Abstract: PROBLEM TO BE SOLVED: To prevent the jamming of an original even when the original is carried to read an image recorded on the original and to prevent the original from being damaged by setting a paper ejection mechanism to either a reversal mode or a non-reversal mode based on the thickness of the original detected by an original thickness detection means. SOLUTION: An original thickness detection sensor detecting the thickness of original is provided between an original existence sensor and an image tip detection sensor. When the thickness of the original detected by the original thickness detection sensor is equal to or under a specified thickness, a reversal flapper 5n is at the position of the non-reversal mode for ejecting the original without reversing it. Meanwhile, when the thickness of the original detected by the original thickness detection sensor exceeds the specified thickness, the flapper 5n is at the position of the reversal mode for ejecting the original after reversing it.  Whether the original is ejected without reversing it(non-reversing state) or it is ejected after reversing it is decided based on the thickness of the original, so that the jamming of the original(original jam) is not caused and the original is not damaged.

Filed: 1991-12-25
Abstract: PURPOSE:To accurately detect that a lead falls off a lead chuck when the lead is ejected from the lead chuck of a pencil by a predetermined amount by an ejecting action and the lead chuck holds the lead at a different position. CONSTITUTION:The pressure contact position of a lead chuck 62 against a chuck guide 42 when the lead chuck 62 holds a lead 54 by a pressing force of a spring 64 is axially shifted from that of the lead chuck 62 when it does not hold the lead 54. Therefore, if the lead falls off the lead chuck 62, a lifting amount of a lifting/lowering pipe 44 when the lifting/lowering pipe 44 is lifted by a predetermined amount from a position where a knob 68 abuts on a pressing plate for releasing the lead chuck 62 is not equal to a lowering amount thereof when the lifting/lowering pipe 44 is lowered from said lifted position for releasing the lead chuck to a position where the pressure of the pressing plate to the knob 68 is released. A difference between the lifting amount and lowering amount of the lifting/lowering pipe 44 at the time of ejection is detected, and whether the lead is present in the lead chuck is detected.

Title: Photodetector
Inventor: KITATANI YOSHIYUKI
IPC: H01L31/10
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a photodetector using a heterojunction of a compound semiconductor which is suppressed with distortion in a heterojunction interface caused by the difference in a coefficient of thermal expansion and has a high photo sensitivity at the short wavelength side. SOLUTION: The photodetector is formed by depositing compound semiconductors in layers. It consists of a light absorbing layer 3 which absorbs incident light and coverts it into an electric signal, a caplayer 4 grown on the light incident side of the light absorbing layer 3, and a contact layer 5 which is formed in the periphery of the incident light receiving surface of the caplayer 4 and is made of the same material as that of the light absorbing layer 3 and is thicker than the caplayer 4. By heavily doping impurities in a part of the light absorbing layer 3 which is near an interface with the caplayer 4 and in the cap layer 4 and the contact layer 5, a heavily doped impurity region 7 is formed.  As a result, distortion in the heterojunction interface between the caplayer 4 and the light absorbing layer 3 and between the caplayer 4 and the contact layer 5, which is caused by the difference in a coefficient of thermal expansion between the constituent materials, can be suppressed.

IPC: G01F23/62
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To damp reflection at the terminal end of a magnetostrictive wire to reduce error of output accuracy by providing a damper giving a mass load from the upper side of an elastic member provided on one end of a magnetostrictive sensor. SOLUTION: A plated wire 12 covered with a silicon tube 13 is tightly wound on a silicon tube 11 so as to be in the length of λ/4. Hereat, for example, by setting that one period of one wave length = 10 μsec, and sound velocity is 2.8 mm/μsec, one wave length (λ)=10×2.8, and λ/4=(10×2.8)/4=7 mm. Consequently, by winding the plated wire 12 into length of 7 mm, unnecessary reflecting wave of waveform (b) can be damped The tube 11 is inserted to the terminal end part 6 side of a magnetostrictive wire 1, and further on the tube 11, the plated wire 12 covered with the same silicon tube 13 is tightly wound by eleven times. In this way, because a grip load can be given from the upper side of the tube 11 by a more mass load and the magnetostrictive wire through an elastic material, unnecessary reflecting wave of waveform (b) can be effectively damped.

IPC: G09F9/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To make a virtual image of display exist in the farthest part and to make an area up to nearly a board surface expressed through a software technology, so that a larger feeling of stereoscopy is obtained. SOLUTION: In a housing 5, a curved-surface mirror 2 is installed opposite to a liquid crystal display unit 1. The curved-surface mirror 2 is a mirror in an aspherical toric shape and servers as a convex lens while reflecting light to generate a virtual image at a distance (farthest from the board surface). This virtual image is enlarged by the curved-surface mirror 2, so a larger field angle than the original display can be obtained. Consequently, the liquid crystal display unit 1 displays a large distance virtual image.
