Title: Production of ceramic porous form
Inventor: KUWABARA MITSUO
IPC: C04B38/00
Filed: 1988-02-24
Abstract: PURPOSE:To obtain the title porous form improved in mechanical strength, useful for filters and thermal insulators, by adding an alkali or acid to a ceramic powder-contg. slurry corresponding to the surface electric charge of said powder followed by forming this slurry and then calcination. CONSTITUTION:Firstly, ceramic powder is mixed with water or an organic solvent into a ceramic slurry, which is then incorporated with an alkaline solution in case the surface electric charge of the ceramic powder is negative, while in case said electric charge is positive, an acid solution. Thence, the resultant slurry is poured into a mold and solidified followed by calcination of the resulting form, thus obtaining the objective porous form. In this porous form, the ceramic powder has been granularly grown into fibrous forms 3 with a diameter of 0.1-1mu and length of 1-10mu and pores 6 with a size of <=1mu have been formed among these fibers (pores 4 are spherical ones with a size of ca. 1-50mu, being formed as a result of mutual repulsion among the respective ceramic powdery granules).

CONSTITUTION:A propeller fan of this invention comprises blades 1 obtained by stamping out a plate made of a shape memory alloy scuh as nickel and titanium into the form of an aerofoil. The blades 1 are fixed a bearing 5.

By employing such an arrangement, it is enabled to obtain a propeller fan capable of increasing its air capacity automatically along with the temperature rise while keeping the speed of rotation of the fan constant. For instance, in case that it is used as a fan for a consolidated air-conditioner, the setting angle of the blades is increased and the air capacity is increased resultantly with increasing of the atmospheric temperature even if it is operated at first at a low speed. Therefore, it is enabled to protect the motor for driving a compressor and to prevent deterioration of lubricating oil by enhancing the heat exchanging performance of a condenser and thereby lowering the condensation pressure.

Title: Waveform buffer circuit
Inventor: MORI SHIGERU
IPC: H03K5/12
Filed: 1982-03-19
Abstract: PURPOSE:To reduce the inclinations of rise and fall parts of a modulated input, by connecting a series circuit of a resistance, a constant voltage element and a capacitor to both ends of a split resistance. CONSTITUTION:A waveform like 400 emerges originally at both ends of a split resistance 4 when an input 1 increases sufficinetly. However, the changing of a capacitor 9 is started when the voltage of the resistor 4 exceeds the voltage EZ of a Zener diode 10 after connecting in series to the capacitor 9 as well as a resistor 7 and Zener diodes 10 and 11 connected with both directivities to both ends of the resistor 4. Thus a circuit functions as an LPF, and the inclination of the rise part is reduced like 700. In a fall mode, the charging of the capcitor 9 is started at a point where the input is lowered than a flat part by EZ. When the input is lowered less, the capcitor 9 is charged to the opposite polarity. Then the circuit functions as an LPF like a rise mode. In such a way, the input 400 has a rise like 700 and the inclination of the rise part is reduced.

Title: Phase modulation type carrier recovery circuit
Inventor: SETA MITSURU
IPC: H04L27/227
Filed: 1987-02-27
Abstract: PURPOSE:To contrive to decrease the synchronization establishing time by adding a carrier recovery circuit multiplying a received carrier, frequency- dividing the result and extracting a carrier signal and applying pull-in based on the extracted carrier signal at the pull-in. CONSTITUTION:Most of recovered data DATAR are in error at the initial pull-in. Thus, a phase uncertainty elimination signal Sp representing a high error frequency of occurrence is outputted from an error correction decoder 200. In receiving the phase uncertainty elimination signal, a tracking control circuit 104 stops the tracking of a Costus carrier recovery circuit 101 and uses the recovered carrier CRR from a multiplication frequency division type carrier recovery circuit 105 to apply pull-in. The multiplication frequency division type carrier recovery circuit 10 multiplies a received carrier SIN by a prescribed multiple and frequency-divides it by its reciprocal to extract the carrier CRR, then the carrier CRR is extracted quickly. Since the pull-in is applied by using the carrier CRR without sweep operation, the quick pull-in is attained.
