Title: Monolithic type beam splitter
Inventor: WATANABE KAZUAKI
IPC: G02B6/122
Filed: 1989-03-27
Abstract: PURPOSE:To integrate the above beam splitter and to reduce the size and weight thereof by successively and selectively epitaxially growing a II-VI compd. semiconductor having a smaller refractive index as a clad and the same compd. semiconductor having a larger refractive index as an optical wave guide layer on a substrate and cutting this optical wave guide diagonally with the guiding direction of light. CONSTITUTION:The lower clad layer 12, the optical wave guide layer 13 and the upper clad layer 14 are successively epitaxially grown with an SiO2 film 15 as a mask. The one end of the waveguide layer which is formed in such a manner and sufficiently confines light is cut diagonally with the guiding direction of light. The reflected light is only the (s) component when the incident light on this slope advances into the atm. of a refractive index n2 from the optical wave guide of a refractive index n1 and if the optical wave guide is cut at 66.9 deg. angle. Although the transmitted light consists of a mixture composed of the (p) component and the (s) component, only the (p) component can be taken out by forming a polarizing film on the slope. The beam splitter which can be integrated and is small in size and weight is obtd. in this way.

Title: Power device
Inventor: MISHIMA MASANORI
IPC: H05B41/24
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a power device having smaller input current distortion and high power supply efficiency from an AC power source to a load circuit, by the use of a smaller number of parts. SOLUTION: Diodes D1 -D4 are bridge-connected and constitute a full-wave rectifier. Besides the AC ends of the full-wave rectifier, the series circuit of an AC power source Vs and a load circuit 1 is connected. Between the DC output ends of the full-wave rectifier, a filter capacitor C1 is connected, and switching elements Q1 , Q2 are connected to in parallel to the diodes D1 , D2 of one arm of the full-wave rectifier respectively. The switching elements Q1 , Q2 are turned on and off alternately by a high frequency. A capacitor C3 is connected between one of the DC output ends of the full-wave rectifier and the connection point of the AC power source Vs and the load circuit 1. Consequently, input current distortion decreases, since an input current is caused to flow over approximately the whole region of the period of the power source high frequencicly.  Besides, a power supply efficiency is high, since power is directly supplied from the AC power source Vs to the load circuit 1.

Title: Controlling method for loop in loop-controlled rolling work
Inventor: ASHITA YOUICHI
IPC: B21B37/00
Filed: 1979-06-15
Abstract: PURPOSE:To widen the controllable range of the loop, and to greatly improve the rolling speed, by summing up the reference speed setting signal for the rolling roll's driving motor and the loop correction signal. CONSTITUTION:The reference speed setting signal Sn for the rolling roll's driving motor of the n-th stand and the loop correction signal (en) are inputted to the limiting amplifier 1 which then sums up these two signals. The voltage value EnT corresponding to the motor's over-speed trip set point is given as the limiting point. In case of (Sn+en)<EnT, the output signal Ex of the amplifier 1 becomes Ex= (Sn+en), and the output signal Cn of the amplifier 2 becomes Cn=en. Accordingly, the signal level of the loop correction signal en<EnT is inputted to the driving motor's speed control circuit as the control level. In case of (Sn+en)>EnT, the output signal Cn becomes EnT-Sn. As a result, the rolling roll's driving motor is operated always at a lower speed than that causing the overspeed tripping stop, even if the signal level of the loop correction signal (en) is high.

Abstract: PURPOSE:To make the increment of a fuel supply performable so properly all the time, by lowering an upper limit of a range performing air-fuel ratio feedback control when cooling water temperature becomes more than the specified value in the case where an internal-combustion engine shifts to a running state at high load or the like. CONSTITUTION:While an internal-combustion engine (a) is running, load and speed of this engine (a) are detected by a running state detecting device (b), and that whether this load and engine speed are included within the specified range or not is judged by a judging device C. And, when YES is judged, in preference to increment control over a fuel supply with high temperature of the engine (a), an air-fuel ratio is feedback-controlled so as to make it the specified air-fuel ratio on the basis of oxygen content in exhaust gas obtainable out of the said detecting device (b). And, when the cooling water temperature detected by the detecting device (b) becomes more than the specified value, each upper limit of the load and engine speed setting the specified range belonging to a judging device (c) is lowered to some extent by a lowering device (e), thereby aiming at the enlargement of a range performing the fuel increment control.

Title: Photoelectric transducer
Inventor: KURODA YASUO
IPC: H04N1/40
Filed: 1984-04-16
Abstract: PURPOSE:To extract accurately information despite of the deterioration of sensitivity of an optical sensor by comparing the output of the optical sensor which supplies a fixed light quantity with the reference level and controlling the voltage applied to the optical sensor according to the result of said comparison. CONSTITUTION:A bit terminal Q1 of a shift register SR20 outputs ''H'' and an SW1 is turned on to apply the voltage V1 to photodetecting elements b1-bn of a photosensor 7 respectively. Under such conditions, the output voltage -VSI of the element b1 receiving a fixed light quantity rises up when the sensitivity of the sensor 7 is deteriorated. Then a comparator 16 delivers ''H'' when -VSI> -VREF is satisfied, and the output pulse of an oscillator 19 is supplied to the SR20 as a shift pulse SH1. The SR20 shifts the position of ''H'' to a bit terminal Q2 from a bit terminal Q1. This SW1 and SW2 are turned off and on respectively. Therefore the voltage V2 is applied to elements b1-bn respectively to compensate or the deterioration of sensitivity of the sensor 7. The above-mentioned action is repeated to select the proper applied voltage which satisfy -VSI<= -VREF.
