Title: Stylus pressure fluctuation preventing device during jitter compensation of rotary recording medium reproducer
Inventor: INOE MASAYUKI
IPC: G11B3/12
Filed: 1980-08-15
Abstract: PURPOSE: To eliminate the fluctuation of stylus pressure for a rotary recording medium reproducer having a magnet at the rear end of a cantilever plus a jitter compensating coil near the magnet, by setting the direction of force to be applied to the magnet at a larger angle than the axial direction of the cantilever shaft.  
     CONSTITUTION: A permanent magnet 7 magnetized toward the longer side of a cantilever 3 is fixed to the lever 3 with an inclination of angle. The lever 3 is supported by a damper 6. A jitter coil 9 has its axial line equal to the magnetizing direction of the magnet 7. As a result, a line of action 14 of the force (f) that affects the magnet 7 crosses Y axis 13 at angle β. This angle β is set at a prescribed value. As a result, the stylus pressure has virtually no fluctuation although some force is applied to the magnet 7, i.e. the cantilever 3 that compensates the jitter. Thus the stable reproduction is possible.

Title: Electric heater
Inventor: KUBO HIROSUKE
IPC: F24C7/04
Filed: 1994-05-26
Abstract: PURPOSE:To increase a heating effect by providing auxiliary electrodes aside from electrodes at both the ends of a planar heater, changing an electric current feed to the auxiliary electrodes depending on room temperature and changing an applied voltage to the planar heater based on electric current feeding positions. CONSTITUTION:In a 'strong' operation, an electric current is fed to electrodes 4a and 4b at both the ends of a planar heater 4. When room temperature is detected and the 'strong' operation is switched to 'intermediate' and ''weak'' operations by a thermostat or switches or the like, the electric current feed to the electrode 4b at the lower end of the heater 4 and auxiliary electrodes 4c to 4e is sequentially switched while changing applied voltage sequentially from the upper part to the lower part. Accordingly, the heating part of the planar heater 4 sequentially shifts downward from the upper part. For example, in the case of a ceramic planar heater 4, the base material of the heater is conductive and the temperature of a part which is not heated is not extremely lowered due to natural convection heat, since heat is transferred from the heating part and the heating part is located in the lower part. Thus, a heating effect can be increased.
