Title: Laser welding method
Inventor: KIMURA SEIICHIROU
IPC: B23K26/21
Filed: 1983-04-05
Abstract: PURPOSE:To perform welding with less thermal influence in welding from one side by forming holes or groove-like cavities in an object to be welded on the incident side of laser light and introducing the laser light therein. CONSTITUTION:A crank 11 is inserted int the prescribed position of a pipe- shaped shaft 10 and is maintained in the specified position by means of a jig. Holes 12 having about 1mm. diameter are formed as cavities at two points of the crank 11 throghout the thin-walled part thereof. The jig or the irradiating side of laser light 14 is relatively moved to introduce the light 14 into one hole 12. The light 14 introduced therein melts the shaft 10 and the thin-walled part of the crank 11 is also melted by the temp. of the melt, by which the two members are welded. The other hole 12 is subjected to the similar welding. Bending of the shaft 10 to the welding side by a thermal influence is obviated by the above- mentioned method.

Title: Pulse detection circuit
IPC: H03K5/01
Filed: 1992-03-17
Abstract: PURPOSE:To attain excellent tracking by comparing output levels of an amplifier circuit and varying each setting amplification factor so as to adjust the signal level. CONSTITUTION:An amplitude of a very small amplitude input signal S1 is amplified by a variable amplifier circuit 11, and an amplitude of a true signal component reaches a saturation level and an amplified signal whose noise amplitude is 2V is obtained. Since an upper limit comparison signal pulse SU is outputted to the circuit 11, a setting amplification factor of the circuit 11 changes to 35dB. Then the amplified signal is changed into the amplified signal in which the true signal component amplitude is 1.125V and the noise amplitude is 0.355V. Then an analog level of the amplified signal is compared with a reference level being 1V at a comparator circuit 2, in which the input analog level is converted into a logic level (level '1'=5V and level '0'=0V) depending on the quantity with respect to the reference level and a detection signal SD is obtained and only a true signal component is detected. Thus, excellent tracking is attained.

And, a silicate glass layer 3 is formed on the whole surface of the substrate 1. Then, the substrate 1 is heated, and As impurity is diffused from the layer 8 into the polycrystalline silicon layer which constitutes the electrodes 51 and 71. But the As impurity is not diffused into the layer 61. Therefore, the layer 61 is excellently uniform in thickness, and the capacitance between the electrodes 51 and 71 is made to decrease in dispersion.

Title: Magnetic measuring instrument
Inventor: SHINOMURA KAZUYA
IPC: G01R33/26
Filed: 1979-05-15
Abstract: PURPOSE: To increase precision and sensitivity by improving the fault that an error is easily generated, by composing a magnetic measuring instrument of a photo- magnetic resonance magnetometer, frequency multiplier, counter, gate generator, display unit, D/A converter and recorder.  
     CONSTITUTION: While the feature of photo-magnetic resonance magnetometer 9, i.e., high sensitivity, is not lost, the oscillation frequency of magnetometer 9 is multiplied by about 800 by frequency multiplier 10 to increase resolution. Then, counter 11 counts the number of pulses. A count gate sent from gate generator 13 exercises control over how long counter 11 counts and the gate time should be made variable. The output of counter 11 is sent to digital display unit 12 to display the absolute value of the intensity of an ambient magnetic field. Another output of counter 11 is a low-order digit output and is transformed by D/A converter 14 into an analog voltage, which is sent to recorder 15 to display only the variation of the intensity of the ambient magnetic field with high sensitivity. Here, adjusting the time width of the counting gate generated by generator 13 makes it possible to correct the frequency error or magnetometer 9.

Title: Geotherm take out device
Inventor: SAKAMOTO SANZO
IPC: F24J3/08
Filed: 1992-02-13
Abstract: PURPOSE:To maintain constant temperature and humidity of an air in a heating medium, use geothermal sources and reduce air conditioning cost by discharging ground water by way of a pipe, transmitting the heat of the ground water to the heating medium by way of the pipe, passing and emitting the air through the heating medium. CONSTITUTION:A geothermal take out device 17 uses a drain device 12 which discharges ground water outside by way of an under water flow-in pipe 3. The heat of the ground water is transmitted to a heating medium 4 by way of the ground water flow-in pipe 3, thereby maintaining the heating medium 4 at a constant temperature. On the other hand, the air is introduced into the lower part of a pressure tank 1 from an air nozzle 5 by driving an air compressor 8. After having passed through the heating medium, the compressed air is emitted from an air blow off port 11 by way of an exhaust duct 10. As a result, the temperature of the air is maintained at a constant value while its humidity is also maintained at a constant value. This construction makes it possible to maintain the temperature and humidity of the air at a constant value by using the geothermal sources, thereby performing cooking in summer or heating and removing snow in winter with simplicity and at low cost.

IPC: B23K26/21
Filed: 1993-03-19
Abstract: PURPOSE:To form a constantly excellent weld bead even when the sectional area of the joint is changed by obtaining the sectional area of the joint shape from the joint shape recognizing data obtained by a shape recognizing sensor, and changing the welding current or the welding speed according to the change in the sectional area. CONSTITUTION:The shape of the groove and the position are recognized by a shape recognizing sensor 10 in order to form the uniform weld bead over the whole circumference and to obtain the excellent weld by producing the same shape of the upper and lower beads, and the control is realized to set a welding electrode 6 to the prescribed position. The sectional area of the groove is obtained from the data obtained by the shape recognizing sensor 10, and the welding condition is changed thereby. For example, when the sectional area is increased, the amount of the filler metal necessary to fill the section is increased. When the speed to supply the filler metal of an automatic welding machine to be used is constant, the amount of the filler metal to be supplied per unit sectional area of the groove is increased if the welding speed is reduced.
