Title: Control method of tool for working machine
Inventor: JIYABUAADO HOTSUSEINII
IPC: E02F3/43
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To smoothly and gradually stop tools. SOLUTION: Tools 102 are connected to a construction machine 104 and made movable between the first and second tools positions in accordance with actuation of a hydraulic actuator 106. A device 100 has a joy stick containing the first and the second stop positions and the neutral position. The joy stick is usually set in the neutral position and made movable between the first and the second stop positions. The device detects the position of joy stick and generates the positional signal of the joy stick according to the detected position. When the joy stick is moved to the first or the second stop positions manually, it is kept in the position. When release signals against stop signals are received, it is released from the stop position. The device detects the positions of working tools against the construction machine.  The device provides the stream of hydraulic fluid to the hydraulic actuator 106 in accordance with the magnitude of electric valve signals. The device receives the positional signals of joy stick and transmits electric valve signals proportional to the signals. The positional signals for tools are compared with the first and the second stop positions to output release signals against stop in accordance therewith.

IPC: H05K3/34
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a simple method of high reliability which is used for forming a solder ball contact on a contact grid array provided at high density. SOLUTION: Solder paste is squeegeed on a pad on a substrate 11 through an aperture of a fixture 15. The fixture, the solder paste and the substrate are heated. The solder paste is subjected to reflow to a solder ball 41 which is bonded to the pad and repelled from the fixture. Thereby the solder ball is formed. After cooling, the fixture is separated from the substrate, and the solder ball is left in the state that it is in conductive contact with a contact pad on the substrate.

Title: Seniconductor laser
Inventor: IWATA HIROSHI
IPC: H01S5/00
Filed: 1986-11-27
Abstract: PURPOSE:To inject carriers effectively to a quantum well fine line, and to obtain a semiconductor laser having a small oscillation threshold by making the potential energy of a first quantum barrier region higher than the quantum well fine line, making the potential energy of a second quantum barrier layer higher than the first quantum barrier layer and using the quantum well fine line as a main light-emitting region. CONSTITUTION:Holes and electrons each injected from a P electrode 18 and an N electrode 19 are injected into a first quantum barrier region 14 from second quantum barrier layers 13a, 13b, and confined into the first quantum barrier region 14, but they flow into quantum well fine lines 15 because the potential energy of the quantum well fine lines 15 is low. Since both holes and electrons are confined in two dimensions and brought to the false one- dimensional state in the quantum well fine lines 15, each density of the states is concentrated into narrow energy regions, and the recombination spectra are narrowed extremely. Accordingly, all carriers effectively contribute to laser oscillation, thus acquiring a semiconductor laser having extremely small oscillation threshold currents.

Title: Liquid fuel burner
Inventor: TOMITA HIDEO
IPC: F23D11/24
Filed: 1985-12-17
Abstract: PURPOSE:To mix with a relatively small amount of turbulence the air jetted out of an air hole and a vaporized fuel and reduce combustion noises due to pressure variation by opening an air hole for flow swivelling on the upper section of the outer circumferential face of a carburetor cylinder and further providing a circular air hole under that air hole for flow swivelling. CONSTITUTION:On the upper section of the outer circumferential face of a carburetor cylinder 4 which has its upper end closed and has a cylindrical shape an air hole 5 for flow swivelling is opened which points substantially in tangential direction to the carburetor cylinder. Further, below those air holes 5 for flow swivelling circular air holes 5a are opened. The air sent into the carburetor cylinder 4 jets out from the air holes 5 for flow swivelling and the air holes 5a to form a swivelling flow 19 in the upper section of a carburetor chamber 1. At the same time the air is pressurized by an electro-magnetic pump 15 and atomized at a nozzle 11. The atomized oil and the air are thereby mixed and ignited. The mixture of the vaporized fuel and the air jetted out of the air holes 5a does not collide with the swivelling flow, so that it has relatively little disturbance in the mixing, giving little variation in the generated heat quantity in the combustion reaction.

Title: Optical image reader
Inventor: JINBO NORIYUKI
IPC: G03B27/52
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To provide an optical image reader which can scan a manuscript with high precision by setting the optimum driving torque, in accordance with a necessary scanning speed. SOLUTION: This optical image reader optically reads a manuscript by moving a scanner at a specific scanning speed with a pulse-controlled stepping motor 36. When the manuscript is scanned, an exciting signal forming circuit 202 generates an exciting signal as the base, which corresponds to a set speed and outputs it to each AND circuit 204. From a current/PWM control circuit 205, a microstep-forming circuit 203 obtains the number of divided steps of microstep, the maximum drive current, and percentage data to the maximum drive current in each step, determines the number of times for the generation of on clock signals in each divided step period, outputs the number to the AND circuits 204, and performs the microstep drive.  The smaller the scanning speed is, the smaller the maximum driving current will be set, so that the rotating operation of low vibration can be obtained, while the balance of the load torque and the drive torque is maintained. Thereby an optical image reader of high reading precision can be obtained.

Title: Pulse width modulation method for power converter equipment
Inventor: LEE GEUN HOO
IPC: H02M7/12
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To reduce substantial switching loss by performing pulse width modulation by comparing a voltage and a frequency supplied to a load to predetermined values and by stopping the switching of a phase having the largest value of a phase current in a small section. SOLUTION: By considering phase θ of voltage, a process of reversely converting each output voltage Vqe, Vde of rotatory coordinate system to a plurality of phase voltage commands Vas- r, Vbs- r and Vcs- r of stationary coordinate system is performed (ST1). Next, the size of voltage and frequency are judged from each output voltage Vqr, Vde and compared to already set predetermined values (ST2). These predetermined values are reference for performing three-phase pulse modulation or two-phase pulse modulation. If the size of voltage and frequency is smaller than the predetermined values already set, then three-phase pulse width modulation is performed by the higher harmonics of current. That is. three-phase or two-phase pulse width modulation can be performed selectively by the voltage and frequency of a motor, and the switching loss can be reduced.
