Abstract: PURPOSE: A novel substituted furan derivative is used as a starting material and the reaction is effected under an acidic condition to produce cyclopentenolone used as an intermediate of agricultural chemical and medicine with simple operations in high yield without environmental troubles.  
     CONSTITUTION: A furan compound of formula I (R 1  is methyl) is reduced to an alcohol, which is made to react with a halide to give a compound of formula II (R 2  is alkyl, alkenyl, alkynyl). Further, the compound of formula II is made to react with chlorine or bromine to form a novel substituted furan derivative of formula III(n is 5 or less; R 3  is alkyl; A is O or S). The furan derivative is used as a starting material and the reaction is effected in a solvent such as water or methanol in the presence of an acid such as sulfuric, acetic or phthalic acid at 0°C to the boiling point to give cyclopentenolone of formula IV.

IPC: F15B11/08
Filed: 1979-07-17
Abstract: PURPOSE: To freely and easily carry out a control of an actuator, by communicating a back pressure chamber of each check valve constituting a control valve with an auxiliary valve through a reducing valve whose pressure setting can be varied by an operation lever.  
     CONSTITUTION: A control valve 2 is constituted with a combination of the first, second, third and fourth check valves 41, 42, 43, 44. The back pressure chamber of each of the check valves 41, 42, 43, 44, is communicated with an auxiliary pump 5 via reducing valves 7, 8 whose pressure settings can be varied by an operation lever. By such an arrangement, the pressures of the back pressure chambers of the check valves 41, 42, 43, 44 can be selectively raised in response to the tilting direction and angle of the operation lever 9. Consequently, by suitably selecting the manipulation direction and angle of the operation lever 9, it is possible to control the actuation direction and speed of an actuator 3, resulting in a free and easy control of the actuator.

Title: Method and device for protecting patient from blood vessel burst by catheter balloon
Inventor: FUIDERU ETSUCHI SHIRUBA
IPC: A61M25/00
Filed: 1991-03-29
Abstract: PURPOSE:To prevent a blood vessel from bursting by inflating a catheter balloon by injecting gas into the balloon till an internal pressure in the catheter balloon reaches the first preset level, and relieving the gas to a closed space positioned outside a body of a patient. CONSTITUTION:When a syringe plunger 44 is pressed into an outer cylinder 42 of a syringe 40, a gas pressure is transmitted to a balloon charmel through a relief flow pipe 56 and to a catheter balloon 26 through an insertion pipe 20. The balloon 26 is brought into contact with an internal wall of a blood vessel in cooperation with the gas pressure, tightened and not further inflated. When the plunger 44 is further pressed in, gas is further fed into a closed catheter system. However, when a pressure in a system is increased, a safety member 66 of a gas reservoir is started to inflate to release the gas from a relief hole 68. An internal pressure of the system is prevented from exceeding a maximum pressure 600mmHg at which the safety member 66 of the gas reservoir is burst. Surplus gas, not cleared fed into the catheter balloon 26, is safely released into the gas reservoir safety member.
