Filed: 1988-05-27
Abstract: PURPOSE:To obtain an image having excellent image quality even at and under a high temp. and high humidity by using a toner which is obtd. by polymerizing a polymerizable monomer together with a coloring agent in an aq. soln. by using a surfactant as a dispersant and contains <=1.0wt.% surfactant. CONSTITUTION:The toner which is obtd. by polymerizing the polymerizable monomer together with the coloring agent in the aq. soln. by using the surfactant as the dispersant and contains <=1.0wt.% surfactant is used as the toner to be used for a developer. The toner to be used is obtd. by cleaning, dehydrating and drying the toner after the polymn. in the aq. soln. Such toner contg. <=1.0wt.% surfactant does not exhibit hygroscopicity even at and under the high temp. and high humidity and, therefore, obviates the fogging on a photosensitive drum and the fogging on the image. The sharp[ image having the high image density is thus obtd.

Title: Semiconductor device
Inventor: IWAHASHI HIROSHI
IPC: G06F3/00
Filed: 1982-07-27
Abstract: PURPOSE:To reduce a momentary peak current and attain a high response speed, by delaying and operating plural output buffers at an output time and stopping plural buffers simultaneously as an operation stop time. CONSTITUTION:When a control signal S is (0), data are outputted from output buffers 281-28n. In this case, delay means are provided for the purpose of preventing buffers 281-28n from being turned on simultaneously. This delay means is MOSFET36 connected to a control line 38 on the input side of the signal S. In this MOSFET36, the delay time of the transmission of the signal S for the change of the signal S from (1) to (0) is longer than that for the change from (0) to (1). Consequently, since data are not outputted simultaneously from buffers 281-28n to an external bus, the peak current is not abnormally high. The reason why the transmission time for the change of the signal S from level (0) to level (1) and that from level (1) to level (0) are made different from each other is because the output time is made different when outputs are outputted from output buffers to an external bus 30 and the response speed is made higher when outputs are not outputted.
