Title: Production of cyclopentadienes
Inventor: MATSUMURA YASUO
IPC: B01J21/06
Filed: 1994-09-29
Abstract: PURPOSE: To provide a method for producing cyclopentadienes useful as an intermediate for organic synthesis in high yield by a simple reaction process from an inexpensive raw material. CONSTITUTION: An unsaturated carbonyl compound of formula I (R1 to R3 and R5 are each H or a 1-4C alkyl; R4 is H or a 2-4C alkyl) is subjected to cyclodehydration in vapor phase at 120-600 deg.C, preferably 250-500 deg.C and under <=10kg/cm<2> , preferably normal pressure or 5kg/cm<2> to produce cyclopentanednenes of formula II (dotted line of 5 membered ring exhibits that the 5-membered ring contains two double bonds). Silica, alumina, zinc oxide, titania, zirconia or mixture thereof can be exemplified as the solid acid catalyst and further, attached carbon can be reduced by supporting an alkali metal on these catalysts. The catalyst lowered in activity by long term use can reproduce initial activity by decoking the catalyst by air, etc., at high temperature of about 500 deg.C.

Title: Ventilation fan
Inventor: ONCHI TOSHIHIKO
IPC: F24F7/10
Filed: 1985-11-21
Abstract: PURPOSE:To prevent outdoor air from being sucked up through an opening thereby to efficiently discharge indoor air by forming a blower at one side of a natural ventilation opening to smoothly carry out ventilation due to natural wind, and carrying out ventilation while closing the opening by a laminar flow formed at the blow-off port of the blower in a forced ventilation. CONSTITUTION:A blow-off port 6 is formed along the entire width of the upper part of a ventilation grill 5, and is also formed toward the lower inner surface of a frame part 4. A blower 8 is formed at a part upper than the blow-off port 6, and does not project into the rear pace of the ventilation grill 5. Air sucked up through under the floor A flows as shown by arrows. Air blown off through the blow-off port 6 blocks the outdoor side of the ventilation grill 5 in the form of a laminar flow. and prevents natural wind from flowing into through the ventilation grill 5, and is discharged to the outdoor. Therefore, air under the floor A is efficiently discharged, and further the laminar flow due to the blow-off port 6 entangles indoor air of the ventilation grill 5 whereby an exhaust air flow shown by a dotted arrow is formed and the discharge of air under floor is promoted.

Filed: 1990-09-28
Abstract: PURPOSE:To improve durability by stopping a rotary contact disc and contact shoes in a given position so as to prevent breakage thereof at a wiper arm stop position part even when a wiper arm is pushed back by means of snow during snow fall. CONSTITUTION:When a motor run in a forward direction and a wiper arm is causes to effect wiping movement, an engaging member 9 on the drive side is rotated forward together with a disc member 3 formed integrally with an engaging member 7 on the gear side.

Filed: 1984-12-12
Abstract: PURPOSE:To prevent stopping of a controlling system without completing control of equalizing regularly by resetting a gain controlling circuit and a convergence deciding circuit and restarting when the convergence deciding circuit does not output a signal that indicates completion of compensation of line loss after lapse of specified period. CONSTITUTION:A frequency divider 6 counts clock B applied to a clock terminal, and when the counted value becomes (n), outputs a signal C of '1'.

Even when the signal C becomes from '0' to '1', if signal F becomes '0' to '1', that is, equalizing is not completed, a signal D becomes from '1' to '0'. Thereby, resetting is made to a gain controlling circuit 2, a convergence deciding circuit 3 and the frequency divider 6, and equalizing control becomes initial state, and equalizing control is executed again from the beginning. At the same time, the frequency divider also becomes initial state, and frequency dividing is started again.

IPC: G08B17/00
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To select a discharge nozzle most suitable for a fire extinguishment and efficiently perform the fire extinguishment by determining the bias angle of a fire detector from a reference line on the basis of the turning angle of each fire, detector, and comparing the bias angle of each fire detector. SOLUTION: When two fire detectors 3, 4 detect a fire sources FP or heat source, the turning angles θ1, θ2 of discharge nozzles 5, 6 are transmitted to a central control board. The XY coordinates of the fire detectors 3, 4 and the crossing angles ψ1, ψ2 of a reference line 11 with the base lines 3S, 4S of each fire detector 3, 4 are preliminarily inputted to the central control board, and the bias angles, or the angles α, β formed by straight lines 3A, 4A with the reference line 11 are calculated from the crossing angles ψ1, ψ2 and the turning angles θ1, θ2. The bias angles have the relation of α>β, 0<α<π/2, 0<β<π/2.  The bias angles α, βare compared to select the larger bias angle α, and the discharge nozzle 5 corresponding to the fire detector 3 having this bias angle α is selected. The reason is that the detector having the larger bias angle is closer to the fire source FP.
