A propellant tank for storing a liquid propellant A and supplying vapor produced by evaporation of part of the liquid propellant A to an external location comprises a tank body for storing the liquid propellant A, a mesh member arranged inside the tank body to cover a liquid surface of the liquid propellant A to divide an interior of the tank body into a liquid propellant storing area LA and a gas storing area GA by utilizing surface tension of the liquid propellant, and a heater arranged to a gas storing area GA side of the tank body to keep the gas storing area GA at higher temperature than temperature in the liquid propellant storing area LA. The tank body has a propellant inlet open into the liquid propellant storing area LA and a gas outlet open into the gas storing area GA.

Disclosed herein is a recording apparatus including: an input section configured to input or generate main data and added data thereof; and a recording control section configured such that when the main data and the added data input or generated by the input section have each reached a predetermined data amount, the recording control section temporarily stores the main data and the added data in units of the predetermined data amount, that when the sum of the temporarily stored data has reached a specific write data unit, the recording control section transfers the temporarily stored data to recording media for recording thereto, and that when the amount of the temporarily stored data is less than that of the specific write data unit upon elapse of a predetermined time period since the most recent recording, the recording control section transfers the temporarily stored data to the recording media for recording thereto.
摘要:
A spark plug is provided which is constructed to ensure a higher degree of air-tightness. The spark plug includes a cylindrical metal housing within which an insulation porcelain is disposed. The housing has a hexagon head formed on an outer wall thereof and an annular chamber defined between itself and the insulation porcelain within which a sealing powder is disposed. The housing has an annular extension formed on the hexagon head. The annular extension is crimped inward to compress the sealing powder to enhance the air-tightness between the housing and the insulation porcelain. The annular extension has featured dimensions in order to ensure a desired degree of the air-tightness.

A rotation detecting device which detects the rotational state of a rotary shaft, is structured to be a device in which the number of parts is small, and the incorporation is simple. The structure is such that a long holder receiving part is formed on the channel back side in an opening part of a motor shaft case body of a casing which contains a reduction mechanism part, and a sensor holder in which a hall device, the rotation detecting device, is incorporated, is slid in the longitudinal direction of the motor shaft, and is incorporated in the holder receiving part in the lightly pressed state, similarly to the incorporation of the motor shaft.

A graded-refractive-index optical plastic material comprising an amorphous fluorine-containing polymer (A) having substantially no C--H bond, and at least one fluorine-containing polycyclic compound (B) having a refractive index higher by at least 0.005 than the fluorine-containing polymer (A), wherein the fluorine-containing polycyclic compound (B) is distributed in the fluorine-containing polymer (A) with a concentration gradient such that the concentration decreases in a direction of from the center to the periphery, and the fluorine-containing polycyclic compound (B) is at least one fluorine-containing polycyclic compound selected from the group consisting of the following compounds (B1), (B2) and (B3):(B1) a fluorine-containing non-condensed polycyclic compound having at least two fluorine-containing rings bonded by a bond containing at least one member selected from the group consisting of a triazine ring, an oxygen atom, a sulfur atom, a phosphorus atom and a metal atom, each of said fluorine-containing rings being a carbon ring or a heterocyclic ring and having a fluorine atom or a perfluoroalkyl group, said polycyclic compound having substantially no C--H bond;(B2) a fluorine-containing non-condensed polycyclic compound having at least three fluorine-containing rings bonded directly or by a bond containing a carbon atom, each of said fluorine-containing rings being a carbon ring or a heterocyclic ring and having a fluorine atom or a perfluoroalkyl group, said polycyclic compound having substantially no C--H bond;(B3) a fluorine-containing condensed polycyclic compound which is a condensed polycyclic compound composed of at least three carbon rings or heterocyclic rings, and which has substantially no C--H bond.
摘要:
In making a layer jump or focus search on a multilayer optical disk having two or more signal recorded layers, an objective lens is moved in a focusing direction to focus a laser beam onto a desired signal recorded layer with focus servo kept OFF. Based on the number of times a focus error signal having an S-shaped characteristic obtained as a result of driving the objective lens exceeds a predetermined voltage level, arrival at the desired signal recorded layer is determined. In this state, the focus servo is made active at the time when the focus error signal first goes to the 0 level.
摘要:
A seal system for a pressure vessel which includes a substantially rigid outer shell with at least one opening therein, an inner liner disposed within the outer shell against the inside surface thereof, an opening aligned with the opening of the outer shell and a boss disposed in the opening of the outer shell. The boss includes a neck portion for fitting in the opening of the outer shell, a flange portion extending outwardly from one end of the neck portion and having an upper surface and a lower surface, and a generally cylindrical hollow substantially aligned with the outer shell opening and having an inwardly projecting annular shoulder. The lip segment of the liner extends radially inwardly under the lower surface of the flange portion of the boss and then upwardly into the hollow of the boss, along the interior wall of the hollow until a portion of the lip segment rests on the shoulder.The seal system includes an attachment or coupling device having a generally cylindrical, downwardly extending lower insert section. The lower insert section includes an annular bottom wall in which is formed an annular recess opened downwardly. An upper head section is formed at the upper end of the insert section and includes a radially extending flange. The insert section is dimensioned to fit in and be received by the hollow of the boss above the shoulder. The seal system also includes a resilient O-ring for disposition in the recess of the insert section of the coupling device to protrude from the recess a sufficient distance to contact and seal against the lip section of the liner resting on the shoulder of the boss hollow, when the insert section is fitted into the hollow.
