Filed: 1988-12-29
Abstract: PURPOSE:To decrease the interfering noise between bit lines by alternately providing a bit line pair connected to a sense amplifier belonging to a first sense amplifier group and the bit line pair connected to the sense amplifier belonging to a second sense amplifier group. CONSTITUTION:Sense amplifier driving signal lines 25 and 26 are connected to sense amplifiers 27 and 28 respectively connected to two bit lines 31. Out of the sense amplifiers 27 and 28, the sense amplifier 27 belongs to the second sense amplifier group, the sense amplifier 28 belongs to the first sense amplifier, and the sense amplifiers 27, 28 are alternately provided. For this reason, the bit line 31 connected to the sense amplifier 27 and the bit line 31 connected to the sense amplifier 28 are alternately provided. Consequently only one of the bit line pair are continuously sensed out of the bit line pairs, and meanwhile the other bit line pair are not sensed. Thus the interfering noise between the bit lines and the noise generated by a current at the time of driving the sense amplifier can be effectively decreased.

Title: Surge absorber
Inventor: SUMIYOSHI MIKIO
IPC: H01T1/14
Filed: 1987-12-29
Abstract: PURPOSE:To enable a surge absorber to be protected from continuous AC overvoltage by breaking an AC current which flows continuously into the surge absorber using an electrode plate that has a spring property and a low melting point alloy. CONSTITUTION:In case that discharge was continued, electrodes 8a and 8b begin to generate heat by arch heat and joule energy. Hereupon, the electrode 8a contacts by pressure with an electrode plate 12, so the heat of the electrode 8 is immediately transmitted to the electrode plate 12 and then, is transmitted to a soldering part 14. If the soldering part 14 is heated like this, the soldering part 14 begins to fuse rapidly and space between the electrode plates 12 and 13 is opened by a spring property, and the electrode plates 13 shifts to the position shown by broken lines. Hereby, the current which passes through the soldering part 14 is cut off and the current which flows into a discharge gap also becomes zero and the heat generation at the electrodes 8a and 8b are also reduced greatly, and through breakage, etc., of the discharge gap can be avoided.

Abstract: PURPOSE:To obtain images with favorable fixation and drying by such a switching as to lower a driving frequency for a recording head and a feeding velocity for a paper at the time of recording images on an OHP paper, as compared with those values at the time of normal recording. CONSTITUTION:A mode is selected by an OHP mode selecting key on a console. With a recording starting signal inputted, all of a feeding velocity for feeding a paper from a paper-supplying part 303 to registration rollers 415, 416, a feeding velocity for a belt in a belt-feeding part 304 and a discharging velocity for a paper at paper- discharging rollers 211, 212 are set in accordance with low-velocity mode feeding. Power supplies for a heating element A200, a heating element B201 and a fan 203 are switched ON, and auxiliary fixation is conducted. The degree of lowering in velocity for this mode varies depending on the materials of a coating agent on an OHP paper and of an ink, ejection quantity of the ink, and the like. Where ordinary papers and coated papers are fed at a velocity of 100m/sec and a driving frequency therefor is 1.6kHz, and when an appropriate feeding velocity for the OHP paper is 25mm/sec (i.e., 1/4 times 100mm/sec), a driving frequency therefor is 0.4kHz. Thereby, favorable fixation without overflow, bleeding or the like of the ink can be achieved in recording on the OHP paper.
