IPC: H04N5/91
Filed: 2000-04-07
Abstract: PROBLEM TO BE SOLVED: To simplify the processing of reproducing or deleting images obtained by continuous mode.

IPC: H04W56/00
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To improve the success rate for new call connection between a base station and a repeater. SOLUTION: In a PHS repeater 16, when a communication channel notified from the base station to be used for a new call has already been used by the existing call at the time of connecting the new call between the base station and the repeater, the existing call is shifted to another free communication channel by using a TCH switching procedure, and the new call between the base station and the repeater is connected by using the notified communication channel that is made free as a result of the shifting.  When the repeater 16 has two pieces or more communication equipment and the existing call to be shifted is also a call between the repeater and a terminal, a communication channel before and after shifting is selected so as to be equal other than the communication equipment, and in a TCH switching sequence, a synchronous burst signal for switch back is transmitted by using the communication channel of a shifting destination.

Title: Apparatus for detecting pressing force to optical part
Inventor: FUJIWARA SHIGERU
IPC: G02B6/24
Filed: 2000-04-19
Abstract: PROBLEM TO BE SOLVED: To prevent a pressure sensor from breaking even when a load not smaller than a load capacity is acted by an unexpected external force. SOLUTION: When one optical part 5B to be connected is pressed against the other optical part 5A held by a support 47A to face register each other, a pressure acting on the other optical part 5A is detected by the pressure sensor 109 via the support 47. At this time, the pressure sensor 109 is pressed to a forward end position by predetermined pressurization by a pressure sensor- supporting means 107 and is prevented from moving backward even if the pressure acts on the other optical part 5A so long as the pressure does not exceed the pressurization. The pressure acting on the other optical part 5A can accordingly be detected via the support 47.  On the other hand, if the pressure exceeding the pressurization acts on the other optical part 5A, the pressure sensor-supporting means 107 moves the pressure sensor 109 backward to prevent a pressing force exceeding the pressurization by a predetermined value or more from acting on the pressure sensor 109 and at the same time, a support stopper 101 blocks the support 47 not to move backward by a predetermined value or more.

Abstract: PROBLEM TO BE SOLVED: To provide a channel prediction which changes together with environments fluctuating at high speed by assuming that the channel linearly changes to a time and executing linear regression to a sample in a sampling window of a first signal component in a reception signal. SOLUTION: A frequency offset prediction value f"(t) is generated by a frequency offset predicator 10 by using a known signal component in a reception signal and is outputted together with a reception symbol r(t).

IPC: G01V3/10
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a proximity sensor that uses a common circuit to accurately discriminate the presence of an object independently of the type of material of the case of a coil. SOLUTION: A transmission coil 12 generates a magnetic flux to the outside of the case S, and the magnetic flux coupling with the coil itself is changed according to the proximity state of a metal made object to the transmission coil 12 and a reception coil 21. Then a comparator means 26 of a detection means 100 outputs the output signal according to the proximity state of the object to the coils 12, 21 to detect the object. When no object exists in the vicinity of the proximity sensor, a sensitivity setting circuit 24 adjusts the sensitivity level of the detection means 100 on the basis of the result of discrimination by a level discrimination means 27 in that state and a signal from a temperature detection means 28.  That is, in the case e.g. the case S covering the coils 12, 21 is made of a metal and the magnetic flux permeability is lower by the eddy current loss, the sensitivity setting circuit 24 increase the amplification factor of an amplifier circuit 23 and when the temperature is high and the eddy current loss in the metal is increased, the sensitivity circuit 24 increases the amplification factor.
