Patent JP-H03108656-A (JP)
Title: Mass spectrometry
Inventor: TAKEDA TAKEHIRO
IPC: G01N27/62
Filed: 1989-05-26
Abstract: PURPOSE:To reduce a change in ion detecting limitation to securely detect ions in an entire measurement range by switching over magnetic field intensity according to a mass range of ions to be detected. CONSTITUTION:An exciting current source Sb converts a digital data signal corresponding to magnetic field intensity from a controller C into electric current. An ion accelerating voltage source Sa converts a digital data signal corresponding to ion accelerating voltage from the controller C into voltage. Ion accelerating voltage is to be taken as a constant value per stage, wherein voltage may be varied in a sawtooth state within a micro width with a specific voltage as the center during a time per stage of the ion accelerating voltage and mass scanning may be performed within the micro mass range. Thus a small shift of the ion accelerating voltage and the magnetic field with respect to a peak to be detected while the ion accelerating voltage and magnetic field intensity are to changed in steps can be covered thereby securely detecting ions of a mass to be detected.

Title: High frequency heating device
Inventor: YOSHINO KOJI
IPC: F24C7/08
Filed: 1988-05-31
Abstract: PURPOSE:To detect a heated state of a food by a simple construction and obtain a specified finish of cooking, by installing a steam port different from an exhaust port in a position where it does not face the air of a cooling fan, and mounting a piezoelectric component in such a manner that it may face sand steam port. CONSTITUTION:A part of cooled air in a radio wave ejector 8 is introduced into a heating chamber 6 by way of a duct 10 by driving a cooling fan 9. The air 13 which includes a cooled air 11 and vapor or oil generated from a food, is sent to the outside from the heating chamber 6 passing through an exhaust port 14. A piezoelectric sensor 1 is mounted in a vapor port 15 in order to detect vapor generated from a food as its main service. The position of the vapor port 15 is selected so that it may be exposed to a boiling steam most frequently, avoiding the contact with the air of the cooling fan 9. This construction makes it possible to reduce the effect of the cooling air 11 in the radio wage ejector and obtain an extremely stabilized finish of cooking, since only boiling steam is collided with the piezoelectric sensor, thereby providing an excellent output of S/N ratio.

Title: Semiconductor sensor
Inventor: TAKAHASHI YUKINOBU
IPC: H01L29/78
Filed: 1988-05-31
Abstract: PURPOSE:To achieve a longer life of a photosensitive body or the like, by cutting a DC bias voltage applied to a gate voltage for determining a working point of a MOSFET, by an electrostatic capacitance of an insulation film to keep a DC voltage from reaching a sensitive body. CONSTITUTION:An AC signal outputted from an AC signal generator 12 develops in a first sensitive electrode 9 through a second sensitive electrode 11 and a sensitive body 10. Under such a condition, when an external factor such as moisture as object to be detected is absorbed by the sensitive body 10, a dielectric constant of the sensitive body 10 changes while a change in capacity C2 is caused. As a result, an AC signal appears in the sensitive electrode 9 being varied corresponding to the size of the external factor. This signal causes a change in field intensity for a gate electrode 5 through an insulation film 6 eventually varying current between the drain 2 and the source 3 of a MOSFET. Then, the current change is taken out as change in the drain voltage or source voltage thereby detecting an external factor such as moisture.

Title: Method for decarburizing refining molten chromium-containing steel
Inventor: TAKANO HIRONORI
IPC: C21C7/068
Filed: 1992-05-26
Abstract: PURPOSE:To improve decarburizing rate and to efficiently execute the decarburization by regulating blowing condition of a top-blowing lance in the range having the specific value or higher of the carbon concn. at the time of decarbonizing molten chromiumcontaining steel. CONSTITUTION:In the range of >=0.4% carbon concn. in the molten steel 3, by blowing protecting gas from an outer pipe and oxygen or oxygen and inert gas from an inner pipe in a double tube tuyere 2 below the bath surface, the molten steel 3 is positively stirred to activate fluidity of the bath surface. On the other hand, oxygen or oxygen and an inert gas are blown on the bath surface from the top-blowing lance 1 at high velocity to generate high temp. firing point 5 on the bath surface. Then, blowing velocity of the top-blowing lance 1 is made to be sound velocity or higher of gas spouting velocity from the lance nozzle, and further regulated so that a ratio h/d0 of length (h) in the range where the gas velocity from the lance nozzle becomes the sound velocity or lower, and the min. hole diameter (d0) of the top blowing nozzle becomes 40-80. By this method, the decarburizing efficiency is further improved and the decarburizing refining time is shortened.

Title: Detector for light employing semiconductor
Inventor: HASHIZUME TSUNEO
IPC: H01L27/144
Filed: 1979-10-16
Abstract: PURPOSE:To shorten the diffusion distances of carriers and improve spatial resolving power by a method wherein gold is selectively diffused into a semiconductor substrate. CONSTITUTION:A plurality of P type photosensors 13-15 are formed in such a manner that conductive P type diffusion regions 13-15 opposite to a semiconductor substrate 11 are made up into the substrate 11 containing N type impurities through an oxide film 12. Gold diffusion regions 16, 17 are built up by selectively diffusing gold into the substrate 11 between the sensors 13 and 14 and the sensors 14 and 15. Consequently, when an incident light is irradiated onto one photosensor, carriers are generated in the substrate 11, migrate in the substrate 11 by thermal diffusion, but recombine by the regions 16, 17, and do not reach to separated sensors. Thus, the spatial resolving power of a device is improved because the generation of signal currents due to the carriers collected to the sensors is decreased when the structure with the gold diffusion regions is compared to the conventional structure withno  gold diffusion region.
