Title: Metallic coating composition
Inventor: HAMADA TAKAHIKO
IPC: C09D5/38
Filed: 1988-08-26
Abstract: PURPOSE:To obtain the title composition which scarcely undergoes seeding and thickening during its production and storage and has excellent color stability by using an aluminum powder subjected to chromate treatment. CONSTITUTION:This metallic coating composition is prepared from an aluminum powder subjected to chromate treatment. When an aluminum powder is subjected to chromate treatment, it is converted into a powder having a surface made sufficiently inert within a short time, hardly entering an undesirable reaction with a pigment, especially, an organic pigment an having excellent color stability. Since the treated powder has sometimes a colored surface, it can function as a pigment in a metallic coating composition, so that it is also possible to avoid the use of an expensive pigment or to decrease the number of kinds of pigments to be used.

Title: Discharge lamp lighting device
Inventor: MIKI NOBUKAZU
IPC: H05B41/24
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent the stress of a control power supply at the time of start and its reduction after lighting by obtaining the power supply of the separately excited control circuit of an inverter circuit converting the rectified filtered voltage into a high frequency and feeding it for a lamp load included in an LC resonance circuit from the voltage between both ends of a discharge lamp having the prescribed ratio or above between the rated voltage and starting voltage, and compensating the excessive feed at the time of start and deficiency at the time of lighting. SOLUTION: A filtered DC voltage is converted into a high-frequency voltage by switching elements S1, S2 driven by the signal from a control circuit IC1 and is fed to a discharge lamp LA via an isolation transformer T1. The impedance of an electric path for feeding the voltage of a control power feeder winding N3 to the control power voltage feeder capacitor C4 of the control circuit IC1 is changed by a parallel circuit of a resistor R3 and a switching element S3. When the ratio between the start voltage and rated voltage is five or above, the impedance of the electric path is made high at start and low at lighting to reduce stress, and the frequencies at start and lighting are set equal.

Title: Metal conductor for semiconductor device
Inventor: FUJII HIROYUKI
IPC: H01L23/495
Filed: 1981-12-25
Abstract: PURPOSE:To reduce faulty wire bonding and to produce lower-priced metal conductor by a method wherein a metal conductor wire bonding pad is selectively provided with a several mum-thick coating of Al, the metal composing the wire, by means of cladding, evaporation, or plating. CONSTITUTION:A Cu-made support 11 is integral with a lead-out tongue 12 provided with a 3mm.-wide wire bonding pad 13 plates with a 3mum-thick Al layer at its end. When a 200mum-diameter Al wire is bonded by means of ultrasonic fusion to said Al-plated pad 13, the rate of faulty wire bonding is not more than 0.05% of what is expected of the conventional Ni-plating or Ag-plating method. Further, plating overally the Cu-made support and lead-out piece with Ni prior to  Al application results in a roughly 20% rise in cost, which is only one third of  the cost a conventional Ag-plated support demands.

Title: Device for reinforcement of pixel addressing function in pulse width and position modulation system
Inventor: MAIKERU ESU CHIANCHIOSHI
IPC: G09G1/00
Filed: 1994-09-07
Abstract: PURPOSE: To reinforce the addressing function of a pixel without increasing the speed of hardware by selectively generating a multiple pulse in a preliminarily determined pixel clock cycle. CONSTITUTION: The synchronization of a video signal pulse generated from video data a raster output scanner and picture face is achieved by a system clock equivalent to a speed at which a pixel is exposed to the picture face. Therefore, it is necessary to increase frequencies for obtaining more satisfactory resolution by the faster clock. A video coupling logical block 149 allows a video signal from a video pulse logical block 131 to pass without changing it when a logic 0 is present in an inversion control line. When a logic 1 is generated in the inversion control line by a video pulse inversion control block 145, the video pulse signal from the block 131 is inverted, and a pair of video pulse are formed. Therefore, a reverse phase pulse is generated, and a multiple pulse is generated in a selected clock cycle.

Title: Crystal evaluating apparatus
Inventor: MITA AKIRA
IPC: G01N21/88
Filed: 1985-09-26
Abstract: PURPOSE:To measure and evaluate internal strain, dislocation net and the like in an epitaxial crystal layer in non-destructive way, by projecting probe light, which is polarized in one direction, on the epitaxial crystal layer, and detecting the light, which is outputted from the crystal layer and has the different polarization component. CONSTITUTION:Oscillated light from a laser 1 is introduced into a single mode fiber 3 through a SELFOC lens 2. The light is projected on an epitaxial crystal layer 7, which is grown on a substrate crystal 6 comprising a core layer 4 and a clad layer 5. Luminous flux 8 is outputted from the crystal layer 7. The polarization component, which is in the opposite direction to the incident light is made to pass an analyzer 9. The image of the light is formed on an infrared visicon 11 through the analyzer 9 and a lens system 10. When internal strain is yielded in the epitaxial crystal, the image of the transmitted light, which has approximately glass-state intensity distribution, is observed due to double refraction caused by the inner strain. When a dislocation net is present, partially bright parts 21 appear. When a moving mechanism is attached to the fiber 3 and the position of the incident light is moved, the bright parts are moved to parts 22. Based on the behavior of the movement, the position of the defect can be found.

The induced current 7, received at the steel tower 2, is fed to a filter in the transmitter/receiver 6 for the purpose of noise reduction. The filtered signal is amplified and transmitted through an output converting section to the transmission current transformer 5 thence to the receiving current transformer 4 on the next steel tower 2. When the operation is repeated sequentially, information can be transmitted to a remote central monitoring unit 8.
