Title: Reading method of electrostatic latent image
Inventor: KITAJIMA NOBUO
IPC: H04N1/29
Filed: 1982-02-15
Abstract: PURPOSE:To hold an electrostatic latent image for a long time after its formation and  to read out the image many times at optional times, by converting a dielectric comprising a photoelectric converting mechanism into a ferrodielectric substance that has spontaneous polarization in response to the electrostatic latent image. CONSTITUTION:A photoconductor 11 is coated on a transparent conductor 12, and a ferrodielectric substance 10 is put on the photoconductor 11, and an additional conductor 9 is coated on the substance 10. The voltage Vd1 is impressed between electrodes  9 and 12 by turning on a switch S2, and at the same time the image exposure light 21  is irradiated. In this case, the state of polarization has directivity in the state shown by  an arrow mark to form a polarization image corresponding to the original picture.  Then switches S2 and S1 are turned off and on respectively to expose the entire surface  of a photoelectric converting mechanism 13 to neutralize the conductor 11. In this case,  the state of polarization of the substance 10 is held in a state shown by an arrow  mark owing to the spontaneous polarization to form latent image. For the reading of  the latent image, the switches S1, S5 and S3 are turned off, on and off rspectively.  Then the beam radiated from a laser 18 scans the surface of the mechanism 13 via a scanner 17, and an electric signal is extracted along the latent image and through an amplifier 16.

Filed: 1993-02-10
Abstract: PURPOSE:To improve finished surface accuracy of welding tips by machining and shaping the tip surfaces of the welding tips by a cutting blade of the chip dresser so that these are formed into a conical shape.

Title: Production of differential thickness plated metal plate
Inventor: AZUMA TAKASHI
IPC: C25D5/16
Filed: 1979-02-28
Abstract: PURPOSE: To control the plate thickness of the metal plate to be plated respectively independeltly for the front and back and inexpensively produce the perfect differential thickness plated metal plate by closely contacting plastic non-metallic magnets at one or more places on the surface of the material to be plated under plating process.  
     CONSTITUTION: The metal plate to be plated 2 is contacted with a strip-from rubber magnet 1 in the guide roll 3a portion and while the contact state is being maintained, it is admitted into a plating cell 4. At the place of the guide roll 3c in the cell 4, the contact state is released; thereafter the metal plate 2 alone is delivered to outside the cell 4. In this case, the both are contacted closely by the strong attraction force acting between the metal plate 2 and magnet 1 so that the entry of the plating solution 6 into the contact portion 5 is prevented, and while it is passing the (a) and (b) portions, no plating is deposited on the fixing surface and only the other exposing surface is plated. As a result of this, the differences in the plating thickness proportional to the ratios between the effective lengths (a), (d) of the plating line and the lengths (a), (b) of the contacted materials are produced on the front and back of the metal plate 2, whereby the intended differential thickness plated material is obtained. Here, 7 in the figure denotes a drive roller and 8 an electrode for plating.

Abstract: PURPOSE:To improve the utilization efficiency of a radio wave by registering machine kind information of a mobile station in the subscriber table of a controller of an exchange. CONSTITUTION:When there comes a call from mobile stations 1-3, a base station 4 is subjected to trunk connection to an exchange 15 and a communication is executed, and when it is finished, a circuit is released. When a calling comes to the stations 1-3, the station 4 receives a call request signal from the station 15. From this signal, machine kind information of the stations 1-3 is extracted, a frequency band table 16 is collated, and a stand-by receiving frequency band is retrieved. In the case of calling to the station 1, a call is executed by an AMHz band, and in the case of calling to the station 3, it is executed by a BMHz band. In the case of calling to the station 2, the call is executed by the AMHz band. When there is an answer of the stations 1-3, the station 4 executes a trunk connection of the answer to the station 15, an exchange connection is executed and a communication is executed. Unless there is an answer of the stations 1-3 with respect to the call, the station 4 informs the station 15 about unconnectability. A controller 7 receives position registering information of the stations 1-3, registers it in a subscriber table 14 and prepares for generation of a communication request, and the utilization efficiency of a radio wave can be improved.

Abstract: PURPOSE:To eliminate an unnecessary light beam such as heat radiation light and external light, etc., from an optical fiber itself, and to emit only the heat radiation light from a minut cavity radiator, by providing an unnecessary wavelength compound eliminating means. CONSTITUTION:The heat radiation light from a minute cavity radiation 1 is transmitted in an optical fiber 2, and emitted from its light leading-out end 3. An emitted light 4 contains not only the heat radiation light from the minute cavity radiator 1 but also a wavelength component of a part of heat radiation light from the optical fiber 2 and external light 5.

It is allowed that the optical filter 6 does not receive a light beam which has been emitted from the light leading-out end 3 being the end part of the optical fiber 2, therefore, it is also allowed that the middle part of the optical fiber is cut and the optical filter 6 is inserted therein, and a light beam which is being transmitted is filtered.

Title: Apparatus and method for inspecting pattern
Inventor: KANAI TAKAO
IPC: G01N21/93
Filed: 1995-01-17
Abstract: PURPOSE: To detect a different part of two patterns without using a large-scale hardware and consuming a long time by vibrating-and-comparing patterns for every local area. CONSTITUTION: Binary image data of a pattern to be inspected are stored as an object data and a master data (S10, S12). Based on the data, a master pattern is first moved to a position where the master pattern nearly overlaps with the object pattern. The moving amount is stored as a master moving amount (S14). Then, data of each inspection block are sequentially extracted from the object data (S16). The master pattern is moved by the master moving amount for every extraction. The blocks are vibrated-and-compared in a predetermined range of the moved master pattern centering a position corresponding to the current inspection block (S18-S26). When the blocks are detected by the comparison to agree with each other, the master moving amount is updated based on an agreeing position (S30).  If the blocks are detected to be different, the vibration-and-comparison is carried out for the next inspection block without updating the master moving amount (S36, S16-S26).
