Title: Automatic switching system for communication line
Inventor: KOO HIDEO
IPC: H04B1/74
Filed: 1992-02-04
Abstract: PURPOSE:To automate the constitution of a by-pass route in the case of a line break and shorten a telephone call failure time by providing each key station with a detector which can detects a break of a monitor signal and a switch. CONSTITUTION:When an in-use communication line 4 is normal, a speech from a controller 1 is sent to a high-order key station 14 through the switch 2 together with a line monitor signal generated by an oscillator 3, sent to a distributor 8, and then sent to a low-order key station through an amplifier 9 for transmission and the switch 2 again. If the in-use line 4 between some key stations is disconnected, the line monitor signal is cut off on the lower-order side than the disconnection position, so the line monitor signal detection of the switch 2 is put in operation, and a switching relay operates to switch the in-use line to the side of a stand-by communication line 5. Consequently, the higher-order key station uses the in-use communication line 4 and the lower- order key station uses the stand-by communication line 5 on the basis of the disconnection point as a border, so that the whole line between a commanding person and an on-vehicle station conductor is secured.

Inventor: UENO TOSHITAKE
IPC: H04N5/335
Filed: 1986-03-05
Abstract: PURPOSE:To prevent the occurrence of afterimage phenomenon and to make the photoelectric transducing characteristic linear by irradiating a light to a photoelectric transducing cell of a photoelectric transducer requiring the refresh. CONSTITUTION:A light is irradiated to a full photoelectric transducing cell from a power supply 60 when a pulse signal phil rises and an electron-positive hole pair is generated in the cell 20. Since the conduction electron flows externally through a collector electrode, only the positive hole is injected in a base region to boost the base potential. When pulse signals phiVC and phirs rise next, transistors TRs 25, 25', 25'' are turned on and TRs 30, 30', 30'' are turned on and respective vertical lines are connected to ground. When a pulse signal phif rises succeedingly, a refresh positive voltage pulse is fed to horizontal lines 21, 21', 21'' and simultaneous refresh is applied to the cell 20.

Abstract: PURPOSE:To place a sea bottom signal in the lower half part of a recording display band, and also display a information of a region above the sea bottom, by transferring the sea bottom signal, which is detected from the receiving signal of ultrasonic pulses, to a prescribed position when this signal is outside a vertical display range. CONSTITUTION:A sea bottom signal is detected from the receiving signal of ultrasonic pulses and is stored in lines (x)-(n) of a storage part and is displayed. In this case, when the sea bottom signal deviates upward from a display range, for example, when sea bottom pulses exist for output values (x/2)-(x)[corresponding to lines (x/2)-(x) of the storage part]of a counting circuit 13, a numeric value (x-2)/2 generated from a numeric value generating circuit 29 is added to the current numeric value in a circuit 31, and the addition result is led into the circuit 13, and the sea bottom signal is loaded from a line (n-x)/2 at the next transmission time. When sea bottom pulses exist for output values 1- (x/2-1) and deviates downward from the display range, the sea bottom signal is loaded from a line (n+x)/2 (this numeric value (n+x)/2 is generated by a numeric value generating circuit 30) at the next transmission time. Thus, the sea bottom signal is placed in the lower half part of the recording display band, and therefore, detection information in regions above the sea bottom are recorded and displayed together.

Title: Solid-state image pickup element
Inventor: NAKAMURA SATOSHI
IPC: H04N5/341
Filed: 1990-02-28
Abstract: PURPOSE:To surely attain shared transfer by transferring a charge between horizontal charge transfer sections in a way that levels of transfer signals of different phases with respect to areas of two horizontal charge transfer sections opposite to each other are both changed at a lower speed than that at high speed transfer. CONSTITUTION:The high speed transfer of horizontal registers 4, 5 transferring a charge in the horizontal direction is finished at a time t0 and transfer signals PHIH1, PHIH2 are both brought into a high level. A signal PHIVH fed to a gate 9 between a storage section 3 and a horizontal register 4 changes from a low level to a high level at a time t1. Then the levels of the transfer signals PHIH1, PHIH2 being at a high level for times t2-t3 are both transited at a low speed and reach a low level at the time t3. Since the levels of the transfer signals PHIH1, PHIH2 are transited at a low speed for the times t2-t3 in the case of the transfer between the horizontal registers 4 and 5, the phase margin is increased and the shared transfer is ensured.
