Abstract: PURPOSE:To improve transfer efficiency of 1-2 digits, by forming a new electrostatic induction transistor SIT having a junction gate type or an MOS type, which has high gm (transmission conductance in the forward direction) and has ideal saturation characteristics. CONSTITUTION:The distance between a p<+> region 206, which is connected to a transfer gate electrode TG1, and a p<+> region 207, which is connected to a shielding gate electrode SG1, is made to be LTS1. The channel width determined by the p<+> region 207 is made to be WS1. Then relationship LTS1>WS1 is to be obtained. The distance between a p<+> region 208, which is connected to a transfer gate electrode TG2, and a p<+> region 209, which is connected to a shielding gate electrode SG2, is made to be LTS2. The channel width determined by the p<+> region 209 is made to be WS2. Then relationship LTS2>WS2 is to be obtained. Based upon the above data, layout, sizes and impurity distribution are determined. Thus a new SIT, which can implement ideal saturation characteristics, is obtained.

And catalyst particulates are dispersed from the admixture so obtained, using roll mills 6, 7 and 8. While the admixture is transferred from the roll 6 to the roll 8, the dispersion of the catalyst particulates progresses and a paste available is scraped with a scraper 9. Then, pure water or, for example, pure water of 1,400ml to 2,700ml is added to the paste, the dispersion of fluorine resin system amounting to 113ml to 245ml is added, and the catalyst particulates are uniformly and well mixed and dispersed with a supersonic dispersing machine. Then, a mixed dispersion substance is applied to a carbon base material. After the catalyst is removed via a vacuum drying method, the dispersion substance is pressurized at a temperature of 350 deg.C and PTEE particulates are melted, thereby binding the catalyst particulates and making the adhesion thereof to the carbon base material.

Abstract: PURPOSE:To expand the range of phase control by hanging width of expansion of a differentiation pulse expansion circuit by means of a pull-in range setting signal in a phase control circuit using a reference clock signal so as to control the phase of a basic clock. CONSTITUTION:A differentiation pulse expansion circuit 31 is added to a conventional system comprising of a 0-phase/pi-phase clock generating circuit 20, a switching signal generating circuit 27 and a phase comparator circuit 30. The circuit 31 converts the pulse generated by a differentiation circuit 26 into an expansion pulse having a width by means of a pull-in range setting signal and gives the result to a circuit 27. The circuit 27 switches a 2 1 multiplex circuit 23 to allow a 0-phase and a pi-phase clock alternately to be outputted while an expansion pulse is inputted. The 0-phase and pi-phase clock is subject to multiplex for an optional number of times by means of a multiplex circuit 23 by changing the expansion width of the circuit 31 by a pull-in range setting signal. Moreover, plural clocks are inserted and deleted by a gate 24 by using an inhibition signal by the output of the circuits 31, 30 to increase the range in the phase control with respect to a reference clock.

Filed: 1992-04-30
Abstract: PURPOSE:To industrially advantageously obtain the fluorenes having uniform compsns. by introducing a carbonaceous raw material which does not contain particles exceeding specific sizes in accompaniment with gas into hot plasma. CONSTITUTION:The desired fluorenes are obtd. by introducing the carbonaceous raw material in a suspended state of <=100mum in accompaniment with the gas into the hot plasma and evaporating the raw material by heating, then cooling the material. The carbonaceous raw material to be used is not particularly restricted to the material if it is mainly consisting of the carbon and may, in some cases, contain elements, such as hydrogen or oxygen other then carbon and the materials having a high content of the carbon are adequately used. The method for introducing the carbonaceous raw material into the hot plasma is preferably to introduce the raw material by dispersing the material into the gaseous flow of the introduced gas. While the carbonaceous raw material which does not contain the particles exceeding 100mum is preferable, the raw material which contains >=60wt.% particles below <20mum, and further the particles below <10mum, are more preferable.

Abstract: PURPOSE:To impart proper frictional-electrification charges to a developer by means of a regulating member without damaging the developer even when the developer with small particle diameter is used in a high humidity environment, to form the uniform thin layer of the developer on a developer carrier and to obtain a satisfactory picture by means of development. CONSTITUTION:A blade 35 is constituted in such a manner that a composite elastic body layer 32 consisting of a compressed elastic layer 31 and an elastic thin plate 30 is provided on a rigid support 33. At the time of the rotation of a developing sleeve 3, it is made to abut on up to one end 30d on the upstream side of the elastic thin plate 30 by the deformation of the elastic body layer 32 caused by the frictional force. Since the blade 35 is flexible, it widely abuts even at low abutting pressure, so that toner can be frictionally charged for a sufficient time. Also, since it is abutted on until the one end 30d fo the elastic thin plate 30, a big wedge-shaped space which results in the excessive coating of toner 6 is not generated between the sleeve 3 and itself, and the uniform thin layer of the toner 6 can be formed on the sleeve 3.
