Patent number: 11916521Abstract: A radio-frequency module includes a mounting substrate and first and second power amplifiers. The first and second power amplifiers are each mounted on one main surface of the mounting substrate. The first power amplifier includes a first input terminal and a first outer periphery. The first outer periphery includes a first edge section. The second power amplifier includes a second input terminal and a second outer periphery. The second outer periphery includes a second edge section. The second edge section opposes the first edge section in a first direction. The first input terminal is disposed in the first edge section of the first power amplifier. The second input terminal is disposed in the second edge section of the second power amplifier. The first and second input terminals do not overlap each other in the first direction.Type: GrantFiled: June 8, 2021Date of Patent: February 27, 2024Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Yoshito Matsumura, Morio Takeuchi, Yukiya Yamaguchi, Shigeru Tsuchida, Hidetaka Takahashi

Patent number: 6681975Abstract: A driver unit of a vertically slidable type is constructed by mounting a staple cartridge to a cartridge holder so as to freely slide in a vertical direction, and by urging the staple cartridge toward a clincher unit opposed thereto by a spring. When a clincher sleeve has descended to push the staple cartridge, the staple cartridge will move up and down in parallel, and accordingly, a relative angle of a clincher to a driver plate will not change.Type: GrantFiled: August 2, 2001Date of Patent: January 27, 2004Assignee: Max Co., Ltd.Inventor: Morio Yamaguchi

Patent number: 6592115Abstract: A sheet postprocessing apparatus includes a magazine unit and a clincher unit. The magazine unit has a driver which is vertically movable relative to a magazine for storing staple sheets. The clincher unit has a clincher holder, a driving mechanism for vertically moving the clincher holder, and a driving source of the driving mechanism. The magazine unit and the clincher unit are disposed vertically opposite to each other. In the sheet postprocessing apparatus, a material to be stapled is inserted between the magazine unit and the clincher unit. The clincher holder of the clincher unit is moved closer to the magazine unit by using the driving source so that a staple may be passed through the material and bent.Type: GrantFiled: February 27, 2001Date of Patent: July 15, 2003Assignee: Max Co., Ltd.Inventor: Morio Yamaguchi

Patent number: 5239904Abstract: A punch is disclosed, which can be used with an automatic paper feeder or a plane paper copier for receiving sheet-like members one by one from such machine and forming punched holes in each sheet-like member at a punching position thereof. A punching member is disposed in correspondence to the punching position for effecting punching with a predetermined stroke. A dimensional strain generated in an electrical-to-mechanical conversion element such as a piezoelectric element or a magnetostriction element is transmitted after enlargement by an enlarging member disposed to surround the element through a movable output terminal and an operation transmission lever to the punching member to cause high speed operation thereof in a predetermined stroke range. High quality punched holes free from curved edges or the like difficiency thus can be formed even in a continuous feed state without holding the sheet-like members stationary for a while.Type: GrantFiled: August 2, 1991Date of Patent: August 31, 1993Assignee: Max Co., Ltd.Inventors: Morio Yamaguchi, Takashi Uchida

Patent number: 4976553Abstract: A very small displacement enlargement mechanism is disclosed, in which a first stationary frame and a second movable frame are disposed on the opposite sides of a piezoelectric element for producing a strain in a longitudinal direction according to an applied voltage. A movable member consisting of a plurality of elements linked together into a substantially parallelogrammic form is disposed between the two frames such as to surround the piezoelectric element. An element of the movable member or the side of the first frame is united integrally to the first frame, and another element which is on the side of the second frame and faces the first-mentioned element is united integrally to the second frame. The strain of the piezoelectric element produces a relative displacement of the two frames via the movable member, and the relative displacement is transmitted as an enlarged output to a drive wire.Type: GrantFiled: December 8, 1988Date of Patent: December 11, 1990Assignee: Max Co., Ltd.Inventors: Morio Yamaguchi, Yasunori Kudoh, Takashi Nakazato

Patent number: 4884906Abstract: In a serial printer having a single type wheel, the type wheel is rotatably supported on a rocking frame, which is rockable relatively to a fixed frame, so as to be fixed with respect to the direction of the axis of rotation, and is rotated by means of a single drive motor. A drive transmission mechanism between the motor and the type wheel includes a main shaft rotatably supported by the rocking frame and a main cam rotatable in one with the main shaft. Each revolution of the main shaft and the main cam is divided into at least three rotational angular ranges, which are allotted individually for operation processes of type selection, printing, and sheet feed. All these processes are executed with use of the single drive motor as a drive source. A sheet holding mechanism continuously maintains a paper hold state until a specific character, such as an end mark, is printed after the start of a printing cycle. A printing sheet is held and released by means of the aforesaid drive motor as the drive source.Type: GrantFiled: February 26, 1988Date of Patent: December 5, 1989Assignee: Max, Co., Ltd.Inventor: Morio Yamaguchi

Patent number: 4711170Abstract: The present invention relates to a printing wire driving device in a wire dot printer which can perform accurate control with small power and has a large printing wire driving power. In the present invention, a driving member is driven by an eccentric cam. The printing wire can be positively driven with high accuracy by this driving member when a maintaining electromagnet or piezo-actuator holds the wire and driving member in alignment. Otherwise, a biasing member pushes the wire or driving member out of alignment.Type: GrantFiled: December 27, 1985Date of Patent: December 8, 1987Assignee: Max Co., Ltd.Inventor: Morio Yamaguchi

Patent number: 3943851Abstract: A screen setting apparatus accurately locks a screen in position so that reference marks of the screen come directly in line with reference marks of a printing table, which table secures a sheet material to be printed. The apparatus comprises three registration devices, a screen having reference marks thereon, a screen fixing device, and a printing table securing a sheet material to be printed and having reference marks. The three registration devices are a first registration device, the reference mark of the printing table corresponding to a fixed relationship of the second registration device (i.e., a reticle) and a third registration device. The reticle is lined up with the reference mark of the screen and then the screen is locked in opposition by connecting the screen fixing device with the first registration device.Type: GrantFiled: June 22, 1973Date of Patent: March 16, 1976Assignee: Pilot Man-Nen-Kitsu Kabushiki KaishaInventors: Kunio Inada, Morio Yamaguchi
