Patent JP-H0637443-A (JP)
Title: Method of soldering
Inventor: TASHIRO JUNICHI
IPC: H05K3/34
Filed: 1992-07-20
Abstract: PURPOSE:To solder a flat lead to a flat pattern precisely by using a suction head that moves to correct the deformation of the lead. CONSTITUTION:When a bonding tool 6 descends to bring the end 5A of a flat lead 5 down into contact with a solder bump 3 on a foot pattern 2, the bonding tool is stopped and the solder bump is melted by a heating chip 9. Then, the bonding tool is slightly depressed so that the lead end 5A may come into close contact with the molted solder. After a predetermined period of time, the bonding tool is further depressed to force the lead end 5A against the foot pattern. According to this method, the lead end is prevented from bending, and further it is soldered to the center of the foot pattern since it is kept in contact with molten solder for a predetermined time.

Abstract: PURPOSE:To enable the mass production of various-shaped burning jigs with high strength at a low cost by forming weight composition comprising heat- resistant inorganic fiber, alumina, kaolin and silica sol each comprising of composition by weight of specific range respectively, and making the total content of iron oxide and titanium oxide to be 0.4% or less. CONSTITUTION:The composition by weight of a heat-resistant inorganic fibrous ceramic burning jig comprises 10 to 40 of heat-resistant inorganic fiber, 20 to 60 of alumina, 5 to 30 of kaolin, 0.3 to 4 of silica sol in its solid content, and 0.15 to 6.5 of water-soluble rubber in terms of solid content. In the case where the total content of iron oxide and titanium oxide is 0.4% or less, a chemically strong substance that does not react with electronic parts being the products to be burned is obtained during burning. Heat-resistant inorganic fiber enables the weight of a molded product to be reduced and enhances it heat impact resistance, alumina powder enhances its heat resistance and mechanical strength, and kaolin and silica sol harden a molded product. Thus, ceramic burning jigs with high strength and having various shapes can be produced in large quantities at a low cost.

Title: Vibration meter with built-in detector and method for storing vibrational data of the same
Inventor: SASAKI YUICHI
IPC: G01H1/00
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent a handy type vibration meter with built-in detector from being affected by shaking when the meter is manually operated when vibrations are measured. SOLUTION: In a vibration meter 1, analog signals from a detector 11 are stored in the RAM 10c of a storing section 10 after the data are converted into digital signals. In measurement, the digital signals received during a fixed period of time until now and always stored. When a measurer stores the digital data as vibrational data by operating the meter 1, the measurer presses a storage switch 14a. When the switch 14a is pressed, an MPU 10a selects the digital signal stored before the switch 14a is pressed from the stored digital signals and stores the selected data in the RM 10c as the vibrational data. Therefore, the stored vibrational data do not contain the digital signal stored when the switch 14a is pressed and, even when the meter 1 is shaken by hand when the switch 14a is pressed, the stored data are not affected.

Filed: 1985-09-02
Abstract: PURPOSE:To provide an HBT unsaturated type circuit which facilitates higher speed switching operation by a method wherein a resistor is added to the emitter side of a switching transistor to obtain a larger current density in the OFF state and hence the charging time of the emitter is shortened. CONSTITUTION:Resistors 12a and 12b on the emitter sides of switching transistors 10a and 10b are formed by evaporating NiCr alloy or the like into circuit patterns. The resistance value is determined in accordance with the V-I curve of the transistor, In other words, a curve (2), which is obtained by plotting the points, which are determined by adding voltage drop values ICR, induced when a suitable resistance R is added to the transistor, to the voltage values VBE of a VBE-IC curve (1) of the transistor. Then it is confirmed whether the charging time of the emitter, estimated from the figure, corresponding to the current density in the OFF state, is sufficiently small or not. If the time is not sufficiently small, the value of the resistance R is changed and the same process is repeated. Practically, it is recommended to perform this process by numerical processing.

Abstract: PURPOSE:To protect a GTO and a MOSFET from destruction by detecting a current of the MOSFET, raising a turn-on stop signal when the rate of increase is nearly zero and stopping the trigger of the GTO at the next cycle. CONSTITUTION:A drain current detector 9 provided in series with the MOSFET 6 detects a current and sends the value to a waveform processing section 10 having a differentiation circuit and an integration circuit.

The processed electric quantity is sent to a comparison circuit 11, where the electric quantity from a reference power supply 12 having an electric quantity corresponding to the capability limit of the MOSFET 6 is compared with the processed electric quantity. When the electric quantity from the processing section 10 is the same as or larger than the reference value, a signal is sent from a pulse forming section 13 to a turn-on pulse generator 14 to stop the on-pulse from the next cycle. Thus, the destruction of the GTO1 and the FET 6 is protected.
