Title: Method for extracting frequency component of temporally fluctuating data
Inventor: MATSUI KAZUNARI
IPC: G06F17/14
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To realize high speed processing and a circuit with a small-sized scale by simplifying an arithmetic operation to extract data consisting of frequency components synthesized with temporally fluctuating data. SOLUTION: Data P(i)-T(i) are generated by each of capitation data resulting from applying 1/2, 1/3, ..., 1/n equal division to discrete point data D(i) of a synthesis signal in a time base direction and from applying superposition summation to each of the capitation data with the united time base, and the data P(i)-T(i) are respectively divided (10) by the corresponding equi-division number.  The discrete point data relating to a signal component with a frequency of a multiple of x (x is a natural number; 1<=x<=n) of a fundamental frequency of the synthesis signal are obtained by using the discrete point data D(i) and summed data 1/2*P(i)-1/6*T(i) after the division and by subtracting (11) repetitively the summed data after the division corresponding to an integer multiple x (2 or over) from the summed data (discrete point data of the synthesis signal in the case of x=1) whose equal division number is x in a direction of the time base.

Title: Ic test circuit and programming method
Inventor: BURUUSU ANDORIYUU DOIRU
IPC: G11C29/52
Filed: 1990-09-28
Abstract: PURPOSE: To reduce test time by writing constituent information during a test, only in a nonvolatile storage device and a relative latch. CONSTITUTION: A nonvolatile storage element 20 is programmed by the signal application of a programming transistor switch 22. A signal PROGRAM turns on a switch, thereby applying the value of a signal BIAS to the element 20. A latch 24 is connected with the element 20 and a transistor switch 26, which is changed over from OFF to ON by the value of a signal SET and applies the value of the signal BIAS to a latch 8. Only during the programmable logic device test, the latch 8 is used. Values in the latch 8 which are stored during the test provide a signal ARCH-BIT. Values in the element 20 which are stored during the ordinary programming and device operation form the signal ARCH- BIT, and the latch 24 is not affected. The latch 24 is a nonvolatile device, enables high speed storage, and can reduce the test time of a device.

Title: Encoder
Inventor: TSUKADA TOSHIRO
IPC: H03M7/00
Filed: 1984-12-07
Abstract: PURPOSE:To obtain an output at a high speed corresponding to an input by constituting a dynamic encoder of two output lines, and catching at a high speed a voltage level variation generated in one of them by a sample holding type comparator. CONSTITUTION:When a clock CLK is 'L', a PMOS1 and an NMOS3 are turned on, and all signal lines l1-lN, l1'-ln' are charged to 'H' and 'L', respectively. In such a case, all signal lines k1-kM, k1'-kM' are fixed to 'L', 'H', respectively. Also, a sample holding type comparator is biased to an intermediate level, when a switch 6 is turned on. When the clock CLK goes to 'H', a voltage level of a signal line lk corresponding to a varied line among input lines (ink) is varied, but since the sample holding type comparator starts a variation from the intermediate level, the time varied to a threshold value is shortened, and the output can be executed at a high speed.

IPC: E02F9/24
Filed: 1993-09-20
Abstract: PURPOSE:To enhance safety by interlocking/connecting an opening and closing guardrail erected in front of an operation part with/to an opening and closing operation lever arranged in the operation part, and opening and closing the opening and closing guardrail by operating this lever. CONSTITUTION:The tip of a push-pull wire 56 is connected to a rotary lever 55 arranged protrusively on a rotary shaft 54 of an opening and closing guardrail 52. Next, a base end of the wire 56 is connected to an opening and closing operation lever 58. Next, when the guardrail 52 is closed, the operator's feet side is protected, and when an operator gets on and off a work machine, a lever 58 is operated upward, and the guardrail 52 is opened. An interval between a side end part of the guardrail 52 and the front side end of a seat 41 is widened, and becomes convenient for getting on and off the work machine. Since clothes or the like of an operation seat can be prevented from touching with a kind of operation lever 43 arranged on an armrest 42 of the seat 41, a danger that a travel part or an excavating part is suddenly actuated can be prevented. Thereby, the operator can safely get on and off the work machine.

Abstract: PURPOSE:To prevent frequent start and stop of a heating source for efficiently performing heating operation by a method wherein the heating source is not brought in operation again until the water level in a hot-water storage tank drops below the specified water level after the hot-water tank becomes full and the heating source is stopped once. CONSTITUTION:A heating source 2 is not brought in operation again until the water level in a hot-water storage tank 1 drops below the specified water level after the hot-water tank 1 becomes full and the heating source 2 is stopped once. As the heating source 2 is not brought in operation again until the water level in the hot-water storage tank 1 drops below the specified water level after the hot-water tank 1 becomes full and the heating source is stopped, the heating source 2 is not frequently started and stopped after the heat source 2 is stopped once. Moreover, as the water level in the hot-water storage tank 1 is below the specified water level when the heating source is put in operation, the operation of the heat source 2 will last for relatively a long period of time, resulting in an efficient operation of the heating source 2.
