Title: Welded joint with improved fatigue strength
Inventor: SUNAMOTO DAIZOU
IPC: B23K31/00
Filed: 1978-03-06
Abstract: PURPOSE: To increase fatigue strength by making a notch of suitable length in the end part of core material for making welded joint of welded construction in parallel with, or at a suitable angle with, the bead.  
     CONSTITUTION: In welding a plate 1, 400mm in length, with a core material 2, 200 mm inlength, a notch 4 (or either A or B form) 30 mm in length and 5 mm in breadth is made at the end part of the core material 2 in parallel with the bead. As the result, inflow of stress from the core material 2 to the plate 1 becomes smooth, so that the fatigue strength is increassed as much as 30W80 %, decreasing the dangerous points of the plate 1, and reducing the happening of serious accidents.

Title: Dc uninterruptive power feeder
Inventor: YAMAMOTO KATSUHIKO
IPC: H02J9/06
Filed: 1991-02-19
Abstract: PURPOSE:To supply the power from a storage battery without break even in the case where the AC power gets in power stoppage condition by magnetically coupling the two pairs of input ends and the two pairs of output ends of a DC-DC converter, and changing over the combinations of input terminals and output terminals. CONSTITUTION:A DC-DC converter 13 converts the power from an AC-DC converter 3 onto the voltage level that the load 5 requires, when AC power is supplied, and converts it into DC, and smooths it and supplies it to the load 5. When AC power is not supplied, it converts the power from the storage battery 2 onto the voltage level and converts it into DC and smoothes it, and then supplies it to the load 5. Hereby, even at emergency power stoppage or power stoppage, the load 5 can be supplied with power without instantaneous break as in the past.

Title: Production of information recording medium
Inventor: YABE MASAO
IPC: B41M5/26
Filed: 1987-02-04
Abstract: PURPOSE:To permit formation of a recording layer on a substrate by a coating method without dissolving the substrate by dissolving a dye into a solvent contg. a fluorinated ether to prepare a coating liquid, then coating the coating liquid on the substrate and drying the coating, thereby forming the recording layer. CONSTITUTION:The coating liquid is prepd. by dissolving the dye into the solvent contg. the fluorinated ether and thereafter, the coating liquid is coated on the substrate and the coating is dried, by which the recording layer is formed. More specifically, the fluorinated ether to be used as the solvent has high solubility with the dye such as cyanine dye and, therefore, the coating liquid for forming the recording layer can be easily prepd. Since this compd. is inert to the substrate consisting of a plastic material such as polycarbonate, the dissolution of the substrate in the coating stage does not arise. The information recording medium having high performance is thereby produced without generating the loss of grooves on the substrate surface and the degradation in the reflectivity of the recording layer.

Title: Electric cleaner
Inventor: MIYAZAKI YOSHIFUMI
IPC: H02P27/02
Filed: 1983-02-16
Abstract: PURPOSE:To enable to regulate a suction force automatically or preferably in response to the clogged state of a filter or the suction state of a suction port by providing manual suction force control means in an electric cleaner for automatically controlling the suction force. CONSTITUTION:The static pressure of a suction port 4 is transmitted through a pressure transmitting tube 9 to a semiconductor pressure sensor 10, which converts it to an electric signal. The signal is then amplified by an amplifier 36, and displayed on a display unit 38. On the other hand, the signal amplified by the amplifier 25 is fed back to a motor controller 27. Accordingly, the static pressure is large in the state that the filter is not clogged so that the feedback voltage becomes high, the ON period of a thyristor 39 becomes short to reduce the input, thereby reducing the static pressure. When the static pressure decreased, the feedback voltage becomes low, the input is, on the contrary, amplified, and held in balance at the prescribed point. Means for manually controlling the suction force via a variable resistor is provided, thereby preferably switching to automatic operation.

Title: Detecting circuit for duty cycle of signal
Inventor: HAYAKAWA MITSURU
IPC: H03K5/19
Filed: 1987-02-05
Abstract: PURPOSE:To highly accurately detect a duty cycle by setting up the output pulse width values of 1st and 2nd retriggerable monostable multi-vibrators(RTMM) as the upper and lower limit values of a period of a signal to be detected and determining the pulse width on the basis of a reference voltage. CONSTITUTION:When a signal Si to be detected is inputted to a limiter and a pulse P is applied to the RTMM1a, the pulse P is compared with a reference voltage VS1 by a comparator COMP1, an output pulse from the COMP1 is integrated by an integrator INTC1, an error between the integrated value Vint1 with a reference value Vref1 by an error amplifier EA1, and the amplified voltage is converted into current by a voltage/current converter VIC1 to control a lamp generating circuit REG1, trigger the RTMM1a at the leading edge of the pulse P and generate a pulse P1a with width shorter than a previously fixed ratio. An RTMM2a is also triggered at the leading edge of the pulse P1a by the similar constitution and a pulse P2a with the width longer than the period of the signal Si by a previously fixed ratio is generated. A decision pulse P0 with the prescribed pulse width is generated from the trailing edge of the pulse P2a by a PS. Even it the constant of the circuit is changed, the detecting accuracy is not deteriorated, and even when the frequency of the signal Si is changed, the duty cycle can be detected without generating any trouble.

Then, one or multiple layers of paddings 13 are applied from the top surface of the grooves 12 according to said depth. Thereafter, the inside surfaces of the parts near the corners are cut in consideration for the thickness of the padding on the inside surface of the metal 11 in the part except near the corner part. Finally, the padding of only one layer is executed on the required parts of the top surface of the metal 11 and down to the prescribed depth of the inside surface, after which these are finished by cutting, whereby the die for drawing of square cylinders is perfected. Here, 15 denotes the padded metal of the inside surface. Inexpensive, strong and tough steel materials such as SS41 are suited for the base metal, and copper-Al alloys, etc. of superior abrasion resistance and seizure resistance are suited for the padding metal.
