Title: Surface acoustic wave filter device
Inventor: YAMANOUCHI KAZUHIKO
IPC: H03H9/64
Filed: 1993-03-30
Abstract: PURPOSE:To provide a surface acoustic wave filter device superior in side lobe characteristic and satisfactory in phase characteristic and noise level. CONSTITUTION:Plural filter stages are formed on a piezoelectric substrate 1, and each converter which comprises each filter stage is arranged so that the propagation lines L1, L2 of the surface acoustic wave of each filter stage can be set in parallel with each other and also, the propagating direction of the surface acoustic wave can coincide with each other. Also, a reception side converter 3 at the front stage and a transmission side converter 3 at the rear stage are arranged on an axial line intersecting orthogonally to the propagating axial line of the surface acoustic wave. Long distance between a transmission side converter 2 at the front stage and a reception side converter 5 at the rear stage can be set by employing such arranging type, which sufficiently prevents electromagnetic coupling between neighboring filter stages from occurring. As a result, it is possible to provide the surface acoustic wave filter device superior in side lobe characteristic and satisfactory in phase characteristic and low noise level.

IPC: G03F7/00
Filed: 1986-03-29
Abstract: PURPOSE:To make equal the developing speed in the central part of a semiconductor wafer with that in the peripheral parts and to eliminate the dimensional difference of a resist pattern by a method wherein a nozzle which is made to jet a developing soultion on the semiconductor wafer, is rotated. CONSTITUTION:A chuck 12 is maintained in a stopped state without being rotated and while a motor 15 is driven and a nozzle 13 is rotated, a developing solution is jetted on a semiconductor wafer 10 through the nozzle 13. in this case, as the main body 13a of the nozzle bas a length equal or more with the diameter of the semiconductor wafer 10, the developing solution is sprayed on the whole surface of the semiconductor wafer 10 by the rotation of the nozzle 13. As the semiconductor wafer 10 is not rotated during the developing, no centrifugal force does not act on the developing solution and the developing solution pervades uniformly the whole surface of the semiconductor wafer 10. Accordingly, there is no dlfference between the amounts of the developing solution in the central part and peripheral parts of the semiconductor wafer 10 and the dimensions of a resist pattern in the central part and peripheral parts become uniform.

Title: Semiconductor memory
Inventor: FUJIMOTO TOMONORI
IPC: G06F15/78
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory having novel refresh input specifications, thereby lessening a burden on a logic circuit for controlling accessing by the memory. SOLUTION: A part from a pulse train of refresh requirement signals (RRQ) requiring a refresh operation for each row of a memory, a self refresh mode (SRMOD) signal is fed to a refresh control circuit. When the SRMOD signal shifts from 'L' to 'H', an oscillation circuit 10 immediately starts the generation of a clock pulse train. A set pulse is generated in response to the clock pulse train, which sets a flip flop circuit 30. As a result, a front edge of the pulse of a periodic refresh requirement (PRRQ) signal is generated. Every time the PRRQ signal becomes an 'H' level, a reset pulse is generated, which resets the flip flop circuit 30, and a rear edge of the pulse of the PRRQ signal is generated.

Title: Improving method for train shunting sensitivity of track circuit
Inventor: KANARI SHOHEI
IPC: B23K35/30
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To improve the train shunting sensitivity of a track circuit by causing spark discharge between a consumable electrode and the surface of the head of a rail having rust on the surface, thereby removing rust. SOLUTION: A consumable electrode is taken as an anode, the surface of the head of a rail having rust on the surface is taken as a cathode, and voltage is applied between them to cause spark discharge, thereby removing rust on the surface of the head of the rail. Subsequently, instead of the above, a consumable electrode formed by a conductive high corrosion resistance material is used to form a spark discharge building up layer on the surface of the head of a rail. Subsequently, when a high nickel-base Hastelloy having high corrosion resistance and high wear resistance is used in the anode, the subsequent generation of rust can be surely prevented by once building up, so that the shunting sensitivity can be surely kept even in a line with a low train passing frequency.  Thus, the work efficiency can be remarkably improved as compared with the conventional method, and the manhour for maintenance for the rail can be reduced.

Title: Sawtooth wave generator provided with disturbing signal eliminating function for deflection device
Inventor: WILBER JAMES ALBERT
IPC: H04N3/16
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide the sawtooth wave generator for a deflector in which modulation of a ramp start voltage due to a disturbing signal component is prevented. SOLUTION: An end time of a retrace part of a vertical sawtooth wave signal of a vertical sawtooth wave generator 18 is controlled by an output signal 112a of a comparator 19. The comparator has an inverting input terminal responding to a reference voltage (VLOW) and a noninverting input terminal responding to the sawtooth wave signal. The reference voltage is coupled with an input terminal (base of a transistor (TR) Q7) of amplifiers (Q5, Q6, Q7, Q8) of an integration device generating the sawtooth wave signal. A disturbing signal component in a reference signal is superimposed on the sawtooth wave signal. Since the same disturbing signal component is generated simultaneously for both input terminals of the comparator, a common mode signal is eliminated from the disturbing signal component with high accuracy.
