Title: Cassette type bubble memory device
Inventor: FUTAMI TOSHIO
IPC: G11C11/14
Filed: 1983-03-04
Abstract: PURPOSE:To reduce the price, and to make the size small and to improve the reliability of a cassette by providing a freely slidable transparent display member in front of the cassette, providing a light emitting element and a photodetector in a cassette adapter and forming a part of face of the photodetector side of a slanted face. CONSTITUTION:When a cassette 10 is inserted into the cassette adapter 20, light emitted from a photodetector 21 is reflected by the slanted face 12a of the display member 12 and arrives at the eye of an operator. At this time, since the light does not arrive at a photodetector 22, the photodetector 22 becomes cut-off state, and information writing function is cut off and information in the cassette is protected. When the display member 12 is slid in the direction of arrow A, a plane part 12b is positioned between the light emitting element 21 and the photodetector 22. Light from the light emitting element 21 is directly transmitted to the photodetector 22 through a light path C. The photodetector 22 attains to conducting state, and information writing function operates.

Title: Metal discriminating device
Inventor: IWANAGA KENJI
IPC: G07D5/08
Filed: 1980-03-18
Abstract: PURPOSE:To discriminate whether the metal to be discriminated is a prescribed metal or not, by composing the amplitude difference and the phase difference of a detection signal generated in a detection coil and by setting an output signal level so as to be the minimum when the metal to be discriminated is the prescribed metal. CONSTITUTION:The alternating magnetic field is applied to metal X to be discriminated by exciting coil 10 to which the output of oscillator 9 is applied, and the detection signal of detection coil 11 which is arranged oppositely to coil 10 through metal X is applied to correcting circuit 12 together with the output of oscillator 9. Correcting circuit 12 sets the level so that detection signal A of detection coil 11 and the output of oscillator 9 have the same amplitude level when a perscribed metal is inserted as metal X between both coils, and their phases are shifted to those opposite to each other by the phase shifter so that the addition output of operational amplifier 13 becomes zero approximately. In case of the metal other than the prescribed metal, this output does not zero, and the output is obtained from level deciding circuit 14. As a result, metals having characteristics which are much alike are discriminated from each other, and the influence of temperature fluctuation and power source voltage fluctuation is eliminated.

Abstract: PURPOSE: To enhance utilization of heat by installing a shielding plate curved in the direction of the burner between a heating drum and a heat retaining stirring chamber used for heating and regeneration of waste asphalt generated by road repairing.  
     CONSTITUTION: When a drum is rotated and, at the same time, a burner 6 is ignited, waste asphalt put in from a hopper 5 is heated by both direct heat of fire and radiant heat caused by a shielding plate 13.
