Abstract: PROBLEM TO BE SOLVED: To improve the exhaust characteristic, while securing the response at disengaging an aux. brake. SOLUTION: A fundamental fuel injection amount Tp is calculated on the basis of the engine operating condition (S1), while a max. fuel injection amount Tpmax is calculated on the basis of the aux. brake operating condition (S2), and an injection pump is controlled (S6) on the basis of the fuel injection amount Te, using either of Tp and Tpmax whichever is smaller (S3-S5).

Title: Image recording apparatus
Inventor: KIMURA HIROMI
IPC: B41J2/355
Filed: 1988-04-13
Abstract: PURPOSE:To prevent the density irregularity at the boundary between blocks, by performing recording one over another several times in order to record one line by changing over a current supply block at every gradation and supplying a current so that heat generating resistor elements become the same strobe one-several elements apart. CONSTITUTION:For example, when the recording of 64 gradations is performed by a two-division block systems, heat generating resistor elements 1 are driven alternately at every drivers IC5a-5e in the same strobe at a high speed. That is, the recording of one line is repeated up to a1-a64 while strobes 1(S1), 2(S2) are changed over at every gradation to perform lap-printing recording many times. When a recording head is driven by this method, the recording dot Km+1 at the boundary of the strobes 1(S1), 2(S2) receives the heat effect from the dot Km previously generating heat of the adjacent block to become a preheated state and becomes the same density as dots Km-1, Km+2 at a part not being a boundary end part. Therefore, no white stripe is generated at the boundary part of blocks.

Title: Formation circuit of comparing saw-tooth wave voltage for horizontal afc circuit
Inventor: IIDA MIKIO
IPC: H04N5/12
Filed: 1978-07-28
Abstract: PURPOSE: To eliminate the higher harmonic wave piled onto the horizontal flyback pulse and then to avoid the picture bend and others by preventing the conducting time of the switching element from varying with the fluctuation of the high-voltage load at the circuit which sets the conduction level.  
     CONSTITUTION: The joint of capacitors 10 and 11 is connected to the base of transistor TR16 via resistance 28 and diode 29 and also earthed via resistance 30. At the same time, the joint of diode 29 and the base of TR16 is earthed via resistance 31. As a result, the current shown by arrow i 1  flows to the base to the base of TR16 for the horizontal flyback time owing to the horizontal flyback pulse generated at joint of capacitors 10 and 11. With selection of the value of current i 2  flowing through resistance 30, the DC potential at the joint can be set freely. As a result, the piled higher harmonic wave can be eliminated, thus avoiding the picture bend or the like.

Abstract: PURPOSE:To reduce data errors due to jitters by counting the number of ''0''s between ''1''s in a reproduced signal, and deciding as an error and correcting it when the counted value exceeds (k). CONSTITUTION:An input signal 1 is inputted to a data generating circuit 2 and a PLL circuit 3. The contents of a reproduced data generating circuit 2 are held at ''1'' for a specific period when the input signal 1 rises and falls, and the clock of a PLL circuit is corrected.
