Filed: 1994-05-26
Abstract: PURPOSE:To prevent occurrence of the recess of bead and pinhole by avoiding the heat concentration in the welding of the R-part of a molding by rapidly moving a torch, executing no extinction of arc on the molding surface, and avoiding the heat concentration at the R-part of other molding. CONSTITUTION:The molding is required to be welded so that the bead may not be recessed and no pinholes may be left. A plasma torch A realizes the arc ignition at the position 8. The plasma arc 14 also welds the side of a work 4 at the same time. Then the torch reaches the position 10 along the work, and heats and welds the side of the molding. The torch is advanced to the position 11 with its speed reduced, and at the position 11, the arc is forcibly extinguished. Then, the torch is advanced to the position 12 without any load, and there, the arc is ignited. At the position 13, the arc is extinguished to complete the welding. Because the movement of the torch is simple, the teaching can be easily realized when the welding is made by a robot, etc., and the working time is reduced compared with the divided welding method.

Title: Semiconductor pressure sensor device
Inventor: YOSHIDA HIROSHI
IPC: G01L9/04
Filed: 1979-09-05
Abstract: PURPOSE:To obtain an equal or higher conversion efficiency at a thin semiconductor substrate in a semiconductor pressure sensor device even if a thick substrate is used by forming a diffused resistance layer on each of both sides of the substrate. CONSTITUTION:Resistance layers 11, 12 are formed by diffusion of impurity of reverse conductivity type to one conductivity type Si substrate 1 along the upper and lower surfaces of the substrate 1. In this case, the layers 11, 12 are so formed as to become symmetrical on both side surfaces of the substrate 1. Further, the lower side of the substrate 1 is adhered with an insulating pedestal 14 having a recess, and the space 15 formed with the recess of the pedestal 14 and the substrate 1 is evacuated into vacuum. When pressure is applied to a pressure sensor thus formed, the substrate 1 is warped due to the pressure difference between the chamber 15 and the sensor, the upper surface of the substrate is contracted, while the lower surface thereof is extended. Accordingly, the layer 11 is reduced in resistance, and the layer 12 is increased in resistance. That is, since the layers 11, 12 vary in resistance values reversely to each other against the pressure change, they equivalently vary double. Accordingly, when their efficiencies are equal, the substrate can be increased in thickness to approx. double by combining the rsistances of the upper and the lower surfaces thereof.

Title: Liquid fuel combustion equipment
Inventor: MAEHARA NAOYOSHI
IPC: F23N1/02
Filed: 1980-08-18
Abstract: PURPOSE: To realize the clean combustion in a compact structure by a method wherein a means, which enables to control the combustion rate while the combustion characteristics is kept all the time as good as that of vaporizing type oil burner, is provided in the combustion equipment for the liquid fuel such as kerosene or the like.  
     CONSTITUTION: When the maximum air flow is sensed by an air flow sensor 31 after the start of a convection fan 2 and a combustion fan 22, a timer 35 gives a command after the elapse of the fixed time to an atomizing rate control unit 33 to start the supply of alternating power to a piezo-oscillator 18 and the transfer to the ignition operation is completed. When a positive voltage is applied to the piezo-oscillator 18, the oscillator 18 contracts to produce a deflection with a supporting part 18 as a fulcrum in the direction to ward a nozzle 14 and pressure waves are generated within the kerosene confined in the cavity of the oscillator 18 so that the pressure in the kerosene reaches very high near the nozzle 14, resulting in vomitting the kerosene from the nozzle 14. When a negative voltage is applied to the piezo-oscillator 18, the oscillator 18 expands to produce a deflection in the direction opposite to that occured at the application of a positive voltage, resulting in producing the fluidic diode action to lower the pressure of the kerosene near a vibrating plate 17. As a result, due to the manner as discribed above, the suction pump like action is established for the supply of the kerosene and the combustion performance similar to that of vaporizing type burner is obtained for the atomization of the kerosene.

Title: Skid control device
Inventor: MATSUMURA AKIRA
IPC: B60T8/66
Filed: 1979-09-07
Abstract: PURPOSE: To control a speed signal to be close to an actual speed of a car to obtain an appropriate value by switching time and speed into the time and the decelerated speed which are set in advance in case of a speed pulse failure.  
     CONSTITUTION: When speed pulses are failed to be generated for longer than a set time of retriggerable monostable multi vibrator (RMMV) 15, its output Q becomes "0". As the result, an output Q from a timer 16 starts timing, and the output Q during the set time becomes "0" to connect a transistor 17, and an unreversed input voltage of an amplifier 18 is decreased to reduce a car speed signal output at deceleration which is smaller than that of initial deceleration. After a set time of the timer 16, the transistor 17 is shut off, and the deceleration of the car speed signal output becomes the initial deceleration. Therefore, when generation of car speed pulses is failed, the car speed signal shows the value close to the actual speed, and the safety can be increased.
