Title: Suction system for supercharged engine
Inventor: OKIMOTO HARUO
IPC: F02B29/06
Filed: 1984-04-23
Abstract: PURPOSE:To make improvements in charging efficiency at a high-speed range, by specifying the length of a passage at the downstream of an expansion chamber in a main suction passage in particular, in case of a device installing a timing valve, whose opening or closing timing is advanced in proportion as it changes from a low-speed range to the high-speed one, in the downstream of a supercharger in a supercharging passage. CONSTITUTION:A suction passage is branched off into a main suction passage 12 and a supercharging passage 13 from its midway, while a throttle valve 17 and an expansion chamber 18 both are installed in this main suction passage 12. On the other hand, a vane type supercharger 20, a supercharged air control valve 22 and a timing valve 23 are all installed in the supercharging passage 13. The timing valve 23 is controlled so as to be advanced in proportion as its opening or closing timing changes from a low-speed range to a high-speed one. In the above-mentioned, at the high-speed range that an engine 1 is more than about 4,000 r.p.m., the length of the main suction passage 12 at the more downstream than the expansion chamber 18 is set so as to cause a compressional wave to be added to the vicinity of a main suction port at suction stroke closing time by means of a suction inertial effect. With this constitution, the prefiring of supercharged air at the suction stroke closing time is prevented from occurring, thus charging efficiency is improved.

Patent JP-S5510232-A (JP)
Title: Circular curved waveguide unit
Inventor: ABE HISASHI
IPC: H01P1/161
Filed: 1978-07-07
Abstract: PURPOSE:To improve a degree of cross polarization discrimination by reducing the coupling between polarized waves by providing a circular curved waveguide with a phase shifter which reduces a phase difference between two orthogonal polarized waves generated and a cross polarization compensator which cancels a cross polarization component. CONSTITUTION:In circular curved waveguide 1, since the phase of a y-polarized wave leads that of a x-polarized wave, the phase of (y)-polarized wave is delayed by setting dielectric plate 3 of phase shifter 2 in parallel to the electric field of the (y)-polarized wave, thereby making the (x)-polarized wave nearly in phase with the (y)-polarized wave at the output of phase shifter 2. In this way, the generation of elliptic polarized waves is suppressed and a cross polarized wave generated depending upon the work accuracy of waveguide 1 and phase shifter 2 is canceled by using cross polarization compensator 4 composed of a circular waveguide capable of generating the reverse cross polarized wave component of it. Consequently, the cross polarization discrimination will be improved by adding a phase shifter and cross polarization compensator.

Title: Apparatus for inspecting moisture of closed space body
Inventor: ISHIKAWA KUNIO
IPC: G01N7/14
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To simply and easily inspect the presence/absence of moisture in a closed space body by measuring a change of a pressure detection value when steam in the closed space body is adsorbed by a moisture adsorber. SOLUTION: An opening-closing valve V1 is opened to vacuumize the interior of a moisture adsorber 4 through a vacuum pump 5. Then, the opening-closing valve V1 is closed and closed space bodies 3a, 3b are vacuumized through the vacuum pump 5. The opening-closing valve V1 is opened upon necessities, for instance, after the bodies are vacuum dried. The steam in the bodies 3a, 3b are adsorbed by the moisture adsorber 4 having a moisture adsorbent. At this time, if the moisture is not present in the closed space bodies 3a, 3b, a pressure measured by a vacuum gauge 6 shows no change. On the other hand, if the moisture is present, the moisture is turned to steam and adsorbed by the moisture adsorbent of the moisture adsorber 4 and consequently the pressure decreases.  The presence/absence of the moisture in the closed space bodies 3a, 3b can be easily detected from this decrease of the pressure.
