Patent JP-H0321463-A (JP)
Title: Thermal head drive system
Inventor: KUSHIDA ATSUYOSHI
IPC: H04N1/23
Filed: 1989-06-19
Abstract: PURPOSE:To supply a constant energy to heating elements to prevent the occurrence of unevenness in density and to obtain a power source of longer life by a method wherein resistors are connected to the heating elements in parallel so that an apparent resistant value viewed from the power source can be made constant corresponding to the number of the heating elements to be electrically conducted. CONSTITUTION:Printing data is transmitted to a buffer memory 10. The data for one line is once stored and read out. Then, the data is transmitted to a thermal head 11 and successively stored in a shift register. At the completion of the data transmission for one line, a counting means 12 is reset, and repeats an action of counting bits having a logical value '0' in next data for one line. Based on the number of bits having a logical value '0' counted by the counting means 12, an impedance selection means 13 selects an impedance to be connected to a power source VD in parallel with a thermal head 11. On a strobe signal, the impedance selection means 13 opens a gate to pass a current to the selected impedance. In this manner, an electric current of an invariantly constant value can be supplied from the power source VD when data for one line is printed.

Title: Method and device for measurement of sticking intensity at connected part
Inventor: SARUGI KATSUJI
IPC: G01M7/00
Filed: 1980-11-06
Abstract: PURPOSE:To measure the sticking intensity at a connected part, by applying the exciting force inclreasing with the time lapses to give vibrations to the connected part, measuring the degree of distortion caused to a memeber and detecting a sudden displacement. CONSTITUTION:When the rotary frequency of a variable speed motor 8 is gradually increased, the momentum transmitted through a flexible shaft 7 increases to increase the vibration of an exciter 6. Accordingly, a connected shaft 2 vibrates, and a connected part 3 also vibrates. The degree of distortion of a plate 1 which is caused by the vibration of the part 3 is detected by an attached semiconductor distortion gauge 10, and the output of detection is displayed at a meter 9 via an amplifier 11 and a rectifier 12. A sudden change of the degree of distortion at the part 3 emerges in the form of a change of the degree of distortion of a component member. This degree of distortion becmes an index that shows tha sticking intensity of the part 3. At the same time, the output signal of the gauge 10 is amplified and supplied to a synchro scope 21 to be displayed in the form of a load waveflorm. Thus backlash can be decided for the connected part.

Title: Dynamic ram controller
Inventor: MIZUNO MASATOSHI
IPC: G11C11/34
Filed: 1982-09-10
Abstract: PURPOSE:To reduce the refresh requesting frequencies, by controlling the refresh after constituting a timer with an RAM and an incremental circuit and then making use of the locality and continuity of a von Neumann computer program. CONSTITUTION:A timer is constituted with an RAM 6 of a register corresponding to each refresh address number of a dynamic storage device and an incremental circuit 7. A register of a refresh address received an access is reset via the circuit 7. While the register of an address received no access is periodically clocked and decided via the circuit 7, and a refresh request is delivered from the circuit 7 to an address which reaches a fixed value. These registers are connected to a von Nenmann computer. Thus the access receiving probability is increased during an operation of a program for a row address to be refreshed. As a result, both locality and continuity of a von Nenmann program are used at their maximum. This reduces the refresh requesting frequencies and increases the processing speed of a dynamic storage device.
