Patent JP-S6363211-A (JP)
Title: Active filter
Inventor: KABASHIMA AKIRA
IPC: H03H11/04
Filed: 1986-09-03
Abstract: PURPOSE:To easily cope with the modification of gains after ICs are manufactured by correctly obtaining a band-pass output only by setting the resistance ratio of two operational amplifiers, setting said ratio within a prescribed value and increasing gains according to the ratio of capacitors. CONSTITUTION:A feedback circuit 25 is constituted of a resistance 26 whose one and other ends are connected to a reference potential and the inverted input terminal of an integration circuit 20 respectively, and a resistance 27 whose one and other ends are connected to the inverted input terminal, of the integration circuit 20 and an output terminal 29 respectively. The value of the resistance 27 is larger than that of the resistance 26, and the band-pass output can be obtained at the output end of an integration circuit 16 accordingly. Where the resistance value R1 of the resistance 26<the resistance value R2 of the resistance 27, the gain H02 of an output from a BPF rises, whereas the gain H03 of an output from an LPF subsides. Thus, even if the resistance ratio is held in order to prevent variance when stuff is made into ICs, high gains are attainable only by raising the ratio of the capacitors slightly because the gain H02 of the output from the BPF is obtained by multiplexing the ratio of the resistances and that of the capacitors. The value of the capacitor can be easily modified through metal alternation after ICs are manufactured.

Title: Method for preventing adhesion of barnacle
Inventor: YAMAMOTO HISASHI
IPC: A01N43/84
Filed: 1994-08-31
Abstract: PURPOSE: To provide a new method for preventing the adhesion of barnacles, useful as an antifouling measure against the biological staining of sea with the barnacles causing large damages to shipping industry and fishery. CONSTITUTION: The method for preventing the adhesion of barnacles comprises applying a calmodulin-inhibiting agent to the cypris larva of the barnacle to raise the cypris larva to the imago of the barnacle without passing through the process of the adhesion. The calmodulin-inhibiting agent is suitably amitriptyline of formula I and imipramine of formula II. Follows are estimated. When the calmodulin-inhibiting agent is allowed to act on the cypris larva, the expression of a Ca<2+> function required for biological phenomena such as cell division and secretory phenomenon is inhibited. The function of an adhering organ playing an important role on the adhesion process of the barnacle is thereby inhibited, and the barnacle is raised to the imago without passing through the process of its adhesion.  The practical application of the calmodulin- inhibiting agent is performed by spraying the calmodulin-inhibiting agent on a sea area to inhibit the adhesion of the barnacle, applying capsules containing the barnacle to the sea area to gradually release the barnacle, or returning the cypris larva preliminarily treated with the calmodulin-inhibiting agent to the sea area.
