Title: Automatic gain control circuit
Inventor: MINAMOTO TSUNESUKE
IPC: H03G3/30
Filed: 1982-02-17
Abstract: PURPOSE:To obtain an AGC circuit which has superior transient response characteristics to an instantaneous excessive input by performing gain control so that the output level of a variable gain amplifier is stabilized, and leading out the output of the variable gain amplifier or amplitude limiter as an output signal. CONSTITUTION:A negative feedback circuit is equipped with the amplitude limiter 13 to perform control so that the gain control voltage (output of gain control signal generating circuit 7) applied to the variable gain amplifier 4 does not exceed a prescribed value. Then, no excessive signal is inputted to the feedback circuit of the AGC circuit. Consequently, the output of the AGC circuit when a signal rising abruptly is inputted has a minimum level in rising less than when no amplitude limiter is provided and level suppression of time succeeding it is less. Therefore, a fast return to a stationary state is obtained in case of an instantaneous excessive input to improve transient response characteristics.

Title: Molding method of resin molded product
Inventor: OSUGI MASAKATSU
IPC: B29K105/06
Filed: 1990-02-02
Abstract: PURPOSE:To secure sufficiently adhesive strength between a strength member and molded product main body in the case of insert molding of a resin molded product possessing the strength member, by a method wherein at the time of the insert molding, an expected contacting sphere of a coating layer is softened by heating the same by electrifying a mesh member. CONSTITUTION:At the time of formation of a coating layer 20 over a knuckle 10, a mesh member 22 where a large number of through holes are formed and the same possesses electrical conductivity is laid into the coating layer 20 so that a part of the mesh member 22 is exposed from the coating layer 20 in an expected contacting sphere with a parison 16 on the outside of the coating layer 20. At the time of blow molding after that, the mesh member 22 is electrified and the expected contacting sphere of the coating layer 20 is softened by heating. Then a molding material constituting the parison 16 is agitated at the time when the same passes through the through hole of the mesh member 22 and it becomes that a glass fiber 18 in the same is entered into the softened coating layer 20. With this construction, a clear boundary surface is not left behind between the coating layer 20 and a molded product main body 12a. Therefore, continuity from a view point of strength can be given between both the coating layer 20 and molded product main body 12a. In other words, adhesive strength can be secured sufficiently.

Title: Detecting device for minimum remaining quantity of liquid in vessel for liquid
Inventor: TAKAHASHI TAKAO
IPC: G01F23/62
Filed: 1980-02-28
Abstract: PURPOSE:To enable sure detection of the state that the remaining quantity of liquid turns minimum by a constitution wherein a shielding member which is made to act by a magnet provided in a float indicating the height of a liquid level is arranged below a liquid reservoir part formed at the bottom part of the vessel and thereby a detecting means is made to operate. CONSTITUTION:When liquid L is taken out from the vessel 1 and reduced to the remaining minimum quantity filling only the inside of the liquid reservoir part 2, the float 11 lowers down into the liquid reservoir part 2, and as the result, the shielding member 12 is elevated by the attraction of the magnet 15 inside the float 11 and is made to contact with the lower surface of the liquid reservoir part 2. Under the condition, a gas jetted from a nozzle 14 strikes against the shielding member 12 and the flow thereof is checked thereby. Therefore, a gas of low pressure supplied from a supply pipe 17 of a detector 13 flows across a slit 19 into a returning pipe 18, which results in the rise in pressure inside the returning pipe 18. By a signal generated from detection of the rise in pressure inside the returning pipe 18, it can be known that the remaining quantity of liquid inside the vessel 1 turns minimum.

Title: Cam, dummy coincidence line chain, and core cell used in the cam
Inventor: SCHULTZ KENNETH JAMES
IPC: G11C15/04
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To enable a memory to consume a small power while searching contents of the whole of a large-capacity reference memory CAM simultaneously, by providing many coincidence lines for every one physical row and performing a two-dimensional decoding to achieve rational aspect ratio for the memory. SOLUTION: Core cells 210 belonging to a certain word line are connected to the coincidence line 212 of the word line with logical NANDs. Core cells 210 of respective words are chainingly connected in respective corresponding coincidence lines 212. The coincidence lines 212 transit downward only when all bits being a half word equals to reference data. Consequently, the circuit of grounding path for coincidence lines becomes a close when all bits coincide with the reference data in serial coincidence line chain. As a result, transitions are generated in a small number of coincidence lines in a searching operation. That is, one transition is generated every noncoincidence in the conventional practice but one transition is generated every one coincidence in this memory. Thus, the length of the NAND chain is shortened by bisecting the word and a speed is increased.
