Abstract: An electroconductive paste that contains an Ag powder, glass frit and an organic vehicle. The glass frit is of non-lead type and contains at least B, Bi and Si and the molar ratio of B to Si is 0.4 or less, and the molar content of Bi in the glass frit is 20 to 30 mol %, and a D90 diameter of the glass frits is 5 ?m or less. A light-receiving surface electrode is formed using this electroconductive paste on a surface of a semiconductor substrate to form a solar cell.

Abstract: An automotive wheel that can prevent deformation of a back side opening edge of a wheel rim in a radial direction and reduce the weight of the wheel rim is proposed. Because the automotive wheel has a structure in which an annular rib section formed in a stepped manner at each of the inside and the outside and having a thinner wall thickness than the other part of a ledge section is circumferentially formed in the ledge section of the wheel rim, an effect of preventing the deformation of a back side opening edge of the wheel rim in a radial direction is improved by virtue of a shaping effect of the annular rib section, and a weight reduction effect can be provided in connection with the thinner wall thickness of the annular rib section.

Abstract: Provided is a film formation apparatus capable of reducing vibration and deformation that may be transmitted to an alignment mechanism and thereby suppressing misalignment between a substrate and a mask in a surface direction. The film formation apparatus includes: a film forming chamber; a supporting member; and an alignment mechanism provided on the supporting member in which: the supporting member includes a supporting plate for placing the alignment mechanism, and a leg portion; the supporting plate is provided so as to be spaced apart from a top board of the film forming chamber via the leg portion; and at least a part of the supporting plate is formed of a damping material capable of converting vibration transmitted to the supporting plate into thermal energy, thereby suppressing the vibration.

Abstract: Ag electrode paste for forming a light-reception-surface-side electrode, with which a solar battery cell having a light-reception-surface-side electrode low in line resistance and achieving high conversion efficiency can be obtained, a solar battery cell having good characteristics manufactured therewith, and a method of manufacturing the same are provided. A silver electrode paste contains (a) Ag particles, (b) an organic vehicle, and (c) lead-free glass fit containing 13 to 17 weight % SiO2, 0 to 6 weight % B2O3, 65 to 75 weight % Bi2O3, 5 weight % Al2O3, 1 to 3 weight % TiO2, and 0.5 to 2 weight % CuO is employed as a Ag electrode paste used for forming a light-reception-surface-side electrode. A Ag electrode paste is used for forming a second electrode of the light-reception-surface-side electrode which includes a first electrode and the second electrode disposed on the first electrode.

Abstract: An electrically conductive paste which can be formed into an electrode by being fired at relatively low temperatures, which exhibits excellent adhesion strength between a light-receiving surface electrode and a semiconductor substrate, and which can satisfactorily reduce the contact resistance between the two, is provided. The electrically conductive paste used as a material for a light-receiving surface electrode of a solar cell, includes a Ag powder, an organic vehicle, and glass frit, wherein the softening point of the above-described glass frit is 570° C. 760° C., and the glass frit contains B2O3 and SiO2 in such a way that the ratio, B2O3/SiO2, becomes 0.3 or less on a molar ratio basis and the first contains 0 to less than 20.0 percent by mole of Bi2O3.

Abstract: Merchandise temperature sensors 16 for detecting merchandise temperatures simultaneously with in-housing temperature sensors 17 for detecting the in-housing air temperature of a merchandise housing are provided in the merchandise housing of a vending machine. Further, the cooling mechanism is controlled by means of the merchandise temperature sensor 16 during the peak shift or peak cut, whereas the cooling mechanism is controlled by means of in-housing temperature sensor 17 during normal operation. Thus the merchandise temperature is directly detected during the peak shift or peak cut where the temperature sharply varies so as to increase merchandise temperature control accuracy. Even when the installation of the merchandise temperature sensors is limited to some columns in view of cost reduction, the cooling mechanism is made controllable by collectively detecting the merchandise temperature in the whole column by means of the in-housing temperature sensors 17 during the normal operation.

Abstract: A rear projection type television unit comprises a television body having an outer casing in which electric and optical parts are accommodated and a front panel detachably attached to a front portion of the television body so as to entirely cover the front portion thereof. The television of the structure described above is accommodated in a wall structure of a chamber so that the front surface of the front panel lies on the same level as that of a front surface of the wall structure when the television body is accommodated in a wall structure. The television unit is safely and stably supported in the recessed portion formed in the wall structure by support members such as angle members secured to the side portions of the television body by engaging the same with support members secured to the wall structure.

Abstract: Enclosed switching apparatus has a tank, a circuit breaker, a pair of contact pedestals provided on both sides of the circuit breaker, and a disconnecting switch. The tank is provided with a lead-out portion extending in a direction perpendicular to the axis of the breaker and disposed adjacent to one of the contact pedestal. The disconnecting switch is at least partially disposed in the lead-out portion, with the axis of the disconnecting switch being coincident with the axis of the lead-out portion. An operating device is provided for operation of the movable contact of the disconnecting switch. A drive bar member couples the movable contact to the operating device, extends through the tank along a line of extension of the axis of the disconnecting switch and includes a conductor portion electrically connected to the movable contact. A slide contact is mounted on the above-mentioned one of the contact pedestals to slidably receive the conductor portion of the drive bar member.
