Abstract: PURPOSE:To prevent a cleaning rod from being struck against a part near an injection port for combustion air and from being deformed and to save energy during a cleaning maintenance work by a method wherein there are provided rails for engaging with wheels and guiding the cleaning rod to an injection port in an advancing direction of a cleaning machine. CONSTITUTION:Rails 2 are installed on a frame table 7 for each of cleaning rods 6. The rails 2 are mounted below some grooved wheels 5 of the two roll- like wheels. With such an arrangement as above, the cleaning rods 6 advance linearly under a driving of an air cylinder 9 toward an air injection port 1 so as to remove smelt, it repeats its retraction from the air injection port 1 in a linear manner so as to realize a cleaning function. Inclination or falling of the cleaning rods 6 caused by their abnormal states is prevented by the guides 8 arranged at the central portions of the wheels 4, 5. A plurality of cleaning rods 6 are vertically installed in respect to one air injection port 1., a cleaning region of the air inlet 1 is supported to cause a load of the cleaning rod 6 per one rod is reduced. With such an arrangement as above, removal of smelt or an interruption of work during a replacement of the cleaning rod under a manual operation can be eliminated.

Title: Molten metal forging method
Inventor: FUJII MITSURU
IPC: B22D18/02
Filed: 1978-09-06
Abstract: PURPOSE: To prevent segregation by quenching the molten metal to be poured and pressure processing after making a part of the molten metal solidified state and thus allowing it to solidify before the crystal structure grows coarser.  
     CONSTITUTION: After a fixed quantity of the molten metal is poured from the cooling trough 3 pressure is applied by lowering the pressure punch 2. Then, the molten metal is quenched by the cooling trough 3 and nuclei of solidification are formed in a part of the molten metal. When pressure is applied under such condition that the nuclei of solidification, after flowing into the metal mold 1, are present uniformly near the inner wall and in the central part, solidification is promoted and effected before the crystal structure grows coarse resulting in a metal structure of small crystal grains. In this way, segregation in the interior can be prevented.

Title: Sound volume controller
Inventor: SASAKI MIKIO
IPC: H03G3/02
Filed: 1987-04-30
Abstract: PURPOSE:To improve the sound volume control characteristic at a low sound volume by providing two output devices each having a smoothing circuit to the output side of a PWM converter and using an output voltage of one output device as a reference voltage for the other output device. CONSTITUTION:The output devices 2, 3 are connected to an output side of the PWM converter 1. The PWM converter 1 generates a PWM signal with a pulse width proportional to a sound volume data inputted thereto. The PWM signal is fed to the output devices 2, 3, where it is converted into a DC voltage by a smoothing circuit provided to each of them. Then the device 2 generates a DC voltage V1 proportional to the pulse width of a PWM signal while using a voltage VCC as a reference voltage. Then the device 3 converts the PWM signal into a DC voltage V2 by using the output voltage of the PWM signal as a reference voltage. In this case, in selecting a resistor R2 sufficiently larger than a resistor R3, the sound volume control voltage V2 of a sound volume control circuit 4 is proportional to the square of an input data D. The sound volume control characteristic is changed freely depending on the ratio of the resistances R2, R3. Moreover, the residual voltage by the on-resistance of transistors employed is decreased.

IPC: G06F13/12
Filed: 1988-05-06
Abstract: PURPOSE:To reduce overheads for page fixing processing by assuring a fact that each page of an input/output buffer area is stored in a main storage without fixing the pages after preparing a frame clock. CONSTITUTION:An instruction processor IP210 carries out an instruction stored in a main storage MS240 and accesses data stored in the MS240. An input/ output processor 220 is started by an input/output instruction of the IP210 and performs the transfer of data between an input/output device 250 and the MS240 based on a channel program prepared by the IP210. A memory controller 230 controls a cache memory and controls the access to the MS240. Then the frames are allocated to all pages of an input/output buffer and also input/output transfer is carried out with a frame clock acquired. Thus a fact that an input/output buffer area is included in the main storage and therefore the overheads caused by a page fixing process can be reduced.

Filed: 1980-08-09
Abstract: PURPOSE:To enable to apply a layer current as well as to obtain a small input capacity protective element, in which the large current can be applied, by a method wherein a reverse conductive region to be connected to an input gate and a high density region, which was floating formed surrounding the reverse conductive region, are provided on a low density substrate and a punch-through is given between abovementioned two regions. CONSTITUTION:For example, in the process wherein a dipole MOSFET is formed on a P<-> substrate, an annular P region 34 is formed simultaneously with channel regions 32 and 33, and an N region 38 is formed in a region 34 when source and drain regions 37, 39 and 40 are formed. The input gate electrode G1 covering the channel 32 is spread out as far as above the regions 34 and 38, and connected to N region 38 through a selective oxide layer. Through these procedures, the abnormal voltage of the G1 is punched through between the regions 34 and 38, and the breakdown of the FET can be prevented. Also, as the withstand voltage can be controlled within the range between regions 34 and 38 and a low density substrate is used, the input capacity of the protective diode can be made smaller than the ordinary junction diode.
