Title: Production of alcohol compound by elimination of protecting group
Inventor: ODERA JUNZO
IPC: C07C33/02
Filed: 1987-04-08
Abstract: PURPOSE:To obtain an alcohol compound in high yield, by treating an alcohol compound containing a hydroxyl group protected with a tetrahydropyranyl group with an organotin compound in the presence of Lewis acid catalyst and a solvent under a mild condition. CONSTITUTION:A compound shown by formula I (R is organic group) is treated with a compound [e.g. dimethylbis(methylthio)tin] shown by formula II [R<1> is alkyl or phenyl; R<2> is alkyl, aryl or aralkyl; (a) is 2 or 3] in the presence of Lewis acid catalyst (e.g. boron trifluoride etherate) and a solvent (e.g. toluene) and stirred for several hours at low temperature to give a compound shown by formula III. By the above-mentioned method, even if another protecting group and an alpha,beta-unsaturated double bond exist in the same molecule, a tetrahydropyranyl group can be eliminated without exerting influence on the protecting group and steric isomerism and OH group can be reformed and especially a natural substance is advantageously synthesized.

Title: Method of printing metallic paste for thick film conductor
Inventor: NARUSE MASATO
IPC: C09D11/00
Filed: 1989-04-07
Abstract: PURPOSE:To control the thickness of a conductor layer to the specified thickness so as to obtain a specified resistance value by printing metallic paste for thick film conductor formation, which has the specified values for both values of viscosity and thixotropy index, on a green sheet. CONSTITUTION:The printing is done using metallic paste for thick film conduc tor formation which has such viscosity as to meet the relation of y=133t-660 at 0.924 for correlation coefficient, when the thixotropy index of metallic paste for thick film conductor formation to be printed on the surface of a green sheet is put in the range of 7-11, and thixotropy index is defined as t and the viscosity of metallic paste for thick film conductor formation is defined as y. Hereupon, if the thixotropy index is under 7, conductor thickness is not more than the specified value, which is too thin, and if it is over 11, the paste is too hard, with which printing property deteriorates. Hereby, desired values of conductor layer thickness and conductor layer resistance can be obtained.

Title: Recovering method of residual toner
Inventor: NAKAYAMA SHIGERU
IPC: G03G21/10
Filed: 1983-05-21
Abstract: PURPOSE:To facilitate the recovery of residual toner by setting the spacing position of a cleaning blade on an electrostatic charge holding member outside of an electrostatic latent image formation area corresponing to a copying form, and inhibiting the electrostatic discharging of a transfer corona electrostatic charger at least at the part including the spacing position. CONSTITUTION:A blade 21 is brought into contact with a photosensitive drum 1 with a copy start signal to start cleaning operation, and the corona electrostatic charger 3 is turned on to form an electrostatic latent image on the photosensitive drum 1. The corona electrostatic charger 3 is turned off with a latent image formation end signal. A corona electrostatic charger 13 for transfer turns on with the copy start signal and turns off after the period wherein the rear end of each electrostatic latent image passes from when the latent image formation end signal is generated. Further, the blade 21 is separated from the photosensitive drum 1 after the elapsed period wherein the position of the photosensitive drum 1 facing the electrostatic charger 13 reaches the blade 21. Consequently, residual toner is not charged electrostatically by neither the corona electrostatic charger 13 for transfer nor the corona elelctrostatic charger 3, so it is collected in a developing device 8 easily.

Abstract: The invention is a process for the manufacture of shaped articles of reaction-bonded silicon nitride in which pre-shaped articles of silicon powder are heated in a first stage under a nitrogen gas pressure of at least 6 MPa at a heating rate of not more than 50 DEG C. per hour to a reaction temperature below the melting point of silicon, the article is maintained at the reaction temperature for at least 0.5 hours and subsequently, in a second stage, heating the article at a heating rate of at least 500 DEG  C. per hour to a temperature above the melting point of silicon and maintaining the article at that temperature for from 1 to 7 hours. The process can nitridate both pre-shaped articles consisting of silicon powder and, optionally, up to 15% by weight Si3N4 powder and those containing up to 10% by weight of a sintering aid such as Y2O3. In the former case, porous shaped articles having a density of from 87 to 91% TD and, in the latter case, dense shaped articles having a density of more than 98% TD, are obtained. In all cases, in a total nitridation time of less than 15 hours, a conversion of at least 95% of the silicon originally present into silicon nitride is achieved, which, in the finished shaped article, is substantially in the  beta -modification.

Title: Ignition timing controller for internal-combustion engine
Inventor: FUJIWARA HIROHIKO
IPC: F02P5/10
Filed: 1983-05-23
Abstract: PURPOSE:To reduce the number of revolution in time of a maximum output without entailing any drop in output at a low speed range as well as to aim at a reduction in noise and a significant improvement in the durability of an engine, by detecting the specified engine speed, while controlling the ignition timing for spark delaying. CONSTITUTION:An output sensor 16 in a detection device 12 judges that, for example, the throttle valve of a carburetor operates in a full-open state and the output is maximum, and transmits its output to a speed sensor 14 which is therefore operated. And, when the number of engine revolution goes up beyond the specified engine speed, the speed sensor 14 detect it, transmitting the detection signal to a delay circuit 8 which is therefore set in motion. As a result, the signal fed to an igniter part 10 from a sensor part 6 by way of the delay circuit 8 comes into being delayed for a set time long. And, with the ignition timing delayed for the set time long like this, the apparent ignition timing is delayed to some extent in proportion as the engine speed increases, so that the output and speed of an engine will get lowering.
