Abstract: <P>PROBLEM TO BE SOLVED: To provide a system in which a communication call tariff is not charged to both a transmitting side and a receiving side for information of a life reaction sensor which is installed on a remote site, or emergency information via a telephone line.  <P>SOLUTION: When an in-house life reaction sensor on a remote site reacts, a call is automatically originated from an automatic call origination telephone apparatus installed in the house to a determined telephone number of "0120×××××". Since caller number notification services are offered from NTT (Nippon Telegraph and Telephone) East Corporation and NTT West Corporation to a recipient side computer beforehand, it can be recognized which house originates the call to the telephone number. By receiving the telephone number of "0120×××××", it can also grasped which sensor in the house provides the information. In that case, since the receiver computer sets a telephone line not in a speech mode but in a call mode, no communication tariff is charged. The call is cut off from the side of the automatic call origination telephone apparatus. In the case of emergency information in the house, operation is similar to said processing but when the telephone number of "0120○○○○○" is registered in the automatic call origination telephone apparatus, the receiver side computer can decide the emergency information from a receiving line.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: A method for continuously casting grain oriented electrical steel is disclosed. This method utilizes a controlled rapid cooling step, such as one using a water spray, to control the grain orientation in the finished product. The product formed not only has the appropriate grain orientation but also has good physical properties, for example, minimized cracking. In this process, after a continuously cast electrical steel strip is formed, the strip undergoes an initial secondary cooling to from about 1150 to about 1250° C., and finally undergoes a rapid secondary cooling (for example, by water spray) at a rate of from about 65° C./second to about 150° C./second to a temperature of no greater than about 950° C.

Abstract: An enhanced radio network controller (RNC) node of a radio access network stores context information for a user equipment unit which is in a Connected Mode, and initiates a cell update-prompting message which is transmitted the user equipment unit. The stored context information is used by the context-enhanced radio network controller (RNC) node for addressing the cell update-prompting message to the user equipment unit. After the user equipment unit (which is in its Connected Mode) performs the prompted cell update procedure, such user equipment unit (UE) can be paged with a conventional paging message. The invention with its context-enhanced radio network controller (RNC) node is particularly suitable to user equipment units which are in a critical state of the Connected Mode, such as (for example) either a CELL_PCH state or a URA_PCH state of the Connected Mode.

Title: 車両の静止状態から移動状態への移行に応答するタイヤ圧モニターシステム
IPC: B60C23/02
Filed: 2003-01-14
Abstract: タイヤ圧モニターシステムは、各タイヤ圧モニターセンサーからの定期的な送信信号をモニターする。特定のセンサーが通報し損なうと、カウンタがインクリメントされる。カウントが限界値と比較されるが、低い限界値は移動中の車両に対して、また、高い限界値は静止状態の車両に対して設定されたものである。カウントが限界値を超えると、特定の送信機が故障状態にあると判定される。車両が静止モードから移動モードへ移行すると、カウントが限界値と比較され、２つの限界値の間にあれば、制御装置が移動モードでの動作をモニターする前にそのカウントが低い数にリセットされる。このように、車両が静止状態から移動モードに移行する時に、２つの限界値の間に差があることにより送信機が故障状態にあると不正確に判定されないようにすると、送信機が故障状態にあると不正確に識別されることが減少するかなくなる。

Abstract: The present invention provides a method of detecting non-apoptotic DNA in clinical samples. In particular there is provided a novel screening methodology for the detection of colorectal carcinoma. Cancer results from genetic mutations which result in uncontrolled and unregulated cell growth. Apoptosis does not occur in cancerous cells and thus the DNA remains unfragmented. Colorectal cancer results from mutations which occur in varying sites of the DNA. Accordingly there is no ubiquitous marker specific to colorectal tumour cells. The present invention provides the finding that the presence of specific fragments of DNA can be used to diagnose cancer irrespective of the point of DNA mutation. The method includes the step of obtaining a suitable sample, extracting the DNA therefrom and then amplifying and separating the fragments by electrophoresis in order to detect the presence of banding which is indicative of non-fragmented DNA derived from cancerous cells.

Title: Driving method for liquid droplet discharging head, liquid droplet discharging head and liquid droplet discharging apparatus
Inventor: ISHIYAMA TOSHIKI
IPC: B41J2/045
Filed: 2004-01-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a liquid droplet discharging head which can take countermeasures against a viscosity increase of ink at a low lost, and to provide a liquid droplet discharging apparatus and its driving method.  <P>SOLUTION: A solvent of the ink near nozzles evaporates between dischargings of ink droplets and an ink concentration becomes high, which sometimes causes the viscosity increase and affects ink discharge characteristics. Therefore, such a pulse that generates near the nozzles a flow velocity of a level whereby ink droplets are not discharged is applied as a spare waveform to piezoelectric elements, thereby stirring the ink near the nozzles. Thus the viscosity increase is suppressed. The axis of abscissa is a pulse width of the spare waveform when a natural period of a pressure chamber is made 1. The pulse width of the spare waveform is made not larger than 20% of the natural period or is made 80-125%. In other words, the ink can be stirred without discharging the ink droplets by the spare waveform if it is a pulse width of the range indicated by oblique lines.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
