Title: Powder for continuous casting
Inventor: HARADA HIROSHI
IPC: B22D11/108
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To stably increase alloy concn. by using powder for continuous casting mixed with ferro-alloy powder at the time of the continuous casting and positively adding alloy element to molten metal in a mold. SOLUTION: The powder used for continuous casting is the one obtd. by adding and mixing the ferro-alloy powder having <=1mm max. grain diameter and adjusted so that the powder of <=10μm grain diameter amounts to <=20wt.% of this powder to the powder for continuous casting without forming sintered layer. The reason of the adjustment of the ferro-alloy powder is that in the case powder size is too small, a time required to pass the mixed alloy powder through the molten powder layer and reach a meniscus, is long and most of the powder is retained in the molten powder layer, and on the contrary, in the case the powder size is too large, such fear as to deteriorate the surface quality of a cast slab due to partially insufficient melting of the powder and uneven flowing into gap between a mold and solidified shell occurs.  Then, the mixing quantity of the alloy powder into the powder depends on alloy concn. in the molten metal, and the upper limit is not specially decided.

Title: Optical record carrier reader
Inventor: HIGUCHI YOSHINORI
IPC: G11B7/126
Filed: 1981-06-02
Abstract: PURPOSE:To obtain a stable semiconductor laser output by shifting the polarization direction of a beam of light from a light source from a polarization direction determined by a polarizing beam splitter, and then using light split by the beam splitter for feedback. CONSTITUTION:The polarization direction of a beam of light from a laser diode  11 is shifted slightly from a polarization direction determined by a polarizing  beam splitter 12, and consequently the beam from the light source is split into a  beam from a record carrier to a signal photodetector 15 and a beam to a feedback photodetector 13. The feedback photodetector 13 transduces the beam into  an electric signal, which is amplified by an amplifier 17 and then compared  with a reference signal 14; and an amplifier 18 amplifies the difference signal,  thus forming a loop for making the quantity of output light of the laser diode 11 constant. Therefore, the beam emitted from the light source 11 is split into the beam to the feedback photodetector 13 and a beam to the signal photodetector 15 by only one polarizing beam splitter 12.

Title: Manufacture of field-effect transistor
Inventor: SASAKI FUMIO
IPC: H01L29/778
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To form a gate electrode and a pad electrode without causing step breakage, by using an insulating film formed after element isolation as a spacer for lift-off during ohmic electrode formation. SOLUTION: An operation layer region is recess-etched through an opening 32 using a resist film 22 as a mask until it reaches a n-type AlGaAs electron supply layer 12-a. At this time, the n-type AlGaAs electron supply layer 12-a acts as a stopper during recess-etching, which enables uniform current control. In this recess-etching process, an opening 32 of the resist film 22 formed at the bottom of a mesa as well is also exposed to etchant. Since a SiN film 100 remains on the entire bottom of the mesa, however, GaAs at the bottom of the mesa will not be etched. Therefore, almost no step is produced between a gate electrode pattern and the bottom of the mesa. This makes it possible to form a gate electrode and a pad electrode without causing step breakage.

A shield machine 40 for branch tunnel construction is laid out directed at the penetration direction in the opening. The shield machine 40 is launched from the main tunnel 10, thereby constructing a tunnel 30 branched from the main tunnel 10.

Abstract: PURPOSE:To improve the recording quality by recording a prescribed mark displaying the position of recording paper in the broadwise direction and detecting the position of the recording paper in the broadwise direction to be carried from the position of the mark so as to automatically correct the recording position of the recording means. CONSTITUTION:A mark 11 is recorded on a prescribed position of recording paper 10 in the broadwise direction by a recording section 4.

IPC: B23K7/06
Filed: 1979-07-04
Abstract: PURPOSE: To omit the end treatment in the next process and make it possible to prevent the fusion loss of a scarfing nozzle by surely guiding the leading end of a slab to the central position of scarfing.  
     CONSTITUTION: A slab 3 is transferred onto the slab advancing rollers 2 of a scarfing line 1. At the time when it passes the 1st leading end detector 5, the leading end of the slab is detected and the 1st length measuring device 13 starts measuring the length of the slab. At the same time, an instruction is given to a line driving part 33 which is turn decelerates the rollers and where the leading end of the slab passes the 2nd leading end detector 9, said part decelerates the rollers further, then the slab stops upon going past a scarfer 4. Here, the rollers are run reverse to move the slab reverse. At this same instant, the measured length value from the start of the length measurement until the stoppage of the slab is subtracted by being synchronized with the reverse travel of the slab and is decided comparatively with the above-mentioned subtracted value in referring to the preset positions of the leading end detector, the measuring device and the scarfing center into consideration, whereby the leading end of the slab is surely guided to the scarfing center.

Title: Heat exchanger
Inventor: ISHIYAMA MASAAKI
IPC: B23K1/00
Filed: 1989-04-05
Abstract: PURPOSE:To surely allow brazing material to flow into gap and to prevent insufficient sticking by arranging notch part having dimension a little larger than diameter of the brazing filler rod parallel to side plates at both shoulder parts of fins joining with the side plates and forming inserting grooves for the brazing filler rod. CONSTITUTION:Combustion gas generated with a burner 9 is passed through a combustion chamber 8 and gaps between fins in a heat exchanger 7 and discharged. Water in a pipe receives heat through the fins and the heat exchange pipe 6 and is discharged as high temp. water. When sticking of the fins to the side plates is insufficient, hole is developed by high temp. combustion gas. For this countermeasure, the positions putting the brazing filler rod for sticking the fin to the side plate are formed by arranging the notching parts parallel to the side plates, therefore even if the brazing filler rod bends, the brazing filler rod is brought into contact with the side plate. By this method, at the time of welding with the brazing filler rod, the brazing material is surely allowed to flow into the gap between the fin and the side plate and insufficient sticking of the gap between the fin and the side plate is not developed.

At the time of output request from the user, after the lapse of fixed time or when the quantity of stored information exceeds fixed quantity, the printing history information stored on the storage medium 5 is passed through the plotting part 3, and the printing part 4 performs the printing processing of that information.  Otherwise, this information is transmitted through the transmission/reception control part 1 to the host computer. The user knows the printing history of the printer from the printed information or the information transmitted to the host computer.
