Title: Surface acoustic wave convolver
Inventor: MOCHIZUKI NORIHIRO
IPC: H03H9/72
Filed: 1988-05-19
Abstract: PURPOSE:To improve a characteristic by suppressing self convolution by providing at least one auxiliary electrode with different length in a direction of propagation between areas where a surface acoustic wave is propagated through first and second central electrodes, respectively. CONSTITUTION:The central electrodes 3a and 3b are formed on a piezoelectric substrate 1 along a direction where the surface acoustic wave radiated from an interdigital electrode 2 is propagated in parallel and adjacently with each other. Also, the auxiliary electrodes 4a and 4b are formed between the interdigital electrode 2 and the central electrodes 3a and 3b. And, for example, the area B of the auxiliary electrode 4a corresponding to the central electrode 3b is formed larger by DELTAl in the direction of propagation than the area A corresponding to the central electrode 3a. By covering the surface of the piezoelectric substrate 1 with a conductor of lithium niobate. etc., the speed of the surface acoustic wave is decreased compared with that of a free surface. And it is possible to shift the phase of the surface acoustic wave passing the areas A and B, respectively at, for example, 180 deg. by setting the difference DELTAl of the length at an appropriate level.

Title: Measuring method of foam structure
Inventor: AYUTA KOICHI
IPC: G01N33/38
Filed: 1989-05-15
Abstract: PURPOSE:To measure a foam structure precisely in a short time by applying a light onto the surface of a sample having foam in the surface from a plurality of directions, from one direction after another, by picking up an image each direction and by measuring the foam from a difference in brightness in the same position. CONSTITUTION:A light is applied onto the surface of a sample, e.g. set concrete, having foam in the surface from a plurality of directions, from one direction after another, and an image in each direction of application is picked up. The brightness of reflection thereof is different since a foam part has a shape of depression from the surface of the sample. In the foam part, the level of the brightness is different even in the same place according to the direction of application of the light, while the brightness in a part other than the foam part has the same level. Based on this difference in the brightness, e.g. a brightness difference, accordingly, a foam structure can be measured precisely in a short time.

Title: Mold for press molding ceramic product
Inventor: AKITANI YUKO
IPC: B28B3/02
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce the machining cost of a mold for press molding by a method wherein chamfering plates are fixed to the edge faces of a main body for chamfering-forming the peripheral edges of a ceramic product such as a roofing tile or the like. SOLUTION: On the edge faces of mold main bodies 21 and 41, a plurality of short pins 11 are protrusively provided, while engaging holes for engaging with the pins are formed on chamfering plates 25-37, 47 and 48. Since the chamfering plates 25-37, 47 and 48 are positioningly fixed to the mold main bodies 21 and 41 by fitting the pins to the engaging holes, the number of threaded holes can be reduced as compared with the conventional mold, in which the chamfering plates 25-37, 47 and 48 are fixed solely with countersunk screws 16. The machining time of a mold can be shortened as compared with that of the conventional mold, in which the threading work requires time, resulting in sharp reduction of the machining cost of the mold.
