Title: Image forming apparatus and image forming unit with an improved phase adjustment means
Inventor: YORIFUJI TAKAO
IPC: G03G15/00
Filed: 1998-07-27
Abstract: A motor starts its rotation, and a clutch is operated to drive both of a first driving force transmission system for color printing, including drum gears, and a second driving force transmission system for monochrome printing, including a drum gear.  The clutch is disengaged to stop the first system when a first sensor detects a mark on one photosensitive drum of the first system at the same time that a second sensor detects a mark on one drum driving gear of the first system.  Next, when a third sensor detects a mark on another photosensitive drum of the second system at the same time that a fourth sensor detects a mark on another drum driving gear of the second system, the clutch is reengaged. Consequently, positionings of all the photosensitive body drums (drum gears) for color printing to the photosensitive drum (drum gear) for monochrome printing are performed without causing positional differences by inertia at the time of stop.

Abstract: This invention discloses the concept of incorporating a radioactive agent and various dyes to enhance lymphatic drainage, sentinel and lymph nodes. The use of a gamma emitting radionuclide such as Tc-99m allows the localization of the lymph node(s) that allows the surgeon to initially plan the surgical procedure. On the day of the study the radiopharmaceutical may need to be injected imaged and with the skin marked externally to assist the surgeon in locating the node during surgery. In order to facilitate the surgical probe a gamma detecting surgical probe can assist in providing the relative location of the node. This procedure has been found to be useful, however it has often been difficult utilizing this procedure to find all of the nodes. This invention would incorporate the use of a radioactive probe with a dye, the addition of the dye into the particles would allow the physician to more rapidly identify lymphatic channels, sentinel and other node(s) and allow them to be excised which would dramatically reduce the surgical time for the patient.

Inventor: CHANG HAK SOO
IPC: G01F1/66
Filed: 1999-07-30
Abstract: A conventional flow velocity measuring apparatus constituted as an important element of almost flowmeter is subject to operate based on an ultrasonic transmitting time difference method, but it causes the larger measuring error of the ultrasonic transmitting time, because the intensity of the ultrasonic pulse is severely pulsated at the receiving point due to the fluid sate under the condition of transmitting and receiving the ultrasonic pulse, the concentration change of suspension particles, etc.   A flow velocity measuring apparatus is to measure an ultrasonic transmitting time, transmitting and receiving ultrasonic continuous sinewave frequency-modulated in turn to time, in which one frequency discriminator detects the moment that a frequency of the ultrasonic beam is modulated upon the transmitting and receiving. Therefore, the error caused due to the detecting delay time is removed, because one frequency discriminator detects the receiving and transmitting signals, and the ultrasonic transmitting time measuring error is prevented, even through the amplitude of the receiving signal is severely pulsated. The flow velocity :measuring apparatus can be effectively used in an ultrasonic flowmeter for a larger calibration pipe and a larger river or sluice open channel.

Title: Pipe moving method, apparatus and system
Inventor: PETING ROBERT G
IPC: B22D13/10
Filed: 1999-08-05
Abstract: A system, apparatus and method are disclosed for moving an elongate object such as a pipe between lowered and raised positions, preferably while rotating the object to maintain its shape. The system and method use two apparatuses, an upender and a downender for moving the pipe between lowered and raised positions. The upender tilts a lowered pipe received from a casting machine to the raised position and places the raised pipe on a support station. The pipe is rotated while on the upender through at least part of the range of travel. The upright pipe on the support station may be moved through an annealing furnace and then the downender may lift the pipe from the support station and tilt it downward toward the horizontal while rotating the pipe through part of the range of travel. The lowered pipe is then pushed off of the downender by kick off arms.  Each apparatus has two different support systems for supporting the bottom end of the pipe, one support system being operable while the pipe is rotating and the other being operable while the pipe is non-rotating. A stabilizer is provided on each apparatus to prevent the pipe from tipping over as it is being tilted and moved onto and off of a support station. Rollers and roller drive mechanisms are provided on both apparatuses so that the pipes may be selectively rotated. Drives are also provided for moving the upender and downender apparatuses horizontally toward and away from support stations.

Title: Cleaning and finishing a ceramic mold
Inventor: SACHS EMANUEL M
IPC: B08B3/10
Filed: 1993-11-22
Abstract: A technique for removing loose powder from the interior surfaces of a ceramic mold made using layer manufacturing processes, such as three-dimensional printing processes. The interior of a mold can be filled with water which is boiled and the particles are entrained in the flow caused by the boiling liquid. Alternatively, fine particles are introduced into the mold and agitated in the mold to dislodge the particles and the powder so that they can be poured out of the mold. Such technique tends also to remove the surface finish of the mold. Any of the particles which remain can be dissolved in a liquid and removed in the liquid from the mold. Further, the surface finish of the mold can be improved by casting a slip of fine particles on to the surface to form a generally level, and preferably non-conformal, coating on the surfaces.
