Title: Magnetic head
Inventor: MORI NOBORU
IPC: G11B5/127
Filed: 1986-03-28
Abstract: PURPOSE:To minimize the interval between a recording and reproducing gap and an erasure gap by installing magnetic cores having specific azimuths on both sides astride a magnetic core having a reproduction coil. CONSTITUTION:A magnetic core block 10 to record, reproduce and erase data has the R/W (recording and reproducing) gap 1 and the E (erasure) gaps 2a and 2b. The block 10 is wound with a recording coil 30 and the reproduction coil 40. Since in this constitution the gaps 2a and 2b have azimuths theta of 45 deg. with respect to the gap 1, an increase in the peak shift of a signal recorded by the gap 1 is significantly minimal because a magnitude to reproduce a recording signal in an azimuth recording area from the gap 1 at the time of reproduction is extremely minimal. With this constitution a time margin even in an off-track can be satisfactorily recognized. Although the azimuth was to be 45 deg., it may be within a range of 5-60 deg..

Title: Character string generation system
Inventor: ARIO TAKENOBU
IPC: G06F12/00
Filed: 1989-03-20
Abstract: PURPOSE:To eliminate the need for confirmation processing for repetition and to generate a character string wherein characters, etc., can be mixed by generating a character string consisting of a specific number of digits by utilizing a date and a time and extracting usable characters in the order corresponding to an object value as the corresponding character string. CONSTITUTION:The date and time at the start of character string processing are coupled by a coupling part 15 to obtain a character string, which is divided by an arithmetic part 16 into character string sections. The arithmetic part 16 divides the numerals that the character string sections indicate by the number of usable characters to obtain conversion values, whose integer parts are extracted; and the products of the integer parts and the number of usable characters are subtracted from the numerals that the character string sections indicate to calculate the object value. This object value is supplied to a character extraction part 17 to extract one character in the order corresponding to the value among the usable characters. The calculation of the object value and the character extraction are carried out for each obtained character section. Consequently, the confirmation processing for repetition is not necessary and the character string wherein characters, etc., can be mixed can be generated.

Title: Control circuit for frequency temperature characteristic of oscillating circuit
Inventor: NONAKA SATORU
IPC: H03B5/32
Filed: 1980-05-23
Abstract: PURPOSE:To realize an optimum control for the frequency temperature characteristics of an oscillating circuit, by connecting a parallel circuit of capacitors and a switching circuit in series to at least one of plural oscillators. CONSTITUTION:The on/off of a switching circuit 121 is controlled by a duty ratio control circuit 3, and the signal to control the duty ratio of the circuit 3 is delivered from a frequency dividing circuit 2. The oscillation frequency varies with variation of the capacities of capacitors C1 and C2. Thus the oscillation frequency is reduced by increasing the capacity and vice versa. For instance, a quartz oscillator X1 and the capacitor C1 are excluded from an oscillating circuit 12, and the oscillation frequencies are referred to as f1 and f2 when the circuit 121 is off and on respectively. Thus the oscillation frequency can be controlled in a range from f1 through f2, by controlling the time during which the circuit 121 is turned on.

IPC: G11B5/17
Filed: 1985-04-03
Abstract: PURPOSE:To decrease remarkably crosstalk by providing a conductor wound reversely to each coil so as to section two coils. CONSTITUTION:A structure is adopted that leads 1, 2 continued to coils 5, 6 are placed between coils 5, 6 so as to form conductor parts 7, 8 sectioning the coils.

The electromotive force caused by the leaked magnetic flux, however, is cancelled by the electromotive force by the conductor 7 and other part because of the presence of the conductor 7 between the both and very small. The similar result is obtained as to the left coil 6.

Filed: 1988-03-25
Abstract: PURPOSE:To improve resolution and yield by connecting the gate electrode and source electrode of a thin film transistor(TR) to a gate bus and a reference bus respectively, providing a picture element electrode opposite plural data buses in a straddling state and connecting the drain electrode to the picture element electrode. CONSTITUTION:A gate bus 4 selects a display line and connects the picture element electrode 8 formed of a transparent conductive film connected to the drain electrode 17 of the thin film TR electrically to a reference bus 6. When a display signal voltage is applied to a data bus 2 formed on an opposite substrate surface, a voltage is applied between the data bus 2 that the picture element electrode 8 straddles opposite and this picture element electrode 8 corresponding to the display signal voltage to change the array direction of liquid crystal, thereby making a display. Thus, a voltage can be applied between each opposite data bus 2 and the picture element electrode 8 independently by providing the picture element electrode 8 so that the electrode 8 faces and straddles the plural data buses 2. Namely, plural picture elements are driven by one thin film TR. Consequently, the resolution and yield are improved.

Title: Detector for original density
Inventor: MUNAKATA KOICHI
IPC: G03G15/04
Filed: 1985-04-02
Abstract: PURPOSE:To prevent apparently the density of an original from varying by utilizing the extension of the influence of variation in the quantity of light of a light source, the linearity of a photodetecting element, and variation in the drift and gain of an amplifier to an electric signal based upon reference density. CONSTITUTION:A switch 9 supplies an electric signal to a comparator 6 when the original 3 is irradiated by the light source 1. The comparator 6 compares the voltage which is generated through a reference density plate 8 and held in a latch 10 with the electric signal based upon the density of the original 3 and determines the density of the original by their ratio to output a signal regarding the determined density. The reference density plate 8 and original 3 are irradiated in an extremely short time, so the variation in the quantity of light of the light source 1, the variation in linearity for converting the light of the photodetecting element 4 into an electric signal, and the variation in the drift and gain of the amplifier 5 vary both the electric signal output of the density of the reference density plate 8 and the electric signal output of the density of the original 3. Consequently, the reference of the original density also varies and those variation factors are canceled, so that the density of the original 3 does not vary apparently.

Abstract: PURPOSE:To attain a high-speed process at a CPU part, by converting the timing pulse signals synchronized with the shift of a printing head into a count pulse signal, a directional signal and a compensating signal, respectively. CONSTITUTION:Timing signals 4 and 5 are fed to an exclusive OR circuit 19 and then to a D-type flip-flop 21 to obtain a directional signal 7 from the output if the flip-flop 21. On the other hand, the output of an RS flip-flop 17 is fed to a monostable multivibrator 18 to use the edge pulse of the fall of the monostable multivibrator 18 for the timing pulse count signal 6. This signal 6 is supplied to a CPU part 3. IN case the direction is reversed, the count-up of a counter is inhibited since the printing head is at the same position for the pulse point before conversion of the direction and the following pulse point after conversion of the direction. In this connection, the compensation signal 8 is delivered to inform the count decision to the part 3 when the direction is reversed.
