IPC: G06K7/08
Filed: 1984-09-27
Abstract: PURPOSE:To detect the number of magnetic cards entered into an input storage box precisely by arranging a magnetic card input detecting means on the back of a magnetic card reader. CONSTITUTION:When the back end of a magnetic card passes on an input carrying completion detecting circuit 18, an entered card No. counter is counted up from '0' to '1' on the basis of a signal outputted from a magnetic and input detecting circuit 32. In the input operation of the 2nd magnetic card or after, said counter in an input control part 4 is counted up at its counting value by an output obtained when the back end of the magnetic card passes the circuit 18. Consequently, the number of magnetic cards stored in the input storage box 3 is stored in the counter of the control part 4. The counted value is compared with the number of cards to be stored in the box 3 which is set up in a stored card number setter to detect that the box 3 is filled with the cards.

Title: Improved casting method for reactive metal against surface formed from improved slurry containing yttria
Inventor: ROBAATO EI HOOTON
IPC: B22D11/00
Filed: 1990-08-01
Abstract: PURPOSE: To prevent the occurrence of cracking or pulverizing during the baking and in casting a reactive metal by engaging a surface area generated by a slurry and a molten reactive metal without generating gelation in a stage when the molten reactive metal is poured into a mold. CONSTITUTION: The slurry is prepared by mixing a water-base binder having yttria with a hydroxyl ion source. Immediately after the mixing, the slurry has a very high pH value, but the pH value is rapidly reduced, and, for example, in six days, the pH value of the slurry is reduced, and relatively stable. The slurry against the gelation is mixed, and used for several mounts while a large number of molds and cores are substantially and continuously manufactured. The manufactured molds have a surface generated from the slurry. The molds are neither cracked nor pulverized during the baking. This shows that there in neither interaction of the hydroxyl ion with yttria, nor hydration of yttria.

Patent JP-H0253190-A (JP)
Title: Bar code detector
Inventor: NAKASUJI AKIO
IPC: G06K7/00
Filed: 1988-08-18
Abstract: PURPOSE:To allow an analog signal to be always between the high level and low level of a binarization signal and to execute exact binarization by obtaining a signal to load hysteresis to the peak holding circuit output of a floating binarization circuit from the power source voltage of a comparator. CONSTITUTION:An analog signal A executes the charge/discharge of a capacitor 4 and generates a comparing reference value B. The comparing reference value B is inputted to a non-inverting input D of a comparator 1. Since the comparing reference value B is passed through a diode 2, the change of a signal is delayed to the analog signal A only by the dead zone part of the diode. Thus, when the analog signal A is changed from a peak by the dead zone part, the analog signal A and the comparing reference value B are across and the output of the comparator 1 is switched. Since the output of the comparator 1 is pulled up by the power source of the comparator 1, a binarization signal C is switched at the power source voltage level of the comparator 1. When the binarization signal C is switched, the hysteresis is loaded through a resistor 5 for hysteresis to the non-inverting input D and the binarization signal C is prevented from being oscillated.

Title: Fiber optical amplifier
Inventor: HAABAATO JIYON SHIYOO
IPC: H01S3/23
Filed: 1984-09-28
Abstract: @ A pair of small diameter optical fibers (12, 14) are arranged in a side-by-side configuration, the first fiber (12) providing a passive guide for pump light, and the second fiber (14) formed of a material, such as Nd:YAG which has amplifying properties at the signal frequency. The signal to be amplified propagates through the second fiber (14) resulting in amplification of the signal. The first fiber (12) is pumped from one or both ends, utilizing a cone shaped rod (50) which is optically coupled thereto. A plurality of pump light sources (60) are mounted on the end face (58) of the rod (50) to introduce collimated pump light into the large end (52) of the cone shaped rod (50). Total internal reflections on the cone walls compress the pump light to a small, fiber-size diameter end (54) for propagation through the pump fiber (12) and absorption by the active fiber (14). The pump light sources (60) are offset from the axis (72) of the rod (50) to excite high order modes in the pump fiber (12) to enhance absorption by the active fiber (14). The pump light sources (60) preferably comprise high power laser diodes (64) and collimating microlenses (62). By utilizing the cone-shaped rod (50) to couple light from the high power laser diodes (64) to the pump fiber (12), high pump power densities can be achieved, yielding increased amplification.
