Title: Image-pickup device and shading correcting method
Inventor: DEGUCHI HIROAKI
IPC: H04N5/3722
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To reduce the level of vertical direction shading by correcting the vertical direction shading based on a correction amount calculated, corresponding to the differential output of a characteristic signal level obtained from a section made as optical black at one part of a solid-state image pickup device. SOLUTION: A lens 12 applies a prescribed optical conversion on incident light from an object 11 and forms it as an optical image at the image-pickup part of a CCD 100. The level of an image-pickup signal from a DSP 16 is provided to a correction amount calculation part 3 of a shading correction part 1 and based on the difference of that level, the correction amount is calculated. In this case, the correction amount is calculated, corresponding to the differential output of a characteristic signal level obtained from a section made as optical black at one part of solid-state image pickup device. Based on the correction amount provided from the correction amount calculation part 3, a correction waveform output part 2 outputs a correction waveform and provides it to a video amplifier 14.

Title: Apparatus for detecting disconnection trouble point of electric cable
Inventor: AKIYAMA EIICHIRO
IPC: G01R31/08
Filed: 1989-06-14
Abstract: PURPOSE:To simplify measuring work by allowing a pulse time width to correspond to the distance up to a disconnection trouble point and measuring said time width. CONSTITUTION:An oscillator 11 oscillates a square wave pulse and the pulse width thereof is set so as to be sufficiently larger than the required reciprocating time of the pulse up to a disconnection trouble point. Said pulse is transmitted to the conductor P of an electric wire cable C through an amplifier 12, a damping resistor 14 and an output terminal 15a and also transmitted to a differential amplifier 16 through an amplifier 13 on the other hand. Herein, when a disconnection trouble point X is present, the pulse transmitted to the conductor P from the amplifier 12 turns back at the trouble point X to be inputted to the differential amplifier 16 which in turn compares and subtracts the input to output the pulse waveform due to propagation delay to a reflected wave measuring part 3. This output waveform corresponds to the time required in the reciprocation of the distance up to the trouble point X and the measuring part 3 shapes said waveform to modulate the same to a unit pulse train and counts the number of unit pulses to make it possible to display the distance up to the trouble point X.

Title: Division circuit
Inventor: TSUCHIYA TAKAHISA
IPC: H04N9/77
Filed: 1977-12-16
Abstract: PURPOSE:To make the division output a zero as the input signal which becomes the divisor draws near the zero, so that even when a noise enters the input, no output with an amplified noise will be produced. CONSTITUTION:Between the emitter currents of transistors Q1 and Q7, the relationship of i4/(i4+i5)=I7/(I6+I7) becomes valid. When voltage VA is applied to Q3, I6+I7=VA/R3 is obtained. Since the circuit has been formed within one and the same chip, values of VBE of Q1 to Q7 are considered all equal; and when current i0 which flows through resistance R0 is calculated if base voltages of Q6 and Q7 are denoted by VC, a relationship i0=VC/R0 is obtained, and i4 and i5 will become (VC/R+ or -R3/R1 R0XVBXVC/VA)/2. When these values are inputted to differential amplifier circuit 27, VC/R is cancelled out and output porportionate to VB/VA is obtained. When VA=0, output SD is 0, since current I6 and I7 do not flow. When VA<0, output SD becomes negative output, because current source 21B is actuated to actuate, in turn, division part 15B. In this way, even if both VA and VB change, when division output becomes 0 as the divisor draws near 0, corresponding SD can be obtained.

Title: Hot water supply and drain system
Inventor: OKADA HIDEO
IPC: F24H9/12
Filed: 1983-08-20
Abstract: PURPOSE:To enable water to be drained by a pump without providing with drain holes by attaching a hose of a length enough to reach the bottom of a tank to the pump. CONSTITUTION:Hot water heated by a solar energy collector and stored in a hot water storage tank 1 is suck from the tip of a hose 16 by a hot water supply pump 8 and then supplied from a hot water supply pipe 13. A float 17 is hung down from the tip of the hose 16, and high-temperature hot water in the upper layer is supplied. As the hot water is supplied, water is supplied from a cistern or the solar energy collector to keep the level of water in the hot water storage tank 1 nearly constant. Since the tip of the hose 16 is hung down from the float 17 to a fixed depth below water surface even the water level is varied, the supply of hot water can be smoothly made without suction of air from the hose 16 even when the water level is lowered. When too much water is drained, the suction of hot water supply pump can be continued without supplying water. The tip of the hose 16 hung down from the float 17 is lowered as the water level is lowered and reaches the bottom of the hot water storage tank 1. All water in the tank 1 can thus be discharged.

IPC: H04W36/36
Filed: 1984-07-25
Abstract: PURPOSE:To secure a communication route from a base station to a mobile station all the time by providing the mobile station with plural reception systems and using plural reception systems during channel switching. CONSTITUTION:A transmission part 10 and a reception part 11(RX1) or 12(RX2) are used during a call. This reception part varies the output frequency of a frequency syntheriser 24 under the command of a control part 26 and receives a radio wave of one optional radio frequency among radio waves sent from the base station. If the mobile station receives a speech signal of frequency fO1 during channel switching, a channel switching request and a switching destination channel number (frequency fN) are sent to the mobile station by using an out- band control signal (SVO) from the base station. Further, the base station sends a radio section continuity signal (RLP) of frequency fN1 to the mobile station so as to test the normalcy of a switching destination channel (fN). The normal station when receives the switching destination channel number (fN) with SVO of the channel of frequency fO1 places the receiver (RX2) which is not used so far in a reception state and sets it as the switching destination channel to wait for down RLP.
