IPC: G03F3/08
Filed: 1983-07-04
Abstract: PURPOSE:To discriminate easily a hue signal from a density signal by converting a negative original density signal read by photoelectric-scanning on a negative original into a density signal corresponding to a positive image so that the ratio of the weight of the three primary colors of the density signal corresponding to the positive image is made constant at all times and identical. CONSTITUTION:After the input signal obtained by photoelectric-scanning the negative original loaded to an input drum 1 is converted into the density signal by a logarithm converting circuit 2, the result is inputted to an input signal processing section 4 via an AD converter 3, where the signal is converted into a positive original density signal being the equivalent neutral density in which the ratio of the weight of the B, G, R signals is constant and identical, and then the result is inputted to a color processing section 5 to be called the heart of the system, where the signal is processed by color processing, gradation processing and sharpness processing. Thus, the density signal outputted from a color processing section 5 is inputted to a modulator 8 via an output signal processing section 6 and further a DA converter 7 so as to modulate laser light outputted from a light source 9, thereby reproducing a desired picture on an output drum 10.

Filed: 1983-07-06
Abstract: PURPOSE:To enhance the flow-rate controllability to a great extent, by disposing a slider such that the slider comes to a completely closed position at the rotational position of an armature at which current is supplied only to a valve closing coil for the armature. CONSTITUTION:An idling-speed control valve controls the engine speed at the time of idling operation by controlling the quantity of intake air passed through a by-pass passage. In respect of the relative angular position of a slider 4 and an armature 10, the slider 4 is fixed to a hollow shaft such that the slider 4 comes to a completely closed position at the rotational position of the armature 10 corresponding to the duty ratio 0% when current is supplied only to a valve closing coil. Thus, since the rotatable angular range of the slider 4 can be controlled in the range of 0% to 100% of the duty ratio, it is enabled to enhance the flow-rate controllability.

Abstract: PURPOSE:To reduce adverse effects of a lattice defect, by a method wherein a metal thin film pattern is formed on a compound semiconductor substrate, and under this condition, the metal thin film pattern is heat-treated, thereby to localize a denatured layer produced by the heat treatment. CONSTITUTION:On an n type GaP single crystal substrate 11, an n type GaP epitaxial layer 121 and a P type GaP epitaxial layer 122 are successively grown to produce a compound semiconductor substrate. Then, an Au-Be film 131 and an Au-Ge film 132 are formed. Then, the film 131 is patterned to form a pattern 14, and the substrate 11 is heat-treated. At this time, an ohmic contact is formed between the pattern 14 and the layer 122, and also on the rear side of the substrate 11, an ohmic contact is formed between the rear surface and the film 132. By the above-mentioned heat treatment, a denatured layer 17 is localized only at the electrode ohmic contact portion, thereby making it possible to prevent the adverse effects of a lattice defect on the p-n junction in the portions other than the ohmic contact portion of the layer 122.

Title: Transmission control system
Inventor: NAKAMURA HARUKA
IPC: G06F13/14
Filed: 1979-09-21
Abstract: PURPOSE: To make it unnecessary that each terminal device inputs and outputs address information, by adopting the constitution where each terminal device is fixed by the number of control codes.  
     CONSTITUTION: In case that CPU1 transmits data to the fourth output device, output data with three control codes added is transmitted to interface cable 14. The first output device deletes one control code and transmits output data with two control codes added to the second output device. Thus, only data comes to the fourth output device. Then, the fourth output device fetches data unconditionally. In case that the seventh input device transfers data to CPU1, only data is output to the sixth input device. The sixth input device adds a control code to receiving data and outputs data to the fifth input device. Thus, CPU1 receives six control codes and data. As a result, the input device from which data is transferred can be discriminated.

Furthermore, in the reverse feeding state where the 2nd trunk line terminal L2 is made a positive electrode, the current fed from the station is blocked by the diode 1 so as to pass through the loop current generating circuit 8. Through the constitution above, a loop current is immediately generated regardless of a call request from a terminal equipment in the normal supply state.

Abstract: PURPOSE:To contrive the improvement of the accuracy of a measured value by providing a temperature sensor on a cylinder head, and correcting a temperature at the time of detecting the cylinder internal pressure. CONSTITUTION:A temperature sensor 10 is provided on a cylinder internal pressure sensor 5 in a cylinder head 1, and at the time of operating an engine, the cylinder internal pressure and a temperature are measured simultaneously by the sensor 5 and 10.

At the time of a low load operation, it is within a temperature range of (measured temperature) < (set temperature) and thermal influence is scarcely exerted, therefore, in a coefficient setting part 14, a coefficient K is set as constant, and an actual measured value V of the output deciding part 12 is outputted as it is. On the other hand, when a temperature raises and becomes (measured temperature) >= (set temperature) by a high load operation, the coefficient K is set by a secondary function against a temperature in the setting part 14, the value of the cylinder internal pressure is corrected secondarily by a calculating part 15, a drop portion caused by heat is compensated against the output of the sensor 5, and an exact measured value can be obtained.
