Title: One-dimensional mapping circuit
Inventor: SHONO KATSUFUSA
IPC: G09C1/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a one-dimensional mapping circuit on an integrated circuit and to improve the state decision accuracy of circuit output by turning a CMOS source follower to the depletion mode and turning a CMOS inverter to an enhancement mode. SOLUTION: The CMOS inverter applies transmission characteristics with which an output voltage decreases against the increase of an input voltage. The CMOS source follower, for which the CMOS inverter is inverted between a power source and the GND, applies voltage characteristics with which an output voltage increases corresponding to the increase of an input voltage. Concerning the CMOS inverter and the CMOS follower, the input is commonly applied, the output is commonly connected, and non-linear input/output transmission characteristics synthesizing decrease and increase functions are provided. In order to control non-linearity from the outside, external biases are respectively applied. Since the CMOS source follower is set to the depletion mode and the CMOS inverter is set to the enhancement mode, channel sizes are equalized and the state decision accuracy is made equal.

Title: Ic card
Inventor: MIZUTA TAKASHI
IPC: G06K19/07
Filed: 1989-04-27
Abstract: PURPOSE:To reduce the probability of a contact failure and to improve the reliability of data communication by superposing a carrier signal modulated by transmitting/receiving data on a plus power source. CONSTITUTION:On a plus power source S1 supplied form an external apparatus 1, a carrier signal is superposed by an adder 13, a signal S2 passes through an analog switch 16 and synchronizes with transmitting data S3 and a carrier component is attenuated by an HPF 17, and an amplitude modulation is applied. By this procedure, the transmitting data is superposed on the plus power source. In an IC card 2, by allowing the plus power source obtained form a contact terminal 18A to pass through a first LPF 6, a carrier signal component is elimi nated. This signal S4 is brought to level shift by a waveform shaping device 8, and thereafter, converted to a digital signal S5, and sent as receiving data to a microprocessor. The LPF 6 cuts off enough a carrier signal frequency. The signal S4 is furthermore eliminated almost completely as to its data compo nent by a second LPF 7, and supplied as a DC power source to the microprocessor 3 or a solid-state memory 4. By this procedure, the IC card 2 demodulates the receiving data.

Abstract: PURPOSE:To prevent voice of a speaker from introducing crosstalk to a microphone by placing a speaker to a position where sound is received omnidirectionally within a plane including 2 directivity microphones or over and the sensitivity is minimized and making the direction coincident with the sound transmission direction. CONSTITUTION:The device consists of a main body 2 having a speaker 1 for talking and one sub case 3 or over removable therefrom, and two directional microphones 10, 11 or over are mounted to the one sub case 3 or over. In this case, the device is configurated such that it is possible for nondirectivity sound reception within a plane including the directivity microphones 10, 11, the position minimizing the sensitivity is a position of the said speaker 1 and the direction minimizing the sensitivity is made coincident with the sound transmission direction of the speaker 1. That is, the directivity 6 within a plane including >=two microphones 10 is omnidirectional in this arrangement and a region 62 is a region where its sensitivity is minimized in a direction at a right angle with respect to a face including the two microphones 10 or over. Thus, the sound from the speaker 1 does not introduce crosstalk to the microphones 10.

IPC: B41J2/165
Filed: 1980-08-08
Abstract: PURPOSE:To provide a low energy consuming type printer wherein a capacitive electromechanic transducer for opening or closing a lid for an ink jet nozzle is provided, and the opening or closing is actuated in response to the on or off of an electric source of the printer. CONSTITUTION:The opening or closing of the lid 6 for the ink jet nozzle 1 of the ink jet type printer is effected by the actuation of the capacitive electromechanic transducer (for example a piezoelectric element) 4, whose actuation is effected in response to the on or off of the electric source 8. For instance, if the electric source 8 is connected to a capacitor 13, since the capacitor 13 will be charged when the electric source is applied, it is only enough to charge the amount discharged by a self- discharge resistor 14 having a very high resistance, and therefore the energy is required less.

Abstract: PURPOSE:To improve the quality of the direct read-after-write signal with a simple and inexpensive structure by providing a circularly arcuate magnetic material of high permeability at the outer circumference of a rotary head rotor along the nonmagnetic side of a magnetic tape. CONSTITUTION:A circularly accurate magnetic material 11 of high permeability is provided at the outer circumference of a rotary head rotor 2 along the nonmagnetic side of a magnetic tape. At first, the tape 1 and the rotor 2 are driven and then a reproduction amplifier circuit 15 is actuated while the record signal is impressed from a record signal input terminal 13 via a record amplifier circuit 14. Thus the information is recorded on the tape 1 and at the same time the direct read-after-write signal is obtained at a reproduction signal output terminal 16. This signal has an extremely reduced level of cross feed noises and an extremely small time delay to the record signal. Thus the quality is improved for the direct read-after-write signal with a simple and inexpensive structure.
