Title: Electric power converter
Inventor: OKUDA KIYOYASU
IPC: H02P27/06
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To minimize variation in DC output voltage from a PWM converter and accelerate response of feedback control by correcting the value of an integral term to set an electric current command value at zero when DC output voltage outputted from a PWM converter reaches an upper limit voltage value. SOLUTION: A correction circuit 23 compares DC output voltage Vdc which is detected by a current detector and is outputted by a PWM converter with a preset upper limit voltage value Vdcmax, and outputs a current command value Ip* outputted from an addition circuit 22, left as it is, in the case of Vdc<Vdcmax. In the case of Vdc⊖Vdcmax and Ip*>0, the correcting circuit 23 sets the current command value Ip* outputted from the addition circuit 22 at zero (Ip*=0) for outputting to change the value of an integral term lip* so that the current command value Ip* may be zero. That is, the value of the integral term Iip* outputted from an integral calculating circuit 21 is changed to '-Ipp*'.

Title: Copying machine
Inventor: ISOHATA ARINORI
IPC: H04N1/40
Filed: 1993-02-24
Abstract: PURPOSE:To easily race a case of illegal copying by detecting illegal copy trace information added to a recording medium to inhibit copying onto a storage medium from which no illegal copy trace information is detected. CONSTITUTION:The copying machine 1 is provided with a detection means 40 detecting illegal copy trace information added to a recording medium P, a copy inhibit means 41 inhibiting copying to a recording medium P from which no illegal copy trace information is detected, and a control means 42 controlling the copying inhibit means 41 based on a detection signal from the detection means 40. In this case, the control means 42 stores the reflecting density of the recording medium P to which the illegal copy trace information is added and outputs a detection signal when the density is other than the reflecting density. When the detection signal is inputted to the copy inhibit means 41, the copy inhibit means 41 stops turning of a 2nd feed roller 28 to inhibit the copying to the recording medium P from which no illegal copy trace information is detected. Thus, when illegal copy is made, since the illegal copy trace information is added to the recording medium P, its tracing is facilitated.

Title: Semiconductor light emitting device and manufacture of same
Inventor: ISOZUMI SHOJI
IPC: H01S5/00
Filed: 1986-03-18
Abstract: PURPOSE:To obtain a semiconductor light emitting device with a low threshold current and a high efficiency by letting the negative conductive type layer of a region wherein an active layer is formed have a higher carrier density than that of the negative conductivity type layer positioned under an embedded layer of opposite conductivity type and prohibiting the negative conductivity type layer portion under the active layer from being largely inverted. CONSTITUTION:A multilayer epitaxial film is formed on an N-type InP substrate 1, the N-type InP layer of the substrate 1 is separated to two layers with different densities wherein a layer 2 has values 5X10<17>cm<-3> and 1.5mum and a layer 2' values 1.5X10<18>cm<-3> and 0.5mum and a bottom surface formed after an etching is let reach the low density N-type layer 2. Since the density of the layer 2' has an approximate value as compared with the Zn density 2X10<18> of a P-type embedded layer 8, a P- inverted region in the layer 2' is 0.1mum thick or below, which is very small. On the other hand, since the N-type layer 2 has a sufficiently low density value as compared with the Zn density of the P-type embedded layer 8, the relatively thick P-inverted region is formed in the layer 2. Thus, characteristics that threshold current is low and efficiency is excellent can be obtained.
