Title: Laser marking method
Inventor: FUJISAWA MASAAKI
IPC: G02B27/00
Filed: 1988-02-23
Abstract: PURPOSE:To enable arbitrary color marking to be conducted on a surface of a transparent body, by bringing the surface of the transparent body into contact with a coated surface of a substrate, and irradiating the coated surface with predetermined laser light in a desired pattern. CONSTITUTION:A flat surface 10a of a substrate 10 is coated with a coating material having a desired color in a considerable thickness to provide a coated surface. A surface 12a of a transparent glass plate 12 to be marked is placed on the coated surface. A convex lens 14 and a mask 16 are disposed directly above the glass plate, the mask being provided with a desired pattern. When YAG laser light LA consisting of parallel rays is projected on the mask from above, the laser light transmitted through the mask pattern is condensed by the lens, passes through the glass plate, and forms an image on the coated surface of the substrate. A coating material PA of the coated surface is instantaneously melted by the laser energy, and comes off from the substrate 10. Since the part of the melted coating material is hermetically sealed, the melted coating material is not evaporated but is adhered to the surface of the glass plate. The pattern of the part thus transferred corresponds to the mask pattern.

IPC: B65H3/52
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of static electricity due to the friction at the time of feeding paper sheets and the charge with electricity to the paper sheets while keeping a high frictional force necessary for feeding paper sheets by making up the feeding paper members both with polymeric materials having a volume specific resistance of a specific value or more and with conductive materials, and by making the entire volume specific resistance to be less than a specific value. SOLUTION: The device is provided with a feed roller 3 for rotatedly feeding a paper sheet 1 in the feeding direction, a reverse roller 4 for turning the sheet in the direction reverse to the feeding direction that has been provided so as to sandwich the passage of the paper sheet 1, and a pickup roller 2 for feeding the uppermost paper sheet of the stacked paper sheets 1. To at least one of these rollers 2 to 4, a paper feeding member consisting of polymeric materials having a volume specific resistance of 10<10> Ω.cm or more and conductive materials is used. The volume specific resistance of the paper feeding member is preferably 10<9> Ω.cm or less, and further preferably 10<8> Ω.cm or less, and furthermore preferably 10<7> Ω.cm or less.  Thus, the image contamination of electrophotography can be prevented without generating static electricity for charging this to the paper sheets.

Title: Character/pattern recognizer
Inventor: FUJII HISATAKA
IPC: G06F3/042
Filed: 1984-03-02
Abstract: PURPOSE:To enable a recognizer regardless of large character sizes by detecting a vector indicating respective line directions of written characters and depicted patterns, and by comparing this vector with data for characters and patterns prepared as data. CONSTITUTION:An inputted light coming in from an optical fiber 3 is distributed by a light distributor 10 into two directions; one light is inputted to a photoelectric converter circuit 11 which uses a phototransistor and outputted as an analog signal. The analog signal is divided into three steps by a comparator 12 and outputted as a digital signal to a computer. The other light enters a light spectroscope 13 to be resolved into primary colors; red, blue, and green, which enter respective photoelectric converter circuits 14R, 14G, and 14B. The light input is any one of these three colors; red, blue, and green, therefore one of the three photoelectric converter circuits is entered by the light input and is outputted as the digital signal. The signal from the comparator 12 indicates right/left directional pen's movement and the one from said circuit upper/lower directional pen's movement, thereby enabling the computer to calculate from the signals and to recognize characters and patterns.

IPC: B65H3/06
Filed: 1992-02-27
Abstract: PURPOSE:To prevent an improper feed of paper from being induced by changing a contact part of a take-in roller so as to maintain frictional force. CONSTITUTION:Right/left rotary knobs 14a, 14b are turned in a reverse direction to each other to rotate supporting shafts 8a, 8b in a reverse direction to each other. Here by fitting the supporting shafts 8a, 8b to flanges 5a, 5b rotatably and unmovably in the axial direction, press rollers 7a, 7b are moved not to rotate while pressing an internal surface of a cylinder 4 and coming near to or separating from each other in the axial direction. In this way, a position of pressing the cylinder 4 by the press rollers 7a, 7b is changed to form external appearance of the rubber-made cylinder 4 changed from a drum shape to a reverse drum shape. Consequently, a contact part of the cylinder 4 with paper can be changed from a surface part of decreasing frictional force by paper powder, stain, etc., to a surface part having the initial frictional force.

Consequently, current flows between a land 18 and a circuit 11 and a land 19 and the common electrode plate 15 through a bar-shaped resistor 14 via a through hole 12. The current is measured with a resistance decision section 6 and compared with values of respecting circuits 11 prememorized into a control section 5 to determine the propriety of the circuits 11. According to this method, the condition of the wiring can be detected simply by  measuring combined resistance values with only one probe.

Abstract: PURPOSE: To accurately measure the fine change in optical absorptivity to improve the process rate by uisng a photometer and a A/D converter of about 16 bits.  
     CONSTITUTION: To a detector 11, there are consecutively connected an A/D converter 12 of 16 bits (of binary type), an integrating substitution circuit 13, a subtracting and dividing circuit 14, an integrating circuit 15 and an output circuit 16. Thus, the signals detected by the detector 11 are converted into digital signals. Then, n number of data Tx of transmissivity are bundled by m number and are  converted into (n-m) number of digital data. After that, the differences between the adjacent data are calculated and are divided by the respective data. The resultant values are integrated to obtain the change in optical absorptivity, which is fed to the output circuit so that it is displayed as an analyzed value. As a result, the resolution is improved to 1/m thereby to enhance the overall stability and resolution so that the rate measurements at a high speed under a high dilution condition can be made.

Abstract: PURPOSE:To automatically set the channel type of primary speed interface in an ISDN service. CONSTITUTION:According to the primary group velocity interface channel type (1.5MCT) of a terminal 1 to be connected, a processor 13 of an exchange 10 outputs a command setting on-display '1' to the specivic bit of a layer 1 control signal (CO) for a signal device 11. When the signal device 11 accepts this command, it sets '1' to the specific bit for CO. A 1.5MCT 5 accepts the CO from the signal device 11 by a control section 14 and identifies it. A switch section 15 switches the channel to the channel D or to the channel B when the specific bit of the CO is '1'. To inform the processor 13 that the changeover is normally performed by the control section 14, '1' is set to the specific bit by using a monitoring signal (ST) of the level system on a control channel. The signal device 11 notifies it to the processor 13.
