Abstract: PROBLEM TO BE SOLVED: To readily obtain the subject compound useful as a synthetic raw material for medicines, especially antithrombotic agents and having high optical purity by reacting a readily available meso compound used as a raw material with a phenolic derivative and an optically active additive. SOLUTION: (A) A meso compound of formula I [R<1> is an acyl, an alloyl, an alkyl, an aryl, etc.; (n) is 0-4] is reacted with (B) a phenolic derivative and (C) an optically active additive (preferably phosphorous compound) to provide (D) the objective cycloalkene derivative of formula II (A, B and E are each independently H, a halogen, an alkyl, an aryl, etc.). The component D is further converted to a phenoxycycloalkene derivative by reactions such as hydrolysis reaction and Koen reaction and the derivative is subjected to cyclic reaction by using a metal-or an organic metal reagent. The derivative can readily be induced to a cycloalkyl[b]benzofuran of formula III (G and L are each independently H, a halogen, etc.), by the above reactions. Thereby, the objective product can be provided by using a simple organic synthetic technique.

Filed: 1987-03-11
Abstract: PURPOSE:To improve photoelectric conversion efficiency by providing, on a conductive substrate, a lowest layer pin element and a surface layer pin element having a window for light input thereon and providing a power collecting transparent conductive film between both pin layers. CONSTITUTION:The lowest layer pin element 2 mainly formed by the amorphous silicon alloy and a surface layer pin element 3 which is formed on such element 2 and formed mainly by the amorphous alloy having a window for light input are formed on a conductive substrate 1. A transparent conductive film 7 is formed on the entire surface of the lowest layer pin element 2 between the lowest layer pin element 2 and the surface layer pin element 3.

Title: Method and device for processing graphic
Inventor: NAITO AKIRA
IPC: G06T15/20
Filed: 1989-03-10
Abstract: PURPOSE:To improve operability and expand a function by setting a viewpoint, a nearest point, a dissipation point, a projected surface position, and preparing a grid based on perspective drawing. CONSTITUTION:When the viewpoint is positioned in a (z) direction with respect to a point 202, the point 202 is set at the nearest point, a distance between the viewpoint and the nearest point 202 is set at (b), and a visual limit point 203 called as the dissipation point is set remote in an (x) direction of the orthogonal grid. From a viewpoint 204, a graphic 201 on the orthogonal grid appears as if it is projected on a projected surface 205 at a distance (a) from the viewpoint 204, and the position of the graphic 201 on the projected surface 205 can be obtained by the intersection between a straight line 206 connecting the viewpoint 204 and the graphic 201 and the projected surface 205. Further the value of Xn for the dissipation point (the intersection between a straight line 209 linking the viewpoint 204 and the dissipation point 203 and the projected surface 205) is approximated when it is equivalent to (b) and the value of Yn for the dissipation point is approximated when it is equivalent to zero. Thus by changing a height (h) of the graphic 201 corresponding to the (x) directional grid of the orthogonal grid, a projected image can be obtained, and the grid can be prepared.

Title: Induction motor starting system by variable frequency power source
Inventor: SAKOU SHIYOUJI
IPC: H02P1/26
Filed: 1979-05-09
Abstract: PURPOSE:To facilitate low-frequency starting of an induction motor, by increasing a starting torque current ratio. CONSTITUTION:A switch 23 is turned on to allow a starting current reference signal 21 to issue a command to pass to a rectifier 2 a current suitable for the current reference signal. Since a current loop has quick response, a motor current reaches a commanded value rapidly. At this time, a torque generated between an excess DC component induced to a rotor and a rotating magnetic field is duplicated by a constant DC torque of a power source frequency component whereby a starting torque 7 becomes increased. After a prescribed time elapsed, the switch 23 is turned off and a switch 22 is turned on for switchover of control to voltage reference control. And then, when a switch 16 is turned on, an inclination signal generating circuit output 18 rises at a prescribed speed, and when an output 19 of a pattern circuit 13 exceeded a starting voltage reference voltage, a diode 26 becomes turned on and a diode 25 becomes turned off, and therefore, a motor 7 becomes to have its voltage controlled by the pattern output 19.

Abstract: PURPOSE:To obtain an insulating sheet for an armature which has high insulation and can effectively facilitate a connector of a band section by providing the connector having at an oblique angle at the opposed side on the center line of a crescentlike recess. CONSTITUTION:When a band 6 is pulled up by a suitable force in a direction of an arrow C, an insulating sheet 4 rides on an auxiliary coil 3 which substantially becomes a top, its component force acts in a direction of an arrow D, and it does not drop radially of a coil end. Then, a protrusion 53 is inserted into a connector 51, and pulled and penetrated until a connector 52 is engaged. The band 6 is applied by an elastic force tending to unwind itself, a force for correcting the displacement of the positions of the connectors 51, 52 and the elastic force of a bundled coils to become a returning force, but since it acts at the inclined connector, it intrudes into the deep section, thereby effectively connecting it.
