Title: Transformer winding
Inventor: INOUE TAMOTSU
IPC: H01F27/28
Filed: 1986-03-31
Abstract: PURPOSE:To reduce shared voltage between a continuous disk winding part and an interleaved winding part and realize size reduction as a whole by a method wherein the interleaved winding part is divided into at least two winding parts and wire elements used in the respective windings have different width dimensions. CONSTITUTION:An interleaved wiring part A is divided into a part A1 and a part A2. The relation between the height d1 of the wire element of the winding part A1 which is close to the line end of the winding and the height d2 of the wire element of the winding part A2 is d1>d2 and the cross sectional area of the wire element of the part A1 and the cross sectional area of the wire element of the part A2 are almost the same. Therefore, the relation between the widths l1 and l2 of the respective wire elements is l2>l1. As the relation between the widths of the wire elements of the winding part A1 and the winding part A2 is l2>l1, the relation between the number of turns of the winding part A1 and the number of turns of the winding part A2 is A1>A2. Moreover, as the relation between the heights of the wire elements is d1>d2, the relations between the capacitances of the winding parts A1 and A2 and a continuous disk winding B is A1>A2>B. Therefore, a sudden change of the capacitance does not occur even at the junction C of the continuous disk winding part B and the interleaved winding A so that the shared voltage Ve between the respective windings at the junction C.

Title: Painting method
Inventor: TANIMOTO YOSHIO
IPC: B05D1/02
Filed: 1988-03-25
Abstract: PURPOSE:To obtain a coated film having high smoothness even with a thick film by using such a paint with which a sag is generated only by the heating effect of a baking process and baking the paint while rotating a material to be coated around the horizontal axial line. CONSTITUTION:Spraying of the paint in the painting stage P2 is executed in such a manner that the coated film attains, for example, 100mum thickness above the sag threshold. A powder paint, thermosetting paint adjusted in the content of a sag preventive agent, viscosity, etc., are usable as the paint to be used. The material to be coated after the painting is rapidly transferred to a baking stage P3 and is rotated around the axial center of rotation extending in a horizontal direction. The paint is baked while the material to be coated is kept rotated only during the time when the paint has fluidity in about 150 deg.C temp. atmosphere. The direction and speed of the rotation of the material to be coated are set in such a range where the sag speed of the paint is kept <=2mm per minute which is a permissible range.

Title: Negative resistance bipolar transistor
Inventor: OOTA KUNIKAZU
IPC: H01L29/201
Filed: 1985-04-04
Abstract: PURPOSE:To improve the high frequency characteristics by forming the base with the superlattice which exhibits the negative resistance when high voltage is impressed, and giving the collector the negative resistance. CONSTITUTION:The transistor is constituted of the GaAs semiconductor substrate 1, the N-type GaAs collector 2, the P-type base 3, the barrier layer 4 and the N-type GaAs emitter 5. The P-type base 3 is the superlattice layer formed by alternatively growing the AlxGa1-xAs and the GaAs layers of 50Angstrom  thick, wherein the P-type impurity is doped. The barrier layer 4 is thinly formed with the N-type AlyGa1-yAs of about 20Angstrom  thick. When the high inverse bias voltage is impressed and the depletion layer extends in the base 3, the intense electromagnetic field is produced in the base, and the superlattice base exhibits the negative resistance. Thus the collector resistance shows the negative value.

Title: Optical coupling light receiving element
Inventor: NAKAJIMA TOSHIHIRO
IPC: H01L31/111
Filed: 1985-04-02
Abstract: PURPOSE:To obtain a photo-Triac characterized by a high withstanding voltage, which does not give adverse effects on power loss and power-ON characteristics, without enlarging a chip, by providing irregularities in the P-N junction parts in a current path. CONSTITUTION:Irregularities are provided at least at a part of a plurality of P-N junction parts in an optical coupling light receiving element, which has a current path constituted by a plurality of P-N junctions. For example, an NB layer 1 forms an N-type silicon substrate. The NB layer 1 is oxidized and boron is selectively diffused by photoengraving technology. Thus a PB layer 2 and a PE layer 3 are formed. Phosphorus is selectively diffused from the PB layer 2, and an NE layer 4 is formed. Irregular parts 5-7 are provided at the P-N junction parts of the PB layer 2, the PE layer 3 and the NE layer 4. Thus a broad P-N junction area can be provided by the irregularly shaped P-N junction parts, and injection of electrons and holes in the P-N junction parts becomes easy. Therefore the power loss due to forward voltage drop can be eliminated and the turn-ON time can be shortened. The optical-coupling light receiving element characterized by a high withstanding voltage and high quality can be obtained.

IPC: H01L23/52
Filed: 1989-03-24
Abstract: PURPOSE:To improve the coverage of upper layer wiring and simplify a manufacturing method by forming each dummy wiring layer which has the same wiring width as that of lower layer wiring after making the above dummy wiring layers electrically independent so that lower layer wiring may have the same pitch over the front face. CONSTITUTION:A diffusion layer region 4 consisting of gate polysilicon 3, both source and drain terminals and the like as a MOS transistor is formed on a silicon substrate and contact holes 5 to connect the intervals between respective regions of the transistor are made. Subsequently, aluminum wiring 1 is formed so as to connect mutually transistors and the transistors are electrically connected through the contact holes 5. In such a case, simultaneously dummy aluminum wiring layers 2 are formed. On the occasion of forming lower layer wiring in this way, the formation of the dummy wiring layers 2 having the same wiring width and pitch improves not only the flatness of interlayer films of the upper layers but also that of upper layer wiring. This approach makes the formation condition of the interlayer films constant and makes it possible to form upper layer wiring that is superior in coverage and to simplify a manufacturing method.

Title: Semiconductor device
Inventor: SUZUKI KENSUKE
IPC: H01L21/324
Filed: 1982-05-01
Abstract: PURPOSE:To decrease the increase of leakage currents in the reverse direction, to form the high-speed type semiconductor device of excellent switching characteristics in the forward direction while inhibiting the increase of a voltage drop in the forward direction, to reduce heat loss and to improve reliability by properly setting an area ratio of regions into which gold and platinum are doped as life time killers. CONSTITUTION:When an area of a section A into which gold is diffused increases, reverse leakage currents increase; when an area of a section B into which platinum is diffused increases, reverse leakage currents decrease. Consequently, reverse leakage currents can be inhibited up to set value or less by selecting an area ratio of the sections A, B. The forwared voltage drop is also determined by the area ratio of the sections A, B in the same manner, and brought to the intermediate value of each forward voltage drop in case of the separate doping of gold and platinum. The forward switching characteristics are also determined by the area ratio of the section A and the section B in the same manner, and brought to the intermediate value of the forward switching characteristics in case of the separated doping of gold and platinum. Accordingly, the area ratio of the section A and the section B may be set properly on the basis of characteristics in the diagram in order to conform various characteristics to design value or target value.
