Title: Device for catalytic combustion
Inventor: KAWASAKI YOSHITAKA
IPC: F23D11/40
Filed: 1988-06-06
Abstract: PURPOSE:To maintain complete combustion in a large area in the amount of combustion not by the control of the amount of air supply in proportion to the decrease in the amount of fuel supply but by the increase in the ratio of air in the area in which the amount of fuel supply is small. CONSTITUTION:The fuel is heated by a heater 5 and vaporized in a vaporization chamber 4 and the vapor is mixed with air. Then the mixture is led to a primary combustion section 6 and ignited by an ignitor 7 to form flames. When an oxidizing and catalytic layer 8 has reached the temperature sufficiently high to carry out a catalytic combustion, a pump 2 is stopped to extinguish the flames at the primary combustion section 6. After this the pump 2 is actuated again to supply fuel and since there is an oxidizing and catalytic layer 8 which is at a sufficiently raised temperature stage at the primary combustion section, the catalytic combustion is started and complete combustion is achieved. Regarding the fuel and air supplied to the oxidizing and catalytic layer 8 at this time, the amount of air is supplied in an approximately constant amount and either only the amount of the supply air is varied to control the combustion amount or the control of the flow rates of the fuel and air by making the rate of decrease in the amount of the supply air smaller than the rate of decrease in the amount of the fuel supply is performed.

Title: Magnetic head device
Inventor: MIYAZAWA HIROSHI
IPC: G11B17/34
Filed: 1984-07-04
Abstract: PURPOSE:To obtain a stable reproducing signal by using a rotating body as a holder of a recording medium. CONSTITUTION:A holder 1 is positioned on a recording and reproducing gap of a magnetic head 2 and constituted so as to rotate in the direction along the scanning direction of a recording medium 3. As for a position of the rotating direction, when the recording medium is shaped like a disk, for instance, a floppy disk, it will do that it is constituted so as to become vertical to the radial direction. When the magnetic head is moved to the inside periphery or the outside periphery, the rotation of the recording medium can be approximated to a straight line when it has been seen from the holder, therefore, a special contrivance for the holder is not required. As for the material quality of the holder 1, when that of the material quality having elasticity, for instance, hard rubber or felt is used for the contact surface to the recording medium 3, the contact state of the magnetic head 2 and the recording medium 3 is better. In this way, since a frictional resistance of the holder is not generated, the recording medium is held by a sufficient force without exerting a bad influence such as an uneven rotation, etc., a high density recording can be executed, and a stable reproducing signal is obtained.

Title: Image forming device
Inventor: NAGASE YUKIO
IPC: G03G15/00
Filed: 1989-05-31
Abstract: PURPOSE:To obtain a stable picture of high quality by correcting an input picture signal at the time of switching exposure energy, and forming an image by a laser driving signal whose pulse width is modulated based on a corrected signal. CONSTITUTION:A sensor 26 detects the electrified potential of a photosensitive body 91, and a potential measuring unit 27 converts it into a digital signal to input it to the CPU of a control part 25. Humitidy and temperature are detected by sensors 98 and 99, respectively, and are given to the control part 25; a required potential contrast is calculated; a laser exposure quantity is determined; and the potential of a photosensitive drum is controlled. When a laser beam quantity is switched, the pulse width of picture data is corrected, and identical picture density is imparted to the picture information by using only an area with the satisfactory linearity of a light quantity. In large laser power, PWM adjustment is carried out, that is, light quantities 00H and FFH are set to desired pulse widths; video data 00H is corrected to 10H when the laser power is minimized with the PWM adjusted under the large power. In this constitution, even when a laser beam quantity is varied, a driving signal with an optimum pulse width can be applied, and thus, a stable picture of high quality can be formed.

Title: Ccd image sensing device
Inventor: KAWAGUCHI TOSHIHIKO
IPC: H04N5/359
Filed: 1989-05-31
Abstract: PURPOSE:To decrease the blooming and smearing of an image sensing device of this design and to improve performance by a method wherein an overflow drain is provided to the base and the side wall of a charge storing region excluding a part of a transfer region. CONSTITUTION:An overflow drain(OD) 31 formed of an N-type layer of a unit region 30 is provided not only to the base but also to all the side wall except its part opposed to a transfer region 14. A CCD image sensing device of this design is used applying a reverse bias voltage (a positive voltage to OD 31) between the OD 31 and a P-type region 12 through the intermediary of a lead- out electrode 32. Here, an N-type substrate 11 and the OD 31 are kept at the same potential. The conduction band energy difference between the OD 31 and the region 12 is E0 when a reverse bias is not applied, and the energy difference E1 grows large enough to satisfy a formula, E1=E0+V1, when a reverse bias voltage V1 is applied. Therefore, electrons or the like emitted from a charge storage region as excited can be taken away by absorbing them by the deep energy valley concerned, so that the unit region 30 is able to store only electrons excited by incident light without being affected by excited electrons from an external unit region.
