Filed: 1989-02-04
Abstract: PURPOSE:To supply feeble current to a heating coil via resistors when a power switch is turned off as well as to make it possible to discriminate current flowing in a macromolecule thermister when current between coils is short circuited by connecting the resistors between the respective contact points of power switches connected with the both ends of a heating wire, and thereby outputting signals from detecting coils. CONSTITUTION:Wiring which monolithically incorporates a heating coil 5, a macromolecule thermister 6 and a detecting coil 7, is disposed to the sensor heating wire 2 of a warming temperature control device 1. The relay contacting points K11 and K12 of a power switch are connected with the both ends of the heating coil 5, and resistors R1 and R2 are concurrently connected with the respective contact points K11 and K12 of the power switch. Feeble current is supplied to the heating coil 5 via the resistors R1 and R2 by outputting signals from a detecting coil 7 when a power switch is turned of, so that current flowing in the macromolecule thermister 6 is thereby discriminated when current between the coils is short circuited.

Title: Deviation detector
Inventor: UECHI MUNETOSHI
IPC: G01B21/22
Filed: 1979-03-07
Abstract: PURPOSE: To detect the possible damage of a coupling unit, by using one of rotary members connected to each other by the coupling unit, as a reference and detecting the deviation of the other rotary member in the rotating direction relative to the former rotary member.  
     CONSTITUTION: Magnetic members 16, 17 are attached to coupling members 13, 14 connected to a shaft 11 on the side of a motor 7 and another shaft 12 on the side of a load. Each of magnetic sensors 3, 4 produces one pulse shifted by a half pulse, depending on the magnetic members 16, 17 when the coupling members 13, 14 perform one rotation without twisting. The pulses A, B produced by the sensors 3, 4 are applied to an OR gate 5, the output pulse (A+B) of which is applied to a preset counter 6. When the output pulse (A+B) has an "H" level, the counter 6 counts continuous pulses C supplied from a pulse generator 8 connected to the motor 7. The width of the pulse (A+B) increases when the coupling members 13, 14 deviate from each other. The deviation can be detected from the number counted by the counter 6.

Title: Automatic tracking apparatus
Inventor: MATSUDA HISANORI
IPC: G01S3/42
Filed: 1979-03-09
Abstract: PURPOSE:To improve the selection accuracy of the target airplane by reducing the received band width during the searching mode and the action of the rate memory. CONSTITUTION:This apparatus is composed of a receiving section 2 which is adapted to separate and combine the bearing and elevation components in the frequency and make them separable with a demodulator 5, a mode indicator 10 for disignating various modes including automatic and manual tracking search modes and the like. In the aforementioned arrangement, when the mode signal from the mode indicator 10 is applied to the gate circuit 11 instead of the use of the video output including search mode and rate mode, the voltage of a frequency indicating voltage generator 9 extends to an intermediate frequency generator 4 to actuate a band varying element narrowing the band range to about one-twentieth of that when the video is generated. This allows the receiving of only the desired frequency provided that the difference between the incoming frequencies is over one-twentieth larger than that in the wide band range. Upon the end of the automatic search mode, the indicator 10 shifts to the automatic tracking mode and the gate circuit 11 is closed thereby making possible the receiving of frequency in the wide band range.

Abstract: PURPOSE: To provide a duplex tray capable of minimizing denting and deletions on a sheet edge. CONSTITUTION: An electrophotographic printer comprises a duplex tray 16 for collecting sheets 56 having an image formed on one side thereof. When an image is formed on one side of the successive sheets 56 collected in the duplex tray 16, the sheets 56 are transported from the tray 16 to a plurality of processing stations of the printer. At least a single backstop member 50 is disposed on the duplex tray 16. The backstop member 50 is engaged with an edge 54 of the collected sheets 56. Further, the backstop member 50 stops the movement of the sheets 56 and is adapted to deflect upon being contacted by the sheet edge 54. When the leading edge 54 of the sheet 56 is engaged with the backstop member 50, the backstop member 50 deflects and absorbs energy.  This arrangement also increases the sheet contact area so as to minimize denting and deletions of an edge of an image on the contacted sheet edge 54.
