Filed: 1987-02-25
Abstract: PURPOSE:To obtain a color image forming device which is small-sized operates at a high speed and decreases color slippage by energizing two pieces of writing means successively and forming an image on sheet paper wound on a drum, thereby forming the image thereon. CONSTITUTION:A copying machine 120 is constituted of a color image reader 121 and a color image printer 122. The machine is constituted that the 2nd writing means is energized with a prescribed time lag after the 1st writing means for forming the monochromatic color image is energized. Two kinds of the color images (for example, yellow and magenta images) are, therefore, successively formed first from the two writing means at the time of rotating a rotating members one turn, and the remaining color images (for example, cyan and black images) are formed by the next rotation at the time of forming the color image. The desired color image is thereby formed without considerably decreasing the image forming speed while satisfactory registration is maintained.

Title: Signal amplitude converting circuit
Inventor: KITSUKAWA GOROU
IPC: H03K19/018
Filed: 1984-03-02
Abstract: PURPOSE:To attain high performance LSI by adding a level shift diode between a collector of a bipolar transistor (TR) and a gate of an n-MOS FET so as to obtain a large output amplitude. CONSTITUTION:The basic building block is improved; a diode D3 is provided between a collector of a bipolar TRQ3 and a gate of an n-MOS FET Q2 and an R3 is added. When an input VIN is at a low level, both the Q3, D3 are turned off, 0V is applied to the gate voltage of the Q2 via the R3 and the Q2 is turned on. When the VIN goes to a high level, the TRQ3 is turned on and the collector current flows not only to the R1 but also to the R3 and D3. A voltage higher than a Vout 2 by a VBE is applied to the gate of the Q2, the ON-resistance of the Q2 is increased by the voltage so as to prevent the saturation of the Q3. As a result, the low level of the Vout 2 is as expressed in equation and a 3.6V output amplitude is obtained. An amplitude larger than the Vout by 0.8V is obtained in this way.

Title: Method for measuring three-dimensional free curved surface and probe device
Inventor: SHINOHARA YOSHITO
IPC: G01B21/00
Filed: 1982-03-18
Abstract: PURPOSE:To obtain a device which measures three-dimensional free curved surfaces, by using  a probe of optional shapes. CONSTITUTION:A contact ball 2 which is in contact with an origin ball 1 is directly coupled to  a spherical probe 4 with a shaft 3 for transmitting displacement. The shaft 3 is supported by  means of a three-dimensional parallel moving mechanism. To measure the coordinates of the  3rd axis where the 1st axis and the 2nd axis are fixed, the ball 1 is driven from the direction  of the 3rd axis and the probe 4 is brought close to a measuring surface 5; further, when the  ball 2 is driven clockwise while held in contact with the ball 1, the probe 4 contacts the points  P1, P2 of the surface 5. Thereupon, the ball 2 is stopped at the intermediate points of the two  displacing coordinates within the planes of the 1st axis and 2nd axis viewed from the direction  of the 3rd axis of the ball 2 when the probe 4 contacts the points P1, P2. Again, the ball 1 is  driven finely from the direction of the 3rd axis and when the ball is successively centered from  the intermediate point to the intermediate point by repeating the above-described operations,  the limits of the points P1, P2 converge successively at one point, and the centering of the contact point of the probe 4 to the true measuring point is completed. Even if a probe 7 of an optional shape is used, the similar effect is obtd. by using a moving function cam 8 which corrects and eliminates the influence of said optional shape.
