Title: Field effect transistor
Inventor: YAMASHITA YUKIHIRO
IPC: H01L27/092
Filed: 1990-10-29
Abstract: PURPOSE:To suppress leak current of a field effect transistor, thereby reducing the power consumption when the transistor is off, by providing the field effect transistor with the function of excluding a crrier from the channel forming area when the field effect transistor is off. CONSTITUTION:Polycrystalline silicon film 9 is connected to a power supply. Since film 9 is electrically connected also to polycrystalline silicon film 11, the same voltage as that of the power supply is applied through film 11 to channel forming area 12. Accordingly, when a p-type MOS transistor 21 is off, to the area 12 a positive voltage is applied, holes in area 12 all flow into drain area 13, and, as a result, the drain area 13 becomes empty of holes, thereby being able to suppress leak current between the source area 14 and the drain area 13.

Title: Magnetic field measuring apparatus
Inventor: KAMATA OSAMU
IPC: G01R33/032
Filed: 1985-12-24
Abstract: PURPOSE:To obtain a highly sensitive and excellent reproducibility, by arranging a magnetooptic element comprising rare earth garnet crystal having a stripe magnetic domain between a polarizer and an analyzer to pass light in a specified direction. CONSTITUTION:A magnetooptic element 1 employs a rare earth garnet crystal having a stripe magnetic domain. Light is made to pass horizontally to the surface where the stripe magnetic domain is observed. When a magnetic field H is applied to a magnetooptic converter section thus arranged, in the case of a weak magnetic field, only inplane magnetization turns but there is no change in the direction of the strip magnetic domain. Faraday effect due to the turning of the magnetization is proportional to the intensity H of a magnetic field. The turning of the magnetization is so uniform with respect to the beam diameter of incident light. There is not any movement of the magnetic wall, which can not be ignored for the beam dia. of the incident light, hence regarded as a main cause of the worsened reproducibility. The use of the magnetooptic converter section makes available a magnetic field sensor with a higher reproducibility.
