Title: Current control equipment of inverter
Inventor: FUJII SHUICHI
IPC: H02P21/22
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a current control equipment of an inverter which attains noise reduction and quick response, by judging the use of a filter according to whether large noise is contained in a signal. SOLUTION: This current control equipment is provided with a comparing means 11 and a switching means 12 of a current feedback value. The means 11 compares the change amount of a current detection value iq detected by current detectors 3, 4 with the change amount of a current command value iq *. The means 12 uses a current signal value averaged by using a filter 7 as a feedback value to the current command value iq * when the change amount with time of the current detection value of iq is large as compared with the change amount with time of the command value iq *. The means 12 uses the current detection signal, as it is, as the feedback value to the current command value iq * when the differance between the change amount with time of the current command value iq * and the change amount with time of the current detection value iq is small.

Title: Method and device for scheduling job shop
Inventor: YAMADA TAKESHI
IPC: G06Q50/04
Filed: 1995-05-22
Abstract: PURPOSE: To quickly obtain a quasi optimum solution capable of minimizing total working time by generating a new individual by genetic algorithm using critical block neighborhood for two individuals selected from an individual group and searching local neighborhoold. CONSTITUTION: When an initial individual group generating means 102 generates the initial value of a group being the set of individuals to be used for genetic algorithm, a two-individual selecting means 103 selects two individuals by biasing so as to easily select individuals more excellent than the initial individual group or an individual group on the way of processing. A multi-stage crossing means 104 applies multi-stage crossing to the two selected individuals to generate a new individual. A local neighborhood searching means 104 calculates critical block neighborhood for the individual group generated by the means 102 and the individual generated by the means 104 and substitutes the most excellent individual in the critical block neighborhood for the original individual. Consequently an excellent solution for a large-scale problem can be quickly found out.

Title: Method of detecting knocking in internal combustion engine
Inventor: TAKEDA YUUJI
IPC: G01M15/00
Filed: 1981-08-07
Abstract: PURPOSE:To enable knock in high speed rotation of an engine to be controlled by controlling ignition timing when detected value of rotational frequency of the engine is larger than a predetermined value even if a knock sensor generates small knocking indicating signals, similarly to when large knocking indicating signals are generated. CONSTITUTION:In a crank angle wherein electric signals from a knock sensor 12 produce only mechanical vibration caused by valve blows or the like other than knocking without the occurrence of the knocking, the output amplitude b from the knock sensor 12 is taken out as background signal and multiplied by predetermined factors k1-k2, for example, k2=2k1 to provide judgement level of larger or smaller knock. Since these (b), (k1b), (k2b) change together in response  to the rotational frequency of an engine, a point P for example represents small knocking between b and c as viewed from the output of the sensor 12. However it represents actually large knocking since it exceeds d. Thus, a control circuit 20 controls ignition timing even when the signals of the knock sensor 12 represent small knocking in high speed rotation of the engine, as well as when they represent large knocking.

Title: Fixing device
Inventor: OTSUKA YASUMASA
IPC: B32B1/08
Filed: 1990-05-15
Abstract: PURPOSE:To restrain the occurrence of triboelectrification and to obtain excellent releasing property in the long term by allowing a pressure roller to have an elastic layer on a conductive core bar and forming a surface layer consisting of a conductive PFA tube on the elastic layer. CONSTITUTION:Rubber 13 which is made conductive by surfactant, metallic powder and carbon powder, etc., is used as the elastic layer and the conductive PFA tube 18 is attached on the surface of the layer. Since the conductive PFA tube 18 is provided on the surface layer of the pressure roller 2, the releasing property of the surface is maintained even in the case of using the roller in the long term. Because the tube is conductive, charges are not accumulated on the surface layer and move to a conductive core bar 17 through the elastic layer 13, thereby preventing offset.

Abstract: PURPOSE:To enable measurement of a diameter of a hole to be measured in non-contact and non-destructive manners, by a method wherein a hole to be measured is irradiated with a measuring light with wavelength varied sequentially to detect the cut-off frequency of said hole to be measured and a bore diameter is measured from frequency. CONSTITUTION:A hole 6 to be measured of a sample 7 placed on an X-Y table 13 is irradiated with a measuring light 8 from a light source 2. Reflected light from the sample 7 is detected with a photosensor 10 with selection wavelength of a wavelength selector 3 altered sequentially from short to long and a detection output thereof is inputted into an arithmetic device 12. The arithmetic device 12 judges a wavelength with a light intensity output failing to change as detected with the photosensor 10 to be the cut-off wavelength. Thus, a diameter of said hole to be measured is calculated from a correlation between the shielding wavelength and the diameter of the hole to be measured.
