Title: Polarization controller and liquid crystal display device
Inventor: KOTAKE RYOTA
IPC: G02F1/13
Filed: 1990-06-19
Abstract: PURPOSE:To output all incident light as linear polarized light in one direction by providing a mirror which polarizes a polarized light component, polarized without being transmitted through a polarization beam splitter, in the same direction with a polarized component transmitted through the polarization beam splitter and a TN liquid crystal cell where the polarized light component reflected by the mirror is made incident. CONSTITUTION:The polarization controller 10 has the polarization beam splitter 11, the mirror 12, and TN liquid crystal cell 13. The light which is outputted by a light source is light which has both components of a P wave and an S wave, but when the light is mad incident on the polarization beam splitter 11, only the P wave is transmitted and the S wave is reflected by 90 deg.. The reflected S wave is optically rotated by 90 deg. through the mirror 12, made incident on the TN liquid crystal cell 13, and rotated by 90 deg., so that the wave is outputted as a P wave. Consequently, the light from the light source is converted into linear polarized light, which is outputted.

IPC: H01L23/60
Filed: 1989-06-20
Abstract: PURPOSE:To expand a width of a depletion layer of a P-N junction and to prevent a junction breakdown by a method wherein, in a C-MOSFET, a high- concentration impurity layer is structured so as to be wrapped by a low- concentration impurity layer. CONSTITUTION:An N<-> well 6a for an FET 1P is formed in a P<-> substrate 5a. A P<+> layer 7a and a P<-> layer 8a which wraps a P<+> layer 9a are formed in the well 6a. A source electrode S1P is attached to the layer 7a, and is connected to a VDD. An insulating film 10a is formed on the layers 7a, 9a; a gate GIP is attached to the film 10a. A drain D1P is formed on the P<+> layer 9a. On the side of an FET 1N, an N<+> drain 13 is wrapped by an N<->. layer 12a in the same manner; an SIN is attached to an N<+> layer 11a and is grounded. Drains of both FET's are connected in common. Since high-concentration layers are wrapped respectively by low-concentration layers at the drains, the low- concentration layers expand a width of a depletion layer of a P-N junction at an operation. Thereby, it is possible to prevent a breakdown of the P-N pin junction by an excess current and an excess voltage within a range where an absolute value of a noise is small; a breakdown-strength performance can be enhanced.

Abstract: PURPOSE:To effectively propel a boat body by providing the boat body with a propelling blade, whose after part is freely rotated by the water-resistance, centering around a supporting shaft, in a predetermined sector-shape range when the boat is moved up and down. CONSTITUTION:When a person on a boat 1 rocks his body right and elft, owing to thus produced rolling of the boat body 1, the after portion of the blade 4, which is installed on the boat-side which going down from the water surface, inclines upward, centering around the shaft 2, and is stopped by the upper limit stopper 5, thereby producing the force that makes the blade moving downward and forward. As a result, the boat-propelling force is produced, thus making the boat advance. At the same time, the propelling blade 4 on the opposite side moves upward, but the after end of the blade 4 moves downward, centering around the shaft 2. It is stopped, however, by the lower limit stoppe 5. Thus, the propelling blade 4 lets the water flow rearward as if the former scoops up the latter. As a reslt, the forward propulsive force is produced, thereby advancing the boat body 1.
