摘要:
A device for giving a desensitizing or so-called ink-repellent etching treatment in addition to a fixing/and or a drying treatment to a master plate which has been developed but not fixed yet when such master plate is prepared by an electrophotographic copying apparatus. As soon as the master plate is developed and brought to a position for introduction into the device, the device is automatically rendered operative to introduce the master plate into the device and subject the same to necessary treatments before automatically ejecting it from the device.

An extractor hood changes an air volume of a fan in response to a temperature of a cooking subject on a cooker. The hood includes an infrared sensor that detects an average temperature between the cooking subject temperature and an ambient temperature of the cooking subject, a temperature sensor that detects an ambient temperature of the cooker, a signal receiver, and an air-volume controller. The air volume controller calculates the cooking subject temperature based on the average temperature by using the ambient temperature of the cooker as the ambient temperature of the cooking subject, and then determines the air volume of a fan based on the cooking subject temperature and a cooker signal.

A luminance signal Ya and a color-difference signal Ua/Va constituting an input image signal is transferred to a frame memory (first memory) in the unit of line synchronously with its horizontal synchronous signal and written therein. A memory TG211 reads out a read-out request RRQ. The cycle of this request RRQ is a time computed based on a single vertical effective period of an output image signal Sc and the number of lines objective for rate conversion of an input image signal Sa. The luminance signal Ya and color-difference signal Ua/Va are transferred in the unit of line from the frame memory to rate conversion units (second memory) through buffers. There occurs no deflection in this transfer cycle and in each transfer cycle, the stable data transmission band can be secured.
摘要:
A current source circuit is contained in an output control IC and amplifies a feedback current produced by a photocoupler by 7 to 10 times. The current amplifier has an adequate current amplification factor and is composed of an IC. A capacitor connected to the oscillator is charged by a current amplified at the current amplifier and a period of the output of the oscillator is controlled by the charging current. A conductive period of the switching device connected to the oscillator through a driver is also controlled. Accordingly, the amount of energy supplied to the secondary side of the switching transformer is also controlled and a stable secondary dc output voltage is produced. A stable voltage control is obtained over a wide range of loads, from a light load to a heavy load. Because the current amplification factor is stable against an environmental temperature condition and has little variation, there is no abnormal oscillation of the power source circuit due to a ripple component included in the secondary dc output voltage and a stable controlled dc voltage stabilizer can be realized.

A table is detachably mounted to a fixing apparatus adjacent to and aligned with an inlet opening thereof. The table is formed with a longitudinal slot through which a pusher member vertically extends. A transfer sheet is placed on the table, and drive means reciprocally move the pusher member to push the transfer sheet into the fixing apparatus and return the pusher member to its original position.
