Title: Image forming device
Inventor: HAYASHI MASAYUKI
IPC: H04N1/387
Filed: 1988-02-29
Abstract: PURPOSE:To accurately set an image forming position by deciding the driving timing of a transfer paper carrying device after it is decided whether the driving of a scanner is to be made before or after the generation of a scanner starting signal. CONSTITUTION:In order to form the image at the previously set position of transfer paper 37, it is necessary to align the transfer paper 37 on a photosensitive drum 5. The alignment of the transfer paper 37 is performed by turning on resist rollers 29 by considering a delay time after auxiliary scan effective period signal becomes 'H'. However, when the image is to be shifted to the rear section of the transfer paper 37, namely, when l3<0 (where l3 is the moving distance of the image against the transfer paper 37 in the auxiliary scanning direction), a scanner start signal is outputted a prescribed time after the rollers 29 are turned on when the time until the rollers 29 are turned on from the generation of the scanner start signal becomes negative by calculation. Therefore, the carrying timing of the transfer paper 37 can be set certainly when the picture is formed on the transfer paper 37 by moving the image to an optional place.

Title: Controller for echo canceller
Inventor: OKUDA KOZO
IPC: G10L21/0208
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To suppress decrease in the learning precision of an echo path, even when a noise component of the input signal of an echo canceller is large without making a threshold large by controlling the learning of the echo canceled and its stop, when reference input signal power is larger than a prescribed value, when a receive signal contains a sound and is less than the threshold, and when the receive signal contains no sound. SOLUTION: After various flags, data, etc., stored in a RAM are initialized, a control part 32 decides the level of the reference input signal power and a sound detector 31 decides whether or not the receive signal contains sound. Furthermore, the control part 32 decides whether or not learning can be performed, according to the decision result of the referenced input reference power and the sound/silence decision result of the receive signal. When it is decided that the learning can be performed, a line-side echo canceller 30 learns an echo path, when it is decided that it is disable state, the line-side echo canceller 30 stops the learning of the echo path.

Title: Photographic base
Inventor: UEHARA HIROSHI
IPC: G03C1/775
Filed: 1989-02-27
Abstract: PURPOSE:To provide the base which has the windability and traveling property at the time of emulsion coating and is further suitable for high-speed coatability of the emulsion without generating the clouding in the gloss of the emulsion surface by forming the resin coating surface on the side opposite to the side to be provided with a photographic emulsion layer to the average center line roughness (Ra) ranging 1.1 to 2.2mum. CONSTITUTION:The roughness on the surface (rear surface) on the side opposite to the surface to be coated with a silver halide emulsion is within the 1.1 to 2.2mum range of the average center line roughness (Ra). The slipperiness to the surface of the emulsion layer is degraded and the telescoping at the time of winding and wrinkling at the time of traveling arises if the average center line roughness (Ra) of the roughness of the rear surface is below 1.1mum. The phenomenon of the clouding of the gloss to exert adverse influence on the gloss of photographic paper is liable to arise at the time when the paper is wound while facing the emulsion layer if the average center line roughness (Ra) exceeds 2.2mum. The telescoping at the time of winding, the meandering at the time of traveling and the clouding of the gloss of the emulsion surface are prevented in this way without impairing the function as the photographic base. This base is suitable for high-speed coating of the silver halide photographic emulsion.

Abstract: PURPOSE:To prevent adverse effect onto other circuits by connecting a resistor in series with a ceramic oscillator so as to suppress the odd number order vibration and spurious vibration. CONSTITUTION:A resistor 51 is connected in series between one end E of the ceramic oscillator 14 and a connecting point B between a resistor 13 and a capacitor 16. Through the constitution above, an impedance RS2 of a series circuit comprising the ceramic oscillator 14 and the resistor 51 is higher than an impedance RS1 comprising only the conventional ceramic oscillator 14. Thus, the oscillation circuit is oscillated at the basic oscillation only by setting the resistance value of the resistor 51 to a prescribed value. That is, the relation between the mechanical quality coefficient Qm(R) of the ceramic oscillator 14 and the mechanical quality of a conventional oscillator Qm is expressed as Qm>Qm(R) by providing the resistor 51 in series with the ceramic oscillator 14 and the oscillation circuit is hardly oscillated at frequencies 22, 23 shown in Fig. by providing the resistor 51.

Abstract: PURPOSE:To prevent Si in a diffusion layer from being etched and realize uniform diffusion by a method wherein a thin oxide film is formed on an exposed surface of a semiconductor substrate by dipping the substrate in a highly oxidative solution. CONSTITUTION:A diffusion protection film 12 is formed on the surface of a semiconductor substrate 11 and an aperture 13 is formed in the film 12 to expose the surface of the substrate 11 selectively. Then the substrate 11 is dipped in an oxidative solution to form a thin oxide film 13 on the exposed surface of the substrate 11.

After the substrate 11 is heated sufficiently and uniformly, BCl3 gas and O2 gas are introduced into the reaction furnace to form a boron diffusion layer 15 on the substrate surface under the film 14. With this constitution, Si in the layer 15 is prevented from being etched and uniform diffusion can be realized.
