IPC: H04N5/08
Filed: 1988-12-22
Abstract: PURPOSE:To eliminate a trouble changing over a switch by providing two monostable multivibrators whose one has a large time constant and the other has a small time constant and one OR circuit and automatically switching the synchronizing signal from an internal synchronous signal to an external synchronous signal simultaneously with the input of the external synchronous signal.

This DC voltage value is used as the reference value of a voltage comparator 3 after being minutely controlled by a resistance voltage divider 4. The output of the voltage comparator 3 and the external synchronous signal are inputted to monostable multivibrators 6 and 7 having relatively small time constants. Thereafter, outputs of these multivibrators are inputted to an OR circuit 8 to finally obtain the synchronous signal. The circuit part consisting of two multivibrators 6 and 7 and the OR circuit 8 practically functions as a manual switch in a conventional device.

Title: Semiconductor integrated circuit
Inventor: INUZUKA TERUO
IPC: H03M1/76
Filed: 1988-12-21
Abstract: PURPOSE:To eliminate the effect of a potential drop due to a parastic resistance by dividing a potential by means of the resistance, in a circuit, where one divided potential is selected by means of a switch, wiring two lines from the divided resistance independently to the external pins of a package, connecting one line to the output of a arithmetic amplifier, and connecting the other line to an inverted input. CONSTITUTION:The potentials of nodes A and B are equally divided by resistances 1 to 4 having the same value, and fetched through a switch group 6 to 11 to an output VC0 by control input signals 14 and 15. Further, the two independent lines are wired from the node a to the inverted input and output of an arithmetic amplifier 20, and a normal input is fetched to an external pin as a REFP3 input terminal 30. In such a circuit, the arithmetic amplifier 20 constitutes a feedback loop. Since the inverted input of a parastic resistance 22 is the high input resistance, the potential hardly drops. The normal and inverted inputs of the arithmetic amplifier are approximately at the same potential. Consequently the REFP3 terminal 30 and a REFP2 terminal node A are at the same potential, and they are not affected by the parastic resistance. An arithmetic amplifier 21 is not affected in the same way.

Filed: 1991-12-09
Abstract: PURPOSE:To enable the easy formation of a glass film good for substrates consisting of silicon, etc., by sintering a metal alkoxide in a specific heating stage, thereby forming a porous glass layer. CONSTITUTION:The metal alkoxide is heated to evaporate and an inert gas is introduced as a carrier gas therein to introduce the gas of the metal alkoxide into a reaction tube.

The substrate 21 is placed in the reaction tube and the thermally decomposed oxide is deposited thereon. The flow rate of the carrier gas is controlled at this time, by which the thickness and compsn. of the film can be controlled. The substrate 21 deposited with the oxide is sintered by heating to form the porous glass and further, the substrate 21 is heated by a gas burner to melt the porous glass, by which a glass thin film 23 to constitute the waveguide is formed. Namely, this method is a simple method of sintering the substrate to the extent of forming the porous glass layer and melting the layer by heating and, therefore, the inexpensive mass production is possible.
