Abstract: A fire extinguisher including a gas cylinder filled with an extinguishing gas and installed in a cylindrical main casing that has a nozzle head at one end and a spring-loaded bottom cover at another end. The gas cylinder is retained in the main casing by way of a locking pin that extends radially and engages an actuation hole of the main casing; and when the locking pin is manually disengaged from the actuation hole, the gas cylinder is rapidly moved by an expanding spring of the bottom cover in the direction of the axis of the main casing, so that the sealing plate of the gas cylinder is ruptured by a firing pin of the nozzle head, allowing the gas to jet out of the gas cylinder so as to put out a fire. The locking pin can be automatically disengaged from the actuation hole by the use of a temperature sensor.

Abstract: A hair care product contains a yolk antibody (a yolk-derived, anti-hair antibody) which has been obtained from an egg of a domestic fowl immunized using, as an antigen, whole human hair, e.g., normal human hair or human hair damaged by permanent waving, dyeing or bleaching, hair particles obtained by grinding constituent tissues of human hair, the keratin protein extracted from the human hair, or a hydrolysate of the keratin protein.

Abstract: A hand injector for extinguishing fires through a two-stage fire extinguishing operation consisting of a cooling fire extinguishing step and an oxygen deficiency fire extinguishing step uses a fire extinguishing gas, such as a liquified gas including carbon dioxide contained in a cylinder. The hand injector has a firing pin unit for breaking a seal member of the cylinder, a retainer for maintaining the firing pin unit in an inoperative state, and a retainer operating device for operating the retainer by a manual operation. The retainer is fixed at its head portion by a bolt screwed to an upper surface portion of a cylinder receiver. Leg portions of the retainer are fitted in a recess formed in an upper portion of a shaft. A firing pin is fixed to a lower end of the shaft. The retainer operating device consists of a cam, which is adapted to be turned manually, whereby the leg portions of the retainer are opened to operate the fire pin.

Abstract: In order to carry out a two-stage fire extinguishing operation consisting of a cooling fire extinguishing step and an oxygen deficiency fire extinguishing step using a fire extinguishing gas in a closed space, a plurality of fire extinguishers are each provided with a firing pin unit for breaking a seal member of a cylinder, a retainer for maintaining the firing pin unit in a non-operative state, and a retainer operating device for operating the retainer by an automatic operation. The retainer is fixed at its head portion by a bolt screwed to an upper surface portion of a fixing member, and the leg portions of the retainer are fitted in a recess formed in an upper portion of a shaft to a lower end portion of which the firing pin is fixed. The retainer operating unit consists of a tapering shaft member, which is adapted to be pressed by a spring of a shape memory metal expandable at a predetermined temperature, whereby the leg portions of the retainer are opened to operate the firing pin.

Abstract: In order to carry out a fire extinguishing operation by ejecting a fire extinguishing gas having cooling and oxygen deficiency functions and a high fire extinguishing capacity from a plurality of cylinders in succession, a repeating injector is provided with an ejection mechanism which has a magazine containing a plurality of cylinders filled with such a fire extinguishing gas and detachably fixed to a receiver barrel constituting an injector body, and which is adapted to break a seal member on a head portion of each of the cylinders by a triggering operation and eject the fire extinguishing gas, and a cylinder renewing mechanism for discharging a cylinder, which has been subjected to the ejection of the fire extinguishing gas and become empty, by knob-pulling operation, and renewing the cylinder successively.

Abstract: In order to carry out a two-stage fire extinguishing operation including a cooling fire extinguishing operation and an oxygen deficiency fire extinguishing operation using a fire extinguishing gas, a cylinder filled with a liquefied gas of carbon dioxide is used, and a firing pin unit for breaking a seal member of the cylinder, a retainer for maintaining the firing pin unit in a non-opereted state and a retainer operating device for automatically operating the retainer on the basis of stored temperature data are provided. The retainer is fixed at a head portion thereof by a bolt screwed to the upper surface region of a fixing member, and leg portions of the retainer are fitted in an upper recess in a shaft to a lower end portion of which a pin is fixed. The retainer operating device consists of a retainer turning member provided with projections on one end portion thereof.

Abstract: The present invention is directed to a method for producing crude sialic acid, comprising hydrolysis of a delipidated egg yolk and a method for producing high purity sialic acid, which comprises desalting a solution containing sialic acid obtainable by hydrolyzing a delipidated egg yolk, adsorbing sialic acid to an anion exchange resin and then eluting said sialic acid.The present invention makes it possible to produce and purify sialic acid from delipidated egg yolk on an industrial scale.

Abstract: A lighting apparatus is provided which comprises a color disc capable of transmitting light therethrough and arranged within a housing having an opening. The color disc has a planar surface parallel to the opening, and a large number of subdivided sections defined on the planar surface. The subdivided sections are individually colored in one of a plurality of colors such that, when viewed as a whole, the planar surface has a plurality of identical coloration patterns each consisting of the subdivided sections of the same color and that any adjacent ones of the coloration patterns are different in color from each other. A shutter disc is arranged between the color disc and the opening and has a large number of windows for permitting only those subdivided sections forming one of the coloration patterns to be exposed to the outside of the housing when the shutter disc is at a predetermined rotational angle position.

Abstract: The extinguishing apparatus of this invention comprises a cartridge casing provided with a jet nozzle device, a flexible extinguishing liquid cartridge which is coupled in plug-in manner to the jet nozzle device by inserting from the open end of the cartridge casing into the interior of the casing, a cap for closing the open end of the casing, a joint for coupling the interior and exterior of the cartridge casing, and a discharge unit for coupling by plug-in manner to the joint. The cartridge is made possigle to discharge the extinguishing material, when it is compressed by a force from the outside, and the discharge unit feeds incombustible high pressure gas into the cartridge casing either automatically when the temperature of environment is reached over a predetermined temperature, or by handling manually. Aaccording to this, the cartridge is compressed, the extinguishing material discharged from the cartridge is jetted from the jet nozzle device.
