Title: Image forming device
Inventor: HAGA MITSUHIRO
IPC: G03G15/00
Filed: 1990-04-23
Abstract: PURPOSE:To detect the rotation of an image carrier with high precision by positioning an encoder shaft coaxially with respect to a rotary shaft by means of the joining of the joining parts of the rotary shaft and the encoder shaft when the image carrier is mounted on a main body. CONSTITUTION:When the driving action of the main body is started, a belt 13 is driven, and a pulley 9 is rotated. When the pulley 9 is rotated forward, a roller one-way clutch 8 is locked and the pulley 9 and a drum shaft 3 are integrally coupled. Thus, the pulley 9 is positioned by the shaft 3, and is independent of an encoder supporting frame 12. Therefore, the rotary vibration of the pulley 9 does not influence on an encoder 19 via the frame 12. Even if the coupling of the pulley 9 and shaft 3 is not completely integrated and a deviation slightly occurs, a taper shaft 15 is driven by the shaft 3, so that the encoder 19 can be rotated in synchronization with the rotation of the image carrier 1 without giving an influence to the precision of a driving part.

Inventor: HONDA SHIYOUICHI
IPC: F01L1/26
Filed: 1983-06-13
Abstract: PURPOSE:To simplify the valve system by a structure wherein two groups of two rocker arms, only one rocker arm of each group of which is directly driven by a cam and the two rocker arms of each of which are connected to and separated from each other by means of a plunger actuated in response to oil pressure, enable to open and close two suction valves and two exhaust valves, all of which are arranged on one and same cylinder, or only the two suction valves. CONSTITUTION:Two suction valves and two exhaust valves are arranged per cylinder and driven by means of first rocker arms 19 and 48 and second rocker arms 20 and 49 respectively. Only one of the first rocker arm and the second rocker arm, concretly the first rocker arm, is directly driven by a cam on each set of the first and second rocker arms. Sets of the first and second rocker arms or only the first rocker arms are rocked so as to open and close both the suction valves and the exhaust valves or only the suction valves by connecting and separating the second rocker arms to/from the first rocker arms by means of the shifting movement of plungers 32 provided in cylinder holes 33. Oil pressure is supplied under the control of a valve action change-over valve 55 through a feed oil passage 37 in a rocker arm supporting shaft 18, a passage 19 in a rocker arm and a communicating hole of both the passages to the cylinder hole 33 of each first rocker arm. Due to the structure as mentioned above, only the direct drive of the first rocker arms are enough, resulting in simplifying the constitution of a valve gear.

IPC: H03B19/00
Filed: 1986-05-08
Abstract: PURPOSE:To make the frequency dividing ratio variable by inserting a varactor diode into a closed loop feeding back the own mixer output via a delay circuit. CONSTITUTION:When a signal of a frequency f0 is inputted to an input terminal 1, a signal of a frequency mf0/(m+1) (m is an integer) being one of the frequency components of the input signal is outputted from a mixer 2, and fed back gain to the mixer 2 via a feedback loop comprising delay lines 3, 11, amplifiers 4, 13 and a varactor diode 8. The feedback signal and the input signal are mixed by the mixer 2 and a signal of a frequency f0 + or -mf0/(m+1) is outputted and in setting the natural frequency of said feedback loop near the frequency f0/(m+1), only the frequency component of f0-mf0/(m+1)=f0/(m+1) is extracted from a terminal 12. Since said natural frequency is made variable by the capacitance change in the varactor diode 8, the frequency division ratio is made variable by the varactor diode 8.

Title: Toner carrier
Inventor: YAMANAKA YASUO
IPC: G03G15/09
Filed: 1994-04-22
Abstract: PURPOSE:To obtain a toner carrier body which prevents sticking of a toner and can be brought into soft contact with a latent image carrier without causing scratches not only on a latent image carrier having flexibility but also on a rigid latent image carrier by forming a specified mixture on the surface of a conductive supporting body. CONSTITUTION:This toner carrier body 2 is used to carry and transfer a magnetic toner to visualize an electrostatic latent image while rotating. The carrier body 2 has a mixture layer of ethylene-ethylacrylate copolymer, silicon-ethylene- ethylacrylate copolymer, and ferromagnetic powder formed on the surface of a conductive supporting body 5. In this method, it is preferable to preliminarily subject particles of the ferromagnetic powder to amino-silane coupling treatment. Thereby, sticking of the magnetic toner to be carried is hardly caused. Since the surface hardness of the carrier body is low, problems such as scratches on a latent image holding body to be in contact are avoided and durability of the latent image holding body is further improved.

IPC: G01S7/521
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain the hydrophone with a cardioid directivity that employs a single cylinder of small size and light weight. SOLUTION: A cylindrical sensing section 8 uses cylindrical bases 4(4a, 4b), split axially as reinforcement members and is configured by mounting a polymer piezoelectric material 7 on their inner circumferential faces and outer circumferential faces. The two cylindrical sensing sections 8 are mounted on a torus base 6 at one-side opposed ends and supported at a shape and mass center. A sensor section 1 provided with the two cylindrical sensing sections 8 is surrounded by a cage-type case 9, and the case 9 is supported in a boot 12 with a foaming material 11. A sound wave at the outside of the boot 12 is delivered to the polymer piezoelectric material 7 by using the case 9 and a filling liquid 13 filled in the boot 12 as an acoustic medium, and mechanical distortion by a sound wave is converted into an omnidirectional output and a bidirectional output at a preamplifier 2.  A maximum sensitivity of the bidirectional outputs caused at an interval of 180 deg. and the sensitivity of the omnidirectional output are made equal to each other by main amplifiers 3a, 3b of a control section 3, and a phase shifter 3c of the control section 3 shifts a phase of the bidirectional outputs by π/2. The cardioid directivity is obtained by synthesizing the phase-shifted bidirectional outputs and the ominidirectional output.
