Abstract: PURPOSE:To improve ease of processing without losing the electric characteristic by forming four corners of cross section of a chamferred waveguide in the form of circular arc and designing each dimension so that the cut-off wavelength and the characteristic impedance are made equal to those of a conventional rectangular waveguide. CONSTITUTION:The cut-off wavelength lambdac2 of the waveguide is expressed as lambdac2=2a2[1-K(r/a2)<2>] by the perturbation method, where the lambdac2 is supposed to be sufficiently smaller in comparison with a long side a2, b2 is the size of a short side and (r) is a radius of the circular arc at four corners in the cross section of the waveguide. The establishment of the relation of 2a1=2a2[1-K (r/a2)<2>] is the necessary and sufficient condition in order to make the wavelength lambdac2 equal to the cut-off wavelength lambdac1 of the waveguide having the inside long side a1 and short side b1, where K is a value of 1<=K<=4 practically. The (r) is a half the size of the short side, and the characteristic impedance of both the waveguides is made qual in this case with the relation of b2/a2=b1/a1.

Title: Access device
Inventor: KAWASHIMA OSAMU
IPC: G11B21/08
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To eliminate an error generated in continuous jump movement by correcting the number of tracks to be jumped over so as to make an N-fold arithmetic means and an addition-subtraction arithmetic means contain no error. SOLUTION: When the number of tracks from the head of a program area to a target track 1 and a track positioned in the present address is obtained respectively by a relative tack calculating means 3, and from this result the number of tracks in existence between their tracks is calculated, a constant in the next place is obtained and is multiplied by the number of tracks calculated by the means 3 by the N-fold arithmetic means 7. This constant is a value obtained by dividing an average jump time interval of a continuous jump moving means 6 by a time of one revolution of a disk in a disk position to perform jumping. When the number of tracks calculated by the means 3 is more than a prescribed value, a traverse moving means 5 is started up by an access control means 4, and when the number of tracks is less than the prescribed value, the means 6 is started up.  When the means 6 is started up, a value calculated by the means 7 is added to or subtracted from the number of tracks calculated by the means 3 to correct a pickup in response to its moving direction by the addition-subtraction arithmetic means 8.

Title: Method for pneumatically passing wire through pipe
Inventor: HAYASHIZU YOSHITOSHI
IPC: G02B6/46
Filed: 1993-05-21
Abstract: PURPOSE:To prevent a wire from being caught and stopped in a pipe to smoothly pass it through the pipe and to eliminate a futile wire feed speed reduction time by changing the wire feed speed in accordance with a preliminarily set speed pattern. CONSTITUTION:When an optical transmission wire is pneumatically passed through a pipe 3 having bend parts B, C, D and E on the way, the feed speed of the optical transmission wire is set like (b). That is, the optical transmission wire is fed at the steady speed when its front end passes the straight part, and it is fed at a speed lower than the steady speed when its front end passes bent parts B, C, D and E. Since the feed speed is reduced when the front end of the optical transmission wire passes band parts B, C, D, and E, the front end part of the optical transmission line is not caught in bend parts and the optical transmission wire is smoothly passed, and the overall time required for passing wire is shortened.

Title: Method and device for deciding tile size for wave front type parallel calculation
Inventor: ONO HIROYUKI
IPC: G06F15/177
Filed: 1993-05-20
Abstract: PURPOSE:To improve entire throughput by unnecessitating the redivision of arrangement by fixing a tile size in a divided dimensional direction. CONSTITUTION:The tile size in the divided dimensional direction of arrangement is defined as a fixed value not depending on in-processor calculation time per one element of arrangement, and the tile size in the other direction is decided while depending on the in-processor calculation time per one element of arrangement. Concerning the divided dimensional direction of arrangement, a value 802 rounding up the quotient of division 801 with the number of arrangement elements in the dimensional direction as a dividend and the number of processors as a divisor to an integer is defined as the tile size and concerning the other dimension, a value 813 rounding up or rounding off square root 812 of the quotient of division 811 with the time of data transfer between processors as a dividend and in-processor calculation time per one element of arrangement as a divisor to an integer is defined as the tile size. Therefore, even when over two wave front type loops are arranged or mixed with the other calculation pattern, the redivision of arrangement is unnecessitated.

Title: Thin film resistor
Inventor: SAITO SHINJI
IPC: H01C7/00
Filed: 1988-06-09
Abstract: PURPOSE:To achieve excellent contact by making a thin film resistor composed of a sintered body of fine particles of ruthenium oxide and manganese oxide. CONSTITUTION:A coating composition containing both a compound having ruthenium in its structure and a compound having manganese in its structure is applied to a board and then the coated board is sintered. In addition to the metal-based electroconductive mechanism, the electroconductive mechanism derived from a thermal activation process caused by manganese oxide entering the grain boundary of ruthenium oxide and serving as a barrier or that derived from the tunnel effect contribute to giving a very smell temperature coefficient of resistance to the resistor. Further, selected sintering temperatures allow few particles to grow, whereby the sophisticated structure of a sintered body remains intact. In this way, addition of manganese has the effect of suppressing both growth of particles and gasification of ruthenium, thereby allowing modest variations in resistance value with increasing sintering temperatures. Accordingly, the temperature coefficient of resistance is reduced, which then all excellent contact to be obtained.
