Abstract: PROBLEM TO BE SOLVED: To provide a vaporizer capable of stably carrying out an operation of an engine without temporarily shielding feed of a gas fuel and diluting a concentration of air-fuel mixture at the time of snap action of a throttle valve. SOLUTION: The vaporizer V reduces a pressure to a predetermined primary pressure at a primary pressure reduction chamber and adjusts the pressure to a secondary pressure in the approximately atmospheric pressure state at a secondary pressure reduction chamber 36. A slow lock valve 28 for opening/closing a primary fuel deliver passage 27 is disposed at the delivery passage 27 opened from the primary pressure reduction chamber 22 and a slow lock pressure receiving chamber 30 divided by a slow lock diaphragm 29 for imparting an opening/closing operation force to the slow lock valve 28 and a suction passage 40 are communicated by a negative pressure introduction. A pressure control valve P is disposed at the introduction passage.  The pressure control valve P is divided to an upstream chamber PA and a downstream chamber PB and is communicated by a by-path passage 3 bypassing a valve hole 2 and a valve hole 2. A check valve 6 is disposed facing to the valve hole and opens the valve hole 2 when the negative pressure of the suction passage 40 acting on the upstream chamber PA is a constant value or higher and it closes the valve hole when the negative pressure is a constant value or lower. A control orifice 7 is disposed at the by-path passage 3 and the upstream chamber PA and the downstream chamber PB are always communicated by the control orifice 7.

Title: Liquid chromatograph-mass spectrograph
Inventor: TANAKA YASUFUMI
IPC: H01J49/04
Filed: 2001-10-01
Abstract: PROBLEM TO BE SOLVED: To obtain high sensitivity over a wide mass range. SOLUTION: A desolvation pipe 23 which communicates an atomization chamber for atomizing a sample liquid under an atmospheric pressure and an intermediate vacuum chamber in the post-stage is formed by arranging a first and second metal pipes 231 and 232 having different inner diameters in contact side by side. Moreover, the part having a larger inner diameter is given a larger pipe length so as to give pearly equal flow resistance to both pipes 231 and 232. Under the same application voltage, ions having a relatively high mass pass more in the pipe having a small inner diameter, while ions having a relatively low mass pass more in the pipe having a larger inner diameter. Therefore, with the configuration of the desolvation pipe 23, many ions can be transported to a later stage without bias from a low mass region to a high mass region.

Title: Receiving signal processing circuit and method therefor
Inventor: MORIMOTO TAKESHI
IPC: H04B1/10
Filed: 2001-10-02
Abstract: PROBLEM TO BE SOLVED: To enable elimination of noises mixing from a receiving section with a small circuit. SOLUTION: If a remote-control signal is inputted into a light-receiving section 110, upon detecting a header by a header detecting circuit 120, a mask pulse generating circuit 130 generates a mask pulse 13. At this time, even if noises are mixed into an output from a light-receiving section 210, since the noises are masked by the mask pulse 13 in an output from an AND circuit 330, only the signal 32 after being masked being an output from an AND circuit 320 is reflected on an extracted signal of an output from an OR circuit. Here, only the input signal 11 is inputted into the circuit 320 because a mask pulse 23 is not generated, and accordingly, the signal 32 contains only the information of the signal 11. Further, since only the pulse 13 and the signal 11 are inputted into an AND circuit 310, a signal 31 after being masked is masked like the signal 33.

Title: Gas compressor
Inventor: KUWABARA OKIKAZU
IPC: F04C29/02
Filed: 2001-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a gas compressor which can reduce a power, improve durability and reduce vibrations and noises by minimizing a centrifugal force of a vane. SOLUTION: A magnesium alloy is used as a base material of a vane 13. The surface of the vane is plated with electrolytic nickel or non-electrolytic nickel, for preventing abrasion of the vane. Under such a construction, compared with the conventional aluminum alloy vane 13 widely used, the centrifugal force generated can be reduced by specific gravity ratio (to about two-thirds) of the base material. Accordingly, a pressing force of the vane 13 to a cylinder 4 is reduced, so as to improve abrasion durability. Thereby, it is made possible to manufacture a practical vane 13.
