IPC: H01L27/092
Filed: 1988-12-19
Abstract: PURPOSE: To reduce a surface area and a power consumption by arraying a 1st circuit which has a 1st and a 2nd series-connected FET and a 2nd circuit which has a 3rd FET in parallel to each other, and connecting them between an input and an output terminal.

When the voltages of the control electrodes of N.FETs 18 and 20 rise while the voltage of NdA falls, an FET 18 turns on and then the voltage of NdB falls, so that the voltages at the terminals OUT and NdC fall. The voltage at the terminal OUT falls to Vdd/2 at time t2 and the delay from the terminal IN to the terminal OUT becomes equal to t2 -t1 . Then the voltage at the terminal OUT falls to 0V at time t3 . The voltage IN begins to fall at time t4 , reaches Vdd/2 at time t4 , and then begins to rise thereafter.  At time t6 , the voltage at the terminal OUT reaches Vdd/2 and at time t7 , a source voltage Vdd corresponding to the full power is obtained.

Title: Pneumatic tire
Inventor: WATANABE SHINICHI
IPC: B60C9/08
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To restrain the deterioration of wet performance caused by wearing and also an increase in noise. SOLUTION: A siping 22 formed for a block 18 comprises a narrow groove section 26 of width x1 on the side of a tread 24 and a broad groove section 30 on the side of a bottom section 28 formed in the direction of (d). The connection section of the narrow groove section 26 and the broad groove section 30 is formed inclined along the direction of (a). Therefore, when a pneumatic tire having such block 18 on a tread surface wears, the following phenomenon will occur. That is, in the initial period of wearing as the drainage performance of a main groove, etc., is excellent, noise is restrained only by the narrow groove section 26, and in the middle period of wearing as the drainage performance of the main groove is deteriorated, the broad groove section 30 is gradually exposed for improving the drainage performance of the siping for compensating this deterioration.  In the last period of wearing, although only the broad groove section 30 displays a drainage performance, since the depth of the siping is small, an increase in noise is restrained. This constitution thus restrain the deterioration of the wet performance of a tire while restraining an increase in noise to the last period of wearing.

Title: Dc cable
Inventor: IINUMA KOICHI
IPC: C08L23/26
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent the DC breakdown strength of a DC cable having an insulator comprising a maleic anhydride-modified polyethylene from deteriorating. SOLUTION: This DC cable is obtained by regulating the molar ratio (A/B) of the moisture content (A) in an insulator to the content (B) of maleic anhydride groups to <=1.0, preferably <=0.6, keeping an adequate amount of hydrophilic groups in a state dispersed in the insulator, thereby reducing the amount of space charge storage and improving the DC breakdown voltage at the time of applying a DC voltage. The reason for the DC cable is that the DC breakdown strength of a conventional DC cable is deteriorated as a result of the ring opening of all the maleic anhydride groups subjected to graft polymerization and the subsequent formation of a carboxylic acid when the insulator absorbs a large amount of moisture from the atmosphere, etc., in the conventional DC cable.
