Title: Hydraulic control valve
Inventor: KOBAYASHI MASANORI
IPC: B62D5/083
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To effectively control cavitation in restricting parts arrenged on a fitting periphery between a valve body and a valve spool so as to reduce fluid sounds by forming the drawing parts in both sides an oil groove connected to a hydraulic oil source to have areas larger that those of restricting parts in both sides of an oil groove connected to an oil exhaust side. SOLUTION: Lands between oil grooves 5 and 5,..., in a valve spool 2 side are offset-arranged and restricting parts 6a and 6a in both sides of an oil supplying room 10 are formed to have restricting areas larger than those of restricting parts 6b and 6b in both sides of an oil exhaust room 11. This size relationship is maintained during an operating state and the drawing part 6a between the oil supplying room 10 and the oil discharging room 13 is formed to have a restricting area lager than that of the drawing part 6b between an oil sending room 12 and the oil exhaust room 11. Thus, the flowing of hydraulic oil from the oil supplying room 10 to the oil exhaust room 11 is concentrated in the drawing part 6a between the oil supplying room 10 and the exhaust room 13 as a good condition against cavitation and thereby the generation of cavitation is effectively controlled.

Title: Dielectric resonator
Inventor: NISHIKAWA TOSHIO
IPC: H01P7/10
Filed: 1982-10-18
Abstract: PURPOSE:To obtain the temperature characteristics with a good resonance frequency by using dielectric materials of the same linear expansion coefficient to form a cas and a columnar dielectric material and forming a conductive film on the inner or outer surface of the dielectric material. CONSTITUTION:A dielectric resonator 10 consists of a columnar dielectric material part 11 of a linear expansion coefficient alpha and a dielectric case part 12 having the same coefficient alpha and containing said part 11. A conductive film 13 is formed on the entire inner surface of the part 12. Thus the film 13 functions as a metallic case of the resonator 10 and also serves the shielding and real current routes. The part 12 is divided into a case upper part 121 and a case main body part 122. In this case, a joint exists at the boundary between the parts 121 and 122. Therefore the case 12 is not continuous at the joint area. While the film 13 is continuous even at an area where the inner surface of the cover 121 crosses the inner surface of the part 12. As a result, the real current route has no joint and therefore the Q of the resonator 10 is never deteriorated.
