Title: Signal changeover circuit
Inventor: NAGAI HIROSHI
IPC: H03K17/62
Filed: 1985-06-29
Abstract: PURPOSE:To improve the crosstalk performance by providing plural switching circuits each comprising a transistor (TR) receiving bias voltage, a differential amplification TR receiving a control signal to the base and a current source. CONSTITUTION:Switching circuits 11, 12 are connected between voltage source lines L1, L2. In selecting an input signal A, control signals S1, S2 are brought respectively to a high and a low level, TRs Q12, Q16 are turned on and TRs Q13, Q15 are turned off. Thus, the TR Q11 is biased reversely and turned off and the component of the signal A produced at a point K is not attenuated but given to the base of a TR Q2 and appears at an output terminal P3. On the other hand, the TR Q14 is turned on because a voltage of a voltage source V12 is fed to the base by the turning off of the TR Q15 and the component of the input signal B is attenuated. Since the TR Q16 is also turned on, the similar effect as the TR Q14 is given and the component of the signal B does not almost appear the base of the TR Q5. Thus, even when the crosstalk exists between the base and collector of the TR Q5, the component of the signal B is nearly zero.

Abstract: PURPOSE:To prepare a frozen fish having excellent quality such as the resistance to meat cleavage, in a short freezing time with reduced energy consumption, by uniformizing the temperature of the fish from the surface to its core part prior to the cooling of the fish to the ultimate freezing temperature. CONSTITUTION:A just-caught tuna having a body temperature of 20-25 deg.C is put into a main brine tank 1 containing chilled sea-water and is precooled to a body temperature of about 5-10 deg.C.

Title: Method for transmitting power by optical fiber
Inventor: TSUJII MASAHIDE
IPC: H02J50/30
Filed: 1991-05-20
Abstract: PURPOSE:To efficiently obtain a power of large capacity by using a high energy light. CONSTITUTION:One surface 2 of a peltier element 1 is brought into contact with a constant-temperature element 4 such as a ground surface, the sea, the river, the air, etc., through an intermediate material 3 such as a heat pipe, etc., to maintain its temperature constant. Simultaneously, a metal plate 6 superposed on the other surface 5 of the element 1 is irradiated and heated with a high energy light to be transmitted by an optical fiber 7. Thus, a temperature difference occurs between both surfaces 2 and 5 of the element 1, and a current is generated in the element 1. Since a temperature of the one surface of the element 1 is held constant and the plate 6 is irradiated with the light from the fiber 7, an opto-thermal conversion efficiency is improved to obtain power of larger capacity than that of prior art.
