Title: Color liquid crystal display element
Inventor: KANEMOTO AKIHIKO
IPC: G02F1/1335
Filed: 1991-11-18
Abstract: PURPOSE:To obtain the liquid crystal display element which enables the reduction of electric power consumption and weight by providing light imparting means which can intensify the brightness of picture elements to each of the respective picture elements. CONSTITUTION:If a voltage is not impressed between electrodes 11 and 12, liquid crystal molecules 14 are not arrayed in a specified direction and, therefore, dyestuff molecules 15 face random directions as well and red and green dyestuffs 15R, 15G emit red and green fluorescence by absorbing incident light. Green dystuff 15B faces random directions as well but the light from a light transmission means 13 is absorbed by the dichromatic dyestuff 15B in such a case and, therefore, the display is darkened. If an electric field is impressed to the green picture element 15G, the liquid crystal molecules 14 are arranged in the electric field direction and, therefore, the state of hardly absorbing the incident light is attained and the display is blackened. The same holds true even when the electric field is impressed to the red picture element. The state of hardly absorbing the light from the light transmission means 13 is attained when the electric field is impressed to the blue picture element and, therefore, the display is conversely brightened.

Title: Exhaust structure
Inventor: MURAMATSU TORU
IPC: B09B3/00
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To prevent offensive odor or harmful insects from flowing back from a sewer pipe. SOLUTION: A middle part 55 of a sump pump connected with a sewer pipe 9 and having an almost S-shaped watercourse is provided with an inner pipe 56 having a throttle part 57 formed on the upper end face. A lower bending part 51 of a drain trap 50 is provided with a cover member 60 so that an exhaust inner pipe 63 connected with a ventilation hose 25 is inserted into the inner pipe 56. When a ventilation pump stops operating, the pressure inside the inner pipe 56 equals to that inside the drain trap 50, so drain water level inside the inner pipe 56 rises up to almost the same level as that of an upper end 63a of the exhaust inner pipe 63. As a result, drain flows in the inside of the exhaust inner pipe 63 to make the exhaust inner pipe 63 be a sealed state, preventing the backflow of offensive odor and the like from the sewer pipe 9 when the ventilation pump operates.

Title: Input circuit and input circuit characteristic setting method
Inventor: NUGA KENJI
IPC: H03K19/003
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction due to high frequency noise by amplifying a difference between a small amplitude signal and a reference voltage signal and waveform-shaping a received amplified output signal. SOLUTION: When a level of a node A gradually transits toward a high level, an NMOS transistor(TR) being a component of an inverter 21 is conductive and a PMOS TR 22 is conductive, then a current starts flowing to ground through a path consisting of a power supply VDD, the PMOS TR 22 and the NMOS TR being a component of the inverter 21. When the level of the node A goes deeply to the high level, the resistance of the inverter 21 is decreased, resulting that a level at a connecting point between the inverter 21 and the PMOS TR 22 is decreased. When the level of the node A increases further and an inverter 23 irtverts its input signal, a node B transits to a high level. Since the high level signal is given to a gate of the PMOS TR 22, the PMOS TR 22 is nonconductive resulting in cutting off the current having flowed to ground.
