Filed: 1985-09-06
Abstract: PURPOSE:To binary code the multi-value picture data so that the character pictures can be read sharply out of the background pictures, by using a means to binary code the character picture data and a means to binary code the picture data excepting for characters. CONSTITUTION:For the multi-value picture data to be binary coded, the picture data of only characters and other picture data are stored in multi-value data memories 1 and 4 respectively. Then these picture data undergo the different types of binary coding processing through binary coding parts 2 and 5 respectively and these two different binary data are stored in binary memories 3 and 6. Then the contents of the memory 6 are rewritten at a character superposition processing part 7 with priority at the area corresponding to the characters of the contents of the memory 3. Thus two binary data are synthesized and stored in a binary picture memory 8. In such a way, the binary data which can read sharply the characters are obtained, when the pictures are printed.

Title: Method for automatically detecting fluctuation of height of coke bed in cupola
Inventor: MIYAKE YASUO
IPC: G01B13/00
Filed: 1990-07-25
Abstract: PURPOSE:To stabilize to a high degree the molten components of cast iron obtained from a cupola by calculating the difference between the total amount of carbon put in the cupola and that of carbon discharged from the cupola, so as to calculate the fluctuation of carbon in the cupola. CONSTITUTION:The mass of carbon in a cupola is balanced e.g. every ten minutes. The total amount FCW of carbon put in the cupolar, including raw base metal and coke, is calculated first and then the total amount OCW of carbon discharged from the cupola is calculated. The difference between those values is calculated so as to find the fluctuation OCW of carbon in the cupola. In calculating the total amount OCW of carbon, the value of the amount of carbon in a molten metal which is anticipated from the raw base metal and coke put in the cupola is used to calculate the total amount of carbon discharged from the cupolar according to the anticipated amount of carbon in the molten metal and the amount of carbon contained in exhaust gas. The amount of carbon in the molten metal is thus anticipated and calculated so as to promptly detect the fluctuation of the height of a coke bed and to promptly take measures against the fluctuation.

Title: Digital signal processor
Inventor: KAGA MITSURU
IPC: G06F17/10
Filed: 1984-09-25
Abstract: PURPOSE:To obtain a highly accurate digital signal processor with simple constitution with no overflow of output, by reducing the scale of the output of a multiplier in a sum-of-product operation. CONSTITUTION:A multiplier 11 of a digital signal processor performs multiplication of an input signal (12 bits) and delivers an output signal S1 (16 bits). This signal S1 is applied to a right shift unit 12 to have a right shift of 2 bits and then applied to one side of an adder/subtraction 13. While a multiplexer 17 selects a signal between the output S2 (16 bits) of the unit 12 and the output S1 (16 bits) of the multiplier 11 and applies it to the other side of the adder/ subtractor 13. Then the output signal S3 (16 bits) of the adder/subtractor 13 is applied to a totalizer 14. The output signal S4 of the totalizer 14 is applied to one side of the multiplexer 17 as well as a data bus 19. The output of the multiplier 11 is shifted by 2 bits and applied to the adder/subtractor 13. This prevent the overflow of the result of totalization and improves the arithmetic accuracy of a digital signal processor of simple constitution.

Title: Temperature compensating circuit
Inventor: SHINOMIYA KOJI
IPC: H03F1/30
Filed: 1987-08-07
Abstract: PURPOSE:To facilitate the semiconductor circuit integration, to reduce the cost and to improve the accuracy by setting the temperature characteristic of the 1st, 2nd and 3rd constant current sources so as to obtain a current independently of the temperature, an input signal current proportional to the absolute temperature T and a current proportional to the absolute temperature respectively thereby adding or subtracting the base-emitter voltage of each transistor(TR). CONSTITUTION:Let constant currents of constant current sources 1, 2, 3 respectively be IRFE, II and IT, then the relation of ICQ7=ICR4XIEQ5/ICR6 exists, where ICQ4 is the collector current of a TR 4, IEQ5, IEQ6 are emitter currents of TRs 5, 6, and ICQ7 is a collector current of a TR 7. Then a constant current independently of the temperature (IRFE) is set as the ICQ4, IC31 is set as IEQ5 and IT is set as IEQ6, then the relation of ICQ7=IRFEXIC31/IT is obtained. Since the IREF is a constant current independently of the temperature, IT is c current proportional to the absolute temperature T and the 1C31 is a current proportional to the absolute temperature T, the absolute temperature T is cancelled and the ICQ7 is made independent of the temperature and constant.

Title: Variable focus liquid crystal lens
Inventor: SHIMAZU HISANO
IPC: G02F1/13
Filed: 1987-08-08
Abstract: PURPOSE:To remove the double focus image by unequal orientation by disposing a polarizing plate to the side of a transparent substrate which has a more uniformly oriented surface, of two sheets of the transparent substrates. CONSTITUTION:The polarizing element 2 is disposed on the side of the one transparent substrate 1A, i.e., the substrate 1A subjected uniformly to the orientation treatment, of two sheets of the transparent substrates 1A, 1B. Only the extraordinary ray component is thereby allowed to enter the liquid crystal molecules on the substrate 1A side and, therefore, even if the nonuniformly oriented part 1C exists on the substrate 1B side opposite thereto, the liquid crystal molecules emit only the extraordinary ray component by their optical rotary power. The double images by the irregular orientation of the liquid crystals are no longer visible by an observer 5.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of forming a plurality of images by a single image forming operation and making the removal of a jammed paper sheet easy. SOLUTION: Image forming process parts comprising electrifying chargers 50a and 50b, developing units 51a and 51b and transfer chargers 54a and 54b are arranged to correspond to two image forming positions Sa and Sb on the surface of a photoreceptor drum 47, respectively.

When it is enough to use only the carrying path on one side, the carrying path on the front side is always selected, to form the image.  In such a case, even if a paper sheet is jammed, an opening/closing door for maintenance on the front surface of a copying machine main body is opened to easily remove the paper jammed on the carrying path, because the paper is jammed on the front side.

Abstract: PURPOSE:To prevent developer from being supplied one-sidedly by stopping driving a developer carrying means when the amount of developer is equal to or over a specified value. CONSTITUTION:Not only the developer 4 is stored but also impellers 7, 8 and 9 having a blade functioning as the developer carrying means are provided in a developer container 3. A torque limiter 10(10a, 10b and 10c) such as a spring clutch is disposed between the shaft of the impeller and the shaft of a gear for driving the impeller. The impellers 7, 8 and 9 are driven and rotate in a direction shown by an arrow by linking with a developing sleeve 2 and a supplying roller 5 by the torque limiter 10 and the gear, etc. When the devel oper is carried toward the roller 5 and collected to be accumulated, pressure exerted to the blade is increased, and the torque limiter becomes off, then the rotation of the impeller is stopped and the supply of the developer is also stopped. On the contrary, the supply of the developer is started by starting the rotation of the impeller. Thus, the developer is prevented from being floculated and is not one-sided with a developing sleeve side, the irregularity of rotation is prevented, and a clear image is obtained.
