Title: Magnetic head
Inventor: OBATA AKIHISA
IPC: G11B5/235
Filed: 1992-02-25
Abstract: PURPOSE:To provide a magnetic head without degradation of characteristics at a boundary between glass of a composite type magnetic head and a magnetic metallic film and excellent in slidability. CONSTITUTION:A film of SiO2 is formed as a reaction preventing layer 7 between magnetic core main parts 1a, 1b in the magnetic core and a Fe soft magnetic film 2. Also a film of SiO2 as a reaction preventing layer 3 in order to prevent the reaction between a glass 6 and the Fe soft magnetic film 2 at the time of glass bonding, is formed in 2000Angstrom  thickness and a film of CoNbZr as a reaction preventing layer 4 is formed in 5000Angstrom  thickness and besides a film of Cr formed in 1000Angstrom  thickness as a reaction preventing layer 5 is joined with the glass 6. Thus in the magnetic head which used a relatively thicker Co noncrystal alloy film at the boundary, the reaction between the glass and the Fe soft magnetic film is prevented and the slidability of the head is improved.

Title: Oscillatory frequency detecting circuit
Inventor: FUJINO MASAHARU
IPC: H03B1/00
Filed: 1978-03-31
Abstract: PURPOSE: To make it possible to detect and measure the oscillatory frequency in high accuracy without any addition to an aocillatory circuit by varying a main voltage or consumption current.  
     CONSTITUTION: A current-voltage converting circuit or voltage variation detecting circuit 8 interposed between an oscillatory circuit 6 and a power source 7 detects the variation in the consumption curent of the circuit 6 or the voltage of the power source. This current or voltage is varied in synchronism with the oscillatory frequency while containing the oscillatory frequency as ripple. Since the output of the circuit 8 contains the oscillatory freuency component of the circuit 6, its frequency can be measured as the input to a counter 11 by means of a BPF 9 and a waveform shaping circuit 10. Thanks to the detection of the oscillatory frequency, the oscillatory frequency of the circuit 6 can be stably detected without any change in the load upon the circuit 6 and without any provision of the detecting output.

Abstract: PURPOSE:To prevent wasteful consumption of copying paper and to improve operability at the time of exchanging a developing device by detecting the mounting condition of the developing device and stopping an image forming operation. CONSTITUTION:The developing device 5 in which a color toner is loaded is freely attachably and detachably constructed. The developing device 6 into which a black toner is loaded is fixed.
