IPC: B41F3/81
Filed: 1985-11-22
Abstract: PURPOSE:To prevent a swelling of ink on a printing plate from adhering to a blanket by providing an intermediate stop point between the upper and lower stop points of a lifting ink doctor blade with respect to an intaglio. CONSTITUTION:A doctor blade 7 is enabled to ascend and descend by a cylinder 5.

Patent JP-H0579437-A (JP)
Title: Controller of engine
Inventor: SATO HIROSHI
IPC: F02P3/045
Filed: 1991-09-13
Abstract: PURPOSE:To generate an ignitor control signal suitable for engine rotation by using simple hardware constitution. CONSTITUTION:An ignitor control signal IGT which controls current carrying of an ignitor coil is generated based on the ignitor control signal IGT synchronized with crankshaft rotation. A counter counts up the fixed clock in the first half cycle T1 and counts down in the latter half cycle T2. A prescribed correction d1 is subtracted from counted value Cm at count inversion time t2 and count down action is carried out using Cm-d1 as the initial value. The signal IGT is raised at the time t4 when a counted value of the counter reaches the fixed threshold alpha0, and the signal IGT is lowered at the ending time t3 of cycle T. The most suitable pulse width (t) is obtained because the correction d1 varies inresponse to engine speed.

Filed: 1987-10-19
Abstract: PURPOSE:To enable generation of a halftone dot pattern of any large size at high speed by generating a periodic halftone dot pattern decided exclusively by a dot gradient indicating a halftone dot angle or loading a periodic pattern generated in advance. CONSTITUTION:The period (a<2>+b<2>) of a halftone dot pattern is set in an X address generation circuit 109 and a Y address generation circuit 110 through a clock generation/timing control circuit 105. Consequently, a periodic halftone dot pattern in a square region with one side of (a<2>+b<2>) dot size is repeatedly read from a halftone dot pattern storage memory 108. As a result, a halftone dot pattern of any large size is generated and entered into a data conversion table memory 112. A series of density image data is read from a line buffer and entered into a comparison circuit 114, passing through a selector 117. After this, the data is compared with the above-mentioned halftone dot data in terms of size and the comparison results are output in bits serially. These serial bits are converted to parallel bits by a shift register 118 and this data is sent to a laser beam printer 119 to record a halftone dot image.

Title: Lsi designing device
Inventor: ISHII NAOKO
IPC: H01L21/82
Filed: 1986-11-07
Abstract: PURPOSE:To design an LSI satisfying characteristic specifications in a short time by applying an optimum designing method to a logical design and function design that require extremely labor and time. CONSTITUTION:LSI characteristics (y) is approximated by a function formula including a design parameter (x) and the optimum design parameter satisfying the target specifications is extracted out of said function formula by a design means. A CAD system applying the maximum design parameter comprises a simulation means for timing, logic and function designs that require the largest manpower and the longest design period. Thus the LSI designing manpower and designing period are extraordinarily reduced. In this system, P pairs of LSI characteristics are obtained with respect to P pairs of design parameters given in the form of a design matrix produced by desired procedures. Thus a LSI characteristic simulator group is carried out by P times. Based on these execution results, a model parameter is produced for a function approximating expression of the characteristic (y) to the parameter (x).

Next, the unit 4 receives the discrimination code of the tag 1 transmitted from the unit 2 to renew the content of the memory apparatus contained and to display the same on each display unit 5. Therefore, it can be recognized where point the moving body having the tag 1 of the specific discrimination code is present now. Because the unit 2 can read the discrimination code in the tag 1 in a non-contact state, code input is automatically performed and reliability can be enhanced.
