Title: Safety device to detect disconnection in automatic speed- change control system
Inventor: IMAI NOBUYUKI
IPC: B60K20/00
Filed: 1980-07-24
Abstract: PURPOSE: To generate an abnormal voltage signal at the time of disconnection in the output signal line of a car-speed response signal by connecting resistances in parallel with a switch to issue constant-voltage pulses as responding to car speed.  
     CONSTITUTION: A lead switch LSW in a lead-switch type car-speed sensor 31 is connected to the input terminal of an FV conversion circuit in the (+) side and earthed to a car in the (-) terminal. The lead switch LSW is switched on or off by the frequency responding to the car speed, and send out a constant-voltage pulse signal V'L 1  to a terminal L by a circuit construction in which the lead switch is connected in parallel with resistances R 2 , R 3 , and R 4  connected in series with a resistance R 1 . When a resistance RL is connected to both terminals of the lead switch in parallel, voltage is dropped in the terminal L to issue a low signal voltage VL 1 . When a wire breaking BR is given at this stage, the voltage at the terminal L is brought to VL 2 . Meanwhile, at the normal state of car stoppage ST, the voltage at the terminal L is brought to VL 1 (ST) or "0".

Abstract: PURPOSE: To manufacture MnCl 2  of superior quality by neutralizing a soln. of ferromanganese slag in sulfuric acid to remove impurities, adding CaCl 2  to the resulting soln., concentrating the soln. to remove CaSO 4  deposited, and further concentrating the soln.  
     CONSTITUTION: Sulfuric acid is added to an aqueous slurry of ferromanganese slag finely pulverized to ≤200 mesh to dissolve the slag, and this soln. is adjusted to 6.0W8.5pH with alkali. By blowing air or oxygen-contg. gas, divalent iron is converted into trivalent iron, and the iron and heavy metals are precipitated as hydroxides, which are separated by filtration. To the filtrate is added an aqueous CaCl 2  soln. in an amount required to convert MnSO 4  and ZnSO 4  into chlorides, and the filtrate is concd. just until MnCl 2  crystals begin to deposit. After removing CaSO 4  deposited by filtration, the filtrate is further concd. to crystallize MnCl 2 . This MnCl 2  is centrifugally separated and washed. The washing liq. is discharged from the system. Thus, MnCl 2  crystals are obtd.

Title: Driver's cab display device
Inventor: TAKAHASHI TORU
IPC: B61L25/02
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To grasp the advancing state of a train without calculating the time by a driver itself by regularly calculating the train operating state to a timetable and continuously displaying the result in a driver's cab display device. SOLUTION: A pulse generator 12 is mounted on the wheel 11 of a train. Since the pulse is generated in proportion to the rotating number of the wheel 11, or the advancing distance of the train, and counted in a counter 13, the output value of the counter 13 shows the position from the starting point of the train when the counter 13 is reset in the starting point of the train. When this position is inputted to a timetable 14, the scheduled time corresponding to the position is determined. On the other hand, the present time is outputted from a clock 15, and a time deviation or 'the scheduled time - the present time' is calculated in an adder 16. According to this calculated, the pointer of an operating state indicator is moved.
