Abstract: PURPOSE:To manufacture a substrate with a homogeneous and smooth electroless Ni-P layer and a desired shape by forming the substrate on a protruded base die by electrocasting. CONSTITUTION:A peeling plated layer (strike-plated with lustrous Ni) 5 is formed on a protruded base die (with unnecessary portion for substrate formation masked 6) 4. A Ni-P-plated layer 2 is deposited on the surface of a peeling layer 5 by the electroless method. A light receiver substrate layer (made of Ag or Cu) with the necessary thickness is formed on the outer face of the layer 2 by electrocasting. A protective film (Au-plating) 7 is applied on the outer face of the substrate layer 1 for protection against blackening processing. The base die 4 is removed from the substrate 1 applied with the film 7. The removing method differs according to the type of the base die 4. The substrate 1 separated from the base die 4 is dipped in an oxidizing liquid containing nitric acid to form a black film 3 on the surface of the Ni-P film 2 on the inner face. The unnecessary film 3 is polished and removed to complete a light receiver.

Title: Magnetic recording and reproducing device
Inventor: FUNABASHI TOSHIHIRO
IPC: G11B20/02
Filed: 1985-10-09
Abstract: PURPOSE:To inexpensively reduce and eliminate quality deterioration such as cross-color interference by using a come line filter circuit constructed with a 1H delay line, which is conventionally used in a reproduction system, for removing a luminance signal component whose frequency is interleaved with a carrier chrominance component at the time of recording. CONSTITUTION:By switching changeover switches 21 and 22, the comb line filter circuit 18 is inserted into the preceding stage of a frequency converter 5 at the time of recording, and removes the luminance signal component whose frequency is interleaved with the carrier chrominance component. By switching the changeover switches 21 and 22, the comb line filter circuit 18 is inserted into the subsequent stage of a frequency converter 16 at the time of reproduction. Accordingly the quality deterioration such as the cross-color interference never occurs which is caused because a crosstalk from adjacent tracks includes a high frequency luminance signal component and which a comb line filter circuit at the time of reproduction cannot remove.

Title: Sequence controller
Inventor: KONDOU SATOSHI
IPC: G05B9/03
Filed: 1982-12-24
Abstract: PURPOSE:To put a system in optimum operation by stopping selectively the operation of only a sequence controller in trouble or all sequence controllers. CONSTITUTION:For example, a selection switch 14 is closed and some slave sequence controller gets out of order to input an error signal (ai). In this case, ''1'' is outputted by an AND gate 16 and set in an error register 17, thereby outputting a hold signal (b) and a clear signal (c) to a processor 12 and an input/output device 13. Consequently, the processor 12 enters a hold state and the device 13 stops control outputs to respective mechanism parts. Consequently, the operation of all slave sequence controllers is stopped. When the switch 14 is left open, the gate 16 generates no output even if the error signal (ai) is inputted ad neither the signal (b) nor (c) is sent from the register 17. Therefore, the operation of only the slave sequence controller in trouble is stopped.

Abstract: PURPOSE:To reduce voltage to ground for AC output, by connecting a DC circuit between a second DC/AC converter circuit and a rectifier, to the DC circuit of continuously connected ground vehicles, in parallel with each other, and by earthing the central point of the secondary winding of a transformer. CONSTITUTION:After LC power from a collector 3 is converted to AC power by a DC/AC converter circuit 10, the power is fed to a second DC/AC converter circuit 14 via an insulating transformer 20, a rectifier 12, and a smoothing circuit 13. In this case, the central point 18 of the secondary winding of the insulating transformer 20 is earthed, and so the maximum value of input voltage is (E'), but the maximum value of output voltage is E/2. As a result, without setting a transformer for neutral point earthing, voltage to ground for the AC output can be reduced, and the current of a return wire connected in parallel with an auxiliary power-supply device mounted on the other vehicle can be prevented from being turned round.
