Title: Orthodontic appliance
Inventor: TAKEMOTO KYOTO
IPC: A61C7/14
Filed: 1999-02-19
Granted: 2005-04-26
Abstract: When an orthodontic appliance is attached to the lingual side (back side) of teeth which is invisible from the outside, a large difference in level of the surface between adjacent teeth requires utilization of a wire bent in a complicated fashion. It has been found, however, that the difference in level between adjacent teeth is very small in a horizontal plane at a boundary between a crown and a root, thereby making it possible to draw a smooth envelope therealong. Based on this finding, with a view to placing a wire along such an envelope, a "lingual straight archwire" having a planar configuration comprising a simple curve and straight lines smoothly connected to ends of the curve and residing in a single horizontal plane and a bracket having a configuration suitable for the placement of the archwire are provided.

Abstract: A method and system for transferring telephone calls and data between computer programs in a call center. Flow connection modules associated with call center application programs allow data and telephone calls to be transferred from one computer program to another in the call center. The flow connection modules may be combined with a locator program such that the combination replaces the automatic call distributor ("ACD") in a call center. The flow connection modules enable development of modular call centers, allowing call center agent workstations to be easily increased or decreased. In operation, an application notifies its flow connection module that a call on a telephone in the workstation should be transferred to another application. The flow connection module establishes a data connection with a flow connection module associated with the other application. The flow connection module sends call-related data to the other flow connection module which then returns the telephone extension associated with the other application. The flow connection module requests a computer telephony interface ("CTI") link associated with a phone switch to transfer the call to the other application's telephone. The CTI link directs the phone switch to transfer the telephone call from the original application's workstation to the telephone of the other workstation. Having received notification of the transferred call, the other flow connection module informs the original flow connection module that the call has been successfully transferred, and the original flow connection module then disconnects the data connection.

Abstract: A dust-collecting device for a vacuum cleaner comprising a dust-collecting case which is fitted into a suction path extending from a suction nozzle to a motor fan and from which accumulated dust can be discharged by opening a bottom lid of the dust-collecting case, and a cylindrical filter fitted into the dust-collecting case. The filter is arranged to be rotatable, a spiral rib is formed at an outer periphery of the filter, and the device is equipped with a rotating means for rotating the filter. Dust which cannot be discharge by its own weight since it is in a compressed state can be pushed out through the spiral rib formed on the outer periphery of the filter by rotating the filter, so that dust accumulated within the dust-collecting case in a compressed state can be easily discharged.

Abstract: A tissue-protective device (16, 18, 20, 60, 66, 76, 86, 96, 110, 130) and a method for protecting tissue against abrasion by attaching a pair of mutually overlying membranous layers (26, 28, 122, 124) to an area of a tissue surface such as a person's skin with only the peripheries of the layers interconnected with each other, so that the layers can easily slip along each other. An absorbent pad (88, 98) may be placed between one of the layers and the tissue, and may be impregnated with medication to be delivered to the tissue being protected. A quantity of a lubricant can be contained between the layers. The device is thin, to avoid causing pressure when it is used in restricted spaces, as within one's shoe. The device can also be implanted internally as where tendons move along an implanted plate.

Abstract: A combination sight glass and optical sensor is provided in the housing of a hermetic compressor to provide effective visual inspection in addition to automatic sensing of the level of oil in an oil sump. A sight glass fitting is provided in the housing and has a first portion that extends outwardly from the housing and that is accessible from outside the compressor. An optical oil level sensing device is removably attached to the first portion of the sight glass with electrical leads extending outside the compressor for connection to a compressor controller. A prism or similar device is attached to the sight glass fitting intermediate the sump oil and the optical sensor. The sensing device includes a light source, a photosensitive detector, and an opaque member to prevent cross coupling between the light source and the detector. Should the oil level in the oil sump fall below a predetermined level, the optical sensor sends a low oil level signal to the controller which interrupts power to the compressor or generates an alarm or status signal. A technician may remove the optical sensor from the sight glass fitting and visually inspect the oil level by looking through the sight glass fitting and prism and into the interior of the compressor housing. One embodiment of the optical sensor will also provide a low oil level signal to the controller when the optical sensor is disengaged or removed from the sight glass.

Abstract: Gas turbine segmental ring has an increased rigidity to suppress a thermal deformation and enables less cooling air leakage by less number of connecting portions of segment structures.      Cooling air (70) from a compressor flows through cooling holes (61) of an impingement plate (60) to enter a cavity (62) and to impinge on a segmental ring (1) for cooling thereof. The cooling air (70) further flows into cooling passages (64) from openings (63) of the cavity (62) for cooling an interior of the segmental ring (1) and is discharged into a gas path from openings of a rear end of the segmental ring (1). Waffle pattern (10) of ribs arranged in a lattice shape is formed on an upper surface of the segmental ring (1) to thereby increase the rigidity. A plurality of slits (6) are formed in flanges (4, 5) extending in the turbine circumferential direction to thereby absorb the deformation and thermal deformation of the segmental ring (1) is suppressed.
