Filed: 1981-09-18
Abstract: PURPOSE:To elevate reliability of seam welding without exerting bad influence on a metallic structure of a substance to be welded, by providing a reflection body on a rocking member provided on the upper position of an upper chip for pressing the substance to be welded, and reflecting a laser light downward. CONSTITUTION:On a receiving base part 8b of a lower chip 8 of a welder, a substance to be weled 9 is placed. A rocking lever 5 is turned counterclockwise, and the substance to be welded 15 is pressed and fixed by an upper chip 5. Subsequently, a reflection body 25 installd to a rocking member 24 is rock-operated slowly by simultaneously driving a driving motor 21 and a laser device. In this case, the laser light is reflected downward by the reflection body 25, and executes seam welding of constant bead length to a weld zone 9a through a condensing lens 26. In this case, even if there is a slight difference in thickness of the substance to be welded 9, the lower chip 8 moves round the supporting axis, and smoothly presses the substance to be welded 9.

Title: Voltage correction system in alternating-current control
Inventor: MUKAI KUNIAKI
IPC: G05F1/455
Filed: 1980-10-21
Abstract: PURPOSE:To suppress transient variations in current low by calculating a corrected ignition angle DELTAalpha for a predetermined load power factor phi, ignition angle alpha, and power voltage deviation DELTAV, and by storing it in a memory in the form of a function of the DELTAV, alpha, and phi. CONSTITUTION:A voltage deviation detection part 10 detects the voltage variations of a power source 5 in every half cycle to output a DELTAV, and a function f(DELTAV)  stored in a memory 11 is read out and inputted to a multiplying circuit 15. On the  other hand, a circuit 12 which measures and stores a current lagging angle theta stores  the theta of an ignition angle 90 deg. right after the starting of operation, and it is used as the address of a memory 13 storing a theta-to-phi function to read a power factor phi from the memory 13, thereby inputting it to a memory 14. An ignition angle is inputted from a control system to the memory 14 to output a function f(alpha, phi), which is inputted to a circuit. The circuit 15 outputs the corrected ignition angle DELTAalpha of an f(DELTAV)Xf(alpha, phi), which is multiplied by a coefficient at a coefficient circuit 16, whose output is added to the ignition angle from the control system, thereby using the sum as the ignition angle of the next cycle of an operation part 4.

Abstract: PURPOSE:To reproduce an information signal without fail even in a transmission line with a lot of noise by converting a demodulated signal to a digital signal, afterwards, cumulatively adding the digital signals during a period corresponding to a synchronizing signal and reproducing the information signal. CONSTITUTION:This digital communication system is composed of a first equipment with an information signal generating means 13 to output the information signal synchronously with a reference signal from a reference signal generating means 12, modulating means 17 to modulate this information signal and transmitting means 18 to transmit a modulated output, and a second equipment with a receiving means 20 to receive the signal from the transmitting means 18, demodulating means 25 to demodulate the received signal, analog/digital converting means 27 to convert the demodulated output to the digital signal, adding means 29 to cumulatively add the output signals during the period corresponding to the cycle of the reference signal, and means to reproduce the information signal based on the added output. Thus, since the signal received synchronously with the reference signal is demodulated, converted to the digital signal and cumulatively added, the information signal is exactly restored even in the case of including a lot of noise in the transmission line or the like.

Title: Drawing reader
Inventor: HONDA MASAKAZU
IPC: G06F17/50
Filed: 1985-07-04
Abstract: PURPOSE:To read a drawing by a simple processing by detecting the first segment longer than the previously determined length, separating it from the second segment other than it, and automatically discriminating a category discriminating symbol written in the vicinity of the first segment to decide the category of the drawing. CONSTITUTION:The output signal of a scanner 1 is once stored in an image memory 2. Then, the signal read from an image memory 2 is discriminated as a succeeding segment and one except for that by a succeeding segment detecting circuit 3. Thus, the signal of the image memory 2 is fed to a character discriminating circuit 5 through a gate circuit 4. At this time, a gate is applied to the signal of a graphic part already discriminated so as to prevent from passing, so that only the character signal is fed. Since in the image memory 2, the signals of the drawing 10 are accumulated from a left upper part in the sequence of smaller number of addresses, when the signals are read in the sequence of the addresses and more than the determined number of black signals is succeeded, they are recognized to be the segments of the graphic forms 11-16.

Title: Measuring method for wobbling track
Inventor: ENDOU SOUMEI
IPC: G11B7/26
Filed: 1988-06-17
Abstract: PURPOSE:To simplify a measuring job of the wobbling tracks by detecting the wobbling and traverse signals out of the laser light irradiates an optical disk and obtaining the normalized wobbling value. CONSTITUTION:An optical disk D to be tested is set on a player. Then the output level of the wobbling signal Iw obtained in a normal tracking state is compared with the output level of the tracking error signal IT outputted in a tracking-off state. Thus the normalized wobbling value NWS is detected for normalization of the wobbling value W. The value NWS is approximately proportional to the value W regardless of the form of a group groove and the influence of a reproduction optical system. Thus the value W can be evaluated by the value NMS. Furthermore the actual value W can be measured based on the value NWS. Thus it is possible to simplify the measuring job of the wobbling tracks and to facilitate the evaluation of the disk quality.
