Patent JP-2000262083-A (JP)
Title: Brushless dc motor drive controller
Inventor: CHIN SATOSHI
IPC: H02P6/06
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To suppress a stepwise waveform from being generated at an output torque waveform by limiting a period for supplying drive current by pulse- duration modulation (PWM) to an OFF-phase so that residual current in an OFF-phase of a commutation phase in an exciting coil may become zero, thereby reducing the OFF-phase residual current generated in commutating to zero. SOLUTION: This controller computes such an exciting period that the initial value of exciting current id at the beginning of commutation is set to zero based on a time constant with inductance Lm and resistance R, the Duty 2 of a drive signal PWM, counter electromotive force Ed, DC line voltage Vb or the like in the equivalent circuit of an OFF-phase coil in commutating. Current supply to the OFF-phase is completely set to OFF other than the exciting period. The residual current of the exciting current id in commutating is set to zero to form the waveform of output torque into a stepless and continuous waveform, thus it is possible to reduce the oscillation and noise of a motor at the time of low-speed rotation.

Title: Pattern forming material and formation of pattern
Inventor: MORITA MASAO
IPC: G03F7/038
Filed: 1984-04-06
Abstract: PURPOSE:To obtain a material high in sensitivity to high energy rays and resolution, and in resistance to dry etching by incorporating a specified silicone polymer. CONSTITUTION:The material high in sensitivity to high energy rays and resolution is obtained by introducing a photosensitive group X into a silicone polymer having di- or mono-substd. siloxane structures as the skeleton of the main chain and phenyl grups on the side chains. Further, the introduction of the mono- substd. siloxane structures into the main chain realizes a branched structure or a ladder structure, enhances resistance to oxygen dry etching by the high content of silicon, and elevates a glass transition point. Since this material is solid at room temp., and high in flexibility due to the siloxane bonds in spite of the presence of the branched or ladder structure, it is soluble in many org. solvents, and a superior coat film can be obtained by spin coating a base or the like method.

Title: Optical writing printer
Inventor: SUMIYA SHIGEAKI
IPC: G03G15/047
Filed: 1986-03-26
Abstract: PURPOSE:To attain gradation expression in each dot independently of the size of a gamma value of a photosensitive body by adding a specific auxiliary exposure to exposure in an optical writing part. CONSTITUTION:The optical writing part obtained by combining an LED array 1 with a SELFOC lens array 2 is separated from an auxiliary exposure part obtained by combining a fluorescent lamp 3 with a density screen by a douser 5. A photosensitive body 6 is moved so as to be exposed by both the optical writing part and auxiliary exposure part. The pitch of density change on the screen 4 in the direction rectangular to the moving direction of the photosensitive body 6 is made to coincide with the dot pitch of the optical writing part and the density of a part corresponding to one dot in the same direction is different on the center part of the dot and its peripheral part. Thus, area gradation type half tone coloring can be obtained independently of the gamma value of the photosensitive body 6 by superposing the exposure of the optical writing part to the auxiliary exposure.

Title: Signal voltage dividing circuit
Inventor: FUKUSHIMA ISAO
IPC: H03H19/00
Filed: 1981-05-08
Abstract: PURPOSE:To realize a signal voltage dividing circuit of high resistance and high accuracy within an IC, by incorporating plural units of equivalent resistances composed of the switch capacity within an IC and clearing the method of the equivalent combination. CONSTITUTION:The clock signal is applied to either one of the switches 7 and 14 via an inverter 16 in order to open and close these two switches with the phase opposite to each other. A capacity 17 is neglected in terms of a low frequency, and the voltage generated at a terminal 4 is divided by resistances R1 and R2. Thus the capacity 17 has only to hold the preceding voltage when the switches 7 and 14 are connected to the contacts 18 and 21. The voltage can be theoretically reduced at will as long as the time constant defined by the value of the capacity 17 and the value of a load resistance 11 has a sufficiently large range to the clock period. And the voltage division ratio can be decided by the capacity ratio between the capacities 8 and 15.
