IPC: H05K3/34
Filed: 1991-11-11
Abstract: PURPOSE:To improve the productivity of a printed wiring board in the case where leads are inserted in the printed wiring board through both surfaces of the board and to lessen an irregularity in the quality of the board by a method wherein the leads of a second insertion component are pressed in through holes, in which solder is previously fed through the other surface of the printed wiring board. CONSTITUTION:Leads 22 and 22 of a first insertion component 20 are inserted in a printed wiring board 10 through the side of the surface 18 on one side of the surfaces of the printed wiring board 10 and are dipped in a molten solder tank 26. Then, the board 10 is vertically inverted and the other surface 24 of the board 10 is faced upward. Pin holes 62 for positioning use are engaged with pins 56 and a second insertion component 28 is inserted in a component hole 64 in this positioning plate 58. At this time, leads 30 of the component 28 are abutted on a solder solidified in through holes 14 and 14. In this state, the whole body is heated by an infrared heater 66. The solder in through holes 12 and 12 and the through holes 14 and 14 is molten by this heating and at this time, the leads 30 intrude into the holes 14 and 14 by the weight of the component 28.

Title: Production of reflecting mirror of multilayered film
Inventor: MORISHIGE MAKOTO
IPC: F21V7/22
Filed: 1987-12-18
Abstract: PURPOSE:To improve heat resistance and moisture resistance by alternately laminating thin films having oxygen defects of silicon oxide and titanium oxide on a reflecting base plate, then subjecting the same to a heating treatment in the atm. or oxygen atmosphere. CONSTITUTION:Formation of a TiO2 film is executed by forming a Ti2O3 film by using a Ti2O3 material which is easily depositable by evaporation, then subjecting the film to the heating treatment in the atm. or oxygen atmosphere to oxidize the film, thereby obtaining the TiO2 film. Formation of SiO2 is similarly executed by forming an SiO film by using an SiO material, then subjecting the film to the heating treatment in the atm. or oxygen atmosphere to obtain the SiO2 film. Namely, the thin films having the oxygen defects of the silicon oxide and the titanium oxide are alternately laminated on the reflecting substrate 1 in the gaseous atmosphere having 10<-1>-10<-3> Pascal (10<-3>-10<-5>Torr) pressure and are then subjected to the heating treatment in the atm. or oxygen atmosphere. The heat resistance and moisture resistance are thereby improved.

A weir 50 disturbs direct communication of the lower part of the heat pipe steam condenser steam duct 30 with the internal part of the rise pipe 60. Steam condensate is moved through a drain pipe 70 located in each steam condenser duct 30 to a distribution multibranch pipe (a distribution main pipe) 80 located between a main steam duct 40 and an inlet to the interior of the rise pipe 60 of the heat pipe steam condenser steam duct 30. Condensed steam is injected through the spray pipe of the distribution multibranch pipe 80 to a position above an arbitrary condenser shelf plate 120 above the main steam duct 40. A drain pipe boot 20 is placed at the lower part of the main steam duct 40.

Title: Method for detecting minute defect of butt welded joint
Inventor: KAMITSUMA TSUYOSHI
IPC: G01N29/04
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To realize a method for accurately detecting minute defects even with a poor S/N ratio and many noise echoes by detecting the minute defects from an analyzed value of a specific frequency band of a power spectrum obtained through an FFT operation to a gate part of ultrasonic wave flaw detection waveform data. SOLUTION: A butt welded joint of a pipe of a small diameter to be inspected is subjected to ultrasonic flaw detection by a scanner having a unit of a transmission skew probe and a reception skew probe in pairs. A gate part in the obtained ultrasonic flaw detection waveform data is subjected to FFT(fast Fourier transform) operation, thereby obtaining a power spectrum. Even when an S/N ratio is poor and many noise echoes are included, the power spectrum is changed through a comparison with a part without a defect if the data includes information of defects. A range where a specific frequency band of the power spectrum changes most is analyzed. The presence/absence of minute defects is judged by a size of the analyzed value. Minute defects of even the butt welded joint of a thickness smaller than 3.5 mm can be accurately detected in this manner.

Title: Torque limiting clutch
Inventor: KURAUSU KEMUPUFU
IPC: F16D7/04
Filed: 1992-11-09
Abstract: PURPOSE: To sufficiently prevent the tilting moment which acts on driving members during torque transmission. CONSTITUTION: A torque limiting clutch 5 has a plurality of slide-like driving members 19 circumferentially and movably distributed in a clutch hub 10. The unit is rotatably accommodated in a clutch sleeve 7. The driving members 19, with their torque transmitting faces 25 at their heads, are pushed by a spring assembly 29 and switching cams 32 into correspondingly designed recesses 22 of the clutch sleeve 7. A pressure springs 38, 39 and the switching faces 30, 31 of the driving members 19 as well as the torque transmitting face 25 are arranged so as to extend in the same direction to the pressure csrings 38, 39. Thus, the springs 38, 39, during the transmission of torque in the arrowed direction N by the clutch sleeve 7, subject the driving members 19 to a moment which acts against the tilting moment resulting from the transmission of torque.  This results in an improved wear and switching behavior.

Further, a conveying member 8 conveys the slide rail 7 almost perpendicularly to the lengthwise direction of the hanging bar 1. Besides, since the mobile object 4 is conveyed while being abutted, an abutting member 14 makes the mobile object 4 slide in the lengthwise direction of the hanging bar 1.  Further, terminal part holding members 15 and 17 move the terminal part of the hanging bar 1 on the side of a guide member 14 in the almost same direction as the moving direction of the slide rail 7 while holding its terminal part.

Title: Gas measuring device
Inventor: MATSUNO GEN
IPC: G01N5/02
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To improve the sensitivity of a smell sensor and prevent the malfunction thereof due to the condensation or the like of measured gases by providing a dehumidifier at the pre-stage of a gas cooler for cooling the measured gases and the smell sensor. SOLUTION: A pump 2 draws measured gases from an intake port 1 and feeds the gases to a gas cooler 4 via a dehumidifier 3. The gas cooler 4 is formed, for example, out of Peltier elements or the like, and cools the measured gases down to a zero degree. On the other hand, a sensor cell 5 is also cooled down to a zero degree with a sensor cell cooler 7 formed out of Peltier elements or the like, and the output gases of the gas cooler 4 are fed to the cell 5. Also, the measured gases are sequentially discharged from an exhaust port 9. Furthermore, a smell substance contained in the measured gases adsorbs to the gas adsorption membrane of a smell sensor 6 in the sensor cell 5, and the resonance frequency of the smell sensor 6 is thereby changed. A measuring circuit 8 detects and outputs the resonance frequency change externally as an output signal 100.  In this case, the adsorption amount of the smell substance increases, when the temperature of the smell sensor 6 is lowered.

IPC: E04B1/00
Filed: 1993-12-21
Abstract: PURPOSE:To form a floor which is safe and has good outward appearance by integrally providing a water stop material made by water absorptive resin in the inner wall surface of an engaging recessed part where the peripheral edge part of a floor panel is engaged to connect floor panels to each other without a recess in a joint part. CONSTITUTION:Both side surfaces of a joint 1a are formed as engaging recessed parts 2 to make a substantially I-shaped section. The end edge parts of floor panels 3 are engaged with engaging recessed parts 2 of the joint 1a from both sides so that the floor panels 3 are connected to each other through the joint 1a. At that time, water stop materials 4 are integrated with inner wall surfaces 21, 22 opposite to upper and lower surfaces 31,32 of the floor panels 3. The end edge of the surface side of the joint 1a is notched to be tapered, so that when the water stop material 4 is moistened by water, it is swollen to enable complete sealing. Further, the floor panel 3 is made freely move and the thermal expansion and contraction of the floor panel 3 is absorbed by elasticity of the water stop material 4. Thus, small of a joint part can be prevented. Accordingly, a floor which is safe and has good outward appearance can be formed.
