Title: Image forming device
Inventor: KOJIMA KISHO
IPC: G03G15/16
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a streaky retransfer by providing a retransfer preventing member for applying a voltage having the same polarity as that of the charge of the toner of a toner image, so as to prevent a retransfer, that is, the retransfer to an image carrier, of the toner image after being once transferred to a transfer material. SOLUTION: In a wedge-shaped space formed between the transfer material B on the downstream side in the moving direction of the surface of the image carrier 16 adjacent to a transferring position Q3 and the image carrier 16, the retransfer preventing member Rt is arranged. An applied voltage means 32 applies the voltage having the same polarity as that of the charge of the toner of the toner image, to the retransfer preventing member Rt. This member Rt prevents the generation of the retransfer in the wedge-shaped space formed between the transfer material B on the downstream side of the transferring position Q3 and the image carrier 16. Thus, the retransfer does not occur so that a streaky void is not generated in the toner image after being transferred to the transfer material B.

Title: Automatic gain control circuit
Inventor: TOGASHI SHIGEKAZU
IPC: H03G3/30
Filed: 1986-09-16
Abstract: PURPOSE:To obtain a stable automatic gain control circuit against noise without adding a reference signal for automatic gain control by deciding the amplification factor of the gain control means by an error detection means output signal and a component detection signal. CONSTITUTION:A reception signal is divided into three in terms of frequencies at crossover frequencies fc1, fc2 of low frequency replacement devices 2, 4. An error signal detected by an error detector 5 is an error as to the component between the frequencies fc1 and fc2. On the other hand, a component detector 6 detects the component between the frequencies fc1 and fc2 of the digital signals after identification. While it is detected by the detector 6 that an intermediate frequency component of a prescribed level or over is included in the reception signal, the amplification factor of the output signal of the error detector 5 to the input reception signal of a gain controller 1 is controlled. When it is detected by the detector 6 that the intermediate component included in the reception signal is a prescribed level or below, the amplification factor of the gain controller just before to the input reception signal is stored.

IPC: H01L21/768
Filed: 1994-09-12
Abstract: PURPOSE: To provide a method for manufacturing a semiconductor device wherein the progression of etching of a layer which protects electrodes is prevented when a contact hole is formed by the self-alignment method and thereby an yield and the reliability of a semiconductor device are increased. CONSTITUTION: An oxide film 107 is formed for insulation of the entire surface. On the oxide film 107, an etching stopper film 108 which is constituted of a silicon nitride film is formed to protect the layers formed under the oxide film 107 from etching. Furthermore, a polycrystalline silicone film 90 is formed on the etching stopper film 108. The existence of the polycrystalline silicone film 90 prevents the etching stopper layer from being removed and interconnect layers from being exposed. Therefore, the shorts between the interconnect layers can be prevented, resulting in the increase in an yield and the reliability of a semiconductor device.

Title: Nonlinear optical element for higher harmonics generator
Inventor: NAKAMURA KAZUNORI
IPC: G02F1/37
Filed: 1986-09-16
Abstract: PURPOSE:To obtain an optical element with a high optical intensity and to make light into a long wave or a short wave easily and highly efficiently by sequentially forming outer layers with materials with sequentially lower refraction factors with respect to a center core. CONSTITUTION:The center core 10 is made of the materials with light perviousness with respect both to input light and a higher harmonic, and its outer layer 10 is formed with the material which easily generates a higher harmonic and has a lower refraction factor than that of the core 10. An layer 30 outer than the layer 20 is formed with the material with light perviousness with respect to input light and a lower refraction factor than that of the layer 20. An input wave 24 is generated in the layer 20 in the direction where the higher harmonic 25 advances, fully reflected on the boundary between the layers 20 and 30, and advances in a fiber. The higher harmonic 25 is trapped in the center layer, and propagated in a specific mode. If time required for the light to advance in a length of (2m+1)Xlambda/2 coincides with time required for the input wave 24 to advance in a turning point to the layer 10 from the layer 20, the higher harmonic 25 to propagate the core 10 is amplified in the longitudinal direction of the fiber. Then the core 10 develops the intensity of a higher harmonic, and a thin beam is outputted.

Title: Acceleration detector
Inventor: KAJI HIROYUKI
IPC: G01P15/02
Filed: 1986-09-18
Abstract: PURPOSE:To measure acceleration with an extremely small variation with time by utilizing the piezoelectric resistance effect pressure sensor of a silicon single crystal. CONSTITUTION:When a mass body 2 is moved by applying the force to a detector as shown by an arrow, the mass body 2 slides on the inner peripheral wall 1c of a hollow part 1b by a seal member 3, so it is to stop at a reference position by inertia. Namely, a hollow cylinder 1 and the mass body 2 move relatively to each other and this movement is transmitted as pressure to the pressure sensor 4 through noncompressed liquid 5. A rise in the pressure in the hollow part 1b, on the other hand, exerts no influence upon an atmospheric pressure open side through an air vent 6a by a sealing member 3. Thus, an electric signal output proportional to the pressure is obtained by the pressure sensor 4. Consequently, when variation with time is small, the output appears as a DC signal and the frequency characteristics of the detector extend completely to a DC range, so that acceleration is measured with extremely small variation with time.
