Title: Fluorescent tube
Inventor: HIRASHIMA YASUHITO
IPC: H01J61/35
Filed: 1989-07-11
Abstract: PURPOSE:To carry out shading correction with a dynamic range of uniform image signals in the whole surface of an original document by forming a not coated part only int he peripheries in both ends in the longitudinal direction of a glass tube. CONSTITUTION:A fluorescent tube 1 is used as a light source 6 of a image reading apparatus, a fluorescent material 4 or a reflecting material 3 is applied to the inside of a glass tube 2 of the fluorescent tube 1, and a not coated part 5 is formed only in the peripheries in both ends in the longitudinal direction of the glass tube. In the case that the open part 5 not coated with the fluorescent material or the reflecting material faces to an original document, the illuminance of the original document becomes high as compared to the case that the open part 5 does not face to the original document. In this way, without mechanical shading correction, shading correction is carried out and the image signals of a line image sensor 9 become almost uniform.

Patent JP-H0469407-A (JP)
Title: Power driving gear
Inventor: TAKEKOSHI TARO
IPC: F16H55/17
Filed: 1990-07-06
Abstract: PURPOSE:To obtain strong connecting force by forming fine ribs with an external diameter larger than the center hole diameter of a driven body in an area of inserting a drive shaft into the driven body by pressure, and forming a material in a center hole part of the driven body weaker than a material of the drive shaft. CONSTITUTION:Since an outermost diameter d2 is larger than a center hole diameter D of a driven body 2 in a rib 1-a formed on a drive shaft 1, the rib 1a bites in a center hole 2-a of the driven body 2 formed of weak material as compared with the drive shaft 1, and its rib 1-a is surrounded with the hole 2-a fine elastically plastic-deformed. Accordingly, strong connection can be obtained in the direction of rotation. Since an area of the rib 1-a is limited partly to an insertion area between the drive shaft 1 and the driven body 2 by decreasing a length 2 of the rib 1-a shorter than a length L of the center hole of the driven body 2, loose-stop force in the axial direction is also improved by forming a degree stop with the hole 2-a by an axial directional end face 1-b of the rib 1-a. Further, these effects of action are strong against also a change of temperature since the plastic deformation of shape is utilized therein.
Patent JP-H0230023-A (JP)
Title: Pushbutton switch
Inventor: KATO KIMIFUMI
IPC: H01H13/12
Filed: 1988-07-20
Abstract: PURPOSE:To make the form of a pushbutton switch thinner by providing a contact construction wherein turning movement of a lever moves a movable contact so as to interrupt the contact. CONSTITUTION:A key top 23 is pressed against the spring force of a coil spring 35 so as to be displaced thereunder, then the spring force of the coil spring 35 gradually increases to increase reaction force acted upon the key top 23. And this spring force is transferred from the coil spring receiving protrusion 27 of the lever 30 to the dome-shaped portion 39 of a reversal spring 37 via an abutting portion 36. When this spring force becomes greater than the automorphic resilience of the reversal spring 37, the dome-shaped portion 39 is reversely displaced at its center portion in such a manner as to be bended in the direction of the inner bottom face of a main body 21 i.e., upwardly. The lever 30 is thereby put in clockwise rotation about a shaft portion 33 for rapidly extending the coil spring 35, so that operating force of the key top 23 decreases. There will hence be no need for a pressing element to be interposed between the coil spring and the reversal spring, as is done by conventional methods, and also the disposition of the coil spring 37 enables the overall height of a pushbutton switch to be reduced.

Title: Solid-state image pick-up device
Inventor: NOZAKI HIDETOSHI
IPC: H04N5/335
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To increase the collecting efficiency of signal electric charge and to improve sensitivity, by forming a high concentration impurity region and a low concentration region in a semiconductor substrate having the reverse conducting type from the signal electric charge, and decreasing the concentration of impurities toward the surface of the substrate. SOLUTION: A concentration profile is formed so that the impurity concentration in a P-type semiconductor substrate becomes higher in the deep direction from the surface of a diode. Thus, the concentration gradient is formed in the low impurity concentration region, and the signal electrons generated in this concentration gradient can be collected in a photodiode. Therefore, the optical sensitivity for visible light is increased. Furthermore, when the high luminance light is inputted, the signal output is logarithmically attenuated when the output is removed from the incident region. Therefore, the blooming phenomenon effected by the lateral diffusion of the signal electric charge can be suppressed.

Title: Transmission controller of vehicle
Inventor: SAITO KATSUO
IPC: B60H1/08
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To sufficiently ensure the heating capability by correcting the change gear ratio low in the operation with an engine cooling water temperature lower than a low gear water temperature level when a high heating capability is required. SOLUTION: A CVT control unit 41 judges an operating state requiring high heating capability, and corrects the target change gear ratio of a continuously variable transmission to be low so that the operating state with an engine water temperature TW lower than a low gear water temperature level is provided when the high heating capability is required. The judgment of the operating state requiring high heating capability is performed by judging the cooling water temperature drop, outside air temperature drop, or rise of fan air quantity of a heater fan at the time of engine start. When it is judged to require the high heating capability, the change gear ratio is corrected low to promote warming by increasing the number of rotation and the heating amount of the engine, and after the engine is warmed, and the heating capability within the cabin is sufficiently ensured.  Thus, the heating value of the engine is increased according to the increase in required heating capability, and a sufficient heating capability can be ensured.
