IPC: G09G3/36
Filed: 1988-06-27
Abstract: PURPOSE:To reduce flicker by adopting a segmented common electrode and supplying an AC amplitude modulation pulse on a common potential. CONSTITUTION:The common electrode 9 is segmented for each row so as to supply a signal independently for each row and when a FET 3 is turned off, an AC signal in which the envelope of the amplitude peak varies opposite to the voltage drop is applied to other common electrodes 9 clipping the liquid crystal 1 while superimposed on the common potential so that the brightness change in each picture element due to the voltage drop caused during one frame of gate nonselection period caused by the effect of the resistive component of the liquid crystal 1 or the like. Thus, the brightness change is reduced considerably in average over each frame.

Filed: 1980-11-10
Abstract: PURPOSE: Polyester fibers that have a number of depressed grooves on the surface, which have a long axis directed perpendicularly to the fiber axis and saw- teeth like peripheries, thus showing good luster, friction properties, antipilling and antisnagging properties.  
     CONSTITUTION: A polyester mixed with 0.5W10wt% of a powder of 1W500 millimicron diameter is melt-spun simply or subjected to conjugate spinning so that more than 30% surface is covered and wound up. Then, the fiber is treated under tension of 60W95% primary yield stress at a temperature lower than the secondary transition point for an enough time to produce fine crackings, then drawn. The resultant fiber is treated with an alkaline solution to reduce the weight by more than 0.1wt% to make more than 25, per 1mm fiber length, of depressed grooves with a long axis directed perpendicularly to the fiber axis and peripheries of saw-teeth shape, thus producing the objective fiber.

Title: Solenoid valve for liquid fuel injection pump
Inventor: TAKAHASHI IKUO
IPC: F02M41/06
Filed: 1981-10-07
Abstract: PURPOSE:To reduce the influence due to the variation of the fuel pressure, by constructing such that it will conduct to the fuel path of the solenoid valve for weighing the fuel. CONSTITUTION:The lower portion of the weighing orifice will conduct to the longitudinal hole 16 of a conical valve tube 9, which will form the conical valve at the intermediate portion while a lateral hole 16 is provided to conduct with the longitudinal hole 16. The lower portion of the conical valve section is connected through a connecting rod to a movable core 8 where said connecting rod is fitted in the hole of a guide board 7 held by a valve casing 20. The conical valve tube 9 can slide up and down in a guide tube 10. When the conical valve section will contact with a valve seat 11 to choke the fuel path comprised of a lateral hole 15, longitudinal hole 16, weighing orifice 12 and a inlet port 3, the majority of the fuel pressure in a circular chamber 14 will function in the direction to compress the conical valve tube 9 and hardly function on the choked portion of the valve. Consequently the variation of the fuel pressure will never influence on the open/close function of the valve.

Abstract: PURPOSE: To prevent the refrigerant leakage of a rotary compressor for air conditioning system by providing a floating ring between the side plates of both sides of a cylinder and a relative moving surface of a rotor.  
     CONSTITUTION: A side plate 8 is provided with a slot 21 storing a floating ring 10. The floating ring 10 is stored in a sliding manner between a rotor 2. And specified clearances δ1 to δ5 are provided in the surrounding spaces 25 to 29. With this construction, the fluid on the high pressure side Pd is branched into clearances 29 ans 27. At the clearance 29, the pressure is distributed as shown in P2. As there exists a very slight clearance between 27, 28 and 26, no leakage is produced on the lower pressure side Po. P1 is equivalent to Pd while P1 is greater than P2. The floating ring 10 is moved to the side of rotor 2, thereby reducing the clearance 29. Therefore, fluid leakage from the high pressure side Pd can be prevented.
