Title: Logical circuit
Inventor: TAKAHASHI AKINORI
IPC: H03K19/00
Filed: 1981-06-04
Abstract: PURPOSE:To obtain an injector current supply circuit which can supply current exerting no influence on the characteristics of I<2>L elements even if temperature is changed by earthing the output current of a constant current source through resistnaces and 1 p-n junction element. CONSTITUTION:Injector current I'SUM to be supplied to n I<2>L elements is shwon by an formula. In the 2nd term of the formula, the temperature coefficience VBE of a collector-base connecting transistor QO and the temperature coefficience VBE of a injector current supplying pnp transistor Q'2i (i=1, 2,...n) are offset each other, so that an injector current supplying circuit which scarecely shows temperature coefficience upon the electric characteristics of the I<2>L element. If a constant current source IS coincides with the injector current I of each I<2>L element, the 2nd item is erased. Consequently, if there are (n) injector stages, resistance RS is made equivalent to (n) resistances R arrayed in parallel, extremely simplifying its design.

Title: Smoke sensing element
Inventor: TSURUMI SHIGEYUKI
IPC: G01N21/59
Filed: 1985-04-24
Abstract: PURPOSE:To obtain a smoke sensing element by which plural pieces of elements can be increased and installed in the place of a wide range and the wiring is not increased, by sensing the attenuation of a transmitting light or the reflected light of the rays of light which are led into an optical fiber, caused by a fact that smoke intrudes into a space part. CONSTITUTION:When a laser beam is made to pass through an optical fiber 1a, the laser beam is emitted from the optical fiber 1a in a smoke sensing element and converged by a spherical lens 3a, propagated through an air tank 4, passes through a spherical lens 3b and enters into an optical fiber 1b. The air tank 4 has an air-gap 5 through which the inflow and the outflow of the open air can be executed, therefore, in case when smoke exists in the open air when a fire is generated, the smoke enters into the air tank 4. Also, when the laser beam is propagated through the air tank 4, the laser beam is attenuated by the smoke. By sensing this attenuation as a transmitting light, or a reflected light from the smoke sensing element, by a photodetector which is provided on the outside, the existence of a fire can be informed.

Inventor: WATANABE SHUZO
IPC: F23C10/16
Filed: 1990-03-30
Abstract: PURPOSE:To obtain the bed-material circulator of a pressurized fluidized-bed boiler capable of preventing variations in temperature of a fluidized bed in casting the bed material and of avoiding troubles due to air that is the transfer gas by providing a bed-material circulation means which couples a bed-material preserver with a boiler body and circulates the bed material with steam as the transfer gas. CONSTITUTION:A part of combustion gas in the fluidized bed in a boiler body 1 is absorbed by a heat exchanger tube 6, and steam is evolved by its absorption heat. This high-temperature steam flows into a steam line 7 and is partly fed into a stem turbine and the like: in the case of steam turbine, the turbine is rotated to generate power. The residual steam enters an L valve 12 through a transfer gas line 13. This enables a small amount of bed material in the bed material preserver 9 to be cast satisfactorily into the fluidized bed as by extrusion by steam through the L valve 12. Casting the bed material satisfactorily by steam from the bed preserver 9 through the L valve 12 prevents steam from affecting the fluidized bed in spite of entrance with the bed-material.

Abstract: PURPOSE:To improve operability and to prevent the impossibility of deciphering when receiving an FSK by switching the oscillation frequency of a beat oscillator between prescribed frequencies for upside and downside hetelodyne corresponding to the operation of a spectrum inversion operating means when receiving a CW and the FSK. CONSTITUTION:On a control panel, a reverse switch 80 is provided to execute the inversion operation of a frequency spectrum.

Therefore, there is no disagreeable feeling for the operation and the operability is improved.
