Title: Half tone recording device
Inventor: YONEDA HITOSHI
IPC: G06F3/12
Filed: 1985-06-26
Abstract: PURPOSE:To minimize the drop of a resolution, to increase the number of reproduction gradations and to record a digital picture showing a smooth gradation repeatability by employing a ternary dither method. CONSTITUTION:Three types of pulse widths W1-W3 comprising a dither pattern (dither recording signal) stored in a dither ROM 11 are set in the following relationship: W1=0<W2=210nsec<W3=250nsec. This relationship of the pulse width is decided by setting previously a density pattern where the mean error ratio epsilon of a density four-gradation characteristic can be minimized. Through the use of these pulse width signals, an input picture is made to a ternary-dither with a dither matrix size of 4X4, and pseudo gradation expression is executed at 26 levels. The density change of the picture recorded by such a dither signal is extremely smooth in the overall areas of the density width, and an excellent gradation repeating characteristic can be obtained.

Title: Oil pump
Inventor: NAKAGAWA TAKASHI
IPC: F01M1/02
Filed: 1984-07-05
Abstract: PURPOSE:To aim at preventing abnormal noise, heat generation and so on from occurring, in an opening part to the inside of a housing of a discharge chamber, by making length in a circumferential direction smaller than ever before, insomuch that discharge capacity in a pump is securable, while making a pressure receiving area, where oil pressure inside the discharge chamber acts on both rotors, smaller as well. CONSTITUTION:A circumferential partition position at the side of a sealed space 21 in an opening part to a space 13 inside a housing of a discharge chamber 18 is set down to P, and making a state that the sealed space 21 becomes maximum a basis, circumferential length size l of the discharge chamber 18 is set between circumferential length size l1 up to a position P1 where gears 14a and 15a contact in the first and circumferential length size l2 up to a position where these gears 14a and 15a contact in the third, and the length size in the circumferential direction of the discharge chamber 19 is set to be smaller than ever before. In this connection, the reason that the said l is set to be larger than l2 is to secure discharge capacity in a pump of the discharge chamber 18. With this constitution aforesaid, a pressure receiving area of oil pressure acting on both rotors 14 and 15 becomes smaller whereby tooth surface pressure drops, thus abnormal noise, friction, heat generation, etc., are all preventable from occurring.
