IPC: H04N1/00
Filed: 1981-01-16
Abstract: PURPOSE:To realize the transmission of both the picture information and the voice information via a single line without using a telephone set and to increase the system efficiency, by using an interphone that performs the transmission/reception of the voice information by means of a picture information reading/recording part and a communication medium which performs the transmission/reception of the picture information. CONSTITUTION:The picture information is read at an original reading part 6 within a transmitter and with every line of an original to be transmitted. The read-out picture information is stored at a speed converting part 7 and then read by a switch circuit to be supplied to an FS modulating circuit 8. Then the picture information of each line and received the FS modulation through the circuit 8 is transmitted to an electric light line 10 having a prescribed frequency band via an interface circuit 9. On the other hand, an operator pushes a call button after operating a specific address through an operation panel. As a result, a voice is converted into an electric signal through a microphone 11 within an interphone. Then the voice is converted into an electric signal through an FF modulating circuit 12, and an FM signal of a prescribed frequency is sent to the line 10 via an interface citcuit 13 to transmit the picture information and a voice information to a single line 10.

Filed: 1978-01-18
Abstract: PURPOSE: To obtain the cathode assembly of the magnetron which features a high practical use efficiency by providing the cathode sleeve to become the end hat and the electron radioactive material which includes the mesh and is adhered to the cathode sleeve.  
     CONSTITUTION: Cylindrical mesh 6 which is cut off into the prescribed size is fitted to the circumference of cylinder 7 of a single diameter. Then core metal 8 and 9 are inserted from both ends of cylinder 7 and then extended with pressure. Thus, the area where no mesh 6 exists forms large-diameter part 5b and 5c. In this case metal 8 and 9 contain both the small-diameter and large-diameter parts, and the small- diameter part corresponds nearly to the inner diameter of cylinder 7 of a single diameter. As a result of such bulge processing, mesh 6 is pressed and held to be fixed assuredly by the pressure given from the inner side of cathode sleeve 5 and end hat 5d and 5e formed between part 5b/5c and part 5a.

IPC: G11B7/085
Filed: 1984-01-10
Abstract: PURPOSE:To obtain a stable controller with high accuracy by storing a drive current of a radial actuator in synchronizing with the rotation of an optical disc after being passed through a band pass filter taking the turning frequency of the optical disc as the center frequency and applying its signal to the actuator. CONSTITUTION:A radial error Xe of luminous flux is detected by a detector De and inputted to a servo compensating circuit P as a radial error signal Ee. A radial drive current FR of its output is fed to an adder via a changeover switch. On the other hand, the signal ER becomes an electric component ER' of the disc turning frequency via the band pass filter B taking the disc turning frequency as the center frequency and is stored in a memory M as a signal EM, which is added to the radial drive current ER in synchronizing with the disc turning at an adder via a changeover switch SM. Thus, the relative displacement between the luminous flux position and disc information track is decreased, the radial error is decreased and the accuracy and stability of the control is improved.

Title: Laminated sheet with excellent spot weldability
Inventor: TAKASE JUNICHI
IPC: B32B15/08
Filed: 1988-01-12
Abstract: PURPOSE:To obtain a laminated sheet which represents superior spot weldability, by applying a resin layer between two metal plates and dispersing specific nonmetal conductive substances in said resin layer. CONSTITUTION:A laminated sheet of this invention is so constructed that a resin layer is applied between two metal plates and conductive substance are dispersed in the resin layer. The conductive substance is nonmetal, harder than the two metal plates, having the average particle diameter of not less than the thickness of the resin layer. The conductive substances are dispersed in the resin layer by not more than 10vol.%. When the using non-metal conductive substance is harder than the two metal plates, if the particular diameter of the substance is greater than the thickness of the resin layer, the conductive substances eat deeply into the two metal plates and therefore they can be more tightly bonded with the metal plates by the friction force. Accordingly, even a small amount of the conductive substances can secure the conductive property. Since the conductive property required for the spot welding or the like can be secured by the small amount of the conductive substances, a laminated sheet having large adhering strength can be obtained.
