Patent JP-H03102839-A (JP)
Title: Semiconductor device
Inventor: AOKI YOSHIO
IPC: H01L29/41
Filed: 1989-09-18
Abstract: PURPOSE:To prevent crack near the edge of an opening from occurring by providing a large-diameter via hole which is formed to a depth where 20mum to 50mum depth remains from the rear surface of a semiconductor substrate, a small-diameter via hole penetrating to the surface of the semiconductor substrate, a rear-surface side electrode which is formed at the rear surface of the semiconductor substrate, and a surface-side electrode which is electrically coupled to the surface side electrode where one part is exposed to the surface side of the semiconductor substrate. CONSTITUTION:A photo resist film 15 with an opening 15A of the same patterns as that of a large-diameter via hole is formed on the rear surface of a GaAs substrate 11. A large-diameter via hole 12B is formed by performing selective etching of the GaAs substrate 11 with the photo resist film 15 as a mask. It is made as thin as possible to the extent that a thickness which may not produce any crack at the remaining GaAs substrate 11 remains. The thickness of the remaining GaAs substrate 11 where the large-diameter via hole 12B is formed is approximately 20mum to 50mum normally, thus forming a small- diameter via hole 12.

Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a laminar crystalline structure oxide exhibiting a ferroelectric or paraelectric property and a process for producing the laminar crystalline structure oxide capable of easily producing the same. SOLUTION: Raw material prepd. by adding Bi2 O3 as a flux is heated to >=1330 to <=1450 deg.C by a suitable heating up rate (heating stage) and after the raw material is kept at this heating temp. for a prescribed time (constant temp. stage), the raw material is slowly cooled down to >=800 to <=1300 deg.C at a rate of >=1 to <=20 deg.C/hour (slow cooling stage). As a result, the evaporation of the flux is made possible and the direct taking out of Bi2 SrTa2 O9 is made possible. Bi and Sr are partially substituted in this Bi2 SrTa2 O9 and O is selectively made deficient or is disordered. The Bi and O of the fluorite layer are otherwise displaced relatively with each other in the axial direction of polarization.

Title: Method for cooling flange of h-shaped steel having thin web
Inventor: TAMATOSHI TAKANORI
IPC: C21D9/00
Filed: 1992-09-09
Abstract: PURPOSE:To control temperature in the longitudinal direction and in the flange transverse direction of an H-shaped steel having a thin web with high accuracy and to prevent the shape of the H-shaped steel from deforming and the defective quality from being generated by bringing temperature in on-off control at every water cooled zone and/or at every stage in the flange transverse direction. CONSTITUTION:Several nozzles are disposed in a flange width direction in every water cooled zone 1-12 to make a multistage structure. Martensite can be prevented from being generated over the flange transverse direction by bringing a multistage nozzle in this flange transverse direction in on-off control at every stage in each water cooled zone. Further, since each water cooled zone can be used as a recuperative zone by a temporary air cooling in water cooling, the nozzle having a high cooling performance can be used and a cooling line can be reduced.

Title: Facsimile equipment
Inventor: YOSHINO RIICHI
IPC: H04M1/665
Filed: 1991-09-20
Abstract: PURPOSE:To prevent unwanted data from being received in the case of receiving data at the facsimile equipment. CONSTITUTION:When a line is connected in the case of receiving data at the facsimile equipment, the message of 'Plese input the password number' is outputted by a voice transmission part 13. When no password is inputted from the transmission side, a network control part 8 cuts-off the line after the lapse of fixed time. When the password due to tone signals is inputted from the line, a password number recognition part 14 collates it with a password number stored in a password number storage part 12 beforehand, when the password number is matched, the message of 'Plese transmit data' is outputted and the facsimile equipment is turned to a data transfer waiting state. When the password number is not matched, the processing is finished by cutting-off the line similarly to the case of inputting no password number.

Filed: 1984-11-15
Abstract: PURPOSE:To change the frame size easily depending on the format by changing the size of plural images recorded on a hard copy in the main scanning direction. CONSTITUTION:An input image signal is converted into a digital signal by an A/D converter 1 and stored in plural image memories 2. In taking the maximum frame number of a multi-format as 24 frames in total (4 frames in main scanning direction and 6 frames in sub scanning direction) as shown in figure, the storage capacity of the image memory 2 is 4 frames share and then stores image data 11-14. Since the number of revolutions of a rotary polygon mirror 18 is constant, that is, the main scanning speed of a printer is constant, the size in the main scanning direction of a recorded image is changed as a signal RCP changes. In an example of format shown in figure, images I1-I4 are recorded at first and then the next 4 frames are stored succeedingly in the image memory 2 and then I1'-I4' are recorded, 24 frames are recorded by 6 times of repetition in this way.

Title: Recovering device for metallic vapor
Inventor: MIURA HIROHISA
IPC: C22B9/02
Filed: 1983-12-21
Abstract: PURPOSE:To enable recovery of metallic vapor in a molten metal state at a high yield by treating the metallic vapor with a hermetic type cylindrical vessel which has internally deflecting plates, is provided with a step valve communicating with a vacuum pump and has a heater. CONSTITUTION:The vapor of metal such as Mg or the like is supplied from a metallic vapor generator 21 through a pipe 19 and an inlet 18 into a cylindrical vessel 2 closed hermetically with a cap 4 and a bottom plate 14. A stop valve 13 connecting to a vacuum pump 12 is intermittently opened and closed and the Mg vapor is sucked by a vacuum pump 12 so that vortexes are generated by deflecting plates 26. The Mg vapor flows toward the inside wall 9a of a side wall 9 and is quickly cooled to solidify on the inside wall surface 9a. The Mg vapor solidifies in the form of powder on the surface 9a in a lower hermetic space 3 while the valve 13 is held closed. The Mg vapor is thus mostly wholly solidified in the vessel 2 and therefore electricity is conducted to heaters 27, 28 at a suitable timing to melt the solidified Mg. The molten Mg is gathered on a bottom wall 14 and is taken out through an outlet 15 by opening a valve 15.

Abstract: PURPOSE:To improve the electric current efficiency of a gold plating liquid without losing gold by adding a reducing reagent to the gold plating liquid having decreased current density and contg. gold in the form of the cyanide complex salt of an alkaline metal. CONSTITUTION:Gold plating is executed by using the gold plating liquid contg. gold in the form of the cyanide metallic salt of the alkaline metal such as potassium gold cyanide as a supply source for gold and using an insoluble anode, by which the univalent gold cyanide in the gold plating liquid is oxidized and tervalent gold cyanide is formed and the current efficiency is decreased. The reducing reagent consisting of sodium, potassium ammonium salt, etc. of sulfurous acid or pyrosulfurous acid is added to such gold plating having the decreased current efficiency to reduce the tervalent gold cyanide to univalent gold cyanide. The current efficiency is thus improved and the gold plating liquid is restored without the loss of the gold and without giving adverse effect at all to the gold plating.
