Title: Sampling frequency conversion system for multiplex signal
Inventor: ONISHI MAKOTO
IPC: H04J1/00
Filed: 1992-10-16
Abstract: PURPOSE:To process a multiplex signal as it is and also to omit a high speed operating element by applying a device which can convert the sampling frequency of a TDM(time division multiplex) signal in an optional conversion ratio. CONSTITUTION:A digital interpolator also serves as a filter which deforms a time conversion coefficient. Then the input TDM signal is divided into each individual channel signal by a time division separator switch 50 and stored in the delay element groups 511-514N. The signal of frequency fS1 synchronized with the input TDM signal is added to the reset signal of a clock device 55. The signals are read out by the multiplexers 580-58N every output sampling frequency 4fS2 and supplied to the coefficient multipliers 520-52N. Then a latch 57 hold the interpolation time tau by the output sampling frequency fS2 and reads out the time coefficients a0-an written in a coefficient ROM 54. These time coefficients undergo the multiplication processing through the coefficient multipliers 520-52N, are integrated by the address/subtractors 531-53N, and are transmitted as the TDM signals converted into the frequency 4fS2.

Title: Overcurrent detector for electric rolling stock
Inventor: MIYAZAKI REI
IPC: B60L3/00
Filed: 1986-11-25
Abstract: PURPOSE:To detect the overcurrent of a main circuit surely and correctly in any vehicular speed and any notch condition, by adding a control current pattern to a bias signal to obtain a protective pattern signal. CONSTITUTION:A control current pattern generating circuit 10 outputs a control current pattern signal Ip to an adder 12 and an electric power converter control circuit 11 based on a notch signal N and a speed signal V. The power converter control circuit 11 inputs the control current pattern signal Ip and an actual current signal IA and outputs a control signal G to a power converter 2. On the other hand, the adder 12 adds the control current pattern signal Ip to a bias signal IB and outputs a protective pattern signal IPB. A comparator 14 outputs a trouble signal F to the protective relay coil 15C of a protective relay 15 when the actual current signal IA has become larger than the protective pattern signal IPB.

Title: Semiconductor laser device
Inventor: YAGI TETSUYA
IPC: H01S5/223
Filed: 1986-11-24
Abstract: PURPOSE:To allow the effect of the current inhibiting layer to be held even if the optical output is increased by forming in the current inhibiting layer a current inhibiting region which is of the same conductivity type and has a forbidden band width broader than the surrounding region. CONSTITUTION:When a semiconductor laser reaches the oscillation state, part of the light is absorbed by a first current inhibiting region 5 made of n-GaAs and is converted to an electron-positive hole pair. Electrons do not flow out into a second clad layer 4 or a third clad layer 8, but they are stored in a current inhibiting layer comprised of the first current inhibiting region 5, a second current inhibiting region 6 and a third current inhibiting region 7. If electrons are stored in the current inhibiting layer, the band in the current inhibiting layer will lift. However, even in the maximum lift state, the barrier effect of the valence band of the second current inhibiting region 6 on the minority carrier is not lost, whereby the current inhibiting effect is maintained.

Title: Production of resin powder with low content of residual vinyl monomer by steam treatment of vinyl chloride resin slurry and its apparatus
Inventor: MATSUDA ETSURO
IPC: C08F6/24
Filed: 1992-09-25
Abstract: PURPOSE:To obtain a method for producing resin powder in which the residual vinyl chloride(VC) is removed from an aqueous slurry of vinyl chloride resin (PVC) containing the residual VC as much as possible and the foaming in the aqueous phase can simultaneously be suppressed to eliminate bubbles and an apparatus for producing the resin powder. CONSTITUTION:A slurry to be treated is charged onto the topmost plate 1 of a column type treating apparatus 13 having the perforated type plates 1 assembled therein and steam is blown from the lower part of each plate 1 into the slurry. Steam is simultaneously jetted from a jetting nozzle 5 installed above the slurry liquid surface thereon. Furthermore, hot water is jetted from a hot water jetting ring onto the undersurface of the plate just above jetting nozzle and the inner wall surface of the apparatus for washing. Thereby, the sticking of PVC particles in the slurry to the apparatus wall, clogging of a condenser, etc., are eliminated without mixing foreign materials. The VC is nearly completely removed from the discharged PVC without producing a situation in which the VC, etc., penetrate from the column top into the condenser.
