Filed: 1987-12-28
Abstract: PURPOSE:To prevent miserasure of a sound signal by receiving erasing instruction while the sound signal is reproduced as an audible sound by a reproducing means, and erasing the sound signal according to the received erasing instruction. CONSTITUTION:The title device is constituted so that when the erasing instruction is given during the reproduction of a sound, a control code recorded together with the reproduced sound is read, and the erasure of whole one sequence or a part of a sequence is selected and performed. Accordingly, a user is released from such a burden that the reproduces one sequence of the sound extending over plural tracks once briefly, and moves a head to an optional position he wants to erase, and erases the track one by one by a manual operation. Thus, since the erasing instruction is given at the point of time that the confirmation of the erasure of the sound during being reproduced is obtained, miserasure is never caused, and operability is improved.

Title: Transmission system for television signal
Inventor: SUGIMORI YOSHIO
IPC: H04N9/77
Filed: 1987-12-31
Abstract: PURPOSE:To prevent occurrence of rining without losing resolution by processing a transmission signal at the transmission system. CONSTITUTION:A discrimination circuit 4 always checks especially a luminance signal in a video signal picked up by an image pickup device. Since the discrimination circuit 4 checks whether or not a signal remarkable with occurrence of ringing exists, no output signal exists if it does not exist and a changeover switch 5 is thrown to the position shown in figure. The video signal is retarded by a delay circuit 2 by a discrimination time of the discrimination circuit 4 and sent to a processing unit 6. If any signal exists, an output signal of the discrimination circuit 4 changes over the changeover switch 5 to the position opposite to shown in figure. Thus, even when the circuit 3 causing the band limit characteristic is inserted in the transmission system and ringing takes place, it is not remarkable.

SOLUTION: A rod of an air cylinder 16 is contracted to move up a stopper support member 17 so as to protrude stoppers 18, 18a,... from the upper face of a table 3. A laminated body W on the table 3 is delivered so as to come in contact with the stoppers 18, 18a,..., and the tip face of the laminated body W is pressed to the stoppers 18, 18a,.... At this time, compressive force F is acting upon the laminated body W in a lengthwise direction. In this state, a cutter 9 of a cutting part 4 is moved down by air cylinders 8, 8a to cut the laminated body W, but at this time, the stoppers 18, 18a,... bend by about the wall thickness (t) of the cutter 9. The laminated body W therefore escapes by about the wall thickness of the cutter 9 so as to relax compressive force F acting upon the cutter 9.

Title: Optical element driving device
Inventor: NAKAMURA TSUTOMU
IPC: G02B7/00
Filed: 1993-12-28
Abstract: PURPOSE:To obtain a device which can reduce a resistance force to the motive force of the optical element driving device by making the center of the generated motive force shift from an optical axis to a guide member. CONSTITUTION:A magnet 16 which is arranged horizontally is fitted a little to the right of the optical axis O and a magnet 16 which is arranged vertically is fitted a little below the optical axis O. The point P1 on which the thrust force F the resultant force of driving forces operating on a CCD holder 14 operates is arranged is almost on a diagonal Lc since the magnet 16 is arranged shifting from the optical axis O downward to the right and symmetrically about the diagonal Lc. Consequently, rotary moment which operates on a shaft hole 14g as the fulcrum of the CCD holder 14 becomes smaller, a 'twist' phenomenon generated between a guide shaft 8 and the shaft hole of a holder 14 is hardly caused, and smooth retraction driving is enabled with the small motive force.

Title: Manufacture of semiconductor laser device
Inventor: ARIMOTO SATOSHI
IPC: H01S3/02
Filed: 1989-12-25
Abstract: PURPOSE:To avoid formation of a transformed layer and impression of a stress on a semiconductor layer by utilizing the specificity of crystal growth in which crystal growth proceeds independently on the side of a reverse mesa stripe and in the upper part thereof and also by using a selective etching technique for the semiconductor layer. CONSTITUTION:Semiconductor layers 2 to 5 and 10 are made to grow epitaxially on the (001) surface of an n-GaAs substrate 1 respectively. After patterning with a photoresist 11, subsequently, a reverse mesa stripe 7a is formed in the direction <011> by using an appropriate etching liquid. After removal of the photoresist 11, an n-GaAs layer 8a and an n-AlxGa1-xAs layer 12a are made to grow epitaxially by an MOSVD organic metal vapor growth method. When these layers are etched by a selective etching liquid which can etch only GaAs and does not etch A GaAs, only an n-GaAs layer 8b is etched and a shape of a buried ridge can be obtained. According to this method, a burying growth can be made without using a mask for a selective growth, and formation of a transformed layer in a semiconductor layer and impression of a stress thereon are avoided.
