Patent JP-S61174768-A (JP)
Title: Semiconductor device
Inventor: KANO ISAO
IPC: H01L29/45
Filed: 1985-01-30
Abstract: PURPOSE:To prevent breakdown of a P-N junction, which is formed in a shallow depth, by making an electrode wiring layer of a metal silicide at a part of an electrode taking out part thinner than the other part. CONSTITUTION:Holes 13 are provided in an SiO2 film 12 as specified, and electrodes and wirings are formed by poly Si. Then, a part of the electrode is coated by SiO2. Pt is deposited on the entire surface, and heat treatment is performed. Pt silicide having a specified thickness is formed on the surface of the poly Si. The non-reacted Pt and the SiO2 mask are removed. The Pt is deposited again on the entire surface so that it is thinner than the first time. Heat treatment is performed. The Pt silicide is formed at the electrode part, which is masked at first. In the metal silicide layer, the resistance of the layer is decreased in inversely proportional to the thickness. The P-N junction of a semiconductor is broken at a certain thickness or more. In this constitution, however, since the metal silicide can be formed in a desired thickness, the breakdown of the P-N junction is prevented, and the device having low layer resistance is obtained at a high yield rate.

Title: Image forming device
Inventor: ISHIGAKI KOJI
IPC: G03G15/00
Filed: 1989-01-27
Abstract: PURPOSE:To improve accuracy in correcting and controlling image forming conditions by varying previous image forming conditions so that an initial output value corresponding to a control pattern for image forming conditions is within a previously set range. CONSTITUTION:Since exposure quantity on the face of a drum 4 greatly changes even in a combination of a constant exposure quantity (a voltage of a lamp 35 is constant) and a white reference pattern 42, a reference value (initial reference data) has to be set by device. Namely, the quantity of reflected light is not constant, and accordingly a potential of the pattern part of the photosensitive drum 4 is not constant. Therefore, since a toner attaching amount (density of a toner image of the pattern) determined by (pattern part potential) (developing bias potential) comes to be not constant, a fresh toner image is formed in response to a pattern of constant density after a developing bias being one image forming condition is increased or decreased in response to an output from the sensor. When the previously set level is obtained by performing these procedures, setting ends. A block diagram indicating these procedures is shown at the right.

IPC: H04M1/58
Filed: 1983-02-03
Abstract: PURPOSE:To improve an anti-side tone characteristic with a simple constitution by connecting an impedance circuit to a balancing network in series and correcting the high frequency impedance component of an insulating transformer by the impedance circuit. CONSTITUTION:One end of a capacitor 10 is connected to one end of a resistor 2 in a T-type bridge circuit, and one end of a receiver circuit 8 is connected to the other end of the capacitor 10.

Filed: 1991-01-18
Abstract: PURPOSE:To obtain the subject reinforcing fiber giving a uniform FRP having excellent water-resistance without lowering the pot-life by applying a cure accelerator for a resin to a reinforcing fiber, thereby promoting the curing of a thermosetting resin. CONSTITUTION:An emulsion of cobalt naphthenate is sprayed as a cure accelerator for a thermosetting resin (preferably unsaturated polyester resin, etc.) to the surface of a reinforcing fiber for FRP such as glass fiber, carbon fiber and organic fiber to uniformly apply the accelerator to the fiber. A liquid thermosetting resin is impregnated into the fiber and cured by heating. The curing time can be shortened by this process.
