Title: Automatic sewing device
Inventor: TACHIKAWA OSAMU
IPC: D05B19/10
Filed: 1991-08-09
Abstract: PURPOSE:To enable a pattern before sewing to be confirmed by causing the inching motion of a cloth presser device and a machine at every stitch, performing a calculation about the next shift direction from present, previous and next seam positions, and generating a warning and display, when the next shift direction deviates from the previous shift direction by the predetermined angle or more. CONSTITUTION:Seam line data shown by displacement in X and Y directions at every stitch is saved in a floppy disk. When the present seam position is at (n) due to displacement as a result of inching operation, the cos theta of an angle theta formed with DELTAxn and DELTAyn and DELTAxn+1 and DELTAyn-1 is calculated, and compared with a constant value alpha. This value alpha is a maximum bend angle not generating a warning, and alpha=cosS. The bend angle thetaa of a seam (n + 1) next to the present seam (n) is less than S, and no warning is generated. In the case of a seam (n + 1)', however, a bend angle thetab is larger than S, and a warning is generated. According to this system, a sewing machine is inched with a jog key, according to the seam data, and confirmation can be made before sewing as to whether the presser plate of a cloth presser device agrees to selected seam data.

Abstract: PURPOSE:To suppress the self-convolution and to improve the characteristic and the efficiency by exciting the surface acoustic wave in opposite phase in an adjacent element from one of exciting electrodes in pairs and forming a waveguide path with plural elements corresponding to each element of an interdigital electrode. CONSTITUTION:With an electric signal F(t)exp(jomegat) whose center angular frequency is omega given to one input interdigital electrode 2, the surface acoustic wave is propagated through waveguide paths 4-1-4-n in the direction X being the forward direction and reaches the other input interdigital electrode 3 in the same phase while an electric signal G(t)exp(jomegat) whose center angular frequency is omega given to the other input interdigital electrode 3, the adjacent element is excited so that the phase is made opposite and the elastic surface acoustic wave is propagated through the waveguide paths 4-1-4-n in the direction opposite to the direction X being the reverse direction. Then the wave reaches the electrode element of the input interdigital electrode 2 while the phase is made opposite. Thus, the surface acoustic wave reaching the electrode is neutralized electrically, resulting that no reflection wave due to re-stimulation is caused.

Title: Pachinko game machine
Inventor: NAKAJIMA HIROSHI
IPC: A63F7/02
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a pachinko game machine such that an illegal act using a 'hanging board' and the like can be prevented by making it impossible to find the timing of the occurrence of a jackpot. SOLUTION: In the case of a first processing (S1: Yes) since the turning on of power, first a RAM is initialized (S2), and then a value in an initial value memory is written into a random number counter (S3). Since the value in the initial value counter is made variable by an initial value memory renewal process, the initial value for the renewal of the random number counter can be set to a changed value from 0 to 20 by being written into the random number counter. Thereafter, a random number counter renewal process (S10), each process (S4), and an initial value memory renewal process (S20) are executed in that order, whereby a reset interrupt process for that cycle is terminated. Thus by making variable the initial value for the renewal of the random number counter, it is made impossible to find the timing of the occurrence of a jackpot with the use of a 'hanging board', etc.
