Title: Vibration reducing device for engine
Inventor: UMEMURA KYOICHI
IPC: F16F15/30
Filed: 1986-12-05
Abstract: PURPOSE:To change a resonance point of torsional vibration of an output shaft of an engine, and thereby avoid the resonance, by disengageably mounting a rotating member on the output shaft, and providing an engagement/ disengagement control means for engaging or disengaging the rotating member with respect to the output shaft. CONSTITUTION:A primary flywheel 2 is fixed to one end of a crankshaft 1, and an auxiliary flywheel 3 is axially slidably mounted on the crankshaft 1 in such a manner as to be engaged or disengaged with respect to the primary flywheel 2. An engagement/disengagement control means 5 is provided to generate an engagement or disengagement signal to a solenoid 4, so as to operate the auxiliary flywheel 3. With this arrangement, when an engine speed is higher than a set speed, the auxiliary flywheel 3 is engaged with the primary flywheel 2 to shift a resonance point to an engagement resonance speed, while when the engine speed is lower than the set speed, the auxiliary flywheel 3 is disengaged from the primary flywheel 2 to shift the resonance point to a disengagement resonance speed.

Title: Linear image sensor
Inventor: SATO NAOKI
IPC: H04N5/335
Filed: 1986-12-09
Abstract: PURPOSE:To reduce the lowering of picture quality with the discontinuity of a picture due to the change of picture element pitches in the joint of a chip by forming a structure in which a well region is terminated by shaping the shallow well region in comparatively high concentration to the peripheral section of the well region. CONSTITUTION:A second p well region 8 having surface concentration higher than that of a first p well region and shallow diffusion length in the vertical direction is shaped adjacent to the end section of the first p well region 2 having low surface concentration and deep diffusion length in the vertical direction so that one part is overlapped. Since the p well region 8 has shallow diffusion length in the vertical direction, concentration is hardly diminished in the lateral direction. Consequently, a p-n junction photodiode is formed up to the end section of the p well 8. Accordingly, a distance (a) can be shortened.

Title: Image forming device
Inventor: HAYAKAWA NAOSHI
IPC: G03G15/02
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent the soil on the surface of a contact charge member and to uniformize a charge potential even under the condition where moisture absorbing of the contact charge member is different because of environmental fluctuation by detecting the moisture amount of the contact charge member from the detection signal of a moisture amount measuring device and impressing a charge voltage corresponding to the moisture amount on the contact charge member. SOLUTION: Light A emitted from a first light emitting device DeA irradiating a charge roller 102 shows intensity peak at wavelength of 0.8μm, and in the same way, light B emitted from a second light emitting device DeB irradiating the roller 102 shows the intensity peak at wavelength of 1.45μm. The comparison wavelength band (the light A) hardly possesses sensitivity with respect to the moisture amount of the roller 102, the 1.45μm (the light B) possesses large sensitivity as moisture absorbing spectrum. That is, when the moisture amount of the roller 102 is large, the light having the wavelength of 1.45μm is absorbed by the moisture, so that a compared value A/B (the reflected light intensity of the light A/the reflected light intensity of the light B) becomes large. The A/B corresponds to a voltage to be impressed on the roller 102.
