Title: Valve device and fuel tank using the same
Inventor: ITO MOTOYA
IPC: F16K1/14
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive valve device capable of opening and closing a valve by utilizing the size of specific gravity of fuel and air, without using a solenoid valve. SOLUTION: By utilizing the size of specific gravity of fuel and air and a head difference of each tank of a two-vessel type fuel tank, a ball-shaped valve element 31 moves at the inside of a branch chamber 25 from a high pressure side to a low pressure side. By this valve element 31, a low pressure side fuel passage 32 or 33 is closed. By opening a high pressure side fuel passage 32 or 33, fuel is sucked from the high pressure side passage 32 or 33 to a discharge passage 34. Therefore, because fuel on a side whose liquid level is high is consumed earlier than fuel on a side whose liquid level is low, fuel is discharged from the discharge passage 34 in a direction that a pressure difference becomes small.  Therefore, because fuel having a liquid surface of the high liquid level is preferentially sucked by a fuel pump, fuel can be consumed in a well-balanced and equal state from a plurality of fuel storing parts.

Title: Rotary recorder
Inventor: KOIKE TAKASHI
IPC: G11B19/28
Filed: 1985-04-19
Abstract: PURPOSE:To attain easily the common use of a single rotary recorder device among plural types of rotary recording media by making use of two identification marks put on the different rotary recording media with a distance secured between them by each revolving angle to control the revolving speed of said recording media through hardware. CONSTITUTION:A revolving speed control means 10 controls the revolving speed of a motor 11 by the output of a comparator 9 so that the revolving speed of a rotary recording medium 1 is reduced when the count value of a counter 8 is larger than the set value of the comparator 9 and vice versa. Thus the coincidence is secured between said both values. Here, the revolving angle thetabetween both identification marks 2 and 3 is varied according to the revolving speed of each medium 1 together with the set value of the comparator 9 kept at a fixed level. Thus the revolving speed of each recording medium is controlled automatically to each corresponding level. Therefore the type of the medium 1 can be discriminated by measuring its revolving speed respectively.

Title: Method for detecting optical transmission line length of optical transmission devices, and optical signal transmission system having optical transmission line length-detecting function
Inventor: YONEDA HIDEHIKO
IPC: H04B10/278
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a versatile method for detecting an optical transmission line length without requiring special measuring equipment. SOLUTION: A portable child unit 2 can be connected to optical fiber cables 51, 52 coupled to a parent unit 1. When a position detection signal is sent to the optical fiber cable 51 from the parent unit 1, the child unit 2 receives the position detection signal and sends to the optical fiber cable 52. The parent unit 1 calculates a delay time after the position detection signal is sent out before the position detection signal is returned. An optical transmission line length from the parent unit 1 to the child unit 2 is operated based on the delay time. A connection position of the child unit 2 can thus be automatically measured without requiring a special device.  The method is widely applicable to optical transmission system having a pair of optical transmission lines for transmitting light signals to opposite directions between the parent and child units, and has sufficient versatility.

Abstract: PURPOSE:To improve adhesion between a roll and a material to be transported by arranging the constitution in such a way that a roll having a conductive layer formed along at least surface layer part and an electrode connected to an outside high voltage power source and connected to the conductive layer are provided. CONSTITUTION:When a high voltage power source 30 is turned on at the same time as the power source of a printer is turned on, high voltage with very small current value is applied on an electrode 40. Since conductive metal coated microspheres are dispersedly mingled into an intermediate tube 12, charge from the electrode 40 becomes an ion and flies in the air and electrify the surface of the intermediate tube 12. As the result of it, an electrostatic place is formed and polarigation is caused in a printing paper sent to a platen roll 10 by the electrostatic place. As the result of it, the printing paper is adsorbed to the platen roll 10 side and adhered to the surface of the roll 10 and accordingly high grade printing becomes possible. Further noise and vibration levels accompanied by the printing action is sharply decreased as compared when used the conventional platen roll.
