Inventor: NAGANUMA MITSUAKI
IPC: H04N7/00
Filed: 1987-02-18
Abstract: PURPOSE:To attain consecutive video recording of substantial broadcast program by inserting commercial program identification information and sending the result at a sender side, identifying it at a receiver side and inhibiting its image output so as to apply on/off control of a video recording device. CONSTITUTION:A switching signal of a program broadcast is inputted respectively by means 6-8 and means 7, 9 at the sender side to decide a field period where a commercial start prediction signal and a commercial end signal are superimposed. Means 10-12 trigger the leading of a vertical synchronizing pulse extracted by means 1-5 to generate code information identifying a commercial signal. Thus, a mixer 13 superimposes a commercial start prediction signal, a commercial start identification signal and a commercial end prediction signal during the vertical blanking period and sends the result. The receiver side uses means 15-19 to detect the identification code information from the vertical synchronizing signal and uses means 20-25 to inhibit the video output during the commercial period and uses means 25, 27 to send a control signal turning on/off the video recording device.

Title: Image storage device
Inventor: FUKUI KOICHI
IPC: H04N9/804
Filed: 1986-02-20
Abstract: PURPOSE:To make a special frequency converting circuit and circuit adjustment unnecessary and to write high grade multiple picture information in a picture image memory at low cost by utilizing folding back distortion that generates in a sampling section. CONSTITUTION:A component having carrier frequency of 1/2 fsc which is side band component of chrominance signals 1100 is converted to digital signals by an A/D converter 1 and digital composite video signals 300 are obtained. Accordingly, it becomes equivalent to the case where chrominance signals having carrier frequency of 1/2 fsc are sampled at sampling frequency of 3/2 fsc and A/D converted, and therefore, digital composite video signals 300 become equivalent to conventional examples. Further, as video signals 600 of carrier frequency fsc are not converted to chrominance signals having carrier frequency of 1/2 fsc, carrier leak of 1/2 fsc generated by the conversion and tertiary higher harmonic do not occur. Thus, adjustment to make carrier leak of 1/2 fsc to low level and a special frequency converting circuit that does not generate tertiary higher harmonic are made unnecessary.

Title: Image recording apparatus
Inventor: SUZUKI NAOMICHI
IPC: B41J2/00
Filed: 1983-03-04
Abstract: PURPOSE:To make available image recording which would have been available by employment of heat-sensitive ink with a simple construction without resorting to heat-sensitive ink film and ink-recoating mechanism, by a pneumatic ink injection changing periodically in synchronization with heat generation of heating element which melts the heat-sensitive ink. CONSTITUTION:When heat generation occurs in a heater 3, bottom part of the heat-sensitive ink 8 is melted flowing to heating element 2, plugging a through- hole and solidifying to assume a solid phase after cooling by radiation of heat. When a plurality of heating elements 2 are heated through a pulse electric current selectively in response to an image signal, heat-sensitive ink found in its neighborhood is melted. As a pulse-generator 17 transmits periodically electricity to an electromagnetic solenoid 13, pressure in an air-tight chamber 1 changes in a range of higher pressure levels than the atmospheric pressure by aid of pneumatic valve 14. By this pneumatic pressure the heat-sensitive ink is injected to a recording member 9 and it is cooled and solidified to a dot to be recorded. Thus, a compact, light image recording apparatus can be formed of low maintenance costs become available without using such an expensive expendable as the heat-sensitive film.

Title: Production of high-purity metal bismuth
Inventor: ITO TOSHIAKI
IPC: C22B30/06
Filed: 1987-02-19
Abstract: PURPOSE:To produce metal Bi which has extremely high purity and is usable as a raw material for electronic materials by producing crude BiCl3 from crude metal Bi, subjecting the same to a hydrolysis treatment after rectification to form BiOCl and subjected the same to hydrogen reduction. CONSTITUTION:The crude metal Bi having about 99.99% purity is placed on a quartz boat and is put into a quartz tube. While gaseous chlorine is run in the quartz tube, the metal is heated to effect reaction in a 450-700 deg.C range to produce the crude BiCl3. After the crude BiCl3 is dropped into pure water to from the BiOCl by the hydrolysis reaction. The BiOCl is cleaned and dried and is put into a boat made of high-purity graphite. The BiOCl is heated to 700-900 deg.C in gaseous hydrogen flow and is thereby subjected to the hydrogen reduction. The Bi which has the extremely high purity and is usable as the raw material for various electronic materials is thus produced at a high yield of the raw material and at low cost.
