摘要:
A travel speed change apparatus for a farm vehicle in which a first speed change mechanism and a second speed change mechanism coact to change the travelling speed. The first and second speed change mechanisms are operable by manipulating a single hand lever movable in two different directions and not two independent levers. This single lever is adapted to actuate the first and second speed change mechanisms by moving in the same direction.

Load control for engine of vehicle for agricultural work with rotary working implement, for avoiding too much deviation of the working depth while preventing the engine from stopping under heavy overloading. The rotary working implement is automatically raised and lowered in accordance with the results of sensing the engine rotation and of the actual working depth. For prevention of the engine failure, the rotary working implement is unconditionally raised whenever engine rotation below a predetermined value is sensed.

A thin film magnetic head has a lower magnetic pole formed on a substrate; a coil arranged on the lower magnetic pole through an adhesive layer; an upper magnetic pole arranged on the coil; and a gap layer formed between the upper and lower magnetic poles. A method for forming the thin film magnetic head has a process for forming a lower magnetic pole on a first substrate; a process for forming a coil on a second substrate having a recessed portion; a process for polishing the first and/or second substrate such that a face of the lower magnetic pole on the first substrate and a face of the coil on the second substrate come in close contact with each other; a process for adhering the first and second substrates to each other such that the lower magnetic pole and the coil are adjacent to each other; a process for forming a gap layer on the lower magnetic pole; a process for polishing or etching a portion or all of the second substrate; and a process for forming an upper magnetic pole. In this magnetic head and the forming method, high performance can be obtained and cost of the thin film magnetic head can be reduced.
摘要:
A thin film deposition system includes a vacuum or evacuated casing in which there is introduced an active gas or an inert gas or a mixture thereof. A filament emits thermions which impinge upon gas molecules to ionize them into positive ions. The ions bombard a target, from which particles are emitted toward a substrate. The particles emitted from the target are also ionized by the thermions. In the vicinity of a grid, more particles from the target are ionized by thermions which are vertically oscillated and ionized molecules of the gas. The ions are accelerated toward the substrate and bombard the substrate, thereby depositing a thin film thereon. The thin film deposition system may additionally have an evaporation source for supporting an evaporant which emit particles to be deposited on the substrate.

A thin film forming apparatus including a vacuum tank capable of introducing an active gas and/or an inert gas thereinto; a source of evaporable substance disposed in the tank; a counter electrode disposed opposite to the source of evaporable substance in the tank and holding a substrate on which a thin film is to be vapor-deposited; a filament disposed between the source of evaporable substance and the counter electrode for generating thermal electrons; a grid disposed between the filament and the source of evaporable substance, and allowing evaporated substance to pass therethrough; and power source means for putting the grid at a positive potential relative to the counter electrode. Electrons emitted from the filament form a plasma in the vicinity of the grid and ionize evaporable substance from the source of evaporable substance before being absorbed by the grid. The ionized evaporated substance then is accelerated toward the substrate for low-temperature deposition on the substrate. Therefore, even a material having low thermal resistance, such as plastics, can be used as the substrate.

摘要:
A cooling system comprising an evaporation cooling device for evaporating an aqueous solution, a water content providing device for allowing vapor evaporated from impurities-containing water to be absorbed into the aqueous solution, and a circulating device for circulating the aqueous solution between the water content providing device and the evaporation cooling device; and a cooling method characterized by comprising the steps of taking in impurities-containing water, cooling a high-temperature body by evaporating water content in an aqueous solution having a boiling point higher than that of the impurities-containing water, allowing vapor evaporated from the impurities containing water to be absorbed into the aqueous solution concentrated by the cooling step, feeding the aqueous solution diluted in the absorbing step to the cooling step, and discharging the impurities-containing water concentrated in the absorbing step. The aqueous solution circulates between the water content providing device and the aqueous solution desalination device, and no salts move between the aqueous solution and the impurities-containing water, thereby providing a cooling system free from scales.

An optical recording medium includes a substrate, a first protection layer formed on the substrate, a recording layer formed on the first protection layer, a second protection layer formed on the recording layer, and a reflection heat radiating layer formed on the second protection layer. The recording layer is of a phase-change type in which the recording layer is changed from an amorphous state to a crystal state by a temperature raising and cooling process by projecting a laser beam onto the recording layer. The recording layer has an interface portion interfaced with one of the first and second protection layers. The interface portion has a thermal conductivity lower than that of a remaining portion of the recording layer.

An apparatus for forming a thin film has a vacuum container to which an active gas, an inert gas or a mixture thereof is introduced, and a source of evaporation from which a substance is evaporated. A counter electrode is disposed in the vacuum container for holding a substrate for forming a thin film thereon in such a manner as to be opposed to the source of evaporation. A grid is disposed between the source of evaporation and the counter electrode and having openings which allow the evaporated substance to pass therethrough. A filament for thermionic emission is disposed between the grid and the source of evaporation. A target is also disposed between the filament and the source of evaporation for emitting sputtered particles. A power source device establishes predetermined electric potential relationships between the grid, the filament, and the target.
