Title: Simplified mobile truck for welding
Inventor: KODE TOMOJI
IPC: B23K37/02
Filed: 1984-12-14
Abstract: PURPOSE:To enable the travelling back and forth and to cope easily with the reciprocating and continuous welding or reducing measures for unfinished welding by making the welding line side of a truck a driven wheel and by making the slidable range more than the height of the arc obtd. from a turning angle. CONSTITUTION:The non-travelling side of a truck 1 is made a driving wheel 7 and the welding line side a driven wheel 8 at its travelling time. The turning angle of an axle 9-2 is theta at the travelling time and the driven axle 8-2 is controlled inn its sliding by the stopper part being provided on the tip of the axle 9-2. When the truck 1 is moved reversely, the axis 10-2 of the driving wheel 7 is moved to the position 10-1, and to the position 10-3. The driven wheel 8 changes its course with turning by the axle 9 in the state of its stoppage. The driven wheel 8 slides more than the height >= of the arc obtd. by the distance between the axis 10 of the case of the tuning angle theta and the driven wheel 8 and the load to be followed by the course change is not transmitted to the truck 1. A stabilized profiling travelling is obtd. with the action of the component force due to the changed movement into the welding line direction on the longitudinal plate member after the two theta course change of the driven wheel 8.

Title: Ray type sensor
Inventor: WADA TAKETSUGU
IPC: G01S7/481
Filed: 1985-11-25
Abstract: PURPOSE:To obviate the change of light power even if the focal length of a plastic lens changes with ambient temp. by providing a diffusion plate which receives the light from a light receiving element with the rear surface and transmits light to the plastic lens from the front surface as a uniform surface light source. CONSTITUTION:The diffusion plate 3 is installed between the lens 1 and the light emitting element 2. Said light receives the light generated like a spot from the element 2 on the rear surface and transmits the light to the lens 1 from the front surface as the uniform surface light source. The diffusion plate 3 is formed of, for example, ground glass, white plastic plate or bubble lens plate of which the front surface is worked to a special shape so as to uniformly diffuse light. Since the light from the element 2 which is point light emission is emitted as panel light by the diffusion plate 3, change of the opening angle betaby the deviation in the focal position of the lens is extremely small even if the focal position of the lens deviates to F1 or F3. The plastic lens is, therefore, so constructed that the light power outputted therefrom does not change in spite of a change of the focal length thereof by the ambient temp. The ray type sensor having high measurement accuracy is thus obtd.

When a threshold voltage at the read time is higher than a predetermined value, it is judged as a second abnormality. At the occurrence of such abnormality, a control circuit 4 stores an address and a bit number to a second memory device 5. When an address of a memory matrix 1 of a nonvolatile memory transistor required to read stored data agrees with the address stored in the second memory device 5, the control circuit 4 outputs data corresponding to a high threshold value in the case of the first abnormality, and data corresponding to a low threshold value in the case of the second abnormality to the read means 3.

Abstract: PURPOSE:To attain the control of the states of a recording/reproducing system and to simplify the circuit constitution and the control process of a magnetic recording/ reproducing device, by recording two different signals on a medium with overlap and detecting the recording depth of one of both signals from the erasion factor of the other signal. CONSTITUTION:The signal of 1.5MHz sent from an osicillator 4 is supplied to a head 6 via a switch 3 and an adder 2 and recorded on a tape 7 in a non-input state of the recording signal. This recorded signal is reproduced by a head 8 and the signal of 1.5MHz is extracted by a BPF 13. This extracted signal is stored in a memory 17 by a CPU 16 after wave detection 14 and A/D conversion 15. Then a switch 3 is opened and the luminance signal is recorded with overlap in the recording place of the 1.5MHz signal of the tape 7 via an adder 2 and the head 6. The signal of the tape 7 is reproduced and the 1.5MHz signal is extracted again by the BPF 13 to be stored in a prescribed area of the memory 17 after wave detection 14 and A/D conversion 15. The CPU 16 reads each value out of the memory 17 to obtain the rations among these values and detects the recording depth from the surface of the tape 7 for the luminance signal to convert the detected information into the prescribed control information.
