Title: Manufacture of spherical shell like metal part
Inventor: KUROSAWA HIROSHI
IPC: B21D26/021
Filed: 1986-04-02
Abstract: PURPOSE:To inexpensively form the curved face of high accuracy by the curved face of the lower die only by clamping the periphery of the body to be worked between the upper side and medium base plate and pressing the body to be worked with discharging a fluid to the lower die having a projecting curved face. CONSTITUTION:The spherical shell like curved face of a parabolic antenna, etc. is formed on the lower die 2 and a fluid acting port 4 and passage are formed in the inner part. The body 1 to be worked is clamped between the projecting clamp part 11 of the upper die 10 and the recessed clamp part 8 of a medium base plate 7. In the case of pressing this body 1 to be worked to the lower die 2, it is pressed with discharging a high pressure compressed air or liquid, etc. from the liquid acting port 4. The body 1 to be worked is therefore floated by the fluid, so plastically deformed in a film shape and the curved face of high curved face precision is obtainable. The cost spent on the die can be made inexpensive because of no need for male and female dies but the lower die only for the die.

Title: Suppressing circuit of circulating zero-phase current
Inventor: TANAKA KEIICHI
IPC: H02J9/04
Filed: 1990-03-23
Abstract: PURPOSE:To prevent unnecessary operations of a ground relay by providing each phase of a bypass circuit side cableway with a current transformer and by providing a circulating zero-phase current-suppressing circuit connecting a nonlinear resistive element with the secondary side neutral residual circuit of this current transformer. CONSTITUTION:A nonlinear resistive element 2 is connected with the secondary side neutral residual circuit of a current transformer 37 provided in each of three phases of the cableway of a bypass circuit 13. The sum of respective three phases of positive- and negative-phase currents becomes zero at the time of the closed state of a switch 3 so that these currents do not flow to said neutral residual circuit of the current transformer 37 to have no relation to opening and shutting of the switch 3. On the other band, a zero-phase current flows to said neutral residual circuit when the switch 3 is shut. When the switch 3 is opened, however, a circulating zero-phase current is substantially limited by the nonlinear resistive element 2 so as to be almost negligible.

Title: Integrated circuit for television signal receiver
Inventor: FUKUDA YASUO
IPC: H04N5/57
Filed: 1984-04-12
Abstract: PURPOSE:To suppress the increase of pin number due to large scale integration by providing a switch between an output of a chroma demodulation output circuit and the 1st output terminal of the integrated circuit and connecting a luminance adjusting input and a luminance adjusting variable resistor to the 1st output terminal. CONSTITUTION:A switch 7 is turned off during the blanking period, the luminance adjusting variable resistor 4 and the luminance adjusting input 5 are connected to the 1st output terminal 11 so as to attain luminance adjustment. Then the switch 7 is turned on during the scanning period and since the impedance of the input 5 and the variable resistor 4 is sufficiently larger than the output impedance of the chroma demodulation output circuit 8, a chroma demodulation signal is outputted from the terminal 11. Thus, the increase of pin number due to large scale integration is suppressed.

Title: Image pickup signal defect detection and correction device
Inventor: SHIMURA MASAYUKI
IPC: H04N5/367
Filed: 1994-04-13
Abstract: PURPOSE:To appropriately correct a defective part with simple circuit constitution by preferentially storing a defect address for which a defect level is large when no margin is present in a storage memory and correcting a defect. CONSTITUTION:The address data of the defective part detected from image pickup signals in a defect detection part are stored in a memory 62. At the time, when no margin is present in the storage memory, a defect data storage control part 57 compares the level of the detected defective part with the defect level corresponding to the defect address data of minimum level identification data memory 58 and when it is larger, stores the corresponding defect address data in the storage memory 62. Simultaneously, new minimum identification data are formed and held. Thereafter, the defect address data are read by a control signal formation part, control signals are sent to a defect correction part for the image pickup signals and the correction is performed. Thus, defect correction for the defect address data in the successively arriving image pickup signals is appropriately performed without increasing memory capacity.
