Title: Ageing of cathode-ray tube
Inventor: IMANISHI WATARU
IPC: H01J9/44
Filed: 1981-06-18
Abstract: PURPOSE:To prevent any beam current sent form a cathode form flowing onto the extreme end of a cecond grid by applying a negative voltage of -800- -3,000V to an anode during the ageing process of a cathode-ray tube. CONSTITUTION:When a negative voltage of -800--3,000v is applied to an anode 5, and a voltage of 70V is applied to a second grid 6 during the ageing process of a catode-ray tube, the flow lines of a beam current 19 developing from a cathode 8 become as indicated in the figure. Since a highly negative voltage is applied to the anode 5, and the aperture of the grid 6 on the anode 5 side is large, an electric field developing from the anode 5 enters inside the grid 6 so as to deflect the beam current 19. As the result, the current 19 is prevented from flowing onto an ectreme end 61 of the grid 6. Consequently, any activation of an oxidized getter film adhering to the end 61 of the grid 6 is prevented, and any defective straight emission generated during the ageing process can be completely prevented.

Filed: 1978-08-04
Abstract: PURPOSE: To facilitate space adjustment between two ajoining letters thus providing high effectiveness by projecting a letter next to a hard-copied letter on a recording paper, and by confirming the space directly with one's eyes.  
     CONSTITUTION: An optical image from a printing optical system is reflected by a mirror 4 and is transferred to a halfmirror 21 through an image rotating prism 19 and an image forming lens 20. There, the light path is divided into two: one goes to an image picturing system where the optical image of a letter is shotoelectrically converted, while the other goes directly to a projecting system. In the image picturing system, the image of the letter is formed on an image forming plate 23 through a mirror 22, and is projected on an one-line image sensor 25 through an image contracting lens 24. This optical signal is converted into photoelectricity and is synchronized with motion of a scanning block 21 and 22, then is stored as a letter data in a memory. While in the projecting system, the image of the letter is formed through the mirror 21 on a recording paper 26, then is compared with a hard-copied letter for spacing.

Title: Dynamic semiconductor memory device
Inventor: MITSUMOTO TOSHIO
IPC: G11C11/34
Filed: 1984-05-12
Abstract: PURPOSE:To make a difference voltage applied to a sensor amplifier larger and to increase an action margin by connecting one terminal of a storage accumulation capacity to one end of a complementary bit line and the other terminal to the other end of said line through a selection means. CONSTITUTION:When a selection signal having larger voltage than a power supply voltage VCC to a word line Wi; a memory cell 11, etc., are selected through a transfer gate 13 connected to one bit line 1 of complementary bit lines. When a power supply potential VDD and grounding potential are applied to the bit line 1 and a bit line 2, respectively, a node 14 of a storage accumulation capacity 12 between the gate 13 and the bit line 2 goes to the potential VDD. Then, when the line Wi is dropped to a load potential to cause the gate 13 to be cut off, and the bit lines 1 and 2 are precharged to the potential VCC, the potential of the node 14 rises to that twice the potential VDD, and an information 1 is written at a high potential level. As a result, a difference voltage supplied to a sensor amplifier S at the time of reading becomes larger, and an action margin of a dynamic semiconductor memory device can be improved.

Title: Optical semiconductor integrated circuit
Inventor: TAKAHASHI TSUYOSHI
IPC: H01L27/15
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To prevent optical carriers generated in separation areas from disappearing and the output of photodiodes from deteriorating when the width of the separation areas surrounding the photodiodes is large in an optical semiconductor integrated circuit for forming the photodiodes of two rows and two columns, irradiating the photodiodes with optical spots and detecting dislocation. SOLUTION: In a second epitaxial layer 23, the upper diffusion of second separation areas 26 is set so that it exceeds the half of the thickness of the epitaxial layer 23 and the width of a third separation area is shortened. Thus, the extinction of the optical carriers is suppressed. In a first epitaxial layer, first separation areas 25 are set so that they exceed the half of the epitaxial layer 21. When the second separation areas 26 overlapped with the areas 25 are set so that they exceed the half of the thickness of the second epitaxial layer 23, the width of the second and the third separation areas 26 and 27 can be shortened and the extinction of the optical carriers can be prevented.

IPC: G03G15/08
Filed: 1990-04-13
Abstract: PURPOSE:To surely supply a developer from a developer replenishing unit to a body to be replenished by making the force required for opening a slide type opening/closing cover larger than that required for sliding a developer replenishing container on a replenishing body. CONSTITUTION:As long as the force F2 is not larger than the force F1 for sliding the developer replenishing container 20 on the placing part 13 of a con tainer attaching part 11, the opening/closing cover 23 is not opened while sliding it. Therefore, the developer replenishing container 20 is dropped into the placing part 13 of the container attaching part 11 of a hopper top cover 10. In the forward slide-movement of the container 20, even if its moving amount is not enough, and the developer replenishing container 20 is not correctly positioned on the container attaching part 11, the developer replenishing container 20 is slid and correctly positioned on the container attaching part 11 by the force to open the opening/closing cover 23, and then, it is opened. Thus, the developer can be surely supplied inside the body to be replenished.
