IPC: G06K19/00
Filed: 1985-12-26
Abstract: PURPOSE:To enhance the profitability in an allocation to the memories of respective memory areas by successively rewriting data inputted in the second place from a record in which the data is written initially when the data is written in the record to be written in the last of a certain memory area. CONSTITUTION:When the writing data is inputted, the inputted data is stored in the designated record by a record pointer means. The data of the record designated by the record pointer means is read, and outputted by a check byte collation. Subsequently, the record pointer is increased by 1 and whether the sequence of the record designated by the record pointer is equal to the number of the records or not is decided. Herein, when it is decided to be 'YES', the contents of the record pointer are made as the address of the record of the first writing sequence. When it is decided to be 'NO', whether an address pointer is equal to the address of a record in which the data inputted in the next place is written or not is decided, and when it is decided to be 'YES', the reading of a hysteresis are completely finished, so that a flow is completed.

Title: Reproducing device
Inventor: YATOMI TOSHIYA
IPC: G11B5/584
Filed: 1994-11-30
Abstract: PURPOSE: To achieve a saving of power for an ATF circuit. CONSTITUTION: Reproduction signals which are obtained by reproducing a tape 1 having pilot signals with frequencies f1 and f2 recorded thereon by rotary heads 2a and 2b are applied to a digital ATF circuit 6 to extract f1 and f2 with BPFs 7a and 7b. The frequency components are detected separately to be converted to level signals, which are averaged using LPFs 9a and 9b and fetched into a control section 11 to determine a level difference. As result, an ATF error signal is generated indicating an off track value. A PLL circuit 13 outputs a clock CL locked in phase to the reproduction signals to be supplied to the ATF circuit 6 through a switch 14. The control section 1 turns OFF the switch 14 while the AFT circuit 6 is not required to extract the f1 and f2 to stop the operation of the ATF circuit 6 thereby enabling reducing of useless power consumption.

Title: Solid laser device
Inventor: YOSHIMURA ISAO
IPC: H01S3/10
Filed: 1994-12-01
Abstract: PURPOSE: To machine a work at high speed even high-reflectance and high- melting-point material which have been difficult to machine, by forming a solid laser device out of the two kinds of light sources comprising pulse-light and continuous-light emitting ones, and by making it output the laser beam having the advantages of both conventional CW and pulse lasers. CONSTITUTION: As a medium 2 of a solid laser, a rod YAG laser oscillator is used, and as its pumping light sources, one emitting lamp 6a and one CW-light emitting lamp 6b are used respectively. Since the solid laser can output the laser beam whose waveform is a pulse wave having a fixed bias, it can has the advantages of both CW and pulse lasers. Thereby, even high-reflectance and high-melting-point material hard to machine by only a single conventional CW laser or a pulse laser can be machined at a high speed. Particularly, in the case of welding an aluminium alloy by a pulse laser beam, the generation of the crack due to cooling just after its machining, which has been the problem to be solved in the conventional laser devices is eliminated.

Title: Overcurrent detection circuit
Inventor: OKUBO TAKAHITO
IPC: H03K17/08
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To obtain an overcurrent detection circuit in which a current can be detected by a mirror MOSFET. SOLUTION: An overcurrent detection circuit is constituted in such a way that a MOSFET whose structure is identical to that of a main MOSFET 101 is used as an element 103 for current detection. Thereby, the inclination of the saturation current-temperature characteristic of the main MOSFET 101 and the inclination of a detection level-temperature characteristic are made nearly equal. When a detection-level upper limit is set by a temperature in one arbitrary point, the overcurrent detection circuit can be designed in such a way that the non-detection of an overcurrent is not generated in the whole temperature range, and an overcurrent detection level can be designed extremely easily.

Title: Image forming device
Inventor: OTORI YASUHIRO
IPC: G03G21/14
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent image quality from being deteriorated due to the sticking of contact part of an image forming means to an image forming medium and to always form a high-quality image by preliminarily driving the image forming medium by a control means in a fixed time after a power source is turned on. SOLUTION: A CPU 10 is provided with a preliminary driving means preliminarily driving a photoreceptor drum 1 and a time counting means counting the time until the fixed time elapses after the power source of an image forming device is turned on. Then, the CPU 10 is provided with a function driving the preliminary driving means when the counting action of the time counting means is finished. Thus, since the drum 1 is preliminarily driven only in the previously set fixed time after the power source is turned on, the fixing of the contact part such as a cleaning blade 7a is released by the preliminary driving action by the CPU 10 even when the contact part is fixed to the surface of the drum 1 because the drum 1 is driven after it is stopped in a long time or it is driven in a high temperature state.  Therefore, the rotating action of the drum 1 is smoothed and the high-quality image without jitter is formed from the image of a first sheet.

IPC: G06F13/362
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To speedily perform arbitrating processing of a bus concerning an information processor with which one bus is shared by plural nodes. SOLUTION: When a common bus 40 is turned into non-used state, an arbitrate signal is supplied from an arbitration node through an arbitrate signal line 50 and all the bits of an arbitration bus 30 are turned into state of 'H'. An arbitrate signal detecting part 12a detects the arbitrate signal and reports it to an output part 12b. The output part 12b is composed of a three-state output buffer, a bit corresponding to the present part is set to 'L' and the other bits are set into high impedance corresponding to an arbitration code 12c. At such a time, since the other node to be participated in arbitration similarly outputs the arbitration code, these codes are synthesized on the arbitration bus 30.  An input part 12d inputs the synthesized result and a priority discriminating part 12e discriminates whether the usage of the bus can be acquired by itself or not in comparison with a decision ID 12f.
