Patent JP-H0276235-A (JP)
Title: Manufacture of vertical field-effect transistor
Inventor: SAKAI SHINOBU
IPC: H01L21/265
Filed: 1988-09-12
Abstract: PURPOSE:To simplify a manufacturing process and achieve low cost by a method wherein a groove and a first to third impurity area are in turn formed and all of these are formed self-alignedly. CONSTITUTION:After an oxide film 12 is grown as an insulation film on a substrate 11, an opening 13 is formed on the oxide film 12. Next, using the oxide film 12 as a mask, anisotropic etching is performed on the substrate 11, forming a V-shaped groove 14. After a first impurity area 15 is formed, the oxide film 12 is entirely removed. Next, after a gate oxide film 16 is grown on the substrate 11 surface, a gate electrode is selectively formed on the substrate and a second insulation film 19 is formed on the gate electrode and the substrate. With this gate electrode as a mask, the substrate and a second impurity area of an opposite conductivity type are formed and with the second insulation film 19 on the groove and the gate electrode as a mask, the source area of a third impurity area 21 having the same conductivity type as the substrate are formed on both side of the groove in the second impurity area. This makes it possible to form an impurity area self-alignedly and to simplify a manufacturing process.

Title: Multi-element ink jet printer
Inventor: NISHIKAWA MASAHARU
IPC: B41J2/06
Filed: 1985-10-15
Abstract: PURPOSE:To obtain a recording head of high dot density capable of printing at high speed without generating clogging of ink, by a method wherein a counter electrode is disposed on the side opposite to the side having signal applied electrodes of the recording head with spaced away from each other and a recording signal voltage is selectively applied therebetween. CONSTITUTION:In a multi-element type electrostatic ink jet printer using a semiconductive liquid ink, the pulse voltage applied between a counter electrode 5 and a one selected among recording electrodes 4a-4n generates the inrush of charges from the recording electrode to ink columns 8a formed in small openings 3a-3n. The ink columns 8a are charged by the injected charges, simultaneously being so formed as to completely fill the small openings 3 due to Coulomb's force acting against the counter electrode 5. After the time is further elasped, the ink columns 8a are raised from the small openings 3 to be in projection form, and thereafter the ink starts flying.

Title: Photographing lens holding method
Inventor: MORIYA MITSUHIRO
IPC: G03C3/00
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To prevent movement of a photographing lens, even. if a front cover is thermally deformed, by allowing the inner wall surface of an armoring member for covering the front surface of a lens-barrel to abut on the front surface circumferential part of the photographing lens, and by pinching the photographing lens between a support part and the armoring member. SOLUTION: Three presser projections 37a-37c which are projecting parts for holding the front surface of a photographing lens 12 are formed at even intervals around a lens opening. The presser projections 37a-37c are interfitted with a groove 12c of the photographing lens 12, when a front cover 24 is placed on a body base part, to prevent movement of the photographing lens 12 on the surface vertical to the optical axis direction. When the photographing lens 12 is placed, the photographing lens 12 is fixed by being pinched between the presser projections 37a-37c and a support part 36.  The presser projections 37a-37c get into the inside of the photographing lens 12, therefore, if the front cover 24 is thermally deformed and capability for pressing the photographing lens 12 is reduced, the photographing lens 12 is prevented from being moved on the surface vertical to the optical axis direction by engaging between the presser projections 37a-37c and the groove 12c.

Title: Mobile communication equipment with notice means control function and notice means control method for mobile communication equipment
Inventor: TAKAKURA MINORU
IPC: H04W88/02
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a mobile communication equipment with a notice means control function in which a called party easily senses a notice tone independently of a surrounding noise sound volume. SOLUTION: An oscillation section 2 receiving a notice control signal from a notice control section 1 sends a voice signal to an amplifier section 5 via an amplifier section 3. The amplifier section 5 receives an input from a microphone 4 and its output is sent to an averaging processing section 7 via a detection section 6. The voice signal given to the amplifier section 3 from the oscillation section 2 is amplified in the amplifier section 3 depending on the input from the averaging processing section 7 and the voice signal is sounded from a speaker 8. Thus, it is prevented that the called party takes notice with a delay because of a too small notice sound volume or the surrounding persons are troubled because the notice tone volume is too high.
