Title: Room temperature display device of air conditioner
Inventor: ISHIKURA NAOKI
IPC: F24F11/02
Filed: 1984-07-05
Abstract: PURPOSE:To make it possible to display a set room temperature selected and a room temperature monitoring temperature at the time point of using on a room temperature display light emitter by causing one of a plurality of light emitters provided in parallel to constantly emit light and another to flicker. CONSTITUTION:At the right upper part of a main body case 1 is provided an operating part 2 which input-controls the combustion of a burner. On the lower back surface thereof is provided a heat sensing part 7 of a room thermostat which senses the room temperature, and the room temperature is displayed by a series of light emitters 5 based on the signal from the heat sensing part 7. Upon this occasion, only one light emitter flickeringly emits light in accordance with the set value. The set temperature which has been selected by a temperature adjusting button 4 of the operating part 2 is controlled so that one light emitter corresponding to the set value constantly emits light. Further, every time the adjusting button 4 is pushed, light emission is gradually transferred from the left- hand light emitter 5, and when light emission is transferred up to the light emitter 5 at the rightmost end, it returns back again to the left hand light emitter 5. Thus, the light emitter 5 indicating the set room temperature is caused to constantly emit light, and by only observing the right side or the left side or the upper and lower sides of lamps of the light emitter which flickeringly emits light by monitoring the room temperature at that time point, it can be easily discriminated whether the room temperature is higher or lower than the set room temperature.

Title: Gas metal arc welding method for extra low carbon steel
Inventor: MORI NAOMICHI
IPC: B23K9/173
Filed: 1981-09-08
Abstract: PURPOSE:To prevent the high temp. cracking of welded metal in welding of extra low C steel by using a high C solid wire of a specific content of C and specifying the content of C of the deposited metal in the 1st layer by a specific equation. CONSTITUTION:The relations between the content of C in weld metal and the rate of X-ray cracking are as shown in the figure which reveals that high temp. cracking arises in a region B other than a region A. The possible cause for said generation lies in that the dendrite butt layer causes delta solidification. An increase in the content of C which is an element for delta stabilization is required to decrease the cracks. Therefore the target steel contains 0.005-0.06% C, and the steels contg. gamma former elements such as Ni are excluded. The rate beta of dilution of welding base materials varies with welding conditions and is confirmed to be about 40-50% in the groove. The content of C, CWM(%) at which no high temp. cracking of weld metal arises is given by the equation (alpha: yield rate of C, CP, CW: the contents of C of steel materials and wires (%)). To this end, the CW is decreased or increased by increasing or decreasing the content of C in the target steel and a wire contg. 0.09-0.33% CW is used.

Title: Limit current type oxygen sensor
Inventor: ASANO YOSHIHIKO
IPC: G01N27/41
Filed: 1990-05-30
Abstract: PURPOSE:To obtain an oxygen electrode easy to mold, operated even at low temp. and adjustable in its current/voltage characteristics corresponding to a use state by forming a solid electrolyte into an LaF3 single crystal and forming an oxygen gas rate limiting body into porous stainless steel. CONSTITUTION:By using an LaF3 single crystal 1 as a solid electrolyte, this oxygen sensor can be operated at low temp. and the characteristics thereof are not changed at the time of molding. Since an oxygen gas rate limiting body is formed using porous stainless steel, a moving oxygen amount is limited. Therefore, even when voltage is made high in current/voltage characteristics, a section where current quantity becomes a constant value is generated. As a result, the characteristics of the oxygen sensor can be adjusted by increasing and decreasing the moving oxygen amount by changing the pore size of porous stainless steel.
