  • Publication number: 20110117805
    Abstract: Provided is a manufacturing method to prevent devitrification of a bulb in a high pressure discharge lamp used for a projector. The method is for manufacturing a high pressure discharge lamp which uses, as a light source, a bulb made of fused quartz and including a tungsten electrode, and which is horizontally installed when the lamp is driven for actual use. The method includes the step of initially driving the bulb with an optical axis thereof being set horizontally before the high pressure discharge lamp is shipped. In the initial driving step, the rotation angle around the optical axis of the bulb is offset by 45° or more and 135° or less relative to the rotation angle around the optical axis of the bulb when the lamp is driven for actual use.

  • Patent number: 4338777
    Abstract: When an open end spinning machine is stopped, a fiber supply to a spinning rotor is first stopped and thereafter, substantially simultaneously with stoppage of both a yarn take-up roller and a yarn winding roller, a yarn end is held by a yarn holding device at a time when it still remains in a region which undergoes the suction effect of a subatmospheric pressure produced in the spinning rotor. The spinning rotor is subsequently stopped. On starting, the holding of the yarn end by the yarn holding device continues even after restarting of the spinning machine until the subatmospheric pressure produced in the spinning rotor reaches substantially the same value as that produced during a normal spinning operation. Therefore, there is prevented any snarling phenomenon, resulting in a greatly increased success rate in the operation of connecting yarn ends on re-starting of the spinning machine.

  • Patent number: 4334403
    Abstract: An open end spinning machine includes a plurality of spinning units. Each spinning unit includes a first yarn breakage sensing device assuming a yarn sensing, operative position, in which it contacts the yarn, when the spinning unit is in a normal spinning operation and an inoperative position, in which it is not in contact with the yarn, when the spinning unit is in a transient condition either from or to the normal spinning operation, and a second yarn breakage sensing device assuming a yarn sensing position at least when the spinning unit is in the transient condition. Upon occurrence of yarn breakage when the spinning unit is in the transient condition, such breakage is detected by the second yarn breakage sensing device and the supply of fibers to the associated spinning unit is interrupted by the second yarn breakage sensing device.
