Title: Counter of information record reproducing device
Inventor: HARIGAYA ISAO
IPC: G11B27/10
Filed: 1980-09-24
Abstract: PURPOSE:To correctly know the used anount of recording media even when a plural number of recordung media are removed or reloaded, by making an arrangement so that counting of used amount of media may be made continuously even when the recording medium is switched to another one. CONSTITUTION:Contents of counters 13-16, 17-20, and 21-24 are input into comparators 33-36 after selected at multiplexers 29-32 by selecting contact points of a rotary switch 3, and compared with the content of digital switches 25-28. When those two inputs coincide, an NAND gate 45 outputs an L-level and counting of the counters is stopped. The inverse signal of an inverter at this time is input into an AND gate 49, and, when the recording medium is removed, the output of the gate 49 is inversed by receiving the signal generated from a switch 52 and the AND and the counters are reset. When a medium is removed while it is used, the output of the gate 49 will not be inversed even when a switch 50 is turned on, and, therefore, the counters are not reset. Therefore, the content at the time of removal of the medium is stored and maintained.

Title: Liquid fuel burning system and atomizer
Inventor: ORITA HISAYUKI
IPC: F23D17/00
Filed: 1995-05-31
Abstract: PURPOSE: To stabilize a flame in a furnace by calculating the pressure differences between the pressure of a combining unit and the supply pressures of liquid fuel and an atomizing medium, and so regulating the flow rates of the fuel and the medium via flow rate control valves that the differences become predetermined values. CONSTITUTION: The pressures measured by an oil pressure gage 13, a vapor pressure gage 13a of an oil fired atomizer 5 and an oil and vapor combining point pressure gage 16 are read by a controller 21. The differences between the oil supply pressure and the combining point pressure and between the vapor supply pressure and the combining point pressure are calculated. Rational pressure differences are output from a previously input control data memory 22, and an oil flow control valve 8 and a vapor flow control valve 10 are operated. The flow rate is so regulated that the pressure difference of the oil and the vapor becomes equal to the required rational pressure difference by the operation.  Since the combining point pressure is at the position for atomizing the fuel, it is predicted that the aging change of the pressure is increased, but a computer is introduced to the controller 21 and the memory 22 to follow up the aging change.

Title: Engine speed control device for internal combustion engine
Inventor: NISHIKAWA SEIICHIRO
IPC: F02D41/16
Filed: 1992-05-26
Abstract: PURPOSE:To prevent engine speed from dropping far below the target engine speed by causing an engine speed control device for an internal combustion engine to switch over to feedback control when the engine speed, which had risen in excess of the target engine speed by means of a calculated control, gradually comes down and reach the specified range near the target engine speed. CONSTITUTION:An air quantity regulating valve regulates the air quantity in a bypass passage bypassing a throttle valve of an internal combustion engine. A calculated increase quantity means establishes the opening of the air quantity regulating valve to a larger calculated opening than the target opening when required. On the other hand, a calculated control means gradually reduces the opening of the air quantity regulating valve in a specified proportion and makes it access to the target opening. Further, an engine speed control means controls the opening of the air quantity regulating valve based on the difference between the engine speed detected by an engine speed detecting means and the target engine speed. In this case, an opening control of the air quantity regulating valve is caused to switch over from the calculated reduction means to the engine speed control means by virtue of a switchover means when the engine speed has reached the specified range near the target engine speed.
