Title: Detecting devie for dew condensation-frosting
Inventor: TOYODA MINORU
IPC: G01N29/00
Filed: 1981-04-06
Abstract: PURPOSE:To enable detection of the state of dew condensation or that of frosting by one element, by using as a sensor an elastic surfce wave element operating by a method of separate excitation or self-excitation. CONSTITUTION:A power source 3 is connected to the input transducer electrode 2 of an elastic surface wave element 1, while an output transducer 4 is provided opposite to the electrode 2. When the elastic surface wave element 1 thus formed and operating by a method of separate excitation is used as a sensor, the change in frequency and the change in an output level are caused by the state of dew condensation or the state of frosting. Accordingly, by reading these changes, the state of dew condensation and that of frosting can be detected. That is, the dew condensation or frosting can be discriminated by giving an output of the sensor 9 to each of comparators 11 and 12. In this way, the state of dew condensation and that of frosting can be detected by one element. A device of a self-excitation method can also be employed in the same way.

Title: Paper feeding device
Inventor: TODA TAKASHI
IPC: B65H3/56
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To convey papers at a constant speed in a simple structure, even though with different sizes. SOLUTION: When a width setting plate 34 is abutted to both ends in the width direction of papers Q, the abutting part 66 of a link 60 rides on a projection, the link 60 is rotated clockwise, and its engaging piece 72 is engaged to the gear 52 of a brake disk 50. The rotation of the brake disk 50 is stopped, and a paper feeding roll couple 42 fixed to the brake disk 50 are not rotated. By the rotation of a paper feeding roll shaft 40, the other paper feeding roll couple installed to the inner side of the paper feeding roller couple 42 are rotated, so as to feed the uppermost paper Q1. The paper feeding roll couple 42 are rotated and don't squeeze the paper Q1 from the upper side, and the paper Q1 generates a loop.  When wider papers are used, the paper feeding roll couple 42 are rotated, but since the diameters of the paper feeding roll couple 42 and the inner side paper feeding roll couple are the same, the conveying speed of the papers becomes constant.

Title: Amplification type solid state image sensor
Inventor: KUDO HIROAKI
IPC: H04N5/335
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To discharge signal charge in resetting even if a pixel size is reduced by enhancing a pixel density. SOLUTION: Each p type field absorbing layer 11 is disposed adjacent to a drain 28 of a MOS transistor 25. When a light (h) is incident through a first gate electrode 29, electron-hole pair is generated by photoelectric conversion, and electrons are fed to the drain 28. The holes are confined by barrier formed at an intermediate of an n type semiconductor well layer 33 and barrier under the electrode 29, stored in a semiconductor-insulating film interface of the layer 33 to become signal charge. A potential of the layer 33 is changed in response to an amount of the charge. The change of the potential is read as a potential change of a source 27. At the time of resetting, potential barrier under an electrode 26 is drawn down, and the charge is discharged to a p type semiconductor substrate 31 via a path shown by a broken line.
