IPC: G01R31/04
Filed: 1989-02-17
Abstract: PURPOSE:To discriminate the quality of a contact by applying a square wave- like measuring signal and monitoring a response characteristic waveform at the time of inspecting whether a first and a second electric conductors are brought into contact or not. CONSTITUTION:In parallel lines connected to electrode pads 80, 82, a floating capacity C exists as a high frequency. When a square wave-like voltage (a) is applied to one of these parallel lines, a current (b) can be monitored by a size of the floating capacity C in the other electrode.

Abstract: PURPOSE:To shorten a cycle to prevent flicker of a picture and to increase the number of gradations by sending a display data signal to a signal electrode within one select time of a scanning electrode while repeatedly changing it at intervals of plural frames. CONSTITUTION:One display data signal is sent to the signal electrode within one select time of the scanning electrode and this signal is repeatedly changed at intervals of plural frames, and in this case, flicker of the picture is scarecely conspicuous when the cycle of repeat is three or less frames preferably. Consequently, the display data signal is changed at intervals of three or less frames in five kinds of signal sending mode, namely, the mode not to change the signal at all, the mode to change it once per three frames, the mode to change it once per two frames, the mode to change it twice per three frames, and the mode to change to throughout. These modes are combined to increase the number of gradations without extending the cycle of repeat of the display data signal, namely, increasing the number of frames (flicker of the picture).

Filed: 1989-02-20
Abstract: PURPOSE: To limit the stroke of a hollow roller easily and reliably by providing a crosshead with a conduit that leads from a cylinder chamber to the outside of the crosshead, and by closing the conduit inlet normally and opening it at a limit stroke with the use of a supporting plunger. CONSTITUTION: A crosshead 1 is formed in its outer surface with a cylinder chamber 9, which communicates with a passage 8 for hydraulic operating fluid and in which a lower portion 11 of a piston-like supporting plunger 20 having a sealing ring packing 12 is displaced.

Title: Fuel injection device
Inventor: UEHARA TETSUYA
IPC: F02M61/16
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To perform suppression of the generation of NOX and combustion noise by a method wherein an auxiliary fuel chamber is formed at a slide part between a nozzle body and a needle valve and a communication passage to intercommunicate the fuel chamber and the auxiliary fuel chamber is provided. SOLUTION: Since, when the lift of a needle valve 2 at the initial stage of injection is low, a fuel chamber 5 and an auxiliary fuel chamber 3 are intercommunicated, the substantial volume of the fuel chamber is increased. Thus, since an increase in the pressure of the fuel chamber 5 is suppressed, an initial injection rate is suppressed. Thereafter, when the needle valve 2 is further lifted and a communication passage 4 is closed, the fuel chamber 5 and the auxiliary fuel chamber 3 are disconnected from each other and the substantial volume of the fuel chamber is reduced. Thereby, a pressure in the combustion chamber is rapidly increased and a high injection rate is obtained.  This constitution reduces the injection rate to a low value at the initial stage of injection and increases the injection rate to a high value at the later stage, and performs suppression of the generation of NOX and combustion noise.

Abstract: PROBLEM TO BE SOLVED: To decrease the number of times of use of a directional coupler, and to reduce any multiplexing loss or demultiplexing loss by executing wavelength arrangement of a signal light not equally but with intervals by dividing it into blocks for each several wavelength for wavelength synthesis and wavelength separation. SOLUTION: The wavelength arrangement of a signal light is executed not equally but with intervals by dividing it into blocks(from the first block to the (n)th block) for each several wavelength. An optical multiplexing circuit is an optical circuit or an optical part for generating and outputting a wavelength multiplexed signal light from inputted plural single wavelength signal lights. Then, the inputted plural single wavelength signal lights are synthesized by the optical multiplexing circuit, and the plural wavelength multiplexed signal lights from the first block to the (n)th block can be obtained.  Moreover, the wavelength multiplexed signal light from the first block to the (n)th block are wavelength-synthesized by a wavelength multiplexing coupler by using the clearances of the wavelength arrangement between the blocks so that the target wavelength multiplexed signal lights can be obtained.
