Title: Rear structure of clock
Inventor: KOBAYASHI KAZUHIRO
IPC: G04B27/00
Filed: 2000-07-28
Abstract: PROBLEM TO BE SOLVED: To propose rear structure of a clock for solving reset return failure by returning a bolt to the normal position at all times. SOLUTION: When a winding system 1 is pulled as shown in Fig. (b), a mandarin duck part 2 is rotated around a mandarin duck axis 5 due to the engagement between a groove 1a of the winding system and a tip 2a of the mandarin duck part, and a tip 2c of the mandarin duck slides on the side surface of a bolt 3, thus spreading the bolt 3. In this case, a bolt spring part 3a is engaged with a newly provided mandarin duck escape 2b, thus absorbing the deflection force of the bolt spring part 3a by the escape part, and hence inhibiting the increase in deflection due to the pulling of the winding system 1, so that increasing initial deflection is increased and hence the force for canceling reset when pushing in the winding system is increased and thus eliminating reset return failure.

Title: Image maker
Inventor: KOWADA TAKESHI
IPC: H04N1/387
Filed: 2000-08-02
Abstract: PROBLEM TO BE SOLVED: To save toner by applying mask treatment to the pixels of image data, under the condition in which deterioration of image quality scarcely occurs. SOLUTION: Since image-processing speed is higher, the smaller number of picture elements of image data, when giving image processing speed priority over image quality, density-doubling processing is performed ('YES' in S1). In the relation between the number (n) of pixels of the image data inputted into a printing image controller and the number of pixels of printable resolution within the rotation allowable range of a light source rotating motor, the density doubling interpolation is performed for both the main scanning and subscanning (S2). When density doubling interpolation is conducted, toner saving is performed with an optional toner saving mask pattern (S3).  When the density doubling interpolation ('NO' is S1) is not conducted, since the density of the pixels of the printing data and the density of the pixels for imaging are the same and through the interference between the image data and the mask pattern, image data vanishing possibility exists, so that toner saving is not conducted.

Title: Semiconductor device and guard ring layout method to optimize latch-up preventing effect
Inventor: FUKAZAWA HIDEKI
IPC: H01L27/04
Filed: 2000-08-03
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device as well as its layout method where the performance (amplification factor) of a parasitic element is halved than before by optimizing the layout method for a guard ring. SOLUTION: The activation/deactivation of a parasitic element is intentionally controlled by 'concentrating', 'excluding', 'selecting' VSS substrate contact. Since the parasitic element is activated at a part where the VSS substrate contact is 'concentrated', an excessive current is sucked up by inserting an epi-contract/well-contact into the part. The substrate contact is 'excluded' as possible in a circuit region where the parasitic element is wanted to be deactivated. These regions are intentionally 'selected' on an actual chip. By multiplexing a guard ring, the effect will be two to three times.

Abstract: PROBLEM TO BE SOLVED: To seal and unseal the opening section of a bag body extending to a plurality of times. SOLUTION: At the opening section 2 of the bag body, a corrugated sheet section 14 which is folded into a corrugated state is provided. The corrugated sheet section 14 is equipped with two or more adhesive surfaces 15A to 15D and a surface 18 to be adhered, and folded into the corrugated state in such a manner that the adhesive surfaces 15A to 15D and the surface 18 may be confronted with each other. In this case, the adhesive surfaces 15A to 15D are equipped with an adhesive layer 16 and a release paper 17 which is separably pasted to the adhesive layer 16. Then, the opening section 2 is sealed by pasting the adhesive surface 15A away from the opening section 2 to the bag body. In the meantime, after cutting the adhesive surface 15A, the adhesive surface 15B on the opening section 2 side is pasted to the bag body, and thus, the opening section 2 is sealed twice or more. This sealing structure is applied to an envelope 1, and a receiver display section 26 equipped with a removable sheet (second sheet 30) is provided on the front surface of the envelope. First address and name are listed on a surface (the front surface of a first sheet 27), which is confronted with the rear surface of the removable sheet. At the same time, second address and name are listed on the removable sheet, and the display for the receiver is made changeable by peeling the removable sheet.

Title: Optical modulator
Inventor: KISHI NOBUHITO
IPC: G02F1/035
Filed: 2000-08-07
Abstract: PROBLEM TO BE SOLVED: To provide an optical modulator improved in DC drift characteristics. SOLUTION: The optical modulator is provided with an x-plate LiNbO3 substrate 11 in which an optical waveguide 12 is formed, an electrode substrate 15 in which an electrode 14 is formed and a spacer material 17 and an adhesive 13 separating the x-plate LiNbO3 substrate 11 and the electrode substrate 15. The fluctuation of a DC electric field of the optical waveguide 12 can be prevented, since there is a hollow part 16 between the x-plate LiNbO3 substrate 11 and the electrode substrate 15 and concentration of electric charges caused by applying direct voltage is not occurred in the hollow part 16. And since heat is hardly connected through the hollow part 16, heat of the electrode 14 is hardly conducted to the optical waveguide 12 and the generation of unnecessary electric charges in the x-plate LiNbO3 substrate 11 can be prevented.  Thus, the DC drift can be prevented and the optical modulator improved in DC drift characteristics can be obtained.

Title: Reduction-resistant thermistor element, its manufacturing method, and temperature sensor
Inventor: OGATA IPPEI
IPC: G01K7/22
Filed: 2000-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain a high-accuracy reduction-resistant thermistor element having a superior resistance stability that its resistance does not change much even when the thermistor is exposed to a reducing atmosphere. SOLUTION: The thermistor element has such a structure that an oxygen storing and releasing composition, such as CeO2, is dispersed in a composition composed mainly of an (M1M2)O3AOx mixed sintered compact. Since the movement of oxygen from the composition constituting the element is suppressed by releasing oxygen from the composition in the reducing atmosphere, the resistance of the thermistor does not change much even when the thermistor is exposed to the atmosphere. Therefore, the thermistor can detect temperatures with accuracy over a long period and a highly reliable temperature sensor can be realized by using the thermistor.
