Abstract: PURPOSE:To mechanize the exchange jobs between various types of currency and traveler's checks by performing the conversion of amounts among different types of currency based on the exchange rates shown by a CPU and printing various currency units and amounts to cope with each currency unit. CONSTITUTION:The data are processed by a CPU and a conversion rate and the next operating instruction is displayed on a CRT 3 with an instruction of the CPU. A customer confirms the exchange rate and puts a card or the yen notes into each slit. In a card process mode, an identification number and an amount to be drawn are inputted via a keyboard 4. Thus a dollar conversion amount and a yen amount to be drawn are displayed on the CRT 3. Then the customer confirms these two amounts and pushes a confirmation key, and a traveler's check producing machine 7 prints a designated currently unit and a designated amount under the control of a control part 1. Then the machine 7 pays a check and draws the corresponding amount out of the account of the customer. The same procedure is also available with the deposit of the yen notes. Then the checks and the change are discharged from the machine 7 and a coin discharging machine 6. Finally the details of the transactions are printed out by a magnetic card processing/receipt issuing machine 8.

Title: Core element for rotary transformer
Inventor: AIBA YOICHI
IPC: H01F38/14
Filed: 1993-06-18
Abstract: PURPOSE:To suppress warp at the outer peripheral part and over the entire element while restraining crack by forming the outer peripheral part in the polishing region of a core element thinner than other parts and providing circular flange type protrusions continuously to inclining faces on one and the other sides. CONSTITUTION:The outer peripheral part 2c in the polishing region of a core element 1 is formed thinner than other parts, i.e., the inner peripheral parts of inclining faces 4a, 4b on one and the other sides. Furthermore, circular flange type protrusions 5 are formed continuously to the inclining faces 4a, 4b on one and the other sides 2a, 2b. Since the difference of density is substantially eliminated in the protrusion 5 at the time of sintering the core element 1, the strength is not lowered at the outer peripheral part 2c and the warp is suppressed. This structure prevents crack and chipping and suppresses overall warp to keep flatness thus producing a core with high yield while preventing uneven baking on the other side.

Abstract: PROBLEM TO BE SOLVED: To improve a method of separating a material from a liquid mixture by fractional crystallization so that it may be executed by further lower investment and energy cost and with high reliability. SOLUTION: The inner walls of pipes in crystallizers S-1, S-2, S-3 are cooled by evaporating a liquid medium to form a crystal layer on the outer walls of the pipes, and then the crystal layer is melted. Heat energy may be supplied to the crystallizers in which melting is performed to evaporate the liquid medium and accelerate melting. The two crystallizers operating at the same time function respectively as an evaporator and a condenser in a refrigerating unit 11. In this way, a considerable amount of energy is saved compared to the well-known crystallization method.

Title: Sucking fixing type pal/rom writer
Inventor: OSHIMA YUTAKA
IPC: G11C17/00
Filed: 1992-06-09
Abstract: PURPOSE:To operate an insertion into a socket and a taking out from it when a sucking device fixing a PAL/ROM in the socket is stopped by interlocking the operation of a sucking device with a data writing and reading. CONSTITUTION:A PAL/ROM 1 is inserted into a socket 2 and when a writing switch 6 or a reading switch 7 is pressed, the operation switch 5 of a sucking device 3 is turned on and sucking is started. Thus, the pin of a ROM 1 is brought into contact with the contact of the socket 2 and fixed and then, data writing and reading are operated. When these operations are completed, the switch 5 is turned off, the device 3 is stopped and the fixing of the ROM 1 is released. Thus, the insertion and the taking out of the socket are operated while the device 3 is stopped and further, since a loading and an unloading are operated only by placing the ROM 1 or taking it out to the socket 2, many processings are operated.

Title: Picture memory device
Inventor: OKAMOTO ICHIRO
IPC: H04N5/907
Filed: 1990-06-06
Abstract: PURPOSE:To prevent the discontinuous phenomenon of a moving picture and to construct a compact frame synchronizer at low cost by providing a logic circuit to control a field memory in a dual port field memory, which can execute bidirectional transfer between a memory array and an output memory or an input memory, asynchronously inputting a moving picture video signal to the above-mentioned field memory and synchronously outputting the signal. CONSTITUTION:At the head of each frame, the phases of a V synchronizing signal on the input side is compared with the phase of a V synchronizing signal on the output side and when the difference is within 0.5H, a memory transfer instruction is transmitted three times during each H blanking period on the read side. First of all, a line data before 1H rather than an actual state is transmitted to a serial output buffer memory 1.6, and the data is immediately transferred to an idle line A1.4 of a memory array 1.3 (bidirectional transfer instruction). Next, the data saved before 1H is transferred from an idle line B1.5 of the memory array 1.3 to the output memory. By executing this operation during one field, the discontinuous phenomenon is prevented.
