Abstract: PURPOSE:To form a base layer to be shallow and to reduce an irregularity in a resistance value of a polysilicon layer for resistance use by a method wherein silicon ions are implanted into an epitaxial growth layer in a base region and into the polysilicon layer for resistance use in an interelement isolation region. CONSTITUTION:A polysilicon layer 8 for resistance use and the like are formed on a silicon substrate 1; after that, the polysilicon layer 8 for resistance use is removed selectively by an anisotropic etching operation using a Freon-based gas. Then, a resist film 9 is formed; silicon ions Si<+> are implanted selectively, by using this film as a mask, into an epitaxial growth layer 3 in a base region and into the polysilicon layer 8, for resistance use, which has been left in an interelement isolation region; these layers are made amorphous; after that, boron ions B<+> or boron fluoride ions BF2<+> as impurities are implanted selectively into parts into which the silicon ions Si<+> have been implanted. During this process, since the parts into which the silicon ions Si<+> have been implanted are made amorphous; it is possible to prevent them from being channeled; a depth of a base layer 10 formed by implantation of the impurities can be made shallow.

Title: Polymerizable mixture containing (meth)acrylate, preparation of (meth)acrylic resin, method for reducing yellowing, resin and composite glass containing the resin
Inventor: KURAUSUUUUBUE KOTSUHO
IPC: C08F20/10
Filed: 1993-01-08
Abstract: 2.1. Poly(meth)acrylates which contain silanes as adhesion promoters (coupling agents) for bonding to, for example, silicate glass tend to yellow. The yellowing can be reduced by addition of UV absorbers or covered by appropriately coloured glass sheets, but this means that the corresponding systems can no longer be initiated by UV. In addition, such systems do not always have a sufficiently long shelf life. The novel silane-containing methacrylate resin composition therefore contains components which have a reduced tendency towards yellowing. 2.2. The novel composition contains 20-99.9% by weight of (meth)acrylic esters ((meth)acrylates), optionally further comonomers or polymers and plasticizers and 0.1-30% by weight of a silane. 100 parts by weight of this mixture are reacted with free-radical formers, Cu<2+> and a quaternary amine. The components can be stored and reacted in premixtures. 2.3. Preparation of laminated glass sheets.

The straight tube type bulb 1 is curved and worked annularly by rotating and moving a curved drum 10 along the straight tube type bulb 1. The inert gas 9 in a ring type bulb 1' is exhausted and inert gas 9' such as argon and krypton and mercury, etc. are supplied.

Abstract: PURPOSE:To prevent a filter from being damaged by melting and to reduce power loss, by operating a pump for supplying secondary air to upstream of a particle gathering filter only when an engine rotates at a low speed with a small load. CONSTITUTION:A turbocharger 3 has an exhaust pipe 6 connected to down stream of its exhaust turbine 4, the exhaust pipe 6 being provided with a filter receptacle including a particle gathering filter 8 and an igniting electric heater 9. An ejecting nozzle 19 for ejecting secondary air to the electric heater 9 is disposed upstream of the heater 9 and the ejecting nozzle 19 is connected with the outlet of a secondary air supply pump 21 through a passage 20.

Title: Balance control circuit
Inventor: TAGOME REIJI
IPC: H03G3/02
Filed: 1995-01-10
Abstract: PURPOSE: To expand an input dynamic range by providing two channels for balance control independently and supplying a control current for the case between minimum balance and center balance and for the case between center balance and maximum balance. CONSTITUTION: A balance control current based on a balance center as a reference flows into an input terminal 1 or flows from the input terminal 1. A converter 16 classifies the control current into two for the case between minimum balance and center balance and for the case between center balance and maximum balance and provides an output of a control voltage proportional to the control current in response to the absolute control current value to a Rch balance control section 14 and an Lch balance control section 15. Both volume and balance adjustment sections Rch11, Lch12 receive an output voltage from the control sections 14, 15 and provide a maximum voice output at balance center and reduce a voice output in response to the balance control voltage. Thus, the capacity for balance control DAC output current smoothing is reduced and a large dynamic range is obtained.
