Abstract: A pressure regulating valve includes a piston in a pressure regulating chamber, a valve element axially movable together with the piston, a valve chamber in which an end portion of the valve element is placed, a resinous valve seat which the valve element is brought into contact with or separated from, a coil spring urging the piston in a direction to move the valve element away from the valve seat, and a body member accommodating the valve element and the valve seat. The valve element has an axially extending hollow cylindrical shape. When moved away from the valve seat, the valve element allows communication between the valve chamber and the pressure regulating chamber. The valve seat is arranged to be axially movable. An adjusting screw is provided to move the valve seat for adjusting a contact position with the valve element from outside.

Abstract: A pressure-regulating valve includes a body and a valve member. The valve member divides an inner side of the body into a pressure regulation chamber and an atmospheric pressure chamber, which is in communication with the atmosphere. The valve member is configured so that pressure of the pressure regulation chamber moves the valve member in a direction that changes a volume of the pressure regulation chamber. The pressure-regulating valve includes a cap that covers a portion of the body where the atmospheric pressure chamber is in communication with the atmosphere and a communication portion having a labyrinth structure and located between an inner surface of the cap and an outer surface of the body opposing the inner surface. The atmospheric pressure chamber is in communication with the atmosphere through the communication portion.

Abstract: A fuel supply system is configured to reduce the pressure of hydrogen gas delivered from a hydrogen cylinder by a high-pressure regulator arranged in series, regulate a flow rate of the pressure-reduced hydrogen gas by a hydrogen flow regulating device, and supply the hydrogen gas to a fuel cell. The high-pressure regulator includes a middle passage in which the hydrogen gas after being pressure-reduced by a first regulator and before being pressure-reduced by a second regulator enters, a rear passage in which the hydrogen gas after pressure-reduced by the second regulator enters, a communication passage allowing communication between the middle passage and the rear passage, and an internal air check valve provided in the communication passage and arranged to allow the hydrogen gas to flow in a direction from the middle passage toward the rear passage and block the hydrogen gas from flowing in a reverse direction thereto.

Abstract: To provide a novel mutilin derivative having a substitution at the 14-position, which is a novel mutilin analogue exhibiting a potent and broad antimicrobial action against Gram-positive bacteria and Gram-negative bacteria including various drug-resistant bacteria, and which is expected to be useful as an agent for treating infectious diseases. A mutilin derivative represented by the following general formula (1): or a pharmaceutically acceptable addition salt thereof.

Abstract: This invention is to present specific information necessary for maintenance of programs in an information system. This program analysis method includes: storing an entity that is an information unit as an object of a processing in a program into a relation table in association with an event affecting a processing for the entity; calculating importance degrees of the events by using data stored in the relation table; and identifying an event affecting a processing for a specific entity by using the data stored in the relation table, and calculating an influence degree of the specific entity by using the importance degree of the identified event. Because the user can grasp the influence degree of the entity, it becomes easy to grasp how much the update of the entity affects other portion in the information system.
