Title: Toner fixation sensor
Inventor: FUKUDA MASUO
IPC: G03G21/00
Filed: 1987-05-25
Abstract: PURPOSE:To contrive to improve the quality of a printed matter by comparing the density difference of a prescribed pattern before and after toner fixation, deciding whether the toner fixation has been ended normally or not, and executing the printing. CONSTITUTION:A prescribed pattern printed at the fixed position of a form 1 developed onto a photosensitive drum 2 is transferred to the form 1, and the density of the prescribed pattern before a toner fixation is measured by a density sensor 3. After a toner on the form 1 has been fixed by a fixing device 4, an unfixed toner of the prescribed pattern is eliminated by an unfixed toner eliminating brush 5, and the density of the prescribed pattern which has been fixed again is measured by a density sensor 6. Density data of the prescribed patterns sent from both the density sensor 3 and the density sensor 6 are compared, and whether the toner fixation has been executed normally or not is decided. In such a way, an unfixation due to contamination of a flash part, etc., can be prevented.

IPC: G03F7/30
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To obtain thick film patterns having high accuracy and high aspect ratio with high productivity even in large-area patterns by imparting a peeling liquid for dissolving or swelling the resin of thick films in regions where resist films do not exist. SOLUTION: A photoresist layer 3 is formed on the surface of the thick film layer 2 formed on a substrate 1. A photomask having translucent patterns of the same shape as the shape of the patterns of desired barrier ribs is arranged on the photoresist 3 surface and the photoresist is subjected to contact exposure. The exposed parts are photocrosslinked and cured and are made insoluble in a developer by the exposure. The unexposed parts are removed by development processing and the resist patterns of the same patterns as the patterns of the barrier ribs are formed. Next, the peeling liquid which has low activity to the resist patterns and dissolves or swells the resin binder of the thick film layer 2 is applied over the entire surface to dissolve or swell the resin of the thick film layer in the regions not coated with the resist.  The remaining resist is thereafter peeled and 15 baked, by which the barrier ribs 2 are formed.

Title: Speed controller for motor
Inventor: KITAYAMA HIROYASU
IPC: H02P7/29
Filed: 1983-07-13
Abstract: PURPOSE:To suppress the switching loss of a power transistor by lowering the carrier frequency of a pulse width modulation proportionally to the increase in the load current of a motor. CONSTITUTION:An error amplifier 21 outputs an error voltage between the speed voltage Vf outputted from a speed detector 17 and the speed command voltage Vs. A comparator 24 compares a triangular carrier signal from a variable frequency oscillator 22 with the error signal and supples a pulse width modulation signal to a power transistor 16. The frequency of the triangular carrier signal from the oscillator 22 decreases when the load current to a DC motor 2 increases. Thus, the switching loss of the power transistor can be suppressed.
