IPC: G11B5/64
Filed: 1983-06-08
Abstract: PURPOSE:To improve a coercive force sharply by adding a prescribed rate of Pr to an alloy of a prescribed composition of Pt-Co. CONSTITUTION:Using a target material prepared by adding Pr to a Co-Pt alloy having a composition of Pt 9% and Co 91% in the atomic ratio, a thin film of a Co-Pt-Pr alloy is manufactured by a spattering method. The film thickness of the thin alloy leaf thus obtained is about 3,000Angstrom .

Title: Method and device for buffer control for real time voice communication
Inventor: KOMATSU TADAHIKO
IPC: H04L49/9023
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a missing packet and an interrupted voice signal independently of fluctuation in a network. SOLUTION: A reproduction control module 3-8 monitors a data storage amount of a reception buffer 3-2. When the data storage amount exceeds a threshold L1, a high-speed reproduction module 3-3 thins buffer output packets to obtain high-speed data thereby decreasing the storage amount of the buffer 3-2 and reducing a delay time. When the data storage amount is less than a threshold L2(<L1), the output from the reception buffer bypasses the high-speed reproduction module 3-3 to obtain a usual reproduction speed.

Filed: 1992-03-27
Abstract: PURPOSE:To provide a print control system of printer by which to prevent a data receiving/processing time from decreasing following the acceleration of processing time by a printer. CONSTITUTION:The printing control system is to output a time pulse signal a timer 7 based on a calculated value obtained by calculating the operating conditions of a carriage and a print head, then perform a spacing interruption process which is appropriate for said time pulse signal, and control the printing performance of a printer through an impact interruption process within an equal speed transit section where the carriage moves in the acceleration, equal speed and speed reduction mode. Further, the remaining count number of the time pulse signal is set in a counter 18 at the end point of the transit section in the acceleration mode, then the spacing interruption process is inhibited in the transit section in the equal speed mode to perform the impact interruption process by the count pulse of a timer 17 for printing. Thus a receiving code for a next line of data is loaded during an unoccupied process time. Consequently, it is possible to load the receiving code for a next line of data rapidly in response to the acceleration of process time by a printer.

IPC: F02D41/06
Filed: 1981-06-29
Abstract: PURPOSE:To improve wettability of an ignition plug as well as to elevate the starting qualities of an engine, by installing a throttle opening device and a fuel controlling device to control a fuel-injection quantity spouted out of a fuel- injector by operation of a cranking detecting device. CONSTITUTION:An electric fuel-injector 1 is governed by a control unit 2. In time of cranking, when throttle valve opening is operated too much beyond the fixed value, both contacts 5a and 6a of a throttle opening device 5 and a cranking detecting device 6 are closed together. With this, an output of an NAND circuit 8 becomes a low level and thereby a transistor 9 of a fuel control device 7 comes into a state of non-conductivity, i.e., 'OFF' period. As a result, control signals to the fuel-injector 1 from the control unit 2 is shut off, stopping the fuel-injection so that wettability of an ignition plug may be much improved, bedises improvement in engine starting properties.
