Title: Diode element
Inventor: SHICHIRI NORISHIGE
IPC: H01L31/10
Filed: 1989-11-27
Abstract: PURPOSE:To obtain an excellent rectification characteristic and to prevent a change in performance even when a diode is left in the air for a long time by a method wherein the diode is formed by laminating the following: an organic conductive thin film obtained by plasma-polymerizing a condensed aromatic ring and/or its derivative; and an organic semiconductor. CONSTITUTION:As a condensed aromatic ring and its derivative, 3,4,9,10-perylene tetracarboxylic acid dianhydride expressed by formula I and 3,4,9,10-perylene tetracarboxylic acid diimide and its derivative expressed by formula II are used. Since the condensed aromatic ring and its derivative are solid at room temperature and normal pressure, a plasma polymerization method is used for their polymerization. As an organic semiconductor which is laminated on them, a sublimating pigment such as phthalocyanine, Malchite Green, rose bengal or the like is used; a substrate which has a smooth face may be used as a substrate; a glass, a metal, a plastic or the like is used. That is to say, since the organic semiconductor is conductive without being doped, a change in a rectification characteristic is not caused with the passage of time.

Title: Nonvolatile semiconductor memory
Inventor: NOJIRI ISAO
IPC: H01L29/788
Filed: 1988-12-06
Abstract: PURPOSE:To lighten the excessive stress to memory cells and increase the reliability by lessening the voltage value of high-voltage pulses applied at the time of erase or write. CONSTITUTION:Two transistors 29, 30 are added to a charge pump circuit. At the time of erase or write, these two transistors 29, 30 shift high-voltage pulses to the voltage value at the time the threshold value of nonvolatile memory transistors saturates. At least at one time out of applied high-voltage pulse write or erase time like this, the threshold voltage of the nonvolatile memory transistors which changes when high-voltage pulses are applied is made to have such a degree of voltage value that it is saturated by the applied high- voltage pulses. This lessens the excessive stress to memory cells and increases the reliability without the nonvolatile memory transistors spoiling the stable memory-holding state.

Title: Noncontact method for measuring three-dimensional micro structure using optical window
Inventor: HII JE BAKU
IPC: G06T7/00
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To enable highly accurate measurement, by obtaining a relationship of a size ratio of a well-defined image and a blurred image formed on a screen and a relative height difference of a reference position and a position other than the reference position, and repeatedly obtaining the relative height difference for all of a surface after moving a measurement object, respectively. SOLUTION: A slit light shed onto a measurement object 1 is reflected by the measurement object 1, passing through an objective lens 18 again to be focused on a screen 20. The screen 20 is moved towards the objective lens 18, so that a blurred image and a reference surface present at a position of a lowest height which is certainly in focus among many surfaces are positioned on the screen 20. A size of an image formed on the screen 20 at a reference position is measured. A predetermined count of size ratio data of the blurred image to an image at a place other than the focused reference position is obtained. The screen is moved so that a focus is met at a place other than the reference position, and a relative height difference is obtained. A formula representing the relationship between the size ratio and relative height difference of images is obtained.  The relative height difference is calculated for all of a surface of a minute gap of the measurement object.

Title: Error adjusting method for plate bending machine
Inventor: MOMOKITA ATSUSHI
IPC: G05B19/404
Filed: 1991-10-28
Abstract: PURPOSE:To obtain a high quality bending product by allocating the plate error to a part in which an error is allowed, without prolonging the cycle time. CONSTITUTION:This method is applied to a plate bending machine for bending the part protruded from an inserting and holding mold 3a of a plate W by a bending mold 3b by feeding the plate W between the inserting and holding molds 3a. At the time of adjustment, by an input screen 40 for generating a working program 36 by an automatic programming device 39, it is inputted in advance to discriminate whether it is the part in which an error is allowed or not. This allowed/unallowed data 45 is added to a feed command 44 of a plate in the working program 36, and when working is started by executing the working program 36, plate width is measured actually and errors DELTAX, DELTAY to plate width input data are calculated. This error arithmetic value is allocated to the feed command 44 having data of an error allowance 'allowed', and a feed amount command value is offset. By executing working in such a way, an error can be taken to the part in which an error is allowed without varying the working order.

Title: Headlamp for small vehicle
Inventor: SHIOTANI TOSHIYUKI
IPC: F21V5/00
Filed: 1989-11-29
Abstract: PURPOSE:To prevent rain water adhering on the lens surface of a headlamp from entering inside the handle bar cover and make the lens surface less likely to collect dust by directing the lens surface obliquely downward. CONSTITUTION:The lens 38 is provided with lens cutting so that the forward illuminating performance is not lowered. Since the lens surface 38a is directed obliquely downward, the rain water adhering on the lens surface 38a is less likely to enter the gap 40 between the lens 38 and a handle bar cover opening 33. Therefore, the rain water prevention structure within the cover is made simpler. Dust is less likely to collect on the lens surface 38a when it is left outdoors.

Inventor: NAKANO HARUO
IPC: H04B3/46
Filed: 1990-11-15
Abstract: PURPOSE:To simply recover a communication disable state due to a broken wire by using a switch means to replace a broken twisted pair wire with a backup use twisted pair wire when the 2-pair twisted pair wire used for usual transmission reception is broken. CONSTITUTION:Four-pairs of twisted pair wires 3 include two pairs of twisted pair wire 3a used for usual transmission reception and two pairs of twisted pair wires 3b for backup use. When the pair wire 3a is broken at a location marked X, since a reception monitor circuit 43 cannot receive both a link test pulse signal and a data signal, a communication disable circuit 45 implements display and the location of the broken wire is clarified. In this case, a switch means SW is switched to use the twisted pair wire 3b to recover the system easily from the communication disable state due to the broken wire.

Title: Solid-state image pickup device
Inventor: MOCHIZUKI SATORU
IPC: H04N5/357
Filed: 1987-12-07
Abstract: PURPOSE:To solve interference fringes by the reflection of light by using a transparent adhesive having larger refractive index than a color filter and having a thickness more than a value that the square of the wavelength of the used light is divided by the refractive index between the light-receiving face of an image pickup element and the color filter. CONSTITUTION:The refractive index of the transparent adhesive 4 used between the color filter 5 and a solid-state image pickup element 2 is selected larger than that of the color filter 5 and the thickness of this transparent adhesive 4 is made into the thickness more than the value that the square of the wavelength of the used light is divided by the refractive index. That is to say, an optical path difference in which the interference fringes are not generated is shortened by the value divided by the refractive index and as the use quantity of the transparent adhesive 4 is decreased, the quantity of the light entering by losing its way among the rays of light entering an adjacent image element can be decreased. Thus, the generated interference fringes in the image can be solved.
