Title: Electrostatic attraction multi-nozzle ink jet head
Inventor: KONISHI DAISHI
IPC: B41J2/06
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To realize high speed printing by applying an exciting pulse voltage periodically to a multi-nozzle head under no-voltage state and applying a print voltage to each gate on a gate electrode substrate thereby increasing the flying speed of ink. SOLUTION: When a multi-nozzle head 1 is applied only with an exciting pulse voltage SV of constant period, a no-voltage state takes place in the multi- nozzle head 1 when the exciting pulse voltage SV is not applied. Consequently, a meniscus M having a large amplitude repeating large and small meniscuses is formed at the forward end of each nozzle 1a between the times being applied and not applied with the exciting pulse voltage SV. Consequently, an ink I can be jetted smoothly at high speed from each nozzle 1a by applying a print voltage PV in synchronism with the time when the meniscus M is increased, i.e., when the exciting pulse voltage SV is applied.

Abstract: PURPOSE:To be adaptable for quickly decomposing water-soluble low molecular weight material mixture by using II type selulose crystal phases and selulose non-crystal phases to provide property that distribution coefficient is abruptly changed in a range of specified relatively low molecular weight. CONSTITUTION:II type selulose has the existance of cross linkages between selulose molecular chains in selulose non-crystal phases, apart from selulose particles formed of I type selulose. It contains spherical particles with an average size of 50mum or smaller. When water-soluble high molecular weight material mixture is decomposed, distribution coefficient is abruptly changed in a range of specified molecular weight, for example, such that the distribution coefficient of maltohexaose is 0.25 or less, a difference in distribution coefficient between maltose and maltohexaose or glucose is 0.25 or more and 0.10 or less, respectively, and a separation rate between maltotriose and maltotetraose is 0.4 or more. Such property and a small average particle size are adequate for quickly decomposing and taking up water-soluble low molecular weight material mixture.

Title: Operational amplifier connection circuit

Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide an operational amplifier circuit capable of effectively removing power supply noise without being affected by a minute potential difference and a noise current between ground points to be the cause of noise. SOLUTION: In plural operational amplifiers 13 and 17 serially connected from an upstream side to a downstream side, a reference voltage terminal TREF to be inputted to the operational amplifier 17 on the downstream side is grounded and the reference voltage terminal TREF to be inputted to the operational amplifier 13 on the upstream side is connected through a reference power supply bypass capacitor C1 to the grounded reference voltage terminal of the operational amplifier on the downstream side. Thus, since the minute potential difference is not generated and the noise current is not made to flow between the two reference voltage terminals, the generation of the noise and distortion, etc., of signals outputted from the operational amplifier on the downstream side is surely prevented.  Also, since the reference voltage terminal on the upstream side is connected through the reference power supply bypass capacitor to the reference voltage terminal on the downstream side, the power supply noise is surely removed as well.
