Title: Method for preventing high-temperature cracking of energy beam welding
Inventor: KAMITO YOSHIMI
IPC: B23K15/00
Filed: 1987-12-24
Abstract: PURPOSE:To always obtain a stable penetration bead shape and to prevent the occurrence of weld defects by changing a convergent lens current according to the change of an energy beam current even if it is changed to execute control so as to maintain the focus position constant. CONSTITUTION:At the time of executing crater treatment by controlling the convergent lens current of a crater treatment part, the rated beam current is reduced in a straight line. At this time, when the convergent lens current is constant, the focal distance is lengthened and the focus position is changed as the beam current decreases. Then, the current of a convergent lens coil incorporated in an electron gun 5 is controlled in accordance with the beam current so that the focus position 11 is subsequently made to the position of the same depth (d) even at a crater treatment slope-down part. By this method, the bead shape 7' is made to a wedge type and made to the same extending over the whole weld line and the high-temperature cracking due to the bead shape change can be prevented.

Abstract: PURPOSE:To reliably measure the intensity of light which irradiates a body to be processed by providing a perforation on a placing table where the body to be processed is placed and measuring the intensity of the light passing through the perforation. CONSTITUTION:The placing table 3 where the body 14 to be processed is placed and which is provided with a hole 25 and a sensor 26 which measures the intensity of the light of a light source passing through the hole 25 of the table 3 are provided.

Title: Transmitter for remote control
Inventor: WATANABE YOSHIHIKO
IPC: H04B1/034
Filed: 1992-11-13
Abstract: PURPOSE:To improve the easiness and safety of control by moving the transmitter itself in the desired direction of moving a machine body. CONSTITUTION:When a transmitter 1 is moved at a certain angle in a certain direction, this movement is detected and a signal is outputted by a posture detecting means composed of inclinometers 2 and 3 and a gyroscopic azimuth gauge 4. This signal is turned to a steering signal for commanding a steering direction and a steering amount corresponding to the angle. Thus, the machine body changes the posture in the same direction at the same degree as the transmitter 1 while following up the movement of the transmitter 1. Therefore, since it is enough for an operator only to incline the machine body just for that amount in that direction when it is desired to incline the machine body, the control is exactly performed with extremely simple operations.

Title: Oxygen concentration controller
Inventor: OYAMA TAKASHIGE
IPC: F02D41/14
Filed: 1995-12-18
Abstract: PURPOSE: To prevent erroneous operation of a control system due to an output signal from an oxygen concentration detector by stopping the closed loop control or the current control for a solid state catalyst in a region where the excess air rate of a gas to be detected is equal to 1 or below. CONSTITUTION: Under a state where the excess air rate λ of a gas to be measured is lower than 1, a current is generated due to electronic conduction and thereby the current control is stopped to keep the level of current I flowing through an electrolyte 1 at O. When a state of λ>1 is set, the operation is started while keeping the output voltage from a voltage detector 3 at a constant level. When the outside partial pressure PM of a diffused resistor 6 drops to cause lowering of λ, the partial pressure PV of oxygen in a chamber 5 drops to cause increase in the voltage V. On the other hand, when the partial pressure PM increases, the partial pressure PV also increases to cause lowering of the voltage V.  When λ<1, erroneous operation of the control system can be prevented through closed loop control of fuel, air flow controller or through closed loop control with negative current I. The current 1 is set positive at the time of transition from a state where λ<=1 to a state where λ>1.

Abstract: PURPOSE:To obtain a convenient efficient and inexpensive device by using a gauge plate to form a reference crossing pattern with a light shielding property on the surface of the light shielding property plate material and detecting the light to leak from the reference crossing pattern. CONSTITUTION:When the optical scanning is executed by a hologram scanner 1, a light crossing pattern SP is drawn on the surface of a scanning stand 2. When the crossing pattern SP is in the area of a reference (light shielding) crossing pattern BP' of a gage plate 4, light leakage does not occur. Consequently, a light detecting means 5 does not output, the laser optical scanning position of the scanner 1, namely, the light crossing pattern SP is decided to be good. Reversely, when the light crossing pattern SP is positioned outside the area of the reference (light shielding) crossing pattern BP' of the gage plate 4, the light leakage occurs. Consequently, a light detecting means 5 detects and displays it, and the laser light scanning position of the scanner 1, namely, the light crossing pattern SP is decided to be bad.
