Title: Transfer paper container for copying machine
Inventor: KANZAKI MICHIO
IPC: B65H31/20
Filed: 1980-03-13
Abstract: PURPOSE: To prevent the crook of the tansfer paper due to buckling even if the size of the paper becomes large by controlling the height of the tray member of the paper discharging tray, on the discharge roller side, according to the weight or quantity of the transfer paper.  
     CONSTITUTION: Transfer paper 3 of A 4  size is discharged from discharge rollers 1 onto a paper discharging tray 2 and successively stacked up on one tray member 2a, which sinks by a bending allowance δ, because compression springs 5 supporting the contained transfer paper 3 bend with the weight thereof. However, because the height of the uppermost portion of the transfer paper 3 is within the stack limits L, there is no possibility of buckling of the tranfer paper 3. Even when the size of the transfer paper changes, the compression springs 5 bend according thereto so as to maintain the height of the uppermost portion of the transfer paper 3 within the stack limits L.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a highly accurate excitation light incident surface by sticking an annular seal material to one surface of a glass plate and filling its center space with a material identical to a gel electrolyte layer forming material. SOLUTION: For sticking a glass plate 1 serving as an excitation light incident window to a migration plate, a sealing material 3 is used. The inside of a space 7 of this sealing material 3 is filled with a gel electrolyte identical to a gel electrolyte layer forming material. Thereby, a laser light passed through the glass plate 1 is not irregularly refracted and made incident on the gel electrolyte layer of the migration plate. Since the sealing material 3 absorbs ruggedness caused by the machining errors of the migration plate and a glass plate end surface, preferably, it is made of a flexible elastic material such as sponge. Also, a groove 9 communicated with the space 7 is provided in the upper end of the sealing material 3, and this groove 9 is used as an air vent hole for supplying gel solution into the space 7.  Adhesives are coated on both surfaces of the sealing material 3, and the glass plate 1 is stuck to its one surface while back paper 5 is stuck to the other surface. Then, the back paper 5 is peeled off after the hardening of the supplied gel electrolyte solution and stuck to the end surface of the migration plate.

Title: Angular speed sensor
Inventor: SHIRATORI NORIHIKO
IPC: G01C19/56
Filed: 1995-01-27
Abstract: PURPOSE: To reduce the size while enhancing the sensitivity by pasting piezoelectric elements, provided with electrodes, to the opposite sides of an oscillation substrate, disposing a detection electrode also serving as an exciting electrode (feedback electrode) on the upper surface and an electrode facing the exciting electrode on the lower surface, and disposing a weight at the sensor part. CONSTITUTION: Detection electrodes 6-9 having lead-out electrodes 6a-9a, also serving as exciting electrodes, are formed on the upper surface of a piezoelectric ceramic disc 1 having the lower surface formed with an electrode having diameter larger than that of the outer circumferential circle of the detection electrodes 6-9. A connection electrode 4 is formed between the electrode on the lower surface and the upper surface of the piezoelectric ceramic disc 1. Since the electrode on the lower surface is connected electrically with the oscillation substrate and bonded thereto, the disc 1 oscillates upon application of an AC voltage between the substrate 2 and the electrodes 6-9 thus causing oscillation of the substrate 2. When the angular speed sensor senses an angular speed, Coriolis force is generated in the weight at the sensor section and the piezoelectric element in the angular speed sensor is deformed. Consequently, the voltages at the electrodes 6-9 are varied and the angular speed can be detected on the X-axis and Y-axis.

Title: Color filter
Inventor: EDA KOURAI
IPC: G02B5/20
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To relieve positional accuracy and to make it possible to form color filters having fine patterns by patterning the peripheral parts of adjacent filter layers so as to overlap these parts on each other with light shielding layers and flattening the build-ups of the overlap parts by polishing. SOLUTION: Black matrices 2 which are the light shielding layers are pattern formed on a substrate 1 and, thereafter, the filter layer 3R of the first color is pattern formed. Next, the filter layer 3G is patterned in such a manner that the pixel ends thereof overlap on the pixel ends of the filter layer 3R. Similarly, the filter layer 3B is patterned as well. The overlap parts 3A are thereafter removed by the polishing treatment to flatten the surface of the filter layers 3. Consequently, the difference in level of the intra-surface film thickness is confined within 0.5μm. Transparent electrodes (ITO) are sputtered directly on the color filters after the stages described above. In such a case, the film deposition condition of the transparent electrodes is good.
