  • Publication number: 20160157547
    Abstract: A ventilating device is disclosed. The device includes a bag-shaped body with an upper part open using a first guiding sheet and a second guiding sheet. An attachment device attaches the bag-shaped body to the helmet. An air blower takes in outside air into the bag-shaped body and sends it out to a side of an open portion of the bag-shaped body. The second guiding sheet is located on a side of a human body and the first guiding sheet is located on an outer side, the air taken into the bag-shaped body is led to the open portion of the bag-shaped body along the first guiding sheet and the second guiding sheet and introduced into the helmet through an air inlet formed between an inner edge of the helmet located close to the open portion and a head of a user to ventilate the inside of the helmet.

  • Patent number: 8129013
    Abstract: There is provided a human-body aimed spacer for restricting rugged feeling, which is flexible and light-weighted and requires only a smaller storage space. The spacer comprises a number of convex parts 20, and flexible connecting portions 26. The convex parts 20 each comprises: a frame-like portion 21 formed at a side contacting with a human body; four column portions 22, each having one end continuing to the frame-like portion, and each being formed to rise from the frame-like portion; and a rising-portion integrator 23 for interconnecting the other ends of the column portions 22 with one another. The flexible connecting portions 26 each interconnect adjacent ones of the frame-like portions 21 with each other. The spacer is configured to contact with a human body at the side where the frame-like portions 21 are formed, and to abut on a cushion or the like at the side where the rising-portion integrators are formed.

  • Patent number: 6786273
    Abstract: A seat cushion has cooling flow passages that are provided in a substantially parallel and planar manner. Air at a temperature lower than the body temperature is blown through the cooling flow passages substantially parallelly to the body surface of a person sitting on the cushion. As a result, the temperature gradient near the body surface is increased so as to release heat from the body, resulting in a feeling of coolness.

  • Patent number: 6619382
    Abstract: The present invention provides a cooling device aimed spacer capable of flowing a lot of gas even by a lower pressure. Such a cooling device aimed spacer is used to form a cooling flow passage of a cooling device. The “cooling device” is to cool a user's body by flowing, by blowing means, a gas through a substantially flat flow passage formed at that side of the cooling device which contacts with the user's body. The cooling device aimed spacer comprises: a plurality of column-shaped members 32a each having a length component in the thickness direction of the cooling flow passage, and a plurality of connecting members 33a for connecting the tip ends of the plurality of column-shaped members 32a. The plurality of column-shaped members 32a are integrally formed to become physically continuous via base member 35. Further, the width of each of the column-shaped members 32a along a direction perpendicular to the gas-flowing direction is in a range of 0.

  • Publication number: 20030047301
    Abstract: Each of the cooling bedclothes, cooling seat cushion, cooling mat, cooling chair, cooling clothing and cooling shoes, to which the present invention is applied, has such a commonized structural feature to form the cooling flow passages in a substantially parallel and planar manner in the portion of such an article adjacent to the body, and utilizes such a commonized cooling effect to cause the ambient air at a temperature lower than the body temperature to flow through the cooling flow passages substantially parallelly to the body surface to thereby cool the body. Namely, the present invention forms, at a location extremely adjacent to the body surface of a person, an air layer having a temperature equal to that in the room without lowering the temperature of the whole room, thereby forcibly increasing the temperature gradient near the body surface to thereby increase the extent of heat release from the body, resulting in feeling of coolness.

  • Patent number: 5077600
    Abstract: A convergence measurement apparatus for a color CRT comprising a light sensor which is placed on the face of a CRT to be tested, a CPU, and a pattern generator which causes a plurality of luminescent lines of a primary color to be displayed on one area of the CRT screen and a plane area comprised of a composite of the two other primary colors to be displayed on another area of the screen. The plurality of lines are shifted at a given rate along the designated area of the screen, the color of the displayed lines successively changing to show each primary color. The light sensor receives light intensity information from the generated pattern and the CPU calculates a mis-convergence value based on the light intensity data. The apparatus further includes a self-inspection feature by which the processing is executed for successive measurement of the same primary color.
