IPC: G11B5/31
Filed: 1987-06-23
Abstract: PURPOSE: To uniformly form the thickness of a masking material at positions and to manufacture a magnetic thin film having high dimensional accuracy by employing a plating film by a plating method as the masking material for etching the film.  
     CONSTITUTION: A pattern of an organic resin film 7 is formed on a substrate 1, an upper magnetic thin film 3 is deposited by a sputtering method thereon, and a copper plating film 11 is deposited in thickness of 1.5W2 times as large as the thickness of the thin film 3 by a plating method. The film 11 is coated with a photoresist 12, and etched by an ion milling method to be patterned. When the photoresist is removed and with the film 11 as a masking material the thin film 3 is etched by an ion milling method, the patterning of the thin film 3 is completed. The film 11 used for the masking material is removed by dissolving it by wet etching with aqueous ammonium persulfate solution.

Filed: 1980-11-06
Abstract: PURPOSE:To prevent the abrasion of apparatus parts such as upper bells in accordance with the discharging of raw materials by adding tertiary equalizing pressure in the pressure equalizing in the top part of a two bell type furnace. CONSTITUTION:Part of the gas half cleaned from the gas in a furnace 7 is conducted through a pressure equalizing pipe 11 into an upper bell hopper (pressure equalizing chamber) 3, whereby a primary pressure equalizing is accomplished. The gas in the furnace 7 then is conducted through a pressure equalizing pipe 12 into the chamber 3, whereby a secondary pressure equalizing is accomplished. A lower bell hopper 5 and the inside of the furnace 7 are communicated with a pressure equalizing pipe. A secondary pressure equalizing valve 17 is then closed, and a tertiary pressure equalizing valve 21 and a pressure regulating valve 22 are opened to be ready for introduction of gaseous nitrogen or the like through a tertiary pressure equalizing pipe 20 into the chamber 3. Thereafter, an upper bell 4 is opened to  charge raw materials A immediately or after a constant time, and gaseous nitrogen  or the like is introduced so as to maintain the presure in the chamber 3 (equal to  the furnace top pressure) in accordance with the discharging from the chamber 3 in the raw materials A. Then, the abrupt ascending of the rough gas along the slope 4'  of the upper bell 4 is obviated and the abrasion of apparatus, devices, etc. is  prevented.

Title: Operation confirmation system for master remote controller of radio equipment control system
Inventor: HOSOYAMADA SUMIYUKI
IPC: H04Q9/00
Filed: 1987-06-25
Abstract: PURPOSE: To securely confirm the operation of a master remote controller from a slave remote controller side by providing the slave remote controller with a means which detects a detection current which flows between the master and slave remote controllers and indicates that a detected control current is smaller than a prescribed value in such a case.  
     CONSTITUTION: When the press-to-talk switch 41 of a transmitter 4 is pressed, the control current flows between the slave remote controller 2 and master remote controller 1 through a signal line 3 and when this control current is detected by a current detecting circuit 5, the master remote controller 1 transmits a voice from the transmitter 4 by radio with a carrier. At this time, the control current is detected by the current detecting circuit 5 of the slave remote controller 1 and the detection current is outputted to a display part 7. If the prescribed current does not flow between the master remote controller 1 and slave remote controller 2 because of the bad state of the signal line 3 and the master remote controller 1 does not operate, the control current detected by the current detecting circuit 6 of the slave remote controller 1 decreases below the prescribed value and the LED of the display part 7 lights to inform a sender that the master remote controller 1 does not operate.

Title: Power amplifier
Inventor: SATOU TAKESHI
IPC: H03F3/20
Filed: 1978-12-18
Abstract: PURPOSE:To reject the switching distortion, by providing the clamp voltage circuit in which the bias voltage is fluctuated with the voltage at the middle point of output at all times and turning on and off the switching element with the bias voltage. CONSTITUTION:When the input signal is positive half cycle, the diode 15 and transistors Tr3, 5 are conducted and the voltage is produced across the emitter resistor 9 to supply the current to the load 11. Further, the bias circuit 2 is operated to cut off Tr4, 6. But, since the voltage of the outputs a, b of the clamp circuit 14 is always following to the voltage at the middle point o, the bias voltage is not  changed with Tr4, 6 to block to cut off Tr4, 6. At the negative half cycle of input signal, entirely converse operation is made. As a result, the waveform of current flowing to Tr5, 6 is shifted from the zero point by the bias current with the circuit 14 to prevent the production of switching distortion.

Abstract: PURPOSE:To prevent filming occurring and to stably secure the attached quantity of toner and the electrostatic charged quantity of the toner for a long time by constituting a part having the holding function of electric charge of a material having more elasticity than a material constituting the other part on the surface of a developer carrier. CONSTITUTION:The part which has the holding function of the electric charge and a part which does not have the function coexist on the surface of the developer carrier 20 with a fine area. Besides, the part which has the function is constituted of the material having more elasticity than the material constituting the part which does not have the function. That means, many fine closed electric fields are formed near the surface of the carrier 20 by selectively holding the electric charge on the surface of the carrier 20. Then, developer 60 is carried on the surface of the carrier 20 by the fine closed electric fields and an electrostatic latent image is made a visible image by the carried developer. Thus, the filming of the toner is prevented from occurring and the attached quantity and the electrostatic charged quantity of the toner are stably obtained for a long time.

Title: Idle-binding prevention method in stronglytightening/ packing machine
Inventor: INOUE YUKIO
IPC: B65B13/22
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent band from coming off a packed item, binding a slide table, and ending up being cut or splitting, in an automatic packing machine equipped with a band sealer unit, a normally/reversely rotating feed roller, a band-tightening device which moves in conjunction with the sealer unit, a slide table, and a separator. SOLUTION: By providing the feed roller of a packing machine with a rotation detector which measures an amount of the pullback of band, an amount Rx of pullback in each packing is measured. Also, the measured value is compared with an amount R5 of the pullback of a dummy packed-item whose peripheral length is shorter than that of an aimed packed-item P. In the case of RX>=RS, the band is supplied only a specific length by normally rotating the feed roller, thereafter an idle loop is formed by performing a normal operation such as tightening the band, and the machine is stopped.

Title: Method for preventing decarburization and oxidation of inner surface of pipe in direct-fired furnace
Inventor: ICHIKAWA MITSUAKI
IPC: C21D9/08
Filed: 1988-06-24
Abstract: PURPOSE:To control the decarburization and oxidation of the inner surface of a pipe without using an inert gas by fixing a plug to at least one end of the pipe at the time of heat treating the pipe in a direct-fired furnace. CONSTITUTION:When a steel pipe, etc., are heat-treated with a direct-fired furnace, a plug is fixed to at least one end of the pipe. The plug is made of a material capable of withstanding the heat-treating temp., and asbestos can be stuffed into the end, for example. When both ends are plugged, one end must be permeable to air. By this method, the infiltration of an in-furnace combustion gas into the pipe is prevented, the oxygen in the air staying in the pipe from the outset is consumed in oxidation, and hence subsequent oxidation is prevented. As a result, the decarburization and oxidation of the inner surface of the pipe can be controlled even if the air in the pipe is not replaced by an inert gas.
