Title: Optical device
Inventor: SAKATA HAJIME
IPC: G02F1/1335
Filed: 1984-12-05
Abstract: PURPOSE:To form an optical device which has no dependency on wavelength and has a highly advanced function by constituting two optical members of which at least one consists of a refractive index variable medium so as to posses commonly a grating boundary face. CONSTITUTION:A trapezoidal grating is formed of a transparent optical member 2 and a transparent electrode 3' is provided to the grating surface. The refractive index variable medium 1 is disposed between the electrode 3' and a flat plate electrode 3 facing said electrode. The refractive index of the medium 1 is controlled by the electric field impressed between the electrodes 3 and 3'. The projection length for one period of the grating, i.e., the projection length of the side inclined with respect to the width l of the grating satisfies the equation. Each slope has consequently the projection area of 50% of the total projection area. The control of the diffracted light by the grating without depending on the wavelength of the incident light is thus made possible by controlling the refractive index of the medium 1.

A transparent support 1 of the head 4 is irradiated with light as indicated by an arrow B, whereby a photoconductive body 3 is made to be conductive, and is brought to the same potential as that of an earth 2a through a transparent conductive layer 2. Ions of a gas on the printing paper 6 brought to the photoconductive body 3 are deprived of electric charges, resulting in that an electrostatic latent image of characters or figures is formed on the printing paper 6. A toner 12 statically electrified in a polarity opposite to that of the paper 6 is separated from a magnet roll 14, and is adhered to the latent image 8. Heated rollers 15 apply heat to the paper 6, whereby the toner 12 is fixed.

Title: Fault processing system for loop type communication system
Inventor: YAHAGI MITSURU
IPC: H04L12/42
Filed: 1991-10-04
Abstract: PURPOSE:To prevent fault of a system caused by the fault of its own station by abandonning the master right of its own station when generating abnormality at the frame generating function of a control station, and preventing the master right from being acquired even in case of processing the reconstitution of a loop. CONSTITUTION:When abnormality is generated in the loop during the normal operation of a control station 1, the abnormality is monitored and it is judged whether the loop is abnormal or not. When it is judged that the loop is abnormal, the master right of its own station is abandonned and when being participated in the loop again, self-return diagnosis is executed. As the result, when abnormality is shown, a master right acquisition inhibit processing is executed. Next, when the loop reconstitution processing is executed and a master decision processing is started, the master right is prevented from being acquired even when its own station has the high priority as a master. Thus, the fault of the system caused by the fault of its own station can be prevented.

Abstract: PURPOSE:To reduce the generation of noise by varying at least a part of each of the positions of a stabilizer and a rear guider, and shifting the generating times of blade-pitch sounds, to disperse the timing of generating the blade-pitch sound and make said sounds interfere with one another. CONSTITUTION:One tongue part 2a of a stabilizer 2 is placed in a position S1 which is circumscribed about a circle centering around the shaft center O of an impeller 1 while passing through a point P1 apart from the outside diameter of the impeller 1 by a dimension S. Another tongue part 2b of the stabilizer 2 is placed in a position S2 circumscribed about the same circle at a point P2, being shifted in the axial direction of the impeller 1. Further, the parts of a rear guider 3 which are opposite to said tongue parts 2a, 2b, are equally placed in positions t1, t2, being rotated in the same directions and by the same angle Q as the tongue parts 2a, 2b centering around the shaft center O of the impeller 1 respectively. Thereby, varied sound pressures near the stabilizer 2 mutually offset and are reduced, thereby, reducing a blade-pitch sound. Furthermore, a peculiar rolling sound of rotation resulting from the rotating frequency of a fan, can also be prevented.

Title: Wire electric discharge machine
Inventor: SHINKAI MASARU
IPC: B23H7/02
Filed: 1986-10-31
Abstract: PURPOSE:To keep off any defective in accuracy of finishing due to deformation of a lower arm, by stopping electric discharge machining operation when a fact that the workpiece dropped on a work tank comes into contact with a conductive detecting tube is detected by a contact detecting device. CONSTITUTION:In the case where scrap of the workpiece 12 machined for EDM by a wire electrode 10 is dropped on a work tank 16 and comes into contact with a conductive detecting tube 40, the work tank 16 and this conductive detecting tube 40 are electrically conducted to each other, and when it is detected by a contact detecting device 42, electric discharge machining operation is stopped.

Title: Field effect transistor circuit
Inventor: MATSUURA SOHEI
IPC: H01L27/06
Filed: 1988-10-13
Abstract: PURPOSE:To prevent lowering of signal amplification characteristic, electrostatic breakdown strength characteristic, etc., by designing a breakdown voltage of a first and a second gate protecting diodes different from each other. CONSTITUTION:When a breakdown voltage of a protecting diode of a gate terminal of a field effective transistor circuit is designed, a second gate protecting diode 14 is designed to 10V as a lower limit value and a first gate protecting diode 15 is designed to several V or below as an upper limit value. Since AGC (automatic gain control) signal is applied to a second gate AGC input terminal 2 from an IF circuit of a TV receiver circuit, etc., a breakdown voltage of the protecting diode 14 requires a breakdown strength of at least 10V. A first gate signal input terminal 1 is about 100dBmuV at an upper limit as an input signal level. However, for instance, when it is connected to an antenna terminal of a TV receiver circuit, a transient surge voltage such as a ground discharge surge is applied from an antenna; therefore, it is desirable to make a breakdown voltage of the protecting diode 15 not exceeding several V considering electrostatic breakdown strength.
