Title: Combustion control device
Inventor: MATSUMOTO TOMOHIDE
IPC: F23N1/02
Filed: 1981-11-13
Abstract: PURPOSE:To provide always a stable combustion by a method wherein a sensor for sensing a volume of air supplied and a sensor for sensing a volume of gas supplied are arranged in each of the passages in the a pre-mixture type gas combustion control device and the volume of gas supplied is controlled in response to a rate of excessive air calculated in reference to these outputs. CONSTITUTION:When the control device is applied to the water heater, a water pressure reaponsive switch (not shown) is operated in response to an opening of the water faucet during its application, and then an air blower 1, a main solenoid valve 7, pressure proportional control valve 8 are operated in sequence. The pre-mixing burner 4 initiates a combustion to heat the water through the heat exchanger 19. In this case, the number of rotation of the blower 1 is controlled by the air flow rate control unit 22 in response to an output of the hot water temperature sensor 20. Output signals from the air pressure sensor 21 and gas pressure sensor 23 for sensing a flow rate in response to a differential pressure are fed to the gas flow rate control unit 24 to calculate a rate of excessive air, a degree of opening of the pressure proportional control valve 8 is controlled in response to a result of comparison from the comparator 27 for comparing the calculated rate with the predetermined value so as to adjust the flow rate of gas.

Title: Printer
Inventor: ARAI TAKAFUMI
IPC: B41J2/01
Filed: 1989-07-15
Abstract: PURPOSE:To conduct a teaching simply and correctly by a method wherein an indication light projection part emitting an indication light for indicating a position to which an ink is to be sprayed is provided on a head of an ink jet printer. CONSTITUTION:In a teaching operation, a printed wiring board serving as a body to be printed 1 is loaded, and an indication light is projected from an indication light projection part D provided on a head 2 correspondingly to a position to which an ink is to be sprayed. While the projection is visually identified, the teaching operation is conducted, such as a transverse-direction teaching, a longitudinal-direction teaching, and a teaching of a rotational angle of the head 2. After the completion of the teaching, printing is applied to the body to be printed 1. In this manner, the teaching can be conducted while a printing position for printing the body to be printed is determined based on an indication using a light. Thus, the teaching can be simply carried out without the need for teaching with an actual printing action.

Title: Centrifugal fan
Inventor: AIBAA UIRIAMU BORUTON
IPC: F04D29/42
Filed: 1990-07-12
Abstract: PURPOSE: To provide a silent centrifugal fan by substantially eliminating a flat part by specifying a route to guide air driven by an impeller to an outlet and shortening a scroll at a position of the outlet. CONSTITUTION: A temporary route is constituted so that air driven by an impeller 60 reaches an outlet by a wall part by mounting a motor 50 on a scroll 70, specifying an inlet and the outlet of air on this scroll 70 and including the outside wall part bent around the impeller 60. Thereafter, the scroll 70 is chamfered around its outlet part, and a flat part of the outside wall part generating mechanical vibration at informally decided frequency to be excited by the DC motor 50 is eliminated. In this way, it is possible to reduce the number of modes of vibration and amplitude at low frequency to be excited by the DC motor 50 and to reduce generation of noise by eliminating a flat radial surface on the outlet of the scroll 70 and remaining only a bent part.

Title: Method and device for induction-hardening crankshaft surface
Inventor: HATTORI HIROSHI
IPC: C21D9/30
Filed: 1988-07-21
Abstract: PURPOSE:To almost uniformize the depth of a hardened layer on the upper and lower sides of a part of a crankshaft to be heated by applying more current to the lower side than to the upper side by the amt. corresponding to the heat loss from the mass on the lower side. CONSTITUTION:When the pin 12 of a crankshaft 10 is at its highest position, the center 21 is situated at point C, and the shaft 10 is rotated. When the center 21 of the pin 12 comes to a specified point A, the protrusion of a limit switch actuating member is opposed almost to the front of a limit switch 651, hence the switch 651 is actuated, a high-frequency current is applied to a coil 30 by an oscillator 50, and hardening is started. The shaft 10 is further rotated by a specified number of revolutions, the center 21 reaches point B via the lowest point D, hence the protrusion of the limit switch actuating member is opposed to a limit switch 661, and the supply of current to the coil 30 by the oscillator 50 is stopped. Consequently, a current is not applied at the final rotation while the center 21 moves from point B to point A, more current is applied to the lower side of the pin 12 than to the upper side, and the depth of the upper and lower hardened layers is almost uniformized.

Title: Cultivation of euglena
Inventor: KITAOKA SHIYOUZABUROU
IPC: C12N1/10
Filed: 1982-10-18
Abstract: PURPOSE:To enable the mass cultivation of Euglena which assimilates fructose most easily among sacchrides, by culturing in a medium containing fructose-containing saccharide resource as a carbon source. CONSTITUTION:Euglena is devoid of an enzymatic system to assimilate monosaccharides and polysaccharides as carbon source, and has hitherto been cultured by using expensive ethanol, acetic acid, glutamic acid, etc. as carbon sources. A fructose-assimilable Euglena was obtained by separating Euglena glacilis 2K-14 strain from the field, and subjecting the strain to the adaptation to a fructose-containing medium. Accordingly, the strain can be cultured in a mass by using a fructose-containing sugar resource, such as the inexpensive carbon source by-produced from a sugar refining plant, e.g. black strap molasses, as the carbon source.
