Title: Hydraulic circuit structure of work vehicle
Inventor: KAGAWA TOSHIAKI
IPC: A01B63/00
Filed: 1986-11-04
Abstract: PURPOSE:To prevent shock at the time of stopping an operating device by installing a choke oil passage for connecting a valve opening energizeing oil chamber to a valve closing energizing oil chamber on a valve body. CONSTITUTION:A choke oil passage 8a for connecting a valve opening energizing oil chamber to a valve closing endrgizing oil chamber 10 is installed on a valve body 8. Thus, even if the oil pressure in the valve closing energizing oil chamber 10 of a closing valve B is quickly reduced by throttling action when a main spool 17 is operated from a pressurized oil supply position to a neutral stop-position, the closing valve B is not opened abruptly as the pressurized oil in the valve opening energizing oil chamber 9 flows into the valve closing energizing oil chamber 10 through the choke oil passage 8a, with the result that abrupt reduction of the pressure in an oil passage connected to a hydraulic cylinder 4 can be avoided. Consequently, shock at the time of stopping the operating device can be prevented since the operating device stops with a little deceleration before stopping.

IPC: H01P7/10
Filed: 1990-10-01
Abstract: PURPOSE:To obtain a dielectric ceramic composition having high dielectric constant, low dielectric loss in a microwave region, and small temperature coefficient of the dielectric constant by specifying the composition of the dielectric ceramic composition comprised of lead oxide, calcium oxide. zirconium oxide, magnesium oxide, and niobium oxide. CONSTITUTION:In a dielectric ceramic composition having a formula; (Pb1-xCax) Zr1-y(Ni1/3Nb2/3)yO3, the composition is within an area defined by points (x, y); A (0.35, 1.0), B (0.6, 1.0), c (0.6, 0.25), D (0.5, 0.0), E (0.25, 0.0), and F (0.45, 0.5) in an xy coordinate system. The composition on the lines y=0 and y=1.0 is excluded. Consequently, a part of Zr of calcium lead zirconate, (PbCa)ZrO3, is substituted with magnesium niobate, (Mg1/3Nb2/3)O3. As a result, high dielectric constant, high Q value in a microwave region, and good temperature coefficient of the dielectric constant are obtained.

Filed: 1991-10-14
Abstract: PURPOSE:To shorten the overall length and to relax the tolerance of the manufacture by arranging a groove between two optical waveguides for phase modulation and loosely coupling the two optical waveguides for two phase modulation. CONSTITUTION:The two optical waveguides which constitute 3dB coupler parts 200 and 400 and two phase modulation parts 300A and 300B which constitute Mach-Zehnder parts are constituted while connected by linear optical waveguides. The two optical waveguides of those phase modulation parts 300A and 300B should suppress optical coupling between the optical waveguides so as to constitute the Mach-Zehnder parts. For the purpose, the two optical waveguides for phase modulation need loosely be coupled and the cut groove 10 is formed by etching in layers 4 and 5 extending to the part of a core 5. Thus, the groove is arranged between the two optical waveguides for phase modulation, which are loosely coupled to make the gap between the two phase modulating optical waveguides small, thereby shortening the overall length of the optical switch.

They are covered with a silicon oxide film 13, and a photoresist film 14 is formed by application. When emitted light 16 for exposure is emitted to a substance to be exposed and irradiated like this through an optical pattern 15, reflected rays 17 and 17a are generated. From the slant surfaces 12' reflected rays 17 in a direction oblique to the direction of incidence are generated, and regions wider than the optical pattern 15 of the photoresist film 14 are exposed to light. Consequently, rectangular contact holes can be formed in the case of positive resist since a square mask projection pattern 10' acts like a long and narrow rectangular pattern 10a, and the photoresist film 14 is exposed to light.

Filed: 1984-12-19
Abstract: PURPOSE:To decrease crosstalk by controlling an active element to decrease the leakage when a switch circuit using the active element switching a signal is turned off. CONSTITUTION:In outputting a signal inputted from an input terminal 501 to an output terminal 3, an input switch control signal is inputted to a control terminal 101 to turn on switch circuits 503, 4 and to turn off other switch circuits 504, 5 and a potential control circuit 9 is controlled at the same time to turn on an internal switch 901 to give an output to a potential application terminal of an internal constant voltage source 902. Thus, a signal superimposing an AC signal 506 on the constant voltage source 508 appears an input terminal 502 and a signal superimposing an AC signal 505 on the constant voltage source 505 appears at an output terminal 3 via the switch circuits 503, 4. When the constant voltage sources 507, 508 are equal and the AC signals 505, 506 are sufficiently small, floating static capacitances 514, 7 are decreased by giving a reverse bias to a transistor of the switch circuits 504, 5 with a potential difference between the potential 902 of the potential control circuit 9 and the constant voltage sources 507, 508. Thus, the leakage of the input signal 506 to the output terminal 3 is decreased in this way.

Title: Processing system for initial setting in automatic operation mode
Inventor: SHIMIZU YOSHIKATSU
IPC: G06F1/24
Filed: 1986-11-07
Abstract: PURPOSE:To perform the correct initial setting processing in an automatic operation mode by carrying out only the initial setting processing of a system when coincidence is secured between end dates of automatic initial program loading jobs in the preceding time and this time and then carrying out the initial setting processing after an initializing process when no coincidence is obtained between said both end dates. CONSTITUTION:When coincidence is secured between the end date of the preceding automatic initial program loading IPL job and the end date of the IPL job of this time, only the initial setting processing of a system is carried out. While the initial setting processing is carried out after an initializing process if no coincidence is secured between said end dates. Thus it is possible to correctly carry out the initial setting processing in an automatic operation mode in accordance with the system mode. Then the system resources can be held in a system breakdown mode.
