Abstract: PURPOSE:To obtain a polyethylene coated pipe which is excellent in wheathering and handling resistance by a method wherein an outer surface of a steel pipe is coated with a polyethylene resin layer consisting of a specific white polyethylene composition via an adhesive layer. CONSTITUTION:An outer surface of a steel pipe is coated, via an adhesive layer, with a polyethylene resin layer of at least 0.5mm film thickness consisting of a white polyethylene composition wherein at least 0.5 pts.wt. of color pigment in which white pigment is at least 75%wt.% is added to 100 pts.wt. of polyethylene.

Title: Weld joint
Inventor: MOCHIZUKI MASATO
IPC: B23K31/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To mitigate stress concentration in the root and the toe part of a weld joint and to reduce residual stress by welding these parts further using a welding rod by a material causing martensite transformation and thereby smoothly forming the shape. SOLUTION: The flange 3 and the web 4 of a Tee joint are joined by electron beam welding 1. Upon completion of the electron beam welding 1, the weld zone of the Tee joint is repeatedly given cladding by welding using a welding rod by a material causing martensite transformation in the manner that stress concentration is prevented, so that the root and the toe part of the Tee joint are welded 2 in a smoothly curved shape. After completion of the welding 2, for the purpose of obtaining a joint shape free of stress concentration, it is desirable that the root and the toe part of the Tee joint are smoothly machined preliminarily by grinding and that electron beam welding is then performed on these parts. As a result, fatigue strength is improved in the weld zone of the joint, enabling reliability to be enhanced for the joint.

Title: Soldering method for suppressing fillet lifting
Inventor: TAKAO HISAFUMI
IPC: H05K3/34
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To suppress fillet lifting which stripps solder from a land by heating the lead of a part directly or indirectly when a part having a lead is mounted on a printed wiring board thereby retarding solidification of solder in the vicinity of the lead. SOLUTION: A part having a lead is mounted by soldering to the through hole 12 of a printed wiring board 10 using a connector 20. The solder 30 is composed of an Sn-Bi alloy having wt.% of 93:3 and has a melting point in the range of 219-230 deg.C. Soldering is carried out by supplying hot air to the lead 22 to form a molten solder fillet at a solder joint and further supplying hot air for about 10 sec until the solder 30 is solidified thus retarding solidification thereof. Consequently, fillet lifting which stripps solder from a land canbe suppressed.

Title: Down edge detecting circuit
Inventor: WADA YOSHIFUSA
IPC: H03K19/195
Filed: 1983-07-20
Abstract: PURPOSE:To detect the down edge of a current flowed to a primary winding of a transformer by changing the state of a resistance coupled OR circuit consisting of a resistance and a Josephson device when this current is reduced to zero. CONSTITUTION:If the input signal current flowed to the primary winding of a transformer 101 is increased from zero in the direction of an arrow 121, a Josephson device 103 is switched to the resistance state when a branch current, which is flowed to the Josephson device 103, of the secondary current induced in the secondary winding in the direction of an arrow 122 reaches a threshold, and the current of the secondary winding of the transformer 101 is attenuated. If the input signal current is reduced to zero from a regulated value or a maximum value, the Josephson device 103 is switched to the resistance zero state and is held in this state to switch a resistance coupled OR circuit 102. A resistance 105 connected in parallel to the Josephson device 103 functions as a damping resistance when the Josephson device 103 is switched to the resistance state to attenuate the current of the secondary winding, and this resistance 105 eliminates the oscillation in case of current attenuation and shortens the attenuation time and make a high-speed circuit operation possible.

Filed: 1990-05-23
Abstract: PURPOSE:To carry out analysis without receiving the effect of background radioactivity or the oxide compound in off gas and generating the deterioration of an electrode by using electrodeless discharge plasma due to high frequency discharge in optogalvano-analysis. CONSTITUTION:Off gas containing krypton being a substance to be measured is introduced into a discharge cell 2 by a vacuum pump 1. The high frequency power generated from a high frequency power supply 5 is transmitted to a discharge cell and the carrier gas introduced into the discharge cell 2 is ionized to generate an electron. This electron receives high frequency energy to be accelerated to excite krypton. A wavelength variable laser generating part 8 forms laser beam having the wavelength resonated with krypton and, when the discharge cell 2 is irradiated with the laser beam by an optical chopper 9, krypton in the discharge cell 2 is further excited to generate a change in the impedance within the discharge cell 2. This change is taken out by a coil 10 to be sent out to a lock-in amplifier 12 and a phase is detected to know the conc. of krypton on the display of an output meter 13.

Filed: 1980-09-24
Abstract: PURPOSE: To maintain the current flow rate of a chopper bofore and after the variation in the chopping frequency of the chopper constantly by varying the gradient of a triangular wave inputted to a phase shifter at the time of switching the frequency.  
     CONSTITUTION: A comparison amplifier 1 outputs a deviation Vpp between a main motor current instruction value Iap and a main motor current feedback value Iaf. A triangular wave generator 2 outputs a triangular wave of the period proportional to the output of an oscillator 3. A phase shifter 4 calculates the current flow rate of the chopper with the outputs from the amplifier 1 and the generator 2 as inputs. When the chopping frequency is varied by 1/2f0Wf0, the gradient of the output of the triangular wave generator is increased twice simultaneously upon variation of the chopping frequency by the frequency variation instruction fv of a frequency variation instruction unit 5. In this manner the current flow rate before and after the variation of the chopping frequency can be maintained constantly, thereby eliminating the abrupt variation of the torque.
