Title: Air-fuel ratio control device for carburetor
Inventor: TANAKA HIROFUMI
IPC: F02D41/14
Filed: 1989-01-18
Abstract: PURPOSE:To effectively suppress catalytic converter rhodium from overheating by releasing a control by a feedback control means, fixedly holding a flow control valve and changing its position by stages to a low opening side till output voltage is changed to the air-fuel ratio rich voltage, when an engine speed exceeds a predetermined value. CONSTITUTION:When an engine speed exceeds a predetermined value, a control by a feedback control means 20 is once stopped, while a valve holding means 21 fixedly holds to a low opening side a flow control valve 8 throttling an amount of air supplied through an air bleed passage 7. Despite operation thus performed, when output voltage of an oxygen sensor 15 shows a lean condition of air-fuel ratio, the flow control valve 8 is changed in its fixedly holding position further to the low opening side. The above operation is repeatedly performed before the output voltage of the oxygen sensor 15 is changed to air-fuel ratio rich voltage, when the air-fuel ratio obtains a rich condition, the flow control valve 8 is fixedly held in that position.

Title: Pipe cutting method
Inventor: KUNITAKE KENJI
IPC: B23D21/00
Filed: 1984-01-23
Abstract: PURPOSE:To cut a pipe in a highly effecient manner without entailing any material loss as well as to aim at the prolongation of service life in a chaser, by installing a cutting edge circumferentially in an axial central part of a roller, while making up a roller outer diameter smaller in proportion as it comes nearer to axial both ends from the axial central part. CONSTITUTION:Tapers 12 and 12 which make a roller diameter smaller inproportion as it comes nearer to axial both ends from an axial central part where a cutting edge 11 exists are symmetrically attached to the outer circumferential surface of a roller 1 fitted with a cutter. A pipe 3 is rotated as being supported by support rollers 2a and 2b, and the cutting edge 11 of the roller 1 is bitten in the pipe 3 and cuts it, while the roller's outer circumferential surface with these tapers 12 and 12 is forcibly pressed to both sides of a cutting part of the pipe 3, forming it into a taper form. Since this cutting and taper formation are thus performed, chips and protuberances are all in no case produced there, so that both ends are made up into a taper form owing to their diametral contraction and deformation, thus thread cutting is performed so easily with a chaser.

Abstract: PURPOSE:To have favorable storage stability' of a molding material and shorten a curing time of the same in a thermal caompression molding material of an unsaturated polyester resin molding material. CONSTITUTION:An unsaturated polyester molding material containing methyl ethyle ketone peroxide, t-butyl peroxy isopropyl carbonate and t-butyl peroxy-2- ethylhexanoate as a curing catalyst is put into a bathtub mold having a temperature of 145 deg.C and mold-calmped. A cobalt naphthenate solution having a temperature of 120 deg.C is cast to a rear part (a rear side boss part of the bottom of a bath tub) of the molding material within a mold as a curing accelerator through ten casting ports provided within the mold directly after clamping of the mold. Eighty seconds are sufficient for a mold clamping time necessary for molding. Even after storage of the modling material at 20 deg.C, the molding can be performed favorably. In the case where a curing accelerator is not cast, 140 seconds are necessary for the mold clamping time. When the curing accelerator is mixed into the molding material from the beginning, curing is advanced during preparation of the modling material and the molding can not be performed.

Title: Detecting method of leaking place in adiabatic pipeline

IPC: G01M3/18
Filed: 1982-01-26
Abstract: PURPOSE:To detect easily an outbreak place of a leakage, by applying pulse voltage to the one end of an embedded conductive body and measuring the time required for returning the pulse voltage to the other end. CONSTITUTION:At first, a detection apparatus 9 is made ot operate and pulse voltage is outputted from a pulse transmission part 10 at a prescribed time interval. On occasion of not taking place a leakage, the pulse voltage is not received by a pulse reception part 11 because heat insulating materials 4, 6 are electrically nonconductive bodies. On occasion of the leakage taking place, the first and second conductive bodies 7, 8 are short-circuited by a leaking liquid at an outbreak place of the leakage. Accordingly, the part 11 receives the pulse voltage. The value divided the product of propagating velocity of the bodies 7, 8 and time from the transmission to the reception of the pulse voltage into two, is nearly equal to the distance between the leaking place and one end of the bodies 7, 8 because the pulse voltage outputted from the part 10 is transmitted to the part 11 propagating the second conductive body 8, a short-circuit place by the leakage and the first conductive body 7.
