Title: Moving average value digital operation control
Inventor: AOTSU HIROAKI
IPC: G06F17/18
Filed: 1979-10-01
Abstract: PURPOSE: To reduce the rupple component rate included in the output, by giving a constitution where a specific condition is established between the number of processed data for calculation of a moving average value and the sampling interval of data.  
     CONSTITUTION: AC voltage (x) is converted to digital quantory x' at the sampling timing from sampling timing control unit 2 by A/D converter 1. Output x' of converter 1 is converted to absolute value x" by absolute quantity changing equipment 3, and absolute value x" is given to moving average value calculating unit 4 to calculate the moving average value, and output value (y) is obtained. In this case, data are rearranged to such positional relation that the numger of data x" used in unit 4 may correspond to one-period components of x" equivalently and x" may be equivalent relatively. The sampling period of unit 2 and the number of data used in unit 4 are so set that position relations of all data may be different from one another and position relations on the phase between respective data may be equal to one another under this state. As a result, the data volume used for average value calculation is increased practically, and the ripple component rate of output (y) is reduced.

Abstract: PURPOSE:To obtain information which is not registered in advance at low cost at the request of a user individual by receiving the information by a receiving means through a pager calling radio wave. CONSTITUTION:The information, complying with the request made by the user itself, which is sent from a radio base station 4 is received by the pager receiver 13 of the information reception device 6 for the automobile, and stored and held in a memory 14. When a navigation device 5 is powered ON at this time, the received information is transferred to the device 5 and automatically displayed. When the information is not received, the information corresponding to a user's request to display the information from the device 5 is transferred to the device 5 and displayed at the request made by the user 2 as long as the information is present in the memory 14. Thus, the information is received with the paging radio wave, so the cost is reducible and the demands of user individuals can be answered.

Abstract: PURPOSE:To perform effective partial plating of a necessary part without deforming a protruded part, by forming a back holding plate so that only a part corresponding to a protruding part viewed from the side of the back holding plate is made soft and the other part has hardness required for sealing action. CONSTITUTION:In a back holding plate 40, a hard rubber plate 44, in which a through hole having a specified size is provided at the center, is attached to a substrate 42.

Title: Latch circuit
Inventor: GOI YOSHIYUKI
IPC: G11C11/417
Filed: 1992-05-19
Abstract: PURPOSE:To prevent a circuit, which latches the potential at a circuit contact performing dynamic operation by a precharge system, from malfunctioning. CONSTITUTION:The circuit which latches the potential at the circuit node 104 precharged by a 1st precharging means 100 and discharged by a discharging means 110 is provided with a potential detection part 130 which detects the potential of an external output 125 being discharged and holds a latch control line 121 at L. When an enable line 131 is at L, a latch control line 121 is also at L and the precharging is performed in this section. When the enable line 131 goes up to H, the latch control line 121 also rises to H since the circuit node 104 is precharged to H, thereby fetching the potential. When the circuit node 104 is discharged, the latch circuit line 121 goes down to L even if the enable line 131 is at H, so the potential fetch ends and is held.

Filed: 1983-07-14
Abstract: PURPOSE:To make the temperature distribution of a heat roll uniform to prevent a copy failure by arranging plural fixing rolls, which have width narrower than maximum form width, in a carrying path. CONSTITUTION:The first pressure roll 14 presses a heat roll 13 from below independently of the size of a form, and a pair of rolls 13 and 14 have width required for fixing of a small-sized form 11.
