Title: Focal point detecting device
Inventor: OTAKA KEIJI
IPC: G02B7/34
Filed: 1988-06-10
Abstract: PURPOSE:To realize a focal point detecting device capable of high precision focal point detection which prevents unnecessary light incidence on a photodetector plane and causing ghost light by arranging two light limiting members which limit luminous flux within a certain optical path. CONSTITUTION:Plural light quantity distributions related to an object image are formed by using luminous flux which passed through the regions of different pupils on an objective lens 1, the relative positional relationship of the light quantity distributions are obtained by a light receiving means 5, and the focusing condition of the objective lens 1 is detected. Since a visual field mask 2 and a light shielding mask 24 are positioned respectively just before the field lens 3 and the light receiving means in the optical path from the objective lens 1 to the light receiving means 5, the unnecessary luminous flux incident on the peripheral area on the planes of the photodetector strings 5-1 and 5-2 is interrupted among the relatively widely set luminous flux from the visual field mask 2. Therefore, the minimum necessary luminous flux is incident on the photodetector strings, the ghost light caused by the multiplex reflection from the surface of a resin member 18, etc., is decreased, and the high precision focal point detection is realized.

Title: Fuel filter device
Inventor: IZUMITANI KOUJI
IPC: F02M37/22
Filed: 1983-08-04
Abstract: PURPOSE:To prevent a filter device from being badly operated due to corrosion by operating a heater control means by detecting, with a lead switch, the operation of a flexible member for detecting difference pressure across a filter assembly between its upstream and downstream portions in a filter device provided with a heater for heating a fuel. CONSTITUTION:When a fuel supplied from a fuel pump is fed from an inlet pipe 6 into a filter device body, the fuel pushes up a valve body 10 to open it, passes through a diaphragm chamber 12, and thereafter enters a filter assembly 2. Then, the fuel reaches a space part 5 for water storage, and water contained in said fuel is separated during its stay there. Successively, it is allowed to pass through a filter element 2b, filtrated, and cleaned, and therafter discharged from a fuel discharge port 1. At this time, when the fuel is at low temperature and any clogging is produced in the element 2b due to wax in the fuel, relatively large difference pressure is produced between flow passages 46, 47 on the upstream and downstream sides of the element 2b, allowing a diaphragm 48 to be moved to the left. Thus, a lead switch 40a is turned on by a magnet 42, allowing a current to be conducted to a heating device 21.

Abstract: PROBLEM TO BE SOLVED: To exactly output a display that reception is disabled with respect to a radio receiver of an SS-FH system. SOLUTION: By the radio receiver 11 of the SS-FH system, a receiving condition whether the reception is possible or not is judged based on data to be detected which is transmitted by each frequency channel of frequency hopping. Specifically, frequency of reception of the data to be detected by a radio unit 13 is counted by a counter 18, the counted frequency is compared with a threshold value held in a memory 17 by a comparison part 19 and when the counted frequency is not more than the threshold value, a message 'out of a range' indicating that the reception is disabled is displayed and outputted on a display by a display part 16.

Filed: 1980-10-14
Abstract: PURPOSE: The reaction mixture between chlorobenzene and chlorosulfonic acid is added to water or diluted sulfuric acid under specific conditions to decompose the excessive chlorosulfonic acid and remove hydrogen chloride out of the reaction system, thus producing the titled compound in liquid form economically without formation of waste water.  
     CONSTITUTION: The reaction mixture between chlorobenzene and chlorosulfonic acid is added to water or diluted sulfuric acid to decompose the excessive chlorosulfonic acid and the hydrogen chloride evolving is removed out of the reaction system. After the completion of the decomposition, the concentration of sulfuric acid is adjusted to 60W90% in the sulfuric acid layer and the objective compound is separated from the sulfuric acid layer at a temperature higher than 50°C. The temperature on the decomposition of chlorosulfonic acid is ain the range from room temperature 85°C, preferably from 40 to 75°C. Since the decomposition can be done at  elevated temperature, the cooling operation from outside is simple and the time is shortened. The sulfuric acid and hydrogen chloride formed as by-products are recovered in high concentration and reused.
