Title: Insert molding connector
Inventor: SAWADA TAKASHI
IPC: H01R43/24
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To carry out insert molding without causing deformation of a terminal metal fitting. SOLUTION: A widening part 5 of a planar circular arc shape is formed in a portion corresponding to a gate 12 in a terminal metal fitting 1, and an opening 7 is formed in the widening part 5. When the terminal metal fittings 1 are contained in a cavity 11 of a molding die 10, the terminal fittings 1 are arranged back and forth, and are contained in a position where a circular arc-shaped face 8 on the bulge side of the widening part 5 is oriented to the gate 12 at the front of the gate 12. Synthetic resin ejected from the gate 12 passes through the opening 7 as shown by an arrow, and is guided in the circular arc-shaped face 8. The cavity 11 is charged with the synthetic resin while flowing to both sides in order that a housing is formed.  Although the terminal metal fitting 1 corresponds to the front of the gate 12, the ejected synthetic resin hardly meets with resistance and circulates through the cavity 11. In addition, the rigidity of the widening part 5 is enhanced to prevent the terminal metal fitting 1 subjected to resin pressure from being flexed and deformed.

Title: Automatic gain control circuit
Inventor: HAYASHI YUTAKA
IPC: H03G3/30
Filed: 1988-02-05
Abstract: PURPOSE:To clearly remove the noise of an input signal by adding a resistance to the emitter of a second transistor(TR) in an AGC circuit to have a current mirror circuit. CONSTITUTION:The input signal from an input terminal VIN is inputted through an amplitude/voltage converting circuit A/V to the base of a TR Q1. A current i1 to be approximately equal to a collector current to flow according to the base current of the TR Q1 is made to flow to the collector of a TR Q2. At the same time, a collector current i2 of a TR Q3 of a current mirror circuit 1 is also made to flow according to the base voltage of the TR Q1. At such a time, since the collector voltage of the TR Q2 is lowered by a resistance RE, the current i2 is made into a value larger than the current i1. By inputting the current i2 to the bases of TRs Q4 and Q5, even with the input signal VIN to be small, the current i2 of the current mirror circuit 1 is made into the large current, and it is inputted to a non-inverting amplifier circuit A. Consequently, since a gain is made large, simultaneously, quick and constant, the noise of the input signal can be clearly removed.

Title: Oxidation scale preventive agent for arc welding
Inventor: KOMATSU TADAO
IPC: B23K35/36
Filed: 1989-02-03
Abstract: PURPOSE:To prevent the generation or oxide scale in arc welding by hydrolyzing tetraethyl silicate in a low boiling solvent and compounding a lithium compd. which mingles uniformly with water therewith and using the resulted compsn. of the hydrolysis reaction as an effective component. CONSTITUTION:The tetraethyl silicate is an alkoxy metal compd. and is colorless transparent liquid. This compd. is polymerized to form a high-polymer compd. by making deethanolization when the compd. is subjected to the hydrolysis reaction by adding the water and catalyst thereto. Not the product resulted from the mere reaction by the water and catalyst in the low boiling solvent but the compsn. obtd. when the reaction is effected with the solvent system mixed with the lithium compd. acts effectively to prevent the oxide scale of arc welding. The effect is slightly inferior but the oxide scale is effectively prevented even when the lithium compd. is compounded therewith after the hydrolysis reaction of the tetraethyl silicate. The generation of the oxide scale is effectively prevented when this agent is applied on a base metal.
