Publication number: 20070163199Abstract: The invention is a log-made member for a large-scale truss structure. A truss structural member 1 comprises a log 2 cut so as to form flat surfaces on butt ends 2A thereof. A connector 4 slidably holds a shank 6m of a fastening bolt 6 and holds the periphery of the butt ends. Large lag screws 5 fix the connector 4 to the butt end 2A of the log. The connector 4 is disposed between the joint device 3 and the log 2, and is composed of a first element 4A and a second element 4B which engage with the portion of a counter-node side of the first element 4A. The first element 4A is provided with an axial symmetrical shell accommodating an elastic element 10 for biasing the fastening bolt 6. The second element is 4B is fixed to the log 2 by plural lag screws 5 so as to hold the butt end by using an annular thorn 4c so that the portion of the counter-node side thereof contacts the butt end 2A without any clearance.Type: ApplicationFiled: September 21, 2004Publication date: July 19, 2007Inventors: Katsuhiko Imai, Atsuo Takino, Noriyuki Fujita, Kozo Wakiyama, Shizuo Tsuzioka, Masumi Fujimoto, Masanori Inada, Hiroko Fukutome

Patent number: 5237868Abstract: A thermal flow sensor comprising a bridge circuit positioned in a fluid and including a platinum wire as a thermal resistor, an air temperature sensor and a pair of resistors, and a temperature control circuit for controlling a current flowing through the platinum wire to keep the bridge circuit in a thermally balanced condition. A voltage V.sub.h depending on a flow rate and output from the bridge circuit is input to a non-inverting input terminal of an operational amplifier. A sum of the currents output from the first and second constant current circuits connected to the non-inverting and inverting input terminals of the operational amplifier is set to zero by a constant current control circuit when the output voltage V.sub.h is equal to or less than a predetermined value and gradually increases from zero with an increase in the output voltage V.sub.h when V.sub.h is higher than the predetermined value.Type: GrantFiled: December 30, 1991Date of Patent: August 24, 1993Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Masanori Inada

Patent number: 5214958Abstract: An apparatus for defecting occurrence of misfiring in an internal combustion engine with improved reliability. A change in an angular velocity of a crankshaft of the engine and a change in the output of an air/fuel ratio sensor are monitored. Only when both changes indicate occurrence of misfiring independently from each other, it is decided that misfiring in the cylinder has taken place. Reliability in misfiring detection is improved by using the results obtained through at least two mutually different types of misfiring detections.Type: GrantFiled: February 13, 1992Date of Patent: June 1, 1993Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Masanori Inada, Akira Demizu, Akihiro Nakagawa

Patent number: 5147775Abstract: A bipolar transistor with improved high-frequency performance is invented. The improvement is attained by eliminating a parasitic base-collector capacitance. The invented transistor is constructed upon a semi-insulating substrate, and wherein a region which underlies an extrinsic base region is semi-insulative such that the extrinsic base region does not substantially overlap the collector contact region and the collector region when viewed in the direction perpendicular to the substrate. Here, it's worthwhile to point out that a portion under the extrinsic base region is made completely semi-insulative down to the substrate. As a result, the transistor has substantially no parasitic base-collector capacitance.Type: GrantFiled: August 21, 1990Date of Patent: September 15, 1992Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yorito Ota, Masanori Inada, Manabu Yanagihara

Patent number: 5037769Abstract: A semiconductor device of a multilayer structure comprising semiconductor materials of different properties manufactured by using at least a step of epitaxially forming a semiconductor material layer on a substrate and a passivation film layer thereover, a step of introducing impurities into specific portions of the epitaxially formed semiconductor material layer and a step of removing the passivation film layer formed directly above the epitaxially formed semiconductor material layer within an epitaxial device and then applying epitaxial growing. Impurities introduced additionally to specific portions of the layer inside are substantially eliminated at the boundary adjacent the layer above the region introduced with impurities and the properties of the thus-produced semiconductors vary abruptly at the boundary between the layer in which the impurities are introduced and the layer thereabove.Type: GrantFiled: March 28, 1989Date of Patent: August 6, 1991Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masanori Inada, Kazuo Eda, Yorito Ota

Patent number: 5024083Abstract: A thermal flow sensor has a heat-sensitive resistor which is disposed at a predetermined angle relative to the line of stream of a fluid, and which has its heat-sensitive portion disposed on the surface portion of a substrate which is positioned downstream in the direction in which the fluid flows. Since the heat-sensitive resistor is already disposed at a predetermined angle relative to the line of stream of the fluid, this permits only slight influence on, hence, variation in detection characteristic to be caused by deviation in the disposition angle. Since the heat-sensitive portion is disposed on a surface portion positioned downstream in the direction of fluid flow, this restrains dust contained in air from directly depositing on the heat-sensitive portion, hence, from causing variation in detection characteristic.Type: GrantFiled: December 15, 1989Date of Patent: June 18, 1991Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Masanori Inada, Hichiro Ohtani

Using the thus formed emitter (the collector, in the inverted type) electrode metal layer, a base electrode metal layer is formed, by self-alignment, adjacent to the emitter (the collector, in the inverted type).Type: GrantFiled: October 11, 1989Date of Patent: October 23, 1990Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masanori Inada, Kazuo Eda, Yorito Ota, Atsushi Nakagawa, Manabu Yanagihara
