Patent JP-S55158729-A (JP)
Title: Automatic frequency control circuit
Inventor: KITANI TERUO
IPC: H03J7/02
Filed: 1979-05-29
Abstract: PURPOSE:To omit the control for the central frequency of the discriminating output, by extracting the video carrier component each out of the turning circuit via the ceramic resonator and the capacitor and then sending the carrier component extracted to the 1st and the 2nd amplitude detecting circuits for addition of the output of these detecting circuits. CONSTITUTION:Tuning circuit 5 extracts the video carrier in the TV signal out of differential amplifier 4. Then amplitude detecting circuit 10 obtains the input from circuit 5 via ceramic resonator 9, and at the same time amplitude detecting circuit 10 obtains the input from circuit 5 via capacitor 11 each. And these outputs are added together through adder circuit 12 to obtain the local oscillation frequency control voltage for the tuner of the TV picture receiver. Furthermore, part of the video carrier component extracted out of circuit 5 is supplied to video synchronous detecting circuit 1 which gives the synchronous detection to the TV signal. Then the single-meaning decision is given to the central frequency of the automatic control voltage delivered to terminal 13 via the resonance frequency of resonator 9. Thus the control can be omitted for the central frequency of the discriminating output.

Title: Plate-like article conveying apparatus
Inventor: SHIBATA AKIO
IPC: B65G47/52
Filed: 1984-04-04
Abstract: PURPOSE:To prevent disturbance of alignment caused by a speed change by setting the trailing end of the second conveyer a little higher than the forward end of the first conveyer, and increasing the speed of the second conveyer when the center of gravity of a plate-like article is transferred in a conveying apparatus for plate-lke article such as tile or the like. CONSTITUTION:Plate-like articles (a) are aligned in a rank on the first conveyer 1, and driven at the same speed to be transferred onto the second conveyer 2 dis posed higher than the first conveyer. When the forward end of the article is detected by a detector 3, the first conveyer 1 is stopped. In such a condition, if the plate-like article (a) is small, the plate-like article is completely transferred onto the second conveyer 2, and if the plate-like article is large, the center of gravity of the article has passed the trailing end 2b' of the transport surface of the second transport conveyer 2. Accordingly, as the trailing end of the plate- like article (a) is separated from the transport surface of the first conveyer 1, even if the first conveyer 1 is stopped, braking operation will not work upon the articles, so that the alignment is not disturbed, and the articles can be transported at intervals. Thus, the articles can be transported in an orderly manner.

Title: Dry-type radio wave absorbing panel
Inventor: ISOYAMA RYOICHI
IPC: E04B1/92
Filed: 1988-03-23
Abstract: PURPOSE:To enable absorbing wide frequency band radio waves and to lighten the weight, by interposing an air layer between an outside fixture panel laminated with a secondary radio wave absorber, and an inside fixture panel of radio wave reflecting layers laminated on the rear of an inside fixture finishing material. CONSTITUTION:An outside fixture panel A and an inside fixture panel B are so joined through the medium of distance holding materials 7 that an air layer 8 may exist between both panels. Furthermore, a panel 9 is fitted to the periphery. In this way, a radio wave absorbing panel is constituted. Wide frequency band radio waves are absorbed by a primary radio wave absorber 2 mixed with minute ferrite particles and a secondary radio wave absorber 3 consisting of ferrite tiles, laminated in order to the back of a nonmetal-made outside fixture finishing material 1 of the outside fixture panel A. Besides, the air layer 8 kept between both inside and outside panels A, B shows an adiabatic effect, and the weight of the radio wave absorbing panel is reduced owing to the existence of the air layer 8.

Filed: 1989-03-22
Abstract: PURPOSE:To change the compression rate of image pickup information written once in a memory card in the presence of the compression mode by providing plural frames of buffer memory prior to signal processing so as to attain high speed consecutive shot. CONSTITUTION:A signal from an image pickup device 1 is subjected to processing such as amplification or white balance at a pre-processing circuit 2, and the information is stored to a buffer memory 5 via an A/D converter 3 and a digital switch 4. The image pickup information by plural frames stored by a digital switch 6 is selected and the information is converted into a luminance signal and two color difference signals at a low speed (the speed is limited by the signal processing speed or the write speed to a memory card) signal processing circuit 7 and recorded on a memory card 8. Since the limit of the signal processing or card write speed is not received at the consecutive shot, high speed consecutive shot is attained. Since the pickup data readout is attained for many times, the compression circuit 9 is provided to vary the compression rate of the pickup information written once and the compression rate of the information in N-preceding frame is revised in the case of the memory 5 by N-frame.

Title: Detection of slag outflow
Inventor: KOIZUMI SAKAE
IPC: B22D11/16
Filed: 1985-03-30
Abstract: PURPOSE:To eliminate the erroneous discrimination in the detection of slag outflow by determining the criterion for the slag outflow on the basis of the radiation energy level from the molten steel flow in the stage when slag does not flow out yet and the fluctuation width thereof and updating successively the criterion. CONSTITUTION:The criterion f0 (W0, sigma0) for the slag outflow is determined from the detection energy W0 in the molten steel flow in the stage when a function for discrimination starts or right after the opening or closing of a sliding nozzle and the fluctuating width sigma0 thereof. The slag outflow is discriminated from the successively updated criterion f0' (W0, sigma0) when the fluctuating factors such as the flow rate, temp. and steel kind of the flowing out molten steel are included. The erroneous discrimination of the slag outflow is thus eliminated.

Abstract: PURPOSE:To reduce the cost of the transmission line and the terminal station, by transmitting the data signal and the clock signal including the frame synchronizing signal to one transmission line and the other respectively and by separating the clock signal and the frame synchronizing signal in the receiving side. CONSTITUTION:A synchronizing signal provided with a pulse lack part or addition part correspondingly to the frame synchronizing signal is generated for the clock signal consisting of a continuous clock pulse train by synchronizing signal generating circuit 14 of transmission part 1, and the pulse lack part or addition part is detected from the synchronizing signal by synchronizing separating circuit 21 of receiving part 2 to separate and reproduce the clock signal and the frame synchronizing signal. In separation, the trigger input to a retriggerrable timer where the holding time is longer than one clock pulse period and is shorter than two clock pulse periods is used as the synchronizing signal, and the timer output is used as the frame synchronizing signal. As the result, since the frame synchronizing signal and the clock signal can be transmitted by one transmission line, constitution is simplified.

Title: Hot plate for drying veneer
Inventor: HONDA NORIYUKI
IPC: F26B15/00
Filed: 1987-03-23
Abstract: PURPOSE: To uniformize press force to a single plate, improve very much heat transfer property in a drying initial stage, and hence avoid cracking of a single plate end part owing to drying by forming a heating surface of any one side to be pressed against the single plate in a non-pressed state into a slightly recessed state in an arbitrary direction. CONSTITUTION: When a heating surface 1a of a heat board 1 is directly pressed against a veneer single sheet, a cold single plate in a water pregnated state quickly robbs heat, so that contraction stress is produced near the heating surface 1a, and in a non-pressed state the heating surface 1a presenting a convex shape in all directions is deformed to provide a substantially a flat surface whereby press force to the single plate is therefore uniformized. Thus, heat transfer property in an important drying initial stage is improved very much, and vapor is not concentrated to the center of the heat board 1 and is dissipated to the outside satisfactorily, and hence dry cracking of an edge of the single plate is avoided.
