Title: Photodiode and laser device using this photo diode
Inventor: TAKAHASHI MASAO
IPC: H01S3/23
Filed: 1990-10-23
Abstract: PURPOSE:To allow a forward beam to pass and interrupt a return beam by allowing the forward beam incident on a first imaging element to pass through a spatial filter, a scattering body and a second imaging element, and scattering the reverse beam incident on the second imaging element, with a scattering body, and then interrupting it with a space filter. CONSTITUTION:When a light enters a first lens 12 from left side, the incident light is focused at the focus F1, and further passes through a pinhole 14 near the focus and reaches a scattering plate 16. This light is scattered by a scattering plate 16, and reaches a second lens 18, and is turned to a parallel light with this lens 18. In contrast to this, the lights, which have entered the second lens 18 from the reverse direction, condense in the scattering plate 16 leading to the focus position F2, and scatter. Most of these scattered lights can not pass the pin hole 14 positioned in the direction of the propagation and are cut. Besides, just a part of the scattered lights pass the pin hole 14, but since the position of the focus F1 of the first lens 12 and the position of the scattering plate 16 are shifted from each other, the light, which has passed the first lens 12, does not become a parallel light, and can not travel in the regular light path.

Abstract: PURPOSE:To extract data with a high stability by interposing the second computer system between a direction detecting system and a central center system. CONSTITUTION:Between a direction detecting system 4 and a central center system 7, a sub-center system 18 is interposed. By the system 18, each average value is calculated with regard to each direction, each intensity, and each frequency against a radio wave data group which has been collected by the system 4, and a distribution range in which each data is contained by, for instance, >=90%, namely, a common area of each direction area is led out. This common area shows an estimated area for transmitting a radio wave, and this estimated area is displayed by a prescribed color, on a master graphic computer 5, or a sub-graphic computer 16. In this way, since data which have been collected by the system 4 are combined and put in order by the system 18, data can be extracted with a high stability.

Title: Circuit and method for receiving and transmitting control and status information
Inventor: TOOMASU ERU WAANIMONTO
IPC: G06F11/10
Filed: 1992-09-29
Abstract: PURPOSE: To attain control of a transmitter-receiver and communication of status information effectively between a signal processor and an audio source or a sink. CONSTITUTION: During transmission of digital audio data from an audio source and a signal processor, a comparator 49 compares a CRCC byte of a channel status information block with a theoretical generated by a CRCC generator 48. The comparator, comparing the actual and theoretial CRCC bytes, provides an output of a single bit that denotes whether or not the audio data have been transmitted correctly. The remaining bits of the CRCC byte are used to transfer status information corresponding to a transmitter 16. During the transmission of digital data from the signal processor to the audio sink 24, the parity bit of a sub-frame of the digital data is used to transfer a program information from the signal processor to the audio sink.
