Abstract: PURPOSE:To pull out generated ions effectively into an analysis space with no quenching in an ionization chamber by a method in which a recessed part formed for being connected through with an ion pulling-out port in order to be composed so that lines of electric force generating from the surface of an ion pushing-out electrode may concentrate on said recessed part. CONSTITUTION:A chamber 17' for housing a trap 18 is located in the position facing an electron shooting-into port 14 inside an ionization chamber bloc 11, while the trap 18 therein is mounted electrically insulated against the ionization chamber bloc 11. The recessed part 21 formed by hollowing out the inside wall surface leads to the ion pulling-out port 13. The concentration of generating ions can be heightened by performing ionization of sample gas in said recessed part 21. Further, a sample introducing entrance 12 is provided in the rear of the ion pushing-out electrodes 19 and 19' so that a vector in the direction of sample flowing-in from the arrow direction and a vector in the direction of pulling out ionized ions are united to pass through a narrow slit formed between the halved ion pushing-out electrodes 19 and 19' thus improving the ion pulling-out efficiency.

Title: Lid unit for apparatus
Inventor: IKEDA YOSHIO
IPC: D06F39/12
Filed: 1989-03-25
Abstract: PURPOSE:To prevent damages to a rotating spindle even when an excess force is exerted on a lid that is in open state, by a method wherein an opening is formed on a bearing part connecting to a bearing hole, its opening direction is along with the rotating direction of the lid when it is opened, and the rotating spindle is press-fitted into the bearing hole through the opening. CONSTITUTION:When a lid 9 is opened, a rear side wall 10 of the lid 9 comes in contact with a stopper 16 so that the rotating angle is restricted. In this state, if a force is exerted on the lid 9 to open the lid 9 further, a force around the stopper 16 as a pivot in the same direction is exerted on a rotating spindle 13 owing to the action of levers. At this time, the rotary spindle 13 gets out bearing holes 14a of bearing parts 14 and 15 through an opening 14b when the force exerted on the rotating spindle 13 exceeds a certain value since an opening 14b is provided on the bearing parts 14 and 15, and its opening direction is along with the rotating direction of the lid 9 when it is opened. Thereby, the rotating spindle 13 is prevented from receiving an excess force and being damaged unlike conventional lids.

Title: Power supply controller of pump motor
Inventor: SHIZURU YOSHIHIRO
IPC: A47J31/46
Filed: 1991-03-11
Abstract: PURPOSE:To obtain a power supply controller of a pump motor which does not repeat drive and stop even if the water level varies due to the backflow of water in the pipes, by stopping power supply to the pump motor regardless of the water level after the water level in the water tank has lowered to the level at which the pump can not suck the water. CONSTITUTION:Since current is conducted to an electromagnetic coil of an electromagnetic relay X2 when a float switch 36d is closed, a b-contact X21 is opened to open the power supply circuit of an electromagnetic relay X1. But the electromagnetic relay X1 holds a current-conducting state against the self electromagnetic coil by closing an a-contact X12 parallelly connected with the b-contact X21, when the current is previously conducted. Therefore, even if the electromagnetic relay X2 opens the b-contact X21 interposed in the power supply circuit of the electromagnetic relay X1, the current condition of the relay X1 is not changed and hence, the b-contact X11 of the relay X1 interposed in the current feed line of the pump motor 35b is kept open. Accordingly, current is not conducted to the pump motor 35b and hence, the motor cannot be driven or stopped repeatedly.
