Title: Method of controlling control valve for cargo-handling car
Inventor: OBA HIROYUKI
IPC: B66F9/22
Filed: 1987-07-06
Abstract: PURPOSE: To make a cargo handling work of a vehicle safe and easy by outputting a control signal which is in a low level at first to a switching valve and gradually raising the control signal to an operation process level when an operation signal of a safety switch is turned on in process of the operation of a a cargo handling operating means. CONSTITUTION: When a worker operates a cargo handling operating lever 17 before the operation of a safety switch 19 inhibiting that a lift cylinder 1 is operated by a careless operation of a cargo handling operating lever 17 and operates the safety switch 19 because he finds his mistake in the process, a control device 18 outputs a control signal which is in a low output level at first to electromagnetic switching valves 14A, 14B. Subsequently, the output level of the control signal is gradually raised up to a level corresponding to manipulated variable in process of the operation of the cargo handling operating lever 17 and the lift cylinder 1 is gradually driven up to a corresponding location via the electromagnetic switching valves 14A, 14B and a control valve 2. Thus, a cargo handling operation can be safely and easily performed without pressing the safety switch 19 again.

Title: Hydrogen combustion burner
Inventor: OGATA JUNJI
IPC: F23D14/24
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To improve heat efficiency of a plant by providing an inner cylinder forming a hydrogen gas passage, an outer cylinder forming a combustion air passage, turning blades on the hydrogen gas passage and the combustion air passage, and a NaCl nozzle for spraying an aqueous sodium chloride solution. SOLUTION: Hydrogen gas and air are introduced from a hydrogen gas supply tube 9 and a combustion air supply tube 10 into a hydrogen gas passage 3 and a combustion air passage 4. The combustion air and the hydrogen gas are mixed with the action of a spiral air stream formed by turning blades 5, 6 provided on tip end blow-off outlets of the passages 3, 4, and fired and combusted with an ignition source. A very low concentration aqueous sodium chloride solution is sprayed from a nozzle jet hole 7d to the center of a combustion flame formed in a combustion chamber as liquid droplets with a several 10μm diameter.  Hereby, mixing of the hydrogen gas and the air in the combustion chamber is promoted, and a hydrogen combustion reaction is restricted with vaporization latent heat of the liquid droplets to prevent an explosive combustion phenomenon and vibration combustion in the combustion chamber.

Title: Thin-film magnetic head
Inventor: TERADA NOBUHIRO
IPC: G11B5/31
Filed: 1991-06-13
Abstract: PURPOSE:To enable low-inductance characteristics to be secured advantageously by including a non-magnetic material layer between a slider main body consisting of ferrite and a lower magnetic pole constituting a thin-film head portion and by providing a magnetic gap with a specified spacing. CONSTITUTION:A slider main body 12 consists of ferrites such as Ni-Zn ferrite and Mn-Zn ferrite. Then, a sufficiently large recessed portion 16 is provided at an end face of a trailing side of an air bearing portion 14 at a specified depth d and a specified non-magnetic material such as glass is buried into the recessed portion 16, thus constituting a non-magnetic material layer 18 with a specified depth d. Therefore, the slider main body 12 itself does not function as a magnetic pole and low-inductance characteristics which are features of a thin-film magnetic head can be retained advantageously.

Title: Control device for engine for cogeneration
Inventor: TAKEUCHI KIYOSHI
IPC: F02D17/02
Filed: 1994-06-28
Abstract: PURPOSE:To suppress lowering of the efficiency of the whole of a system even when an engine load is fluctuated by performing operation by the number of cylinders being a value obtained by dividing a detecting load amount by an optimum output per cylinder in such a way that a present load amount is detected in case a load is varied when an engine is run at the specified number of revolutions. CONSTITUTION:When a load is generated at a generator 15, a control device 19 inputs the number of revolutions of an engine from a tachometer 12. When the number of revolutions of the engine is not the optimum number of revolutions, a given amount of fuel is fed to a cylinder under operation so that the number of revolutions attains an optimum value. When the number of revolutions of an engine is the optimum number of revolutions, a load power detected by the load detecting device 17 of the generator 15 is stored in an RAM by the control device 19 and an optimum output per cylinder stored in an ROM is read and transferred to the RAM. A computing means divides a load power, stored at the RAM, by an optimum output per cylinder stored similarly at the RAM and operation is executed at the number of cylinders based on an obtained numeral value.

Title: Developing device

IPC: G03G15/06
Filed: 1990-06-27
Abstract: PURPOSE:To prevent toner from being wastefully consumed and to obtain a stable reverse development by providing a constant-voltage element between a toner carrying member and a developing bias power source. CONSTITUTION:A Zener diode 21 is provided as the constant-voltage element 20 on the way of a lead wire 19 connecting between the developing bias power source 18 and the toner carrying member 15. When the toner electrostatically charged to be negative is supplied to a photosensitive drum from the member 15, a reverse charge which is positive is generated on the member 15 and kept on the member 15 without flowing to the power source 18 side of the member 15 by the action of the diode 21. Then, the toner electrostatically charged to be negative is attracted to the member 15 side by the positive charge and the wasteful consumption of the toner is reduced. In the case of performing the reverse development, the voltage is changed. However, when the diode 21 reaches a breakdown voltage, a conductive state is attained and the diode 21 is not at the breakdown voltage or more, then the stable development is obtained.

Filed: 1986-07-21
Abstract: PURPOSE:To prevent a fixing roller and a separating claw from being damaged due to a fact that a residual toner on the fixing roller is scraped by a copying paper separating claw in a state that it is not softened enough, by setting the pre-rotation start temperature of the fixing roller in accordance with the softening point of a toner, which is different by the kind of the toner. CONSTITUTION:The value of a pre-rotation start temperature of a fixing roller 2 corresponding to a toner to be used is set as a constant onto a control program which is processed by a microprocessor 12. A temperature signal outputted from a thermistor 5 for detecting the surface temperature of the upper fixing roller 2 is compared with the pre-rotation start temperature corresponding to the toner set in advance, and when it is decided that the surface temperature of the fixing roller 2 becomes higher, the pre-rotation of the fixing rollers 2, 4 is started by turning on the main motor of a copying machine. In such a way, the toner left on the fixing roller 2 is softened, therefore, it does not occur that the fixing roller 2 and a separating claw 11 are damaged.

Abstract: PROBLEM TO BE SOLVED: To provide a direct spread spectrum demodulator capable of being simply constituted of a digital circuit fully by demodulating information data by generating a correlative pulse, corresponding to the information data, and holding synchronism at the timing of the correlative pulse. SOLUTION: Base band signals 1a fetched into a shift register 1 are inputted as (m) pieces of signals to a ROM even 2 and a ROM odd 3, so that the correlative value of spread spectrum modulated information data '0' and '1' is provided by a PN signal for each one-chip clock. When no correlative pulse is generated in the scheduled time area, a window output 12a is synchronized with the new correlative pulse as '0' over all the time area. Further, a synchronism hold circuit operates a counter B15, gate B16 and AND gate 14 while using a synchronizing window and, even when the correlative pulse is missed, a stable information data shift clock can be provided. consequently, the synchronization of PN signal can be kept.
