IPC: H03K9/02
Filed: 1980-12-30
Abstract: PURPOSE:To achieve the conversion of sampling frequency and data operation between sampling data of different sampling frequencies, by interpolating point of time other than sampling points of the sampling data.

Title: Membrane separator for water treatment
Inventor: ISHIYAMA KAZUHIRO
IPC: C02F1/44
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To accurately detect the clogging degree of a membrane by calculating an amt. of transmitted water in terms of reference differential pressure and reference temp. from the amt. of transmitted water detected by a transmitted water amt. detection means. SOLUTION: At first, an amt. of transmitted water is calculated from the detection value of a flowmeter F-1 and the membrane area of a membrane module 4. Then, the amt. of transmitted water under a reference condition is calculated in terms of reference differential pressure and reference temp. from the respective detection values of pressure gauges P-1, P-2, P-3 and the viscosity calculated from the temp. detected by a thermometer T-1 and the future amt. of transmitted water under the reference condition can be estimated from the transition of this calculated amt. of transmitted water. Therefore, the amt. of transmitted water under the reference condition necessary for chemical washing is preset and, when the amt. of transmitted water under the reference condition lowers to this set value, chemical washing is performed to make it possible to perform chemical washing corresponding to the state of a membrane. Since the lowering of the amt. of transmitted water under the reference condition can be easily estimated, a chemical washing period can be easily estimated and the operation control of the apparatus becomes easy.

Title: Feed speed controller
Inventor: FUJITA JUN
IPC: G05B19/416
Filed: 1988-07-27
Abstract: PURPOSE:To smoothly operate a mechanical system to improve the efficiency of production and to reduce the burden on a programmer by judging a position where acceleration/deceleration is required and performing the acceleration/deceleration processing in this position. CONSTITUTION:A decision part 15 obtains accelerations ¦DELTAXN-DELTAXa¦ and ¦DELTAYN-DELTAYa¦ generated in respective axial directions in accordance with movement extent components DELTAXn and DELTAYN finally stored in a storage part 5 and movement extent components DELTAXa and DELTAYa calculated by a first interpolating part 3 and compares them with the value of an allowable acceleration ACp; and when either of said accelerations is larger than the value of the allowable acceleration ACp, the decision part 15 outputs an acceleration request signal IR and a deceleration request signal DR top an acceleration command part 17 and a deceleration command part 19 respectively and does not output movement extent components DELTAXa and DELTAYa calculated by the first interpolating part 3 in the storage part 5 but outputs a signal DN to execute interpolation again. Since a device judges the position, where acceleration/ deceleration is required, to perform acceleration/deceleration in this manner, it is unnecessary for the programmer to judge whether acceleration/deceleration is required or not at the generating the working program, and the burden on the programmer is reduced.

Title: Controller for ultrasonic motor encoder
Inventor: TSUKIJI MASAAKI
IPC: G02B7/08
Filed: 1993-06-30
Abstract: PURPOSE:To prolong the life of a light source of an encoder without causing any distortion in a device on which the encoder is mounted by cutting a power source in an optical type encoder at the stoppage of an ultrasonic motor to reduce the generation of heat from the encoder itself to the minimum. CONSTITUTION:In an ultrasonic motor encoder 1, an optical type encoder 102 is integrated with an ultrasonic motor 101 into one body. When the motor 101 is driven to supply power, a control means 7 turns on a power source 4 to operate the encoder 102 and the position or a speed signal 101 of the motor obtained are taken into a signal processing circuit 6. Then, the results of a signal processing from the circuit 5 are inputted to control the motor 101 through a drive circuit 6. Then, when the motor 101 is stopped, the means 7 turns off the power source 4 to cut the supply to the power source 4 to the encoder 102. This minimizes the generation of heat to eliminate distortion and thermal imbalance as caused by heat generated, thereby, the life of the light source of the encoder 102 can be extended.

Title: Accelerator operation resistance generating device
Inventor: YAMAGUCHI SHINYA
IPC: F02D11/02
Filed: 1995-06-30
Abstract: PURPOSE: To generate frictional resistance at rotating time, and add resistance force to accelerator operation by installing a cam whose outside peripheral surface is formed as a friction cam surface on a rotary shaft, and elastically butting a push-pressing member against the friction cam surface. CONSTITUTION: When an accelerator pedal 20 is stepped, an accelerator lever 14 and a rotary shaft 9 integrally formed with this rotate in the clockwise direction. At this time, a push-pressing member 31 butted against a friction cam surface 27 by a spring load of a compression spring 34 imparts frictional resistance proceeding backward in rotation to a cam 25. Since the friction cam surface 27 rotates in the direction for compressing this by opposing a spring load of the compression spring 34 in a butting place, frictional resistance is large, and this increases stepping force of the accelerator pedal 20. As a result, even in an automobile mounted with an electric transmission system, accelerator operation can be performed with stepping force in the same degree as a mechanical transmission system using a huge wire cable without a sense of incompatibility.
