Title: Printer
Inventor: FUKUSHIMA TAKAFUMI
IPC: B41J2/305
Filed: 1985-04-12
Abstract: PURPOSE:To enable high-speed operation and reduce noise by forming a driving part with a magnet and an armature, making the armature electrically conductive and integrally providing a needle member with low specific gravity substance. CONSTITUTION:If a printing signal is given to a magnet 16, a core 18 is excited, attracting an armature 23 and rotating a movable member 22. A needle 25 advances toward an opposed electrode 5 by the rotation of the movable member 22, and its distance to the opposed electrode 5 becomes short. As a result, an electric field between the needle 25 and the opposed electrode 5 is intensified, and an ink 10 adhering to the tip 26 of the needle 25 is sent flying toward the opposed electrode 5 by a static power. Then ink droplets stick to a recording paper 6 to form dots. As a needle member 24 is formed of low specific gravity material, its inertia is insignificant and it follows a high-speed motion if subjected to said motion. Besides, the collision energy of a stopper 28 or the core 18 is small, thus reducing a noise.

Filed: 1992-03-31
Abstract: PURPOSE:To suppress mutual diffusion and form a steep impurity profile by interposing an impurity absorbing layer between a first semiconductor layer and a second semiconductor layer. CONSTITUTION:After the epitaxial growth of an n-type indium phophide (Ink) layer 11 doped with silicon as an n-type impurity at a low concentration in the surface of a semiconductor substrate, SiH4 or Si2H6, a silicon dopant, is supplied to the surface of the n-type InP 11 for fixed time with the substrate being put in a standby state while kept at a growth temperature, thereby forming a silicon-containing layer 12. Then, a p-type InP layer 13 having a Zn (a p-type impurity) concentration lower than the silicon-containing layer 12 is grown. Thus, the p-type InP layer 13 of a desired film thickness is formed. Although Zn has a diffusion coefficient larger than Si, an n-type impurity, the diffusion of An which is a p-type impurity stops at the Si-containing layer 12 because of the existence of the Si-containing layer 12.

Title: Exciting timing setting method for stepping motor
Inventor: KAI TAKAYUKI
IPC: H02P8/36
Filed: 1982-05-12
Abstract: PURPOSE:To prevent an overshoot of a stepping rate by replacing part of a pulse interval of exciting timing to be applied when the constant acceleration of a stepping motor is finished by a pulse interval obtained for a low speed of the motor. CONSTITUTION:The number of times of continuing the pulse of the same pulse interval is set to odd number. In other words, when the number is even in a conventional approximating method of the exciting timing, it is converted to odd number by adding or subtracting 1 to or from the continuous number. Then, the pulse interval of the even number is returned to the pulse interval before generating continuous number of the pulse interval of the even number. Since the rotation of the motor immediately before reaching the constant speed fs is accelerated while repeating the accelerating and braking in this manner, an overshoot of stepping rate in theory of speed displacement at the accelerating time is prevented, and the vibration of the motor can be reduced at the accelerating and constant speed times.

Abstract: PURPOSE:To increase a processing speed by converting a received signal from analog to digital and then dividing it into plural frequency bands by digital filters, and lowering their rates to necessary data rates by data thinning out filters and inputting the signals to a memory. CONSTITUTION:A received signal which is reflected by the surface of the sea and received by a receiver is sampled and quantized by an A/D conversion part 1. Then the output digital signal of the conversion part 1 is divided into the four frequency bands by the 1st-4th digital filters 2-5. Then the outputs of the filters 2-5 are passed through 1st-4th data thinning out filters 4-9 so as to lower their data rate to the data rates matching with the respective band widths. Consequently, the signals of the respective bands which are lowered to the data rates are multiplexed and stored in the input memory 10. The data stored in the memory 10 is transferred, band by band, to a Doppler filter 11 to generate filter banks by Fourier transformation, thereby dividing an observation area. Thus, the processing speed is increased.
