Title: Exhaust gas purification device for diesel engine
Inventor: SAKURAI SHIGERU
IPC: F01N3/025
Filed: 1982-07-22
Abstract: PURPOSE:To prevent dry grass or a passerby from being burned by a method wherein in the case of a device for preventing the clogging of a filter by operating a clogging removing means such as a burner, the operation of the clogging removing means is stopped when the vehicle is stopped. CONSTITUTION:When exhaust gases from the diesel engine 1 reaches the filter 4 and then passes through the latter through an exhaust passage 3, carbon particles in the exhaust gases are collected and removed. In case where the filter 4 is clogged, a clogging detector 6 generates an output by detecting the clogging of the filter from the lowering of the resistance value between electrodes 5a and 5b. Thus a fuel pump 13 and an air pump 14 are driven by the output of the clogging detector 6 through a control circuit 16 and the burner 7 is operated by turning an ignition switch 9 ON to thereby remove the clogging. Further, when an output is generated from a vehicle stop detector 15 during the clogging removing operation, the operation of the burner 7 is stopped so that no unfavorable phenomenon takes place due to the operation of the burner 7.

Title: Elevator controller
Inventor: ANDOU TAKEYOSHI
IPC: B66B5/02
Filed: 1977-10-27
Abstract: PURPOSE: To prevent an elevator from being accelerated drastically, by detecting the trouble of integrator and suppressing the rise of speed set voltage.  
     CONSTITUTION: When the integrator 2 develops a trouble during the acceleration of the elevator, the output  of the integrator goes as shown by Vs' and exceeds the sum of the speed set voltage Vix and a trouble detector set voltage VB. Therefore, a trouble detector operates a trouble detection relay 3-6, which is then self-held by a contact 3-7a. Simultaneously, a trouble detection auxiliary relay 20 is released and a switch 4 is shifted to the side for the speed set signal Vi. Then, a contact 20-5 is opened and the cathodes of thyristors T1, T2, T3 of a speed notch throw circuit 30 are disconnected from a power source N. Therefore, the signal Vi maintains a level corresponding to the time of trouble detection and does not drastically rise.

Title: Surface acoustic wave convolver
Inventor: EGARA KOUICHI
IPC: H03H9/72
Filed: 1990-05-21
Abstract: PURPOSE:To improve the convolution efficiency by operating the convolver at a temperature lower than a critical temperature of a superconducting material. CONSTITUTION:When an electric signal whose center angular frequency is omegais inputted to one stimulating comb-line electrode 2, a surface acoustic wave is stimulated from the stimulating comb-line electrode 2 and made incident guide paths 4-1-4-n. Similarly, when an electric signal whose center angular frequency is omega is inputted to other stimulating comb-line electrode 3, a surface acoustic wave is stimulated from the stimulating comb-line electrode 3 and made incident in guide paths 4-1-4-n. A surface acoustic wave whose center angular frequency is 2omega propagated in the + or -y axis direction is generated to both sides by the parametrix mixing phenomenon on the guide paths 4-1-4-n from the former surface acoustic waves. Since the comb-line electrode 5 is made of a superconducting material, the comb-line electrode 5 is in superconducting state at a temperature below the critical temperature Tc and the electric resistance of the electrode 5 is zero. Thus, the loss in the convolution output by the electrode finger resistance of the electrode 5 is not caused.

Title: Developing method of electrophotography
Inventor: MATSUMOTO FUYUHIKO
IPC: G03G13/08
Filed: 1978-10-23
Abstract: PURPOSE:To obtain good two color images by using conductive carrier for the carrier of the first chromatic color developer and making the potentials after the development of the regions of the photoreceptor corresponding to the first chromatic color less than the development start voltage. CONSTITUTION:Arrangement is so made that the residual potentials of the region a' corresponding to the first chromatic color, e.g., black, become less than the development start voltage V' after the first development. Because of this, conductive carrier is used for the carrier of the first chromatic color developer, i.e., black color developer, by which the latent image potential leakage from the carrier is increased at the first developing to reduce the residual potentials. As a result, at the time of  the second development, the red toner of the second chromatic color deposits only on the region b' corresponding to red and does not depost in the region a' corresponding to black at the second developing. In this way, the good two color images may be obtained.
