Title: Mode switching method of microfilm loading
Inventor: OKANO TAKESHI
IPC: G03B23/02
Filed: 1983-07-27
Abstract: PURPOSE:To switch modes automatically by detecting whether data corresponding to a frame of a cassette exists or not when a microfilm is loaded. CONSTITUTION:In a step SP1 where the cassette is set to a microphotographic device having four functions, namely, photographing, picture forming processing, projection, and retrieving functions, a microswitch 4 is operated by the cassette to activate the device. After a step SP2 where tape information of the cassette is read by a magnetic head and is stored in an RAM, it is discriminated whether data corresponding to a frame exists in the RAM or not in a step SP3. In this case, if one-frame componets of data are not recorded at least, the film is jugged to be a raw stock, and the mode is switched to a camera mode SP4; but if they are recorded, the mode is switched to a read mode SP6, and thus, modes are selected automatically.

Abstract: PURPOSE:To provide a stable cooling operation under a low temperature by a method wherein a branch pipe is installed at a discharging pipe of a compressor, the branch pipe is provided with a solenoid valve and then a flow dividing pipe is mounted at a part out of the solenoid valve. CONSTITUTION:At a low temperature where a sensor 30 may operate, a solenoid valve 32 is opened, a refrigerant discharged out of a compressor 27 is divided to flow as a refrigerant flowing toward a condensor 21 and another refrigerant flowing to the solenoid valve 32 through a branch pipe 29 and one of the refrigerants is sent to a merging point 35 acting as an outlet of the condensor 21 through a check valve 34 so as to control a flow rate in the condensor 21 and decrease its capability. The other refrigerant passes from a flow dividing pipe 33 through a bypassing pipe 37. Accordingly, at a capillary tube 38, gaseous refrigerant passed through the solenoid valve 32 is mixed with the liquid refrigerant flowed from the condensor 21 so as to accept an expansion step. In addition, the gaseous refrigerant is mixed at the merging point 36 so as to increase a temperature of the refrigerant in an evaporator 22. Due to this fact, a flowing-back of liquid in the refrigerant in the compressor 27 is eliminated and then a safe operation of the compressor 27 can be carried out.

Abstract: PURPOSE: To properly control a transient ignition timing for an improved operation performance by varying an integral time constant according to an error between a required value and an actual value of an ignition timing, or varying speeds of an operation variable related to the error.  
     CONSTITUTION: A counter 105 sends an actual value of an ignition timing from a crank angle sensor 21 to a DA converter 106 and a differential amplifier 108. A required value calculating circuit 107 determines the most applicable required value IT 5  of the ignition timing from a unit pulse IS 3  and a sleeve position signal IS 9  to output. A variable time constant integrator 109 automatically varies an integral time constant according to an error ΔIT.
