Title: Camera integrated magnetic recording/reproducing device
Inventor: YOKOYAMA SUKEYUKI
IPC: H04N5/225
Filed: 1988-09-29
Abstract: PURPOSE:To reduce the fatigue of an ear at the time of photographing for a long period by impressing the output of a microphone through a low pass filter, which attenuates frequencies at >= a value obtained with dividing the propagating speed of a voice by the shortest spatial distance between the microphone and a speaker. CONSTITUTION:Instead of a phase variable circuit in a usual constitution, a low pass filter 5, which attenuates the frequencies at >= the minimum resonant frequencies f0 calculated by the shortest spatial distance l between a microphone 1 and a speaker 4, is inserted. Consequently, since a resonant phenomenon is generated in the zero condition of a speaker output and a microphone input, a hawling phenomenon is generated by the amplification of the minimum resonant frequencies f0, and the voice input level to the speaker 4 can be reduced by the low pass filter 5, which attenuates the frequencies at >= the minimum resonant frequencies. Thus, the generation of the hawling is prevented, and the fatigue of the ear at the time of photographing for a long period can be reduced.

Title: Recording equalizer and magnetic recording device using the equalizer
Inventor: MARUYAMA YOJI
IPC: H04B3/06
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To conduct a highly reliable and high density recording by compensating for a portion of the phase of output signals and advancing to the direction corresponding to the distance in which a magnetic head moves against a magnetic recording medium. SOLUTION: Recording data enter into a modulator 7 and process original data under a certain rule so as not to generate a number of 'O's that does not exceed a prescribed number. Then, the output is transmitted to a precoder 8 and is processed to generate the code which has a strong characteristic against the interference among adjacent signals. A shift amount Δ, that represents the difference between a writing clock and the timing in which an actual writing operation is executed, is computed by a recording equalizer 1 and is written into a recording medium by a magnetic head 9. The electric signals read by the head 9 during a reading are amplified by a preamplifier 10 and operated to a certain timing by a PR equalizing circuit 11 and an ML decoding circuit 12.  Then, a portion of the phase of the output signals is compensated for and advanced to the direction corresponding to the distance in which the head 9 moves against the medium.

Abstract: PROBLEM TO BE SOLVED: To improve assembling efficiency and to reduce the number of part items so as to increase rigidity by inserting a ceiling part into each of left and right side plates when the ceiling part is fixed to the left and right side plates by the fitting structure of ceiling irregular parts provided in both left and right ends of the ceiling part. SOLUTION: Recessed parts 2a to be fitted in the upper parts 3a and 4a of left and right side plates 3 and 4 are provided in both left and right ends of a ceiling part 2 in a deep side direction. The center upper parts of the left and right side plates 3 and 5 are formed to be irregular so as to provide space in the vertical direction of a car 1 and cross the uneven parts of a horizontal direction provided in the center parts of the side plates 3 and 4. Thus, since the ceiling part 2 is moved left and right during assembling of the car 1 and the necessity of adjustment for fixing in the left and right side plats 3 and 4 is eliminated, assembling is facilitated and the recessed and projecting parts of the vertical and horizontal direction cross each other. Accordingly, the rigidity of the car is far larger compared with flat plate one.

Abstract: PROBLEM TO BE SOLVED: To enhance the current drive capacity furthermore by increasing the field strength in pinch-off. SOLUTION: P type impurities are implanted into a substrate 2 such that the part close to the surface of a substrate is doped heavily. A polysilicon 45 is then deposited and a resist 52 is formed thereon before implanting N type impurity ions at such extent as causing no inversion from P type to N type (counter implantation). Subsequently, an interlayer insulation film 6 is formed followed by deposition of a polysilicon layer 47. The resist is then patterned to form a control gate and a floating gate. Consequently, the region beneath the floating gate is doped heavily and the region beneath the control gate is doped lightly.

Title: Structure of stator core for capacitor-excited generator
Inventor: SAKURABA KAZUYUKI
IPC: H02K1/20
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To approximate the exterior shape of the entire stator core to a circle and make a magnetic reluctance small by stacking a plurality of core plate aggregates, each of which is made by stacking a plurality of core plates or stacking a plurality of core plates, with cutouts being shiftd in the circumferential direction. SOLUTION: Each of core plates 37 which constitute a stator core has, on its periphery, a pair of cutouts 39 formed, when punched from a steel plate to save material. A plurality of the core plates 37 are stacked with the cutouts 39 being aligned to form a plurality of core plate aggregates 40. The core plate aggregates 40 are stacked with the cutouts 39, being shifted in the circumferental direction to form a stator core. By this method, the shape of the entire stator core can be approximated to a circle, while a magnetic reluctance is lessened and therefore the number of turns of a main coil can be made small, the rate of change in voltage can be reduced, and a large output voltage can be obtained.
