Title: Thermoluminescence dosemeter reader
Inventor: HASEGAWA SHIYOUROU
IPC: G01T1/115
Filed: 1977-12-19
Abstract: PURPOSE: To enlarge measurement range so as to permit measurement of large dose as well by constituting such circuits which do not affect with each other by the combination use of a current integration method and the use of a photon counting method.  
     CONSTITUTION: The apparatus is provided with a photo electron multiplier 7 which detects thermoluminescence, a pulse amplifier 11 which separates and amplifies pulse signals from the output signal thereof and a DC amplifier 15. The upper limit of the band of the pulse amplifier 11 is restricted hy the band f c  of the amplifier itself and the lower limit by a frequency 1/2πR 2 C 1 . The upper limit of the DC amplifier 15 becomes 1/2πR 1 C 1 . The signal source impedance for the amplifier 15 becomes the parallel impedances of R 1  and C 1  and becomes high impedance with respect to low frequency, thus the insulation resistance of C 1  prevents R 2  from affecting the DC components. For the amplifier 11, the input impedance is only R 2  and R 3  prevents the input capacity of the amplifier 15 from giving influence. Hence, the two amplifiers do not interfere with each other to one photo electron amplifier and the DC components and pulse components may be selectively amplified.

Title: Constant-voltage power circuit
Inventor: KANAI TOSHIO
IPC: G05F1/56
Filed: 1978-12-11
Abstract: PURPOSE:To make it possible to set instantaneously an operation state by turning a power switch ON, by interposing a diode between a connection point between a load and resistance and the output terminal of a series control transistor. CONSTITUTION:Series control transistor Tr1 is connected in series between an astable power circuit and load 2 including components small in resistance value such as lamp 8 while it is cold. On the basis of variation in output voltage, the conductivity of Tr1 is controlled by error amplifying Tr4 and diode 10 is inserted between the connection point between load 2 and resistance 9 and the output terminal of Tr1. Consequently, when a constant-voltage power circuit gets stationary, the across voltage of lamp 8 is equivalent to a difference between the output voltage of a radio voltage and the constant forward voltage of diode 10 and lamp 8 is applied with a stabilized voltage. Therefore, an operation state can instantaneously be set by turning the power switch ON.

Abstract: PURPOSE: To uniformalize the pressure contact between a friction plate and a paper-feeding roller in the direction of width by providing the friction member arranged on the lower surface of the paper-feeding roller in such a manner that it is shakable in the direction of the width of the roller.  
     CONSTITUTION: A friction member supporting plate 10 fitted with the friction member 6 is arranged at the opening part of a guide plate 4 so that they do not contact with each other, while the base end part of the supporting plate 10 is fixed to a bush 7a which is fitted in a member 7 and rotatable around an axis 7b. By this, the friction member 6 is pressed on the paper-feeding roller 5 by a spring (not shown in the figure) and simultaneously becomes capable of shaking in the direction of the width of the roller 5. Thus, the pressure contact turns to be uniform, whereby the feeding of leaf can be performed smoothly and such troubles as double feeding or jamming of paper caused by bending of paper sheets can also be prevented.

Title: Image forming system, sheet stacking method, sheet post- processor, image forming device and storage medium
Inventor: OKI KENJI
IPC: B65H39/11
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To provide an image forming system having a constant stackable amount regardless of a curl amount of discharged papers to stack a constant number of the papers on a tray. SOLUTION: In the case of the presence of a large-size paper on a tray, full stacking data B are used as a value for deciding full stacking by use of a distance and a paper number as well as in mixed stacking (S11103). The stacking number of the tray in present use is compared with the specified full stacking number of the tray (S11107). In the case that the stacking number is short of the full stacking number, α is added to full stacking distance data to update the full stacking distance data for deciding the full stacking (S11108). Then, a stacking state rate of the stacked papers is calculated by use of the data (a distance, a paper number and paper information) (S11109). It is decided on the basis of the calculated value whether a present stacking state is the full stacking or not (S11110).  In the case of the full stacking, a copying operation is forbidden (S11111), release of the full stacking is waited (S11112). When the full stacking is released, the forbiddance of the copying operation is released (S11113).

Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To provide an information recording device in which recording conditions are precisely set while reproducing test signals by appropriately setting the conversion range of an A/D converter. SOLUTION: When test signals recorded in the PA of a DVD-R20 of the information recording device is reproduced, the reproduced signals are converted into digital data by an A/D converter 30. The data are held in a buffer memory 34 for every signal kind through a data separating section 33. Then, a CPU21 detects a peak value and a bottom value of signal waveforms employing the data of the memory 34. Based on these values and considering a margin, computations are made for upper limit level data to be set in a first D/A converter 31 and lower limit level data to be set in a second D/A converter 32. Then, the level data are converted into analog signals by the converters 31 and 32 and are applied to the conversion range setting terminal of the converter 30.  Thus, the conversion range of the converter 30 is set to an optimum range in accordance with the amplitudes of the reproduced signals and an A/D conversion is conducted in the converter 30 with a proper resolution.

Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To actualize the human stream measuring instrument which can precisely measure the number and moving directions of pedestrians and the degree of congestion even at the time of congestion. SOLUTION: Image pickup devices 103 installed at a staircase at some elevation angle pick up images of pedestrians 102 who go up and down the stairs 101. The images are inputted to a correspondence part 105 to obtain parallax data. The parallax data are converted by a parallax-distance conversion part 106 into distance data. A recognition part 107 separate the pedestrians individually by using the distance data to recognize their positions. A counting part 110 traces the recognized positions of the pedestrians with the time and counts them when they pass a count line. The pedestrians are recognized and traced by using the stereoscopic images having a small dead angle, so the number and moving directions of the pedestrians and the degree of congestion can accurately be measured even in the case of congestion.

Title: Electrothermal recording method
Inventor: KATAOBE NOBORU
IPC: B41J2/37
Filed: 1986-07-01
Abstract: PURPOSE:To enable a uniform printed density and a higher recording speed, by dividing recording electrode needles into a plurality of small blocks, driving the blocks on a time-sharing basis, enabling the width of energizing pulses to be varied according to the number of the electrode needles simultaneously energized in each of the blocks, and enabling the energizing period for all of the recording electrode needles to be varied according to the pulse width. CONSTITUTION:Symbols B1-B4 represent divisional blocks of recording electrode needles 5. The recording electrode needles 5 in the same block are energized with the same timing, whereas those in different blocks are driven with staggered timings. Symbols T1-T4 represent widths of energizing pulses for the blocks, respectively. The pulse widths T1-T4 are set to be shorter or longer according as the number of the recording electrode needles 5 simultaneously energized in the same block is smaller or greater, whereby a resistor at each heat generating part is supplied with a constantly fixed quantity of energy. When energization of the block B1 is completed, energization is immediately switched to the block B2, then to the block B3, and so on. Therefore, the period of time To1, To2, To3,... required for completing printing in one line varies depending on the energizing pulse widths T1-T4. Accordingly, the energizing period for printing characters of images is shorter then that for printing an all area.

IPC: C22B1/20
Filed: 1991-06-26
Abstract: PURPOSE:To prevent disintegration of pseudo-particles of hot returned ore at a low cost and to prevent the reduction of sintered ore throughput. CONSTITUTION:Hot returned ore supplied from a hot screen 4 in a sintered ore producing equipment 1 is fed for resintering from a hopper 5. A water spray or blast equipment 7 is provided to the rear step of the hopper 5 and also in the front step position of a mixing and granulating stage 6 for resintering. Water spray or air blasting is performed for the hot returned ore fed from the hopper 5. This hot returned ore is cooled to the temp. of the same degree as the other raw material for mixing the hot returned ore. Before mixing and granulation for resintering are performed for the hot returned ore, the same is cooled. Moisture stuck to the pseudo-particles is prevented from becoming such a state that the temperature of this moisture is raised and it is easily vaporized. Thereby the pseudo-particles are prevented from being disintegrated by shock in a carrier course which is caused by vaporization of the constitutional moisture of the pseudo-particles. Reduction of sintered ore throughput caused by disintegration of the pseudo-particles is prevented.
