Abstract: PROBLEM TO BE SOLVED: To obtain an air passage structure which can restrain a fine powder or the like from being mixed with a tire in a dynamic balance test by a method wherein an air passage which supplies the air to the tire sandwiched between, and held by, rims is formed so as to be isolated from the lock-shaft insertion part of a spindle. SOLUTION: A lock shaft 300 is inserted into a bracket 150 in a spindle 100, a cylinder 165 for locking is turned on, and a tire Tcan be sandwiched between, and held by, a rim 10 and a rim 20. The inside of a hollow part 115 in a spindle shaft 120 is used as a passage through which the inflating air is passed to the tire T, and the inner side of an air pipe 119 is used as a passage through which the air used to drive a cylinder 165 for locking is passed. In this manner, an air passage is arranged in a position in which a lock member 160 does not interfere with a sliding groove or the like. As a result, the air passage can be isolated from an environment in which a fine powder is easy to generate, and it is possible to restrain the fine powder from being mixed with the tire T.

Title: Solar cell
Inventor: ITOGA KAZUO
IPC: H01L31/0224
Filed: 1986-02-25
Abstract: PURPOSE:To obtain a solar cell of high performance having a large area of uneven shape efficiently manufactured and transparent electrodes made of low resistance transparent conductive film by employing as the transparent conductive film formed as a transparent electrode on a substrate of the cell a 2-layer structure of an impurity-undoped layer and an impurity-doped layer. CONSTITUTION:An impurity-undoped SiO2 film (undoped layer) 21 and an F- doped SnO2 film (doped layer) 22 for reducing a resistance are laminated on a transparent insulating substrate 1 made of glass or the like. Since crystalline grains of the undoped layer are high in a direction perpendicular to the substrate, the surface shows uneven shape. Since the grains become nucleus so that the crystal of the doped layer is grown, the surface of the layer 22 is formed in an uneven shape. Thus, the uneven shape which contains undoped layer is obtained to increase light scattering degree. Further, the uneven shape is controlled by altering the thickness of the undoped layer to increase the light scattering degree.

Title: Surface acoustic wave element
Inventor: KOJIMA HIROOMI
IPC: H03H9/145
Filed: 1991-03-06
Abstract: PURPOSE:To easily and accurately form a thin film stripe and to improve the characteristic of an SAW filter together with the electric power resistance properties secured. CONSTITUTION:A thin film stripe 2 is formed with an alloy of aluminum and palladium and therefore has the resistance almost equal to that of the pure aluminum owing to the palladium characteristic. Thus the minute palladium compounds are separated in the boundary of the crystal grains of aluminum. As a result, the movements of the aluminum particles are suppressed and then the occurrence of the hillock and the void are also suppressed. Thus it is possible to surely prevent the occurrence of the acoustic migration and also to increase the strength of an aluminum surface coat. Therefore a side etching phenomenon is surely prevented.

Title: Video signal transmission system for interphone equipment with monitor
Inventor: UENO YOSHIAKI
IPC: H04M9/00
Filed: 1988-02-24
Abstract: PURPOSE:To obtain a monitor video image with high quality without disturbing horizontal synchronization of the monitor video image even if a sag by a DC power supply separation means takes place by sending a high frequency burst signal at a higher frequency than the frequency band of the monitor video signal in place of a horizontal synchronizing signal of the monitor video signal so as to take the horizontal synchronization. CONSTITUTION:A high frequency burst signal VH' at higher band than the frequency band of the monitor video signal VP is sent from a video signal transmission section of an interphone slave set 1 in place of the horizontal synchronizing signal VH of the monitor video signal VP. Then the horizontal synchronizing signal VH'' is generated based on the high frequency burst signal VH' by the video signal reception section of the interphone master set 3 to display the monitor video image by the monitor video signal VP onto a monitor television set 4. Thus, even when the monitor video signal VP causing sag by the DC power supply separation means is received, the horizontal synchronizing signal VH'' generated based on the high frequency burst signal VH' is immune to the effect of sag. Thus, the horizontal synchronization of the monitor video image displayed on the monitor television set 4 is not disturbed.
