the same group address is considered to be one group and simultaneously controlled by a control signal CT included in one transmitting signal TR. Thus, the time necessary to operate plural terminal units can be shortened.

Title: Sealed alkaline secondary battery
Inventor: KONDO MASATSUGU
IPC: H01M4/62
Filed: 1987-10-27
Abstract: PURPOSE:To obtain good charge and discharge cycle characteristics by using Zn including addition of Pb amalgamated by mercury for a negative electrode. CONSTITUTION:A sealed alkaline secondary battery is formed of a positive electrode case 1, a positive electrode 2 mainly consisting of Mn dioxide, a positive electrode ring 3, a separator 4, impregnant 5, a sealing ring 6, a negative electrode 7, and a sealing plate 8 acting also as a negative terminal.

Abstract: PURPOSE:To increase a measurement precision for a fuel leakage amount so as to improve reliability in good/defect determination by detecting a condition change in fuel, which leaks to a leakage fuel sump chamber communicated with an injection part of a fuel injection valve. CONSTITUTION:A fuel injection valve 1 is positioned in a set platform 20, and a pressure in a valve chest 16 is increased when fuel is fed to a fuel supply port, 13 from a fuel supplying unit 19 at a pressure close to an actual using condition. During the increase of the pressure, fuel in the valve chest 16 leaks from between a valve seat 8 and a valve unit 12, and the leakage fuel flows from a sack hole 7 into a leakage fuel sump chamber 22 via an injection hole 6. When a pressure of the sump chamber 22 is increased, a float 23 is shifted, and a detection object unit 23a of the float 23 is brought close to a reference object unit 25a of a displacement sensor 25. Subsequently, the displacement sensor 25 outputs a float displacement distance DELTAX and its displacement time DELTAT to a data processing unit 26, so that a fuel leakage amount Q per unit time is detected. In addition, the data processing unit 26 compares the reference leakage amount and the measured leakage amount with each other so as to determine whether it is a good item or not, and information that it is a good/defective item is indicated in a display unit 27.

Title: Flame-retardant phenolic resin foam
Inventor: KODERA SATORU
IPC: C08J9/04
Filed: 1985-12-02
Abstract: PURPOSE:To provide a phenolic resin foam having high flame retardance, excellent processability, physical properties, etc. and suitable for use as a ceiling material, a heat insulating material, etc., containing a phosphorus compd. and aluminum salt of a strong acid in combination as flame retarders. CONSTITUTION:A phosphorus compd. (e.g., ammonium phosphate or phosphoric acid) and aluminum salt of a strong acid having pKa<=2.5 (e.g., aluminum sulfate or aluminum chloride) are added to a phenolic resin. Further, additives such as a blowing agent, a foam stabilizer, a curing catalyst, etc. are added thereto and the mixture is expanded by heating to obtain the desired flame-retardant phenolic resin foam. Under high-temperature conditions, the phosphorus compd. is self-condensed to form water, whereby heat generation during combustion is inhibited. At the same time, the carbonization of the resin foam proceeds and a high flame retardance imparting effect can be exhibited by the synergism of the carbonization of the foam and the carbonization promoting effect of the aluminum salt of the strong acid.
