Abstract: The invention provides an analog input and output circuit and a vacuum processing apparatus capable of automatically performing the correction of all analog inputs and outputs via a single reference voltage adjustment, thereby solving the prior art problem of requiring a different correction value for each channel for accurately controlling the analog input and output due to the difference in the on resistances of switches for respective channels of an analog multiplexer.

Abstract: A rotation angle detector has a rotary member which is rotated in association with a steering shaft, detecting members each of which is rotated in association with the rotary member, magnets which are arranged in correspondence to these detecting members and rotated integrally with these corresponding detecting members, magnetic sensing devices which are arranged opposed to the respective corresponding magnets, and a controlling circuit for calculating a rotation angle of the steering shaft based on detection signals from the magnetic sensing devices, wherein at least one of the magnets has a first section on a side of the magnetic sensing device, and a second section on a side opposite to the magnetic sensing device, and the north pole and the south pole of the first section are arranged in a reversed manner to those of the second section.

Abstract: The present invention relates to a thermal line printer for a small recording terminals such as a terminal for POS (point of sales), a handy terminal, a measuring apparatus or the like, and also relates to a driving device for the thermal line printer. In the structure of a conventional thermal line printer, there is a limitation to the ability to decrease the dimension of depth in a situation where the downsizing of an apparatus is desired. By installing the thermal line printer in an upright state, the dimension of the depth can be decreased. However, in this configuration, the user cannot see the state of the printing because the recording paper falls down toward the user's side, due to the gravity, when the paper is ejected after printing.

Abstract: A method of producing an exhaust valve for a diesel engine comprising the steps of cutting a part of a valve or valve seat body, depositing or spraying onto the cut part a mixture of grains of ceramics and metals, and varying the proportion of grains of ceramics and metals during the deposition or spraying so that the deposited or sprayed layer will vary in content of metal and ceramics with the proportion of ceramics increasing with the increase in height from the valve or seat body of the coated layer, and then subjecting the coating to pressure of 3 to 7 Kg/mm.sup.2 and concurrently heating the coating to 700.degree. to 800.degree. C., thereby to produce a contact surface which forms the contact point between the valve and valve seat which has better adhesion, is close to the body, and has better corrosion resistance, anti-invasion properties, and good thermal shock resistance.

Abstract: This invention is concerned with an exhaust valve for Diesel engine and a method thereof, in which a seat of the exhaust valve is formed with coated layer comprising ceramics and metals, the layer becoming thicker in density of ceramics as coming nearly to the surface thereof. The seat may be formed with the coated layer by subjecting to pressing-heating treatment after coating. This kind of the exhaust valve is provided by coating ceramics and metals onto a seating portion of the mother material such that ceramics becomes thicker in density as advancing to the surface, and heating the coated layer in electric conductivity while pressing the layer with the tool in non oxidizing atmosphere.
