Title: Bonding tool and bonding method for semiconductor chip using the same
Inventor: OKURA HIDEAKI
IPC: H01L21/60
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To secure parallelism between the face of a semiconductor chip and the surface of a mounting substrate, even if deformations such as warpage due to heat occurs on the mounting substrate. SOLUTION: Since the surface of a mounting substrate 28 having a warpage is not parallel to the face of a semiconductor chip 26, for example, a bump on the face of the semiconductor chip 26 is brought into contact nonuniformly with a wiring pattern on the surface of the mounting substrate 28. The dispersion of a pressure value at that time can be detected by a plurality of pressure sensors 20 installed in a bonding tool 10, the inclination of the head face of an adsorption head part is adjusted so that the dispersion of the pressure value is corrected, and the pressure value is uniform by the use of head face adjusting part 18, and the face of the semiconductor chip 26 becomes parallel to the surface of the mounting substrate 28. Then, the bump of the semiconductor chip 26 and the wiring pattern on the surface of the mounting substrate are flip-chip connected through heating and pressurization.

Title: Magnetostatic wave device
Inventor: OKADA TAKEKAZU
IPC: H01P7/00
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a magnetostatic wave device with which impedance matching is facilitated even when a magnetostatic wave filter in small size is used, and it is not necessary to use the amplifier of high output power. SOLUTION: A signal is inputted to an input terminal 30, and high-level and low-level signals provided by a first directional coupler 28 are inputted to two magnetostatic wave filters 12 and 14. At the first magnetostatic wave filter 12, the amplitude of a main signal is limited and a noise is outputted without limiting its amplitude. At the second magnetostatic wave filter 14, all the signals are outputted without limiting their amplitudes. The phase of an output signal from the second magnetostatic wave filter 14 is inverted by a 180 deg. phase shifter 34 and this signal is synthesized with the output signal of the first magnetostatic wave filter 12 by a second directional coupler 32. As circuits for impedance matching, capacitors 38 and 40 are connected on the input side of the first magnetostatic wave filter 12 and the output side of the second magnetostatic wave filter 14.

Title: Latch circuit
Inventor: JIERARUDO ADORIAN MAREI
IPC: H03K5/135
Filed: 1984-06-15
Abstract: An edge triggered polarity hold, clocked latch circuit is disclosed which requires the use of only a single clock line for operation. The latch circuit comprises three set-reset type latches (1, 2, 3). Each of two latches (1, 2) receives one set and one reset signal. The third latch (3) receives two reset signals and one set signal. A single clock signal is applied jointly to a reset terminal of the third latch (3) and of one of the first two latches (1, 2). A data signal is applied to the set terminal of the third latch (3). The other of the first two latches (1,2) constitutes the output latch (2) and is connected to receive the outputs of the remaining latches. The output latch (2) produces an output equal to an input data signal upon each occurrence of the leading edge of an input clock signal. The output is held (latched) until the occurrence of the next clock signal when the output becomes equal to the then existing input data signal.

Title: Choke coil for suppressing harmonic current
Inventor: KAMOI KENJI
IPC: H01F17/04
Filed: 1995-05-22
Abstract: PURPOSE: To miniaturize a component while satisfying the standards regarding a high-frequency current. CONSTITUTION: A choke coil 5 for suppressing a harmonic wave comprises stepped parts 19 having different heights at the end faces as seen from the side formed at the upper ends of a main leg and a side leg 18. Gaps 21 having different space widths are provided between the parts 19 and the lower end 30 of the upper magnetic member 13. The narrower the space widths of the gaps 21 are, the less the input current of the region is preferentially saturated. Accordingly, the inductance is changed largely with a light load, the inductance is changed small with a heavy load, and hence the inductance characteristics conforming to the standards is obtained. Since the core is saturated partly from the region with smaller input current, the entire shape can be reduced.

Title: Treatment of iron-containing dust obtained upon manufacturing iron or steel
Inventor: KARERU UIREMU JIYAN HOOIKAASU
IPC: C21B15/00
Filed: 1985-06-05
Abstract: Iron is recovered from an iron containing dust obtained in processing iron or steel by dissolving iron and bivalent metals being present in said dust in an acid. Subsequently the iron is precipitated by adding an alkaline substance or ammonia to adjust the pH to 5 to 8. Before or during precipitating the iron the bivalent ions as present such as zinc, cadmium and lead are converted into a soluble complex by means of a complexing agent. Preferred complexing agents are polyamines, particularly triethylene tetramine being an excellent complexing agent for zinc. The precipitated iron hydroxide is recovered and may be reused. The process may be separated more than once in the same solution, thereby providing a final solution containing considerable amounts of zinc, cadmium, or other bivalent metals which may be separated by boiling or precipitation. The complexing agent may be recovered by destillation after having made the complexes strongly alkaline or by precipitation by adjusting the pH to 1 and recovering the salt of the complexing agent such as a hydrochloric acid salt of the complexing agent.

Abstract: PURPOSE: To detect automatically the best value of a recording level by increasing or decreasing the recording level so that the number of times when a reproduced signal level exceeds a standard value will between its least bound and greatest lower bound.  
     CONSTITUTION: A signal recorded on tape 7 is reproduced by reproducing head 10 in an electric signal, which is amplified and then converted into a direct-current level by detection circuit 15 before being inputted to comparator 16. As the reference signal of comparator 16, the output of D/A converter 17 is used and the output of comparator 16 is inputted to PIA18. Here, a comparison output from comparator 16 is sampled N times at fixed intervals of time to count the number of times (n) when the output is higher in level than the reference signal. The recording level when the number of times (n) is between N 1  and N 2  (N 1 >N 2 ) is regarded as the best recording level. If (n) is less than N 2  or greater than N 1 , the recording level of recording level setter circuit 4 is increased or decreased by one step by control signal 101 and comparison and counting are repeated. Those operations are repeatedly performed until (n) is between N 1  and N 2  for fine adjustments.
