Abstract: PURPOSE:To obtain the leaky wave NRD guide (non-radiative dielectric line) whose band is selected to be wide by providing two discontinuous elements at a specific interval on a dielectric strip and canceling reflected waves generated from the discontinuous elements so as to prevent deterioration in the impedance. CONSTITUTION:The NRD guide has a structure of a dielectric strip 13 inserted between parallel metallic plates 11,12. A 1st discontinuous element 14 is provided to the dielectric strip 13 at an interval of lambdag and 2nd discontinous elements 15,16 are provided to a position apart from the element 14 by an interval of lambdag/4 symmetrical in the vertical direction to each other, where A is a wavelength of a wave propagated in free space. The 1st, 2nd discontinous elements 14-16 are formed by providing a notch to the dielectric strip 13 at an interval of lambdag in general. Thus, the 1st discontinuous element 14 acts like an element emitting a radio wave and the 2nd discontinous elements 15, 16 act like a matching element to cancel a reflected wave from the 1st discontinous element 14 thereby eliminating a return loss.

Title: Golf club head and manufacture thereof
Inventor: SUMITOMO NORIO
IPC: A63B53/06
Filed: 1995-03-27
Abstract: PURPOSE: To facilitate the adjustment of weight by attaching a weight adjusting material to a predetermined spot of a hollow head, which has no fluidity in the room temperature, but has the fluidity to infuse the material into the spot by heating. CONSTITUTION: A head is constituted as a hollow head and a weight adjusting material 2 is attached fixedly to a heel part in the hollow head 1. The weight adjusting material 2 has such fluidity that it is easily infused in the hollow head by heating and loses the fluidity in the room temperature so that it is surely attached fixedly to the interior of the hollow body with adhesion as well as flexibility for use. For example, a thermoplastic material having 50-300 deg.C of fluidity point is used to be infused from an opening 3 and cooled. For example, polyisobutene resin, or the like is used for the thermoplastic resin. Since such material has the flexibility, it is neither cracked to come off, nor produces sounds.

Title: Method and device for table data storage and method and device for table calculation
Inventor: NAKAMURA NORIKO
IPC: G06Q10/10
Filed: 1990-03-20
Abstract: PURPOSE:To shorten the display switching processing time and to economize a storage area by preparing plural data as data to be written in a cell constituting a table. CONSTITUTION:When a floppy disk type (FDD) CRT (70000 yen in the example shown in the figure) is changed to another type CRT (for example, 80000 yen), the display of only this price part is changed from 70000 yen to 800000 yen on an estimate table. Table calculation is executed with respect to the new table after the display change to change the total amount of money also. Consequently, data of only a pertinent part is read out and the display is changed without changing the display of the whole of the table. Thus, data is quickly read out, and the storage area is economized when table data is stored in a storage device.

Abstract: PURPOSE:To speed up correction operation upon drawing by dividing a drawing region into a latticed sub-divisions, approximating each sub-division with a parallelogram, and effecting correction operation for each sub-division with a first-order correction coefficient. CONSTITUTION:An electron beam is deflected in a two-dimensional direction by a deflector 5 and scanned by a predetermined width around a point of deflection. Hereby, reflected electrons from a reference mark on a material 7 are detected by a detector 11 and fed to a control unit 12. The operation is effected at a plurality of locations on the material 7. The control unit 12 evaluates deflection distortion of a drawing region and divides it into a latticed sub-divisions. It further approximates each sub-division with a parallelogram to evaluate the correction coefficient of a first-order deflection distortion. It additionally estimates a first-order correction coefficient for distortion correction and stores it in a correction table 13. Once drawing data is inputted into an arithmetic operation unit 14, the control part 12 accesses a sub-division number corresponding to the inputted drawing data to read out a corresponding first-order correction coefficient and input it into the arithmetic operation unit 14. The arithmetic operation unit 14 estimates a value to be inputted into a DAC amplifier 15 which then drives the deflector 5 for drawing corrected in the deflection distortion.
