Title: Ultrahigh purity gas flow control valve having closed bellows
Inventor: MAAKU EI KEINAN
IPC: F16K41/10
Filed: 1990-04-11
Abstract: PURPOSE: To reduce the leakage rate of gas to prevent contaminating particles from entering gas flow by providing a second valve seat which is pressed into engagement by a valve seat seal member when the valve seat seal member is in a fully open position, thereby sealing a chamber in which a bellows is enclosed against a gas flow path. CONSTITUTION: An ultrahigh purity gas flow control valve has a gas flow path 14 through which passage bore gas flow is passed and a valve rod receiving bore 18 crossing the gas flow path 14 at an acute angle. The upper end 36 of a bellows 26 is welded to a cap 38 to constitute a sealing lid for the space between the bellows 25 and a bonnet 16. A first space is an unsealed space communicated with ambient air although being isolated from a sealing system including the gas flow path 14 through which the gas flow passes in a space within the bellows 26. A second space 46 is a space within the bonnet 16 between the interior wall of the bonnet 16 and the outer periphery of the bellows 26 and communicated with the sealing system including the gas flow path 14 through which the gas flow passes.  The lower end of the bonnet 16 is such that a valve seat seal member 24 is pressed into contact with a second valve seat 44 when the valve is held in a fully open position.

Title: Bumping accident judging circuit
Inventor: KIN KAZUYOSHI
IPC: B60R21/00
Filed: 1993-04-21
Abstract: PURPOSE:To improve the extent of accuracy for an impact judgment as well as to reduce any possible malfunctions by installing a noise controlling means which adds a restriction to an acceleration signal to be fed to a judging means at a time when acceleration working in the opposite direction to a movable body out of the extracted accelerating constituents has exceeded the specified value. CONSTITUTION:When a plastic bumper is broken by a light or medium impact or the like, by way of example, and a large negative acceleration is superposed on an acceleration signal out of an acceleration sensor 1 and thereby it is fed to a delay circuit 40 and a threshold circuit 41, it is compared with the threshold value set to this threshold circuit 41, and if exceeding the threshold value, in the meantime, a high level signal is fed to a monostable multivibrator 43, and both input-output intervals of a high level switch circuit 42 is opened as long as the specified time. In consequence, a signal attending on vibrations just after the breakdown of the plastic bumper is eliminated, therefore only the acceleration signal with no noise is fed to a square-law circuit 21, so that the acceleration signal is integrated in a state of no noise by an integrating circuit 22.

Title: Electrostatic recording body
Inventor: TAKAHASHI SHINICHI
IPC: G03G5/02
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain an electrostatic recording body having the reproducibility of high-quality solid parts sufficiently dealable with color recording as well by incorporating hydrophobic silica into a recording layer. SOLUTION: The hydrophobic silica is incorporated into the electrostatic recording body formed by successively laminating a conductive layer and a recording layer on at least one surface of a base. In such a case, the hydrophobic silica to be used is formed by treating the silica by an org. compd., thereby imparting a hydrophobic property to the surface of the silica which is intrinsically hydrophilic. The more specific examples of the org. compd. to be used for the treatment for imparting the hydrophobic property include silicone compds., such as dimethylbutyl methoxysilane, dimethyl 2-ethylhexyl methoxysilane, dimethyloctyl methoxysilane, isobutyl trimethoxysilane, n-decyl trimethoxysilane, and fluorine denatured silicone oil, but are not limited thereto. The proper combination use of >=2 kinds of these silicone compds. is equally possible.

IPC: H03G3/10
Filed: 1985-05-02
Abstract: PURPOSE:To obtain a gain variable amplifier having linear I/O characteristics and a wide input allowable range by using a differential amplifier as a current distributor, connecting the 1st load to one output terminal and connecting the 2nd load to the current adding point of the diferential amplifier. CONSTITUTION:A voltage source 6 is used as a power source of the circuit. A current proportional to an input voltage to an input terminal is generated by a pnp transistor (TR) 3 and a resistor 7 and distributed to npn TRs 1, 2 by voltage sources 4, 5. The gain variable width of the gain variable amplifier can be optionally set up by the values of resistors 8, 9. Since the differential amplifier is used as the current distributor, the distortion of I/O characteristics which may be generated due to the enter of the differential amplifier to a non-linear area can be suppressed. The input allowable range is determined by the voltage sources 4, 5 and is not restricted by the gain of the gain variable amplifier.

Filed: 1992-04-15
Abstract: PURPOSE: To suppress noises in a brake operation by allowing a pawl to interact with a member provided between fixing teeth and its rotational pin and dimensioned to slide over sector teeth in operation of a lever, and simultaneously keeping the fixing teeth away from the sector teeth in that time. CONSTITUTION: This handbrake is operated by applying transverse force F to a lever 5 to incline it upward. In this operation of the lever 5, an end part of a tooth 17 keeps contact with a middle/upper part of sector teeth 2 with sliding to keep teeth 13 away from the sector teeth 2. When the rotation of the lever 5 is completed and force generated in the lever 5 by a user is released, the tooth 17 meshes with the sector teeth 2, and in association with it, the teeth 13 mesh with the sector teeth 2 in a position where the brake is fixed. Because the tooth 17 is made of an appropriately selected plastic, the tooth 17 slides over the sector teeth 2 with no noise.
