Title: Driving method of liquid crystal display element
Inventor: SHIOJI MITSUAKI
IPC: G02F1/133
Filed: 1984-10-24
Abstract: PURPOSE:To maximize the contrast between a display part and a non-display part of a liquid crystal display element by controlling impressed voltage maxi mizing or minimizing a transmission factor in each wavelength of light. CONSTITUTION:A segment signal generates a phase reversed to that of non- transmission and synthesized signals become 2Vs-VR.2VS-VG.2VS-VB for respective colors R, G and B. The smallest signal 2VS0-VB must be set up to a high voltage satisfying the transmission factor sufficiently. When light is not transmitted, the transmission factors of respective colors R, G, B are turned to the minimum values which are almost equal to the values determined by the characteristics of a polarizing plate. When light is transmitted, the transmission factors of respective colors R, G, B are almost equal to the values determined by the characteristics of the polarizing plate similarly. Namely, the light dependence of contract disappears and the contrast is increased.

Title: Shaft bracket
Inventor: KUMAI YASUHIKO
IPC: B63H23/36
Filed: 1984-10-27
Abstract: PURPOSE:To reduce the cavitation generated in a bracket part, wave making resistance, noise, etc. by constituting a shaft bracket axially supporting the propulsion shaft of a ship by the hull outer plates, from an arm part and a movable blade which freely turns, having said arm part as axis center, and allowing said movable bade to follow the streamline. CONSTITUTION:During the navigation of a ship, if the streamline direction in the vicinity of a shaft bracket 1 changes, the difference of fluid pressure is generated between the both blade surfaces of a movable blade 3. The movable blade turns according to the differential pressure until the wing chord 10 coincides with the streamline direction, having an arm part 2 as axis center, and then the standstill balanced state is generated. Since the movable blade 3 can always follow the change of the steamline of the shaft bracket part, the generated cavitation, wave making resistance, noise, etc. can be reduced. Therefore, the reduction of the propulsion faculty of a propeller can be prevented.

Patent JP-S6468012-A (JP)
Title: Latch circuit
Inventor: IWATA HIROMITSU
IPC: H03K3/286
Filed: 1987-09-08
Abstract: PURPOSE:To improve the dropping voltage characteristic by operating an output transistor TR with the base potential self-bias in the reset state, namely, the thyristor operation state. CONSTITUTION:When a voltage in the high level is applied to an input terminal 1, an NPN TR Q2 is operated to drive PNP TRs Q3 and Q4. The circuit consisting of TRs Q2 and Q3 and resistances R2-R4 is a latch circuit: though a set terminal goes to the low level after operation of TRs Q2-Q4, TRs Q4 and Q5 are kept operated because the TR Q2 is driven by the TR Q3, and a TR Q6 is cut off and an output terminal 3 goes to the high level. When a voltage in the high level is applied to an input terminal 2 and a TR Q1 is made conductive and the TR Q2 is cut off, the TR Q6 is made conductive because TRs Q3-Q5 are cut off, and the output terminal goes to the low level. Thus, the dropping voltage characteristic is improved.
