IPC: F02B1/04
Filed: 1989-07-21
Abstract: PURPOSE: To more reduce heating time compared with a prior art glow plug of a sheathed element and hence prolong sufficient effective life of a glow plug, by making larger a resistance ratio of a material of an adjusting filament than about 7.5 in a temperature ratio of 20 deg.C/1000 deg.C. CONSTITUTION: In a glow plug device 1 a heating filament 2 is connected with an adjusting filament 3 through ordinary welding. Both shortening of heating time and prolong of effective life capable of actually operating are achieved by employing for the adjusting filament 3 a material where a resistance ratio is made larger than about 7.5, e.g. 14 in a temperature ratio of 20 deg.C/1000 deg.C. As a proper material, there is known nickel/iron and cobalt/iron for example, particularly cobalt/iron. For an adequate material as the adjusting filament having electric resistance of a positive high temperature coefficient there is known a nonlinear alloy where a ratio of resistance at higher temperature than 750 deg.C and resistance at room temperature is larger, and the resistance is first flat and rapidly larger as temperature rises.

Title: Developing cartridge for electrophotographic printer
Inventor: SHIMODA TAKENOBU
IPC: G03G15/08
Filed: 1989-07-24
Abstract: PURPOSE:To detect the service life of a developing cartridge from the recovery amount of waste toner by transmitting the torque of a full-base disk to a full disk via a spring and operating a switch via grooves provided on the peripheries of both disks. CONSTITUTION:Waste toner 2 on a photosensitive drum 1 is scraped away by a cleaner part 3, and fed to a containing part 5b in a toner recovery vessel 5 by the turn of a carry-in vane 4. Namely, when the full-base disk 8 is driven and rotated, the full disk 6 rotates via the spring 7, which leads the carry-in vane 4 to rotate. In this state, the grooves 6b and 8b of both disks 6 and 8 do not coincide with each other. When the recovery vessel 5 is full of the toner 2, the resistance of the carry-in vane 4 increases to raise the torque of a rotary shaft 13, and accordingly the spring 7 stretches to allow the phases of the grooves 6b and 8b of the disks 6 and 8 to be coincident with each other. An actuator enters the befitting grooves, and a microswitch 10 is operated while interlocking the entering. Consequently, the service life of the developing cartridge is detected.

IPC: H04N5/66
Filed: 1985-08-30
Abstract: PURPOSE:To obtain a small-sized clamping circuit of high utility by applying the output of a smoothing circuit to a DC stopping capacitor by a pedestal level clamping switch which is switched with a clamp pulse to adjust the pedestal level. CONSTITUTION:In case of underflow, that is, if a low luminance signal level corresponding to a dark part of a display picture does not exceed the threshold of a comparator of the least significant digit of an A/D converter 115, the first gate 104 closes the first switch to connect the smoothing circuit to VDD. In case of over flow, that is, if a luminance signal level corresponding to a light part exceeds the threshold of the most significant digit of the A/D converter 115, the second gate 105 closes the second switch 109 to connect the smoothing circuit to VSS. Thus, the output voltage of the smoothing circuit is raised for the dark picture and the DC bias of a composite video signal is raised to make the display picture lighter, and the DC bias is reduced for the light picture to make the display picture darker.

Title: Flat motor
Inventor: TANAKA KEIICHI
IPC: H02K41/025
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a flat motor that can move two-dimensionally on a flat plane that has a light-weight moving member which can move rapidly. SOLUTION: When current Ia flows in an armature coil 10a of a stator- exciting section 4a, magnetic flux ϕ1 is generated in accordance with the right- handed screw rule. The magnetic flux ϕ1 then causes eddy current Ie in a frame-like section of a conductive member of a movable member unit 16. By causing current 1b to flow in an armature coil 10b of the stator exciting section 4b as shown in the figure and thereby causing current Ic to flow in an armature coil 10c of the stator exciting section 4c in the direction opposite to that of the current Ib, a magnetic flux loop of magnetic flux ϕ2 is formed.  Since the magnetic flux ϕ2 crosses at right angles to the direction of the eddy current Ie in the conductive member 6, force F is generated by Fleming's left-hand rule and that force works as W thrust for moving the movable member unit 16 in the relatively direction against a stator exciting unit 1.
