Title: Recording system
Inventor: OKAMURA SHIGERU
IPC: B41J2/525
Filed: 1983-04-11
Abstract: PURPOSE:To elevate the recording speed of black color, by a method wherein black color is also formed by plural recording means other than black color as color recording means. CONSTITUTION:For example, the ink of yellow, magneta and cyan are fed to plural nozzles 1, 2 and 3 for recording color on a carriage 5, and the ink of black color is fed to nozzle 4. Then, in recording black color, liquid drops are let to reach the same point by discharging then from nozzle 1-3 and the black color dot B1 by mixing color is built up on the paper. At the same time, the black color dot B2 is also built up from the nozzle 4 for black. Therefore, the black color recording time by the nozzle 4 for black only can be reduced by half and the recording speed can be raised two times.

Title: Gapped core type reactor
Inventor: KIMURA MASAYA
IPC: H01F37/00
Filed: 1985-03-29
Abstract: PURPOSE:To improve the occupation rate of a core by a method wherein the surface of the clamping plate arranged on the outside of the upper and the lower yoke cores is fastened tight using three or more clamping studs per core leg arranged at the prescribed positions on the inside and the outside of the inner and outer circumferences of the yoke cores. CONSTITUTION:The upper and the lower clamping plates 9 and 10 are arranged outside ring-shaped yoke cores 3 and 4. Three clamping studs 15, arranged at the position on the inside and outside of the inner and outer circumference of cores 3 and 4, are inserted into each core leg 2 located between the clamping plates 9 and 10, and they are fastened tight on the plates 9 and 10 using nuts 16a and 16b. According to this constitution, it is unnecessary to form a gap where clamping studs are passed through on the cores 3 and 4, and the manufacture and assembling such as a winding work, a measurement adjustment and the like can be inserted into the legs 2, the local heating on the clamping studs 15 themselves due to the flinging of magnetic flux is not generated, and there is no possibility of lowering of clamping strength due to heat expansion. Also, as it is unnecessary to form a hole for insertion of the studs 15 on the legs 2 and the cores 3 and 4, the center hole can be made small, and the occupation rate of the cores can be improved.

Title: Thermal recorder
Inventor: TAKAHASHI SHIYUUICHI
IPC: H04N1/032
Filed: 1981-04-27
Abstract: PURPOSE:To enable continuous use of a thermal recorder having a mXn dot matrix heads for a long time by providing m+n pieces of drivers and sequentially driving at every unit row or column, thereby decreasing the application rate of the head. CONSTITUTION:Data read in every n bits from a memory 11 which stores picture information data are converted into parallel data via a serial/parallel converter 13, and are then inputted to a latch circuit 14. The data of the circuit 14 is changed and drivers corresponding to rows (Dr, 1-Drm) are selected (or  shifted) in accordance with the signal of the clock 2 generated by one pulse at every n pulses of the clock 1. In this manner, recording pictures a, b, c,...m can  be sequentially obtained. Since pause time of one row becomes long in this case,  the temperature rise of the head can be suppressed, and yet since the drivers  can be enough with m+n pieces, the cost of the recorder can be reduced.
