Title: Digital copying device
Inventor: SAKANO YUKIO
IPC: H04N1/405
Filed: 1985-10-31
Abstract: PURPOSE:To obtain an excellent copy of even an original where a halftone image and a binary image are both present and to prevent moire from being generated by discriminating between a halftone image and a binary image as to each area on the original and switching both automatically. CONSTITUTION:Signals outputted to a recording means are switched automatically according to the decision result of an area decision means 70 which decides whether an original image is a halftone image or not. Namely, a signal after halftone processing when the area decision means decides the presence of halftone information or a simply binary-coded signal when the means decides the absence of halftone information in selected. The area decision means is equipped with a dot detecting means which detects whether or not an array of black-level or white-level picture elements of the original image is in a dot shape or not and when a dot is detected,the halftone processing of the image is performed. When the signal after the halftone processing is selected, halftone density is reproduced in a recording image and when the simply binary-coded signal is selected, the density of the recording image is binary. Further, when the original image is a dot image, a signal obtained by reading the image is subjected to halftone processing, so the generation of moires is suppressed.

Title: Automatic density adjusting device for image forming device
Inventor: AOKI MINORU
IPC: G03G15/00
Filed: 1986-10-17
Abstract: PURPOSE:To adjust picture density with high precision by generating a density adjusting signal based on a value obtained by subtracting the density detection value for absence of an original from the original density detection value detected at the time of detecting the original density. CONSTITUTION:A value V0 of a circuit output Vout corresponding to a quantity F0( FN) of light for absence of the original is stored in an NVRAM 24 correspondingly to the running position of a scanner. In case of original density detection, an original density voltage V0D(=Vout-V0) is calculated by a CPU 26 in accordance with running of the scanner. That is, a maximum value V0DMA of the voltage V0D is obtained in a density detection range C (during running for a certain distance), and a developing bias voltage VB is determined in accordance with a figure indicating relations among the original density voltage V0D, the detection value V0DMA, and the developing bias voltage VB. The timing when the value V0 is inputted into the NVRAM 24 is allowed to coincide with the timing of original density detection (the scanning position of the scanner) and numbers of times of input are equalized, and its is sufficient if numerical values are inputted to the NVRAM only once at the time of manufacturing a device.

Title: Internal operation observing circuit
Inventor: TSUNODA KAZUHIRO
IPC: G01R31/28
Filed: 1990-09-14
Abstract: PURPOSE:To observe the internal operation of a large scale integrated circuit using a reduced number of input and output terminals by providing a shift register having arbitrary bit length capable of writing an internal observation signal, an external input terminal indicating the writing of the internal observation signal or shift operation and an external output terminal outputting the value of the most significant bit of the shift register. CONSTITUTION:Since a logical value 0 is usually inputted to an external input terminal 30, a shift register 20 successively shifts the logical value 0 inputted from the most significant bit to output the same to the external output terminal 30 from the most significant it. Next, when the terminal 30 is set to a logical value 1 in arbitrary timing, the register 20 stops shift operation to write the operation observing signal in a large integrated circuit 10. Herein, when the terminal 30 is returned to the logical value 0, the register 20 starts shift operation and the written observation value is successively outputted to an external output terminal 40. By this method, each state value in the circuit 10 can be observed by the terminal 40.

Title: Damping device for machine base
Inventor: YAMADA MASAAKI
IPC: F16F15/02
Filed: 1989-09-21
Abstract: PURPOSE:To enable damping over the whole frequency zone by supporting each beam of a frame with a supporting table fixed to the lower surface of a machine base and a supporting table fixed to the upper surface of a construction rotatably around a horizontal axis and rotatably around a vertical axis with each of the supporting tables as supporting points. CONSTITUTION:When a machine base 1 is pushed down in the vertical direction, a beam 14 supported by a supporting table 7 of the base 1 is pushed down, and center axes of the beams 14 and 15, that is, a support axis of a frame 11 is made in the inclined state against the X axis. This movement is detected by a heavy bob 12 rotating at high speed, and the frame 11 is rotated around the support axis. This rotation causes a moment M around the Y axis at right angles to the support axis, which acts as couple of force for lifting up the supporting table 7 of the base 1 vertically upward, and displacement of the base 1 vertically downward is offset and eliminated. To the contrary, when the base 1 is lifted up vertically upward, couple of force for pushing down the supporting table 7 vertically downward acts due to the same operation as above.

Title: Fuel feed device for engine
Inventor: HARADA SHINICHI
IPC: F02M69/00
Filed: 1986-10-17
Abstract: PURPOSE:To provide a fuel injection device which can regulate disorder of fuel pressure regulation due to a change in line resistance or a fuel return passage and the inner pressure of a fuel tank, by providing a pressure regulator in a fuel passage situated down a line from a fuel pressure regulator. CONSTITUTION:When a fuel pressure in a return passage 34 is increased, the pressure thereof is exerted on a fuel chamber 30 of a fuel pressure regulator 27 to increase a fuel pressure, which is exerted on a regulating chamber 36 of a pressure regulator 29 through a weighing part 28. However, since the abnormal fluctuation or the return passage 34 is propagated through a passage 40 to a back chamber 38 of the pressure regulator 29, a pressure equivalent to the increase is offset by means of the two surface of a diaphragm 37, and the pressure regulator 29 regulates a fuel pressure to its initial value at which the fuel pressure regulator 27 is controlled by a suction negative pressure. When a fuel pressure in the return passage 34 is decreased, the fuel pressure is regulated in a similar manner described above. Even when the fuel pressure is controlled by means of a venturi negative pressure, an abnormal fluctuation is offset by means of the two surfaces of the diaphragm of the pressure regulator to regulate a fuel pressure to a normal value responding to a venturi negative pressure.

Title: High-frequency switching type rectifier
Inventor: SAITOU MASAYOSHI
IPC: H02M3/28
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To obtain a highly efficient high-frequency switching type rectifier by allowing the output voltage to be controlled at a constant voltage in a range of ratio where an on-time is longer than an off-time when a pulse width modulation control is taken place. SOLUTION: When a commercial AC power supply is applied to power input terminals 1 and 2, the input voltage is converted into high frequency by interrupting a two-way switch S1 and it is applied to a high-frequency transformer T1. Then it is rectified by diodes D1 and D2 and smoothed by a capacitor C2, and it is outputted as DC power from output terminals 3 and 4 thereafter. Further, a voltage detection circuit 5 compares the voltage of load connecting to the terminals 3 and 4 with a reference voltage, and it inputs an error voltage into a PWM circuit 6 through a photocoupler Q2, then the driving pulse of the switch S1 is controlled by the error voltage so as to stabilize the load voltage.  As a result, a commercial AC power supply can be switching-controlled directly through a switching means without rectifying and smoothing the commercial AC power supply and be applied to a transforming means in order to rectify and smooth the output, therefore high efficiency can be obtained.
