Patent JP-H0729943-A (JP)
Title: Wire bonding method
Inventor: SATO HIDEAKI
IPC: H01L21/607
Filed: 1993-07-13
Abstract: PURPOSE:To ensure necessary connection strength and isolation distance between metal thin wires. CONSTITUTION:While a metal thin wire 2 is sequentially led out from a capillary 1, the first part of the metal thin wire 2 is connected with an electrode pad 4, the second part of the metal thin wire 2 is connected to a portion within 150mum away from the end of an outer lead terminal 5 by thermocompression bonding, the capillary 1 is moved to the position spaced 400mum or more from the tip of the outer lead terminal 5, and the third part of the metal thin wire 2 is connected with the position, by thermocompression bonding using ultrasonic waves. When ultrasonic vibration is applied, the metal thin wire 2 is rotated, the distances between the metal thin wires 2 become insufficient, so that the ultrasonic vibration is also used after the rotation of the metal thin wire 2 is stopped by thermocompression bonding. Thereby necessary connection strength and distance are ensured. In paticular, the above method is useful in the case of 5 or more metal thin wires 5 or in cases where the longitudinal direction of the outer lead terminal 5 is inclined to the extention direction of the metal thin wire 2 in a semiconductor device of high density wiring.

Title: Building frame for stacking in order
Inventor: KADANI TOSHIO
IPC: E04G1/14
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To stack building frames mutually in order by providing side pipe materials with projections to prevent lateral shifting of an upper adjacent building frame of the same shape and the size stacked on the building frame placed in the horizontal state. SOLUTION: This building frame is formed by providing a pair of right and left side pipe materials 1, 1 and a lateral pipe material 2 for connecting the pipe materials 1, 1 to each other. A support shaft 4 to which a reinforcing material 3 and a brace member are fitted is provided between the side pipe material 1 and the lateral pipe material 2. Further, to prevent lateral shifting of an upper adjacent building frame to be stacked, a projection 5 is fitted to the side pipe material 1. As a stopper of the upper adjacent building frame guided by the projection 5 to be slid in the longitudinal direction, a projection 6 is provided on a part a little to the outside of the center. Thus, mutual longitudinal shifting of upper and lower building frames to be stacked each other is restrained.  Thus, even if many frames are stacked upward, the center of gravity of each building frame is positioned in the same vertical central plane in the longitudinal direction, so that stability can be ensured.

Title: Premix forced ignition combustion method for diesel engine
Inventor: ISHIDA HIROYUKI
IPC: F02D41/40
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent self-ignition before normal ignition by injecting main fuel several times apart in a premix forced ignition combustion method for a diesel engine. SOLUTION: In a stroke of a piston 2 starting to ascend from -180 deg. (bottom dead center) and starting compression, fuel 11a is injected four times in division. The injection period is between -180 deg. and slightly over -90 deg.. In this stroke, pressure in a cylinder 1 is low, and when the fuel is injected, the fuel is scattered. When scattering becomes excessive, the fuel adheres to the internal wall of the cylinder 1, and the formation of a mixture is nonuniform, but the scatter and adhesion of fuel to the internal wall of the cylinder 1 are prevented by injecting fuel several times apart. Since air 10a agitates the injected fuel, the mixture becomes uniform so as to eliminate self-ignition heretofore generated by the high concentration part of fuel.

Filed: 1988-07-12
Abstract: PURPOSE:To improve driving efficiency by using the diametrically secondary and circumferentially tertiary flexural oscillation so an oscillation mode and by making the thickness of an oscillating body thin right around a rotating shaft. CONSTITUTION:An ultrasonic motor constitutes an oscillating body 10 by sticking a piezoelectric body 8 to one of the main surfaces of a discshaped elastic body 7 and to the other surfaces projected bodies 9 for taking out mechanical output are formed. A moving body 13 is constituted by sticking a friction material 11 made of wear-proof material to the elastic body each other, with which the above projected body 9 is pressurized and brought into contact.

Title: Digital temperature compensation crystal
Inventor: ITO KUNITA
IPC: H03B5/32
Filed: 1986-07-22
Abstract: PURPOSE:To obtain a digital signal directly without needing an A/D converter by using a signal of a frequency division section passing between output pulse widths of a monostable multivibrator as temperature information so as to eliminate the need for the synchronization between a clock signal and a temperature information signal. CONSTITUTION:An output signal of an oscillation section 1 is frequencydivided by a frequency division section 2 and inputted to a gate circuit 3. A temperature signal from the oscillation section 1 enters a monostable multivibrator 4 and a pulse having a width corresponding to the temperature is inputted to a gate circuit 3. An output of the gate circuit is counted by a counter 5, inutted to a ROM 6 storing the temperature characteristic of a crystal vibrator and a frequency control signal corresponding to the temperature is outputted. A latch circuit 7 is a storage circuit storing temporarily the signal from the ROM 6 and cleared at a prescribed time by a signal from the timing circuit 8. Since the frequency control signal is a digital signal, it is converted into an analog signal by a D/A converter 9, the result is inputted to the oscillator 1 thereby controlling the frequency and obtianing stable frequency.
