Title: Field-effect transistor
Inventor: HAYASHI HISAO
IPC: H01L29/423
Filed: 1986-03-26
Abstract: PURPOSE:To prevent the generation of a reactive region in the lower section of a channel by a depletion layer by forming a gate electrode extending over the whole circumference on the circumferential surface of the channel through a gate insulating film. CONSTITUTION:Since a channel 3 has structure in which it is surrounded by a gate electrode 7 through a gate insulating film 6 extending over the whole circumferential surface, an electric field can be applied to the channel 3 from the whole circumferential surface of the channel 3 through the gate electrode 7. Consequently, an electrical effect on the channel can further be increased by the same gate voltage, thus improving mutual conductance (gm). Effective channel width can be made wider than width viewed from the surface of a substrate 1 of the channel 3 by twice or more, thus increasing effective channel width, enhancing the degree of integration of a field-effect transistor, then improving gm. A large reactive region by a depletion layer is not shaped in the channel.

Filed: 1985-03-30
Abstract: PURPOSE:To execute satisfactorily the control and the management of the quality in various types of the processing process of the paper making process by measuring by measured luminous intensity in a forward or backward position. CONSTITUTION:On a circular circumference at the suitable distance interval from a suspension L luminous intensity sensor 3 is arranged at plural positions from forward position (a) to the backward position (b) of the suspension L and measured luminous intensity in the plural positions of positions (a) and (b) is measured by respective luminous intensity sensors 3. In a constant pulp density density, the difference occurs at the measured luminous intensity by the change of a CSF and as beating proceeds, the measured luminous intensity is increased in the backward position (b) and in the forward position (a) the intensity is reduced reversely. Namely, the intensity is changed corresponding to the change of the measured luminous intensity. Therefore, in the constant pulp density, by measuring and obtaining beforehand the corresponding relation of the beating degree and the measured luminous intensity corresponding to the pulp density, the beating degree can be calculated from the measured luminous intensity which is measured.

Title: Mis type semiconductor device
Inventor: MURAYAMA MOTOAKI
IPC: H01L29/10
Filed: 1984-04-05
Abstract: PURPOSE:To obtain the speed of operation according to a deisgn value by forming the channel width of a MIS type element shaped to a semiconductor substrate so as to have specific relationship with drain resistance, source resistance and channel conductance. CONSTITUTION:When sufficient contact holes 4 are formed to a source 1 and a drain 2 in a MIS type element, effective channel width V is approximately equal to geometrical channel width W. When contact holes 4' are shaped only on a diagonal even in the same geometrical channel width W, however, effective channel width V is made smaller than the geometrical channel width W. Effective channel width V is shown in formula I by representing the MIS type element by a distributed constant network. Effective channel width V is the function of geometrical channel width W at that time, and takes a maximum value on formula II. Consequently, effective channel width V inversely lowers even when geometrical channel width W is brought to a value higher than one in formula II. As a result, the dimensions of the MIS type element are designed so as to satisfy formula III. Accordingly, a design in which source resistance and drain resistance are considered is obtained, and the speed of operation satisfying a design value is acquired.
