Title: Magnetic head device
Inventor: ARIGA MUTSUMI
IPC: G11B5/09
Filed: 1987-08-19
Abstract: PURPOSE:To easily execute auto-tracking while providing the titled device with a reading/writing function by allowing the functions of two gap parts to be switched and arranging two head elements so as to shift them in a track width direction. CONSTITUTION:Two head gap parts Ga, Gb are arranged so as to be shifted in the track width direction of the tape. When the direction shown by an arrow is the forward direction of the tape, the gap parts Ga, Gb correspond to a write gap and a read gap respectively. Consequently, read-after-write can be attained. When the output levels of the gap parts Ga, Gb are compared with each other and the positions of the magnetic heads Ha, Hb are adjusted so that both the output levels are equal to each other, reproducing having no off-track can be attained. In addition, narrow-width recording/wide-width reproducing or wide-width recording/narrow-width reproducing can be attained.

Title: Output buffer circuit
Inventor: SATOU MAKI
IPC: H03K19/003
Filed: 1982-11-26
Abstract: PURPOSE:To prevent the occurrence of offset and error in an output signal, by connecting three MOSFETs in series between a driving power supply terminal and the earth and setting respective base voltages to prescribed values which are increased in order from the earth side. CONSTITUTION:An output buffer circuit 20 is provided with three MOSFETs 22, 23, and 24 connected in series between a driving power supply terminal 21 and the earth. The output of a charge transfer device such as CCD is applied to the base of the FET24, and the output signal is obtained from the source of the FET24. Respective gate voltages VG1, VG2, and VG3 of FETs 22, 23, and 24 are set to prescribed values increased in order from the earth side. As the result, voltages between brains and gates of FETs 22, 23, and 24 are reduced to prevent the diffusion of electrons due to ionization by collision, and therefore, the occurrence of offset, error, or the like in the output signal is reduced.

Abstract: PROBLEM TO BE SOLVED: To perform a welding having excellent beautiful appearance and sufficient strength with a low cost equipment by forming a slit having depth in the front and rear surfaces on a welding line in at least the second plate material so as to remain bridge parts in both end parts thereof and applying the non-consumable electrode arc welding along the welding line from the upper part of the second plate material. SOLUTION: In the second plate material 2, the slit 3 penetrated to the front and the rear surfaces is pre-formed. The slit 3 is not arranged to the whole length in the welding line 4, but plural lines are intermittently formed in series in the welding line 4, and non-cutting state bridge parts 5 are formed at both end parts of the slit 3. Under the condition of piling the second plate material 2 on the first plate material 1, a welding torch 6 of the non-consumable electrode arc welding is directed on the welding line 4 and also, positioned at the one end part of the welding line 4, and while executing the arc welding from this position, the welding torch 6 is shifted along the welding line 4 and executes the welding to the other end part of the welding line 4. That is, the bridge part 5 and the slits 3 are continuously welded.

IPC: G11B33/14
Filed: 1990-08-03
Abstract: PURPOSE:To prevent the carrying of dust or the like into a disk drive by stopping the rotation of a cooling fan when a shutter is opened. CONSTITUTION:Even when a driving power supply for the disk drive is ON, the cooling fan 11 is not still rotated, and after completing the loading of a cartridge C by a control means, the cooling fan 11 starts to rotate simultaneously with the start of a spindle motor.

Title: Method and apparatus for producing magnetic recording medium
Inventor: TSUBOI NOBUO
IPC: G11B5/845
Filed: 1986-09-02
Abstract: PURPOSE:To permit satisfactory non-orientation with good reliability or controllability by disposing plural pieces of magnetic field forming elements contiguously to each other and forming the magnetic fields between the elements as well in three directions within the respective elements. CONSTITUTION:A base is moved along the plural magnetic field forming element disposed nearly contiguously to each other and the non-orientation is executed by forming the different magnetic fields facing at least there directions to each of the plural elements 11 and forming the magnetic fields between the elements 11 as well at this time. The term 'nearly contiguously' includes not only the case in which the elements 11 are in full contact with each other but also the case in which the elements are disposed opposite to each other at the specified spacing between the elements. The non-orientation is thereby uniformly attained with good reproducibility (reliability). In addition, the control of the degree and pattern of the non-orientation is possible by the disposition of the magnet elements 11.

Title: On-vehicle reproducing device
Inventor: SHIMIZU YOSHIO
IPC: B60R11/02
Filed: 1989-08-11
Abstract: PURPOSE:To locate sound in the middle in a front direction by outputting a sound retarded from a rear speaker by a difference signal between L and R and reproducing a monaural signal such as speech by an actor or a vocal especially from the front center. CONSTITUTION:The sum of electric signals L, R from a front central speaker 8C is formed at an L+R circuit of a synthesis section 2 and reproduced through a power amplifier 7L+R as a monaural signal of L+R. Since the monaural signal is the same in L and R, signals of L, R are cancelled by an L-R circuit of a comparison section 3, then no sound is reproduced from rear speakers 9L, 9R. In this case, the L and R signals are synthesized by the L+R circuit of the synthesis section 2 in the front center and reproduced from the front center speaker 8C. Thus, the sound located in the front center is obtained.

Abstract: PURPOSE:To improve the yield and reliability of semiconductor pellet by a method wherein a semiconductor pellet mounted on molten solder is lifted up to the even level of solder thickness by the action of external magnetic field to be cooled down as it is. CONSTITUTION:When a semiconductor pellet 2 containing magnetic metal in the backside electrode layer 2' thereof comes below a magnet 4 as if it is mounted on a molten solder 3, the pellet 2 is supplied with the magnetic field H generated by a magnet 4. The power of the supplied magnetic field H is sufficient to attract the magnet layer 2' of the semiconductor pellet 2 and lift the pellet 2 a bit not to separate it from the molten solder 3'. At this time, even if the semiconductor pellet 2 is tilted a little, any creeping molten solder 3' lifted by the magnetic field H is absorbed underneath the lifted semiconductor pellet 2 to make the solder thickness below the semiconductor pellet 2 even. When the entire semiconductor pellet 2 is cooled down to solidify the solder 3, the pellet 2 may be fixed in parallel with a metallic substrate 1.

Filed: 1992-08-04
Abstract: PURPOSE:To remove noise in the case of superimposing fine noise by outputting any specified value from an adder corresponding to the absolute value of difference between median and (N+1)th signal levels. CONSTITUTION:The f-fold average value of the signal level of an input signal is outputted from a low-pass filter part 31, the median g-fold signal level is outputted from a median filter part 32, and the h-fold (N+1)th signal level is outputted from a signal processing part 33. An adder 34 adds these outputs. The adder 34 is set so as to output a smoothed value when the absolute value of difference between median and (N+1)th signal levels is smaller than a prescribed first level and so as to output median when it is larger than a second level. Thus, this device is operated as the low-pass filter to the fine noise of a small amplitude and operated as the median filter to the pulse signal of a large amplitude. Thus, noise can be removed even to a signal superimposed the fine noise of which level is periodically changed.
