Title: Optical transmission apparatus, optical receiving apparatus, and optical communication system, and transmission reception method therefor
Inventor: TAKAHASHI SHUICHI
IPC: H04B10/2507
Filed: 2002-10-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical communication system or the like wherein no strict adjustment of a pulse width is required for reducing the adjustment cost, easily configuring the system, and suppressing the power consumption.  <P>SOLUTION: The optical communication system 100 comprises: an optical transmission apparatus 10, an optical transmission medium 20; and an optical receiving apparatus 30, the optical transmission apparatus 10 is provided with an NRZ/pulse modulation circuit 12, and the optical receiving apparatus 30 is provided with a pulse/NRZ demodulation circuit 34. The optical transmission apparatus 10 generates a pulse signal S4 synchronously with a data transition point in an NRZ signal as a transmission signal and drives a laser diode by using the pulse signal to transmit an optical signal, and the optical receiving apparatus 30 recovers the NRZ signal synchronously with the received pulse signal S8. Since no strict adjustment of the pulse width of the transmission signal is required in this way, the adjustment cost is reduced, and since the width of the pulse signal is narrowed, the light emission amount of the laser diode is decreased to reduce the power consumption and to prolong the lifetime.  <P>COPYRIGHT: (C)2004,JPO

Title: Method and apparatus of determining and displaying helical artifact index
Inventor: TOTH THOMAS L
IPC: G06T11/00
Filed: 2002-10-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a means for deciding a prospect of an existence of an artifact in the reconstruction and visual display of an image for the evaluation of a scanning system by an operator.  <P>SOLUTION: The helical artifact index (HAI) is decided by processing a phantom image to be obtained (170, 340). Then, the HAI is displayed on a console for an operator (180, 40), if necessary (360), so that the operator can re-establish a scanning parameter or newly select a scanning protocol that generates a reconstruction image of a subject with a reduced artifact presence (390) when necessary. This invention eliminates the necessity on the part of the operator to recall a scanning profile that is apt to heighten the artifact presence when the operator is provided with the prospect as to the artifact presence.  <P>COPYRIGHT: (C)2003,JPO

Title: High-efficiency low temperature heat collecting panel and its heat transport system
Inventor: SATO HARUKI
IPC: F24S10/95
Filed: 2002-11-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a heat transport system efficiently using solar heat which is natural energy, a water supply system, a building environment control system for heating and air-conditioning, hot water supply, and the like, and a cooling device for electronic devices or the like.  <P>SOLUTION: When solar heat is applied to a heat collecting plate 101A, an operating fluid evaporates at a low temperature and moves as steam to a header 102B since the interior of the device is decompressed by a vacuum pump 105H. A bumping phenomenon occurs within a heat collecting plate copper pipe, and liquid and steam pushed out by the liquid move to the header. The liquid circulates from a header lower part to a heat collecting plate inlet, and the steam moves from a header upper part to a condenser 103C and is condensed by cooling water controlled in temperature in a circulating constant temperature vessel 104D. A condensate moves again to the heat collecting plate inlet, and the liquid is circulated. In this system, noncondensed gas in the device is exhausted, and the evaporation temperature of the operating fluid can be lowered close to the environmental temperature. Since the operating fluid is circulated in a comparatively low temperature state, heat loss to environment can be suppressed.  <P>COPYRIGHT: (C)2004,JPO
