Title: Surface acoustic wave transducer
Inventor: YASUHARA YOSHIHIKO
IPC: H03H9/145
Filed: 1984-06-26
Abstract: PURPOSE:To eliminate the effect of reflection spurious wave over a wide band by constituting the titled transducer through the combination of an electrode finger pair causing only electric reflection and an electrode finger pair causing electric reflection and acoustic reflection and having different acoustic reflection. CONSTITUTION:A surface acoustic wave transducer is constituted to a surface acoustic wave propagating section of a piezoelectric substrate 11 by crossing the electrode finger pairs 14, 15 of the 1st and 2nd comb-line electrodes 12, 13. Only the electric reflection component is caused to the electrode finger pairs 14, 15 and the acoustic reflection is nearly zeroed in the 1st type electrode 14 and both the reflections are caused in the 2nd type electrode finger pair 15, and they are combined. The width of the electrode fingers 14a, 14b of the electrode finger pair 14 and the electrode fingers 15a, 15b of the electrode finger pair 15 is set nearly to 1/8 of the wavelength of the propagated surface acoustic wave. Further, the electrode fingers 15a, 15b are constituted to have different acoustic reflection. Thus, the reflection spuriousness is reduced over the wide band.

Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To easily grasp the schedules and also the starting time of every schedule by changing the display color of schedule data according to the starting time of the schedule data. SOLUTION: The schedule contents 26 are shown in colors showing the morning, daytime and nighttime respectively from the upper positions, and a bar graph 23 is drawn in colors corresponding to those of the contents 26. A schedule input screen is roughly divided into the processing selection parts 19 to 22, a schedule contents input/output part 26 and a function selection part 27. The time of the graph 23 is varied by instructions of the cursors 24 and 25. Then the display color of schedule data is changed according to the starting time of the schedule data stored in a storage means. Furthermore, a setting means is added to set the time band and color stored in a color storage means. Thus, it's possible to obtain an information processor that can set a color and a time band desired by a user and also can be easily operated.

Abstract: PURPOSE:To obtain a high output fuel cell of small inner resistance by providing a conductive supporting body with a function as connecting tools for electrically connecting plural single cells, which supporting body keeps plural single cells being connected in parallel to each other. CONSTITUTION:Each single cell 1 is held while in contact with the inner peripheral face of the tubular portion 8c of a supporting body 8, and a stack comprises five single cells 1 connected in parallel to each other. In each stack, a plate- shaped portion 8a located on the center side of the single cell 1 is integrated with the tubular portion 8c of adjacent other stack, and also the tubular portion 8c surrounding the single cell 1 is integrated with the plate-shaped portion 8a surrounded by the single cell 1 in the other stack, and so plural stacks are connected in series to each other by putting each plate-shaped portion 8a as one electrode and each tubular portion 8c as the other electrode in conduction to each other sequentially. As a result, the supporting body is used as parts with integrated structure serving also as connecting tools for the group of single cells, and besides the cross area where current are caused to flow is wide so that the inner resistance is reduced and the current passage is shortened. High output is thus achieved.

Abstract: PROBLEM TO BE SOLVED: To obtain a glass forming die without the protective film being released even if glass is repeatedly formed, excellent in durability and suitable to produce an optical lens by a reheat-press process by treating the die in a nitrogen atmosphere and decreasing the nitrogen atom concn. continuously from the die surface toward the inside. SOLUTION: Silicon carbide and sintered hard alloy are optimum as the base material of the die. The die is allowed to stand in the nitrogen atmosphere at 0.7×10<5> -4×10<5> Pa and 1,200-1,800 deg.C for 1-10 hr and heat-treated or treated with the nitrogen plasma of 100-500 W at room temp. to 500 deg.C for 1-5 hr. By such treatment, a part of the outermost surface is converted mainly to silicon nitride when the base material is made of silicon carbide and converted to tungsten nitride when the base material is formed with sintered hard alloy. Consequently, a die capable of being easily released even from glass is obtained.

Filed: 1990-05-22
Abstract: PURPOSE: To eliminate the bending and vibration of filaments and the falling of carbonate when arranging the filaments, by making many filaments handleable in a pulled condition and at a stroke. CONSTITUTION: Filaments 2 are arrayed in a condition where they are pulled to a given position of the upper surface of a frame 1, and successively both supporting bodies 3 are positioned onto both welding areas 5; after that one end part of the supporting bodies 3 is deposited by a normal spot welding method. Next, when the other end part of the supporting bodies 3 is fixedly attached onto a base board B, the frame 1 doubles as the role of a jig for supporting both the supporting bodies 3 until they are fixed to the base board B to maintain the pulled condition of the filaments 2. Then in the frame 1, all parts, except the welding areas 5 joined with one end part of the supporting bodies 3, are removed in order along a cutting line 4; as a result, the many filaments 2 can be handled at a stroke in a condition where they are pulled.  This eliminates bending or vibration in arranging the filaments, and moreover quality deterioration such as brightness lowering because of no cause for inducing the falling of carbonate in working.

Filed: 1995-05-31
Abstract: PURPOSE: To cool a circuit board uniformly and efficiently by providing an auxiliary pipe having larger cross-section than a cooling pipe thereby sustaining a substantially constant flow rate of cooling water for respective cooling pipes. CONSTITUTION: A cooling water supply pipe 13 and a cooling water return pipe 14 are disposed, respectively, on the outer and inner circumferential sides of a board containing section 7 and a plurality of cooling pipes 16 are coupled, at one ends thereof, with the cooling pipe 13 and, at the other ends thereof, with the cooling pipe 14.

Cross-section of the auxiliary pipe 19 is set larger than that of the cooling pipe 16. The cooling pipe 16 is secured with a cooling plate. Heat generated from an IC 20 mounted on the board 10 is transmitted to the cooling plate which is cooled by cooling water 15 flowing through the cooling pipe 16 in order to discharge the heat to the outside.  Since the auxiliary pipe 19 has larger cross-section than the cooling pipe 16, flow rate of the cooling water 15 can be sustained substantially constant for respective cooling pipes 16 and all ICs 20 on the board 10 can be cooled uniformly.
