Abstract: PURPOSE:To eliminate the need for the projection of a hook switch operating part on a telephone set case body by detecting information outputted from one or plural sensors of a pressure sensor group distributed on the telephone set case body, sending a control signal and opening and closing an electron contact by means of the control signal. CONSTITUTION:When a handset 1 is placed on a case body 2, sensors 31-m and 41-n sense the load of the handset 1, and information pieces a1-an and b1-bn are sent to a signal processing circuit 5. The signal processing circuit 5 processes such data, decides whether the handset 1 is placed on the case body 2 or not, sends a control signal (c), operates an electron contact 6, and makes an on-hook condition. To the contrary, when the handset 1 is lifted up from the case body 2, the sensors 31-3n and 41-4n stop outputs of the information pieces a1-an and b1-bn, the signal processing circuit 5 sends a control signal c', the electron contact 6 is operated, and an off-hook condition is made. Thus, the projection of the operating part of the hook switch can be made unnecessary.

Title: Optical multiplexer/demultiplexer
Inventor: NAKAZAWA MASATAKA
IPC: G02B6/12
Filed: 1989-12-08
Abstract: PURPOSE:To obtain low-loss and low-crosstalk characteristics by adding a rare earth element having the absorptive and fluorescent characteristic to one wavelength into the cores of directional couplers and propagating the exciting light to amplify the light signal of the wavelength from the output side. CONSTITUTION:The directional couplers 8, 9 are used as the circuit to demultiplex the light signals of the two wavelengths lambda1 and lambda2. The rare earth element exhibiting the absorptive and fluorescent characteristic to lambda1 is added into the cores 31 to 35 which are the parts where the light is propagated of the directional couplers 8, 9. The exciting light 7 for amplifying the light signal of lambda1 is propagated from the outside side where the light signal of lambda1 is demultiplexed, by which the light signal of lambda1 is amplified. On the other hand, the light signal of the non-desired light lambda1 leaking into the output side where the light signal of lambda2 is demultiplexed is absorbed by the rare earth element and is thereby decreased. Thus, the low-loss and low-crosstalk characteristics are attained.

Abstract: PURPOSE: To provide an image processing device and a method which is excellent in the respective aspects of speed, a grade and also a memory quantity by properly switching a part to extract its contour vector data and a nonextractive part according to a given binary image. CONSTITUTION: Whether an inputted binary image is in a character-line drawing area or a pseudo-intermediate tone image area is roughly judged by an area judging part 1-4 by using a prescribed quantity as a unit. A character-line drawing area expanding extracting part 1-7 outpus only image data judged as a character-line drawing area, and a contour vector extracting part 1-11 takes in it, and outputs contour vector data to an accumulating part 1-13. Though a first smoothing part 1-14 smooths vector data accumulated in this accumulating part 1-13, a monitoring part 1-19 monitors a quantity of data accumulated in the accumulating part 1-13.  When the fact that the vector data is too many to a certain image quantity and oveflows is judged, vector smoothing processing to an area of interest is interrupted, and instruction is given to an internal processing control part 1-20 so as to select the binary image by a binary SPC part 1-21.

Abstract: PURPOSE:To prevent etching residue of a metal wiring film on the side surface part of an interlayer insulating film, and prevent the generation of cracks in the interlayer insulating film occurring by impulsive force at the time of bonding, by forming a ring type part separated from a bonding pad part. CONSTITUTION:On a first metal wiring film, a first layer insulating film 3 is formed, and thereon a second metal wiring film 6 is formed wherein a gold- plated film 5 is formed by using a power supplying film 4. An aperture 8 is formed in a second interlayer insulating film 7 which is formed on the film 6 by coating. In the aperture 8, a bonding pad 11a is formed by using a third metal wiring 11 composed of a power supplying film 9 and a gold-plate film 10. At the same time, a ring type part 11b is formed so as to cover the side surface part 8a of the aperture 8 by using a part of the third metal wiring layer 11. Since the bonding pad part 11a is formed only in the inside of the aperture 8 in this manner, the force at the time of bonding is not applied to the second interlayer insulating film 7, and the generation of cracks in the second interlayer insulating film 7 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To measure the system margin of a two-way transmission/reception circuit with simple constitution by providing an attenuator giving a loss to inter-symbol interference light and a means for overlapping inter-symbol interference light to which the prescribed loss is given with two-way main signal light. SOLUTION: At the time of conducting an outgoing signal test, for example, a transmitter 21-1 outputs an outgoing signal whose intensity is modulated by a signal given from a pulse pattern generator 15-1. The optical power of the outgoing signal is set by adjusting an attenuator 23-1. An attenuator 23-3 is adjusted and the optical power of inter-symbol interference light is changed. The inter-symbol interference light is overlapped with the outgoing signal through an optical switch 13-1 and a photocoupler 24-1, and inter-symbol interference quantity in a receiver 25-1 is set. An error rate measuring unit 16-1 connected to the receiver 25-1 detects a code error rate corresponding to inter- symbol interference quantity which is set by the attenuators 23-1 and 23-3 and measures the system margin in the outgoing direction.
