Title: Heterojunction bipolar transistor
Inventor: MOMO HIDEAKI
IPC: H01L29/205
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To shorten a collector transit time of a carrier by alternately laminating first and second collector layers, in the part on the base layer side in a collector layer depleted under a bias application condition, and making the first collector layer so composition-inclined that a forbidden band width is made larger toward the semi-insulating substrate side. SOLUTION: On a GaAs semi-insulating substrate, an n<+> -GaAs collector contact layer 2 and a lower collector layer 3d of conventional structure of n-GaAs which are different from each other in impurity concentration and/or thickness, and an upper collector layer 3u of n-InXGa1- XAs are formed in this order in a crystal growth manner, with Si as dopant. The upper collector layer 3u is made a layer formed by alternately laminating a first collector layer 3a, in which composition is so inclined that a forbidden band width becomes larger toward a substrate side, and a second collector layer 3b of a uniform composition and of a thickness shorter than a moving distance of a carrier in a relaxing time of inter-valley scattering. Thereby a collector transit time is significantly shortened.

Title: Control method for surface potential of photosensitive body of image forming device
Inventor: FUKUDA HARUHIKO
IPC: G03G15/02
Filed: 1985-08-30
Abstract: PURPOSE:To correct the surface potential of a photosensitive body with high precision and to obtain stable images continuously by controlling the quantity of electrostatic charging on the basis of the quantity of variation in the surface potential of the photosensitive body calculated from the histories of the total amount of passing charges of the photosensitive body and a no-charge passing time. CONSTITUTION:When the photosensitive body 1 is not powered on, a timer counter 20 counts the charge fatigue recovery time T2 of the photosensitive body 1. Then, CS 7 turns on when electric power is supplied to load data on the time T2 and an electrostatic capacity value stored in an NRAM 19 to a CPU 16, thereby calculating the amount of passing charges of the photosensitive body 1, the electrostatic capacity of the photosensitive body 1 in copying operation, and the quantity DELTAV of variation in the surface potential of the photosensitive body 1. The quantity DELTAIc of variation by which a current Ic flowing to the photosensitive body 1 is varied is calculated by the CPU 16 so as to correct said quantity DELTAV of variation, and a signal for varying the current Ic is sent to the CS 7, which varies the output to an electrostatic charger 2 according to the sent signal. Consequently, the surface potential of the photosensitive body 1 is corrected with high precision to obtain stable images continuously.

Title: Voltage regulator
Inventor: IGUCHI YASUHIDE
IPC: H02M7/155
Filed: 1982-10-30
Abstract: PURPOSE:To stabilize the voltages supplied to a battery and a load in a simple circuit configuration by turning ON or OFF a switching element provided in a full-wave rectifying bridge corresponding to the variation in the voltage of the battery. CONSTITUTION:When a voltage between both terminals of a battery 18 is high, the collector voltage of a transistor TR22 varies in response to the difference between the battery voltage and the Zener voltage of a Zener diode 26. Accordingly, only a TR32(R) is turned ON. Accordingly, only a transistor 14(R) is fired, and only R-phase is supplied to the battery 18. When the voltage of the battery 18 decreases, the TR32 (S) is turned ON, and thyristors 14(R), 14(S) are fired. Therefore, the output of a generator 10 is supplied at the R-phase and S-phase to the battery 18. When the voltage of the battery further decreases, the TR32 (T) is turned ON, and 3-phases of R, S, T are supplied to the battery 32.

Title: Method of wire-cutting electric discharge machining
Inventor: IWAZU NAMIJI
IPC: B23H7/06
Filed: 1981-11-27
Abstract: PURPOSE:To efficiently draw wire-cutting electric discharge lines in each process for manufacturing a plurality of parts of the same form, by moving the processing locus reversely to jointly use a single processing line for adjacent parts. CONSTITUTION:A wire electrode 4 is moved in an electric discharge locus 3  from a starting hole 8 to a point (a) as shown by arrows. After the electrode 4  is moved from the point (a) to another (b), the electrode is moved back to the  point (a) and then moved to a point (d) through a point (c). The electrode 4 is  thereafter displaced back from the point (d) to the preceding one (c) and moved therefrom to a point (e). The electrode 4 is then moved from the point (e) to a  point (f) and backed to the point (e). The electrode 4 is thereafter moved from  the point (e) to a point (h) through a point (g). Backing in the electric discharge  locus is thus effected at the beginning and end of processing of parts 2. Electric discharge machining is caused to leave small uncut portions 10. The wire electrode 4 is finally returned to the starting point 8.
