Title: Naphthalene compound, liquid crystal composition and liquid crystal element
Inventor: KAYASHIMA HIROE
IPC: C07D213/80
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain a new compound useful as a component for liquid crystal compositions. SOLUTION: A compound of formula I [R1 is a 1-20C alkyl, a 2-20C alkoxyalkyl, etc.; R2 is a 2-20C alkyl, a 3-20C alkoxyalkyl, etc.; Y1 is O, COO, etc.; Y2 is COO, CH2 O, etc.; A is a group of formula II, etc.; (n) is 0,1]. For example, 6-cyano-2-tetrahydropyranyloxynapththalene. The compound of formula I is obtained e.g. by esterifying a compound of formula III with a compound of formula IV in the presence of a catalyst such as 4-pyrrolidinopyridine and a condensing agent such as N,N'-dicyclohexylcarbodiimide. A liquid crystal composition containing one or more kinds of the compounds in an amount of 1-99wt.% is more excellent in compatibility between liquid crystal compounds, tilt angle, and orientation characteristics on an orientation film than those of conventional compositions.  The liquid crystal composition is disposed between a pair of electrode plates to form a liquid crystal element.

Title: Pressure control valve
Inventor: NAKAJIMA YOICHI
IPC: F02M37/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of a flowing noise within a pressure control valve itself, thereby reducing the jetting energy of the return fuel, which is discharged from the pressure control valve into a fuel tank. SOLUTION: In a fuel return passage 6, a valve seat 7 is arranged at an up-stream end 6A of the passage 6, while a down-stream end 6B directly opens to a fuel tank via a down-stream opening 6C. An orifice 12 is arranged, facing to the valve seat 7, while a jetting stream suppressing means J is prepared between a down-stream end 12C of the orifice 12 and the down-stream opening 6C in the fuel return passage 6. The flowing noise of the fuel, which flows down through the valve seat 7, is reduced by the orifice 12. The energy of the jetting stream, which flows from the down-stream end 12C of the orifice 12, is weakened by the jetting stream suppressing means J, so that the weakened jetting stream is discharged from the down-stream end 6C in the fuel return passage 6 into the fuel tank. Thus, the noise in the fuel tank can effectively be reduced.

Title: Method for replenishing developing powder of electrostatic printer
Inventor: IINO YOSHIO
IPC: G03G21/00
Filed: 1980-06-30
Abstract: PURPOSE:To performing printing of constant density regardless of the varying amounts of printing by adding the amount of developing powder consumption corresponding to the amount of printing and the amount of the developing powder consumed in correspondence to the number of revolutions of a developing roller thereby controlling the replenishing amount. CONSTITUTION:A printing signal indicating the amount of printing is inputted from the upper device 9 of a central processing unit or the like to a counter 10. On the other hand, the count value corresponding to the number of revolutions of the developing roller is inputted to a counter 14 via an encoder 15 connected to a develoing roller driving source 16. In an adder 11, the count values of both counters 10, 14 are added and the output thereof is inputted to a developing powder hopper driving part 12 which in turn controls a developing powder feed roller, thereby replenishing the required amount of the developing powder. Since the developing powder consumed in correspondence to the number of revolutions of the developing roller other than the amount of printing is replenished by this, the density of printing does not lower even in case when the amount of printing is small, thus good printing of always constant quality is accomplished.
