Abstract: PURPOSE:To obtain an FRP product with a clear pattern by setting a semicured pattern sheet containing a thermocurable resin and a pattern forming material and molding material contact fiber and a thermocurable resin applied on the former, and pressing these together. CONSTITUTION:An saturated polyester resin in a resin compound 14 is semi- cured by heating a pattern sheet l at 50 deg.C.

In addition, a themocurable resin molding material 3 is set on the polyethylene film 11. Next, these materials are pressed at a pressure of about 100kg/cm<2> for about 4 minutes after lowering an upper force 22 heated at about 135 deg.C, then the pressed materials are parted from the die to peel off the polyethylene film 11, and an FRP product as desired is obtained.

Title: Logic array
Inventor: ASOU AKIRA
IPC: H03K19/177
Filed: 1979-02-07
Abstract: PURPOSE:To increase the using allowance range for the AND array by using the transistor circuit containing the constant current source to be connected to the emitter coupling for the means which transmits the output signal of the decoder circuit to the AND array. CONSTITUTION:When output level Zn and Zn' of the decoder become to the high levels along with points a-f reaching the higher potential than reference voltage VRR, corresponding transistors Q1-Qn are turned on. And furthermore corresponding bit lines of 1-n turn to the low levels respectively. The low-level potential of the bit line then is identical to potential Vn-VDn+VF which is clamped by Di, where Vn is the constant voltage due to the constant current gate of the decoder, and VF is the forward bias voltage of the diode in the array each. The clamping effect of diode Di prevents the current flowing through transistor Qn from becoming excessive and thus keeps the bit line at the normal level. In addition, the array current is increased by the clamping effect, thus increasing the speed.

Abstract: PURPOSE:To obtain a radiation resistant color television camera capable of being used in a high dosagel atmosphere by obtaining the difference between a black level when radiation is not incident and a luminance signal level after the emission of the radiation and by correcting a photographing level by the obtained quantity. CONSTITUTION:Only when a correcting action signal 505, that is, an operational signl of an operator, is ''1'', an output 508 is outputted from an AND circuit 504, which causes a relay drive circuit 503 to act, and a contact 57 is closed. At the same time, a signal holding circuit 51 is triggered. Then the circuit 51 fetches an output SBX-SBO of a subtractor 55. Here, the SBO is a black luminance signal level 54 when radiation is not incident and set by a variable resistance 55. The SBX is a luminance signal level after the emission of the radiation and set by the variable resistance 55. The circuit 51 holds the fetched output level SBX-SBO until the following correcting action is selected. Afterward, the level SBX-SBO is added to a photographing level by an adder 52, and a luminance signal after correction can be obtained.
