Title: Electrostatic recording method
Inventor: KITSUI TOSHIKAZU
IPC: G03G15/00
Filed: 1991-06-28
Abstract: PURPOSE:To prevent the stain on an image due to remaining developer in a developing device when color image recording is excuted with a notary developing device. CONSTITUTION:Developing position is one developing device 19a and electrostatic recording paper 10 is sent in a recording direction (A direction) and recorded then developed. Thereafter the developing device 19a is moved to the opposite direction of the recording and the developing position is center position between the developing receptacle 19a and next developing receptacle 19d, then in this state, the electrostatic recording paper 10 is unwound. In such a manner, the drying groove side of the developing receptacle 19a used immediately before makes an approach to the electrostatic recording paper at the time of the unwinding of the electrostatic recording paper. Since little developer remains at the drying groove side, the stain on the image part of the electrostatic recording paper by the remaining developer is not generated.

Abstract: PURPOSE:To maintain the weld quality constant by inserting a capacitor between an output end of a DC/AC conversion circuit and the primary side of a step- down transformer and making frequency of the AC output voltage of the conversion circuit variable. CONSTITUTION:The capacitor 15 is inserted between the output end of the DC/AC conversion circuit 4 and the step-down transformer 5 and a variable resist 16 for setting the frequency is arranged to a triangular wave oscillator 11a. The capacity 15 cuts the DC contained in the output of the circuit 4 and furthermore, a welding current is sufficiently maintained in the upper limit of the variable frequency by the insertion of the capacitor 15 by this mechanism. Accordingly, since the deviated magnetism of the transformer 5 is prevented by the capacitor 15 and a frequency variable means is provided, the output frequency of the circuit 4 can be changed according to the welding speed. The weld quality is always maintained constant by this method.

Title: Production of coffee
Inventor: OTA TOSHIYUKI
IPC: A23F5/24
Filed: 1990-06-18
Abstract: PURPOSE:To obtain coffee having excellent flavor readily, productively and economically, extracting roasted and finely ground coffee beans with low- temperature water to give coffee essence and forcedly filtering the coffee essence. CONSTITUTION:Roasted and finely ground coffee beans are extracted with low-temperature water while stirring. The extracted solution is forcedly filtered to give a low-temperature aqueous solution of coffee essence. When the roasted and finely ground coffee beans are stirred in low-temperature water, the coffee essence is extremely rapidly extracted even if water temperature is low. Moreover, since the coffee essence is extracted with low-temperature water, only components of preferable flavor are extracted. The roasting is carried out by a conventional procedure and a method of uniformly roasting to the central part such as infrared light roasting or roasting with charcoal fire is proper. When the low-temperature aqueous solution of the coffee essence is freeze dried, prepared coffee has extremely higher productivity than coffee extracted with hot water and this compound is economically preferable.

Filed: 1990-06-18
Abstract: PURPOSE:To confine the noise inside an independent power system only in the power system by cutting the power line inside the basic I/O cell. CONSTITUTION:A power line 104 lies on a basic I/O cell, and is constituted by arranging basic I/O cells 103 adjacently. A power line 105 is the same as the basic I/O cell 103, but one part included the basic input cell 103 is cut, and so therein the current does not flow in the direction of being connected adjacently, and constitutes an independent power system which has basic I/O cells on both sides 106. The power line 105 is an independent power system, and even if a large instantaneous current flow in the basic I/O cell 103 or 106 inside this power system, the noise appearing in the power supply is completed only in this power system. Therefore, if basic I/O cells 103 or 106 wherein noise is apt to occur are provided collectively in the independent power system, than the effect on others can be avoided to the utmost.

IPC: H05B41/32
Filed: 1987-06-26
Abstract: PURPOSE:To shorten a light emission waiting time and to emit light in plural light emitting modes by permitting a charge and discharge control means to control plural capacitors so that they begin to charge and are prohibited from charging with time lag. CONSTITUTION:The 1st and 2nd capacitors 24 and 12 supplying electric charges to a discharge tube 21 and the charge and discharge control means are provided.

Title: Recognition judgement device
Inventor: SAKAGAMI SHIGEO
IPC: G06N3/00
Filed: 1992-06-18
Abstract: PURPOSE:To provide a recognition judgement device where time required for calculating an output category is short for an input feature vector and a parameter can automatically be optimized. CONSTITUTION:At the time of outputting the category to which a twodimensional input feature vector (x, y) belongs, a first threshold comparator outputs the selection signal of a second threshold comparator when a feature element (x) is smaller than a threshold t1, and outputs the selection signal of a second attribute memory B when the feature element (x) is more than the threshold t1. The threshold comparator where the selection signal coincides with the value of the peculiar selection signal or an attribute memory executes the processing of a next stage, and the threshold comparator outputs one of the two selection signals in the same way as the operation of the first threshold comparator. The attribute memory outputs the category and recognizes and outputs the category to which the input feature vector belongs by repeating the comparison of the sizes. Thus, the time required for the calculation of the output category is shortened since the output category can be obtained only by the comparison of the sizes.

Abstract: PURPOSE:To improve the light confining characteristic in the lateral direction, by forming a cylindrical convex or concave part on the surface of a substrate, imputting different constituent molecules in the vertical direction and in the slant direction with respect to the substrate, and changing the refractive index in the lateral direction. CONSTITUTION:A photoresist film 9 is formed in a stripe forming region of an n-type GaAs substrate 1. Then the film 9 is baked at a high temperature. The film 9 is converted into a photoresist film 9a, which forms a cylindrical convex (or concave) part. With the film 9a as a mask, unidirectional etching is performed, and a cylindrical convex (or concave) part 1a is formed on the surface of the substrate 1. Thereafter, GaAs is imputted in the vertical direction toward the central part of the convex part 1a, and Al is inputted in the slant direction. Thus AlxGa1-xAs layers 2a-6a and 10 [(x) is 0 for the layers 4a and 10] are formed. In this process, the mixed crystal of the layers 3a and 5a is small at the central part of a stripe and becomes larger as the distance from the central part becomes longer. The refractive index becomes smaller as the distance from the stripe becomes longer. Thus the light confining characteristic in the lateral direction is improved.
