Title: Recording data generating device
Inventor: SHIMADA YASUO
IPC: B41J2/52
Filed: 1994-05-13
Abstract: PURPOSE:To record image data in multi-gradation regardless of simulation while forming unit group data with a few number of dots. CONSTITUTION:Data for two lines are read by a shift register 62 from an image dot data memory 53a. A 2X2 unit group data signal commanded by a window W is sequentially read from the shift register 62 sequentially in the main scanning direction and the processing 61 converting the unit group data into 16-bit recording data is repeated by two lines. A mode recording recording data by two lines by a recording means or a mode inhibiting recording of recording data by one line is selected by a command form a setting mode register 67. As a result, the data are recorded at a lower density than that of the former 2-line recording mode by inhibiting the recording of one line in the latter mode and the number of gradation is expanded.

Filed: 1980-09-10
Abstract: PURPOSE:To prevent high temperature startability from its deterioration in such a way that a closing valve which is provided on a return path is closed in order to force fuel in, under the condition to produce vapor lock. CONSTITUTION:When a starter switch 15 is turned ON, a relay 16 is closed. While it is involved in high temperature starting, a temperature sensor 18 is also turned ON. When alcoholic concentration in fuel which passes through a fuel path 6 is high, since electric current value which has output from an alcoholic concentration sensor 11 through a converter 13 has grown to be large, a relay is also turned ON. In result, a closing valve 10 which is provided on a return path 7 is closed and given impetus, and fuel pressure at the time of cranking is increased. Fuel which has been fed out of a fuel pump is forcibly fed into a fuel injection valve, so that deterioration of high temperature startability in the wake of vapor lock occurrence can be prevented.

Title: Communication interface circuit
Inventor: KARASHIMA NOBUHIDE
IPC: H04L13/08
Filed: 1984-06-18
Abstract: PURPOSE:To improve the reliability of a communication interface circuit by using two buffer circuits for emergency and normal uses and giving priority to the communication data stored in the emergency buffer circuit to execute with no delay the real time processes such as the cancel of the preceding data, etc. CONSTITUTION:A data deciding circuit 6 decides whether the communication data received by a communication interface 1 is equal to the emergency or normal communication data. The normal communication data is stored temporarily to a reception buffer circuit 2A; while the emergency communication data is stored temporarily to a reception buffer circuit 2B respectively. The stored emergency and normal communication data are transmitted to a terminal device 5 via an interruption request line INT-L and a control bus CT-BUS respectively. Then a data bus D-BUS is used to read those data. An interruption is applied for the emergency communication data to eliminate delays. Thus the modulation is prevented for the overall working of a system. This improves the reliability of a communication interface circuit.

Filed: 1993-04-28
Abstract: PURPOSE:To make it possible to drive a load without consuming the kinetic energy of the load and without being affected by power source anomaly such as power interruption and open phase by installing a chopper between a DC circuit and a capacitor. CONSTITUTION:An energy storing capacitor 16 with a capacity of C2 is kept to a discharge state where the voltage is almost zero during load operation. The load begins to decelerate by a deceleration command, the kinetic energy is converted into power, and a voltage Vc1 of a DC main circuit rises. When this voltage reaches the upper limit value of DC voltage, a transistor 11 for a step-down chopper turns on, and a current iL flows to a reactor 15 and the capacitor 16 is charged. Next, if the acceleration begins, the DC voltage decreases. If the voltage drops to a value set slightly higher than the peak value of rectifying voltage from an AC power source, a transistor 12 turns on and the current it flows from the capacitor 16 to the reactor 15. When this current exceeds the upper limit, the transistor 12 turns off and the current is supplied to a DC circuit through a diode 13.
