Title: Curable bladder composition containing alkylphenoxy- poly(alkyleneoxy)alkanol
Inventor: PATITSAS GEORGE PHILEMON
IPC: B29C35/02
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce adhesive properties of a cured tire by adding and dispersing an alkyleneoxyalkanol containing a specific weight ratio of an alkyl group and an alkyleneoxy group having specific number of carbon atoms to and in a curable bladder compound of an isobutylene copolymer, and crosslinking a bladder rubber. SOLUTION: An alkyleneoxyalcanol is added to and dispersed in a curable bladder compound originated from a copolymer of an isobutylene, and then a bladder rubber is crosslinked. An alkyl group of the alkyleneoxyalkanol has 6 to 12 carbon atoms, and an alkyleneoxy group has 2 to 3 carbon atoms. A rubber-like polymer is a copolymer of an isoolefin and a paralkylstyrene, and its 2 to 15 wt.% is a paramethylstyrene. The curable bladder has good lubricity and releasing characteristics from a cured hydrocarbon rubber. Thus, adhesive properties of an inner liner of the cured tire to the bladder can be lowered.

Title: Pressure controlling solenoid valve
Inventor: KAMIYA KINGO
IPC: F16K31/06
Filed: 1988-09-29
Abstract: PURPOSE:To maintain the linear output characteristic of the fluid pressure by the duty-control by constituting the title device so that a spherical valve body shitts in stable ways between two valve seats, and by directly driving the spherical valve body by a solenoid. CONSTITUTION:Since a spherical valve body 4 slides in a cylinder 2a and is guided by the inner wall surface of the cylinder, said spherical valve body 4 is surely seated onto the first valve seat 21S and the second valve seat 22S, and the stable operation is repeated. Therefore, when the pressurized fluid is supplied through an input port 6, and a discharge port 8 is opened to the atmosphere, the output fluid outputted from an output port 7 is pressurized when communicating to the former, and decompressed when communicating to the latter. When the conduction current of a solenoid 12 is duty-controlled with a prescribed cycle, the pressure increase and decrease of the output fluid of the output port 7 are repeated by the spherical valve body 4 consisting of a magnetic body which shifts between the first and second valve seats 21S and 22S according to the electric conduction, and a pressure proportional to the duty ratio is maintained.

Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent a failure in shaping and prevent contents from leaking, a body from swelling due to intrusion of oxygen gas from an exterior, the contents from being oxidized, etc., by making two longitudinal rules approximately parallel to each other, which are positioned on a folding panel on the bottom of a paper container. SOLUTION: For example, the paper container is formed by having a laminate subjected to printing, creasing, cutting or the like to prepare a blank sheet as shown in the figure, and by applying frame seal machining or the like to make into a sleeve-like form, and then by shaping into the paper container by a filling and shaping machine. An intersection (r) of a slant rule 4 and a tip of a lateral rule 5 is positioned closer to a point (s) being a tip of the slant rule 4 than an intersection (q) of a tip of a longitudinal rule 7 and the other tip of the two slant rules 4.  Thus the two longitudinal rules 7 positioned on a folding panel 10 on the bottom are approximately parallel to each other, thereby preventing the vicinity of a point (p) positioned at a tip of the folding panel 10 from being overlapped so as to prevent a failure in shaping from occurring and contents from leaking or the like.

Abstract: PURPOSE:To eliminate the apparent gain reduction and to execute a low noise MMIC by turning on and off the section between the differential output edges of a differential amplifier composed of first and third switching elements with the period of a local oscillation signal by a fourth switching element. CONSTITUTION:FET31-33 constitute a differential amplifier. Between the drain terminals of FET31 and 32, an FET34 is provided. When to a gate terminal 14 of the FET34, a local oscillation signal LO is impressed, the FET34 executes the ON and OFF action at the period of the local oscillation signal LO, and when the FET34 is the OFF condition, a signal inputted from a terminal 13 flows at the route of a current 42 and is outputted from an output terminal 41 to an LPF12 by a load resistance 36. Next, when the FET34 is the ON condition, a current 42 is switched to the route of a current 43 and nothing is outputted to the output terminal 41. An output voltage VOUT is modulated in a rectangular wave shape at a duty 50% by the local oscillation signal LO, and an IF signal SO is removed from an output terminal 15 through the LPF12. The gain of the amplifier is not changed by the excitation of the local oscillation signal LO and the apparent reduction of the gain is not executed.

Filed: 1990-09-18
Abstract: PURPOSE:To provide an inexpensive and hygienically preferable high pressure treatment device enabling to feed a raw material thereinto without the overflow of the raw material, by disposing a free piston in the pressing chamber of a high pressure tank. CONSTITUTION:A raw material is fed from a piping 32 into a pressing chamber 23 through a lower lid 21, and a free piston 50 is simultaneously pressed up by the raw material. Air in the pressing chamber 23 is released in the atmosphere from a piping attached to an upper lid 22 through a valve 69. When the pressing chamber 23 is filled with the raw material, the free piston is tightly brought into contact with the upper lid 22 to close an air-discharging pipe 6. It is thereby detected that a pressure in the pressing chamber reaches a prescribed pressure, and a pump for feeding the raw material is stopped to stop the feed of the raw material. The raw material is pressed by the action of a converter in the pressing chamber, held in the chamber for a prescribed time, subjected to the reduction of the high pressure and subsequently discharged from the high pressure tank.

Abstract: PURPOSE:To enable always observation of film-forming condition of grown film surface of a crystal grown by the molecular beam in the titled device provided with an electron gun and a fluorescent surface by providing also a shutter and a Faraday cup to the front of the fluorescent surface. CONSTITUTION:When, for example, a GaAs crystal is grown on the surface of a substrate 2 arranged to the inside of the titled device 1, crucibles 3, 4 serving as a molecular beam source is heated by a resistance heating device 5. Further, a reflection type fast electron diffraction device provided with an electron gun 6 and a focusing lens 7 is installed by which electron beams reflected by a plate 2 form an image of electron on the fluorescent surface 9. A shutter 11 and a Faraday cup 12 are provided in front of the surface 9. While the diffraction pattern of the reflected beam is observed always by the fluorescent plate during the growth of a crystal, the fluorescent plate is contaminated by As. Accordingly, when the thickness of grown film is monitored by said diffraction pattern, observation is executed prior to the commencement of growth by opening the shutter 11 to execute initial observation and the reflection at the mirror surface and the position of a spot of diffraction are detected. The cup 12 is then moved to the position of the spot, and the shutter 11 is closed. During the growth of the crystal, the observation is proceeded by the detection of the intensity of periodical signal of the above-described reflected beam using the cup 12.
