Title: Frequency measuring apparatus
Inventor: KINOSHITA YASUHIKO
IPC: G01R23/10
Filed: 1992-04-27
Abstract: PURPOSE:To improve frequency measuring accuracy by setting the pulse width of a control signal at a value longer than the value obtained by adding a reference measuring period and one period of a reference clock, forming a gate signal corresponding to the control signal, and operating the frequency when the control signal is finished. CONSTITUTION:A gate control part 7 is controlled with a control signal (a) from a CPU 1, receives a reference clock (b) (e.g. 100 Hz), generates a gate signal (d) having the pulse width of a reference measuring period and sends the signal to a gate circuit 3. The gate circuit 3 receives the gate signal from the control part 7. The gate circuit 3 is opened only during the period from the initial rise-up timing of the reference clock to the next rise-up timing. A signal to be measured (c) is sent into a counter 4 and counted. The CPU 1 reads the counted value of the counter 4 at the time when the control signal falls down and operates the frequency based on the counted value. The frequency is displayed on a frequency display device 5.

Title: Thermal head driving circuit
Inventor: ENDO TETSUO
IPC: B41J2/355
Filed: 1986-06-06
Abstract: PURPOSE:To perform precise correction before delivery from a factory, by providing ROM to a thermal head to write correction data corresponding to the resistance value of each of head elements and correcting the driving pulse outputted from a shift register of the basis of the correction data. CONSTITUTION:In the writing of ROM9, a current is successively made to flow to each of head elements to be converted to the resistance value thereof and the correction rank of each of the head elements is determined. Voltage is applied to the gate of the electric field effect transistor 15 corresponding to one head element through a latch circuit by utilizing a shift register and a current is made to flow to fuses 14 from a terminal for predetermined data corresponding to the correction rank and, when the predetermined fuse 14 is fused, an H-signal is stored and, when not fused, an L-signal is stored and this operation is performed with respect to ROMs9 corresponding to all or the head elements to complete writing. A comparator 10 compares the correction data of ROM9 with the correction comparing data of a counter to output correction drive data to an AND circuit and outputs a drive pulse which is the combination of fundamental drive data and the correction drive data to each head element and, therefore, the irregularity in color density based on resistance value deviation is eliminated.

Filed: 1986-06-06
Abstract: PURPOSE:To make the required capacity of a memory small and to perform real-time processing by referring to labels of adjacent picture elements while scanning respective picture elements, and labeling the respective picture elements. CONSTITUTION:A binary-coded image is scanned successively to label the respective picture elements according to the labels of adjacent figures, and the connection states of the respective labels are checked to remove connecting picture elements when the number of the connecting picture elements is smaller than a set number. For example, if the label of one of four picture elements (a, b, c, and d) which is not in a label buffer FF for unlabeled picture elements is stored in a label buffer, the label is given to a picture element (e) as its label. When the picture element (e) is labeled, label buffers are referred to in the order of (d), (a), (b), and (c) and wen the picture element (e) is labeled, the contents of the label buffers are referred to in the order of the picture elements (d), (a), (b), and (c). When the picture element (e) is a figure and the contents of the label buffers for the picture elements are all FF, on the other hand, a unused new label is given to the picture element (e) as its label.
