Title: Grid-controlled gas discharge lamp
Inventor: KURASU BUEGUTAA
IPC: H01J61/10
Filed: 1991-12-24
Abstract: PURPOSE: To provide a grid control gas discharge lamp in which a lamp itself functions as a part of an actuating circuit. CONSTITUTION: A low pressure discharge lamp (like a fluorescent lamp) has a wire net grid 32 placed in a lamp container 10 so that electrons passing between electrodes are interrupted. From this grid 32 a lead wire 38 is extended to outside of the container 10, and when negative voltage to surrounding plasma is applied to this grid, the lamp is switched off. In this grid control gas discharge lamp, a solid power switch is not required. Lamp current itself passes through the lamp and does not go through an electron stabilizer/lamp actuating circuit. Since the lamp current does not go through the actuating circuit, heat radiation is no more a problem. This grid control discharge lamp makes it easy to design circuits.

Title: Apparatus and method for inspecting bonding wire
Inventor: SUGAWARA KENJI
IPC: G01R31/28
Filed: 1991-12-02
Abstract: PURPOSE:To take in an image without impairing a ball shape even if a foreign matter exists between a ball and image taking optical means and to inspect the ball shape by inspecting the ball by applying a dark field illumination to the ball to be inspected to brightly illuminate the ball. CONSTITUTION:A ball 5a is illuminated at a low angle by a low illumination angle ringlike illuminator. Then, a reflected light on a mirror-surface of a semiconductor chip 1 is not incident to an objective lens 24 but dark-illuminated. However, the reflected light direction on the part of the ball 5a is mostly incident to the lens 24 to brightly illuminate the ball 5a. An aperture diameter of a motor-driven diaphragm 51 is increased to set a shallow focal depth, and a focal distance is set to a surface of the chip 1. Then, since a reflected light from a wire 5 is less, only the ball 5a is brightly illuminated. Accordingly, even if a foreign matter exists between the ball and picture taking optical means, the shape of the ball 5a can be inspected irrespective of the pattern shape, brightness of the surface of the semiconductor.

Title: Detecting method for change state of substrate
Inventor: INOUE KIYOSHI
IPC: G01L1/12
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To establish a detecting method for the change, the stress, the strain, the fatigue or the like of a substrate by a method wherein a fatigue degree based on an instantaneous stress value and a long-term stress value which are detected by a change in the electric resistance value of a magnetic-substance detecting piece is detected on the basis of a change in a magnetic characteristic. SOLUTION: A magnetic substance has a property that it is highly hard, that it is fragile, that it is highly corrosive and that it is broken down easily by a repetitive stress. A detecting piece detects the pressurization force, the fatigue or the like of a substrate on the basis of the coercive force, the magnetic flux density, the magnetoresistance or the like of a magnetic-characteristic detection value. The detecting piece is arranged directly with reference to a stress generating body, a position which generates the fatigue is grasped, or a change in a magnetization interval is measured, and the generation of the fatigue is estimated.  For example, in a magnetism detecting structure by a detecting piece, a magnetic-flux detecting element 3 is bonded and fixed to an element-material central high-strain receiving part 2 which detects fatigue magnetically, and strain application grip parts 5, 6 are formed of a corrosion-resistant material. Members which receive a strain are coupled to external bonded parts 9, 9', and a connection part 8 is screwed and then brazed. Thereby, the fatigue can be estimated in a wide range.

Title: Filter and decoder using it
Inventor: ONISHI SHINJI
IPC: H04N19/136
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To reduce mosquito noise of block-processed image data without increasing the circuit scale. SOLUTION: Input image data are fed sequentially to delay elements DL302-305 and a noted picture element is given to the DL 303. Difference absolute value calculation circuits 306-309 calculate absolute values of difference between the noted picture element value and a left adjacent picture element value and between the noted picture element value and a right adjacent picture element value. Comparator circuits 311-314 allow switches 316-319 to select a corresponding picture element in the case of each difference value < threshold level, and to select null in other cases. A switch 101 selects the noted picture element or null depending on number of selected and corresponding picture elements. An adder 102 adds values selected by the switches 101, 316-319 and the added output is averaged by shifting bits of the output at a shift register 103 depending on the count of the counter 315.

Title: Manufacture of gallium nitride compound semiconductor light-emitting element
Inventor: SONOBE MASAYUKI
IPC: H01L33/32
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a crystal of high performance by suppressing warpages occurring in a wafer (including a crystal layer grown with sapphire substrate) which prevents proper crystal growth, when a heterojunction layer comprising a GaN compound semiconductor layer is crystal grown on a sapphire substrate. SOLUTION: An active layer 3 of InGaN, while being sandwiched between an n-GaN clad layer 2 and a p-AlGaN clad layer 4 is grown to form a hetero structure. Here, large change in growth temperature required for it results in difference in thermal expansions between a sapphire substrate 1 and a clad layer 2 for causing warp of a wafer. In order to relax warping, a groove 1g is formed on a sapphire substrate surface, where a semiconductor crystal laminated before crystal growth. The groove 1g absorbs expansion/shrinkage caused by thermal expansion, for relaxing warping. The groove may be used in common with that used for dicing.

SOLUTION: The main body part 11 is provided with the substrate 13 of a rectangular parallelepiped, whose dielectric constant is about 6.0 and which is mainly composed of barium oxide, aluminum oxide and silica, a conductor 14 which is spirally wound in the longitudinal direction of the substrate 13, a feeding terminal 15 and a free terminal 16. The pedestal part 12 is provided with a substrate 17 whose dielectric constant is about 4.8 and which is composed of glass epoxy resin and outer electrodes 18 and 19. The feeding terminal 15 and free terminal 16 in the main body part 11 are electrically and mechanically connected to the outer electrodes 18 and 19 of the pedestal part 12 by solder and the like.  Since capacity generated between the conductor 14 of the main body part 11 and the ground electrode at the back of a circuit substrate can be reduced, the deterioration in the gain of the chip antenna 10 and the shift of the center frequency can be suppressed.
