Title: Electrooptical electric field measuring apparatus
Inventor: OKUMICHI TAKEHIRO
IPC: G01R29/12
Filed: 1993-12-24
Abstract: PURPOSE:To allow higher sensitivity, higher spatial resolutions and a smaller size by making light passing through an electrooptical element concentrate so as to pass repeatedly near one point in the element by a plurality of reflection means. CONSTITUTION:Incident light 8 from a light source is admitted into an electrooptical element 1. The optical path length of light in the element 1 is increased and concentrated in a path of the transmission light so as to pass near one point in the element 1 repeatedly. The refractive index and the angle of incidence of the element 1 and a dielectric body are set properly and the film thickness is set to uniformize the phase of the reflected light so that the interference in the reflected wave is operated to allow the reflection of the most of the incident light. Thus, the light passing through the element 1 is concentrated so as to pass near one point in the element 1 by a plurality of reflection means thereby allowing a higher sensitivity and smaller size with the increase in the optical path of the light passing through the element 1 and the effect by an electric field near one point is increased with the concentration of the transmission light thereby enabling the obtaining of higher spatial resolutions.

Title: Control of data transfer
Inventor: YOKOTA HIDETOSHI
IPC: H04L47/32
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of a transfer speed by adding information indicating a random error detected in a received packet to a resending request and transferring the information added request to a transmitting station, transfer ring a resending request to the transmitting station in detecting a packet loss, starting flow control when a cause of a resending request is a packet loss, and continuing packet exchange when the cause is a random error. SOLUTION: In receiving a packet to a transmitting station itself, the transmitting station refers to the header of the packet, and when the identification(ID) code of a packet canceled by a receiving station due to a random error is registered, judges that the packet is lost due to noise or interference independent of congestion and resends the packet requested to be resent without starting flow control for evading congestion. When the ID code is not registered in the header of the packet, the transmitting station judges that the packet is lost due to a nonrandom error mainly caused by congestion such as a packet loss and starts flow control.

Filed: 1987-12-24
Abstract: PURPOSE:To use a low-accuracy image pickup lens by picking up reflected slit light from an object of measurement, finding the center position of picture elements corresponding to the reflected light, and calculating a distance according to the center position. CONSTITUTION:A slit light source 4 projects slit light on the object 7 of measurement and its reflected light is picked up by an image pickup means 5, whose output is inputted to an image processing means 6. The image processing means 6 inputs the picked-up image as an image represented by picture elements of optional gradations. Then a reflected light image range selection part selects the range of picture elements 5h representing a picture 5g of the reflected light. Then a center position arithmetic part calculates the center of gravity of the image within the range of the picture element 5h to find the center position G of the image 5g of the reflected light. Then, the distance to said object 7 of measurement is calculated by trigonometry from the center position of the image of the reflected light. Consequently, an image whose focal length is matched with an image pickup surface need not be projected, so the image pickup lens with low accuracy is constituted.
