Abstract: PURPOSE:To increase the capacity of the device and speed up data processing by equipping the information recording device with a data compressing/ expanding mechanism. CONSTITUTION:When the compression of data is set from a compression setting input means 900, a control means 200 records a compression identifier in a specific area on a recording medium through a compression identifier generating means 1100 at the time of formatting. A compression identifier detecting means 1000 decides which of compressed data and uncompressed data are recorded on the recording medium by detecting the compression identifier and the operation of the expansion selecting means 700 and a compression selecting means 800 is controlled with the output signal of the detecting means 1000. Namely, when the compression identifier is detected, an expanding means 600 and a compressing means 500 are selected. When the compression identifier is not detected, on the other hand, the data are stored in a data storage means 300 through neither the expanding means 600 not the compressing means 500.

Filed: 1983-11-29
Abstract: PURPOSE:To record information without increasing the number of tracks neither degrading the recording efficiency by recording a main signal and an auxiliary signal on the same track on time division basis at intervals of a certain time. CONSTITUTION:A time data generating circuit 7 counts the number of reference clocks by an incorporated counter and latches the counted value at intervals of a certain time and outputs it as time data.

A time division circuit 5 is switched and controlled by a switching control signal outputted from a switching pulse generating circuit 8 to insert the auxiliary signal obtained from the time data generating circuit 7 in the blanking period of each main signal obtained from a modulating circuit by the time division circuit 5, and both signals are synthesized, and they are recorded on the magnetic tape through a recording circuit 9 in the next stage and a recording head 10. Thus, information is recorded with a small number of magnetic heads, and tracks on the magnetic tape are used effectively.

Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To realize the reduction of the generation of a stripelike pattern by fixing coloring density by a method wherein an application time and either one or both of voltages are made variable in response to the difference between the resistance values of both elements adjacent to each other so as to equate the printing energy given to the resistance heating element corresponding to each element driving circuit with that given to the adjacent element. SOLUTION: By driving a driven IC 20 so as to successively select one resistance heating element among a series of resistance heating element train and by applying an A-phase power source or a B-phase power source, both having a constant voltage, so as to measure the current flowing through the selected resistance heating element in order to fine out the resistance value of the selected resistance heating element from the measured current.  The above-mentioned measurement is successively performed to the whole resistance heating element so as to calculate the difference between the resistance value of the subject element and the of the adjacent element in order to find out the resistance correction value on the basis of the calculated difference, resulting in housing the resistance correction values together with the order number of the corresponding resistance heating elements in a resistance value memory 21. On the basis of this correction data, the application time, which varies in response to the difference between the subject resistance heating element and its adjacent resistance heating element, is given to respective resistance heating elements so as to allow to give equal printing energy to the respective resistance heating elements.

Filed: 1984-10-31
Abstract: PURPOSE:To transmit much identification information without expanding a multiplex sound signal band to high frequencies by setting the identification signal to a frequency band less than the audible frequency band. CONSTITUTION:Identification signal oscillators 1a-1c are set to output an ultralow frequency signal less than the audible frequency band respectively. Then the identification signal selected by a switch 2 amplitude-modulates 3 a carrier signal 4 having a frequency less than the audible frequency band to obtain an amplitude modulation identification signal. After the amplitude modulation identification signal is mixed to the sound signal by mixing circuits 7a, 7b, the sound signal is transmitted by using a high frequency carrier. On the other hand, the signal is demodulated at the reception side to extract an identification signal. Thus, much identification information is transmitted without expanding the multiplex sound signal band toward high frequencies.

Filed: 1990-08-30
Abstract: PURPOSE:To linearly change the output current of a current control circuit by making the output signal of a D-A converter a temporary minimum value during the switching control of a standard resistor. CONSTITUTION:A code for continuously changing the output voltage of a D-A converter 12 in a range from its maximum value to 1/10 and a code for changing output current I0 by one figure by switching switches RY1-RYn are generated in a control signal generation part 10.

Title: Articifial magnetic lattice film
Inventor: SENDA MASAKATSU
IPC: H01F10/32
Filed: 1987-09-14
Abstract: PURPOSE:To obtain an artificial magnetic lattice film which exhibits a high saturated magnetic flux density and good soft magnetic characteristics, also has a magnetostriction constant substantially equal to zero, and simultaneously is excellent in corrosion resistance and thermal stability, by alternately stacking on a substrate a Fe layer and a Co layer and/or a CoFe layer so that they have a periodic structure by repetition. CONSTITUTION:Four targets can be mounted on a target supporting stand 1, which can be rotated to switch the targets. There are a position at which a substrate is to be placed, on the upper surface of which substrate magnetic films are to be stacked and formed, and an ion source 3. The manufacture by an ion beam sputter method is advantageous in that the operating degree of vacuum is 1X10<-4>Torrs or less and the substrate temperature does not increase more than required. A Co layer 4, Fe layer 6, and CoFe layer formed by mutual diffusion are formed on a substrate 7. The film thicknesses of the Co layer 4 and Fe layer 6 are tCo and TFe, respectively, and one period tP of the artificial lattice is defined by an equation tP=tCo+tFe. The artificial magnetic film can thus accomplish good soft magnetic characteristics and simultaneously can achieve a high saturated magnetic flux density. Also, these magnetic artificial film has a construction wherein Fe is with respect to Co and/or CoFe, so they are rich in corrosion resistance and the magnetic characteristics are not degraded, providing excellent thermal stability.

Title: Signal processing method for hot wire flowmeter
Inventor: TERAGAKINAI AKIRA
IPC: F02D41/00
Filed: 1985-10-16
Abstract: PURPOSE:To improve engine control precision by inputting the reference potential signal of a hot wire flowmeter to the A/D converter in a controller and correcting the output voltage, and calculating the accurate quantity of sucked air on the basis of the information after correction. CONSTITUTION:An operational amplifier 9 is incorporated in the hot wire flowmeter 1 and operated at a reference potential 4, but this potential 4 is VG=IR higher because of a current I which flows from the resistance 7 in wiring and the meter 1 to the earth potential 8 of a battery 10 through a potential 4. Therefore, the output voltage 5 of the meter 1 becomes Vout which is the sum of a voltage VQ based upon the quantity of sucked air and said VG and the earth potential of the A/D converter 3 in the controller is not equal to the potential 8 because the current in the wiring 11 is small. Therefore, it is considered that the quantity of sucked area which is the voltage VG larger than the actual voltage VQ, so the potential 4 of the meter 1 is inputted to the converter 3 by using the wiring 6 to obtain the voltage VQ corresponding to the actual quantity of sucked area as information for engine control.
