Abstract: PURPOSE:To obtain a traveling-wave tube with high output and high efficiency having the suppressed backward-traveling wave oscillation by constituting the speed tapering part of a lagging wave circuit with the plurally stepped speed tapering having different change rates of a circuit period. CONSTITUTION:The circuit period of a helix type lagging wave circuit is selected to be the circuit period P0 synchronizing with an electron beam in the lagging wave circuit 7 on the input side, while constituting the lagging wave circuit 9 on the output side with the three parts comprising a circuit period part 10 larger than the circuit period of the lagging wave circuit on the input side and a small circuit period part 14 as well as with a speed tapering part 15 changing from the large circuit period to the small circuit period. Further, the speed tapering part 15 consists of two kinds of speed tapering 11 and 13 having the different change rares of the circuit period. Thereby, the efficiency is improved while also being able to simultaneously suppress the backward-traveling oscillation.

Title: Torque limiter of conveying motor in conveying apparatus
Inventor: MIYAJI SUMIYUKI
IPC: B60L15/40
Filed: 1985-04-10
Abstract: PURPOSE:To suppress an impact force at stopping time by switching the set level of a torque limiter to a low level when a rotating speed signal substantially comes to constant value and a low speed feed designation signal is input. CONSTITUTION:An instruction unit 22 outputs a speed command value V on the basis of an operation designation signal from a sequence instruction unit 20 and a speed set value from a speed setter 21. A differential amplifier 23 applies a control signal in response to a deviation between a speed command value V and a speed signal to a power amplifier 2. A torque limiter 28 applies a signal voltage -V' of the prescribed value indicated in advance when a current I flowed to a conveying motor 10 exceeds the prescribed level to limit a current I. A torque limiter switch 40 outputs a switching signal S5 when a speed signal comes to substantially constant value and a low speed feed designation signal from the unit 20 is output, thereby reducing the limit value of the limiter 28.

IPC: H01L21/822
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To ensure stabilized operation of a scan circuit regardless of skew of scan lock by constituting the scan circuit of scan cells also outputting a scan lock signal. SOLUTION: A scan lock 201 is connected with a final stage scan cell 212 and a scan lock output 208 therefrom is employed as the scan lock for a second scan cell 211. A scan lock 203 outputted from the scan cell 211 is connected with a first scan cell 210 to end a scan lock path. Distortion of the scan clock clock waveform due to the effect of wiring resistance or wiring content can be suppressed by incorporating scan clock buffers in several scan cells of a scan circuit thus constituted and the scan cell, area can be minimized while suppressing the charge/discharge current being applied to one scan clock by dividing the charge/discharge current for several butters.

Abstract: PURPOSE:To automatically change the communication speed into an optimum communication speed in response to a data error rate even in the communication state. CONSTITUTION:Upon the detection of an error in a frame data received through a line connection line 12, an error detection circuit 17 reports it to a reception frame error detection frequency measurement section 14 and makes a request of transmission of an error check notice frame leading to an opposite station to a central controller (not shown). On the other hand, when an error detection notice frame as to the frame data sent to the opposite station is sent from the opposite station, the frame is transferred to a transmission frame error detection frequency measurement section 15. The count of a counter 19 is counted up by every error detection report from the reception frame error detection frequency measurement section 14 and the transmission frame error detection frequency measurement section 15 and the result is reported to a speed command circuit 18 for each prescribed time. The speed command circuit l8, based on the report, instructs re-setting of a proper data transmission speed to a communication controller main body 11.

Title: Multiple stages cluster rolling mill
Inventor: YOSHINO KAZUO
IPC: B21B13/14
Filed: 1981-05-20
Abstract: PURPOSE:To improve shape controlling ability with the bending effect of intermediate rolls and the projecting shape effect of split reinforcing rolls in a multiple stages cluster rolling mill by moving a pair of upper, lower work rools in mutually opposite directions in the axial direction of the rolls. CONSTITUTION:The effective ends of upper, lower work rolls 2 are moved and set to at the positions apart by certain distances from both ends accaording to a rolling material 1. While the above-described distances are changed depending upon the shape of the material 1 after the rolling, roll bending devices 10 mounted between intermediate roll metal chocks 7 and housing 9 are actuated. Since the rolls 2 are small in diameter, the parts in contact with the material 1 bend along the rolls 3, and as the positions of the reaction of rolling acting upon the rolls 2 from the rolls 3 go nearer the end parts of the material 1, the bending moment by the contact load received from the rolls 3 decreases and the bending deformation of the work rolls in the end plates of the plate is reduced. At the same time, the deformation of the work rolls near the end parts of the plate by the rolling load is corrected by crown, whereby the rolled products of good shapes are obtained.

Title: Water purifier
Inventor: KAWAI YU
IPC: B01D35/027
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To secure a water passage, even if a circulation passage is blocked by the adhesion of aluminium hydroxide between electrodes in a flocculation means, to continue the filtration operation, and to prevent the circulation passage from being damaged even if a clearance between the electrodes is blocked by internal stress caused by the generation of aluminium hydroxide. SOLUTION: The installation of a clearance 13e between a cathode 13c and a filtration tank case 12a having the cathode built-in secures a water passage during filtration, even if a clearance 13b between an anode 13a and the cathode 13c is blocked, which prevents water to be filtered from not flowing for filtration. Moreover, if the cathode 13c is pushed and expanded toward the tank case 12a when the clearance 13b is blocked, a clearance 13e between the case 12a and the cathode 13c works as a buffer body to prevent the tank case 12a from being damaged. As a result, the water leak, which is caused by the damage to a filtration means 12 by internal stress due to the generation of aluminium hydroxide after blocking the clearance 13b, can be prevented.

Title: Printing sheet guiding device for printer
Inventor: MIMASU KAZUO
IPC: B41J13/10
Filed: 1989-03-27
Abstract: PURPOSE:To eliminate irregular density of a print by forming a structure in which a gap between a guide member and a platen roller is narrowed, and providing a spring member for energizing a pressing roller and a shaft toward the central direction of the platen roller. CONSTITUTION:A printing sheet 22 fed in a gap to a guide face 6 wound on the outer surface of a platen roller 2 is accurately guided to guide faces 6, 6' since the gap is narrow to eliminate the disturbance of the rotation of the roller 2 due to the slack of the sheet. Since pressing rollers 8, 8' are slid out of through holes 7, 7' against a spring when the end of the sheet 22 is held by the rollers 8, 8', even if the sheet is thick and hard, the rotation of the roller 2 is not disturbed. Since the rollers 8, 8' hold the sheet from a direction perpendicular to the contact angle of the end of the sheet 2, the abrupt increase in the rotating load of the roller 2 is alleviated. Accordingly, even if the end of the sheet 22 to be conveyed is sequentially passed through the rollers 8, 8' during printing of a thermal head 15, the rotation of the roller 2 is not disturbed, but its rotating speed is made uniform to eliminate the irregular density of the print.
