Title: Dc motor driving circuit
Inventor: SHOJI MOTOHIRO
IPC: H02P7/288
Filed: 1990-11-28
Abstract: PURPOSE:To improve the accuracy in overcurrent detection by changing the detection level of the overcurrent of a motor according to the driving time of the motor. CONSTITUTION:When a motor start signal b is input, a switch SW is opened, and a capacitor C starts the charge by the current from a power source Vcc, and with the passage of time since the input of the motor start signal, the capacitor C is charged, so the detection level of the motor overcurrent changes by the time from the start. And the output voltage of the emitter of a transistor Tr is input to the positive terminal of a comparator COM, and the detection voltage Vth is input to the negative terminal P. Accordingly, the comparator COM compares these voltages, and when the emitter voltage of the transistor Tr exceeds the detection voltage Vth of the emitter voltage of the transistor Tr, it generates an alarm signal AL.

Title: Reagent for turbidmetry determination of potassium
Inventor: IDA SHUZO
IPC: G01N21/83
Filed: 1988-12-21
Abstract: PURPOSE:To improve analysis accuracy and to make reliable quantitative analysis of potassium by using a reagent consisting of the 1st agent contg. sodium tetraphenylboron and the 2nd agent contg. an anionic surfactant. CONSTITUTION:The sodium tetraphenylboron forms a hardly soluble precipitate by reacting respectively with alkaline metal ions exclusive of Li<+>, Na<+>, and NH4<+> and its deriv., and monovalent metal ions but do not form the precipitate with polyvalent metal ions. The disodium ethylenediaminetetraacetate which is the component of the 2nd agent acts as the masking agent for disturbing ions and formalin acts as the decomposing agent of ammonium ions. An anionic surfactant consisting of an aq. sodium carbonate salt soln. of arom. hydrocarbon lowers the solubility of the reaction product to disintegrate the precipitate to fine particles. The rapid measurement with the simple operation is thus executed by the turbidmetry analysis using the reagent consisting of the 1st agent and the 2nd agent. The determination of the potassium with the high reproducibility and high measurement accuracy is executed.

Inventor: YAMADA TSUTOMU
IPC: C09G1/00
Filed: 1988-12-22
Abstract: PURPOSE:To prepare a polishing cleaner compsn. capable of removing the soils and stains attached firmly or penetrated into a surface layer without degrading the appearance of a polished surface by compounding a cleaner base material with a grinding abrasive grain, boehmite or pseudoboehmite. CONSTITUTION:A polishing cleaner compsn. is obtd. by compounding a cleaner base material with a grinding abrasive grain, boehmite or pseudoboehmite.
