Abstract: PURPOSE:To change the direction of paper and invert it during the movement of a pair of belts, by pinching the paper between the pair of belts moving in a direction. CONSTITUTION:Paper 1 is inserted through a paper inlet port 13 defined by insertion rollers 101, 201, so that the paper is carried in a first pinching conveyance passage to a direction changing roller 301 as the paper is pinched between an upper and a lower belts being in contact with each other.

Title: Underwater transmitter
Inventor: MORIKAWA SHIYOUHEI
IPC: H04R1/44
Filed: 1981-07-22
Abstract: PURPOSE:To allow a speaker to execute a specified performance, by subjecting an internal water pressure to follow after an external water pressure even if the depth is remarkably changed. CONSTITUTION:A transmitter 18 is provided with a speaker consisting of a diaphragm 13, a magnet 17, a coil bobbin 16 and a coil 14 and driven with a signal from a cable 19. The internal part of the transmitter 18 is connected to an air chamber 4 with a link tube 12. When a diaphragm 11 is displaced up and down with an external water pressure and it is located between magneto-sensing elements 21 and 22, the pressure in the air chamber is equal to the external pressure. Thus, the pressure in the transmitter 18 is equal to the external pressure. If the diaphragm 11 is located above the element 11 or below the element 22  with a large external pressure, the internal pressure can not follow the external  pressure. If the external pressure is larger, a valve 3 is controlled to supply air in a high compressed air tank and if smaller inversely, a valve 8 is controlled  to blow out air externally, allowing to set the position of the diaphragm 11 to  the position of an element 20.

Title: Data secrecy system
Inventor: OOZEKI YOSHIAKI
IPC: H04L9/00
Filed: 1980-08-20
Abstract: PURPOSE:To increase the ability of secrecy, by converting the original data every bit length at random. CONSTITUTION:An input data signal train A to be transmitted is transmitted to a reception section (not shown) as an output data via a generation polynomial operation section 6 divided with an indefinite logical equation. A clock signal inputted to the section 6 is counted at a clock counter 1 and it is compared with the number generated from a random number generator 3 at a comparator 2. When the both are in coincidence, the adderss value of an address counter 4 is increased by 1 to change the output of a generation polynomial random mode generating section 5 and the generation polynomial of the section 6. Thus, the data train A is changed with a logical equation making division every random number produced from the generator 3 and given to the reception side. The multiplication at the reception side with the same logical equation as that at the transmission side can reproduce the input data signal train A.

Abstract: PURPOSE:To eliminate the need for entry by an operator or an applied job program on each transmission for a medium kind whose destination is able to be received in an electronic medium delivery equipment such as an electronic mail equipment handling plural kinds of media. CONSTITUTION:An electronic medium delivery equipment is provided with a medium kind recording section 103 recording and managing a destination of a delivery destination and a type of an electronic medium able to receive the destination.

As a result of retrieval, only when the destination is not found out, the type of the electronic medium received by the destination is designated externally and a medium type learning section 106 records the type onto the medium type recording section 103. Since the operator and the applied job program have only to designate the medium type once at first, the load is relieved.

Title: Coil driving circuit
Inventor: KANOU KENJI
IPC: H03K17/64
Filed: 1982-06-30
Abstract: PURPOSE:To obtain easily a small-sized, compact integrated structure, by connecting a Zener diode between the base and collector of a transistor (TR). CONSTITUTION:When the base-emitter voltage of the TR1 is VBE, the collector voltage of the TR1 is limited to VZ+VBE(VZ: breakdown voltage of Zener diode). Then, when the impedance of a signal source connected to the input of the TR1 is sufficiently high while an input signal is in a low level state, the current flowing through the TR1 is nearly VCC/R (where VCC is a power supply voltage and R is the resistance of coil) at the moment the TR1 is transfered from turned on state to off state. Further, the current flowing through the Zener diode 31 is VCC/hFE.R, where hFE is the common emitter current amplification factor of the TR1. Consequently, the current flowing through the Zener diode 31 is reduced to extremely small, so a small-sized element is usable.

Abstract: PURPOSE:To easily attain the demodulation of an MFM data, by deciding whether a synchronizing signal exists in an MFM signal or a data signal when it is received by a processor, and sending out a control signal to a data signal separation circuit corresponding to a decided result. CONSTITUTION:A sync signal is attached on the MFM signal as a signal for synchronizing.

At the microprocessor 16, the data is decided, and when it is sync signal, a data window signal is left as it is, and the data is received successively. When it is not the sync signal, it is decided that a synchronization between the MFM signal, and the data window signal, is not taken, and an inversion instruction signal for the data window signal is inverted from an off-state to an on-state, then it is sent onto an inversion instruction signal line 17.
