Title: Rudder of ship
Inventor: NAKAMURA AKIO
IPC: B63H25/38
Filed: 1990-03-14
Abstract: PURPOSE:To facilitate maintenance and inspection of the propeller of a propeller propulsion ship with a rudder of simple constitution by integrating a pair of rudder plates together at their lowest end portions in their cross direction, and holding the rudder plates while upwardly enlarging the space therebetween, and allowing the rudder of the propeller propulsion ship to be freely rotated about one rudder shaft. CONSTITUTION:Two rudder plates 2, 3 are integrated together at their lower end edges and formed into V-shaped cross section and are connected and integrated together at their upper end edges by a reinforcing plate 4. A vertical fin portion 5 is provided at the respective lower end portions of both rudder plates 2, 3 and has its rear end curved at a predetermined angle to the direction of rotation of a propeller. The peripheral portion of the reinforcing plate 4 is extended outward from the rudder plates 2, 3 to form a horizontal fin portion 6. A rudder shaft 7 is mounted on the reinforcing plate 4 so that a rudder 1 is freely rotated. By this constitution the rudder itself is miniaturized with simple constitution and disposed near a ship body and thereby maintenance of the propeller is facilitated.

Title: Breather for fuel tank
Inventor: IIMORI TAKAYUKI
IPC: B60K15/035
Filed: 1985-03-28
Abstract: PURPOSE:To prevent inner pressure rise of tank effectively by providing two breather paths for communicating the upper space in fuel tank to the atmosphere then arranging a gate valve in one path while a plug body made of sintered material having countless fine holes in the other path. CONSTITUTION:In a portable engine generator 1, the fuel tube 7 and the first breather tube 17c are brought into conductive condition upon opening of a fuel cock 8, to lead in the atmospheric pressure into a fuel tank 6 through the tube 17c and the communication tubes 15a, 15b. Consequently, the fuel in the fuel tank 6 is fed through a fuel tube 7 to a carburetor 4a. Upon stoppage of engine 4, the cooler will also stop to temporarily increase the engine temperature thus to heat the fuel tank 6. Consequently, upon increase of the inner pressure of tank, the air in the tank is discharged through the communication tubes 15a, 15b, second breather tube 17d, countless fine continuous holes in the plug body 18 made of sintered material and a filter 19 resulting in suppression of inner pressure rise.

IPC: H02K15/12
Filed: 1982-04-20
Abstract: PURPOSE:To remove air, moisture, etc. in an insulating layer by previously forming a groove in the longitudinal direction to the surface of a transposition filler before the insulating layer is formed. CONSTITUTION:Force pistons 5 with projections in the longitudinal direction are pushed in the direction of the arrow A from the surfaces of the transposition fillers 2, both side surfaces of conductor sections 3 are also pushed by the force pistons, and the conductor sections 4 are molded while the grooves 10 in the longitudinal direction are formed to the surfaces of the transposition fillers 2. An insulating tape is wound on the conductor sections 3, and the insulating layer 4 is formed. A thermosetting resin is impregnated under vacuum and pressure, and heated and cured under pressure. Accordingly, air, moisture and a solvent can be removed not only from the outside of the insulating layer 4 but also through the grooves 10 because the grooves in the longitudinal direction are formed to the surfaces of the transposition fillers 2.

Abstract: PURPOSE:To prevent a short-circuit between source and drain regions and a Schottky gate electrode by a method wherein an impurity is ion-implanted to form the source and drain regions and after a film is formed thereon, heat treatment is performed to activate the impurity. CONSTITUTION:Si ions are selectively implanted in a GaAs substrate 1 and thereafter, heat treatment is performed to obtain an n-type layer 3. Then, a TiWSi alloy film is adhered and is etched to form a gate electrode 4. Subsequently, Si is ion-implanted suing an SiO2 film 5 formed selectively and the electrode 4 as masks and after that, the film 5 is removed and an SiO2 film (not shown in figure) for preventing an out diffusion is newly formed.

Abstract: PURPOSE:To prepare the title material having excellent electrical properties in a high-frequency region along with a high heat resistance by compounding a compsn. comprising a polyphenylene oxide, a crosslinker, and an initiator with an inorg. filler, an org. fiber, and an inorg. fiber. CONSTITUTION:A compsn. comprising a polyphenylene oxide [e.g. poly(2,6- dimethyl-1,4-phenylene oxide)], a crosslinker (e.g. triallyl isocyanurate), and an initiator (e.g. Perbutyl P) is compounded with an inorg. filler (e.g. CaCO3), an org. fiber (e.g. pulp), and an inorg. fiber (e.g. glass fiber) to give the title material, which gives a molded article exhibiting excellent electrical properties in a high-frequency region because of low dielectric constant and dielectric dissipation factor inherent in the polyphenylene oxide. The polyphenylene oxide compounded is crosslinked by the crosslinker to give a highly heat-resistant crosslinked polymer, and the inorg. filler, org. fiber, and inorg. fiber compounded strengthen the resistance to heat distortion, thus giving a molded article with a high heat resistance.

Abstract: PURPOSE: To prevent a control signal from being extracted erroneously, by fetching the control signal only when a vertical synchronizing pulse and a control pattern are extracted from an input signal.  
     CONSTITUTION: Horizontal and vertical synchronizing signals 27 and 34 are obtained from the synchronizing signal, which is obtained by separating input video signal A, by horizontal synchronizing signal generating circuit 20 and vertical synchronizing signal generating circuit 32, and first, signal 27 is counted by recording address counter 35, and simultaneously, synchronizing signal 40 is input to shift register 22 in circuit 32 by prescribed shift clock 20. The parallel output signal of register 22 is input to deciding circuit 24 where a prescribed pattern is set, and circuit 24 outputs output 25 only when the synchronizing signal pattern agrees with the vertical synchronizing signal pattern. In case that output 25 is not output within a prescribed time, it is detected by detecting circuit 26, and false vertical synchronizing signal 28 delayed by shift register 29 is selected in selecting circuit 30 by detection output 15 and becomes vertical synchronizing signal 31.

Abstract: PURPOSE:To make the state of an actual extension coincident with the state of a lamp corresponding to the extension without increasing the transmission capacity of the signal line by switching the sequential control system and the periodic control system withstanding high traffic in response to the traffic. CONSTITUTION:A lamp control factor detection means 5 detects the production of the necessity of lamp control through the state change of an extension and generates a control request to control a lamp of a display terminal equipment 2. A control changeover means 6 switches a switch 7 with a logic based on a lamp control factor and when a terminal lamp control factor is a low traffic, a 1st lamp control means 3 controls sequentially each lamp and when the control factor shows a high traffic, a 2nd lamp control means 4 controls each lamp simultaneously at a prescribed period. Thus, the control of lighting/extinguishing the lamp is not retarded under a low traffic and the state of the actual extension and the state of the lamp corresponding to the extension are always made coincident to any of the cases at a high traffic and the display terminal equipment having a large number of lamps.
