Title: Semiconductor device and its manufacture
Inventor: OIKAWA SABUROU
IPC: H01L29/41
Filed: 1980-06-04
Abstract: PURPOSE:To form a perfectly protective film and to prevent contamination and deterioration of  withstand voltage of a semiconductor device by a method wherein the top face of convex parts consisted of polycrystalline Si layers having concave and convex faces with gently-sloping circumferences are provided on the surface of a substrate utilizing the difference of etching speed between monocrystalline Si and polycrystalline Si. CONSTITUTION:A P<+> type layer 2 is provided in the N<-> type Si substrate 1, P type layers 3 are  buried therein selectively, an N<-> type layer 41, an N<+> type layer 42 are formed epitaxially in continuation, and concentration and thickness thereof are selected as to obtain the necessitated withstand voltage between gate and cathode. An N<+> type polycrystalline Si layer 43 is accumulated thereon. Selective etching is performed after heat treatment to form a gate electrode lead out part  31, and the form of the main face on the cathode side is regulated as to form the concave and  convex shape. At this time, because of existence of the polycrystalline Si layer 43 and rapid etching speed of polycrystalline Si, the circumferences 7 of the convex parts become as gently-sloping.  When they are coated with SiO2 films 8 and resist masks, because uniform coatings can be  formed, generation of unnecessitated etching and invasion of a harmful impurity can be avoided  at those parts. Accordingly deterioration of withstand voltage between the gate and the cathode  can be prevented.

Title: Suppression system for zero continuation
Inventor: MATSUDA KIICHI
IPC: H03M7/44
Filed: 1985-04-09
Abstract: PURPOSE:To suppress continuous bits of '0' completely without increasing a transmission bit rate and to facilitate the generation of a synchronizing signal on a reception side by replacing some of many continuous '0'-value bits with bits having a constant conversion rule relative to past data and transmitting them. CONSTITUTION:When 16 bits of '0' continue, they are transmitted after being converted so that one bit is '1' without fail. In such a case, when the original signal has a bit of 1 among (n+3) bits and then 16 bits of '0' continuously, the two trailing bits after the 16 continuous bits of '0' of the original signal bit pattern are converted forcibly. The conversion is related to the past data; the 15th bit of the zero continuation is the (n+3)th bit of the past data and the 16th bit is the (n+2)th bit of the past data as shown by a data pattern ii after the conversion. Received data on a reception side has a general data pattern iii; and it is compared with the past data according to the transmission- side conversion rule and only when a coincidence is obtained, bits Y1 and Y2 are reconverted into '0' to reproduce the original data.

IPC: H05K1/18
Filed: 1994-04-13
Abstract: PURPOSE:To improve workability and noise proofing property. CONSTITUTION:This device is provided with a microphone holder 12 made of a metallic conductor connecting to an earth of a printed circuit board 13 with elasticity, and the microphone holder 12 is used to support the surrounding of an ECM (electret condenser microphone) 11 while floating the bottom of the ECM.

Abstract: PURPOSE:To obviate the necessity of the surface treatment of fibrous reinforcement and to simplify manufacturing work, by specifying the knitting conditions of a fiber cloth at the time of alternately piling up metallic foils and fiber cloths and applying pressure forming to the above under high temp. and high pressure. CONSTITUTION:The fiber cloth to be used is a plain weave fabric in which the ratio of the diameter (d) of a fiber 2-1 to the average interfibrous spacing S satisfies 1.8<S/d<5.0 and also the ratio of the thickness 2d of the fiber cloth 2 to the thickness (t) of the metallic foil 1 satisfies 0.4<t/2d<1.5. When the above fiber cloth is used, the necessity of regular arrangement of the above fiber cloth on the metallic foil is obviated and mere piling up and successive application of pressure forming under high temp. and high pressure suffice. Moreover, the necessity of the surface treatment of fibers for controlling the chemical reaction of the matrix of metallic foil with the fibers is obviated as well. Accordingly, a high-strength composite material can be manufactured in high work efficiency.

Title: Method of converting heavy oil to more volatile oil
Inventor: KUBO JUNICHI
IPC: C10G47/34
Filed: 1985-04-11
Abstract: PURPOSE:To convert a heavy oil to a more volatile oil while preventing an increase in pressure loss due to coking in a reaction tower, by treating a heavy oil containing 1.0wt% or more asphaltene oil using a reaction tower of which the inside is partitioned with a divider containing a solid catalyst having a capacity for hydrogenation while circulating the heavy oil in the tower. CONSTITUTION:The inside of a reaction tower 5 is partitioned in the vertical direction with a divider 2 into two portions which are connected to each other at the upper and lower portions of the divider 2. A raw oil, a solvent capable of donating hydrogen and a hydrogen containing gas 3 are introduced into the reaction tower 5 through an introduction pipe 1 provided at the bottom of the reaction tower 5. It is preferred that the hydrogen containing gas 3, heavy oil and solvent capable of donating hydrogen be introduced towards the inside of the divider 2 not to flow into the outside of the divider 2. The introduction by the above method results in circulation of a liquid in the reaction tower 5 in the direction as shown with an arrow. A part of the circulated liquid can pass through the divider 2 from the outside into the inside in the direction as shown with an arrow (dotted line). The divider 2 causes a circulated flow, ensures a necessary liquid velocity and prevents clogging of the inside of the reaction tower 5 with a carbonaceous matter.
