Title: Pyroelectric recording and reproducing system
Inventor: MURANO KANJI
IPC: G11B9/00
Filed: 1986-08-14
Abstract: PURPOSE:To improve recording and reproducing characteristics by selectively irradiating the 2nd electrode formed of a photoconductor, functioning only the irradiated region as an electrode, and functioning a non-irradiated region as an insulating region, thereby dividing the electrodes. CONSTITUTION:A prescribed voltage is impressed to a 1st electrode 3 and taking out region 5 of a recording medium 1 at the time of recording an information signal to a pyroelectric material layer 2. The prescribed region of the 2nd electrode 4 is selectively irradiated by using a light projecting means; the light from a light source 11 is collimated to parallel luminous fluxes by a collimator lens 12 at this time and the light is selectively projected across the 2nd electrode 4 and the region 5 by a cylindrical lens 13. The region A irradiated with the light, therefore, functions as the substantially divided electrode and the region of the 2nd electrode 4 which is not irradiated by the cylindrical lens 13 functions as the mere insulating region. The recording and reproducing characteristics such as high speed writing, high speed reading out and increase of the current of a reading out signal to large current are improved by such division of the electrodes by the projection of the light.

Title: Method and system for ion implanting of low dosage amount
Inventor: GWINN MATTHEW CHARLES
IPC: C23C14/48
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for implanting ions at low dosage, while enabling accurate and stable control. SOLUTION: This ion implantation system is constituted of an ion source 12 for ionizing a diluent, i.e., a rare gas, and a specified dopant gas an implanting the ions into a substrate S. Since the rare gas does not react with the dopant gas not with the residue of dopant covering the inner wall of an ion chamber 24, ions can be implanted accurately and stably at a low dosage. Furthermore, since the rare gas does not introduce ions or impurities which cause fluctuations of conductivity into the substrate, dosage of dopant ions being implanted into the substrate S is controlled accurately, especially when a low dosage is applied.

Therefore, the slippage between the rolled material 1 and the repeater floor 13 is eliminated, and since the rolled material is conveyed without sliding on the conveying rollers 2, the generation of the scratch flaw is remarkably reduced. Further, if necessary, the same conveying rollers are arranged to the side looper, too, and thus, the generation of the scratch flaw is further reduced.

Title: Detection of convergence error for projection type display
Inventor: KANAZAWA MASARU
IPC: G09F9/00
Filed: 1987-07-31
Abstract: PURPOSE: To easily detect a convergence error by burying a photosensor in a reflection mirror face which is provided in an enclosure and is not an image forming face and using a video signal which forms a simple pattern on a screen. CONSTITUTION: Emitted light from a projection device 1 including R, G, and B projectors is reflected by mirrors 2 and 3 and is made incident on a screen 4, and a part of this light is made incident also on a photosensor 5 on the surface of the mirror 3 which is not an image forming face. Two white window signals 7A and 7B are used as the video signal and are periodically switched. That is, the state for light incidence is taken as a reference state to find which positional relation the photosensor 5 and white window signals have although two white window signals are switched. When the positional relation between the screen 4 and the mirror 3 is fixed, that between the photosensor 5 and the screen 4 is not varied; and therefore, the positional relation on the screen of white window signals is found by switching two white window signals.  Since the positional relation of each color corresponds to convergence, the convergence error is detected.

Abstract: PURPOSE:To improve the efficiency of access to buffer storage by transferring data requested by recognition means from a buffer storage or a transfer buffer. CONSTITUTION:When data is transferred from a main memory device 1, it is held at a transfer buffer 31. A selection circuit 33 sequentially selects the 8 bytes to be transferred, and transfers them to a buffer storage 22. During this transfer, transfer bit is registered as '1'. And when the transfer of block unit is completed, '0' is registered for transfer bit, and '1' for effective bit. The address to be accessed from a request origin to the main memory device 1 is inputted to an address register 34. And, a comparator 35 examines whether or on which page of table such address does exist according to information of 0-26 bits of address register 34. If such address does not exist, then transfer is made from the main memory device. If it exists, a control part 36 sends it to the request origin according to the condition of effective bit and transfer bit.
