Title: Sound recording and reproducing device for magnetic disk
Inventor: OOTA YOSHITAKA
IPC: G11B20/02
Filed: 1986-06-10
Abstract: PURPOSE:To attain the easeiness of hearing of a sound signal while the recording and reproducing time of the sound signal is prolonged by providing a means applying compression for a time thinning the sound signal and a means expanding the thinned sound signal for an interpolated time. CONSTITUTION:In storing a digital signal being the result of conversion of a sound signal by an A/D converter 1 into a memory 2, the gate control is applied to gate circuits 21, 22 to thin and store a part of the digital signal periodically. Thus, even with the time compression and time expansion the same as the conventional system, the sound recording time is prolonged depending on the ratio of period To to Ti without changing each characteristic. Further, the sound output being the result of reproduction applying expansion to the sound subjected to compression recording is quickened by the thinned signal, but since the amplitude of the sound is unchanged, no difficulty of hearing is caused.

Abstract: PURPOSE:To realize an electrode wiring having no disconnection by forming an anode electrode wiring on a monolithic LED array P-type GaP epitaxial layer through deposition of titanium between silicon dioxide and gold. CONSTITUTION:In order to form a PN junction in a semi-insulating GaP substrate 1, a P-type epitaxial layer 3 is partially lapped over an n-type epitaxial layer 2 and melted back and a cathode electrode wiring 5 is formed of Au-2% Si while passing over the n-type layer 2 thus forming a silicon dioxide film 4 having electrode take-out windows on the P-type layer 3 and at each electrode end. Au-5%Zn is then deposited on the P-type layer 3 and at each electrode end and resist is applied on the silicon dioxide film 4 which is subsequently exposed and developed using a mask passing the Au-5%Zn deposited on the P-type layer 3. Titanium is then deposited on a line thus formed passing the Au-5%Zn followed by deposition of gold thus obtaining an anode electrode wiring having no disconnection.

Abstract: PURPOSE:To reduce an error in the adjustment of a white balance with simple circuit constitution and to improve a color reproduction by suitably moving a white balance adjusting central color temperature in a white balance adjusting device controlling the gain of a chromaticity signal in accordance with the level of color temperature of an object to be photographed. CONSTITUTION:The present device is constituted so as to control the reference voltages of automatic white balance circuits 8, 9 by subordinate automatic white balance circuits 6, 7. If the largeness of color difference signals (R-YL) and (B-YL) inputted to the subordinate automatic white balance circuits 6, 7 in which the reference voltage is fixed is changed, the output value of the subordinate automatic white balance circuits 6, 7 namely the reference voltage of the automatic white balance circuits 8, and 9 is changed. Accordingly, the input and output characteristics of the automatic white balance circuits 8 and 9 are shift rightward and leftward corresponding to the largeness of the input color difference signal. As a result, a control characteristic extended in a horizontal axial direction, namely the characteristic of an improved white balance characteristic can be realized.

Filed: 1994-06-16
Abstract: PURPOSE:To prevent temperature rise of a voice coil by providing with an air path connected to a magnetic gap and an air path connecting the gap to the outside at the back side of a back plate part. CONSTITUTION:An electric signal is supplied to a voice coil 5. The voice coil 5 generates the drive power in back and forth direction by the magnetic flux in a magnetic gap 11.

The air pressure fluctuation is sent through a groove part 12 being the 1st air path in a hollow part 14. The air in the part 14 passes through each communication hole 13 being the 2nd air path to the outside at the back of a back plate 2. Thus, the voice coil 5 is cooled down by passing the air in the hollow part 14 to the outside in the speaker.

Filed: 1978-10-31
Abstract: PURPOSE: To make an upbeat or downbeat sound of width appropriate to a metronome, by controlling the width through an AND gate which is opened by a shaped tempo signal.  
     CONSTITUTION: Tempo signals from a tempo signal generation circuit 1 are counted by a BCD counter 2, which is reset depending on a number of beats optionally set by a beat setting circuit 3. The reset output of the counter is used as an upbeat and downbeat control signal to switch a gate of an upbeat and downbeat sound generation circuit 4 to apply an upbeat or downbeat sound wave signal from the circuit 4 to a sound width contol circuit 6. An AND gate of the circuit 6 is opened by a tempo signal shaped by a shaping circuit 7 so that the circuit 6 generates an upbeat or downbeat sound signal of width appropriate to a metronome. This results in controlling the width of upbeat or downbeat sound made by a loudspeaker 9.

Abstract: PURPOSE:To make stud welding at stable uniform strength even when a welded base metal is tilted or the weld zone is lower face when a stud is welded to a metallic material made of magnetic body by welding impressing a magnetic field in the set place of welding or using a welding gun having a magnet at the muzzle. CONSTITUTION:A permanent magnet 20 is attached by attraction around the stud welding place of a magnetic base metal 30 such as an iron plate etc. or a welding gun in which an electromagnet is attached to the barrel 6 is used. The muzzle 7 of the welding gun 1 is thrusted against the set place of welding in the magnet 20, and current is applied between the base metal 30, and contact of the base metal 30 and stud 10 is molten by heat of generated arc. Then, current is cut off, and the stud 10 is pulled up slightly, and driven in the molten part of the base metal strongly. Molten parts of the base metal and stud are combined into one, and excess molten materila rise up around the stud. Even when the base metal is tilted, and when he stud is struck from below, the excess molten material is attracted on the face of base metal and does not flow out or fall down from the face of the base metal. Thus, the stud 10 can be welded strongly to the base metal.

Abstract: PURPOSE:To reduce the rolling load, and to make the high draft rolling work possible, by shifting the center of the inner work roll in the direction opposite to the tension acting on the material under-going the rolling pass, and by providing the cavity in the outer work roll. CONSTITUTION:The center A of the inner work roll 6 is shifted toward the run-out side in respect of the center line of the outer work rolls 8, 9, and the center B of the inner work roll 7 is shifted toward the feed-in side. Hereby, the centers A, B, of the inner work rolls 6, 7, are shifted in the direction opposite to the tensions T1, T2, acting on the material S. During the material S is rolled by the rolls, the feed-in side inner work roll 6 is attracted toward the feed-in side because of above stated offset of the roll center, and the run-out side inner work roll 7 is attracted toward the run-out side, and also, the outer work rolls 8, 9, are horizontally held through the material S; hereby, the roll does not cause the horizontal distortion during the rolling work. Further, in some cases, the deformation of the roll is prevented by supplying the electric current to the heater installed in the cavity 11 of the outer work rolls 8, 9.
