Title: Photodetector array
Inventor: UDA YOSHIHIRO
IPC: H04B10/079
Filed: 1991-02-04
Abstract: PURPOSE:To detect whether an optical fiber from a transmission side is connected or not by load resistance which converts the output current of a photodiode into a voltage and FET which transmits the voltage to a next stage with a low impedance. CONSTITUTION:The input resistor 14 of the next stage is connected with external terminals 17 and 18 at every channel so as to be an input to an amplifier circuit. The output current of the photodiode 11 is converted into the voltage by integrated load resistor 12 and outputted to the terminals 17 and 18 as the low impedance signal by FET 13. That is, the anode terminal of the part 11 with the high impedance is processed inside an integrated array element and receives hardly the disturbance. Furthermore, the impedance is high in FET 13 so that the load resistance of the photodiode 11 can be made high. Thus, the output signal of the photodiode 11 is efficiently transmitted to the next stage. Then, the voltage dropping in a resistor 20 is detected and whether the optical fiber from the transmission side is connected with the photodiode 11 or not is detected, as well.

IPC: G03F7/30
Filed: 1994-01-11
Abstract: PURPOSE:To develop a resist to have a rectangular cross-section with high uniformity in the line width of resist. CONSTITUTION:Developer 14 is fed onto an exposed resist on a wafer 11 which is then rotated at 10 r.p.m.(lower than 30 r.p.m.) thus developing the resist. Temperature distribution of the developer 14 is made more uniform in the plane of the wafer 11 and the uniformity in the line width of resist is enhanced by making uniform the developing rate thereof. Furthermore, since the rotational speed is low, the developer 14 is not stirred so much and the profile of resist can be made rectangular.

Title: Remote supervisory equipment
Inventor: SUGA RYOICHI
IPC: H04M11/00
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To allow the supervisory side visually confirm a fault of each supervisory section being a supervision object and to save the communication cost. SOLUTION: When a fault is detected in any of sensors 106-1 -106-8 of a supervisory object equipment 100, a transmitter-receiver 101 of a supervisory object side equipment 100 makes a call to connect a line automatically to a transmitter-receiver 201 of a supervisory side equipment 200 and extracts a video signal from a video camera corresponding to a sensor detecting a fault and applies data compression processing to the signal and sends the resulting data to the line. The transmitter-receiver 201 of the supervisory side equipment 200 applies data expansion processing to compressed video data sent via an ISDN line network 300 and a video signal from a video camera corresponding to the sensor detecting a fault is obtained from a monitor connection terminal T13.  Thus, the image of a supervisory part corresponding to the sensor detecting the fault is displayed on a television monitor 204 of the supervisory side equipment 200 and the user confirms visually a fault of the supervised part.

Title: Pll circuit
Inventor: KATO ISAO
IPC: H03L7/087
Filed: 1992-01-29
Abstract: PURPOSE:To window the capture range of a PLL circuit. CONSTITUTION:The PLL circuit is newly provided with a frequency discrimination means 102 and a control signal generation part 103. The frequency discrimination means 102 discriminates whether or not the oscillation frequency of a voltage control oscillation circuit 106 is in a specified range by counting the inversion cycle of a data train signal 100 by means of a clock 129 which the output of the voltage control oscillation circuit 106 as a time base. When such oscillation frequency of the voltage control oscillation circuit 106 is outside the specified range, a charger pump 104 is driven with the output signal of the frequency discrimination means 102 selectively outputted by the frequency discrimination means 102. When such oscillation frequency is within the specified range, the charger pump 104 is driven by the output signal of a phase comparator 101 selectively outputted by the control signal generation part 103. Thus, since a frequency pull-in operation is made by the frequency discrimination means 102 outside the capture range (frequency take-in range) of the PLL circuit and the same operation is made by phase comparator 101 when the frequency has been pulled in, substantial capture range can be windened.

Abstract: PURPOSE:To make it possible to confirm a position with good accuracy, by moving a slider in synchronous relation to a reference signal and controlling movement on the basis of the phase difference between a signal corresponding to movement and a reference signal. CONSTITUTION:The pulse signal SD corresponding to the driving quantity of a drive means 1 driving a moving body is outputted from an encoder means 2 while the frequency of the reference pulse signal SA having constant frequency higher than the frequency of the signal SD outputted from an oscillation means 10 is divided by a frequency dividing means 11 to obtain a pulse signal C. The phases of said signal SD, SC are compared by a comparator 5 and the speed of the means 1 is controlled by control means 4-9 so that the phase difference between both signals comes to a predetermined relation.

IPC: H03F9/00
Filed: 1979-02-07
Abstract: PURPOSE:To secure the power supply isolation function or the step-up effect of the power supply voltage for the amplifier itself by using the transformer for the amplifier. CONSTITUTION:Transformer 2 is biased to the area near the saturation region of the negative direction; transformer 3 is biased near the saturation region of the positive direction; and transformer 4 is in the active region respectively. At the silence time, the square wave voltage of square wave generator 1 does not emerge at primary windings 5 and 6 of transformers 2 and 3, and accordingly no square wave voltage emerge neither at secondary windings 8 and 9 with zero of its rectification output. With supply of the positive control current from control amplifier 17, the voltage emerges at winding 5 of transformer 2; while the voltage emerges at winding 6 of transformer 3 with supply of the negative control current. Thus the square wave voltage emerged at windings 8 and 9 are rectified through rectifiers 19-22 to obtain the positive and negative output voltage.

Title: Bone cement
Inventor: SAWAMOTO JIRO
IPC: A61L33/00
Filed: 1994-02-07
Abstract: PURPOSE:To prevent necrosis of tissue and to aim at normal cure of a bone, by composing bone cement of particles consisting of biodegradable polymer and/or bioceramics and gel containing thrombin and fibrin. CONSTITUTION:Bone cement is composed of particles consisting of biodegradable polymer and/or bioceramics and gel containing thrombin and fibrin. Since this bone cement is originally in gel state, no heat is generated. The gel part containing biodegradable polymer, thrombin and fibrin is decomposed and absorbed in an organism as time passes and particles consisting of bioceramics calcareous-deposit in an organism. Tissue fixing is performed by particle-shaped matters filling and bonding to bone tissue is performed by thrombin and fibrin. Since it is important to arrest bleeding instantly, a bone fracture location or a curage part is located on a part hard to arrest bleeding, thrombin and fibrin in gel state bring effective hemostasis.
