Title: Optical pickup device
Inventor: NAKAMURA TOSHIO
IPC: G11B7/09
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To avoid the deformation and breakage of a supporting frame. SOLUTION: An optical pickup device is composed of a movable part which has an object lens 17 and a fixed part which supports the movable part elastically. In order to support the movable part and the fixed part at upper and lower end parts and left and right end parts by an elastic supporting frame, the movable part and the fixed part are linked with a reinforcing rectangular frame with linking pieces 36-39 (36'-39') therebetween. The linking pieces of the elastic supporting frame which are attached to the upper side of the movable part and the linking pieces of the elastic supporting frame which are attached to the lower side of the movable part are cut at different positions. If the upper cut positions are different from the lower cut positions, the cut end surface of the linking piece is not brought into contact with a cutting blade by the vertical stroke of the cutting blade.  As a result, even if the supporting frame connected to the linking pieces is very slender and thin, an excessive stress is not applied to the supporting frame and the breakage of the frame can be avoided.

Title: Heater turn-on controller
Inventor: KATOU EIICHI
IPC: G05D23/19
Filed: 1984-03-14
Abstract: PURPOSE:To prevent the faulty turn-on of a heater due to CPU runaway by integrating the output of an output port which drives a heater and supplying this integrated value to an input of an A/D converter of a CPU. CONSTITUTION:A temperature detecting thermistor 1 set close to a fixing roll 6 of a copying machine is connected to a CPU2, and the input data is compared with the value corresponding to a prescribed roll temperature programmed previously. A heater 4 of the roll 6 is driven at an output port P1 of the CPU2. The signal sent from the port P1 is integrated (R2, C1) and then compared with the threshold values set by two comparators CMP1 and CMP2. An SSR3 is turned on within said threshold value to conduct a heater 4. Thus the port P1 is latched at H(L) in case the CPU2 has a fault such as a runaway, etc. owing to the external noises, etc. Therefore no output is delivered from both comparators and the SSR3 is turned off.
