Title: Cordless telephone system capable of quickly establishing connection during call setup phase
Inventor: ORIKASA HIROMI
IPC: H04W84/10
Filed: 1991-04-23
Granted: 1995-02-07
Abstract: In a cordless telephone system, several speech channels are periodically scanned by a base station during a standby mode to detect idle channels from the scanned channels. In response to receipt of a call request from a cordless station or an incoming call from a switched telephone network, the base station transmits a channel indicating signal to the cordless station over a control channel indicating that the detected idle channels can be used as possible candidate channels, switches to a first candidate channel and waits for an end-of-switching signal from the cordless station until a prescribed period of time expires. On receiving the channel indicating signal, the cordless station switches to the first candidate channel and makes a channel check on it and transmits an end-of-switching signal if it determines that the first candidate channel is idle. If the end-of-switching signal is not received from the cordless station before the prescribed period expires, the base station switches to a second candidate channel. If the cordless station determines that the first candidate channel is busy, it switches to the second candidate channel and makes a channel check on it. If the cordless station determines that the second candidate channel is idle, it transmits the end-of-switching signal over the second candidate channel.

Title: Surface treatment device and process for a metal product layed in a reactive solution, particularly for the chemical cleaning or the galvanization of hot rolled metal sheets
Inventor: NOGUES MICHEL
IPC: C23G3/02
Filed: 1992-03-31
Granted: 2002-10-29
Abstract: Pickling or galvanising process according to which high-frequency vibrations are imparted to the sheet metal (1) travelling through an acid-filled trough; the device comprises at least one pair of electromagnets (2,3) arranged facing each other on both sides of the sheet metal (1), which are supplied with currents of the same frequency and each exerting a periodical attraction force on the sheet metal (1), the forces exerted by each electromagnet (2,3) being offset by  pi /2, with the result that the sheet metal (1) vibrates at a frequency which is twice that of the supply current. The vibratory power injected into the sheet metal is greater than the cavitation threshold of the reactive solution in the vicinity of the sheet metal, with the result that this cavitation and the vibrations imparted to the sheet produce fissures in the layer of scale and make it easier to attack with acid, which considerably shortens the time needed for pickling the sheet metal. <IMAGE>

Title: Metal retainer for quick connect tubing connector
Inventor: MCNAUGHTON JAMES
IPC: F16L37/098
Filed: 1992-09-14
Granted: 1999-07-20
Abstract: A  unique  retainer  is  disclosed  having  a  plurality  of resilient arms securing a tube within a housing bore.  The arms include a radially inner section having a pair of circumferentially extending braces which increase the strength of the arms.  The braces have axial ends which are bent radially outwardly and increase the strength of the arms, and also result in a more consistent, predictable buckling force for the retainer.  Arm bends are formed between the arm radially inner section and a radially outer section.  The axially outer bends of the braces are generally axially aligned with these arm bends, such that the bends provide a planer surface for positioning the retainer within the housing.   Also,  "bumps" are defined at a radially inner face of  the radially inner sections of the arms to create a high force resisting tube insertion.  The bumps are at an angle relative to a central axis that is greater than the angle of the remainder of the radially inner section of  the arms.   Thus,  the retainer arms may extend at a first angle which is relatively small relative to the axis and can provide a great force resisting tube removal, while the bumps are at the greater angle, and can provide a relatively great force resisting tube insertion.

Abstract: A logic function block having an output signal potential sensing function is substituted for each of logic function blocks of which fault conditions cannot be detected on the basis of predetermined input/output signal combinations for determining whether or not the semiconductor integrated circuit device operates correctly.  Probe lines and sense lines are connected only to the logic function blocks having output signal potential sensing function.  The probe lines are driven from a probe line driver, and a sense line receiver reads out signals on the sense lines.  Thus, without reducing fault detecting efficiency, the areas of an active region and a wiring region required for forming a fault detecting arrangement can be reduced.
