Patent JP-H04128718-A (JP)
Title: Optical coupler
Inventor: NAGANUMA NORIHISA
IPC: H01S3/06
Filed: 1990-09-20
Abstract: PURPOSE:To realize low loss, high stability, decrease in the number of components, and size reduction by constituting the optical coupler by interposing a non-reciprocal means between a multiplexer and a lens of at least one stage. CONSTITUTION:The non-reciprocal means (optical isolator) 26 is interposed between the multiplexer 23 and lens 27 of at least one stage. Namely, the non- reciprocal part 26 is interposed between the multiplexer 23 and converging lens 27, so reflected feedback light which returns to the multiplexer 23 from the side of an Er-doped fiber 28 is cut off by the non-reciprocal part 26 to prevent a noise from being generated by an optical fiber amplifier and optical amplification from becoming unstable owing to resonance. Nonreflection processing is done for a fiber end and a lens on the output side of the non- reciprocal part 26 and may be done even for a fiber end and a lens on the input side when necessary. Consequently, the optical fiber amplifier is reduced in loss and made highly stable and the number of components is decreased to reduce the size.

Title: Synchronous addition system color linear sensor
Inventor: KAWAMOTO SEIICHI
IPC: H04N1/028
Filed: 1992-08-24
Abstract: PURPOSE:To prevent moire by shifting color filter arrays from one another between adjacent sensor arrays. CONSTITUTION:Respective sensors of color filters 11, 12, and 13 and shift gates 2 between color filters are obliquely formed, and color filter arrays are shifted from one another between sensor arrays so that color filter arrays are shifted from each other by the extent of unit combination (R, G, and B) of color filters between sensors which pick up the same point of the filter 11 of the first stage and the filter 13 of the third stage. Since subscanning passes all of color filters R, G, and B in the process of subscanning from the filter 11 to the filter 13 when one point is noticed, all color components are detected by three sensor arrays 11 to 13. Thus, the occurrence of moire is prevented.

Title: Method of controlling injection of injection molding machine
Inventor: TANIGUCHI YOSHIYA
IPC: B29C45/52
Filed: 1988-10-04
Abstract: PURPOSE:To manufacture a stabilized molded product by maintaining a fixed quantity of injection resin always without having a variation in a measuring quantity of the resin even if a suck back action is performed, by a method wherein resin pressure at the rear side of a check ring is made more negative pressure than that at the front side of the check ring by reversing a screw. CONSTITUTION:A screw 2 is turned by fixed seconds in the reverse direction prior to breaking of a mold after completion of kneading/plasticization/ measuring strokes. With this construction, resin pressure of molten resin 3 which is on a rear side of a check ring 5 is lightened and the same becomes more negative pressure than the molten resin 3 stored at the tip side of a check head 4 by measuring. consequently, an end face 5a of a circular annulus of the check ring 5 is stuck to a check sheet 6 and the molten resin 3 stored at the tip end side of the check head is prevented from flowing backward. Then the screw 2 is moved backward and the resin pressure of the molten resin stored on the tip side of the check head 4 is decompressed by a fixed value. At the time of what is called suck back stroke, a quantity of the resin stored at the tip side of the check head 4 by measurement is kept fixed.

Title: Image recording device
Inventor: ASANO KAZUO
IPC: G03G15/08
Filed: 1996-08-31
Abstract: PROBLEM TO BE SOLVED: To improve the transfer efficiency from an image carrier to a recording sheet or an intermediate transfer body, and stably perform a satisfactory image recording without being influenced by an environmental fluctuation by applying a powder having a particle size smaller than toner on the surface of the image carrier and substantially uniformly adhering the fine particles thereto. SOLUTION: A magnetic brush of carrier is formed on the surface of a fine particle imparting roll 4a possessed by a fine particle imparting means 4 by the magnetic force of a magnet roll, and the fine particle of a powder is adhered to the carrier. The magnetic brush makes contact with an image carrier 1, whereby the fine particle of the powder is adhered and substantially uniformly applied to the surface of the image carrier 1. Since the powder fine particle having a particle size smaller than toner is thus substantially uniformly adhered to the surface of the image carrier 1, and a toner image is formed on the fine powder, the adhesion between the toner particle and the image carrier 1 is reduced. The toner particle is easily transferred when an electric field acts thereon in transfer, and the transfer efficiency is thus improved.

Title: Road display detection system
Inventor: SUDA TOSHIHIKO
IPC: G06K7/14
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To make a road display detection system useful for safety drive by making the road signs of a highway and a general road readable with a sensor. SOLUTION: Bar-like digital road signs (4, 5 and 41, for instance) are provided on the road surface or side wall surface of a highway and general road. By the length of a bar, the length of the interval of the bars, the thickness of the parallel bars and the width of the interval of the parallel bars, etc., bar-like display indicates '1' and '0'. The digital road signs are read from a vehicle during traveling by a camera sensor and the information of the road signs is reported to a driver in real time by a monitor or a speaker inside the vehicle. Since the need of viewing the road signs is eliminated, the driver can devote himself/herself to drive. For the bar-like digital road signs, since just white lines are drawn on the road surface, the digital road signs can be formed on the road surface without providing special equipment.

Title: Method for evacuating evaporation device
Inventor: KAI YUKIHIRO
IPC: C23C14/24
Filed: 1985-11-06
Abstract: PURPOSE:To shorten evacuation time of a vacuum vessel utilizing getter effect of evaporated metal by providing a body to be previously evaporated in the vacuum vessel separately and subjecting the body to previous evaporation treatment with metal to be evaporated. CONSTITUTION:A bell jar 1 is evacuated with a vacuum pump 2 after holding a material 5 to be subjected to evaporation treatment at a predetermined position in the bell jar 1. Before the degree of vacuum in the bell jar 1 reaches a target value by the evacuation, the upper part of an evaporation boat 3 is covered with a shutter 6 (a body to be previously coated by evaporation), and a fixed amt. of metal 4 to be evaporated (Al) is evaporated. A major portion of the evaporated Al 4 is deposited on the shutter 6 without depositing on the aimed body 5 for evaporation, and a part of the evaporated Al reaches the inside wall of the bell jar 1. The evacuation of the bell jar 1 is prompted by the getter effect of the evaporated Al 4 and the evacuation time is shortened. When the degree of vacuum reaches the target value, the cover of the boat is removed by moving the shutter 6, and the aimed body 5 for the evaporation is treated with the usual evaporation process.

Abstract: PURPOSE:To perform speech with a doorphone only by performing the off-hook operation of a general telephone set by forming a speech path between a telephone set and the doorphone via a change-over switch part when an off-hook signal exists after on-hook is performed once. CONSTITUTION:When the telephone set is off-hooked, an off-hook detection signal from an off-hook detection circuit 8 is inputted to a control circuit 11, and the circuit 11 forms the speech path between line wires L1, L2 and the telephone set with the change-over switch part 7, which enables line wire call issuance to be performed. Also, when incoming signals are inputted from the line wires L1, L2, the bell of the telephone set connected to an extension via the switch part 7, etc., is rung, which enables line wire speech to be performed. When a call is placed from the doorphone D during performing the line wire speech and a doorphone call detection circuit 12 detects it, the circuit 11 performs call information with a melody output circuit 17. When a user performs the off-hook of the telephone set again after performing the on-hook once replying to the above operation, a signal is sent from the circuit 8 to the circuit 11, and the speech path between the telephone set and the door-phone D can be formed with the switch part 7, thereby, speech between the doorphone D and the telephone set can be performed.
