Title: Sliding member of spontaneous lubricant forming type and its production
IPC: G21C5/00
Filed: 1992-03-16
Abstract: PURPOSE:To provide the wear resistant sliding member which is a sliding member to be used in a liquid sodium environment and spontaneously forms a lubricant in sodium. CONSTITUTION:This sliding member is constituted of a base body 1 which consists of a stainless metallic material, a coating layer 2 which is formed on the surface thereof and consists of a chromium carbide having pores 5 and chromium oxide which is impregnated in these pores 5. The chromium oxide in the pores 5 forms the lubricant NaCrO2 by reacting with the sodium in the liquid sodium. This lubricant can be continuously supplied to a sliding surface, by which the galling of the sliding member is prevented. In addition, friction resistance and wear characteristics are improved and a longer life is obtd. The reliability of the equipment to be used in the Na liquid is greatly improved.

Title: Initial-offset setting method for oscillator in gps receiver
IPC: G01S19/23
Filed: 1992-03-16
Abstract: PURPOSE:To shorten the capturing time of a satellite by regarding the change in offset value of an oscillator as the function of the elapsed time from the OFF time of the power supply of a GPS receiver, and utilizing the offset value at the previous position measuring time. CONSTITUTION:When the power supply of a GPS receiver is turned OFF, the offset value of the oscillator is stored in a memory, and an internal clock starts the counting of time. When the power supply is turned ON, the OFF time from the previous position-measuring time is detected. For example, whether 30 minutes are exceeded or not is judged. When the OFF time is less than 30 minutes, the width is set narrowly with an initial-search band width Wo as the function of the OFF time. A central frequency for searching is obtained as the sum of a Doppler-frequency shift DELTAfd and a stored offset value fosc. With the fs as the center, the searching is performed by the up and down scanning at the width of Wo. When the satellite cannot be captured, the searching width is gradually expanded. When the OFF time exceeds 30 minutes, the initial searching width Wo is expanded to the entire range of the offset fluctuation, and the previous offset value is not used for the computation of the central frequency fs.

Abstract: PURPOSE:To shorten a repeated processing time by writing the request and the condition of a digital data in a 2-port memory, and executing a repeated processing by a function unit control program, when the condition is satisfied. CONSTITUTION:A digital data converted by an A/D converter 9 is written in a buffer memory 7, and a main control program writes a buffer memory read- out request in the 2-port memory 4. As a result, the processing is shifted to a function unit control program, and when a condition deciding processing is requested, a read-out request signal is outputted to a CPU 6 for an a/D conversion. As a result, the processing is shifted to an A/D conversion control program and when the request signal is effective and the conversion processing is completed, a completing signal is outputted to a CPU 3 for a function unit control. Subsequently, the data is read out of the memory 7, and when a prescribed condition is formed, a completion code is written in the memory 4 and the processing proceeds to the next processing in a main control program, therefore, the repeated processing time is shortened.

Filed: 1981-04-17
Abstract: PURPOSE:To prevent generation of fog, etc., by constituting a developer of mainly grains whose grain diameter is larger than height of a projection provided on the surface of a dielectric layer of an electrostatic recording medium. CONSTITUTION:A developer 3 removed from an electrostatic recording medium 1 drops into a developer receiver 12, is returned to a developing device 9 through a developer return flow pipe 13 from said receiver, and is used again. Also, as for the part from which a developer 3 has been removed by a blade 4 in the electrostatic recording medium 1, subsequently, an electrostatic latent image is removed by a destaticizer 14, and after that, a new electrostatic latent image is formed again by a recording head 7, and subsequently, such a process is repeated. Since the developer 3 is constituted of mainly grains whose grain diameter (d) is larger than height (h) of a projection 2, even after it has slide- contacted with the blade 4, the grains of the developer 3 are scarcely left in the circumference of the projection 2 on the surface of a dielectric layer of the electrostatic recording medium 1, therefore, generation of abnormal recording such as fog, etc. is prevented.

Abstract: PURPOSE:To improve the electrophotographic characteristics of a separated function type sensitive body and to provide superior durability by forming a cured film consisting of specified melamine resin and polyvinyl acetal resin as the protective layer of the sensitive body. CONSTITUTION:When a sensitive body is produced by successively forming an electrically conductive layer, a charge generating layer, a charge transferring layer and a protective layer, a cured film consisting of butyl-etherified melamine- formaldehyde resin having <=1,500 number average mol. wt. and polyvinyl acetal resin is formed as the protective layer. The melamine resin has 2-4 formaldehyde groups and 1-2 methylol groups bonded to each melamine ring. Since the melamine resin can be cured at a lower temp. than conventional melamine resin, the sensitive body is not thermally deteriorated during the formation of the protective layer, and the wear resistance of the sensitive body can be improved. The protective layer having the advantages can be made thin and tough by combining the melamine resin with the acetal resin. Thus, the sensitive body is protected without deteriorating the electrophotographic characteristics, and a sensitive body having high sensitivity and superior durability can be obtd.
