Title: Method for manufacture of valve sleeve
Inventor: KAGIKAWHA HIROMI
IPC: B62D5/083
Filed: 1984-04-04
Granted: 1988-04-19
Abstract: A hoolw cylindrical casing with one closed end is produced by forging.  By means of a tapered punch and die pressing the upper part of the open end of the cylindrical casing is expanded outwards to form a conical opening.  (2) The internal grooves are cut by means of a downward stroke of a broaching tool.  Due to the tapered opening of the casing the cutting edges of the broaching tool engage and commence the cut to a short distance from the open end.  The stroke of the broaching cutter is set to terminate the groove before reaching the closed end. (3) A cylindrical punch fitting in the grooved bore forces the casing through a circular die to straighten out the tapered upper section.

Title: Fm receiver with noise su££ression during rayleigh faded received signals
Inventor: EASTNOND BRUCE C
IPC: H04B1/10
Filed: 1987-12-03
Granted: 1995-10-23
Abstract: An improved FM communication system is disclosed in which noise bursts and pops in the audio output of the receiver, due to weak and Rayleigh-faded signals, are minimized by selectively attenuating the audio signal in the receiver. The amount and rate of attenuation for the receiver noise reduction circuits is determined by a control signal derived form either the average discriminator noise at frequencies above 3 kHz, or from a received RF signal strength indicator, or a combination of both. The audio output is attenuated during weak signals or Rayleigh fades only when the attenuation control signal increases above a predetermined signal-to-noise ratio threshold. Also described are further improvements to noise attenuation devices used in combination with the receiver noise reduction circuits to enhance audio quality in particular applications, e.g., FM repeater systems which may incorporate multiple transmitters in a simulcast configuration.

Abstract: 본발명은 더블 메탈 콘택방법에 관한 것으로, 종래의 방법에서 IMD 형성공정이 복잡하고 신뢰성이 저하되는 문제점을 해결하기 위한 것이다. 
     즉, IMD 형성공정에 마스크공정을 쓰지 않고 신뢰성을 저하시킨 SOG를 사용하지 않았다. 이와같은 공정방법은 기판에 금속을 증착하여 포토 레지스트를 이용하여 식각공정으로 제 1 금속라인을 형성하는 공정과, 상기 제 1 금속라인과 포토 레지스트를 측벽에 측벽절연막을 형성하고 포토 레지스트를 제거하는 공정과, 전면에 IMD 절연막을 증착하고, 셀프 얼라인 VIA 콘택을 형성하는 공정과, 제 2 금속을 증착하는 공정으로 이루어진다. 
     따라서, 공정이 단순해지고 신뢰성 향상 및 수율이 증가된다.

Title: Process for the preparation of oxybenzene derivatives
Inventor: PARK SANG-HU
IPC: C07C205/34
Filed: 1991-12-27
Granted: 1995-02-15
Abstract: 2,3-Dihalo-6-nitro substd. oxybenzene cpd. of formula (I) to be useful as an intermediate for preparation of quinoline based antibiotics, is prepd. by: reacting the cpd. of formula (II) with propagyl alcohol in the presence of the basic cpd. in an organic solvent to prepare the cpd. of formula (III) as the intermediate; and then preparing the oxybenzene deriv. (I). In the process, the org. solvent is one or more mixt. of benzene, toluene, halomethane or tetrahydrofuran; the basic cpd. is alkali metal fluoride, alkali (earth) metal hydride, alkali metal carbonate or basic org. solvent cpd.. In the formulas, X1,X2,X3 are halogen.
