Title: Removal of carbon monoxide from carbon monoxide- containing gas consisting essentially of oxygen
Inventor: NISHIZAWA YASUO
IPC: C01B32/40
Filed: 1984-01-31
Abstract: PURPOSE:To remove Co contained in gaseous O2 almost completely without deactivating a catalyst by allowing gaseous O2 contg. CO to contact with a catalyst comprising partly reduced copper oxide and zinc oxide. CONSTITUTION:CO-contg. gas consisting essentially of O2 is allowed to contact with binary catalyst consisting of a combination of partly reduced copper oxide and zinc oxide. The proportion of the components of said catalyst is 10-40, pref. 20-40wt% CuO to 90-60, pref. 80-60wt% ZnO. In the above described process, small amt. of CO contained CO/O2 mixture is reacted with O2 to be converted to CO2. Since the reaction of O2 with CO is exothermic, a fixed temp. is maintained by the own heat of combustion, supply of external heat is unnecessary, or if any, only a little.

Abstract: PROBLEM TO BE SOLVED: To enable a high-reliability counting management, by collecting and managing paper moneys defective in detection or paper moneys defective in identification into a paper money replenishing and collecting device when these unsuitable paper moneys are detected in replenishing paper moneys. SOLUTION: Paper moneys A housed in cartridges 74a-74c by denominations are conveyed through a replenishing route 76 to a replenishment connecting part 72 at the time of replenishment and replenished on the side of paper money processor 11 while identifying their denominations and numbers through an outline detection part 78 for outline check arranged in the middle of conveyance.

Title: Wash stand with shower
Inventor: TSUSAKA HARUNARI
IPC: E03C1/14
Filed: 1989-01-26
Abstract: PURPOSE:To allow a foreign object or a finger to be immediately removed when pinched by detecting the load of a water feed pipe when it is vertically moved and controlling a driving source to stop the water feed pipe after it is lifted when the load of the water feed pipe during its descent becomes the preset value or above. CONSTITUTION:When a descent switch 18 is turned on, whether the limit switch SW3 at the descent position is on is judged, if it is off, a motor 5 is rotated to lower a water feed pipe 3, and time counting is started. When the descent of the water feed pipe 3 is started, a fluctuation occurs in the current to the motor 5, thus no load detecting processing is performed for 0.3sec, for example, to allow descent. When an overload is detected after this time elapses, the motor 5 is reversely rotated for a fixed time to raise the water feed pipe 3. When no overload is detected, the motor 5 is stopped when the limit switch SW3 is turned on at the lowest position. When an overload is applied, the motor 5 is reversely rotated to raise the water feed pipe 3, even if a foreign object or a finger is pinched between the water feed pipe 3 and a guide tube 16, it can be immediately removed.

Abstract: PURPOSE:To remove completely residual resin and to make after treatment easier, by closing completely a nozzle at a measuring time and discharging a purging resin through the inside of a nozzle touch plate at a purging time. CONSTITUTION:After a contacting part 25A of a nozzle touch plate 25 is moved in such a manner that it comes on a line X, a nozzle 21 is brought into contact with the contacting part 25A by forwarding a barrel 22, and a measurement is carried out in such a condition that a purging resin does not flow in a resin path 25C by closing a valve 51.

CONSTITUTION:A separating device 7 is conveyed to the upper portion of a piled boards and lowered by means of an unshown elevating device, and needles 5 provided on the bottom face of absorbing cups 3 are stuck to the piled boards. At this time, the needles 5 are stuck to a board material on the top portion out of the piled boards. Then, the separating device 7 is laterally moved and, after shifting only the top board material from the piled boards, air is sucked upward via a suction pipe 1 to adsorb the board material on the top position to the adsorbing cups 3. At this time, since the adsorbing area of the second board material is reduced due to the laterally moved separating device 7, the adsorbing force is unable to lift up the second board material, thereby, lifting up only the board material on the top portion. After that, the board material is conveyed to a defined position on the following process.
