Title: Coreless motor
Inventor: FUKUOKA KIMIMICHI
IPC: H02K3/04
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To employ reflow-soldering for electric and mechanical connection to an apparatus by using polyamide series thermal fusion resin as basic resin, and blending epoxy series thermosetting resin with it, for the self-fusion layer of a winding which forms a cylindrical coil. SOLUTION: This coreless motor, which involves a rotating shaft which is penetratingly-fixed on the central part of a cylindrical coil supporting body, and a rotor consisting of a commutator disposed on a cylindrical coil or the rotating shaft, is formed with a roughly-cylindrical frame surrounding the cylindrical coil through a clearance by disposing a cylindrical magnetic field magnet in the inside space of the cylinder coil and fixing the cylindrical magnetic field magnet together with a brush which is brought into contact with the commutator. This coreless motor is provided with a cylindrical part consisting of a winding involving a self-fusion layer 1 formed out of resin obtained by using polyamide series thermal fusion resin as basic resin and blending it with epoxy series thermosetting resin. It is thus possible to suppress deformation of the cylinder coil caused by high temperature at the time of flow-soldering of the motor.

Title: Composite dielectric and manufacture thereof
Inventor: TSUZAKI MICHIMASA
IPC: H01B3/00
Filed: 1990-01-20
Abstract: PURPOSE:To obtain sufficient dielectric constant with a composite dielectric in which inorganic dielectric powder is dispersed in plastic by distributing the dielectric over an entire area of the dielectric in a state where the inorganic dielectric powder is distributed locally at a high density. CONSTITUTION:In a composite dielectric in which inorganic dielectric powder 1 is dispersed in resin 2, the amount of the powder 1 connected in straight lines in the resin 2 is larger in the case the inorganic dielectric powder 1 is dispersed with locally high density than the in the case the powder 1 is uniformly dispersed. As a result, the dielectric constant is higher than conventional dielectrics containing the same amount of additive of the dielectric powder because of increased amount of the inorganic dielectric in the form of electrically parallel connections. This causes the inorganic dielectric powder 1 mixed in to be utilized more effectively to contribute to the increase in the dielectric constant.

Title: Demodulation circuit for frequency modulation signal
Inventor: MASUDA ISAO
IPC: H04N5/92
Filed: 1990-01-20
Abstract: PURPOSE:To eliminate the need for a means to adjust the amplitude after demodulation by switching a demodulation sensitivity in response to a frequency band occupied by a signal to make the amplitude of a demodulation output nearly constant independently of the deviation by a signal transmission system (frequency deviation). CONSTITUTION:One of inputted FM signals VI divided into two at a branch point alpha is sent as it is as the main signal to a multiplier 11, and the other is sent to the multiplier 11 via a delay circuit 12. A mode discrimination circuit 9 applies frequency detection to an RF signal VI to discriminate whether the signal system is a recording mode at a wide band or that at a narrow band. A switch element 15 is subject to switching control by a signal from the mode discrimination circuit 9 and a delay time of the delay circuit 12 to the input signal is set to a prescribed value in response to the mode. Thus, since the demodulation sensitivity is switched in response to the frequency band occupied by the signal, the amplitude of the demodulation output is made nearly constant independently of the deviation, and a means to adjust the amplitude after demodulation is not required.

Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To make performing parallel operation and control in the same sense possible, reduce the required number of cables, and decrease wiring error of the cable and cross talks by reading data, serially transferring the data, and repeating cycles in a high cycle that a person cannot sense. SOLUTION: A CPU 3 reads binary code data of a console 14 in an IC 13, and serially transfers it to an IC 6 of an interface 5 through a signal cable 9, then the data is taken in the CPU 3. A series of the operations is repeated in high speed cycles of 20-50msec. that a person cannot sense. In spite of the serial transfer of data, switch operation and driving part control are operated as if parallel control of one to one correspondence without feeling time delay. Even if the number of switches of the console is increased, by increasing the number of ICs of an interface, data can be transferred without increase in the number of signal cables 7, 8, 9, 11.

Filed: 1989-01-20
Abstract: PURPOSE:To allow a smaller size and a lower cost by so arranging an end face of an optical fiber as opposed to a surface facing an object to be worn of a block body. CONSTITUTION:When an internal surface of a surrounding wall (b) of an object B to be worn is made to wear with a high speed reciprocation within the object B of a cylinder head D with a rod C, a block body 1 of a wear sensor A wears. Optical fibers 3a, 3b... 3h arranged within the block body 1 have reflection films 13a, 13b... peeled off being worn from a position closer to a tip face 12 of the block body 1, namely, in the order of the fibers 3a, 3b.... Then, light made incident from a light source fails to be reflected with the reflection films 13a and 13b... and portions of the fibers 3a, 3b... where the reflection films 13a, 13b... are peeled off do not come to be detected with a photodetector. Thus, this makes it clear that the internal surface of the surrounding wall (b) of the object B to be worn wears to array dimension positions of the fibers 3a, 3b... thereby enabling the learning of a degree of ware of the internal surface of the surrounding wall (b) of the object B to be worn.

Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To enlarge the surface area after etching and increase the capacitance by arranging protuberances whose heights fulfill a specified range in a zigzag form on the surface of an aluminum foil, and limiting the intervals between the protuberances to the specified range. SOLUTION: A material of 99.90% or over is used as the aluminum foil base material. Protuberances 2 about 0.95-10μm in height H are arranged zigzag alternately at intervals λ of about 0.1-20μm on the surface of this aluminum foil 1. With this, pit density is maximized, and the capacitance is increased. Moreover, for the recess 4 surrounded by the three apexes of the protuberances 2, pits are grown only in the vertical direction <100> so as to suppress the dissolution in the horizontal direction <100>, at the time of etching. Hereby, an aluminum foil which can surely get high capacitance can be manufactured.
