IPC: H01L21/331
Filed: 1986-03-24
Abstract: PURPOSE:To obtain the hetero-junction bipolar transistor having low emitter size effect by a method wherein an external base region is formed by doping impurities in the depth reaching the second semiconductor layer but not reaching the first semiconductor layer in such a manner that an emitter region is surrounded by the external base region, and a base electrode is formed adjoining to the third semiconductor layer located in the external base region. CONSTITUTION:A wafer, on which n<+> type GaAs layer 12, an n-type GaAs layer 13, a p<+> type GaAs layer 14, an n-type AlGaAs layer 15 and an n<+> GaAs layer 16 are epitaxially grown successively, is used as a semiinsulating substrate 11. After the n<+>GaAs layer 16 located on the circumference of an emitter region has been removed, an ion-implanted external base region 17 is formed by ion-implanting impurities on the p<+> GaAs layer 14 from above the n-AlGaAs layer 15 in such a manner that the impurities exactly reach the p<+> GaAs layer 14, and a base electrode 18 is formed on the external base region consisting of n-AlGaAs. Damages are introduced in the ion implantation process, the part having a large recoupling rate per unit time is present a little in the ion-implanted external base region only. Accordingly, the emitter size effect can be reduced substantially.

Title: Optical scanning device
Inventor: KUNII YOSHIMASA
IPC: G02B26/12
Filed: 1995-03-01
Abstract: PURPOSE: To allow of knowing the revolving speed which becomes a contact state from the data by making the relation between the revolving speed and an inclined angle clear while detecting the inclined angle of a rotor with respect to a normal rotary shaft. CONSTITUTION: The angle α of a spurious light at the time of the contact starting of a rotary hollow shaft 30 when the shaft heads go from a stationary revolution to a stopping with respect to a normal rotary shaft becomes to be a plane tilt angle + the inclined angle. In this case, the shaft length of the shaft 30 is 20mm, the maximum value of the gap between a fixed shaft 25 and the shaft 30 is 0.01mm, the maximum value of the inclined angle is β=tan-1(0.01/20)=103.1sec. When the plane tilt angle is ±15sec., the gap between the shaft 25 and the shaft 30 is 0.01mm, since the distance between the surfaces of a rotary polygon mirror and the object to be scanned is 240mm, the displacement δ on an optical detector 15 becomes 0.137.  This numerical value is equivalent to a known inclined angle and a CPU recognizes it in a factory and it is stored in a RAM and it is initially set.

IPC: G06K19/077
Filed: 1988-03-18
Abstract: PURPOSE:To enhance durability by a construction wherein an IC chip is embedded in a first sheet member, the thickness of the first sheet member is reduced gradually from the area in which the IC chip is embedded toward peripheral parts of an IC card, whereas the thickness of a second sheet member is increased gradually from the area toward the peripheral parts. CONSTITUTION:A high-stiffness sheet member 6 possesses the thickest part in an embedding area 2 including the outer periphery of an IC chip 3. In this area the sheet member 6 is not laminated with a low-stiffness sheet member 5 but is present in an insular form. The thickness of the sheet member 6 is reduced gradually toward the outer periphery thereof, with a surface thereof slanted. The thinner of the member 6 is lower in stiffness and easier to bend, according to the reduction in thickness. The low-stiffness sheet member 5 is similar to the high-stiffness sheet member 6 in outer shape, but is provided with a hole in the embedding area 2 surrounding the IC chip 3, and the thickness of the member 5 is increased gradually toward the peripheral parts so as to compensate for the gradual reduction in the thickness of the member 6 form the area surrounding the IC chip 3. As a result, the peripheral parts of the IC card 1 are easier to bend than the other parts.
