Title: Magnetic recording and erasure circuit
Inventor: KAWAKAMI KAZUKUNI
IPC: G11B5/024
Filed: 1986-09-24
Abstract: PURPOSE:To erase a signal in a short time by using an erasure signal whose frequency is changed stepwise from the center frequency of a color difference signal to a frequency higher than a recording frequency. CONSTITUTION:In operating an erasure key of an operating section 104, a control circuit 12 outputs a signal 96 to throw an analog switch 52 to the position of a contact (a) and a signal 95 turns off an analog switch 45. Then an erasure signal 90, an output permission signal 91, an erasure drive signal 93 and a control signal 92 are outputted from the circuit 12 to an FM modulator 24. The signal 92 is outputted as a pulse having a pulse width corresponding to two vertical scanning periods 2V and whose center frequency in the color difference signal is nearly 7MHz and outputted then four times during the period of 2V up to the upper limit nearly 20MHz of the recording frequency at an interval of 1V. Thus, an erasure current over 1.2 times the optimum recording current or over is fed to a magnetic head 56 via the modulator 24. Thus, one track is erased by only 11V altogether and the erasure time is reduced.

Title: Cassette loader
Inventor: SHIMIZU TOSHISUKE
IPC: G11B15/675
Filed: 1989-08-31
Abstract: PURPOSE:To attain the simplification of constitution and cost reduction by forming a hole at a holder on which a first or second cassette is selectively placed, closing the hole with a slider and abutting a second reference pin on a slider when the second cassette is placed. CONSTITUTION:When a small cassette C is loaded, no projecting pat 81a of a select lever 81 is pressed, and no slider 82 is turned, therefore, the hole 83 of a C holder 43 is closed. When the holder is loaded, the upper plane of a slider receiving pin 85 is abutted with the lower plane of the slider 82, and the height of the small cassette C is regulated via the slider 82 and the C holder 43. Meanwhile, when a normal cassette S is loaded on the holder, the hole 83 of the C holder 43 is opened, and the slider receiving pin 85 pierces through the hole 83, and the holder is descended lower than a position when the small cassette C is loaded. As a result, the normal cassette S is abutted with an F reference pin 86, then, the height of it is regulated. In such a way, the simplification of the constitution and the cost reduction can be attained.

Title: Vertical magnetic anisotropic film and manufacture thereof
Inventor: KUNIMOTO AKIRA
IPC: H01F10/12
Filed: 1987-09-09
Abstract: PURPOSE:To improve recording-reproducing characteristics and durability by fixing while filling with an organic material gaps of columnar projections wherein a ferromagnetic body is grown over the surface of a base having fine projections of high density, and arranging on the top thereof an abrasion resistant thin film. CONSTITUTION:A vertical magnetic anisotropic film is formed by a base 2 having fine projections 1 of high density; ferromagnetic bodies 3 grown from the projections 1 on the surface of the base 2; an organic material 4 which is fixed by filling gaps between the columnar projections formed by the growing ferromagnetic bodies 3; and an abrasion resistant film 5 arranged on the topmost. The organic material 4 is filled only into the intervals of these projecting particles without increasing the thickness of the top surface of the columnar projections, and the abrasion resistant film 5 is then arranged thereupon. Because the gaps of the projecting particles are filled by penetration especially in a solution state by the organic material, they can be fixed detailedly, and oxidation of magnetic particles is prevented. Furthermore, because it is not necessary to increase film thickness on the top of the projection, not only a large reproduction output can be obtained for the recording-reproducing characteristics but also the S/N ratio is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a checking method for the function of memory elements which indicates the state of a device by bringing a second memory element into a specified first state and estimating the time necessary for this memory to be transferred from the first state to a second state for checking the first memory element. SOLUTION: When a switching means S1 is closed, the first condenser C1 is charged through a resistor R1 and correspondingly it applies to the second condenser C2. The time required for the second condenser C2 to be discharged to the first condenser C1 from a specified charged state is measured. For the measurement, the second port is low-resistance-connected during the first period and the memory element is brought into the first state. During the second period, the port 105 is high-resistance-connected and transferred to its second condition. This measurement is many times repeated, and at this time the charging condition of the first condenser C1 is charged in the period of measurement.

Filed: 1983-11-30
Abstract: PURPOSE:To prevent adhesion of a mist-shaped photo-resist on a wafer by using a double cup and sucking the mist-shaped photo-resist from a clearance between an outer cup and an inner cup. CONSTITUTION:A photo-resist dropped onto a wafer 4 from a nozzle 7 forms a photo-resist layer on the surface of the wafer by centrifugal force. A mist-shaped photo-resist is generated from the dropping of the photo-resist and the photo- resist blown off by centrifugal force at that time. Cups 5, 6 are mounted in order to prevent adhesion on the surface of the wafer of the mist-shaped photo- resist. With the outer cup 5, suction holes 8 are formed to the bottom of a cup base body, and each connected to a vacuum pump. A connecting section 9 with an oblique section is shaped to the outer circumrerence of the cup base body, and photo-resist drops are directed downward. The nose of a horizontal collar section 10 extends up to the outer circumference of the waer 4. A collar section 11 for covering the lower surface of the wafer is formed to the inner circumference of the cup base body.

Title: Sound field correction device
Inventor: KATOU SHINJIROU
IPC: H04S5/00
Filed: 1989-09-01
Abstract: PURPOSE:To prevent interference between a direct sound component and a reflected sound component in an output signal obtained by adding a false reflected sound signal to an input audio signal by making a low band component not to be contained in the false reflected sound signal by using a filter to re move the low band component. CONSTITUTION:The input audio signal is supplied to an adder 14, and simultane ously, it is supplied to an HPF(high pass filter) 15, and the output of the HPF 15 is connected to a reflected sound generation circuit 13. Therefore, the low band component is not contained in the false reflected sound signal outputted from the reflected sound generation circuit 13, and this false reflected sound signal is added to the input audio signal by the adder 14. Accordingly, an audio signal outputted from the adder 14 and given sound field correction contains only a direct sound signal as the low band component. Thus, the change or the flatness of rythm due to the interference between a direct sound and a reflected sound are never caused.

Abstract: PURPOSE:To reduce the jitters of a D-VCO master clock by generating switching control pulses by using a 2nd master clock which is 180 deg. out of phase at the same frequency, and substituting a 1st two master clocks with the 2nd one master clock. CONSTITUTION:When a '0'-phase and a pi-phase master clock generated by an LSI master clock except in a D-PLL circuit are inputted to a toothless clock generating circuit, the former is applied to an N-scale counter 6, a switch 91, and a D-type flip-flop 82 and the latter is applied to the D-FF 81 and switch 91. When the counted value of the N-scale counter is between '0' and '1', two '0'-phase clocks are substituted with one pi-phase master clock. Consequent ly, the frequency of the '0'-phase master clock is f(N-1)/N and T' of an equa tion (T'/T)X360=360 deg. (T': time of movement of leading edge, T: time of one cycle) becomes (1/2)T, so the jitters are at 180 deg. and the D-VCO master clock where the jitters are reduced is supplied to the D-VCO.
