Abstract: PURPOSE:To eliminate the disorder of a time base such as a vertical synchronizing disorder at the time of changing-over by making a changing-over circuit which outputs a static picture signal and a usual reproducing video signal after switching these signals to an output side possible to change over only while both signals are synchronized. CONSTITUTION:From a static image signal M outputted from a D/A converting circuit 7, a vertical synchronizing signal (f) is extracted by a synchronizing separating circuit 17, phase-compared with a vertical synchronizing signal C of a reproducing video signal N by a phase comparing circuit 18, and when both phases are made coincident, a reading pulse (e) comes to an L level and the reading of a video RAM 6 is prohibited. A changing-over switch 3 is controlled by the reading pulse (e), only when the reading pulse (e) is at an H level, a changing-over armature 3c is changed over to an input terminal 3b side, and the static image signal M is derived to a monitor 4 instead of the reproducing video signal. Thus, the stable special reproduction without an image disorder can be realized.

Title: Thermal transfer recorder and facsimile device using the recorder
Inventor: ONO TAKESHI
IPC: B41J17/02
Filed: 1988-10-04
Abstract: PURPOSE:To generate securely a relative velocity between a recording medium and an ink sheet at the time of recording images by recording an image upon a lapse of time corresponding to a recording interval after a driving for feeding the ink sheet. CONSTITUTION:When a facsimile signal is received, a timer 116 is started. Feed quantities of a recording paper 11 and an ink sheet 14 can be set respectively by regulating the numbers of exciting pulses for motors 24 and 25. The timer 116 is stopped, and a time count on the timer 116 is read. A waiting time is determined based on the time count, and as the count value increases, the waiting time also increases similarly. Upon the lapse of the determined waiting time, a thermal head 13 is energized to perform transfer recording. The thermal head 13 is divided into a plurality of heat generating element groups, and when energization of all blocks is finished, the timer 116 is started counting time until the time of recording the next line. It is thereby possible to prevent the recording medium from being adhered to the ink sheet.

Title: Diversity reception system
Inventor: HIRASAWA KAZUHIRO
IPC: H04B7/08
Filed: 1988-10-04
Abstract: PURPOSE:To prevent the malfunction of a control part or a receiver due to noise before they happen by inhibiting diversity reception at the time of the occurrence of trouble in one of two reception systems. CONSTITUTION:A monitor part 15 detects the potential of a signal line 18 to detect that first and second common receivers 11 and 12 are not connected because of trouble. For example, only a first receiver 13 is always selected at the time of receiving a signal indicating that only the first common receiver 11 is connected, and diversity reception is executed at the time of receiving a signal indicating that first and second common receivers 11 and 12 are connected together. Thus, diversity reception is permitted at the time of no abnormality, and one normal common receiver 11 or 12 is selected at the time of abnormality.

Title: Production of polysaccharide from fine alga
Inventor: MATSUNAGA TADASHI
IPC: G02B6/00
Filed: 1992-09-18
Abstract: PURPOSE:To efficiently produce a polysaccharide useful as a food additive, a base material of a medicine, etc., with a high productivity while reducing the cost by fixing a fine alga secreting the polysaccharide outside the body to the surface of a luminous material, culturing it and collecting the product. CONSTITUTION:A fine alga secreting a polysaccharide outside the body, e.g. a blue- green algae Aphanocapsa halophytia is cultured till the stationary phase in a culture solution prepared by adding Na2HPO4, NaNO3, etc., as a nutritive salt to a sterilized natural sea water. After collecting the cultured algae by centrifugation, the concentrated algae are suspended in a buffer solution and 4wt.% sodium alginate solution is mixed therewith in a volume ratio of 1:1. A luminous material, e.g. an optical fiber from which the clad layer is removed is immersed in the mixture solution and taken out therefrom after about 10sec. Immediately after take-out, the luminous material is immersed in 0.5N CaCl2 solution and allowed to stand for about 1hr. Thereby, the fine algae are buried in a calcium alginate gel and fixed to the surface of the luminous material. The fixed algae are subsequently put in a culture solution and cultured for 6 day according to the aeration agitation method while supplying light to the optical fiber. The culturced solution is desalted by dialysis, thus efficiently producing the objective polysaccharide.
