Title: Rotary head device
Inventor: SUGIZAKI YASUO
IPC: G11B5/31
Filed: 1991-09-30
Abstract: PURPOSE:To improve precision with respect to the adjustment of parts and reliability with respect to the connection of the parts, and simultaneously, to attain the simplification of the structure and the manufacture of a drum and high density recording in recent years, and in addition, to suppress the damage of a magnetic tape at the time of tape loading. CONSTITUTION:By applying vacuum thin film forming technique to a pedestal 40, magnetic heads 41 are formed, and simultaneously, circuits 42 connected to these magnetic heads are formed. Therefore, since the magnetic heads 41 and the circuits 42 can be formed on the pedestal 40 through one and the same manufacturing process, the mechanical adjustment of the individual head required after the assembling of the drum in the past becomes unnecessary. Besides, since a circuit board, etc., is useless, the number of fitting places and the number of the parts can be reduced, and simultaneously, fitting space can be reduced, and in addition, a coil winding process, etc., becomes useless. Besides, the load of the magnetic tape 32 to be given from the pedestal 40 at the time of the tape loading can be reduced as well by protruding the whole outer periphery of a rotaty pedestal beyond the peripheral surface of the drum.

Abstract: PURPOSE:To selectively etch n-type Si and p-type Si by a method wherein the concentration, the liquid temperature and the agitation speed of an etchant are controlled to specific ranges. CONSTITUTION:A p-type or n-type Si semiconductor substrate 1, a comparison electrode 2 and a counter electrode 3 are connected to a potentiostat 6. An electric current I is controlled in such a way that a potential V of the Si semiconductor substrate 1 with reference to the comparison electrode 2 is set to a desired value. The flow rate of ammonia gas is controlled by using a mass-flow controller 12; and the concentration of ammonia is maintained. An agitator 14 controls a flow speed; and a heater 15 adjusts a temperature. That is to say, the concentration, the liquid temperature and the agitation speed of a basic solution are kept at a condition under which the passivation potential of n-type Si is at the spontaneous open-circuit potential or lower of p-type Si; and only a p-type Si region is etched. The concentration and the liquid temperature are kept at a condition under which the spontaneous open-circuit potential of p-type Si coincides with a passivation potential and the spontaneous open-circuit potential of n-type Si does not coincide with the passivation potential. No bias or a bias voltage at less than the spontaneous open-circuit potential of n-type Si is applied. Thereby, only an n-type Si region is etched.

Title: Picture coding device
Inventor: DATAKE KENJI
IPC: H03M7/30
Filed: 1991-10-02
Abstract: PURPOSE:To visually improve the picture quality of a dynamic picture encoder by providing a means preventing the transfer by masking the high-pass component of the orthogonal conversion when the quantization step width is more than the constant value in the device performing the inter-frame/intra-frame orthogonal conversion coding of a dynamic picture signal. CONSTITUTION:A high-pass mask circuit 16 receives the quantization step width designated by a buffer memory 14. When it is higher than the prescribed value, only the high-pass component is masked by the prescribed mask pattern. Therefore, only the low-pass component is transferred to a quantizer 5 to be quantized, resulting in reducing the information amount stored in the buffer memory 14. When it becomes lower than the prescribed value, the buffer memory 14 designates finer quantization step width to the quantizer 5 and a reverse quantizer 6. Thus, the only low-pass component of the picture is quantized with finer step width by the quantizer 5, permitting a viewer to clearly view the visually important low-pass component.
