Abstract: PURPOSE:To make it possible to render the area of a heat meltable ink transferred to recording paper continuously adjustable, by a method wherein a heat generating temp. is made changeable according to the place of a heat generating resistor and a current flowed through the heat generating resistor is controlled. CONSTITUTION:A heat transfer type printing apparatus is constituted, for example, in such a mechanism that temp. distribution generated by the heat generation of a resistor through which a current is supplied is highest at the center part thereof and lowered toward the periphery thereof in a concentrically circular form. When a current is flowed through the heat generating resistor so as to form the temp. distribution shown by the one-dot broken line of the drawing (b), a part bringing the temp. of a heat meltable ink to the m.p. or more thereof comes to the part within a circle encircled by the one-dot broken line of the drawing (a) and, when a current is passed through said resistor so as to form the temp. distribution shown by the two-dot broken line of the drawing (b), a part bringing the temp. of the heat meltable ink to the m.p. or more comes to the part within a circule encircled by the two-dot broken line of the drawing (b). Only by controlling a currnt flowed through the heat generating resistor, the area of the heat meltable ink transferred to recording paper can be made continuously adjustable.

IPC: C21D1/00
Filed: 1978-07-25
Abstract: PURPOSE: To increase productivity and to reduce fuel consumption per unit product, by charging materials to be treated at different heat-treating temps. into a heat-treating furnace at a prescribed interval, and by heat-treating continuously the materials respectively at prescribed temp.  
     CONSTITUTION: When a steel plate 2, which is to be tempered at a°C, is charged into a continuous heat-treating furnace, all zones 1aW1g are maintained at a°C. When the plate 2 passed through the zone 1a, the temp. of the zone 1a is changed to the tempering temp. b°C for a plate 3 which is to be charged next. The plate 2 and 3 are charged at an interval of at least two buffer zones. The heat-treating furnace is divided into three sections AWC (not shown in Fugure). The plate is charged into the section A at a high speed, stayed in the section B for a prescribed time, and is charged into the section C at a high or low speed. Plates of equal treating temps. are charged continuously. Because this method mekes it possible to treat continuously materials to be treated at different temps., the productivity is increased, and the fuel consumption per unit product is reduced.

Title: Manufacture of optical fiber base material
Inventor: TAKADA HISAO
IPC: C03B37/018
Filed: 1979-07-16
Abstract: PURPOSE:To obtain an optical fiber base material with a small transmission loss by forming an OH group diffusion preventing carbide on the inside of a glass pipe and forming a deposition layer on the pipe inside. CONSTITUTION:An optical fiber base material with a very small transmission loss due to OH group is manufactured by forming a carbide layer such as a silicon carbide layer on the inside of a glass pipe.

Thus, a silicon carbide thin film is formed on the pipe inside. Deposition layer 3 based on Si and contg. P, B, Ge, etc. as a dopant is then deposited by a MCVD method, and an optical fiber base material is formed through a vitrifying process, a collapsing process, etc. and spun by drawing to obtain an optical fiber.

Title: Inverter device
Inventor: TODOROKI YUKIO
IPC: H02M5/45
Filed: 1980-06-30
Abstract: PURPOSE:To stabilize an inverter device after stopping the device by providing a comparing circuit for comparing the voltage from a smoothing circuit with a reference voltage and a logic circuit for supplying an operation signal to an inverter in response to the output signal from the comparing circuit. CONSTITUTION:An inverter device 14 is started by a start command S2, and the output voltage Vc of a capacitor 9 is larger than a reference voltage Vr. When the start command S2 is set at 0 level to stop the operation, a voltage controlling circuit 10 stops operation. However, the output voltage Vc becomes higher than the reference voltage Vr by the residual charge of the capacitor 9, and the OR gate 17 continues the operation of a frequency controlling circuit 11. Thus, the charge of the capacitor 9 is discharged through an inverter 5 or the like to a load 7. When the output voltage VC becomes lower than the reference voltage Vr, the operation of the inverter 5 is stopped. Since the inverter is operated until the residual charge is fully discharged even if the stop command is outputted in this manner, it can remove the inconvenience after the stoppage.

Title: Optical semiconductor device
IPC: H01S5/50
Filed: 1992-03-16
Abstract: PURPOSE:To realize an optical storage device wherein 'set', i.e., 'writing' and 'reset', i.e., erase is enabled by using light. CONSTITUTION:A memory cell is constituted by connecting two hetero junction phototransistors HPT1, HPT2 parallel to each other with the cathode of a laser diode LD. When the hetero junction phototransistor HPT1 is turned ON by a light input 1, the laser diode LD turns ON, and 'set', i.e., writing is performed. After the light input 1 is eliminated, the ON state of the hetero junction phototransistor HPT1 is maintained by the optical feedback from the laser diode LD. Hence the ON state of the laser diode LD is maintained, and the light output is held. When the hetero junction phototransistor 2 is turned ON by a light input 2, the laser diode LD turns OFF and 'reset' i.e., erase is performed.

Title: Amplifying circuit
Inventor: KASAGI AKIO
IPC: H03F1/26
Filed: 1982-05-27
Abstract: PURPOSE:To eliminate effectively the noise component despite the variation of the input signal level, by changing the reference voltage of a differential amplifier in response to the ratio between the signal component and the noise component. CONSTITUTION:A ratio circuit 7 delivers the voltage corresponding to the ratio between the signal component S and the noise component N. The output of an integration circuit 9 is impressed to a voltage comparator 10. When the output of the circuit 9 reaches the level set within the circuit 10, a pulse is generated from the circuit 10. This pulse is impressed to the circuit 9 to reset the circuit 9. The reset circuit 9 integrates the voltage impressed to an input terminal 8 and increases the output voltage. When the S is larger than the N with the output of an amplifier, the ratio is obtained between the N and the S. Then this ratio is weighted with a proper coefficient and subtracted from the output component of the amplifier to obtain a signal component close to the real value.

Filed: 1995-04-17
Abstract: PURPOSE: To perform the coding of data with higher compression ratio by estimating the distribution of differential data code value of the corresponding image and then adaptively switch the next set of pixels and the code set needed for coding of the data. CONSTITUTION: The coding length data are outputted as the image data output 13 through a serial/parallel converter 8 and a formatter 12. At the same time, the differential output 5 is inputted to a frequency integrator 18 for integration of the frequency in parallel to the coding operations of a code memory 6 and a coding length memory 14. The integrator 18 receives the block extraction end timing 17 and outputs the frequency count output 19 to a distribution estimator 20. The estimator 20 receives the output 19 and notifies an address pointer 22 of the number of the nearest distribution. The pointer 22 outputs the corresponding address offset value to both memories 6 and 14 as the pointer value in response to the notified estimation result 21. Then the pointer 22 generates the painter value based on the result 21 and switches the code sets.

CONSTITUTION:When a runner 1 is raced by such a way that compressed air from an air tank 11 is fed into a runner chamber 1' by fully closing a guide vane 4 and an inlet valve 7 which are upstream of the runner 1, for forcing the water level in the runner chamber 1' downward, the differential pressure between a water supply pipe 6 connected to a water supply and a casing 5 for guiding water to the runner 1 is higher than the differential pressure between the casing 5 and the runner chamber 1', and as well the cross-sectional area of a pipe 10 connecting the casing 5 to a chamber having a pressure lower than that in the casing 5, is made to be larger than a discharge pipe connecting a water supply 16 to the casing 5. With this arrangement, the pressure in the casing 5 may be higher than that in the runner chamber 1', thereby the air in the runner chamber 1' may be discharged without being sucked into the casing 5 side.
