Title: Manufacturing apparatus for semiconductor
Inventor: KOJIMA YASUTOMO
IPC: H01J37/317
Filed: 1980-04-18
Abstract: PURPOSE:To remove residing charges and improve the accuracy of impurity implantation by grounding a substrate-mounting table and an ampere-hour meter before or after bombarding a substrate with ions. CONSTITUTION:A ground contact plate 22 is attached to an inner wall 21 of the target chamber in an ion implanter, and a ground contact rod 23 to the back surface of a substrate mounting table 6. When a substrate P has been fed onto the table 6 and held by means of supporting pins 8, the table 6 rises to a specified angle to form a Faraday cup 9 and is bombarded with an ion beam 10, so that a current flows through an ampere-hour meter 13. After the completion of the bombardment  of ions, the table 6 falls, and the substrate P is delivered in the direction of an arrow 14. At this time, the contact rod 23 contacts with the contact plate 22, causing the table 6 and the ampere-hour meter 13 to be short-circuited with the ground 24, so that the charges residing since the implantation can be forcibly removed. Thereby, the accumulation of the residing charges can be prevented, and the accuracy of ion implantation can be improved.

IPC: B23K9/12
Filed: 1980-04-18
Abstract: PURPOSE: To place a welding torch in the correct position of the weld line by detecting the peak value of the arc current generated at both ends of weaving from the time differentiated value of the arc current and controlling the position by the deviation of the detected peak value.  
     CONSTITUTION: A welding torch 3 is on the base materials 1, 2 to be welded, moves in the welding direction by being supported with a torch traveling and supporting mechanism 4 and is moved in vertical and horizontal directions by vertical and horizontal direction moving mechanisms 5, 6. Also, a weaving mechanism 7 causes the tip to weave in the A, B ranges. The weaving positions are detected with a weaving position detector 8. Here, welding is started by applying current from a power source 9 to the welding torch 3, and when the torch 3 deviates to, for example, the base material 2 side, the peak value detected with an arc current detector 10 becomes larger at the weaving end A and becomes smaller on the opposite. The touch 3 is moved by the distance corresponding to this difference, whereby it is brought to the correct position.

Abstract: PURPOSE:To obtain a device capable of judging the certainty of an unknown word section by identifying the unknown word section through retrieval of a partial pattern table stored in a storage means by an unknown word processing means in the case that the unknown word described by KANA (Japanese syllabary) is contained in an inputted character string.

Abstract: PURPOSE:To adjust the phase of a chrominance subcarrier without deteriorating the frequency characteristic and the transient characteristic by using a phase shift circuit so as to generate three kinds of carriers and selecting a different carrier given to a balanced modulator for each of even and odd number lines depending on a burst signal period and other signal periods. CONSTITUTION:A carrier generating means comprising a phase comparator 8, a reference oscillator 9, a low pass filter 10, a VCO 11, a PS circuit 12, a sub balanced modulator 13 and a band pass filter(BPf) 14 generates a conversion carrier, and a phase shift circuit 30 is used to generate 2nd and 3rd carriers whose phase is lagged or led from the conversion carrier by a prescribed phase angle. The signal to be given to a balanced modulator 3 is selected by using a switching signal generating circuit 35 and a selection means 34 so that a 1st carrier is given to the balanced modulator 3 for a 1st period including a burst signal portion and a 2nd or 3rd carrier is given thereto for each of even and odd number lines for the other period alternately thereby obtaining a chrominance carrier signal whose hue is changed. Thus, the hue of a chrominance subcarrier is adjusted without deteriorating the frequency characteristic and the transient characteristic.

Title: Dehydration apparatus and washing apparatus for continuous knit fabric
Inventor: HIKOSAKA HIROSHI
IPC: D06B5/08
Filed: 1992-01-28
Abstract: PURPOSE:To restrict the elongation of a continuous knit fabric within an allowable limit in the traction of the fabric with a friction roller in a state covering a group of nonparallel slits having lateral symmetry and bored on one side of a horizontal suction pipe. CONSTITUTION:The objective dehydration apparatus for a continuous knit fabric is provided with a friction roller 8 and a screw roller 10 before and after the knit fabric 7 slidably contacting with nonparallel slit groups 4 of a suction pipe 2. The width of the knit fabric is expanded to nearly the maximum width by the screw roller 10. The distance between both rollers is shortened as far as possible within a range not to hinder the flow of the sucked air flow to the nonparallel slit groups 4. The above dehydration apparatuses each having a means for supplying water to the introduced knit fabric are placed at both sides of the suction pipe 2 of the objective washing apparatus for the continuous knit fabric. The suction pipe 2 has two nonparallel slit groups 4, 5 having opposite directions to each other. The contacting angle of the knit fabric on the screw roller 13 is controlled by passing the fabric on a weight-operated dancer roller 16 placed between both dehydration apparatuses. The width of the knit fabric can be expanded to nearly the maximum width by this method without excessively increasing the tension of the fabric in longitudinal direction.

Title: Picture extracting system
Inventor: MAEZAWA YASUNORI
IPC: G06T9/00
Filed: 1982-03-30
Abstract: PURPOSE:To extract automatically a desired picture region in an original with no intervention of an operator, by counting the quantity of the coding data corresponding to the pictures of each fixed region of the original and then extracting the picture region to be transmitted and received in response to the count value of said coding data quantity. CONSTITUTION:The line coding data quantity is increased at a region A where an inserted figure 2 is drawn, and a waveform (a) is sliced with a threshold level (k) to obtain an effective information line region A. A detecting part 4 detects the synchronizing signal SYN out of a signal train and delivers it to counters 5 and 6. The counter 5 adds +1 to its count value with an SYN detecting signal supplied from the part 4. While the counter 6 counts the number of bits of an input signal train, and this output value is identical with an output corresponding to the bit number for each 1-line coding data MD, i.e., the waveform (a). A comparator 7 slices the bit number output with the level (k) and therefore informs the detection of effective information to the counter 5. In such a way, the counter 5 delivers both head and final numbers of a line of the effective information on the basis of its own count value.

Title: Facsimile test system
Inventor: IIZUKA YOSHIO
IPC: H04N1/32
Filed: 1982-03-30
Abstract: PURPOSE:To perform the test of both reading and recording systems at one time without using any hardware, by storing a fixed pattern while a fluorescent lamp of the reading system is kept glowing with use of a function of printing of an originator. CONSTITUTION:When both a fluorescent lamp and the sensor output are normal, a normal state detecting signal of the reading system is delivered to an MPU1 from a light volume checking circuit 8. Thus the MPU1 generates an address to deliver a pattern of an F region shown in the diagram. In this case, only ''0123-P45'' of the region F is stored with the output given from an MPX4, and then only ''0101'' is delivered from the MPU1. Then the white part of the region F is recorded. The MPU1 delivers continuously the addresses and delivers regions A-E. In such a way, the tests are carried out to the printing of originator of the region F as well as to fixed patterns of regions A-E. In case the reading system has no normal working with insufficient luminosity of the fluorescent lamp or the abnormal output of the sensor, an abnormal state detecting signal is delivered to the MPU1 from the circuit 8. Then the MPU1 delivers continuously the address ''1101'' and the entire region F has a black output. Therefore it is judged that the function of the reading system is normal if the region F is printed, and then abnormal if the region F has a full black output. Furthermore, the abnormal part of the recorded area can be detected from the recording state of the fixed pattern as well as the printing state.
