Title: Au alloy brazing material for assembling semiconductor device
Inventor: UCHIYAMA NAOKI
IPC: C22C5/02
Filed: 1987-01-20
Abstract: PURPOSE:To obtain an Au alloy brazing material having excellent oxidation resistance by using a material in which one kind of Sn, Ge and Si in fixed wt.% and one kind or two kinds of a rare earth element, B and Al in the quantity of predetermined ppm are contained and the remainder consists of Au and an unavoidable impurity. CONSTITUTION:When one kind or two kinds or more of a rare earth element, B and Al in 10-1500ppm are contained into an Au alloy brazing material having a composition in which one kind of Sn:14.5-90.5%, Ge:5.5-50.5% and Si:0.5-6.5% in wt.% is contained and the remainder is composed of Au and an unavoidable impurity, Sn, Ge and Si as alloy contents at the time of brazing when semiconductors are combined form oxides and the alloy contents do not exist as a nonmetallic inclusion on the interface of brazing, thus preventing the lowering of wettability and bonding strength and the deterioration of the thermal and electric conductivity of a brazing section. The alloy solder material is acquired in such a manner that an ingot is manufactured under normal conditions from an alloy molten metal having a prescribed component, hot and cold rolled, and changed into a chip as a ribbon material.

IPC: B60Q1/04
Filed: 1991-01-31
Abstract: PURPOSE:To provide a lighting device for discharge lamp such as metal halide lamp so as to put out the light for short time without hindrance. CONSTITUTION:When a lamp switch is turned ON at a time t1, a head lamp (discharge lamp) is lighted and is in a luminous flux phi1 of constant state, and when the lamp siwtch is turned OFF at a time t2, the luminous flux of the head lamp is reduced to phi2, of extinction mode. When the lamp siwtch is turned ON again at a time t3 before a timer T is counted out, the head lamp is not re-started but returned to the luminous flux phi1 of constant state. When the lamp switch is turned OFF at a time t4, the lamp is extribuished since it is in the extriction mode, when the timer T is counted out at a time t5. The head lamp is flashed in a pseudo-mode accordance to the turning ON/OFF of the lamp switch, and the turning out of the light for a short period of time can thus be carried out smoothly.

Title: Filter processing method for image signal
Inventor: IKUTA KUNIO
IPC: G06T5/20
Filed: 1989-01-19
Abstract: PURPOSE:To remove noise and to clearly store an edge by setting up the 1st and 2nd thresholds set up in accordance with the image signal level of a target picture element as upper and lower limit values and averaging a corrected image signal obtained by restricting the level of the image signal as a filter- processed image signal.

Since noise in the section determined by the 1st and 2nd thresholds THH, THL is averaged and the level of the image signal PS on the outside of the range is corrected by the 1st or 2nd threshold THH or THL, a difference between the level of the processed image signal NS of the target picture element obtained by averaging the signals and the level of the unprocessed image signal PS is reduced. Thus, the noise can be sufficiently removed and the edge can be clearly stored.

IPC: B21D24/02
Filed: 1980-02-02
Abstract: PURPOSE: To reduce the time for a preparatory plan and prevent impact during ascending of a pad by providing two systems combining an air circuit of a large diameter and an air circuit of a small diameter to an air die cushion.  
     CONSTITUTION: In the case of using an air tank 2, a solenoid valve 5 is changed over to communicate the pilot air of the port P to the port B and a shuttle valve 12 is operated to close the port P 1  and open the port P 2 , thence a valve 11 is closed. In synchronization with this, the air from the port B of the solenoid valve 5 operates a master valve 7 to communicate the ports P 1  and A, so that the air in the tank 2 is supplied through a valve 7 to the air die cushion 1. Since the circuit of the valve 7 is of a small diameter, the pad of the die cushion 1 ascends slowly. A cam 13 operates a valve 4 near the upper limit of the pad and the air of the port B of the solenoid valve 5 enters the port P 3  of a piston valve 3; at the same time, it enters the port P 2  of a master valve 6, thereby changing over the valve 6. This communicates the ports P 1  and A of the valve 3, so that the air of the tank 2 is supplied to the die cushion 1.

Title: Optimum control system for stepping motor
Inventor: FUJIOKA ICHIRO
IPC: B41J19/30
Filed: 1989-01-20
Abstract: PURPOSE:To easily and efficiently obtain optimum slewing characteristic without mechanically regulating by selecting slewing pattern data for performing optimum slewing characteristic which can abruptly rise with small vibration for each printer at the time of regulation. CONSTITUTION:The magnitude of a vibration generated at a rising part depends upon slewing pattern data used for execution, and its state is exhibited in a reading pulse train of a longitudinal bar by a mark sensor 12. A slewing regulation program 19a analyzes variations in a pulse interval, measures the magnitude of the vibration (Vmax-Vtyp), (Vtyp-Vmin) in the vicinity (d+ or -DELTAd) after a predetermined distance (d) is moved after the slewing is started, determines whether the value falls within the allowable errors t1, t2 of a motor speed or not, and determines to employ present slewing pattern data or to select other slowing pattern data to again execute. For example, characteristic III falls within the allowable error over the allowable errors I, II. Thus, the characteristic III is selected as optimum.

Abstract: PURPOSE:To reduce the unnaturalness generated in an interpolation image at the time of generating the interpolation image to be positioned spatially or hourly between original images from two pieces of original images. CONSTITUTION:On an original image (22), a partial area (5) corresponding to a targeted small area (4) is set. Subsequently, a small part (6nn) on an original image (32) opposed to a small part (511) in the partial area 5 by holding the notice small area (4) therebetween is determined, and with regard to images of those small parts (511), (6nn), a distance d11 is calculated. With regard to all the small parts (511)-(5nn) in the partial area (5), distance d11-dnn are calculated in the same way as the calculating method, and the shortest one of those distances d11-dnn is selected. Next, by an interpolating operation using the small part image which becomes the root of the shortest distance, the image of the targeted area (4) is derived. By setting the targeted small area (4) extending over the whole frame (12), and applying the interpolating method to each of them, an interpolation image N is derived.

Title: Liquid crystal device and method and device for addressing liquid crystal device
Inventor: BONNETT PAUL
IPC: G09G3/20
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To reduce the heating of a liquid crystal device and a decrease in display contrast. SOLUTION: A liquid crystal devices is multiplex driven by scanning signals which are imparted sequentially to electrodes 14a..., together with data signals imparted to electrodes 16a.... The first and second sets of electrodes specify a plurality of picture elements. A pattern to be shown the device determines a waveform imparted to the electrode 16a..., the waveform being variable between both of extreme frequencies, i.e., a high frequency matching the same condition of the picture elements and a low frequency matching the conditions of the picture elements which vary alternately between adjacent lines. This adversely affects the performance of the device, particularly in terms of contrast. To solve and improve such a problem, a line driver 18 outputs a scan signal obtained by adding a low frequency signal to a scan signal including known strobe pulses. The low frequency signal reduces the effect of each extreme data signal frequency on the picture elements.
