Title: Surface acoustic wave beam width converter
Inventor: NAKAMURA KENJI
IPC: H03H3/08
Filed: 1984-11-07
Abstract: PURPOSE:To minimize generation of ununiformity of power distribution of a surface acoustic wave by dividing a thin film surface acoustic wave conductive path into plural paths along the propagating direction of a surface acoustic wave. CONSTITUTION:The thin film acoustic wave conductive path consists of the plural thin film surface acoustic wave conductive paths 5a-5e and they are divided by small gaps 6a4n6d. When an incident surface acoustic wave having a beam width LA is incident in a beam width converter forming in this way, the surface acoustic wave is propagated while being divided uniformly to the paths 5a-5e and converted into a surface acoustic wave 2 having a beam width L4dB. Thus, the irradiated surface acoustic wave 2 has a nearly uniform power distribution having the beam width LB. Further, a beam width reducing converter is obtained by inverting the incident and irradiating direction of the surface acoustic wave. Thus, generation of ununiformity of the power distribution of the surface acoustic wave is minimized.

Title: Electrophotographic method
Inventor: TAKEUCHI AKIHIKO
IPC: G03G13/00
Filed: 1982-12-23
Abstract: PURPOSE:To prevent lowering of dark potential of a photosensitive body and to form a good image free from uneven density by charging said body to polarity reverse to that of an electrostatic image after an electrostatic image forming step. CONSTITUTION:A charged state of a photosensitive body immediately after charging is as shown in a figure I-A, and charge on the surface of an a-Si layer 1 is given by corona ions, it is difficult to enter the a-Si layer, and the charge remains on the surface. On the other hand, charge induced on the side of the substrate 2 is injected into the inside of the layer 1. A figure I-B shows a state of invasion of the charge when said body 4 comes to the position of a probe 10, and the invasion proceeds to some degree. A figure I-C shows the state of charge in which the charge injected from the side of the substrate 2 is again swept away to the substrate 2 by giving reverse polarity charge, and accumulation of space charge in the inside of the layer 1 is prevented as shown in a figure I-D. Since space charge is swept away at each charging, dark potential lowering is kept extremely low, and a good image free from uneven density can be obtained.

Title: Alternate memory control system
Inventor: IHI TAKASHI
IPC: G06F12/16
Filed: 1987-09-19
Abstract: PURPOSE:To reduce the occurring probability of 2-bit errors by validating a spare RAM after a bit corrected by an error correcting circuit into at least the spare RAM. CONSTITUTION:When a burst error detecting means decides a burst error, the RAM having a burst error is replaced with a spare RAM via an allocation means. Then a release job means inhibits the input of a bit read out of the spare RAM to an error correction ECC circuit. Thus the bit read out of the faulty RAM is inputted as it is to the ECC circuit and the corresponding bit corrected by the ECC circuit is written into the spare RAM. A spare RAM validating means sets the bit read out of the spare RAM under an enable state after the end of a release job. Then the spare RAM is validated. Thus it is possible to extremely reduce the probability where a 2-bit error occurs in a release job.
