Title: Welding method of fillet weld joint
Inventor: YAMADA ASHIAKI
IPC: B23K9/23
Filed: 1979-05-16
Abstract: PURPOSE: To enable the obtaining of the strapped welded joint or lap welded joint which does not cause fatigue fracture by making the throat depth and leg length size of the fillet weld zone to the specified times or more of the thickness of the materials to be welded.  
     CONSTITUTION: In the case when this method is executed to strapped welded joint, for example, in the Ti-clad vessel composed of Ti strap metal 1, clad metal 2 of Ti, base metal 3 of carbon steel, strap deposited metal 4 of Ti and base metal deposited metal 5 of carbon steel, the strap metal 1 and metal 2 are fillet-welded. In this case, the fillet welding is accomplished by reinforcement padding 10 at both ends on the strap metal 1 and the throat depth size (i) and filler leg length (k) are made twice or more the strap plate thickness size (h) so that the rectangular section to the advancing direction of welding becomes the shape shown by the metal 4. As a result of this, the fillet leg length and throat depth may be increased, the stress concentration of the fillet root part released, notch effect decreased and the fatigue strength of the strap welded joint and lap welded joint improved.

IPC: H01M6/02
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To smoothly obtain a wound body with high accuracy without loosening it by imparting roll-in frictional resistance by always bringing a resistance imparting means into contact with a peripheral surface of this wound body in the middle when the wound body transfers to a tape sticking mechanism. SOLUTION: After separators 14a and 14b of a wound body 16 are cut through a cutting mechanism, the body 16 rotates in the arrow B direction, and sticking work of a tape 19 is performed. In the middle of this, a roller 46 to constitute a resistance imparting means 44 of a roll-in mechanism 30 is brought into contact with a peripheral surface of the wound body 16. A plate body 48 slidingly contacts with this roller 46, and rotational resistance is imparted to the roller 46. Therefore, the roller 46 can always impart roll-in frictional resistance to the peripheral surface of the body 16. Therefore, when negative electrode lead 18 passes through between the roller 46 and the body 16, even if the negative electrode lead 18 protrudes outside the body 16, the roller 46 neither springs up and rotating speed of the roller 46 nor increases.

Title: Focal point error detector
Inventor: MAEDA TAKANORI
IPC: G11B7/133
Filed: 1987-03-13
Abstract: PURPOSE:To set only one zero cross point and to perform stable focus servo, by forming the central part of an optical detector divided into three parts larger than both side parts substantially. CONSTITUTION:The optical detector 1 is divided into three parts A-C substantially by a parting line, and the outputs of the parts A and C are added by an adder circuit 3, and a differential amplifier circuit 2 as a generation circuit generates a focal point error signal from a difference between the output of the part B and that of the circuit 3. The constitution of the detector 1 is formed so that the length of the part B in a direction of the parting line can be set larger than those of the parts A and C substantially. Therefore, the output of the circuit 2 in which the sum of the outputs of the parts A and C is subtracted from the output of the part B goes to a zero level at a focused state. Also, when a focal point is deviated from the focused state to a side on one side, the level of the output of the circuit 2 keeps a negative level, and when it is deviated to the side on the other side, it keeps the positive level, then, the zero cross point is set only at a focused position. In such a way, it is possible to obtain the stable focus servo.

Title: Method for controlling speed of pulse motor
Inventor: KOIDE HIROSHI
IPC: H02P8/14
Filed: 1979-05-16
Abstract: PURPOSE:To perform stable speed control, by exciting an exciting phase at the stable point between the position at which a motor can be stopped one step further than the present position and at the position at which the motor can be stopped two steps further if the speed is slower than the reference speed, and by exciting the exciting phase which generates a thrust in the reverse direction if the speed is faster. CONSTITUTION:A position signal is generated by a position detector PD and a position-signal generator PG and is input to a pulse-motor controller C together with the signals from a speed-signal generator VG and a speed-zero detector ZD. A reference- speed designating voltage from the controller C is compared with a speed signal VE in a comparator COM, and supplied to a driver circuit DU. If the speed is slower than the reference speed, the exciting phase is excited at the stable point between the position at which a motor can be stopped one step further than the present position and at the position at which the motor can be stopped two steps further. If the speed is faster, the exciting phase which can generate a thrust in the reverse direction is excited, and the motor is driven. Since the feedback is always applied, the stable controlling can be accomplished.

Abstract: PURPOSE:To achieve the performance of a CPU to the maximum and to obtain a printed image whose quality is excellent by using a crystal oscillator having frequency which is 1/16 of clock for transferring the image for the transfer of the image and the clock for the CPU. CONSTITUTION:The output of the crystal oscillator 1 is frequency-divided to be 1/2 through an FF 2 and taken as the clock for the CPU 3. The head pulse of an input signal 4 is detected by FFs 5 and 6 and a NAND gate 7, and loaded to a four-bit synchronizing counter. Since the logic of terminals D0-D3 is fixed to be zero, a counted value is zero at the rise of the clock and 1/16 of clock frequency is obtained from a terminal Q3 after load input is invalid. At the rise of the clock, one dot of image information is transmitted to a printer engine. Since the load time of the four-bit synchronizing counter 8 is 1/16 of clock for transferring the image information, the deviation in a horizontal direction in the case of printing plural lines is restrained to be 1/16 for one dot of image data. Then, the performance of the CPU is achieved to the maximum and the high-quality printed image is obtained.
