Title: Semiconductor integrated circuit device
Inventor: OTSUKA FUMIO
IPC: H01L29/78
Filed: 1986-09-26
Abstract: PURPOSE:To improve breakdown strength of a junction between regions of source and drain effectively by having a structure where the regions of source and drain are not in contact with a semiconductor region. CONSTITUTION:An insulating film 3 like phospho-silicate glass film is formed on the field insulating film 2 formed at the surface of a substrate 1 and an n-type buried channel region 5 is formed after implanting n-type impurities through opening 3a where a mask is etched with a photoresist. After reducing the photoresist 4, the insulating film formed at the whole surface is vertically etched with characteristic anisotropy in a perpendicular direction and side walls 6 of insulating materials are formed at the inside. Using the above insulating film as the mask, p-type impurities are implanted and a p<+>type semiconductor region 7 is formed below the buried layer 5 in such a manner of self adjustment. Subsequently, a gate insulating film 8 is formed at the surface of the substrate 1 and after annealing, phosphorus in the insulating film 3 is diffused in the substrate 1 to form n<+> type regions of source and drain 9 and 10. Since these regions are not in contact with the semiconductor region 7, this approach improves a junction breakdown strength.

Title: Method for continuously casting molten metal
Inventor: FUJI TAKEHIKO
IPC: B22D11/04
Filed: 1994-09-21
Abstract: PURPOSE: To obtain a continuous casting method for producing a cast slab having good surface characteristic in many kinds of metals by impressing AC current applied with stepped intensities to an electromagnetic coil arranged to the same axis with a mold around the mold. CONSTITUTION: While induction-heating molten metal 8 in a water-cooling vessel 2 formed with electrically conductive segments by an induction-heating coil 3, this molten metal is held to the molten-state. Thereafter, this molten metal 8 is solidified by using the mold 4 connected with the lower side of the water- cooling vessel 2 and the obtd. cast slab is continuously drawn out. At this time, the electromagnetic force is given to the molten metal 8 in the mold 4 by an intermittent electromagnetic force impressing coil 5 arranged so as to surround the outer periphery of the mold and the lubrication is improved by reducing the friction resistance between a solidified shell 7 and the mold 4. Then, in the AC current impressed to the intermittent electromagnetic force impressing coil 5 on the outer periphery of the mold, the stepped intensities are periodically given in this amplitude.

Title: Subscriber circuit
Inventor: KIKUI HIDEKI
IPC: H04M3/02
Filed: 1986-09-25
Abstract: PURPOSE:To easily integrate a subscriber circuit by detecting whether or not a subscriber terminal answers according to the output signal of a holding circuit which holds the detection result of a comparator when the potential of a call signal is zero. CONSTITUTION:A signal source 5 outputs a rectangular wave whose potential becomes positive, zero, negative, and zero periodically in order. While the potential of the call signal from the signal source 5 is zero, the output of a comparator 7 becomes 1 when a DC power source 6 sends out a DC current to a subscriber line 4, namely, when the subscriber terminal 3 answers to the call signal. Therefore, whether the subscriber terminal 3 answers or not is detected on the basis of the output of a flip-flop 83 which sets the output signal of the comparator 7 at the rise of the output signal of a delay circuit 82. Consequently, a low-pass filter which requires a large-capacity capacitor need not be provided, so the subscriber circuit is easily integrated.

Title: Package for integrated circuit
Inventor: SUGAWARA YASUYOSHI
IPC: H01L23/04
Filed: 1986-09-24
Abstract: PURPOSE:To improve heat sink characteristic of a package for an integrated circuit by providing many protrusions on the surface of a metal cap. CONSTITUTION:Many spherical protrusions 1 each having a radius R and a height H are formed on the surface of a metal cap. In such protrusions, the ratio As/Ab of the surface area As to the bottom area Ab becomes maximum 2 when the radius R is equal to the height H in a semisphere, and is reduced as the height H from the semisphere is lowered. Accordingly, to raise the heat sink effect, it may be formed of a semisphere having the height equal to the radius of the bottom circle. However, if the radius is excessively large, the thickness of the cap becomes thick. Therefore, the heat sink efficiency can be improved without increasing the thickness by reducing the radius of one sphere.
