Title: Air pressure controlled infusion apparatus
Inventor: CHIN CHUZAN
IPC: A61M5/142
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To enable the captioned apparatus to be carried handily with a smaller size by introducing pressurized air into a space between inner and outer bags being controlled by a pressure control section so that a liquid medicine flows out by a specified value from the inner bag to achieve infusion accurately regardless of the position of an infusion bad. SOLUTION: When a pneumatic supply source 20 is mounted at an inlet part 32 of a pressure control part 30, the closure of a closed container 21 is released and high pressure air inside flows out of an outlet. The high pressure air alone subjected to the first stage control limited to a specified pressure is supplied to a first chamber and further, enters a second chamber so that the air alone subjected to the second stage control limited to a specified pressure flows out. The air flows into a pace 12 between an inner bag 11 and an outer bag 13 through a hose 17 from an outlet part 37 to pressurize the inner bag 11. Thus, a liquid medicine M inside flows out to a liquid medicine supply hose 3 by a specified amount per unit time from a cannula needle 4a by a pressure suitable for the pressure of a vein to be sent into a blood vessel.

Title: Limit position detector and control method thereof
Inventor: IWATA YOSHIHIRO
IPC: A61H15/00
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To prolong a life of a limit position detecting switch and to lower current consumption by performing control so that a moving object is returnes to the position, in which a movable part is not pressed, when the movable part of the limit position detecting switch is pressed by the moving object. SOLUTION: A movement control means 4 gives a moving means 2 an instruction for moving a moved object 3 in the movement direction A until it reaches a movement limit position X1. The movement control means 4 gives the moving means 2 an instruction for moving the moved object 3 in the movement direction B when the moved object 3 pressed a movable part 1a so as to reach the movement limit position X1 and a limit position detecting switch 1 is turned on. The movement control means 4 gives a movement stopping instruction when the moved object 3 is returned to a position X2, in which it does not press the movable part 2a, and the limit position detecting switch 1 is turned off. The limit position switch 1 is turned on for only a few time when the moved object 3 reaches the movement limit position X1 and does not continue acting for a long term, so that applied stress can be lowered.  This mechanism is used for a moving mechanism unit returning a massaging arm to a reference position in an electric massage chair.

Title: Horizontal deflecting circuit
Inventor: YAMANOI TAKAHIRO
IPC: H04N3/23
Filed: 1987-05-14
Abstract: PURPOSE:To obtain a circuit to maintain the horizontal deflection width constant even when a high-voltage part varies by taking out the high-voltage variable from the secondary-side high voltage windings of a flyback transformer, and superposing the result on a side pin correction signal to control the horizontal deflection width. CONSTITUTION:When a high voltage tends to drop, a transistor TR 23 shifts in the cut-off direction corresponding to a high-voltage variation signal HV, TR 16 also shifts in the cut-off direction, so that such a control voltage signal CON as making the horizontal deflection width smaller is impressed to a connection middle point A. When the high voltage tends to rise, a signal HV is supplied to the TR 23 via a resistor 21 and a capacitor 22 to shift the TR 15, 16 to the conducting direction, so that such a signal as making the horizontal deflection signal larger is impressed to the point A. When the content of a picture rapidly changes to make a high voltage considerably variable, the variation is suppressed to a prescribed voltage by means of diodes 26, 27, and the titled circuit so as not to vary high voltage drastically.
