Title: Memory access controlling system
Inventor: MAEDA HARUMICHI
IPC: G06F13/16
Filed: 1983-10-31
Abstract: PURPOSE:To fetch an instruction at a high speed by comparing an output of a register for latching a low address from a CPU by fall of an RAS signal, with a low address sent out in the next time from the CPU. CONSTITUTION:A low address sent out of a CPU is latched to a register 2 by fall of an RAS signal. An output of this register 2 and a low address sent out in the next time from the CPU are compared by a comparator 3, and a coincidence signal is supplied to an RAS/CAS control part 4. This RAS/CAS control part 4 supplies only a CAS signal to a control storage part 1 by a coincidence output of the comparator 3, and instructs access by a page mode. Also, when an output of the comparator shows dissidence, the RAS signal is raised once, and the next instruction is fetched.

Title: Metal collecting method by electrolysis
Inventor: SHIMAMUNE TAKAYUKI
IPC: C25C7/02
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To reduce an energy consumption while keeping a purity of a collected metal in a conventional electrolytic metal collecting method capable of collecting a high purity metal but high in energy consumption. SOLUTION: A gaseous mixture of methanol and water is supplied to a fuel cell by using an anode adhered to an ion exchange membrane at an anode chamber side as the fuel cell without changing a construction of an cathode chamber side precipitating a metal in a conventional metal collecting electrolytic cell. In this method, a purity of an obtained metal is kept in high as it is since a metal collecting side, that is the cathode side, is in a conventional manner, and a reduction of a corresponding amount of an energy consumption is attained since an anodic reaction is changed to a hydrogen ion generating reaction hardly causing a generation of oxygen from an oxygen generating reaction by adopting the fuel cell.

Title: Frequency characteristic switching type difrerential amplifier
Inventor: MIYANO YUICHI
IPC: H03F3/45
Filed: 1984-09-29
Abstract: PURPOSE:To reduce the value of a phase compensating capacity, and to improve a high band characteristic and a through rate by constituting a titled amplifier so that an open loop gain is also switched to make stable condition constant when switching the frequency characteristic of an amplifying circuit. CONSTITUTION:When a switch SW1 selects a power source line 12 side, a current I0 flowing to a current source 13 becomes equal to a current I1 flowing to a transistor QC by a current mirror operation by a transistor QB, diode 15, and the transistor QC, and the first amplifying circuit only is operated. When the switch SW1 selects a ground line 12 side, a transistor QA and a transistor QB are turned on and off, respectively, and a current I2 flows to a transistor QD. In such a case, since I1=0, the second amplifying circuit only is operated.

Title: Controller for temperature of photosensitive body
Inventor: OHASHI KUNIO
IPC: G03G21/20
Filed: 1985-09-17
Abstract: PURPOSE:To relax temperature stress with respect to a photosensitive body or a developer by controlling a heater so that the temperature of a photosensitive drum can be higher than the outside air temperature measured by an outside air sensor by the prescribed degree. CONSTITUTION:The thermister Rt1 (3) of a temperature control circuit 5 measures the surface temperature of the photosensitive drum 1, while a thermister Rt2 (6) measures outside air. A comparator COMP compares a voltage at a point (a) with that of at a point (b). When the former is higher than the latter, the voltage of an output at a point (c) is set to 'H'. Conversely, when the former is lower than the latter, the voltage at the point (c) is set to 'L'. When the voltage at the point (c) is at 'H', a heater drive circuit 4 turns on the heater 2, and controls it so that the voltages at the points (a) and (b) can be equal. By adjusting a variable resistance VR, the voltages at the points (a) and (b) are equalized when the temperature of the photosensitive drum 1 is higher than outside air in a range of several  deg.C-20 deg.C.

Title: Voltage generating circuit
Inventor: MATSUKI HIDEO
IPC: H03F1/26
Filed: 1994-08-30
Abstract: PURPOSE: To obtain a voltage generating circuit starting slowly the rising of a constant voltage outputted from itself with a simple configuration. CONSTITUTION: A slow start capacitor C is provided to a reference voltage circuit 20 to slow down the rising of a reference voltage VREF outputted to a constant voltage circuit 14. Furthermore, a differential amplifier 10 of the constant voltage circuit 14 receiving the reference voltage VREF is operated from the rising (e.g. at 0V) of the reference voltage VREF and provides the output of a constant voltage +VO corresponding to the reference voltage VREF. Thus, the constant voltage +VO outputted from an output TR Q9 rises slowly. When the voltage generating circuit is applied to the power supply circuit of an audio signal processing system or the like without the effect of the capacity of a load in an operation circuit or the like receiving the constant voltage +VO, it is prevented that the production of pop tone noise or noise is generated at application of power.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a mirror barrel test equipment that measures stably presence of an image shake of a mirror barrel automatically at a high speed not relying on a visual sensory evaluation. SOLUTION: A mirror barrel 1 consists of a zoom lens magnifying an image of an object and a focus lens focusing the object or the like. A chart 2 including information of reference points R, S is placed at a position opposite to the mirror barrel 1. An image of the chart 2 is photographed and a video signal by one frame is stored. A reference point detection means 7 applies arithmetic processing to pixel data stored in an image memory means 6 to detect the positions of the reference points R, S. A zoom control means 8 moves the zoom lens of the mirror barrel 1 to control zooming. An image shake detection means 9 calculates a locus of the reference points during zooming and a line segment resulting from straight line approximation of the locus and discriminates whether or not the locus is entirely within a prescribed range with respect to the straight line.  Thus, the presence of image-shake during zooming is detected.
