Patent JP-S58164918-A (JP)
Title: Liquid-firing combustion apparatus for liquefied petroleum gas
Inventor: ETOU TASABUROU
IPC: F23D11/00
Filed: 1982-03-23
Abstract: PURPOSE:To eliminate the need for a carburetor particularly, to make the cost profitable, to improve an effective utilization rate, to economize energy and to reduce cost  by arbitrarily regulating the orifice of the discharge section of a burner in response to  the quantity of combustion, atomizing LPG at above a vaporization pressure at all  times and preventing vaporization in the burner. CONSTITUTION:LPG supplied from a connecting port 1 is forwarded to a variable orifice section A through a clearance 5 between a stem 3 penetrating the center of a housing 2 and an inner pipe 4. The variable orifice section A has a non-return needle valve, and is constituted by a piston orifice fixed at the nose of the stem 3 and a fixed  cylinder nozzle 8 surrounding the outer circumference of the piston orifice. When the stem 3 is moved in the axial direction, a discharge area changes. That is, the most pointed end of the cylinder nozzle 8 is a minimum section of a pass area in an LPG gas path because the pass area is narrowed with the forward progress of the nose of the piston orifice 7, and LPG is ejected into a furnace from the section. LPG ejected is atomized rapidly due to a pressure drop by discharge into auxiliary air or atmospheric air, and burnt by mixing with secondary air.

Abstract: PURPOSE:To allow the main inspections and the adjustment of a lens barrel inside without removing a front cover by providing the separated part of the lens barrel, which is projected more than a camera main body so as to surround a photographing lens, at the rear position of the photographing lens projected part. CONSTITUTION:A ring 3 provided with plural flexible engaging clicks 3A on the rear end plane fitted in a front barrel 2A are incorporated to the inner circumference plane of the front barrel 2A by adhesion after dropping a waterproof filter 4 on the front end plane and inserting O ring 5 in the circumference of the waterproof filter 4 with pressure so as to permit watertight condition. In this case, when the front barrel 2A pushes and deforms the circumferential part of the front barrel 2A which is equivalent to the engaging clicks 3A, the engaging clicks 3A elastically deforms to the inside, and when pulled out in the optical axis direction, the engagement with the front cover 1A is released and are separated. Thus, the inspection and part replacement such as adjustment in a lens barrel 2 are easily carried out.

Title: Apparatus and method for examining electron emissive element
Inventor: NISHIUMA SATOSHI
IPC: H01J9/02
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To examine the electron emission characteristic of an element through detection of the electrons emitted by applying the voltage to a matrix element on a board loaded on a chamber, from which the air is exhausted before the sealing of an electron source panel of a display device, and judging the quality of the electron emission characteristic. SOLUTION: The low drive voltage for examination is continuously and successively applied to the surface conductive type electron emissive elements arranged in matrix shape on an electron source panel 1 in an inspection chamber 8, which is evacuated by a turbomolecular pump 2B, a rotary pump 3 and the like, and electrons are emitted. The difference between numerical quantities obtained by counting the electrons detected by a grid-shaped E-T detector 4 comprising a scintillator, a photomultiplier and an electrode by measuring circuit 5, and the prescribed threshold is compared with a prescribed reference value to examine the electron emission characteristic. The emission current is recorded by a recording device 6. Since the exhausting is evacuated down to 10-6-10-7 Torr, driving is preferably executed at a voltage of 6-6.5 V, whereby the deterioration of the element can be reduced.  An electric field emission type cold- cathode element may also be used.

Abstract: PURPOSE:To reduce indoor contamination due to combustion gas even when combustion is stopped by abnormal condition by a method wherein the combustion of a burner is stopped and post purge is carried out when the continuing time of combustion has exceeded a set time. CONSTITUTION:A control unit H counts the continuing time of combustion of a burner 2 by a counting means 102 and when the continuing time of combustion has exceeded a set time, it is judged that the condition of the device is abnormal due to forgetting of closing operation of a hot-water supplying cock or the like. Then, the flashing of an abnormality indicating LED lamp 16 is effected and an operation locking means 103 is operated to make operation command, effected by an operating unit R, impossible. Next, the control unit H sets the operating time of post purge effected after stopping combustion and stops the supply of fuel to the burner 2 to stop the combustion of the burner 2 and, thereafter, post purge is carried out until the previously set time has elapsed under a condition that the amount of ventilation of a fan 4 is maximized.

Title: Minor load sensing device of induction heater
Inventor: MIZUKAWA TAKUMI
IPC: H05B6/12
Filed: 1978-04-17
Abstract: PURPOSE:To sense off minor load by the use of an integral circuit which spares as direct energy the differential wave form of electric charges discharged from the resonance capacitor in another capacitor and checks the outflow of it with a zener diode. CONSTITUTION:When a load 9 is too small for the heating coil 8, the equivalent effective resistance of the load becomes small, so that the damping quantity is very small even though voltage of the resonance capacitor 7 is actuated into oscillation when the thyristor 3 is turned on. Accordingly, the initial value of the voltage generated between the two ends of the thyristor 3 when the thyristor 3 is turned off, becomes high, so that projection voltage is generated through the resonance of the heating coil 8 and the snubber capacitor 5. The rising voltage at the initial period of charging of the capacitor 7 or the signal obtained through a differential process of the voltage between the snubber resistor 6 is stored in the capacitor 13. Zenor diodes 11, 12 prevent the differential electric charges stored in the capacitor 13 from discharging. The reference signal and the electric charges discharged from the capacitor 13 are put into the comparator 17 to make possible sensing off any minor load at a sunken power level.

Title: Temperature estimator of exhaust system parts for internal combustion engine
Inventor: HOSHI KOICHI
IPC: F02D45/00
Filed: 1988-02-29
Abstract: PURPOSE:To estimate a temperature rise in an air-fuel ratio sensor in a highly accurate manner by compensating an increase time, when the integrating value of a compensation value conformed to an intake air quantity is increased up to the specified value, for prolongation according to an outside temperature drop, at time of estimating a temperature change in exhaust system parts. CONSTITUTION:A compensation value being set according to an intake air quantity of an internal combustion engine M1 detected by a detecting means M2 is integrated with time elapse by an integrating means M3, and when this integrated value is more than the specified value, it is so estimated that temperature in exhaust system parts (an air-fuel sensor or the like) M4 goes up, and when it is less than the specified value, the temperature goes down, respectively, by an estimating means M5. At this time, with the drop of outside temperature detected by a temperature detecting means M6, compensation of either decrease compensation of the integrated value or increase compensation of the specified value of the estimating means M5 is carried out by a compensating means M7. Thus, whether a temperature rise in the air-fuel ratio sensor, namely, it is in an active state or not is accurately detected without being affected by a variation in the outside temperature, and thus the promotion of high accuracy in air-fuel ratio feedback control is contrivable.
