Abstract: PURPOSE:To obtain a translucent separating wall material having high acid resistivity as well as radiation resistivity by using a molded body of a bridged methacarylic acid resin consisting of each specific constituent methyl methacrylic acid and bridging monomer, as the translucent separating wall. CONSTITUTION:A molded body of bridged methacrylic acid resin consisting of 60 to 98 wt.% methyl methcrylic acid unit and 2 to 40 wt.% of bridging monomer unit, is used as a translucent separating wall material 1.

Title: Liquid feed pump
Inventor: MARUYAMA SHUZO
IPC: F04B49/06
Filed: 1989-05-31
Abstract: PURPOSE:To automatically recover a pulse motor when it has a loss of synchronism by providing a motor stop detecting unit temporarily decreasing the frequency of the pulse signal sent from a pulse signal generating unit to a pulse motor driving circuit when the stop of the pulse motor is detected. CONSTITUTION:When a pulse motor 8 has a loss of synchronism from some cause, no output signal detecting the rotation is sent from a sensor 10. The pulse signal with the fixed frequency is outputted from a pulse signal generating unit 2 at this time, thus a motor stop detecting unit 12 detects that the pulse motor 8 is stopped. When the motor stop detecting unit 12 detects the stop of the pulse motor 8, the pulse signal generating unit 2 temporarily decreases the frequency of the pulse signal sent to the pulse motor driving circuit 6 via the output from the motor stop detecting unit 12 then gradually returns it to the original frequency. When the rotating speed of the pulse motor 8 is decreased, it can be recovered from a loss of synchronism.
