Title: Probe card and semiconductor device
Inventor: MORI SHIGERU
IPC: H01L21/66
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To prevent the contact failure with an electrode and the deformation of an electrode surface by burying a wiring tip part into a plastic or elastic anisotropic conductive film. SOLUTION: A probe card is provided at the upper part of a semiconductor device 4 to be measured. A group of wires 21 are positioned so that they oppose a group of bump electrodes 5 of the semiconductor device 4. The probe card is lowered and the semiconductor device 4 is pressed with a proper pressure. In this case, a part between a tip part 21a of the wires 21 and a bump electrode 5 out of the anisotropic conductive film 23 is compressed, the density of a conductive material 26 at the compressed part increases, and a conductivity in a compression direction increases. Therefore, an electrical contact can be obtained, thus measuring electrical characteristics.  Even if the tip part 21a deviates from the bump electrode 5, a region where the tip part 21a and the bump electrode 5 are close each other is compressed, the density of the conductive material 26 increases, and a conductivity increases, thus obtaining an electrical contact and measuring electrical characteristics.

Title: Rack and its manufacturing method
Inventor: YABE CHIAKI
IPC: B21K1/76
Filed: 1981-06-09
Abstract: PURPOSE:To improve working accuracy of the effective engaging portion of a rack with a pinion by disposing a relief groove for a finish machining tool along the root of the rack. CONSTITUTION:A rack material is molded to form a substantially V-shaped primary tooth surface 8 indicated by an imaginary line. The depth of the primary tooth surface 8 is larger than the grain depth of cut worked in a conventional way. Subsequently, a secondary tooth surface 9 is molded. The secondary tooth surface 9 presents a final tooth form and has an easier grade than the primary tooth surface 8, the grain depth of cut thereof being smaller than that of the primary tooth surface 8. Therefore, in the vicinity of the root, a square portion 10 is formed between the primary and secondary tooth surfaces 8, 9, and the bottom of the primary tooth surface 8 is a relief groove 11. In case of working near the bottom of the secondary tooth surface 9, the relief groove 11 keeps a cutting tool from contacting the primary tooth surface 8, which can reduce cutting resistance and improve working accuracy.

Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To make a connection number non-disclosed when the connection number is transmitted by being added to a telephone number of a called party with respect to a communication equipment. SOLUTION: When the called party is called via a telephone line, the connection number is determined as to whether it is included in a transmission code or not by a CPU (S4). When the connection number is included in the transmission code (S4: YES), the transmission code is transmitted without displaying the transmission code on a display by the CPU (S5). After that, the temporarily stored transmission code is erased from a redial buffer area (S8) and retransmission of the transmission code including the connection number is disabled by the CPU.

Filed: 1991-04-19
Abstract: PURPOSE:To provide the auto iris device which automatically perform exposure control over image pickup operation under either of rear light and excessive follow light conditions. CONSTITUTION:An image pickup signal from an image pickup device 11 is converted by an A/D converter 18 and a light measuring circuit 12 calculates the load mean value of a brightness signal included in the digitized image pickup signal. A brightness histogram calculating circuit 15 calculates a brightness histogram according to the brightness signal and an arithmetic circuit 16 judges whether or not exposure, i.e., reference brightness needs to be corrected according to the calculated brightness histogram and outputs a correction value for the reference brightness according to the brightness pattern of an image to a reference brightness setting circuit 14 when the correction is necessary. The reference brightness setting circuit 14 sets the reference brightness according to the correction value and a comparison control circuit 13 controls the aperture for exposure according to the deviation between the calculated load mean value and the reference brightness from the reference density setting circuit 14. Consequently, feedback control over the exposure aperture is performed.

Title: Scribed steel plate
Inventor: HAYASHI YUTAKA
IPC: G01B11/16
Filed: 1978-07-20
Abstract: PURPOSE: To obtain scribed steel plate suitable for measuring deformation caused by pressing by making the thinkness of pattern 2 to 7μ, thickness of pattern curve 0.15 to 0.25 mm and area rate of pattern curve 30% or less.  
     CONSTITUTION: A specified pattern is printed on the scribed steel plate by the use of film. When the pattern is overthick, it is removed by rubbing with tools, when it is overthin, no pattern is made clear in processing the plate. Thus the thicknes of pattern is selected in the range from 2 to 7μ, preferably 3 to 5μ. For the thickness of pattern curve, it is necessary to previously give the thickness which can be measured by the naked eye even if the curve is thined by pressing, the curve thickness is selected in the range from 0.15 to 0.25 mm. The area rate of pattern curve is made 30% or less in order to suppress the frictional resistance between the pattern and the surface of press mold. In this way, scrived steel plate suitable for measuring the deformation caused by pressing can be obtained.

Abstract: PURPOSE:To effectively utilize a memory cycle without disturbing normal operations, by executing refreshing operations in a cycle which requires a long time. CONSTITUTION:In parallel with the input of line addresses for outside of 10 bits from the 4th bit to the 13th bit, refreshing address setting signals 22 rise by the operation of a control signal generating circuit 11 and a refreshing line address is transmitted to a line decoder 6 from a refreshing address counter 21.

This background refreshing cycle is completed when loading of the line addresses for outside is terminated and resetting is completed. At the same time, the refreshing address counter 21 is subjected to increment to provide for the next refreshing cycle. Similar background refreshment can be caused to be executed even in a long instruction cycle, such as data input/data output, etc., which requires a long time.

IPC: H04N5/18
Filed: 1983-05-20
Abstract: PURPOSE:To realize a stable clamp circuit without being subject to the effect of variation in a circuit element by opening a variable voltage source at a video period so as to set a discharge time constant higher than a charging time constant. CONSTITUTION:An electric charge is applied to a capacitor 2 via a resistor 11 from an emitter of a transistor (TR) 42 at charging. In taking a value of a resistor 11 sufficiently larger than a video signal source impedance 50 in this case, the operating waveform distortion of the clamp circuit is neglected. A current source 53 is cut off at discharge, then the TR42 is also cut off, and the electric charge in the capacitor 2 is discharged by a current flowing to resistors 11, 12 and a base current of a TR16 in this case. The base current of the TR16 is neglected by taking a value of a resistor 27 sufficiently larger. Then, the ratio of the charging/discharging electric charge is expressed as AX(R11+R12)/R11, in which a term giving an effect of variation is not included, thereby stabilizing the clamp circuit, where A is a constant, and R11, R12 are resistance values of the resistors 11, 12 respectively.

Abstract: PURPOSE:To constitute a carriage and a magnetic head at the height of low precision by allowing the guide shaft of the carriage, on which the magnetic head is mounted, to rise and fall and adjusting the height of the guide shaft to allow the height of the magnetic head to coincide with that of a flexible disk.
