Title: Burst gate pulse generation circuit
Inventor: FUJIIKE MASAAKI
IPC: H04N9/455
Filed: 1987-04-01
Abstract: PURPOSE:To always obtain a burst gate pulse having constant start position and pulse width, by constituting a PLL in which a horizontal synchronizing signal is set as a phase comparison input, and setting the start position and the pulse width of the pulse from the output of a counter in which the output of a voltage controlled oscillator with a frequency of multiplication of a horizontal synchronizing frequency is set as a clock input. CONSTITUTION:When the horizontal synchronizing frequency is decreased, the clock CK of the counter 6 is decelerated by a PLL circuit 12. When the counter 6 is 410 (=0001002), the pulse is outputted, however, since the clock is decelerated, the pulse is outputted with a large t1 compared with (t) in figure C. Also, the output of a NAND10 is outputted later since a clock frequency is decelerated, and the burst gate pulse having TL larger than the pulse with T in figure E can be obtained from an R-S flip-flop. Adversely, when the horizontal synchronizing frequency is increased, the clock is accelerated by the PLL circuit 12, and the start position of the pulse is set earlier, and the burst gate signal with short pulse width can be obtained.

Title: Mutual application system for parking lot
Inventor: ARAI MINORU
IPC: G06Q50/10
Filed: 1989-04-03
Abstract: PURPOSE:To improve the mutual availability of parking lots by securing a constitution where an idle space temporarily produced by a car in a parking lot is used temporarily by another car and the car that produced a space also uses an idle space in the parking lot of its destination. CONSTITUTION:The received information is controlled with use of a computer, a terminal equipment, a telephone circuit, etc., and the necessary information is obtained in real time. For instance, a terminal equipment is set at each parking lot and a computer is connected to the terminal equipment via a telephone circuit, etc. A member of a system offers the information on his/her own parking space via the terminal equipment, etc., when leaving the parking lot and obtains the necessary information on the parking lot at his/her destination to reserve and secure a parking space there. Thus the requirement is reduced for users to secure the parking spaces at their destinations when they move between different parking lots. As a result, the mutual availability is improved among parking lots together with increase of the economical effect.

Title: Disc-servo circuit for high quality video-disc player
Inventor: MORITA YOSHIHIKO
IPC: H04N5/781
Filed: 1985-04-17
Abstract: PURPOSE:To attain synchronized pull-in even for a large variation in revolution by changing the variable frequency division ratio when the revolution of a disc record goes out of a narrow phase control range, and by supplying a revolution control output to the disc motor based on the frequency division output. CONSTITUTION:The oscillation frequencies of the first, second, and third oscillation circuits 6-8 are fixed at one 2<1/2>-times of that of the pilot signal and at one 1/2<1/2>-times likewise. A comparator circuit 12 outputs a comparison output when the first rectification output is larger than the third one. A discriminatory circuit 13 outputs a discrimination output when the second rectification circuit level exceeds a threshold. When the rotation of the disc lowers, a control voltage is supplied to the third control terminal T3 of a variable frequency division circuit 15 in order to extend the period of the frequency division output long enough even if a PLL circuit 14 shows a wrong oscillation frequency. But when the rotation excessively rises, the control voltage is supplied to the first control terminal T1, and the period is made shorter. The output from the circuit 15 is supplied to a frequency control circuit 16 to drive the disc motor by frequency control driving at the time when the motor is being at a speed other than the normal one.

Title: Heat exchange of highly corrosion-resistant aluminum alloy
Inventor: TANIO MAKOTO
IPC: F28F21/08
Filed: 1986-04-08
Abstract: PURPOSE:To obtain a heat exchanger of long life and of highly corrosion resistant aluminum alloy which can deliver enough sacrificial anode effect of fins to a pipe material from the initial stage of use of a heat exchanger, by adding the specified rate of Zn to the alloy, and by determining the concentration of In or Sn to specified conditions in the deep part and the surface of a fin respectively. CONSTITUTION:Fins 2 are made of aluminum alloy which contains Zn: 0.1-2.0% and which also contains one or both of In and Sn in it. The Zn contained in the fins 2 makes the fins imperfect electrochemically and increases their corrosion resistance, but its effect is not enough if its concentration is less than 0.1%, while Zn will rapidly evaporate at the time of vacuum brazing if it exceeds 2.0%. In or Sn also makes the fins imperfect electrochemically. Either one or both of them can be contained in the alloy. In order to provide the constant sacrificial anode effect of the fins, the average concentration of In and/or Sn in the deep parts of fins is specified within the range of 0.005-0.1%.

IPC: G01J3/12
Filed: 1983-05-10
Abstract: PURPOSE:To vary the spectral sensitivity of a photodetector only by changing the shape of an opening of a screen by combining wedge type continuous interference filters with the screen having a proper opening to constitute the photodetector having optional spectral sensitivity. CONSTITUTION:The wedge type continuous interference filters 3, 4 are arranged with a certain distance so that all the wavelength positions of transmitted light coincide with each other or overlapped. Even if incident light (a) is not parallel light, only the optical component vertically incident to the surface of the wedge type interference filter 3 is separated from other incident light components as the projected light (b) from the wedge type interference filter 4. A douser 6 having an opening pattern 5 is arranged between the wedge type continuous interference filters 3, 4. Consequently, radiation power for each optical wavelength can be regulated and all the light projected from the interference filter 4 can be made incident to a photodetecting element 7. Thus, the photodetector of which spectral sensitivity is matched with a relative luminosity factor is obtained and the spectral sensitivity can be changed by changing the shape of the opening pattern 5.
