IPC: G11C27/02
Filed: 1981-12-18
Abstract: PURPOSE:To carry out sample holding operation accurately without exerting any influence of the floating capacity of semiconductor switching elements by specifically adjusting the floating capacity of the semiconductor switching elements which are applied with an positive phase and an negative phase signal at input sides respectively and connected in common at output sides. CONSTITUTION:The output of a differential amplifier is inputted to the drain of a switching MOSFET6A having floating capacity CDS1, and an out-of-phase signal is inputted to the drain of a switching MOSFET6B which is formed in the same process with the FET6A and has floating capacity CDS1; the sources of the FETs 6A and 6B are connected to a holding capacitor 8 in common. Those FETs 6A and 6B are adjusted in gate width so that CDS1 =1/Gx(CDS1), and then values irrelevant to the capacities CDS1 and C'DS1 are obtained at the output sides to perform accurate sample holding operation. In the equation, G is the gain of a signal path.

Title: Image reader and image forming device
Inventor: KAMATA TAKASHI
IPC: G06T3/60
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To obtain an image in accordance with the intent of a user by storing the read image data after applying a rotational processing to them if an angle of rotation is inputted from an external input means. SOLUTION: The image data which are read out of an original set on a platen are stored in an image memory 34. A tilt detection means 35 detects the edge part of an image and sends it to a tilt angle control means 37 if the detected edge part has a tilt. A rotation processing means 36 applies the rotation processing to the image data of the memory 34 via a technique such as the affine transformation or shift processing in order to correct the said tilt angle. The processed image data area stored again in the memory 34. When a user performs the rotation processing at his/her desired angle, this angle is inputted by means of a rotation angle setting ten-key 30a of an operation part 30. Thus, inputted angle is stored in a tilt angle memory 38.  Then the means 36 applies the rotation processing to the image data of the memory 34 according to the set angle of rotation that is stored in the memory 38.

Title: Drive controller for wire dot-type printing head
Inventor: UEDA MICHIO
IPC: B41J2/51
Filed: 1991-07-22
Abstract: PURPOSE:To prevent laterally continuous 2 dots from becoming 1.5 times as thick as those printed at a normal speed when the total number of printing dots is required to be reduced to approximately 2/3 when printing is conducted at a speed 1.5 times a normal speed. CONSTITUTION:When printing is conducted at a speed 1.5 times higher, dot data is developed by a doubling developer 80 so as to be doubled in a lateral direction. After that, a comparator 84 controls the forming of dots so that a dot printed in a previous printing and a further previous printing cannot be formed. At this time, when original printing data of laterally continuous 2 dots is printed at a speed 1.5 times higher, 2 dots are also printed at an interval 1.5 times larger than that in a normal printing (a normal speed). In a conventional method, in the forming of continuous dots, the printing timing of the second or succeeding dot is delayed so as to be shifted rearward. However, in this device, with respect to a dot judged by a history judging part 100 as the last in continuous dots, the printing timing of the last dot is not delayed.

Abstract: PURPOSE:To improve data transferring function and transferring efficiency by providing in a control device a measuring signal sending means to a measuring signal line, a measuring signal detecting means, a measuring means to measure a time from the sending of a measuring signal to the detecting of the signal and a means to set the period of a transmitting signal according to this measured value. CONSTITUTION:When the power source of a control device 20 is turned on, a measuring circuit 2 causes a timer 1 to be enable by a signal line 103 and sends the measuring signal to a signal line 101 simultaneously. The measuring signal passes through a measuring signal line 100 and it is detected from a signal line 102 through a receiver 5 by the measuring circuit 2. The measuring circuit 2 to detect the measuring signal stops the timer 1 by the signal line 103 and instructs the setting of a transferring speed to a transferring clock generating circuit 3 by a signal line 104. The value of the timer 1 at such a time is determined by the lengths of input and output interface cables 201 and 202. The transferring clock generating circuit 3, to which the setting of the transferring speed is instructed, sets the maximum data transferring speed to be transferable by the value of the timer 1 and hereafter, the data transferring can be executed at the set speed.

Title: Radiation measuring device
Inventor: ISHIBASHI MITSUO
IPC: G01T1/167
Filed: 1981-12-19
Abstract: PURPOSE:To improve measurement sensitivity without decreasing the moving speed of a sample of measurement by using plural radiation detectors. CONSTITUTION:Radiation from a moving sample 11 of measurement is detected by plural, e.g. two radiation detectors 12 and 13, whose detection pulses are processed by integrating circuits 18 and 19, an adding circuit 20, etc., controlled through waveform shaping circuits 16 and 17, and a timer 21 to measure the radiation. In this case, since two detectors 12 and 13 are used, integration time T is twice as long as when only one detector is used on condition that the sample speed is unchanged, thereby increasing the sensitivity by 2<1/2> times on the basis of an equation. Thus, the measurement sensitivity is improved without reducing the moving speed of the sample of measurement.
