Title: Method for detection of the position and geometry of work piece surfaces
IPC: B23K9/12
Filed: 1986-08-27
Abstract: To detect the position and geometry of workpiece surfaces, in particular welded joints in automatic arc welding, the workpiece surface, or preferably a section thereof, is imaged from two different viewing points on two image pick-up devices so that mutually displaced images of the workpiece surface are imaged on the two image pick-up devices, and the position and spacing of the prominent points on the workpiece surface on the two image pick-up devices are used to calculate the position of said prominent points in the spatial coordinate system of the measuring device so that the geometry of the workpiece surface and its position with respect to the observing system can then be determined from the position of all the calculated points. <IMAGE>
Patent EP-0236721-A3 (EP)
IPC: B25D9/12
Filed: 1987-02-02
Abstract: It is so arranged in the hydraulic breaker according to the 
present invention that the oil pressure at a fixed value is al­
ways flown in the circuit at low pressure side whenever the 
piston is raised or lowered, thereby to dispense with an ac­
cumulator in the circuit at the low pressure side, and at the 
same time, a quantity of the high pressure oil is required in 
any of the rising and falling processes of the piston, with 
bringing about less change in the surge pressure, resulting in 
no necessity for an accumulator to be provided in the circuit 
at the high pressure side. Moreover, the hydraulic breaker of 
the present invention is advantageous in increased striking 
force because the high pressure oil is made use of, in addition 
to the reaction force of the compressed nitrogen gas, when 
the piston is lowered to strike the chisel.

Patent EP-0247383-A3 (EP)
IPC: G06F7/52
Filed: 1987-04-30
Abstract: In a high-speed arithmetic processor (30), a first number 
that has an absolute value that can exceed one is multiplied 
by a second number that has an absolute value not exceeding 
one. If the first number exceeds one it is divided into 
an integer and a part having a value less than one. The 
second number is accumulated as an addend a number of 
times equal to the integer to produce a sum. The second 
number and the part of the first number having a value 
less than one are supplied to a multiplier (43) to produce 
a partial product. An adder (45) adds the partial product 
to the sum, thereby obtaining a final product of the 
first and second numbers. The multiplication is thereby 
performed in a number of steps which is minimized and 
never varies, regardless of whether the absolute value 
of the first number is, for example, less than one, at 
least one but less than two, or at least two but less 
than three. This speeds up the arithmetic processing 
and simplifies the programming therefor.
Patent EP-0250985-A3 (EP)
IPC: H01J29/89
Filed: 1987-06-12
Abstract: A flushing system is provided for a light 
valve of the Schlieren dark field type. A small 
amount of filtered fluid is injected into the 
space between the rotating disc and the output 
window of the light valve. This is done by 
injecting the fluid through the center disc 
bearing, thereby providing a uniform radial flow 
outwardly from the center and flushing out any 
particles in the space and preventing any 
particles in the surrounding fluid from moving 
into the raster area. By properly regulating the 
flow of the center flush fluid, the disc can be 
floated off the support during rotation. This 
reduces wear generated particles which contribute 
to substrate buildup and subsequent loss of light 
throughput. In addition, erratic disc motion 
caused by a stick and slip frictional effect is 
reduced.

Title: Method of producing an optical recording card and transfer type optical recording medium
IPC: G06K19/08
Filed: 1987-06-17
Abstract: An optical recording card is produced using a transfer type optical recording medium. The transfer type optical recording medium comprises a base film, a peeling layer, an optical recording layer and a light pearmeable adhesive layer which are successively superimposed one above another to constitute a layered structure. A protective layer is adhered to the transfer type optical recording medium with the aid of an adhesive layer and the base film is then peeled off together with the peeling layer. Next, the protective layer to which the optical recording layer is adhered is adhesively attached to a card base in such a manner that the optical recording layer is interposed therebetween whereby an optical recording card is completely produced. The transfer type recording medium can be preserved in such a state that it is wound about a reel. Accordingly, the transfer type recording medium is adhered to the protective layer when the optical recording card is produced, and thereafter it is adhered to the card base. Thus, the optical recording card can be produced at a high productive efficiency.

Title: Digital lock-in amplifier
IPC: H03D1/22
Filed: 1988-09-30
Abstract: An analog input signal (Sin) is converted into a digital 
signal. The digital signal is shifted to the difference 
frequency region by mixing it (24, 25) with each of a sine wave 
local signal (26) and a cosine wave local signal (27) to obtain 
complex waveform data. On the other hand, a trigger signal (T) 
is generated when a reference signal (Sr) meets a specific 
requirement, and a frame composed of a fixed number of 
data is defined which is synchronized with the trigger 
signal (T). The complex waveform data of each frame thus 
defined is phase rotated (38) so that its phase angle has a 
predetermined value, or the phases of the local signals 
are synchronized with the trigger signal so that the complex 
waveform data of respective frames have the same phase. 
Besides, the in-phase complex waveform data of plural 
frames thus obtained may also be averaged (40), if necessary.

Filed: 1988-04-08
Abstract: A time base corrector converts an analog input PAL image signal 
including a certain time base error into digital form and then stores 
it in a memory (13) by using a write clock signal derived from the 
input PAL image signal including the time base error. The stored 
signal is read out from the memory (13) by a reference readout clock 
signal to eliminate the time base error, and a reference colour burst 
signal is added to it in an adder (22). The time base corrector 
extracts a colour subcarrier signal (C′) from the input PAL image 
signal by means of a low pass filter (2), samples the colour 
subcarrier signal by using a first clock signal (CK) in a manner such 
that U-axis data and V-axis data of the colour subcarrier signal are 
generated independently of each other, compares by means of an 
exclusive -OR gate (19) the polarity of the V-axis data of the colour 
burst of the sampled colour subcarrier signal with the polarity of the 
V-axis data of the reference colour burst signal, and selectively 
inverts in a V-axis inverting circuit (18) the polarity of the V-axis 
data of the colour burst of the sampled colour subcarrier signal on 
the basis of the comparison result.
