Title: Pulse burner with variable combustion amount
Inventor: NAKAMOTO MITSUYOSHI
IPC: F23C15/00
Filed: 1983-06-17
Abstract: PURPOSE:To enlarge the regulation range of a combustion amount and to facilitate supply of hot water and a hot air at a specified temperature, by a method wherein an exhaust gas regulator is located on an exhaust running from a combustion part, and a fuel regulator is situated on a fuel passage. CONSTITUTION:If, in a pulse combustion condition, the flow rate of fuel gas is reduced by a fuel regulator 7, an expansion force is reduced due to an increase in an air ratio during expansion, and pulse combustion is hard to maintain. If the flow rate of fuel gas is increased, an amount of the air sucked is decreased, a combustion condition worsens resulting from a decrease in an air ratio, and CO concentration in exhaust gas is increased. Meanwhile, by increasing draft resistance, produced during passage of exhaust gas, by means of an exhaust gas regulator 20, a maximum combustion amount and a minimum combustion amount can be reduced. Thus, the exhaust gas regulator 20 is operated in linkage with the fuel regulator 7 to increase a combustion amount, i.e., the flow rate of combustion gas and also increase the opening of the exhaust gas regulator, and this permits enlargement of the regulation range of a combustion amount.

Title: Gravity-compressed air driven power plant
Inventor: ISHIDA MASANOBU
IPC: F03G3/00
Filed: 1980-08-11
Abstract: PURPOSE: To secure inexpensive and unharmful energy resources by effectively  using energy (gravity) released when people moves to produce compressed air and by operating a generator with the compressed air.  
     CONSTITUTION: A compressed air compressed in a primary compression chamber 7 is transferred to a secondary compression chamber 8 through a backward flow valve 11. The secodary compression chamber 8 is smaller in size and capacity than the primary compression chamber 7. Therefore, the compressibility of air is higher. When the gravity applied to a compression plate 1 is removed and the compression plate 1 is placed under no wind condition, the compressed air accumulated in the secondary compression chamber 8 is immediately flowed into a restoration equipment 6. When the compression plate 1 is pushed up, a suction valve 10 is opened  and lets the ambient air in. The compressed air in the secondary compression chamber 8 passes through a third compression chamber 9 and is accumulated in a conventional tank through an air transmission pipe 18 and rotates an air turbine generator, thereby generating electric power.

Abstract: PURPOSE:To improve the time of access to an information storage medium by providing a magnetic flux converging member which is supported movably in the same moving direction of an optical head across a magnetic field producing source and an information storage medium arranged associatively. CONSTITUTION:When information is recorded on the recording film 3 of an optomagnetic disk 2, an irradiation position P of a desired guide groove 3a of the recording film 3 is irradiated with laser light from the objective 4a of an optical head 4 while the laser light is converged. At the same time, (y)'- directional magnetic flux phi from the magnetic field producing source 21 fitted on the optical head 4 is radiated to the irradiation point P. This magnetic flux phi passes through the irradiation point P and strikes on the projection and surface 26a of the magnetic body 26 of the magnetic flux converging member 24 supported movably in a guide groove 22c while its spread is suppressed. For the purpose, the gap between the magnetic field producing source 21 and irradiation point P and the gap between the irradiation point P and projection and surface 26a are set properly in advance to obtain nearly parallel magnetic flux at the irradiation point P.

Title: Recording of liquid jet recording device
Inventor: WATANABE KENJIRO
IPC: B41J2/21
Filed: 1988-05-09
Abstract: PURPOSE:To prevent the liquid from running at a color border while adequate image density is maintained by dividing a composition of dots to be recorded into a plurality of groups and scanning with each group. CONSTITUTION:A single pixel is composed of four microcells and a single dot is recorded in each microcell 1. In this case, dots are rerecorded in the two cells of the four by the first carriage scan and in the remainder by the second carriage scan. As printing is performed at 1/2 of the density in the first scan, the print on paper dries quickly and fixes ideally. Furthermore, no liquid runs at a different color border. As the printing of the initial scan has dried sufficiently, almost no liquid run occurs even during the second scan. In addition, a recorded image has no reverse part against the background in the second scan as shown, if the cells in which dots are printed are controlled so that the prints obtained in the first and second scans do not become overlapped. Thus adequate image density is assured.

Further, an opening and closing stopper 1 gyrating vertically and moving before and behind is provided to a front face. Since transfer of the forms 40 maximizes sliding by a dead weight of moving from upward to downward thereby, a carrying mechanism can be simplified. Further, since any driving roller for carrying the forms is not used, the forms 40 are free from generation of jamming, and an operating function can be improved.

Title: Image forming device
Inventor: MASUDA SHIYUNICHI
IPC: G03G15/00
Filed: 1984-06-01
Abstract: PURPOSE:To improve picture quality by controlling a bias voltage of the opposite polarity of the electrostatic charging polarity of a toner image which is impressed to the reverse surface of a toner surface on a recording material corresponding to the ambient humidity of the device, and preventing the sticking force of toner to recording paper from decreasing owing to high humidity. CONSTITUTION:An entrance guide plate 10 is arranged in front of the fixing roller 12 of a fixing device 11 and the guide plate 10 is impressed with the voltage of the opposite polarity of the toner polarity from a bias transformer 23. The transformer 23 inputs a bias ON/OFF signal which allows transformer output when a transistor 24 turns on and the output signal of a converting circuit 22 which converts the output signal of a humidity sensor 21 into an analog voltage. When the ambient humidity of the device rises and the output of the circuit 22 increases, the output bias voltage of the transformer 23 rises to increase the sticking force of toner to the surface of recording paper, thereby improving the picture quality.
