Title: Insulating gate type electrostatic induction transistor
Inventor: YAMADA TAKAHIRO
IPC: H01L29/80
Filed: 1985-07-05
Abstract: PURPOSE:To contrive the remarkable improvement in high-speed characteristic while keeping high gm and low-noise characteristic of a junction gate type SIT by employing the structure in which punch-through is not produced theoretically and applying the reach-through realizing conditions to the width and depth of a channel. CONSTITUTION:For forming a buried channel 102 between an N<+> source region 103 and a drain region 104 to compose a depletion type structure and for preventing the existence of the depletion layers 120 and 121 which expand toward the source region according to a drain voltage, N<+> regions of source and drain are formed in the N epitaxy (or N well) on the P substrate 102. Also an insulating gate electrode 105 is arranged only in the vicinity of the source region in order to efficiently control the potential of an intrinsic gate region 109 by the insulating electrode, thereby preventing it from reaching the drain region. And such a channel depth that a neutral region is not produced in the channel according to the change of potential of the insulating gate electrode 105 is selected. Consequently, punch-through does not occur theoretically and an electric current flows in the depletion layer in a bulk.

Title: Weighing apparatus
Inventor: AOYAMA KENGO
IPC: G01D7/00
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of weighing work on a single screen by changing the bar graph display mode depending on the weighing value close to a target value or not close to the target value. SOLUTION: A display section 13 displays weighting result with a bar graph and a control unit 21 sets a weighing target value. The control unit 21 changes the bar graph display mode depending on the weighing value close to the target value or not close to the target value. Required information can thereby be obtained individually when the current weighing value is far from the target value and when fine adjustment is carried out in order to converge the weighing value to the target value if the weighing target value is set as a target value. Consequently, the work efficiency is enhanced and since only one display 13 is required, the apparatus is advantageous also in the aspect of cost.
