Title: Picture clock generating circuit
Inventor: KIMIZUKA JUNICHI
IPC: H04N1/113
Filed: 1988-07-15
Abstract: PURPOSE:To utilize a signal, whose frequency is same as that of a picture clock signal, from an original signal source as the picture clock signal by executing trigger synchronization to the signal of a prescribed frequency, which is supplied from a voltage control oscillator, with a horizontal synchronizing signal to be inputted. CONSTITUTION:When a prescribed original signal 1a is outputted from a crystal oscillating circuit 2, the signal is divided to be 1/m by a divider 3 and the divided original signal 1a is converted to a voltage signal 4a by an F/V converter 4. On the other hand, a clock signal 8a of the same frequency as the signal 1a is outputted from a voltage control oscillator 8 to an output terminal 11. At such a time, a divider 7 outputs a dividing picture clock signal 7a, for which the signal 8a is divided to be 1/m, to an F/V converter 6. The signal 7a is converted to a voltage signal 6a by the converter 6 and outputted to an amplifier 5. Difference between the signals 6a and 4a is amplified by the amplifier 5 and a differential signal 5a is outputted to the oscillator 8. The oscillator 8 controls an input voltage so that the signal 5a can be 0 and executes feedback control to the frequency of the signal 8a. Then, a synchronizing signal BD and the signal 8a are synchronized.

Title: Holding circuit for telephone set
Inventor: AKIBA TOSHIO
IPC: H04M1/80
Filed: 1986-07-25
Abstract: PURPOSE:To surely eliminate the disabling of an incoming call due to the capture of a telephone line, by providing a current limiting element which supplies a trigger current to a thyristor, and the gate of the thyristor. CONSTITUTION:By operating a holding switch in off-hooking, the trigger current is supplied to the gate of the thyristor SCR through a turned ON contact MS<1>, a contact HS<2> being turned ON, and a TR Q as the current limiting element, and the thyristor is turned ON, and a DC loop through a TKC3, and a contact MS<2> is closed, therefore, the ON state of the thyristor can be maintained by a loop current even by an on-hook operation, and a holding state is set. The thyristor SCR can maintain an OFF state, and the DC loop is not closed, even when the holding switch is set at an operating state accidentally in offhooking, because the contact HS<2> is turned off, and the trigger current is not supplied to the gate of the thyristor SCR. Also, when an opposite side performs the on-hook during the ON state of the thyristor, an exchange interrupts a loop current transiently, therefore, the thyristor recovers to an OFF state and cancels the holding state automatically.

Abstract: PURPOSE:To raise the operation speed and reduce the current consumption by using plural MOSFETs connected in parallel whose gates individual bit signals or their inverted signals of an address code are applied selectively and taking out a word line from the connection point between these MOSFETs and an MOSFET consisting of a transistor of the intrinsic mode. CONSTITUTION:Since an MOSFET12 is the intrinsic type, the potential of a word line 13 is higher than the level of a connection point (a) only by 0.2V, and the signal on the word line 13 is ''0'' practically. When the address code which selects the word line 13 is applied, ''0'' is applied to all gates of MOSFETs 7, and they are all turned off. At this time, a parasitic capacity exists hardly at a connection point (c), and the current which charges the large capacity of the word line 13 is not flowed by the action of the MOSFET12, and therefore, the potential at the connection point (c) is raised in a high speed with a minute current flowed through MOSFETs 9 and 10.

Title: Independent square tank of liquefied-gas tanker
Inventor: MOTOAMI KAZUMICHI
IPC: F17C3/00
Filed: 1984-08-25
Abstract: PURPOSE:To permit designing of the antifatigue strength of all the welded joint parts by one S-N curve including that for a basic material by designing the welding by obtaining the fatigue breaking strength on the basis of the stress concentration coefficient Kt at the welding stop edge part of the welded joint parts between members. CONSTITUTION:When a rated stress deltaN is applied onto a lateral plate 7, the stress distribution is shown by a numeral 10, and the stress for the part of the lateral plate 7 which is not welded is equal to the rated stress deltaN, but stress concentration occurs in the vicinity of an upper edge part 9, and the max. stress deltaN acts at the stop edge part 9. Therefore, when the stress concentration coefficient at the stop edge part 9 is represented by Kt, the following relation establishes Kt=deltaL/deltaN. When welding is performed free from restriction, welding cost can be cut, but Kt value increases, and the increases of the thickness of the plate become necessary. Therefore, the total cost can be cut by selecting Kt at a proper value, for example 3.0 or less.
