Abstract: Disclosed is an apparatus of manufacturing a pipe-shaped insulator, wherein a thin fiberglass mat is coated, at a surface thereof, with a binder (adhesive) and is press-wound on a forming roller, so as to manufacture a pipe-shaped insulator having a predetermined thickness and a predetermined diameter. The apparatus includes a mat feeding roller, a plurality of fiberglass mat transportation rollers, a coating roller to coat a binder over a surface of the fiberglass mat, a forming roller on which the fiberglass mat, coated with the binder, is wound in plural times to form a pipe-shaped insulator, a squeeze roller disposed parallel to the forming roller, a pressure regulator to press the fiberglass mat, an encoder to measure a transported length of the fiberglass mat, a cutting unit to diagonally cut the fiberglass mat, a control system, a sensor, and a plurality of drive motors and power transmission members.

Abstract: Provided is a mask apparatus for skin beauty care using light. The mask apparatus includes a face mask that is configured to be placed on a human face, a light irradiation unit that is configured to irradiate light into a face of a user wearing the face mask, a light irradiation driving unit that drives the light irradiation unit, a controller that controls the light irradiation driving unit according to an operation signal of the operating unit, and a vibration sensor that senses external vibration or impact applied to the face mask, wherein, when a sensing signal instructing the light irradiation unit to be driven in an ON/OFF mode is received from the vibration sensor, the controller controls the light irradiation unit to be activated according to the sensing signal.

Abstract: A baggage lock device to halt rotation of caster wheels as the handle is retracted, and allow the wheels to move as the handle is pulled out. The device has a receptacle with a handle extendable to be pulled put. A wheel halting mechanism has a traction cord inhibiting wheel rotation by a force pressed against the wheel as operation of an operation mechanism is transmitted via a pulling force transmission mechanism having a pulled wire, a brake pad, a linking member, and means for restoring the position of the operated elements.”.

Abstract: A restarting device of a pump change-over valve in a pump is provided, in which the pump includes; a pump main body 1 and a change-over valve 2. The change-over valve 2 is provided with a pair of pressure chambers 31 and 32 formed at respective ends on the back face sides of a valve body 23. The driving fluid is supplied into the chambers to induce a pressure difference to switch the direction of movement of the valve body 23. Also, the pump main body 1 is provided with a balancing valve 49 whose end portions 49A and 49B face driving chambers 4A and 5A, respectively. If the change-over valve 2 malfunctions and the pressures in the two driving chambers 4B and 5B are balanced, the balancing valve 49 is held in an intermediate position and will then induce a pressure difference between the two pressure chambers 31 and 32.

Abstract: A diaphragm pump is provided with a diaphragm defining a pump chamber and a drive chamber in the pump housing, a driving fluid is supplied to the drive chamber and a pump fluid is expelled from the pump chamber. The diaphragm pump is provided with pressure control means which, when the pressure in the pump chamber surpasses the pressure in the drive chamber neighboring the pump chamber across the diaphragm, controls the pressure of the driving fluid based upon output signals from pressure sensors in such a manner that the pressure in the fluid chamber will become higher than the pressure in the neighboring drive chamber. This makes it possible to prevent a diaphragm reversal phenomenon, wherein a diaphragm that should expand toward the pump chamber contracts toward the drive chamber instead during reciprocation of the diaphragm.

Abstract: A diaphragm assembly has a center disk in which use of a metal member is not required. The center disk comprises first and second center disk members, made of resin, embracing a resin diaphragm between them. The first center disk member has an inwardly directed inner flange on an inner peripheral wall defining a resin charging space, and the second center disk member comprises a resin-molded body, formed by charging a resin, and has an outwardly directed outer flange. A portion of the diaphragm is clamped between the inner flange and the outer flange.
