摘要:
Discharge of a high-pressure gas-occluding liquid from a pressureproof container holding therein said liquid in a compressed state is effected by a method which comprises connecting said pressureproof container through the medium of a valve to a pressureproof receptacle, allowing the liquid to transfer into said pressureproof receptacle, diminishing the pressure within said pressureproof receptacle for thereby separating the occluded high-pressure gas from the liquid and subsequently releasing the liquid alone from the receptacle. For the purpose of said discharge, there is used a device which comprises a pressureproof container, a pressureproof receptacle and a valve through the medium of which said pressureproof container and said pressureproof receptacle are connected, said pressureproof receptacle being provided in the upper portion thereof with a piston adapted so as to have the motion thereof limited via a valve by means of a spring and in the inner portion thereof with a liquid discharge tube laid past a piston and a valve.

An apparatus for the transfer of powder into a high-pressure vessel comprises a cylinder, two pistons disposed one on top of the other inside said cylinder and two openings formed in the circular wall of the cylinder, the one opening serving as an inlet for entry of the powder and the other opening serving as an outlet for exit of the powder into the high-pressure vessel. The transfer of powder from the powder hopper into the high-pressure vessel by use of said apparatus is accomplished by a method which comprises connecting the inlet of said apparatus to the discharge tube of the powder hopper and the outlet of the apparatus to the powder lead tube of the high-pressure vessel respectively, driving the two pistons so as to interpose a space therebetween communicating with the inlet opening, then moving the pistons in unison for thereby causing said space to move down the cylinder interior to a position in communication with the outlet opening so that the powder in the space can fall into the high-pressure vessel and then driving the pistons together to eliminate the space between them.

An image input-output apparatus is provided with a printing function for printing an image specified by print data from an external device and a reading function for reading an original image. The apparatus includes a printing function realizing unit, a discrimination unit, and a control unit. The printing function realizing unit operates in a first mode for realizing the printing function with a relatively small memory capacity and operates in a second mode for realizing the printing function with a relatively large memory capacity. The discrimination unit discriminates whether printing of the image specified by the print data is to be realized by the first mode or the second mode. If it is discriminated that printing is to be realized by the first mode, the control unit is adapted to allow parallel execution of the printing function and the reading function. Otherwise, parallel execution is inhibited.

Print data including text or graphics data is transferred from a host computer to a printer. The printer develops the received data on a band basis. When data processing to be performed by the printer is expected to fail due to shortage of the memory area size, the host computer cancels the data which has already been sent to the printer, and develops the text or graphics data to form image data. The image data thus formed is sent to the printer. Image data is transferred in a hierarchical manner. Disclosed also is a method which makes it possible to eliminate as much as possible any data processing failure in the printer attributable to shortage of memory capacity.

If an optional paper feeding deck or furnisher, or paper stacker, is connected to an image forming apparatus (such as a printer), such optional devices are to be controlled by connecting the paper conveyance control apparatus to control those options. Such an image forming apparatus has a video controller to convert the printer language sent from a high-order device such as a host computer, into bit map data and a printer engine to print the bit map data. Such a paper conveyance control apparatus, being electrically connected to the video controller, has a memory to be shared with the video controller. The video controller writes the job schedule in the shared memory. The paper conveyance control apparatus controls the optional device according to the written job schedule.
摘要:
An input/output device comprises a first controller for controlling input/output of information, an interface provided between the first controller and an information exchange unit, and a receiver for receiving data inherent to the interface from the interface. A discriminator discriminates whether data received by the receiver is one registered in the first controller, and a second controller inhibits the exchange of information between the interface and the first controller when the discriminator discriminates that the data received by the receiver is not one registered in the first controller.
