Title: Cargo bed tilting device in dump truck, etc.
Inventor: SATOU YOSHIMASA
IPC: B60P1/16
Filed: 1983-12-09
Abstract: PURPOSE:To prevent unnecessary force from arising and as well to prevent a cargo bed from being deformed, by acting all forces arising from sections in a cargo bed tilting device of a link-mechanism combined-use type provided with a hoist cylinder, a lift plate, and a tension rod, upon one and the same axial line. CONSTITUTION:In a cargo bed tilting device thrust force F7 produced upon extension of a hoist cylinder 2 is transmitted to lift plates 3, 3 through a cross- head 4 to rotate upward a cargo bed 8 around a hinge 11. The lift plates 3 are pivotally attached to the free end of a tension rod 15 which is pivotally attached at its base end to a chassis frame 1. In this arrangement, the ends of the lift plates 3 are journalled by means of shafts 22 so that a force F7 transmitted through the cross-head 4 and forces F8 transmitted through the lift plates 3 act upon one and the same axial line. Further, there is so arranged that the resultant F9' of reaction forces F9, F9 arising from a bearing part 21 provided on the bottom part of the cargo bed 8 and the resultant F10' of forces F10, F10 arising from the bifurcated section 15a of the tension rod 15 act upon the same axial line with the center lines of the lift plates 3.

Title: Lifting off process by ultrasonic wave
Inventor: ICHIHARA ATSUSHI
IPC: H01L21/306
Filed: 1983-12-08
Abstract: PURPOSE:To save processing time and simplify the processes by a method wherein a substrate is placed on a part of vessel filled with solvent with its diameter larger than that of substrate to provide the part under the vessel placing the substrate with ultrasonic vibration. CONSTITUTION:When an ultrasonic vibrator 40 is vibrated for example in the direction of arrow A, this ultrasonic vibration is transmitted to a substrate 10 through the intermediary of a bottom plate of a vessel 20 to make the substrate 10 start the ultrasonic vibration. Resultantly the part of the substrate 10 coming into contact with aceton 30 is subject to cavitation to make the unnecessary metal such as aluminium etc. peel off easily floating in the solvent as small pieces. The solvent aceton 30 starts convection rising up from the vibrator 40 and falling down toward the part not being vibrated. Consequently in case the substrate 10 is picked up after processing is finished, the small pieces of metallic foil such as aluminium etc. may not stick on the substrate 10 since said small pieces of metallic foil peeled off from the substrate 10 floating in the aceton 30 are sedimented and deposited on the parts whereon the substrate 10 is not placed floating along said convection as shown by arrow B.

Title: Time division multiplex separation circuit
Inventor: YAMATO SEIICHI
IPC: H03M9/00
Filed: 1990-09-05
Abstract: PURPOSE:To miniaturize a circuit scale and to reduce power consumption by permitting a rearrangement means to take in the output of a serial-parallel conversion means and to rearrange a parallel output based on the detection result of a frame synchronism detection means. CONSTITUTION:The serial-parallel conversion means on a reception side serial/ parallel-converts a reception signal in the same parallel degree as a period when a frame bit appears in the reception signal. Thus, the frame bit appears in orbit in the output of the serial-parallel conversion means 1. The frame synchronism detection means 3 searches respective bits of the output of the serial/parallel conversion means 1, detects the bit where the frame bit appears, controls the rearrangement means 2 and rearranges the output of the serial- parallel conversion means 1 so that the bit is positioned in a prescribed bit phase. Thus, whole constitution is miniaturized and power consumption is saved.

Abstract: PROBLEM TO BE SOLVED: To obtain high electromagnetic conversion characteristics and CSS durability by controlling the surface roughness of the principal plane by bringing the max. height, center line roughness and the ratio of these values measured by an atomic force microscope(AFM) into specified ranges. SOLUTION: When the surface roughness on at least the principal plane of a glass substrate is measured by an AFM, the surface has 0.2 to 2.5 nm Ra, 3 to 25 nm Rmax and 3 to 35 Rmax/Ra so that the obtd. glass substrate for a magnetic recording medium such as a magnetic disk has <=1.2 μ inch glide height, thereby preventing a magnetic head to cling to the glass substrate. Here, Ra and Rmax stand for line roughness and the max. height, respectively, each specified by JIS B0601. The ratio Rmax/Ra measured by an AFM indicates the distribution (uniformity or scatter) of the height of projections on the rugged substrate surface. The glass substrate contains at least alkali metal oxides and <3 mol% alkaline earth oxides.

Title: Automatic gain control circuit
Inventor: MINAMOTO TSUNESUKE
IPC: H03G3/30
Filed: 1984-11-06
Abstract: PURPOSE:To keep the gain of an amplifier circuit constant by using a voltage proportional to an input signal of the amplifier circuit for the control of a variable resistive element. CONSTITUTION:A level detector 11 is a full wave rectifier circuit, its output current (i) is proportional to the absolute value of an input signal voltage V1 and a resistance R2 of the variable resistive element 12 consisting of, e.g., an LED and a photoconductor is changed inversely proportional to the control current (i). Thus, an output V2 of an amplifier 13 is expressed in equation (where; R1 is a resistance of a resistor K is a proportional constant) and the output signal voltage V2 is constant independently of the input signal V1. A constant output is obtained at a level over the input signal level V10 and the amplifier acts like an amplifier with a limiter having a constant gain decided by a bias current at the input signal level below the V10.

Title: Method and device for preventing adhesion of slag in melting furnace having secondary combustion chamber
Inventor: HOSHINO YASUSHI
IPC: F23G5/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent molten slag from being solidified and sticking to the inner wall of a furnace, by mixing the air which is alternately heated by heat storage burners with fuel to blow it into the secondary combustion chamber. SOLUTION: Piping 13 from a heat storage burner mechanism 12 and a fuel pipe 14 are connected to the secondary air outlet 7 from which the secondary air is blown into the secondary combustion chamber 6. Burners 16 and 17 of the heat storage burner mechanism 12 are alternately ignited and burned. The inside of the combustion chamber 15 is gradually warmed up, and it is brought to high temperatures in the range of about 800 deg.C to 1,000 deg.C. The air which became a high temperature is mixed with the fuel from the fuel pipe 14 at the secondary air outlet 7 through the piping 13, and then the combustion gas, which has a sufficiently high remaining oxygen concentration at a slag melting point or higher, is blown into the secondary combustion chamber 6.  Thereby, cooling of slag does not occur at the secondary air outlet 7, and the molten slag does not stick to the inner wall surface 1b of the furnace.

Title: Low pollusion combustion for sludge generated in reproducing used paper
Inventor: NAKAMURA MITSUO
IPC: F23G5/02
Filed: 1986-10-01
Abstract: PURPOSE:To enable an almost complete secondary oxidation combustion to be performed without requiring a supply of energy of auxiliary fuel from outside except an initial firing or ignition by a method wherein sludges are granulated in advance and dried, partial carbonization, generation of combustible gas and gasification of tar substance and the like are performed rationally during primary combustion and then the final state of sludge is brought into contact with sufficiently heated secondary air. CONSTITUTION:Sludge are granulated or dried in blocks, the particles are fed through a hopper 1 to make a complete filled condition and ignited through a secondary air flowing port 9. As the fire approaches a primary combustion zone 5, a closed state of an ignition heater 7 is released to feed primary air. At this time, the primary combustion and secondary combustion are regularly started. The primary combustion air causes each of gases to be flowed in such a direction as opposite to that of the movement of the ignited object and the secondary combustion air causes it to be flowed in an opposite direction, both discharged portions are placed at an intermediate part to cause combustible gas generated under a primary combustion to be ignited under a contact oxidation process at the surfaces of block- like or particulate ashes containing hot carbonate, and then carbon contained in the ashes is oxidized to make a more complete secondary combustion.
