摘要:
An apparatus for electrically blasting a number of electric detonators arranged at a plurality of working faces, including a single controller having a power source unit for supplying a D.C. voltage and a plurality of ignition control units for selectively applying the D.C. voltage; a plurality of oscillators each arranged near respective working faces, the number of the oscillators corresponding to that of the ignition control units, each oscillator being energized with the D.C. voltage to generate a high frequency current and being connected to respective ignition control units via an electric wire bundle; and a plurality of lead wires each connected to outputs of respective oscillators. Loop-like leg wires of electric detonators are electro-magnetically coupled with the lead wires with the aid of transformer magnetic cores.

A loop portion of a bus wire connected to an electric blasting device is passed through a first magnetic core together with a first loop-like wire, and the first loop-like wire is further passed through a second magnetic core provided in a detonator. The detonator includes a second loop-like wire which is passed through the second magnetic core, an electric bridge connected to the second loop-like wire and a fuse head provided around the electric bridge. When a pulsatory high frequency current is supplied to the bus wire, high frequency currents are induced in the first and second loop-like wires by electromagnetic induction. Then the current flows through the electric bridge of the detonator to fire the primer explosive.

A safety belt take-up device provided with a double sensing type emergency-lock mechanism comprises webbing draw acceleration sensing means, vehicle acceleration sensing means, first transmission means and lock means. The webbing draw acceleration sensing means may shift from a first position to a second position when a webbing is drawn out at an acceleration greater than a predetermined value. The vehicle acceleration sensing means may shift from a first position to a second position when the vehicle acceleration has exceeded a predetermined value. The first transmission means is connectible to a take-up spindle along with the shift from the first position to the second position of the webbing draw acceleration sensing means and/or the vehicle acceleration sensing means and adapted to shift from a first position to a second position due to the webbing draw-out force. The lock means may prevent the draw-out of the webbing when the first transmission means has shifted to its second position.

In this application, an antiobesity or antihyperlipidemic food, feeding stuff or supplement containing lysine component(s) that is characterized in that said food, feeding stuff or supplement contains lysine component(s) at such rate that 40 to 160 mg in terms of free-form lysine should be taken in per kg of body weight per day, under diet conditions under which the daily protein energy composition is 20% or less, and an antiobesity or antihyperlipidemic food, feeding stuff or supplement containing lysine component(s) that is characterized by containing said lysine component(s) in an amount of 0.8 to 3.0 wt % in terms of free-form lysine on the basis of the dry matter and having a protein energy composition of 20% or less are disclosed. According to the present invention, a method that can realize a reduction in body weight or body fat, suppress weight increases, or improve hyperlipidemia for obese persons or persons concerned about increases in their body weight, safely and to the fullest extent and a method that can eliminate the fat of unnecessarily obese animals, or control obesity, can be provided.

A retractor has a webbing take-up shaft rotatably supported in a base, a biasing member for biasing the take-up shaft in a webbing take-up direction, a connecting member for connecting one portion and another portion of the biasing member, a locking member movably provided in the base and engageable with the connecting member, and a control device for controlling the condition of the locking member. The locking member is capable of assuming a locking position in which it is engaged with the connecting member to prevent the biasing force of the other portion of the biasing member from acting on the take-up shaft and a non-locking position in which it is in non-engagement with the connecting member to permit the biasing force of the one portion and the other portion of the biasing member to act on the take-up shaft, and when the locking member is brought to the locking position by the control device, it is movable away from the connecting member when the connecting member moves with the take-up shaft rotating in a webbing draw-out direction.

In a seat belt device including at least a belt for constraining the upper half of the body of a seat occupant, the shoulder belt, when in occupant constraining position, is guided so as to prevent the end portion of the belt adjacent to the shoulder of the occupant from bearing against the neck or the head of the occupant.
摘要:
A seat belt buckle device having a latch device comprising a base, a latch member pivotally supported on the base and having a latching portion for locking a tongue, the latch member being biased into a tongue locking position, a push button adapted, when operated, to bring the latch member into an unlocking position, and a cover having an inlet port for inserting the tongue therethrough and an opening for operating the push button therethrough. The latch member is pivotally supported on a supporting bed secured to the base. The latch device further comprises means for holding the latch member in its unlocking position when the latch member is brought from its tongue locking position to its unlocking position by the push button, whereby the latch member is held in the unlocking position until the latch member is brought back to its tongue locking position after the tongue is again inserted in the inlet port.
摘要:
An improved automatic locking retractor for use with a seatbelt system designed to operate with improved reliability while having a simplified structure. An improved control mechanism is provided for governing the locking of the seatbelt system when appropriate. The control mechanism is a control plate which cooperates with a latch plate which in turn cooperates with the take-up reel of the seatbelt system. Movement of the control plate controls the movement of a locking lever which selectively locks the latch plate to lock the take-up reel when appropriate.
