摘要： There is disclosed herein a ferroelectric liquid crystal electro-optical apparatus of the maxtrix type comprising a liquid crystal cell having first and second electrode substrates which include n striped line electrodes and m striped column electrodes, respectively, facing at right angles each other. A ferroelectric liquid crystal is put in therebetween so as to form n by m indication picture elements. Also included in the apparatus a scanning drive device adapted to supply a scanning signal and a data signal to the n striped line electrodes and the m striped column electrodes, respectively. The ferroelectric liquid crystal shows three stable states in accordance with an application voltage and has a light transmittance with a hysteresis sufficient to a dynamic drive in accordance with increase or decrease in the application voltage in a predetermined voltage range. The scanning drive device produces a first combination signal as a signal running to variation from a voltage below a refernece voltage in a predetermined one polarity voltage range to a voltage above the reference voltage and produces a second combination signal as a signal which does not exceed the reference voltage in the range, and supplies a direct-current combination signal between the electrodes after the supply of the first and second combination signal thereto.

摘要： [Problems] Addition of an organic acid such as a dicarboxylic acid to a soldering flux in order to improve wettability causes a reaction with copper oxide to form a metallic soap of copper having a green color. Although this metallic soap of copper is not corrosive and does not decrease reliability, its external appearance is impossible to distinguish it from verdigris which is indicative of corrosion. There is need for a soldering flux which does not form a metallic soap of copper.[Means for Solving the Problems] Addition of a tetrazole or a tetrazole derivative to a soldering flux can prevent carboxyl groups from reacting exclusively with copper ions, thereby suppressing the formation of a metallic soap of copper having a green color. Among tetrazoles and tetrazole derivatives, 5-phenyl-1H-tetrazole and its derivatives which have hydrogen as a substituent in the 1-position and a phenyl, group which strongly attracts electron in the 5-position are effective at improving soldering since they result in an increased polarity in the solvent.

摘要： A snare strainer adapted to a snare drum comprises first and second strainers, which are attached to opposite positions on the exterior circumferential surface of a drum cylinder and by which a snappy member including snares is controlled to move in close contact with or separate from the backside drumhead upon operation of a switch mechanism. One end of an interconnection member included in the snappy member is held between first and second holding members of the first strainer, and the other end is held between third and fourth holding members of the second strainer. A tension adjustment screw is operated to adjust tension applied to the snappy member, which can be visually observed using the scale. Hence, it is easy for the human operator to attach and replace the snappy member and to replace the backside drumhead with another drumhead in a short period of time.

摘要： A sound pickup device, which is arranged in proximity to a percussion instrument (e.g., a bass drum), comprises a diaphragm stretched under tension over an opening of a shell having a cylindrical shape, and an electroacoustic transducer arranged inside of the shell. The electroacoustic transducer comprises a magnetic transducer or a speaker unit. Herein, the percussion instrument is played to produce the low-pitch sound, which is transmitted to the diaphragm to vibrate so that the electroacoustic transducer is activated to convert the low-pitch sound into an electric signal, based on which the low-pitch sound is reproduced by a sound system with a high fidelity to the original sound.
