Title: Method for controlling road information transmission system
Inventor: NISHIMOTO KEIICHI
IPC: H04W4/02
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To make the occurrence of a radio communication blind zone suppressible by presenting road information to each automobile so as to perform lane control for every vehicle height without causing any shadow area. SOLUTION: When an automobile 401 high in vehicle height enters between an automobile 402 low in vehicle height and a base station 105 in a road having plural traffic lanes, an on-vehicle station 402 becomes insensitive to radio communication and is not able to get road information because a shadow area 500 is caused behind the automobile 401. To eliminate such a situation, when the occurrence of the area 500 is detected based on information from a sensor 101, information that instructs lane change is produced and is transmitted to an on-vehicle station 401 to eliminate the area 500.  A communication processing part 103 of a road information transmission system which is installed in the range where plural traffic lanes exist and lane control in every height is performed produces lane control information based on the information of road situations obtained from the sensor 101, adds it to transmission data (road information) to each automobile and transmits it.

Filed: 1981-09-16
Abstract: PURPOSE:To elongate life of electrodes, to simplify a triggering structure, and to prevent the contamination of laser gas due to abraded material of the electrode, by arranging a dielectric electrode covered by a dielectric between a cathode and anode, and by steadily generating an AC discharge as an auxiliary discharge, e.g. silent discharge, between the cathode and anode or between either electrode and the auxiliary electrode. CONSTITUTION:The AC discharge is generated between the cathode 17 and the feeding line 19 and between the anode 1 and the feeding line 19 by the application of a voltage from an AC high voltage power source 21. Said AC discharge has inherent homogenity owing to the presence of the dielectric electrode 18. A low ionized state is steadily yielded in the vicinity of the cathode 17 and over the entire main discharge space. When a main discharge trigger switch 9 is made to be conducting state under the presence of the auxiliary discharge, the charge stored in a main discharge capacity 10 quickly flows between the cathode 17 and the anode 1, and the uniform pulse discharge is obtained over the entire electrode region.

IPC: G21F7/015
Filed: 1995-06-13
Abstract: PURPOSE: To improve operability by providing an operation room to a box body for handling a sample and preparing a pressure difference holding means to the operation room and box body. CONSTITUTION: A ventilator 21 is operated while a manual regulating valve 23 is adjusted manually and the internal pressures of an operation room and a box body 10 are set at a minute pressure difference.

Title: Camera equipped with subject information storage means
Inventor: HATA YOSHIAKI
IPC: G02B7/28
Filed: 1984-07-14
Abstract: PURPOSE:To perform proper focusing and exposure even when a main subject shifts in position in the viewfinder of a camera after light metering operation by storing distance information and brightness information on the subject in the storage means while an operation member is half-pressed. CONSTITUTION:The stored brightness and distance information regards the subject which is almost common within overlapping ranges of light metering M and range measurement DF as shown in a figure. Consequently, information necessary for photography with proper exposure in the focusing state of the subject to be shotted is stored by single-time operation. A visual field frame is shown by MF. Even if a change in composition of photography is made in this state, for example, so that the subject is positioned outside the frame of light metering and range measurement, the subject is photographed in an in-focus state with proper exposure. A strobe emits light automatically when the subject brightness is low, so even if the subject is not within the light metering and range finding range, strobe photography is performed automatically when the subject is dark.
