Title: Manufacture of saw device
Inventor: TSUNEKAWA AKIO
IPC: H03H3/08
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To prevent an electrode from being destroyed due to electrostatic destruction in the manufacture process of a SAW device. SOLUTION: After electrodes such as IDT electrodes 2 and reflectors 3 are formed on a piezoelectric substrate 6, the characteristic is measured in the state of the substrate 6 and a conductive material 1 is used to cover at least one electrode or over not in connection state electrically of a surface acoustic wave element 4 being a non-defective component. Then through the process of slittering of each surface acoustic wave element 4, mount of the element onto a package, and electric connection between the surface acoustic wave element 4 and the package, the conductive material 1 is removed and the element 4 is sealed. Since charges due to pyroelectric effect are discharged through the conductive material 1 by this method, electrostatic destruction of the electrodes is prevented.

Title: Error diffusion circuit
Inventor: MATSUNAGA SEIJI
IPC: G09G3/28
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of image quality by eliminating diffusion of error of a signal which is not a video component. SOLUTION: This circuit provided with adding parts 14, 16, an error volume operation part 20, delayers 22, 24, 34 and counters 26, 32, 36 to diffuse a video signal of an original pixel by adding a reproducing error of peripheral pixels is provided with a final dot detecting part 40, a diffusing directing control part 44. A diffusing processing to add the reproduction error of the peripheral pixels including the pixel at inclined upper right direction is performed when the video signal of the original pixel is not the one of the final dot of each line on a display screen and the reproduction error to be added for the diffusing processing is switched to the reproduction error of the peripheral pixels in which the pixel at inclined upper right direction is not included when the video signal of the original pixel is the one of the last dot of each line.  Since the diffusing processing is not performed by generating the reproduction error from the signal which is not the video signal when the diffusing processing is performed to the video signal of the final dot, the degradation of the image quality is prevented. Also, the circuit can be utilized in the case of providing a first line detecting part in place of the final line detecting part 40.

The foreign matter is preferably detected when both synthesized electric signals are compared.  When the magnifying powers of lenses 21a-21d are properly decreased, only the foreign matter affecting an exposure can be detected.

Abstract: PURPOSE:To extrude and cover an electric cable without baking bridging resin on the wall face of a die land section by opening the outlet of a resin passage extruding semiconducting resin at the inlet of the die land section. CONSTITUTION:The outlet 10A of the third resin passage 10 extruding semiconducting resin 12 is provided at the inlet of a die land section 6A. No bridging resin 8 flows on the wall face of the die land section 6A, thus no bridging resin 8 is baked on the wall face of the die land section 6A. Semiconducting resin 12 invariably flows on the wall face of the die land section 6A, semiconducting resin 12 has the bridging reaction speed slower than that of bridging resin and is not baked on the wall face of the die land section 6A. An electric cable with good electric performance can be easily produced without baking bridging resin 8.

Title: Temperature control device
Inventor: IGARASHI TOICHI
IPC: H05B3/00
Filed: 1994-02-21
Abstract: PURPOSE:To obtain a temperature control device which can easily discriminate whether a temperature fuse is melted due to a temperature rise of the thermal fuse beyond its specified value or by any reason other than such temperature rise and which can easily investigate the cause of such thermal fuse cut. CONSTITUTION:A resistor is turned integrally with a thermal fuse 1 by means of an aluminum tape and provided into contact with the thermal fuse 1. A discoloring mark 10 which discolors at a melting temperature of 96 deg.C is printed on the temperature fuse 1. When a heater is heated and overheated, the resistor generates heat and the temperature fuse 1 is melted when its temperature reaches, for example 96 deg.C. When the temperature of the thermal fuse 1 reaches 96 deg.C, the discoloring mark 10 discolors, therefore, the melting due to heating can be easily discriminated. Even if the temperature of the thermal fuse 1 does not rise up to its specified value or more due to a failure of the thermal fuse 1 itself or due to overcurrent, the discoloring mark 10 does not discolor when the thermal fuse 1 has blown, therefore, the cause of such thermal fuse 1 cut can be easily discriminated.

IPC: E01C11/26
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To sharply reduce a using quantity and a cost of heating rope-like bodies, facilitate burying work, and restrain electric power consumption by laying the heating rope-like bodies in passing zones on a road surface where passing of automobile or the like is supposed, and heating the passing zones by its heating rope-like bodies. SOLUTION: In respective traffic lanes 3a and 3a on both sides of a center line 4 of an asphalt pavement, straight line-shaped heating rope-like bodies A are laid in parallel along respective passing zones 5 by holding mutually necessary intervals in the respective passing zones 5 where passing of an automobile or the like of a road surface 3' is supposed. These passing zones 5 are, for example, a locus when a tire of an automobile or the like rollingly contacts with the road surface 3'. A power source is also connected to the heating rope- like bodies A buried in the asphalt pavement. Therefore, since the heating rope-like bodies are laid only in the passing zones where passing of an automobile is supposed, the area of a road surface to be heated is reduced, and the total length of the heating rope-like bodies necessary for heating can be extremely shortened.
