Title: Vibration prevention mechanism
Inventor: DEGUCHI HIROYUKI
IPC: G03G15/00
Filed: 1991-11-29
Abstract: PURPOSE:To provide a vibration prevention mechanism capable of preventing to the utmost, deterioration of an elastic member for moderating vibration from a vibration source to a fixed member to fix this vibration source and certainly restraining transmission of vibration to the fixed member. CONSTITUTION:In a vibration prevention mechanism 1, a motor support plate 3 and an elastic member 5 for a motor 2 which is a vibration source, an installation plate 4 and an elastic member 5 to fix the motor 2 and a fixing plate 9 are sequentially and flatly piled up, and each of them is sandwiched and tightened by an installation vis screwed in the female screw part 14 of the fixing plate 9 through a vis insertion hole or an insertion hole 7. Consequently, stress applied on each of the elastic members 5 is comparatively small. Additionally, as a cylindrical part 6 erected on the elastic member 5 goes toward the other elastic member 5 through a cut-off part 10 formed on the installation plate 4, the installation vis 8 inserted into the insertion hole 7 of the cylindrical part 6 and the installation plate 4 both of which are rigid bodies do not directly make contact with each other.

Title: Continuous extruding pelletizer
Inventor: OIDA NAOHISA
IPC: B29C48/05
Filed: 1991-11-29
Abstract: PURPOSE:To conduct continuous pelletizing efficiently and to prevent dust generation in molding and tablet preparation by arranging a screw shaft and the head face of a flight on the same level and increasing the flight height to the screw shaft by decreasing the diameter of the screw shaft toward its head. CONSTITUTION:The screw shaft head face(s) 3 and the screw flight head face(s) 3' of a single or double screwed extruding pelletizer are arranged on the same level, and the diameter of the screw shaft is decreased toward its head so that the flight 2' height is increased to the screw shaft. The head part of the screw is a 4-streaked screw type, and a die 5 has a straight hole 6 from its inlet to outlet. The clearance 9 between the head face 3 and the die 5 is 1mm or less. Since the clearance 9 being 1mm or less, material can be discharged quickly by the screw rotation, and the die pulsing is prevented. Since the size of the screw head face is small, the discharge per unit time can be increased by installing a number of die holes.

IPC: H01Q13/08
Filed: 1992-11-26
Abstract: PURPOSE:To provide a plane antenna which owns a moisture eliminating function by forming a water-repellent processing layer at least on the exposed surface of a ceramic dielectric. CONSTITUTION:A microstrip antenna holds a ceramic dielectric 2 between a radiation electrode 4 and a ground electrode 3 and also has a water-repellent processing layer at least on the surface of the dielectric 2. It is desirable to use an organic resin layer having the water absorbing rate of 1% or less to the water-repellent processing layer. Thus the dielectric 2 contains a water- repellent processing layer which can repel the waterdrops of the rainwater, etc. Therefore the specific dielectric constant of the dielectric 2 is stabilized and the center frequency is also stabilized. When the water-repellent processing layers are provided on each surface of both electrodes 3 and 4, the oxidation of the metals of these electrodes can be prevented. Thus it is possible to prevent the deterioration of characteristic due to the oxidation of the electrodes 3 and 4 and to improve the reliability of a plane antenna.
