CONSTITUTION:The solar heat hot water feeder A is formed of a heat collector 1, a  circulation pump 2 and a solar heat accumulation tank 3 and the course of the hot  water switched to the hot water heater 4 from the hot water feeder A is formed by  the electrically operated three-way valve 7 so that the hot water from the water heater 4 is guided to a hot water feeding port 5 by the valve 7. Further, the operation of  the valve 7 is performed by the control section 8 after the detection of the temperature of the hot water in the solar heat accumulation tank 3 by a thermosensor 6. In  the control section 8, a desired hot water temperature is set in advance by a temperature adjuster 12, the temperature detected by the thermosensor 6 is displayed by a display device 14 and compared to the set temperature by a comparator 13 and two kinds  of voices are anounced through a speaker 16 in proportion to the loudness of the  voices. Consequently, the user may switch properly the three-way valve 7 by a switch  17 in response to the two kinds of voices.

Title: Foaming roller and its production
Inventor: NAGATA YUKINORI
IPC: F16C13/00
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To improve the dimensional precision of a roller and to make its conductivity uniform by making the outer and inner surfaces of a rubber tube or the cross-sectional shapes perpendicular to the axis of the tube of the outer inside surface polygonal. SOLUTION: A core bar holding member 11 is fitted to a mold end part so that a rubber material 13 before foaming/vulcanization, molded in a non- similar shape to a mold inner surface, can be inserted into a mold 10 in the shape of a concentric circle with a core bar 12. The member 11 regulates a flow in the longitudinal direction of a material and has a vent hole. The core bar and the material are charged in the mold and heated to to be vulcanized and foamed simultaneously. In the initial stage of foaming, the entire rubber tube is expanded nearly keeping its form. In an advanced stage, since the shapes of the mold and a charging shape are non-similar, a portion contacting a mold inner surface and a portion not contacting the surface are generated. The non- contacting portion becomes a gap, and foaming gas passes through the gap to be released.  As a result, the way of the passage of the gas is improved remarkably to obtain a high precision roller stably.

Title: Driving device of timepiece rotary decoration
Inventor: OOKURA HIROO
IPC: G04B45/00
Filed: 1981-02-25
Abstract: PURPOSE:To avoid loosing the gracefulness of a rotary decoration of a watch although a spring of a high spring constant is used, by setting a gear and a pinion biting to each other between the spring which gives the reciprocal rotary movement and a driving shaft. CONSTITUTION:A driving shaft 6 has the reciprocal rotary movement with a certain cycle by the function of a spring 21 and via a sector gear 15 and a pinion 14. This rotary movement is kept on with supply of energy owing to a magnetic coaction of driving magnets 8 and 8 plus a driving coil 12. Thus a rotary decoration of a proper design which is mounted to the shaft 6 is driven with a reciprocal rotary movement. The inertia efficiency of the shaft 6 increases with such constitution, and therefore a spring having a high spring constant can be used for the spring 12 to reduce the breakdown of the spring with the simple handling and assembly.

IPC: B60R22/34
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To facilitate the control of meshing a pawl with the ratchet tooth of a frame. SOLUTION: A retractor meshing mechanism for obstructing the rotation of a shaft for a frame is installed eccentrically for the shaft and also rotated along with this shaft and provided with a movable pawl 7 onto the meshing position with the ratchet tooth of the frame.
