Title: Liquid crystal display device, driving method and driving circuit
Inventor: SAIWAI SHIYOUICHI
IPC: G02F1/133
Filed: 1999-12-14
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device, driving method, and driving circuit capable of preventing, a flicker from occurring, and also avoiding the changing over of an unnecessary polarity pattern. SOLUTION: A gray level difference judging part 41 detects a gray level difference between the image data to be supplied to two pixels of the same color, and when the gray level difference exceeds a prescribed value, a big-and- small relation same pattern detecting part 43 and a lateral direction pattern number count part 44 check whether or not a big-and-small relation between the gray levels of the two pixels each and the same big-and-small relation continue by a certain number or more in the lateral direction. And, when the relations continue by the certain number or more, the big-and-small relation is checked in the vertical direction in plural continuous lines, and the presence or absence of flicker is judged from the result.  And, when there is a fear of occurrence of flickers over plural frames, a polarity pattern for deciding the polarity of the image data to be supplied to a liquid crystal display panel from a data driver is changed over by varying a polarity pattern change-over signal FLK.

IPC: B60T13/573
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a larger braking force with a lighter depressing force by bringing a brake booster into full load condition when a depressing force exceeds a specified limit. SOLUTION: First and second retainers 41 and 42 installed displaceably in a valve body 6 and a reaction transmitting means 33 provided with springs 43 and 44 which are charged between both retainers at a specified set load and normally hold these retainers at a distance is provided between a valve plunger 17 and a reaction disk 35. The brake reaction from the reaction disk is transmitted to the valve plunger normally through a plate plunger 34, the first retainer, springs, and the second retainer. However, when the spring is compressed and first retainer is brought into contact with a valve body, the brake reaction is transmitted from the first retainer to the valve body. Thus, when the first retainer is brought in contact with the valve body, a brake booster is brought into a full load condition and, therefore, a powerful braking force can be obtained with a light depressing force.

Title: Method for removing halogen radical in copper halide solution
Inventor: INOKO MASANORI
IPC: C23F1/46
Filed: 1991-12-27
Abstract: PURPOSE:To remove a halogen radical from copper halide solution containing free halogen and a complex of halogen and copper. CONSTITUTION:An anion-exchange membrane 2 is arranged inside a dialysis tank 1 so that the dialysis tank 1 may be divided into a copper halide solution tank 11 and a solvent tank 12 by it. Copper halide solution containing free halogen and a complex of halogen and copper is fed to the copper halide solution tank 11 and simultaneously to the solvent tank 12 is fed, for example, ion exchanged water. Since the free halogen existing in the copper halide solution is passed through the anion-exchange membrane 2 to transfer it to the ion exchanged water side, causing the free halogen on the copper solution side to be decreased, the halogen in the complex is eliminated as the free halogen in order to maintain the equilibrium and the eliminated halogen is similarly transferred to the ion exchanged water side afterwards. Therefore, the halogen radical existing as a free halogen or the complex is removed.
