Title: Driving mechanism of tape recorder
Inventor: KURAFUJI TAKAMASA
IPC: G11B15/02
Filed: 1979-03-16
Abstract: PURPOSE: To reduce the flutter as soon as possible by setting the rotational frequencies of various types of rotors which are driven in the reproduction mode less than the flywheel's rotational frequency of the flywheel driving system which is made independent from the take-up driving system.  
     CONSTITUTION: The rotational frequencies of various types of rotors which are driven in the reproduction mode are set less than the flywheel's rotational frequency of the system which drives flywheel 34 of the different system from that which drives take-up reel stage 262. Then the flywheel's rotational frequency is set maximum, and at the same time the rotors of various types which are driven in the reproduction mode are set to less rotational frequencies than the flywheel's rotational frequency. As a result, the flutter component can be reduced effectively.

IPC: B23Q3/06
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To strongly fix a tubular material with excellent stability and without generating a clamp flaw on a recessed receiving surface by coating the receiving surface of a clamp pedestal formed of a hard material with a replaceable soft material clamp receiving surface member. SOLUTION: A clamp pedestal 21 is made of a hard material. A recessed receiving surface of the pedestal 21 is coated with a clamp receiving surface member 22 made of a replaceable soft material. As this receiving surface member 22, the one is a synthetic resin film with one side surface applied with adhesive and the other is a synthetic resin molded product having a shape fittable into a recessed receiving surface of a clamp receiving base.  Because the recessed receiving surface of the clamp receiving base is formed of a soft material, a clamp damage is not generated because aluminum agglutination is buried within a receiving surface member 22 made of a soft material, even if small quantity of aluminum agglutination exists on the recessed receiving surface when a grain size of aluminum agglutination is small, but when the grain size is increased to a certain degree, there is a possibility of generation of a clamp damage. Therefore, this clamp receiving surface member 22 is replaced and generation of the clamp damage is prevented.

Filed: 1981-03-04
Abstract: PURPOSE:To facilitate and secure flash photography by exercising accurate aperture control by simple constitution by automatically controlling an aperture to an adequate value on the basis of the quantity of flash light and object distance. CONSTITUTION:According to the set quantity of light emitted by an electronic flash and the set guide number of a film, a variable resistance VR1 varies in resistance value, and focusing by operating a focusing ring varies the resistance  value of a variable feedback resistance CR2 according to object distance, so  that the output of an operational amplifier OP1 has a value which corresponds  to an adequate aperture value based upon the quantity of emitted light and object distance. When this value coincides with an aperture value outputted by an  operational amplifier OP2 according to variation in the resistance value of a  variable resistance VR3 by driving an aperture in response to the releasing of a  shutter, a transistor Q1 turns on through a comparator CP1 and a magnet Mg1  is energized to stop stop-down operation. Thus, automatic aperture control is exercised by the simple constitution to perform flash photography easily and  securely.
