Title: Superdirectional microphone
IPC: H04R1/40
Filed: 1992-04-03
Abstract: PURPOSE:To turn the directivity into an acute angle and also to secure the equal directivity to the frequency by selecting the amplitude frequency characteristic of a two-dimensional filter and the proper sampling frequency that satisfy the specific conditions. CONSTITUTION:The microphones units 1-4 which are linearly arrayed with the spaces (d) secured among them convert the sound waves into the electric signals. The A/D converter means 11-14 converts the electric signals into the digital values which are inputted to a two-dimensional filter 15. The output of the filter 15 is converted into the analog value by a D/A converter means 16. The frequency characteristic of the means 16 is corrected and flattened by a frequency characteristic correction means. Then the amplitude frequency characteristic of the filter 15 is corrected so that a passing area is secured in a linear area which is shown by an equation I on a two-dimensional frequency plane expressed by the normalized time frequency f1 (-0.5<=f1<=0.5) and the normalized space frequency f2 (-0.5<=f2<=0.5) and also that the time sampling frequency fs of the filter 15 is kept in the range of an equation II respectively.

Title: Interrupting signal controller
Inventor: KATO SHINJI
IPC: G06F9/46
Filed: 1991-03-20
Abstract: PURPOSE:To make the period of an interrupting signal roughly constant irrespective of the period of an input pulse signal, in the interrupting signal controller for generating an interrupting signal in accordance with the input pulse signal. CONSTITUTION:A CPU 24 derives a period of an input pulse signal, based on a value of a free running timer 23, and calculates a frequency division ratio preset to a presettable down-counter 21, based on a ratio of said period and a period set in advance to a ROM 25. The shorter the period of the input pulse signal is, the larger value this frequency division ratio becomes. The presettable down-counter 21 frequency-divides the input pulse signal by the frequency division ratio preset by the CPU 24, and generates an interrupting signal. Even if the period of the input pulse signal becomes short, it does not occur that an arithmetic speed of the CPU becomes unable to cope with the interrupting signal.

Title: Vacuum suction device
Inventor: HASEGAWA MASAHIRO
IPC: B66C1/02
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To determine good suction so as to improve reliability by determining a normal sucking operation based on a signal indicating solenoid valve opening, a signal indicating proper adsorbing operation confirmation based on a first difference pressure set value and a signal indication improper vacuum original pressure confirmation based on a second different pressure set value during the sucking operation of a device. SOLUTION: When a device starts its sucking operation, a solenoid valve 4 is opened and, if a sucked article is adsorbed normally on an suction part 2 at this time, the difference pressure of a 2 setting difference pressure switch 21 becomes roughly 0. Then, when the solenoid valve 4 is closed, if a vacuum pump 3 is normally operated, the difference pressure of the 2 setting difference pressure switch 21 becomes equal to an attracting pressure necessary for adsorbing. At this time, if the 2 setting difference pressure switch 21 operated based on a first difference pressure set value is SW1 and one operated based on a second difference pressure set value is SW2, by combing the signal of the solenoid valve 4 with the signals of the two setting switches SW1 and SW2, the good state of adsorbing operation checking and the good stage of vacuum original pressure checking are both determined by a determination circuit 22.

Title: Numerical controller
Inventor: HORIUCHI CHIHIRO
IPC: G05B19/19
Filed: 1987-04-06
Abstract: PURPOSE:To detect the misalignment of both wheels with high accuracy by using a pulse generator and a counting means for counting its generated pulse. CONSTITUTION:As a motor 33 is driven to rotate, a moving pulse P and a zero marker pulse ZM are generated at every prescribed angle and at every one rotation, respectively, from a pulse generator 34. An UP/DOWN counter 36 counts the moving pulse P, and whenever the zero marker pulse ZM is generated, a register 38 latches it, and a register 39 latches it at every prescribed period. A CPU 1 reads the contents of the register 39, and accumulates a difference of the previous value and the present value, in an area 2A of a RAM 2, therefore, a machine origin position is set as '0' and a distance in which a machine has moved therefrom, namely, the present position is stored in the area 2A. Subsequently, the CPU 1 reads the contents of the register 38, namely, a zero marker position, and a difference between the present position stored in the register 39, and this zero marker position is stored in an area 2B. In such a way, by deriving a deviation of values of the areas 2B, 2C, a misalignment of both wheel driving can be detected surely and at a low cost.
