Abstract: PURPOSE:To easily and efficiently remove burs without giving a flaw to a product by intensionally make burs thick generated at the time of resin sealing by providing a resin pot to a metal mold. CONSTITUTION:A resin material pressurizingly sent from pot etc. passes a runner 9 and is sent to upper and lower cavities 7, 14 and is filled with the specified molding pressure. Since a resin is sent under a considerably high pressure, a resin overflows cavities into resin unwanted portion as burs and thereby the resin in the resin pot 12 and that in the cavities 7, 14 are connected. However, since a metal mold 8 is provided with a resin pot 12 and the burs generated stop at this pot. In other words, the resin passing a side of base 13 reaches the resin pot 12, where a pressure is rapidly lowered. Therefore, the  resin is promptly hardened. The hardened resin interfares migration of resin  sequentially flowing. Namely, burs are not generated at the area other than the  resin pot 12. Thereby burs can be easily separated from the products.

Abstract: PURPOSE:To improve in-phase voltage characteristics (CMRR) greatly by shielding a hold capacitor, and controlling the potential of the shield so that it follows up the ground potential of the hold capacitor and also wiring both terminals of the hold capacitor so that wiring impedance values at both terminals are equal to each other. CONSTITUTION:Drain-source resistances of FETs Q1 and Q2 of a shield potential control circuit SD vary according to the potential e1 of a plus-side signal line and the potential e2 of a minus-side signal line, and the potential of the shield SI is controlled in following-up to the ground potential of the hold capacitor Ch. Consequently, even when stray capacities C1 and C2 are present, there is no charge entering and exiting from the hold capacitor Ch through those capacities and CMRR is improve greatly. Further, the both-terminal wiring of the hole capacitor Ch is branched from wiring shown by a thick line while equal impedance Z1 is held. Therefore, variations of the hold capacitor Ch with impedance Z1 are suppressed for fast charging and discharging by the effect of the stray capacities C1' and C2'.
