Abstract: A punching transport apparatus attached to an end surface a cylindrical inner surface drum includes two transport units which are connected with a pulse motor, two belts, and two pulleys so as to be able to move in synchronism to each other. The two transport units are linked to two punching units through linkage blocks. Transport carriers of the transport units are threadingly engaged with ball screws which are linked to the pulleys so that the transport carriers are loosely fitted to guide rails. Receiving an input signal which is entered in accordance with a plate edge distance which is determined by the specifications of a printer, a controller drives the pulse motor under the control of a pulse count. As a result, from an origin position which is determined in accordance with a condition which is detected by an origin sensor, the two transport units and the two punching units move in a central axis direction X.
Abstract: An image recording apparatus compares the memory size for storing image data corresponding to an image to be recorded with a recording sheet size designated by a recording sheet size designation command included in printing data output from an external apparatus. If the recording sheet size exceeds the memory size, the apparatus forms image data in a resolution lower than a normal resolution and stores the data in the memory. On printing the image in accordance with the stored image data, the apparatus multiplies the data in the memory and records the image in the initial resolution.
Abstract: A photosensitive material is mounted onto an inner surface of a cylindrical inner surface drum. An input signal which provides the size of the photosensitive material is supplied to a controller. As the controller drives a pulse motor under the control of a control signal, a moving part with which punching units are connected is moved in a circumferential direction of the drum by means of the pulse motor and positioned at the desired positions for punching. Then only two punching units, determined by the controller in accordance with the size of the photosensitive material, are driven to punch holes in the photosensitive material.
Abstract: An image recording system includes a host computer and a recording apparatus. The host computer generates image data to be recorded as an image. The recording apparatus includes a recording head, an image data generator, an error detector, and a selector. The error detector checks the condition of the recording apparatus to detect any errors. The selector switches between an on-line mode and an off-line mode of the recording system. In the on-line mode, the recording head is capable of recording the image on the recording medium in response to the image data supplied from the host computer. In the off-line mode, the recording means is capable of recording the predetermined image on the recording medium in response to the predetermined image data supplied from the predetermined image data generator. The selector switches to the on-line mode when the error detector does not detect an error and switches to the off-line mode when the error detector does detect an error.
Abstract: A print head, formed with spaced linear subheads of jet nozzles, prints all of the lines or image element rows on a print medium such as a sheet of paper by scanning along the face of the sheet. The head is advanced between scans by an equivalent number of lines generally equal to the number of nozzles in the head, whereby all print lines are addressed only once. Apparatus for printing includes the use of pointers in registers to keep track of head structure and location on a print medium for calculating print addresses. A partial page memory is used which wraps around to the beginning from the end. An edge sequence control logic circuit modifies the print data so that nozzles not over the image area do not print. A positive printer carriage position encoder uses an index marker located in the middle of a strip of incremental markers. Sensing of the index marker resets an up/down counter with a value that gives a positive value for all count conditions.
Abstract: A method of creating a self-documenting logfile which records the status and operation of a substantially computer-controlled device.

In order to comply with good laboratory practices (GLP), the method additionally comprises steps for verifying the user input commands by determining the acceptability of the input commands, detecting inadvertent alteration to the logfile and testing the validity of the logfile for invalid data. Steps for providing an enciphering key within the event lines which comprise the logfile in order to detect tampering are also disclosed.

Abstract: Method, apparatus, and system are described wherein dot matrix characters are formed by an array of ink spray nozzles within a marker head assembly upon the inside surface of a pipe or other curved surface. The marker head is moved by a traversing arrangement including a carriage in a manner wherein full character pixels are formed during movement of the marker head along locii parallel with the longitudinal axis of the pipe being marked. This achieves full messages marking with a minimized number of required marker head movements along the inside surface. An indexing mechanism engages the outer surface of the pipe to index it from one marking locus to a next. A translational mechanism moves the marker head traversing mechanism from off-line to on-line positions at the production path during the course of operation of the system.
Abstract: An electronic remote data recorder records pulses representing usage of a commodity such as, for example, water, gas or electricity from a plurality of consumers. The data from each consumer is stored in a respective data storage device. Each data storage device is associated with an interval data directory which stores the times at which significant events, affecting the data in the data storage device occurred. Thus, the data in the data storage device is compact, without requiring a contemporaneous time code for each data item. Data integrity is retained over a period of power outage in a non-volatile storage device. Initial, post-installation programming is enabled by comparing the data pattern in the non-volatile storage device with a predefined data pattern that is expected to exist once the apparatus has been programmed. A write-protect switch prevents programming during an incoming call after the initial programming.

Abstract: A printer interface circuit is provided in a host system so as to allow a printer having its own clock signal for its printing operation to be directly connected to the host system. In the present invention, data to be printed is first stored in a data latch as supplied in association with the clock signal of the host system, and then the data stored in the data latch is transferred to the printer in association with the printer. Thus, even if use is made of a laser printer, which has its own clock signal, it can be directly connected to a host system, such as a personal computer. In the preferred embodiment, the printer interface circuit modifies the frequency of the clock signal of the printer and the data is transferred to the printer at this modified frequency, so that the data may be expanded when printed.

The apparatus includes a primary indicator, responsive to an operation of one or more of the selector keys to change at least one of the at least two recording conditions from one recording mode to another, for displaying a single special symbol to indicate the change of the at least one recording condition, without specifying the changed recording condition or conditions and the newly selected recording mode or modes of the changed condition or conditions.
Abstract: An apparatus records fluid level movement using a potentiometer that is rotated by a tape attached to a float and a counterweight. The output from the potentiometer is recorded by a microprocessor which is presettable for desired time intervals. Static friction in the moving parts causes small fluid displacement to go unrecorded until they accumulate to produce a larger rotation of the potentiometer, resulting in inaccurate data recording termed "staircasing." To overcome staircasing, before a reading is taken, an impactor made up of a solenoid with a spring-loaded core impacts the tape with sufficient magnitude such that the resultant movement and oscillation of the tape will overcome the static friction, resulting in a smooth, accurate data record.
