Filed: 1986-12-03
Abstract: PURPOSE:To obtain a resist having superior resolution and sensitivity for ultraviolet rays together with high resistance to O2 plasma by incorporating a specified polysilane in the resist. CONSTITUTION:Polysilane expressed by the formula is incorporated in a resist. In the formula, R1-R3 are methyl or phenyl group; R4-R8 are H atom or methyl group, but at least one of them is methyl group; n is a positive integer; m is zero or a positive integer. The used polysilane is pref. one having >=1X10<3> mol.wt. from the viewpoint of sensitivity and glass transition point of the polymer. If the mol.wt. is >=5X10<5>, disadvantage in the formation of fine pattern is resulted because of the higher tendency for causing swelling when it is developed. It is preferred from the viewpoint of resolution that the mol.wt. distribution is as near as possible to monodisperse distribution. Since better heat resistance and resolution of the resist are obtd. when the glass transition point of the polymer is as high as possible, it is preferred that the polymer has at least 50 deg.C glass transition point.

Title: Analog memory circuit and analog signal recording method
Inventor: KUSUMOTO KEIICHI
IPC: H01L27/10
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To hold a recorded analog signal for a long time while keeping an initial voltage level without being affected by the generation of a leakage charge from a capacitor in an analog memory circuit recording the analog signal as the charge stored in the capacitor. SOLUTION: The capacitor C2 storing the leakage charge is connected in series to the capacitor C1 holding the analog signal as the charge, and the capacitor C2 holding the leakage charge is initialized when the analog signal is written. The leakage charge occurring in a record hold period is stored in the capacitor. Further, a leakage charge amount is detected, and the charge equivalent to its detected amount is supplied to the capacitor C1 holding the analog signal by a prescribed drive circuit. Thus, even when the recorded analog signal is attenuated by the leakage charge, an initial recording signal level is regenerated by regenerating the leakage charge.

Abstract: PURPOSE:To attain the high speed of an operation by making the master circuit of a D flip-flop have a selecting function selecting either one of parallel input data and reducing a delay in a shift register. CONSTITUTION:In a case that the logical value of a selecting signal S is '1', the output logical value of a two input NOR 55 goes to '0' to make an FET 53 to be an OFF state and one pair of switching transistors 51, 52 inputting data B and/B do not operate. besides, the inverse clock signal/CK is outputted from the output terminal of a two input NOR 54. Further, in a case that the logical value of the signal S is '0'. the output logical value of the two input NOR 54 goes to '0' to mask an FET 18 to be in an OFF state and one pair of transistors 16, 17 do not operate. On the other hand, at this time, the signal/CK is outputted from the output terminal of the two input NOR 55. In above operations, in both cases where logical value of the signal is '1' and '0', the signal passes only two pieces of gates in a master circuit 210 and a slave circuit 200b until data are inputted to the shift register and are outputted from the register.

Title: Water purifier

IPC: C02F1/28
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To drain the water accumulated in a water purifier by setting a drain valve disc in the hose connected to the water discharge part taking out the water purified by the purifying filter material in an outer cylinder. SOLUTION: When tap water is allowed to flow in a water purifier, the interior of the water purifier is held to a pressurized state by water pressure and both of an air intake valve 20 and a residual water drain valve 30 are cut off so as to be isolated from the communication with the outside. Therefore, tap water is treated according to the regular route in the water purifier to be supplied. When the supply of tap water to the water purifier is cut off, water pressure is not applied to the interior of the water purifier and, therefore, both of the air intake valve 20 and the residual water drain valve 30 are opened to communicate with the outside. Herein, the whole of the water in the water purifier flows out of the residual water drain valve 30 and, since no water remains in the water purifier, the propagation of bacteria or the like in the water purifier is not generated.
