Title: Controller for generation of waveform
Inventor: MURAKAMI JIYOUJI
IPC: G06F1/02
Filed: 1984-02-29
Abstract: PURPOSE:To produce a complicated waveform at a high speed and with general- purpose properties and without deteriorating the CPU processing capacity, by using a memory device RAM which is capable of reading/writing and a memory control circuit in addition to a CPU and a waveform generator. CONSTITUTION:Both an RAM3 and an RAM control circuit 4 are not controlled by a CPU1 excepting for a rewriting mode for replacement after the information is once written to the RAM3. The circuit 4 reads the control information out of the RAM3 via a bus 6 and decodes the control information to decide a read address for readout of the waveform information from the RAM3. This decided read address is applied to the RAM3 via a bus 7. Thus the waveform information is read out and supplied to the circuit 4 and a waveform generating circuit 2. The circuit 4 decides the next read address from the received waveform information and the stored control information. In such a way, the reading action is continued. The circuit 2 transmits a signal of a high or low level, i.e., a pulse train in accordance with the received waveform information.

IPC: G01R29/08
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To estimate a three-dimensional wave source distribution accurately even when a wave source is close to a hologram observation plane. SOLUTION: Hologram observation is performed by two frequency method (Step 101) and a hologram image is reproduced (Step 102).

Title: Optical transmission device
Inventor: TANEI HEIKICHI
IPC: G02F1/13
Filed: 1985-02-27
Abstract: PURPOSE:To decrease optical-axis adjustment positions and to reduce the size of an optical transmissiohn device by using four reflecting films and one liquid-crystal cell and forming an optical switch according to whether there is a voltage impressed to the liquid-crystal cell or not. CONSTITUTION:When no voltage is impressed between transparent electrodes 13 and 13, major axes of liquid crystal molecules are oriented in parallel to the transparent electrodes and at right angles to the paper surface, so polarized light E'' emitted from a receiving optical fiber 4 is polarized light which oscillates at right angles to the long-axis direction of the liquid-crystal molecules and ordinary light. Consequently, the light is reflected by a reflecting mirror surface 14 to be made incident on the interface between glass and a transparent electrode and refracted downward; and the light is reflected totally by the interference between the transparent electrode and a liquid-crystal film and further reflected by a reflecting mirror surface 15 to reach a transmitting optical fiber 4'. When a proper voltage is impressed between the transparent electrodes, on the other hand, the major axes of the liquid-crystal molecules are oriented at right angles to the transparent electrodes, so polarized light E'' emitted from the receiving optical fiber 4 is extraordinary light, which is transmitted through the liquid-crystal film and reflected by a reflecting mirror surface 17 to reach a photodetecting element 20.
