Title: Disk-cone antenna
Inventor: KOBUCHI TOMOKI
IPC: H01Q9/40
Filed: 1988-04-15
Abstract: PURPOSE:To make the title antenna catch a high bend with a high radiation efficiency and, at the same time, stably operate even in severe temperature environment by causing the peripheral part of a disk only to come into contact with a dielectric support and respectively coupling the peripheral part and a cone with the support by means of screws. CONSTITUTION:A disk 7 is coupled with a cone 8 having a conical shape through a dielectric support 9. The disk 7 and cone 8 are respectively coupled with the support 9 by means of screws. Namely, the disk 7 and cone 8 are respectively fixed to the support 9 by means of male screws 12 and 13. Moreover, the leading end section of a coaxial line 11 for RF feeding is soldered to the central part of the disk 7. Therefore, even when the frequency rises to >=2 GHz, the dielectric loss hardly increases and the radiation efficiency does not drop, and thus, high-band characteristics are obtained. In addition, this antenna stably operates even under conditions where temperature fluctuation is severe.

On the outer peripheral surface 1b of the rotary drum 1 a roller 4 made of a flexible material such as a rubber, a soft resin material or the like is brought into contact with the outer peripheral surface 1b of the rotary drum 1. The roller 4 is baked and bonded at its central part with a steel pipe 5, to which a shaft 7 rotated by means of a motor 6 is fitted and fixed. At both end surface sides of the roller 4, there are formed concentric slits 4b, and flexible lips 4c between the slits 4b, and flexible lips 4c are formed between the slits 4b and the outer peripheral surfaces 4a. By this arrangement, at the time of rotating the roller 4, the lip part 4c is enlarged by the centrifugal force to increase the press-fitting force to the drum 1.

Title: Caterpillar type cable supporter
Inventor: IMAI MASAYASU
IPC: H02G1/02
Filed: 1989-04-14
Abstract: PURPOSE:To improve travelling performance of a chain body by fitting travelling wheels to the side of a segment main body and by positioning the bottom of a guide groove of the segment main body on the supporting body side rather than the pivoting axis of the travelling wheels. CONSTITUTION:The load W from a segment 2 is evenly shared by the 1st roller 30 and the 2nd roller 32 evenly in pressure contact with the segment 2. The load imposed on the 2nd roller is reduced in interpolating the ratio of a span S to a span S' on the principle of a lever by an arm main body 31 and transmitted to a load cell 33. As the vertical distance between the contact to a supporting body 4 of a travelling wheel 12 and the bottom of a guide groove 10, the acting region by the load of a cable, is small, the moment by traverse load becomes so little that the travelling wheel will undergo less influence of the traverse load.

Title: Speed reducer for outboard engine
Inventor: AOKI DAISUKE
IPC: F16H3/14
Filed: 1978-07-31
Abstract: PURPOSE: To make the moving speed of a boat low enough for trawling, by transmitting the turning force of a driving shaft to a propeller shaft through a planet gear mechanism to render the speed of the propeller shaft lower than that of the driving shaft.  
     CONSTITUTION: The turning force of the driving shaft 3 is transmitted to a sun gear 34 and then to a planet gear 32 so that the planet gear revolves between the sun gear 34 and a ring gear 29 while rotating. The revolving force of the planet gear 32 is transmitted to the propeller shaft 5 through a support plate 30 to rotate the propeller shaft forward. The speed of the propeller shaft 5 is thus rendered sufficiently lower than that of the driving shaft 3. Therefore, the rotational frequency of a propeller is reduced as that of an engine is kept in a stablle rotation range.

IPC: B41J2/01
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To reduce contamination inside an ink-jet printer due to ink aerosol generated when ink is discharged in the printer. SOLUTION: This device is designed such that ink 74 discharged from a nozzle 68 is electrostatically charged by keeping ink inside an ink chamber 64 electrostatically charged by applying an electric field thereto. Since aerosol particles separated from discharged ink are caused to spring toward a nozzle side or attracted toward a print medium side through an electric field kept applied between the nozzle 68 and the print medium, the aerosol particles are prevented from floating inside the printer.

Title: Information transfer method
Inventor: KAMO KOSUKE
IPC: G06F13/42
Filed: 1985-05-02
Abstract: PURPOSE:To promote the changeover between the transmission and the reception by transmitting the transmission/reception changeover signal in place of the return information in case no information to be returned is available when the information is transferred between two devices having just a 1-way function respectively. CONSTITUTION:A transmission/reception device 1A contains a reception circuit 2A which receives the information from a device 1B at the remote side and an information transmission circuit 6A. A transmission presence/absence monitoring circuit 4A monitors the presence or absence of a stop signal sent from a transmission detecting circuit 3A. When no stop signal is detected, i.e., the information to be returned in not available, the circuit 4A sends the transmission/reception changeover signal to a transmission request list 5A. The list 5A sends the transmission/reception changeover signal to the circuit 3A in the form of the return information. Then the circuit 3A starts the circuit 6A to send the transmission/reception changeover signal to the device 1B. Thus the transmission/reception changeover is carried out within a fixed period of time. Then the continuous transmission is possible.
