Title: Ic circuit
Inventor: KITANI KAZUNARI
IPC: G01R31/3185
Filed: 1994-10-06
Abstract: PURPOSE: To reduce the number of action changing input pins in an IC circuit by changing a test mode and a normal action mode between each other by an action changing circuit in accordance with an input voltage inputted to an input pin. CONSTITUTION: In the case of conducting a test mode on the IC maker side, when a similar voltage to a power supply voltage E is applied to an input pin 6, outputs of comparators 9, 10 get to at a high level, and an output of an AND circuit A1 is at a high level, so a test mode signal TEST is outputted. When this signal TEST is generated, an action changing circuit 4 changes an IC1 to an IC test mode, and executes the IC test mode. Next, in the case of conducting a normal action mode on the user side, as a voltage about half the power supply voltage E or similar to the grounding voltage is applied to the input pin 6, the action changing circuit 4 changes the IC1 to the normal action mode. A CPU 2 is resetted and released, and a main program memorized in a mask ROM in the CPU2 is then executed.

Title: Information recording medium
Inventor: KOBAYASHI TADASHI
IPC: G11B7/243
Filed: 1988-09-30
Abstract: PURPOSE:To perform a high-sensitive information recording with a light beam of a smaller power by using a material having a melting point below a predetermined temperature for a recording layer. CONSTITUTION:A recording layer having fine irregularities on its surface is irradiated with a light beam, whereby the part irradiated with the light beam is smoothened, and information is recorded. A material having a melting point of 900 deg.C or less is used for the recording layer. As a practical material for forming the recording layer, a film made of at least one of Te, Sb, Bi, Se, Al, In, Zn, Mg, Pb, and Sn or a thermoplastic organic film is used. On the surface of this film, projections or recesses smaller than a light beam condensing spot are formed. In the recording of information, the surface of the recording layer is melted by the irradiation of a light beam to be smoothened and, thereafter, solidified. Since the reflectance and other optical characteristics of a part having irregularities are different from those of the smoothened part, the difference between these optical characteristics is detected, and the regeneration of information is performed.

Abstract: PURPOSE:To detect the short break of a power supply positively by connecting a rectifier circuit having a rush-current preventing circuit, and a rectifier circuit, which does not have the preventing circuit thereof, in parallel, comparing the terminal voltages of smoothing capacitors of both rectifier circuits and controlling the rush- current preventing circuit. CONSTITUTION:A first rectifier circuit 1 rectifies the AC of a power supply input part 20 with a rectifier element 11. A DC is supplied into a load circuit 5 through an inrush-current preventing circuit 10 comprising a current limiting resistor 14 and a switch 13 and a first smoothing capacitor 12. A second rectifying circuit 2 in parallel with the first rectifying circuit 1 rectifies the AC of the power supply input part 20 with a rectifier element 15. The output is smoothed with a second capacitor 16. The DC is supplied into a load 6. The capacitance of the capacitor 12 is set at the value larger than the capacitance of the capacitor 16. When service interruption or short break occurs, power is supplied from the capacitors 12 and 16 into the load circuit 5 and 6 during this period, and the output voltages are gradually lowered. When the difference exceeds the specified value, a voltage comparing circuit 4 outputs the result of comparison, and the switch 13 is opened through a control circuit 3. Thus, the short break is positively detected, and the inrush current is suppressed.

Title: Sheet molding method
Inventor: YAGI TAKUJI
IPC: B29C48/305
Filed: 1987-09-29
Abstract: PURPOSE:To eliminate deposits of blended materials containing a large quantity of fiber-like reinforcing material or an inorganic compound at the outside of an edge and carrying out a continuous operation of high quality in a stabilized manner by making an angle of the edge end of a T-die outlet section a given angle or less through a polymer flow passage. CONSTITUTION:The angle of an edge end of a T-die outlet section is lessened to 30 deg. or less through a polymer passage in the method of melt extruding a material consisting of thermoplastic resin of ultimate viscosity of 0.6 or more blended with at least one of fiber-like reinforcing material and an inorganic compound out of a T-die, cooling the same by cooking rollers and sheet molding. In case of a low viscosity material less than 0.6 viscosity, a neck-in between the T-die and the cooling rollers gets large to make the sheet molding difficult, and in an extreme case, a thermoplastic resin polymer only is fluidized and extruded to deposit the fiber-like reinforcing material and the inorganic compound on a wall surface in the T-die. The adhesion of the fiber reinforcing material or the inorganic compound is not generated by lessening the angle of the edge end to 30 deg. or less through the polymer flow passage, but it is not necessary to lessen the angle to 10 deg. or less from the viewpoints of retaining the strength at the end and also the processing cost.

Abstract: PURPOSE:To improve the adhesive property of a diamond film on a substrate consisting of a sintered hard metal for cutting tools, etc., by electrolytically polishing the metallic substrate in a mineral acid, then flawing the base body with abrasive grains and forming the diamond film at the time of coating the surface of the metallic substrate with the diamond film by a vapor reaction. CONSTITUTION:The surface of the metallic substrate for cutting tools obtd. by sintering the high hardness particles of the carbide, nitride, boride, silicide, etc., of metals with iron family metals, such as Co, Ni and Fe, as a binder is used as an anode and is subjected to electrolytic polishing as a pretreatment in the mineral acid, such as hydrochloric acid, sulfuric acid, and nitric acid, by which numerous projections are formed on the surface. The abrasive grains of diamond, cubic boron nitride, alumina, etc., are then blown onto the surface to flaw the surface. This metallic substrate 4 is put into a reaction furnace 1 and is placed in a region 7 where the gaseous acetylene from a nozzle 2 of a burner 6 is incompletely burned. The diamond film having the high adhesive strength is thus formed on the surface of the metallic substrate 4.

IPC: C21C7/10
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To extend the service life of an immersion tube by improving the cooling of a core metal forming the immersion tube in a degassing equipment. SOLUTION: Cooling water is supplied into a water supplying tube 14 by driving awater supplying pump 19, and after promoting the cooling of double tube core metals 13 and a refractory 3 by flowing the cooling water into a cooling water piping 17 arranged in the gap of the double tube core metals 13, the cooling water is drained from a drainage pipe 10. Since the cooling water is used as the cooling medium, the cooling capacity can drastically be increased. Further, since the cooling of the double tube core metals 13 is executed by supplying the cooling gas into the gap of the double tube core metals 13 from a cooling gas supplying tube, the extension of the service life of the immersion tube 10 is achieved.  In the case the cooling water piping 17 breaks from happening, the steam developed caused by water breakage is quickly escaped to the outer part through a gas exhaust opening hole 16 to prevent the steam explosion. Further, the steam in the cooling water piping 17 is escaped to the outer part through a safety valve 21 arranged in each of the water supplying pipe 14 and the drainage pipe 15.
