Abstract: PURPOSE:To attain to enhance productivity and reliability, by providing a means for selecting and setting a driving condition preset at every kind of a recording head or a maker on the basis of the discrimination code of a discrimination code generating means. CONSTITUTION:When a recording head A is assembled in an apparatus main body B and a power source is closed at the time of assembling, circuit driving voltage Vcc is supplied to the recording head A from a power source circuit 13 and preset discrimination codes ID1, ID2 are generated from a discrimination code generation circuit 5. CPU6 introduces the discrimination codes ID1, ID2 through an input/output circuit 12 and discriminates the maker of the recording head A from the signal levels of said codes and selectively read the driving condition optimum to the discriminated maker from ROM7 to set the same to RAM8 and, thereafter, transfers to recording control operation. Therefore, the current supply recording pulse width optimum to the recording head A is set and a current is supplied to each heat generating resistor to drive the same. As a result, the heat generating resistor receives current supply driving under an optimum condition without exceeding rated power and the erroneous setting of a driving condition can be certainly prevented.

Title: Four-sheel driven car
Inventor: MATSUMOTO YASUHEI
IPC: B60K17/34
Filed: 1986-03-25
Abstract: PURPOSE:To desirably vary the distribution of torque between front and rear wheels while traveling at the time of four-wheel driving and improve traveling performance by connecting the output side of a transmission to both front wheel side and rear wheel side via hydraulic clutches respectively and separately controlling the hydraulic pressure of both of said hydraulic clutches. CONSTITUTION:When driving with four wheels, a signal with large duty ratio is sent to both solenoid valves 40, 40' from a control unit 44, setting s signal oil pressure small. Thereupon, clutch oil pressure control valves 35, 35' generate high clutch oil pressure and feed the pressure to both hydraulic clutches 20, 20' respectively, causing both clutches 20, 20' to be engaged. As a result, the power from the output shaft of a transmission 4 is transmitted to the front wheel side via a front side drive shaft 14 and a differential unit 16 while also transmitted to the rear wheel side behind transfer gears 19, 21 and a rear drive shaft 22. At a medium or low speed area, for example, the torque distribution is made in such a way that the hydraulic clutch 20' has a higher oil pressure and torque, to obtain a travel mode close to that of an FR car.

IPC: G05B19/416
Filed: 1988-03-24
Abstract: PURPOSE:To attain precise positioning control by automatically and continuously selecting an optimum pattern as a preparation function in consideration of the result of past positioning control. CONSTITUTION:A preparation pattern selection part 13 generates a pattern selection signal SEL selecting the optimum pattern among respective preparation patterns 1-n based on an actual slippage SD detected in a slippage detection circuit 20 and a speed Va when a brake ON signal which a latch circuit 21 latches is generated.

Thus, the slippage compensation quantity given as the preparation value and the actual slippage quantity make not so much difference, and positioning control with less difference is continuously attained.
