摘要:
An interlacing television camera apparatus includes a solid-state imaging device, drive unit, delay unit, and vertical-edge correcting unit. The drive unit drives the imaging unit to simultaneously output, in a first field, a main video signal and a sub-video signal i.e., even and odd numbered lines, respectively, in a first field from the device, which represent a charge accumulated in a pixel located on a scanning line of the first field and a charge accumulated in a pixel located on a scanning line of a second field next to the first field, respectively. Next, the drive unit drives the imaging device to simultaneously output, in the second field, a main video signal and a sub-video signal in a second field from the device, which represent the charge accumulated in the pixel located on the scanning line of the second field and a charge accumulated in a pixel located on a scanning line of a first field next to the second field, respectively. The delay unit delays the first sub-video signal in the first field by one horizontal scanning period to produce a second sub-video signal, and delays the first sub-video signal in the second field by one horizontal scanning period to produce a second sub-video signal. The vertical-edge correcting unit processes the first sub-video signal and the second sub-video signal in each field and adds a result of the processing to the main video signal, to correct a vertical edge of the main video signal.
摘要:
A heat exchanger for condensing into liquid phase a vapor containing non-condensable gas components through heat exchange with a heat exchanging medium has a vessel having a vapor inlet for receiving the vapor containing the non-condensable gas components and a discharge port for the non-condensable gas components. The heat exchanger further has a tube nest disposed in the vessel and having a plurality of tubes through which the heat exchanging medium flows. The vapor containing non-condensable gas components flows towards the discharge port across the tube nest so as to be condensed into liquid phase through heat exchange with the heat exchanging medium flowing through the tubes, so that the non-condensable gas components are separated from the liquid phase and flow towards the discharge port. The tube nest is constructed to create a change in the dynamic pressure of flow of the vapor towards the discharge port to cause such a static pressure distribution in the heat exchanger that a lower static pressure is established in a region where the discharge port is provided than in a region where the vapor inlet is provided.

A resin tablet supplying apparatus comprising a plurality of tablet accommodating parts, a tablet discharge part and transporting part. The plurality of table accommodating parts are fixedly mounted at predetermined positions for accommodating a plurality of resin tablets by stacking one upon another with its central longitudinal axis being laid lateral. The tablet accommodating part is formed with a table discharge opening at its bottom end, and the resin tablet is formed generally of a pillar shape and used in encapsulating semiconductor device. The tablet discharge part discharges the tablets in each of the tablet accommodating part, by dropping down the tablets one at a time from the opening. The transporting part receives the tablet discharged one at a time by the tablet discharge part irrespective of whatever the axial length of the tablet may be, and transports the received tablet to a tablet conveying part for conveying the tablet to the next process. The tablet receiving and transportation working is sequentially repeated with respect to the tablets in the plurality of tablet stockers.

A plurality of operation units are connected to one another. The operation units include a processor, a buffer memory, and a data transfer control circuit connected between the processor and the buffer memory for controlling the data input-output with the buffer memories in the other of the operation units. The buffer memories and the data transfer control circuit are connected with one another by data buses, respectively.

Disclosed is an adjusting device for a television camera apparatus which comprises a signal processing circuit for processing a video signal, a data detecting circuit for detecting an adjusting data from the processed video signal from the signal processing circuit, and an arithmetically operating circuit for calculating a correcting data from a reference data and the adjusting data from the data detecting circuit. The correcting data is converted by a correction signal circuit into an analog correction signal. This signal is supplied to the signal processing circuit and also to a deflection circuit. The reference data and connecting data are stored in a memory section comprised of a Randum Access Memory and a non-volatile memory. Both such reference data and correcting data are stored, at the time of adjusting the camera apparatus, in the Randum Access Memory and, upon completion of such adjustment, is transferred from the Randum Access Memory to the non-volatile memory. At the time of readjusting the camera apparatus they are transferred from the non-volatile memory to the Randum Access Memory.
