Title: Sense amplifier
Inventor: INOUE YOSHINAGA
IPC: G11C11/409
Filed: 1990-11-28
Abstract: PURPOSE:To compensate the difference of delay times in operation between a sense amplifier in the signal wiring closest to the generating source of sense amplifier driving signal and an amplifier most apart from the source by increasing stepwise the gains of transistors in the sense amplifiers. CONSTITUTION:A word line ML becomes 'H' in an X address, next an activating signal Sn for sense amplifier SA becomes 'H', and a TR5 is turned ON for making a driving signal Sg to 'L'. Succeedingly, an activating signal Sp for sense amplifier SA becomes 'L' and a TR4 is turned ON for making a driving signal Sv to 'H'. Then, bit lines BL, -BL2 are amplified. In the waveforms of BLn, -BLn most apart from the generating source of SA driving signals Sv, Sg, the start of amplification is delayed by the time (t) as compared with the waveforms of BLphi, -BLphi closest to the generating source of Sv, Sg. The gains of transistors in the SA are made different for SA1a and SA1b, and the times required for the BL to finish the amplification to 'H' and 'L' are expressed as t1 for BLphi, -BLphi and t2 for BLn, -BLn, and when the relation t1>t2 is selected, the delay of access can be suppressed to less than t2-t1.

Title: Bag
Inventor: KUROKAWA MASAYUKI
IPC: A45C7/00
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To carry or keep a bag being a small size at the time of non-usage jointing the two outer peripheral edge fasteners of a flat and soft material to obtain a bag shape and to contain an object. SOLUTION: A deformation possible material is used as the flat and soft material 2 and its shape is made to be an oval, for example. The shape and the size of the two flat and soft materials 2 are set so as to permit length in the respective outer peripheral edge fastener 1 parts to be the same. When the length ratio of a long axis with a short axis in the oval of the two flat and soft materials 2 are made large, the more stereoscopic and three-dimensional bag shape is obtained at the time of jointing them. The bag is made to be the bag shape by jointing the two outer peripheral edges fasteners 1 of the flat and soft material 2 at the time of containing the object.  In the meantime, when a portable function as a bag is not required, the outer peripheral edge fasteners 1 are opened so as to be the two flat and soft materials 2 so that a form is changed from the bag-shaped large one to the flat and thin one. Therefore, the bag is carried or kept at the time of non-usage by being small.

At this time, an air suction fan is at a halt, but air is sucked through the air suction fan. The cooling plate 1 is cooled by the air flow and the surrounding atmosphere of the fluorescent lamp 5 is indirectly cooled by the cooling plate 1.  When the atmospheric temperature is further increases, the air suction fan as well as the exhaust fan are actuated and air is pressed into the air duct 12 by the air suction fan, thus increasing the amount of air flowing through the air duct 12 and increasing the amount of heat radiated from the cooling plate 1 and decreasing the atmospheric temperature.
