Title: Converter
Inventor: KIJIMA SEIICHI
IPC: H02M3/335
Filed: 1991-03-19
Abstract: PURPOSE:To reduce insulating withstand voltage by half to be small-sized by providing a boosting transformer with the first and second secondary coils so that these coils may generate output voltage having mutually opposing phases basing on negative potential of DC power supply. CONSTITUTION:A first secondary coil 31S of a boosting transformer 50 generates positive voltage basing on negative potential of battery power supply 34, on the other hand, a second secondary coil 32S generates negative voltage basing on its negative potential. That is, an output part A genative voltage V1 and an output part B generate voltage V2. As a result, charging is performed while being added to a main capacitor 37 as IV1I+IV21=IVOI. Thereby, a transformer is obtained to halve a total output voltage VO to generate output volatages V1, V2 and therefore withstand voltages of the coils 31S, 32S are respectively reduced by half to make insulation treatment of a transformer extremely advantageous thus realizing a small-size.

Filed: 1986-04-07
Abstract: PURPOSE:To form an org. resin layer to a film thickness of high accuracy by forming the org. resin layer to the large film thickness until prescribed flatness is obtd. and etching the layer to a prescribed shape, then selectively etching the org. resin layer to the necessary film thickness. CONSTITUTION:An underlying film 2, a lower magnetic material 3, a gap material 4 and a conductor coil 5 are respectively formed on a substrate 1, then the org. resin layer 6 is formed. The coated film thickness of the org. resin layer 6 is determined by the flatness required for the org. resin layer 6 on the conductor coil 5. The coated film thickness varies with the coil shape, inter-coil spacing, viscosity of an org. resin, amt. of the resin, etc., and said layer is thickly coated until the required flatness is obtd. A photoresist is coated on the org. resin layer 6 and is etched after baking of a pattern. The org. resin layer 6 is further made thinner down to the required film thickness by, for example, oxygen ion milling.

Title: Facsimile equipment
Inventor: FUSHIMI JUICHI
IPC: H04N1/23
Filed: 1988-03-31
Abstract: PURPOSE:To prevent data read out of a line memory from becoming empty data so as to improve the quality of a recorded picture by changing a reading- out speed in accordance with the quantity of the data remaining in the memory. CONSTITUTION:A recording speed controlling section 206b is incorporated with a normal timer (high-speed timer) TIM1 for generating high-speed clock signals which give a normal recording speed and a low-speed timer TIM2 for generating clock signals which commands such a slow picture signal reading-out speed that can prevent the empty state of a line memory LM. Then the number of remaining picture data is compared with a preset reference number of picture data and the reading-out speeds of the recording speed controlling section 206b are suppressed by changing the normal clock signals to the slow clock signals while the number of remaining picture data is lower than the reference number. Thus the reading-out speed can be changed in accordance with the quantity of the data remaining in the line memory ML. Therefore, readout of empty data can be prevented and the quality of a recorded picture can be improved.

Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a driving mechanism capable of being reset into a driving power transmissible condition by positively releasing a transmission of driving powers during the occurrence of an excessive torque. SOLUTION: As a switch 42 is turned on, the controller 41 operates to output a signal for changing over solenoid valves 31, 32, 33. In this instance, oil pressure of a pump 30 is fed to a torque limiting device 20 so as to allow a clutch 23 to be engaged with each other. When an auger 3 is applied with excessive loads due to foreign matters put therein, the clutch 23 slides so that difference occurs in its speed between the driving side and the driven side. This is detected by sensors 45, 46, and a controller 41 serves to changing over the valve 33 so as to release oil pressure to the tank 35, and then disengage the clutch 23 for releasing torque. After removal of foreign matters, the switch 42 is tuned on, the clutch 23 is engaged again, resulting in transmission of driving powers.
