Abstract: In a fastening structure that fastens an exhaust manifold to a cylinder head of an engine, a bolt that extends through a flange is inserted into and fixed to a bolt hole of the cylinder head. The flange includes a contact surface that contacts a coupling surface of the cylinder head, and an inclined surface that is inclined with respect to the contact surface. A clearance is provided between the bolt and the cylinder head inside the bolt hole in a range extending from the coupling surface of the cylinder head to a specified length.

Abstract: A circuit is protected from sudden potential fluctuations that occur in a power ground. An in-vehicle protection apparatus includes a first Zener diode portion, a second Zener diode portion, a diode portion, and an intermediate conductive path. A voltage based on a power source is applied to the anode side of the diode portion. The intermediate conductive path is provided with a branch portion at one end, and forms a path between the cathode of the diode portion and the branch portion. The cathode of the first Zener diode portion is electrically connected to the branch portion and the anode of the first Zener diode portion is electrically connected to a power ground line. The cathode of the second Zener diode portion is electrically connected to the branch portion and the anode of the second Zener diode portion is electrically connected to a signal ground line.

Abstract: A vehicle air bag apparatus includes an air bag disposed anterior to an occupant seat, a peripheral wall portion that surrounds the air bag from outside, and a lid upper wall portion that closes an upper surface opening in the peripheral wall portion, the air bag being inflated and deployed outward through the upper surface opening. The vehicle air bag apparatus includes a rib, disposed in a rear-side corner portion that assumes a portion at which an upper end portion of the peripheral wall portion is connected with the lid upper wall portion. The rib connects the upper end portion of the peripheral wall portion with the lid upper wall portion.

Abstract: Gas is properly fed into a head facing portion while upsizing of an inflator is prevented. Throttle portions are provided for coupling between a frontal side and a backside of an airbag between a neck portion and a head facing portion. Seams are formed as contours of the throttle portions positioned outermost the airbag in a width direction. The seams are parallel to side edge portions, of the airbag positioned outside the seams in the width direction. Seams are formed as contours opposed to the throttle portions arranged adjacent to each other. The seams are approximately parallel to each other.

Abstract: Control for airbag deployment and/or the like is facilitated in a simple configuration. An airbag includes upper vent holes and lower vent holes. The upper vent holes are placed upward of the head facing portion and are open to an occupant side. The lower vent holes are placed downward of the upper vent holes and are open to the opposite side from an occupant.

Abstract: The present invention relates to novel cyclic phosphoric acid amide esters, a process for producing the same and an insecticide containing the same as active ingredient. The present invention provides novel 4-substituted-1,3,2-oxazaphospholidine derivatives of the general formula: ##STR1## wherein R.sub.1 represents an alkyl, alkenyl, alkynyl, aralkyl, aralkenyl or aralkynyl group and R.sub.2 represents an alkyl group. The compounds of the formula I may be produced by the reaction of a compound of the formula: ##STR2## wherein R.sub.1 is as hereinbefore defined or an alcoholate thereof with a compound of the formula: ##STR3## wherein R.sub.2 is as hereinbefore defined and X.sub.1 and X.sub.2, which may be same or different, each represents an atom or group removable as an anion. The compounds of the formula I have interesting insecticidal activity particularly against houseflies, adzuki-been weevil, mulberry mealy bug etc.

Abstract: Novel .beta.-phenoxy- or substituted phenoxy-ethanol compounds or esters thereof expressed by the formula ##STR1## wherein R.sup.1 is a hydrogen atom or an alkyl group, R.sup.2 is a hydrogen atom or a substituent, Y is --OH group or group ##STR2## R.sup.3 is an alkyl group, and n is an integer of 1 to 3. These compounds have juvenile hormone activities, and are useful for hormonal pest control and increased production of silkworm cocoons.
