Abstract: PROBLEM TO BE SOLVED: To make a table be easily changed between a used condition and an unused condition. SOLUTION: A support leg 3 is equipped foldably under a top plate 1 by a support pin 5. A plate spring 9 is equipped under the top plate 1. The leaf spring 9 is formed so as to be in contact with the upper end face 3a of the support leg when the support leg is unfolded to stand up the leg and with a side face 3b of the support leg when the support leg is folded to lay down the leg. Under the top plate 1 in the opposite side of the laying direction of the leg 3, a guide metal 11 equipped with an elevatable lock ball 10 is disposed. In a using condition the support leg 3 is unfolded to stand up, the lock ball 10 is put in between the guide metal 11 and a side face of the support leg 3 at the upper position of the support pin 5 to lock the standing condition of the support leg 3.  When the table is turned over so as to make the top plate down side, the lock ball 10 is disengaged from the support part so as to release the lock. The guide metal 11 is equipped to make the top plate 1 side of the metal in an inclined condition to the outside opposite to the support leg 3.

Title: Sealed secondary battery
Inventor: TAKESHIMA GENJI
IPC: H01M10/52
Filed: 1982-11-24
Abstract: PURPOSE:To decrease the increase in internal pressure during charging of a sealed secondary battery containing aqueous electrolyte by either applying carbonaceous powder to or bringing carbonaceous sheets into contact with parts of negative electrodes used to constitute the battery. CONSTITUTION:Sintered positive nickel plates 1 and sintered negative cadmium plates 2 are alternately placed with separators 4 made of a nonwoven nylon fabric interposed. Next, sheets 3 formed by the use of mixture prepared by combining coconutshell active carbon powder with polytetrafluoroethylene used as a binding agent, are brought into contact with the back surfaces of negative plates 2 located at the ends before the thus assembled body is installed in a container 6. After that, electrolyte consisting of 35% aqueous caustic-potash solution is poured thereby constituting a sealed nickel-cadmium secondary battery. As a result, oxygen gas generated from the positive electrodes 1 during charging can be electrochemically reduced by using the sheets 3 as a catalyst. Consequently, easy sealing of the battery is secured by decreasing the increase in its internal pressure.

Title: Hot dip galvanizing bath composition
Inventor: FUNAHASHI TSUNEO
IPC: C23C2/06
Filed: 1989-08-11
Abstract: PURPOSE:To obtain a hot dip galvanizing bath compsn. not causing ungalvanizing even by a single galvanizing work by incorporating a specified amt. of In into a hot dip galvanizing bath contg. a specified amt. of Al added so as to ensure corrosion resistance. CONSTITUTION:This hot dip galvanizing bath compsn. consists of 3-10wt.% Al, 0.1-4wt.% In and the balance Zn. In improves the adhesion of a Zn layer to a body to be treated, does not cause ungalvanizing and forms a uniform Zn layer but <0.1wt.% In is not well effective in improving the adhesion. Even when the amt. of In exceeds 4wt.%, the above-mentioned effects are not necessarily enhanced and galvanizing cost is increased because in is expensive.

Abstract: PURPOSE:To automatically correct errors due to zero-shift temperature characteristics, by shutting off the pressure supply air to present a state of differential pressure 0, detecting and storing the output voltage value, and subtracting the value from the output voltage value in the measurement carried out later. CONSTITUTION:When a solenoid valve 16 is closed, both pressures inside differential pressure chambers 1, 2 become equal to the atmospheric pressure. In  other words, the differential pressure chambers 1, 2 have a pressure difference  DELTAp=0 therebetween, and the output voltage Vout of a differential pressure converter 13 at this time is b'. A controller 18 receives and stores the value of b'. The solenoid valve 16 is opened, and the positive and negative signs are inverted  to calculate -b', which is applied to an adder 17 through a feedback line 21.  The adder 17 adds -b' to the value of the output signal from the differential  pressure converter 13 and delivers the result as a corrected output voltage.  Since -b' is added to the output voltage characteristic curve 15 after change, the curve 15 downwardly moves parallelly by the dimension of b'.

Filed: 1982-11-24
Abstract: PURPOSE:To obtain the highly sensitive and simple measuring method for impurity levels by a method wherein a monochromatic light less than the energy corresponding to a forbidden bandwidth is radiated to the positive electrode in an electrolytic etching cell using a semi-insulating semiconductor crystal and the variation of photoelectric current is detected. CONSTITUTION:A semi-insulating GaAs crystal 4, which is used as a positive electrode provided with a lead wire, and a metal negative electrode 5 have been soaked in the electrolyte in an electrolytic etching cell 3 and a DC voltage from a power source 8 has been applied between the positive and negative electrodes. Under this condition, when a monochromatic light is radiated to the surface of the semi-insulating GaAs crystal 4 from a spectroscope 2 and there is a deep impurity level at a position corresponding to a certain wavelength among those of the incident lights, an electron or a hole captured at the level is excited at the conduction band or the value electron band and an electric current runs. Accordingly, if the variation of this photoelectric current is detected and amplified by a DC amplifier 6 and registered by a recorder 7, the wavelength dependence of the photoelectric current can be measured, thereby enabling to know the existence of impurities with a deep level in the semi-insulating GaAs crystal.

Filed: 1986-09-03
Abstract: PURPOSE:To prevent damage of a reflecting mirror, by removing floating dust included in a gas medium, which is circulated to the reflecting mirror, through a filter, thereby avoiding the attachment of the dust to the reflecting mirror. CONSTITUTION:The inner surface of a filter 19 is fixed to the tip of a duct 16. The outer surface of the filter 19 is held by the ends of the inner surfaces of an adjusting member 3 and a flange 8. A part of the laser medium passes side flow ducts 17 and a communicating member 18 as a side flow. The medium passes the filter 19 at the tip of the duct 16 through a gap, which is formed by a hole 2A in an optical base plate 2 and the duct 16. The medium reaches a partial reflecting mirror 1 and flows into the discharge side through the inside of the duct 16 from the tip of the duct 16. Namely, floating dust is not included in the side flow reaching the reflecting mirror 1. Therefore, the dust is not attached to the inner surface of the reflecting mirror 1 and is not burned. Thus, damage of the reflecting mirror 1 is decreased, and the frequency of replacement can be made few.

Abstract: PURPOSE:To prevent the crush and thickness reduction of a product by forming a bulging part in advance on the part equivalent to the out side bending part of a blank and executing pressed forming via a core metal between the outside and inside forming dies. CONSTITUTION:A hydraulic bulge forming die 10 is provided in advance and a bulging part 2a is formed at the part equivalent to the outside of a bending part via the compression force by a high liquid pressure P and pressurizing levers 12, 13 on the blank straight pipe. Then formed hollows 23, 26 are respectively formed on an outside forming die 21 and inside forming die 22 and the preforming pipe 2 inserting core metals 28, 28 is set. In this state, an L type bend pipe 3 is subjected to press forming between both forming dies 21, 22 by descending the inside forming die 22 by a press cylinder. Due to the bulging part 2a being formed in advance at the outside part of the bending part, the thickness deviation necessary for the outside forming is executed. Consequently the crush and thickness reduction of a bend pipe 3 are thus prevented.
