Title: Device and method for inspecting pattern of printed circuit board
Inventor: TOKUTAKE SHIGERU
IPC: G01N21/956
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To surely detect a pattern with a relatively simple configuration. SOLUTION: When a piezoelectric film 3 consisting of a piezoelectric material with a conductive film 4 on one surface is provided, the piezoelectric film 3 is adhered onto a printed circuit board 1 and a high-frequency signal is given between the conductive film 4 and a wire pattern 2 to be inspected. The region of the piezoelectric film 3 located between the conductive film 4 and a wire pattern where a high-frequency signal is given vibrates due to piezoelectric phenomenon. Laser beams from a laser light source 7 and laser beams reflected from the piezoelectric film 3 are applied to a light reception element 8. The optical path length of laser beams reflected from the pattern of the wire pattern being inspected slightly changes due to the vibration of the piezoelectric film 3 above.  As a result, the amplitude of light obtained by the interference with the laser beams directly applied to the light reception element 8 changes with a slight time interval, thus confirming the arrangement of the wire pattern to be inspected.

Abstract: PURPOSE:To control temperature rise in a device and overall power consumption as far as possible and make the device compact by heating only a section in which a latent image erasing means corresponds to a latent image formed previously under the non-presence of a contact material. CONSTITUTION:In the case an image is removed, consideration should be paid to the heating of a thermal head 22 at the time of forming a latent image to be synchronized with the heating for removing the image. The latent image is formed on a recording body belt 1 heated in liquid by the thermal head 22, and the recording body belt 1 is carried by a driving roller 71, developed, transferred and cleaned, and simultaneously the belt reaches an image removing means (ceramic heater 6). The heat-on time of the ceramic heater 6 is set in consideration of the relation between the distance from a latent image forming section and the feeding speed of the recording body belt so that sufficiently high temperature is developed when the latent image forming section reaches the position of the heater. It is preferable that the overall surface of a recording body is heated prior to the formation of latent image under the non-presence of a contact material and the image is removed.

Abstract: PURPOSE:To make it possible to produce an anode oxide with different thickness for each wiring, by applying a voltage to at least one wiring line for a different application time out of wiring lines put in contact with the anode. CONSTITUTION:A first pair of electrodes made up of a first wiring 3, a second wiring 4, each as an anode, and a cathode 2 formed on an insulating substrate 1 is put in a chemical solution. At the same time, a second pair of electrodes 8 is provided for collecting an impurity in the chemical solution. When the impurity is deposited and the isolated state is lowered between the electrodes for the anode oxidation, an applied voltage is reduced to zero or the anode is subjected to a negative voltage transiently, and after that the applied voltage is returned to the same voltage as before. In these steps, the isolated state between the first wiring 3 and the second wiring 4 is improved. As a result, the anode oxidation step can be carried out in a good isolated state by reducing now and then the voltage to zero or applying the negative voltage intermittently to the anode in a normal anode oxidation step.

Abstract: PURPOSE: To speedily, exactly and automatically measure the threedimensional position and attitude of a car body by finding the distance by measuring the time of reflected and returned sound waves or laser beams from the surface of an object. CONSTITUTION: A car body 16 is provided with three gauge holes 24 for watching respective gauge marks only with one of cameras 26.

When the car body 16 exists at that zero deviation position, a body coordinate system(BCS) is coincident with the VCS. When moving the car body 16 from the zero deviation position, the movement of rigid body received on the car body is completely determined by transformation for relating the VCS with the BCS.  This transformation is defined concerning the VCS and the position and azimuth of the BCS, namely, the position of the car body 16 can be determined.

Title: Reflecting mirror for road, provided with defrosting means
Inventor: IIJIMA SHUICHI
IPC: E01F9/00
Filed: 1993-12-25
Abstract: PURPOSE:To defrost a reflecting mirror, by providing a heatintroduction means of natural convection or the like at the rear face of the mirror body and rapidly taking the heat of the air at the rear face of the mirror and preventing the mirror face from being cooled by radiation cooling. CONSTITUTION:A clearance is provided between a mirror face 1 and the rear plate 4 and the mirror face 1 and the rear plate 4 are connected to each other with a connecting tool 11 to make a unit body and the clearance formed between them is used for the introduction part 3 of the air. The inside space where natural convention is brought through the introduction part 3 is used as a heat-introduction means 2. Since the natural convection is performed through the introduction part 3, the mirror face 1 can be prevented from being cooled by radiation cooling and since the mirror face 1 absorbs rapidly the heat from the air, the temp. of the mirror face is gradually lowered. The difference of temp. between the mirror face and the outside air is extremely small and hence, dewing on the mirror face is completely prevented. When the atmospheric temp. abruptly rises the mirror face follows the air temp. by the means 2 and gets warm to prevent frosting of the face. In this way, frosting can be securely prevented.
