Title: Measuring apparatus for liquid level of capacitor in nitrogen generating apparatus
Inventor: YANAGII TOSHIAKI
IPC: F25J3/04
Filed: 1991-03-29
Abstract: PURPOSE:To correctly measure the liquid level by providing a blow-in conduit line of a product nitrogen gas at the high pressure side of a measuring conduit for taking out a differential pressure. CONSTITUTION:The pressure at the side of a capacitor 2 is made lower than that of a rectifying column 1 by an expansion turbine bypass valve 8 so as to lower the temperature of the capacitor 2. A product nitrogen gas with high pressure is blown into a high pressure measuring conduit of a capacitor liquid level gauge 4 through a needle valve 9 and a flowmeter 10. It becomes accordingly possible to blow the nitrogen gas into the high pressure measuring conduit of the liquid level gauge 4 without using a special equipment, and prevent the liquid level gauge 4 from erroneously operating because of the accumulation of impurities. The liquid level of the capacitor can be measured correctly.

Title: Piezoelectric oxide material
Inventor: YAMASHITA YOUHACHI
IPC: H01L41/187
Filed: 1979-05-30
Abstract: PURPOSE:To obtain a high-performance piezoelectric material by replacing a portion of Pb in PbTiO3-Pb(Me1/2W1/2)O3 (where Me is Mn or Zn) with Sr and adding one of MnO, NiO, and Fe2O3 if required. CONSTITUTION:In (1-x)PbTiO3-xPb(Me1/2W1/2)O3, Mn or Zn is used in Me, and the composition is adjusted such that 0.01<x<0.2. In the case x<0.01, the sintering property is poor. In the case x>0.2, the curie temperature is decreased below 400 deg.C, and the stablized utilization at the temperature exceeding 300 deg.C cannot be made. The utilization in the high-frequency region over the permittivity of 250 is not suitable. Then, Pb is replaced with Sr of 0.5-20 atomic %, the piezoelectric material can be readily polarized and sintered, and the utilization at the high temperatures becomes possible. Furthermore, if one of MnO, NiO and Fe2O3 of 0.05- 2wt% is added, the temperature characteristics, the time duration characteristics, and the mechnical quality factor of the PbTiO series ceramics are improved, and the large sontered bodies can be readily manufactured.

Title: Intermittent driving device
Inventor: MATSUDA SUNAO
IPC: F16H27/02
Filed: 1980-05-19
Abstract: PURPOSE: To set the intermittent time and the number of revolution of a shaft to be driven accurately by mounting pawl sections for pushing and movement to endless chains disposed in parallel.  
     CONSTITUTION: An endless chain 3 is arranged to a driving shaft 1 and an endless chain 7 to a shaft to be driven 5 in parallel shapes. Pawl sections 4 for drive are installed on the chain 3 at the drive side and pawl sections 8 also on the side to be driven, and the shaft to be driven 5 follows the continuous revolution of the driving shaft 1 intermittently. Intermittent time can be set arbitrarily according to the difference between the intervals of the pawl sections 4 at the driven side and a feeding distance per pitch of the pawl sections 8 at the side to be driven. Thus, the intermittent action of the endless chains is accurate and accumulative error is not formed by mounting the pawl sections moving the endless chains only by fixed distances to the endless chains.

Title: Automatic biochemical analyzer
Inventor: INEJI MINORU
IPC: G01N35/02
Filed: 1989-03-18
Abstract: PURPOSE:To obtain an effective data as early as possible by performing an analysis on a necessary sample alone continuously more than once. CONSTITUTION:Specimens 2001-200n are sampled from an sample 100 to be analyzed and the first specimen 2001 is distributed to an analysis means 400 by a specimen dispenser means 300 to perform a first analysis. Then, a judging means 500 inputs the results of the analysis, which are compared with a specified value to judge whether a reinspection or an analysis for another item is necessary or not. Then, when further analysis following its second is determined to be unnecessary, the analysis is finished. When it is determined to be necessary, the results of the judgment are inputted into a control means 600. The control means 600 applies a command signal to the analysis means 400 and the dispenser means 300 to let the subsequent specimen 2002 be distributed and a second analysis is performed. Thereafter, this loop is repeated to end the analysis. This can reduce a sampling to once only and only when necessary, analysis is performed on the same sample more than once continuously and automatically, thereby enabling the obtaining of an effective and definite data as early as possible.

Title: Electrode for spot welding
Inventor: KAMOSHITA KOICHI
IPC: B23K11/30
Filed: 1985-03-30
Abstract: PURPOSE:To prevent deformation and sticking of spatters and to obtain good welding quality for a long period of time by forming an iron plating layer on an outside surface including at least a pointed electrode end face which contacts under pressure with a member to be welded. CONSTITUTION:The iron plating layer 3 is formed to the pointed electrode end 2 of an electrode 1 for spot welding. If the thickness of the plating layer is excessively thin, the protective effect of the plating layer is not enough and therefore the plating layer is formed to >=5mum. The excessively thick plating layer leads to an increse in the calorific value in the plating layer and the plating layer is liable to peel and therefore the plating layer is preferably formed to <=50mum. The improvement in the durability is made possible by dispersing the pulverous particles of the metallic nitride and oxide such as alumina, silicon nitride and zirconia into the iron plating layer. The good welding quality is maintained for a long period of time by forming the iron plating layer having the small reactivity with zinc or tin in the above-mentioned manner.
