Title: Automatic loudness control circuit
Inventor: KATO MASAMI
IPC: H03G5/16
Filed: 1987-03-18
Abstract: PURPOSE:To control the loudness in accordance with the output signal level of a power amplifier by detecting the output signal level of a level control circuit and controlling this level control circuit. CONSTITUTION:A control circuit 12 detects the output signal level of a power amplifier 6 and controls a variable attenuation circuit 5. While a control circuit 13 detects the output signal level of a boosting amplifier 8 and controls the circuit 3. When the output signal level of the amplifier 6 is large, the attenuation value of the circuit 3 is increased together with reduction of the input signal level of the amplifier 8. As a result, a signal whose reduction is not boosted so much is applied to a load 10 from the amplifier 6. When the output signal level of the amplifier 6 is reduced, the attenation value of the circuit 5 is decreased. Thus the input signal level of the amplifier 8 is increased for production of the sounds with their boosted reduction and high ambience.

Title: Sublimation type thermal transfer recording method
Inventor: NARITA SHOJI
IPC: B41M5/382
Filed: 1990-03-14
Abstract: PURPOSE:To enable high-density image recording without causing an image to be matted by allowing plural pulses to apply a voltage to a thermal head while a recording medium is moved for one line to be recorded therein with respect to the thermal head. CONSTITUTION:While a recording medium is sent by a distance l corresponding to one line, a reference pulse 'a' is generated plural times e.g. twice at equal intervals i.e. at every period of time T and, in response to the reference pulse 'a', a voltage-applying pulse 'b' is applied to a thermal head to form recorded dots C on the recording medium. In this case, the recorded dots C are formed at the ratio of two dots to one line and are partly overlapped on one another. Two voltage-applying pulses 'b' applied in one line are equal in their width, and the widths T1, T2, T3 of the voltage-applying pulse 'b' in each line are determined in accordance with the density of an image to be recorded. In this arrangement, since the recorded dots C are partly overlapped on one another, the density at the overlapped portions becomes high and, by shifting the dots to be recorded, the area of recorded portions is increased and whitish portions are reduced. As a result, the density can be made markedly high as a whole.

Title: Production of inorganic fiber
Inventor: DOSHITA KAZUHIRO
IPC: C03B8/02
Filed: 1990-03-14
Abstract: PURPOSE:To suppress the generation of a fluctuation in the diameter of a bead or fiber at the time of sol spinning and to obtain the uniform and continuous inorg. fiber with good workability by incorporating a surfactant into the sol at the time of producing the inorg. fiber by a sol-gel method from an org. metal compd. CONSTITUTION:The org. metal compd. (e.g.; ethyl orthosilicate) is hydrolyzed in a hydrous solvent to form the transparent sol. The solvent is then gradually evaporated to increase the viscosity. The surfactant (e.g.: fluorine surfactant) is added to the sol when the viscosity attains about 50 to 3000cPs. The sol is then put into a pot and after the sol is pressurized, the sol is extruded continuously from a nozzle and is immediately dried to produce the gel fiber. This gel fiber is sintered, by which the inorg. fiber is obtd. Since the surfactant is incorporated into the sol in this way, the surface tension of the sol decreases and the sol is extruded from the nozzle under a relatively low pressure.

Title: Fused carbonate type fuel cell
Inventor: OZU HIDEYUKI
IPC: H01M8/14
Filed: 1988-03-17
Abstract: PURPOSE:To constrain the increase of the internal resistance and the occurrence of a crossover following the outflow of an electrolyte by composing an electrolyte plate with the electrolyte composed of mixed alkaline carbonate, a supporting material, and the mixture of magnesium carbonate and one selected from barium carbonate, calcium carbonate, and strontium carbonate. CONSTITUTION:An electrolyte plate is composed of the electrolyte composed of mixed alkaline carbonate, a supporting material, and the mixture of magnesium carbonate and at least one kind selected from barium carbonate, calcium carbonate, and strontium carbonate. Consequently the outflow of an electrolyte (electrolyte loss) can be reduced since the melting of the electrolyte in the electrolyte plate at the time of running and the viscosity in a liquid state can be increased without the damage of a power generation property. This enables long time running with the resistance increase of the electrolyte plate following an electrolyte loss and the occurrence of a crossover constrained.

Title: Method and apparatus for converting picture element density
Inventor: HAMASHIMA MITSUHIRO
IPC: H04N1/387
Filed: 1988-03-17
Abstract: PURPOSE:To obtain a picture element density converting picture with high picture quality in a short processing time by obtaining a data (gradation value) of a data of a picture element to be converted depending to which partial area decided in the relation with some picture elements around the said picture element the data belongs. CONSTITUTION:After an address of a picture element P(k, l) converted by a controller 24 is decided, a relative position discrimination section 16 applies area decision as to which partial area the picture element P(k, l) to be converted is included. This is implemented, for example, by forming a table corresponding the partial area and the address of the memory to each other in advance and using the table so as to decide to which partial area the picture element to be decided belongs. Then an output (product sum) assigned to each partial area is read from a product sum table 14 and the data (gradation value) of the picture element P(k, l) to be converted is calculated by using the output (product sum). Thus, the gradation obtained in such a way is stored in an output picture memory 20. Then the processing time is reduced.
