Title: Image pickup device and method for generating automatic exposure control signal
Inventor: NUMATA SHINICHI
IPC: H04N5/232
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent automatic exposure control signal corresponding to a size of an object. SOLUTION: The user operates a key operation section 15 to set a valid photometric frame corresponding to a position and a size of an object. For example, the user selects the valid photometric frame by selecting one or pluralities of photometric frames from a photometric frame pattern consisting of pluralities of photometric frames set to a screen image. A detection circuit 18 being a component of an automatic aperture control system and a detection circuit 20 being a component of an AGC circuit detect an image pickup signal corresponding to the valid photometric frame to obtain a 1st detection signal and applies weight detection to the image pickup signals not corresponding to the valid photometric frame to obtain a 2nd detection signal and add the 1st and 2nd detection signals to obtain a detection output signal.  A weighting coefficient to obtain the 2nd detection signal is calculated by multiplying a ratio of an area of the valid photometric frame to a total area of the screen image with a mean photometric weighting coefficient whose value is the unity or below.

IPC: H02M7/48
Filed: 1978-06-30
Abstract: PURPOSE: To retain equal radio waveforms of respective phases and readily switch the waveform shape of an inverter by synthesizing symmetrical triangular wave repeated in front and rear half periods and a standard value with a gate signal and controlling the number of pulses to the number of standard value.  
     CONSTITUTION: A signal 3072f obtained by the 3072 times of the inverter fundamental frequency f if applied to a 1/512 frequency divider 1 and an up and down counter 2. The frequency divider 1 thus produces its output signal of six times of the inverter fundamental frequency f, which is applied to a sexenary ring counter 3 and to the up and down counter 2 as an up and down instruction. The counter 2 produces upon reception of the input a triangular wave TRI. This wave TRI is applied to one input of a digital comparator 4. The comparator 4 receives at its other input information from a memory 5 to comapare the wave TRI with the information. The address of the memory 5 is determined by the output F of a frequency detecting circuit 6. The output of the comparator 4 is processed in a logic processor 7, which thereupon produces a modulation control signal L, which is then applied to a waveform synthesizer 8, which synthesizes the signal L with the input to the counter 3 to thereby produce a gate signal.

Title: Improved gas diffusion electrode
Inventor: MORIMOTO TAKESHI
IPC: H01M4/86
Filed: 1985-04-16
Abstract: PURPOSE:To improve endurance of an electrode together with preventing an electrode performance from falling, by applying water-repellent coating on the exposed surface of a metallic porous material which forms a collector. CONSTITUTION:A collector is formed of a metallic porous material, having a metallic water-repellent coating on its exposed surface. An electrode layer, which is permeable to gases, is needed to preferably be 0.1-3mum in maximum porous diameter, 40-95% in porous factor, and 20-500mum in thickness so as to become impermeable to liquid. As fluorine-filled polymer forming a water- repellent layer, it finds it desirable to user two kinds of fluorine-filled polymers, that is, PTFE and fluorine-filled polymers having a lower melting point than PTFE. Hence, because the fluorine-filled polymer, with a low melting point, functions as adhesive, superior adhesion of both can be performed without making electrode performance to fall. As the low melting point fluorine-filled polymer, its melting point is required to be smaller than the of PTFE, by 40-170 deg.C.

Title: Radio selective call receiver
Inventor: TSUKUDA NAOKI
IPC: H04B1/16
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the increase in the device cost and making the device larger while evading the influence of noises and the characteristic deterioration of a radio part by cutting the power that is supplied to a notification means from a power supply while a receiving means is operating. SOLUTION: A control part 102 outputs a control signal for intermittently operating a radio part 101 and also to turn on a switch 104 to operate a vibrator 103, when a call addressed to the part 102 itself is received. A power supply 105 supplies the power to both parts 101 and 102 and the vibrator 103. In this case, the operating of the vibrator 103 is inhibited in timing, when the part 101 operates. In other words, the vibrator 103 is separated from the supply 105 via the switch 104, when the part 101 is turned on. Thus, the part 101 being affected adversely by the drive noises of the vibrator 103 can be avoided. Furthermore, the current consumption is reduced since no voltage drop exist in the supply 105 and no current flows to the vibrator 103.
