  • Patent number: 10662822
    Abstract: A heat cycle system includes a cooling circuit and a Rankine cycle circuit in which an organic medium circulates. The Rankine cycle circuit includes an evaporator, an expander, and a condenser. Before warm-up of an engine, a control device executes a warm-up mode in which the organic medium is circulated through the condenser, the expander and the evaporator in sequence; after the warm-up of the engine, the control device executes a waste heat recovery mode in which the organic medium is circulated through the evaporator, the expander and the condenser in sequence. In the warm-up mode, by supplying energy to the expander, the control device compresses the organic medium passing through the condenser and supplies the compressed organic medium to the evaporator; in the waste heat recovery mode, by depressurizing the organic medium passing through the evaporator by the expander, the control device recovers the energy generated by the expander.

  • Patent number: 5592758
    Abstract: A ski boot which can improve the insertion and removal of a skier's foot, provide an excellent fastening feeling by fastening members, enhance the durability of a connecting portion between a cover member and a shell main body, and eliminate the possibility of water leakage. A slit is formed in the upper portion of separated & overlapping portions of a shell main body separated right and left and extending from an upper opening to an instep area of the shell main body. The slit and separated & overlapping portions are covered with a cover member from the toe portion of the shell main body to the upper opening thereof. A plurality of fastening members are used to fasten a trunk portion to be inclinably mounted to the shell main body as well as fasten the separated & overlapping portions.

  • Patent number: 5379531
    Abstract: A fastening device 7 for fastening a skier's foot inserted in an outer shell 1 of a ski boot. A lock member 17 having an operation portion 16 and an engagement portion 15 is disposed in one of a clamping-lever 11 or the outer shell 1, and an engagement portion 20 is provided in the other. The engagement portion 15 of the lock member 17 can be resiliently moved by a biasing spring 18 into engagement with the engagement portion 20 to thereby secure and hold the clamping lever 11 at the clamping position thereof. This makes it sure to prevent the clamping lever from releasing its clamping force due to shocks given when the skier skis in a heavily bumpy slope.

  • Patent number: 4991320
    Abstract: The present invention relates to ski boots which can keep appropriate forward tilt pressure, wherein when the boots are tilted forwardly an alastic section is pressed toward the toe side by a mating part which is formed in a front cuff, therefore this elastic restoring force of the elastic section can generate an appropriate elastic force.

  • Patent number: 4881330
    Abstract: A ski boot consisting of an outer shell and an innerboot installed inside the outer shell. The outer shell is formed out of thermoplastic synthetic resin material mixed with a desired weight ratio of whisker. Mixing of whisker not only increases the flexural elasticity of thermoplastic synthetic resin material but also reduces the elastic distortion of the outer shell. Further, the abrasion-resistance of the outer shell is improved.

  • Patent number: 4391419
    Abstract: A drag adjusting device of spinning reel for fishing. The device has a cylinder projecting rearwardly from a reel housing and provided with an axial groove and stopper projection formed on its inner and outer peripheral surfaces, respectively. A spool slide shaft having the spool fixed to one end thereof projects into the cylinder from the bottom of the latter. The device further has a braking member consisting of two washers fitted to the spool slide shaft. One of the washers is adapted to rotate as a unit with the spool slide shaft, while the other fits the axial groove of the cylinder and, hence, is not rotatable. An adjusting cylinder is screwed to the outer end opening of the cylinder so as to be able to move back and forth with respect to the latter as it is rotated. The braking member is pressed by a spring acting between the inner bottom surface of the adjusting sleeve and the rear end surface of the braking member.
