Title: Surface acoustic wave element
Inventor: YAMAJI NOBUKI
IPC: H03H9/145
Filed: 1982-05-06
Abstract: PURPOSE:To suppress the edge effect effectively and to improve the performance, by forming a staircase for both sides of electrodes located at the propagation path of a piezoelectric substrate. CONSTITUTION:Input and output electrodes 2, 3 forming a transducer are formed at a prescribed interval in the major plane lengthwise direction of the piezoelectric substrate 1. The electrodes 2, 3 consist of reed screen electrodes in which plural electrode fingers are meshed with each other. The staircase 6 tapered unidirectionally is formed at the electrode finger 5 at both sides crossed to the propagation path of the piezoelectric substrate 1 in the electrodes 2, 3. Through the provision of the staircase 6, signals reflected at side ridges of the electrode finger are cancelled with each other and the edge effect is suppressed. Thus, the edge effect is suppressed effectively and the performance is improved.

Abstract: PURPOSE:To prevent a connection resin squeezed out on the periphery of a semiconductor chip from curing by using a mask at the time of light irradiation on the resin. CONSTITUTION:A mask provided with such a shielding part that light to be irradiated afterward is not irradiated on a connection resin 3 squeezed out on the periphery of a first semiconductor chip 4 is installed on the surface, whereon the chip is not installed, of a wiring board 1. After that, ultraviolet light 8, for example, is irradiated to cure the resin 3 of the chip 4, to fix the chip 4 on the board 1 and at the same time, to connect electrically bump electrodes 5 of the chip 4 with conductor wirings 2. At this time, the resin 3 squeezed out on the periphery of the chip, 4 is not cured because the light is shielded by the mask 7.

Title: Thermal copying device
Inventor: YOSHIKAWA MASANORI
IPC: G03B27/26
Filed: 1986-04-01
Abstract: PURPOSE:To obtain a good printing being free from an uneven density by eliminating a temperature gradient of a glass plate and applying a uniform temperature bias to thermosensible ink, by providing a cooling air course in which a pressure contacting transparent member constitutes a part thereof, and a cooling fan, and rotating forward and backward the cooling fan periodically. CONSTITUTION:An air course is formed by placing adjacently a reflecting mirror 4 and a glass plate 6, and when a cooling fan 7 operates, a cooling air flows along this air course. In such a case, the cooling air flows by absorbing the heat from the glass plate 6, an exposure light source 5 an the reflecting mirror 4, therefore, in an inlet and an outlet of the air course, the temperatures are different. On the glass plate, a temperature gradient is generated in the direction of the cooling air, but by rotating forward and backward the cooling fan 7 periodically, the direction of a flow of the cooling air is inverted, and the temperature gradient of the glass plate is offset. In such a way, a good printing being free from an uneven density can be obtained by eliminating the temperature gradient of the glass plate, and applying a uniform temperature bias to thermosensible ink.

Abstract: PURPOSE:To improve the input/editing efficiency of documents by designating a copy sender and a copy receiver of the line qualifying information so that the line qualifying information stored in a line qualifying area is copied easily and quickly at an optional row position. CONSTITUTION:A document area including the line qualifying information is supplied to a certain row and this row qualifying information is copied to another row. In this case, a cursor is shifted to the row position where the copy of the row qualification of a display document is desired from a keyboard 5. Then a prescribed key is operated for instruction of the copy of the row qualification. Thus a CPU 1 proceeds to a program for copy of the line qualification and a guidance message is displayed on a CRT 7. As a result, the cursor is shifted to the line position of a copy receiver and an execution key is pushed. Thus the line qualifying information is copied to a line qualifying area corresponding to a document area of the relevant line of an internal memory MMU 2. Thus it is possible to perform quickly the line qualifying copy mutually between optional rows with a simple operation.

Title: Piezoelectric wave transmitter-receiver
Inventor: OGURA KOJI
IPC: H04R1/44
Filed: 1986-03-31
Abstract: PURPOSE:To improve a directional characteristic in a wave transmitter and to improve an S/N in a wave receiver in terms of a device provided with a piezoelectric board comprised by forming electrodes on both surfaces of a piezoelectric flexible sheet by permitting a holding plate to maintain the shape of the piezoelectric flexible sheet so that tension acts on the center. CONSTITUTION:Electrodes 2 and 3 are formed on both surfaces of the piezoelectric rubber sheet 1, which is polarized in its thickness direction by impressing a DC voltage on the electrodes 2 and 3. The piezoelectric rubber sheet 1 is stuck to a curvature holding plate 10 made of plastic metallic materials such as aluminum and stainless steel. A maximum curvature part (x) is formed in the center of the curvature holding plate 10. When the plate 10 is pressed in the vertical direction from its top to deform it flat, the center of the piezoelectric rubber sheet 1 is forcibly extended together with the smoothing of the maximum curvature ratio part (x), and a large tension is applied to the center. Since the shape is maintained so that tension is applied only to the center, it can improve a piezoelectric action and an electro distortion action.
