Title: Drop-out protecting circuit
Inventor: SENOO TAKANORI
IPC: G11B20/18
Filed: 1986-06-05
Abstract: PURPOSE:To prevent an off track even when there is eccentricity in a disk by holding correct error signals before occurrence of a drop-out during a drop- out period. CONSTITUTION:When reproduction signals are interrupted by the drop-out, a drop-out detecting circuit detects it and gives a holding command to a holding circuit 3, and at the same time, changes a switch 3 to the holding circuit side. Error signals for controlling a pickup pass through a delay circuit 1 and held by the holding circuit 2. Accordingly, even if the detection of the drop-out detecting circuit is delayed, a correct value before the occurrence of the noise in error signals can be held, and the value is outputted to a servo circuit of a later stage through the switch 3 during the drop-out period. When the drop-out period terminates, the drop-out detecting circuit 4 stops outputting of the drop- out signals. Accordingly, the switch 3 outputs the error signals directly.

Title: Polyvinyl alcohol-based mixed composition
Inventor: OKAZAKI MASAKI
IPC: C08L29/00
Filed: 1978-10-23
Abstract: PURPOSE: To obtain the title composition potentially resistant to bailing water, by adding to a PVA aqueous solution of a specific concentration a particular amount of either ethylene glycol diglycidyl ether or an adduct prepared by adding a 1-halogen- 2,3-epoxypropane to a polyamide-condensed substance.  
     CONSTITUTION: The objective composition can be obtained by incorporating a 5W 70wt% aqueous solution of a polyvinyl alcohol having a polymerization degree of 300W3,000 and a saponification degrees of 80W100mol% with 5W50wt%, based on the wt. of the PVA, of either ethylene glycol diglycidyl ether or an adduct prepared by adding a 1-halogen-2,3-epoxypropane to a polyamide-condensed substance. This composition is stable from room temperature to ca. 130W140°C without any change in the viscosity; however, when converted into a system consisting of the PVA and the ingredient(s) by removing water by means of drying, etc., it will become insoluble to water by heating, and also insoluble to even a 100°C boiling water.

Title: Detecting device for toner residual quantity
Inventor: KANAI HIDEFUMI
IPC: G03G15/09
Filed: 1981-08-19
Abstract: PURPOSE:To detect accurately the quantity of a residual toner on a total quantity basis by providing a detecting conductor in parallel with a developing roll approximately and detecting the quantity of the residual toner by a voltage induced in the detecting conductor. CONSTITUTION:The AC voltage from an AC bias power source ACS is applied to a developing roller 12, and a detecting conductor 15 is arranged so as to face to the developing roller 12, and an induced voltage is generated in the detecting conductor 15. Since a toner 10 contains iron, the magnetic permeability is  changed in accordance with the quantity of the toner 10 between the developing roller 12 and the detecting conductor 15, and the induced voltage generated in the conductor is changed. Thus, the quantity of the residual toner is detected as a total quantity more accurately in comparison with the device which detects at one point whether the toner exists or not.
