Title: Speed controller for moving body
Inventor: TAJIMA FUMIO
IPC: H02P6/10
Filed: 1988-06-06
Abstract: PURPOSE:To reduce an irregular rotation by altering the gain of speed control in response to the magnitude of a speed error amount. CONSTITUTION:A speed controller C for a brushless motor M of a moving body controls the motor M having a pole position detector PS and a speed detector E made of an encoder or the like. The controller C is composed of a microcomputer MC, a speed detector COUNT, an automatic current regulator ACR, and a driver INV, the microcomputer MC is composed of a calculator MPU, a ROM, a RAM, and a DAC (analog/digital converter), and its output is input to the regulator ACR. Further, means for calculating a novel speed error amount and altering the proportional gain of a speed control system in response to the error amount is provided. An irregularly rotating amount is grasped by the speed error amount obtained by the values of two or more past speed errors, and the gain of speed control is varied on the basis of it. Thus, it is adapted for a VTR and the like to be requested for a high constant speed property.

Abstract: PURPOSE:To reduce noises generated on a power supply line on the change-over of output levels from output buffers by mounting power supply busses at every fixed number of the output buffers in an integrated circuit with a plurality of the output buffers. CONSTITUTION:Output buffers 206-1-1-206-Q-P in an integrated circuit chip 202 held to a package 201 are divided into the groups of Q pairs consisting of P output buffers.

Title: High-dimensional optical element array and super-parallel optical interconnection
Inventor: INOUE HIROAKI
IPC: G02F3/00
Filed: 1992-05-29
Abstract: PURPOSE:To provide the large scale parallel optical element array which enables large scale flexible connection, and a system provided with a novel function for super-parallelly interconnecting those optical elements. CONSTITUTION:The number of the address dimensions of optical signals can be increased by combining a spatial optical switch 2 for spatially realizing the interconnection and a frequency type optical switch 3. Thus, the number of optical signal elements to be handled can be equivalently increased without enlarging the physical scale of optical elements. Since not only the dimension of a frequency but also the dimension of a frequency and polarization can be used for increasing the number of dimensions, the capacity of the interconnection can be considerably enlarged. Therefore, the scale of the array can be equivalently and considerably enlarged with the small sized optical elements having the spatially small array scale.

Title: Discharge device for solid substance inside drum
Inventor: KAJIYAMA TAKAO
IPC: B65G65/46
Filed: 1979-10-25
Abstract: PURPOSE: To assure safety of operation, automation and improved efficiency by scraping out solid substance from inside the drum with the assistance of rotary screw having proceeding/receding mechanism.  
     CONSTITUTION: Drum 1 is carried to drum-fixing device 3 with the help of roller conveyor 2 and is held between pneumatic cylinder for fixing 4 and holding arm 13. Following this procedure, pneumatic cylinder for rollover 5 contracts to roll over the drum 1. When screw 6 rotates, pneumatic cylinder for insertion 10 is extended. Screw 6 advances rotating into drum 1 and scrapes/transfers solid substance to the outside by means of spiral impeller. Next, cylinder for insertion 10 recedes to contract, causing truck 7 to go back. As a result, screw 6 pulls out of drum 1. Thus almost no labor is required because scrap-off operation is unnecessitated, thereby contributing, toward the solution of safety problem.
