IPC: H05B3/20
Filed: 1988-02-01
Abstract: PURPOSE:To make it possible to form desirable irregularities in the surface of an insulation rubber sheet by heat pressing it through a fiber cloth applied on the surface of the insulation rubber sheet while heat pressing. CONSTITUTION:By heat pressing the surface of an insulation rubber sheet 2 through a fiber cloth 4, the insulation rubber sheet 2 fused by heat and the fiber cloth 4 penetrate each other tightly, and irregularities are formed in the surface of the insulation rubber sheet 2 corresponding to the irregularities, that is, texture for woven fabric, in the surface of the fiber cloth 4. The surface of a die 3 where it contacts the insulation rubber sheet 2 may be flat, therefore, and need of using one having irregularities formed in it, like conventional ones, is eliminated. In addition, because the fiber cloth 4 has air permeability almost uniformly, and air escapes out through gaps between fibers, so occurrence of air stay at particular positions at the time of heat pressing is eliminated. Irregularities can thus be formed desirably in the surface of the insulation rubber sheet.

Title: Ultrasonic flaw inspection device
Inventor: KATAMINE AKIHIKO
IPC: G01N29/30
Filed: 1987-02-02
Abstract: PURPOSE:To perform a self-judgement of whether or not the contacting state of a device itself, and the device and a body to be measured by providing a multi-probe, a pulse generating circuit, a gate circuit, a signal judgement processing circuit, etc. CONSTITUTION:When the pulse generating circuit 2 outputs a synchronizing signal at a prescribed period while the multi-probe 1 is arranged on the surface of the body to be measured, a transmission part 3 is triggered with this signal. Consequently, vibrators 1a and 1b for transmission send out ultrasonic waves of prescribed frequency at the same time in synchronism with the synchronizing signal, so that they are propagated in the body to be measured. Then an echo from the body to be measured is extracted through a vibrator 1c for reception, amplified by a reception part 4, and inputted to a gate circuit 5. This circuit 5 is triggered with the synchronizing signal from the circuit 2 to generate a gate signal and the output of a reception part 4 is passed only in the generation period of the gate signal and inputted to the signal judgement processing circuit 6. At this time, when the contact state between the body to be measured and probe 1 is defective, a warning is outputted to a display part 7. Thus, a self- judgement of whether or not the contact state is normal is performed.

Filed: 1995-01-17
Abstract: PURPOSE: To obtain an inspection equipment for making a decision of pass/fail by automatically detecting an unsealed part of a sheet in a package, e.g. a PTP package. CONSTITUTION: A CCD camera 10 picks up the surface image of a package and delivers a gray level image data to an edge extracting section 16 where the edge is extracted. Consequently, a grid-like pattern present at a sealed part of the package is embossed. The image is sent out to a line width enlarging section 18 where the line width is widened by substituting for the minimum gray level among eight nearby pixels using a minimum value filter thus compacting the grid-like mesh. When the image is binarized at a binarization section 19, the pocket part, the grid-like mesh, and the unsealed part are represented by white pixels.  The pocket part and the grid-like mesh are substituted, respective at a masking section 20 and a noise removing section 21, by black pixels and a decision section 22 makes a decision that an unsealed part is present when more than predetermined number of white pixels are present.

Title: Cut change detector for moving picture
Inventor: AKAHORI HIROSHI
IPC: H04N5/262
Filed: 1993-02-10
Abstract: PURPOSE:To improve the detection performance by detecting an edge in the unit of frames, obtaining a difference of an edge histogram of timewisely different frames and comparing the result with a prescribed threshold value so as to detect a cut change. CONSTITUTION:A moving picture signal comprising R, G, B signals of a picture signal input section 1 is converted into a luminance signal by a picture signal conversion section 2. An edge detection section 3 applies filtering processing to the luminance signal to obtain the intensity of the edge. An edge histogram generating section 4 divides the intensity of edge into 16 divisions to obtain a histogram of the moving picture signal by one frame and inputs the result to a histogram storage section 5 to delay the histogram. A histogram difference detection section 6 obtains the difference between the histogram delayed in one preceding frame by the storage section 5 and a current histogram. Then a threshold value processing section 7 compares a value obtained by the detection section 6 with a prescribed threshold value and detects it as a cut change when the value is larger than the threshold value. Thus, the detector immune to a color change and a luminance change is obtained.

Title: Semiconductor device
Inventor: NAKAMURA KUNIHIRO
IPC: H01L21/761
Filed: 1980-02-25
Abstract: PURPOSE:To raise surge voltage resistance in the reverse direction by a method wherein on the surface of an n<-> epitaxial layer held between an n<+> cathode layer  and a p<+> separating layer is provided an n<+> layer in specified width which is separated at distances x2 and x1 from both cathode and separating layers respectively  and surrounds the cathode layer and the distance x1 is made smaller than the thickness of the epitaxial layer directly under the cathode layer. CONSTITUTION:When the surge voltage in the reverse direction is applied to the anode 6 (p<+> separating layer 4) and the cathode (N<+> layer 3), it makes punch- through between the layers 8 and 4, a current flowing along the surface of the epitaxial layer 2 flows inside of the epitaxial layer 2 between the layers 8 and 3, and the resistance thereof restricts the punch-through current and increase voltage breaking strength. The dimension x2 is made large, (w) is made small and the resistance of the n<+> layer 8 along the direction (y) is made large, thereby the expansion of the punch-through current in the direction (y) being prevented and current restricting resistance being increased. In the case when forward voltage is applied between the electrodes 6 and 7, the surface resistance of the epitaxial layer 2 is increased due to the restricting resistance, but the drop of voltage is not increased since the current flows mainly from the n<+> layer 3 to a p type substrate 1 just under the layer 3.
