Abstract: PURPOSE:To always keep relation between picture data and recording density in constant invariably, by providing a measuring means which decides picture density outputted to the picture data, and correcting the picture data based on the output of the measuring means. CONSTITUTION:Each optical image condensed on a contact type color CCD sensor 11 in an image reader 121 is changed to an electrical signal by every color, and is transmitted to a signal processing substrate 16. And after it is transmitted from the signal processing substrate to an image processor 124, and a prescribed image processis performed, it is transmitted to a printer 122. At a gradation control circuit 1300 in the printer 122, data corresponding to the picture density can be obtained, and a laser is modulated. At this stage, the picture density is measured by a potential measuring unit 138, and based on a measured result, the picture data corresponding to the picture density is corrected. In this way, it is possible to keep the relation between the picture. data, and the recording density in constant invariably, even when the characteristic of a photosensitive body changes.

Title: Measuring method for tape run time
Inventor: OKADA YOSHINORI
IPC: G11B27/17
Filed: 1978-11-06
Abstract: PURPOSE: To display the remaining time of a VTR tape, etc., without reference to a rapid traverse tape speed, etc., by detecting the tape run speed from a difference in period of continuous double rotation of a take-up reel.  
     CONSTITUTION: The rotation period of a supply reel or take-up reel is measured twice continuoulsy and a tape run speed is obtained by the expression of measured values Δt(n) and Δt(n+1), and tape thickness D given by v=2πD/[Δt(n+1)- Δt(n)]. This run speed and detection values of rotation angular speeds of the take- up and supply reels are inputted to a microcomputer, so that remaining time T 1  of the supply reel can be displayed as not the rotational frequency of the reel but time with good precision. Total tape time T 0  may be inputted previously and use time T 2  can be displayed as T 0 -T 1 =T 2 .

Abstract: PURPOSE:To obtain distinct two-color image having sufficient density by making the intensity of a laser beam from an irradiation means in a poststage stronger than that of the laser beam from the irradiation means in a prestage. CONSTITUTION:By considering the potential difference between electrifying means in every set of image forming means and the difference of developing characteristic caused by the difference of the developing bias of developing means, the intensity of the laser beam from the irradiation means in the poststage is made stronger than that of the laser beam from the irradiation means in the prestage. Namely, based on the potential difference between a 1st electrifying unit 201 and a 2nd electrifying unit 204 and the difference of developing characteristic between the 1st developing unit 203 by the developing bias of superposed voltage of DC component and AC component and the 2nd developing unit 206 by the developing bias of only DC component, the power of the 2nd laser beam 310, on the 2nd developing condition, is controlled to be stronger than the power of the 1st laser beam 309. Thus, the distinct two- color image having sufficient density can be obtained.

Filed: 1986-06-13
Abstract: PURPOSE:To improve the resolution of a fine pattern, and to enhance the precision of drawing by exposing the edge section of a large pattern and other patterns first and exposing a residual section in the large pattern and a small pattern. CONSTITUTION:Beams of electrons (e<->) are generated from the inner surface of a window 13 by beams from an LED projected to the outer surface of the window 13 consisting of AgCs, and the upper section of a sample 18 is irradiated by beams of electrons and exposed to a predetermined pattern. When the inside of a region of 20mum one side includes a large pattern and a small pattern and configuration is required, an edge section shown by an oblique line in a pattern I and a pattern III are exposed at a first step, and a pattern 11 is not exposed. The inside (oblique line) of the pattern I and the pattern II are exposed. Consequently, 'a blur' by the Coulomb's repulsive force of beams of the pattern l is eliminated, and, 'blurs' by a proximity effect between the patterns I and II and the patterns II and III are also removed. Acoordingly, processes are divided so as not to simultaneously expose approaching patterns, thus improving accuracy.

Abstract: PURPOSE: To obtain a soft alloy for sealing glass giving sufficient adhesion strength with a thin oxide film by specifying the ratio of the Mn content to the Si content in a Cr-Zr-Si-Mn-Fe alloy having a estricted composition.  
     CONSTITUTION: This soft alloy for sealing glass consists of, by wt., 15W30% Cr, 0.05W2.0% Zr, 0.1W0.5% Si, 0.2W1.0% Mn and the balance Fe with inevitable impurities while regulating the ratio of the Mn content to the Si content to 1W8.

Filed: 1994-06-20
Abstract: PURPOSE:To easily reduce the variation of the secondary voltage of a power unit resulting from the variation of the primary voltage of the power unit even when such a constant voltage circuit as the constant voltage transformer, etc., is not provided on the primary side. CONSTITUTION:The primary voltage V1 of input power supply 30 is detected as a DC voltage V3 between the terminals of a smoothing capacitor 26 through an insulating transformer 24 and rectifying diode 25. The capacitor 26 is connected in series with a reference power source 18 so that the voltage V4 of the power source 18 can become opposite in polarity and the voltage difference (V4-V3) is inputted to a comparator 19 as a reference voltage VS through a potentiometer 27. When the secondary-side charging voltage v2 starts to rise due to the variation of the primary voltage v1, the rise of the voltage v2 is suppressed, because the reference voltage VS drops. When the voltage v2 starts to drop due to the variation of the voltage v1, on the contrary, the drop of the voltage v2 is suppressed, because the reference voltage VS rises.

IPC: G11C11/411
Filed: 1978-11-07
Abstract: PURPOSE:To realize a high-speed read by setting more than two kind of threshold levels for a comparison of a potential of a bit line in read operation. CONSTITUTION:Control lines A and A' are set to E(A)>Eth>>E(A') where a constant threshold level is denoted Eth. For example, when transistor TrQC1 of memory cell CEL11 is held ON and QC2 OFF, the base potential of TrQC1 is -1.7V and that of QC2 is -2.0V. When word line W1 and bit lines B11 to B14 are selected, base potentials of TrQC1 and TrQC2 increases up to -0.9V and -1.5V, for example, as word line W1 increase in potential. Consequently, 2nd and 3rd emitters of Trs QC1 and QC2 are fed with currents, but the collector potential of TrQR12 rises earlier because of E(A)<E(A'). Therefore, while the base potential of TRQC1 is in process of rising, an output is obtained at an intersection with potential E(A1), but timing is made earlier than Eth.
