Title: Power-converter device
Inventor: IKEDA KATSUMI
IPC: H02M7/12
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for detecting a counterelectromotive power vector and simplify selection of a switching mode by selecting either switching of a voltage switching mode so that a current deviation vector is directed in a direction within a specific boundary and transmitting it to a power converter. SOLUTION: A current deviation vector is detected from current deviations ΔiU, iV, and iW by a current deviation vector detection circuit 802. Then, an annular boundary where distance from its zero point is determined corresponding to the accuracy of current control is set onto voltage vector coordinates. When a current deviation vector with a zero point as a start point is within and outside the boundary, no-voltage switching mode and an applied voltage switching mode where the direction of the voltage vector out of the voltage switching mode is closest to the direction of the current deviation vector are selected by a switching mode selection means 81, respectively, and are transmitted to the power-converting device, thus easily selecting the switching mode.

Title: Temperature controller for copying machine
Inventor: TAMAGAKI HIKARI
IPC: G03G15/043
Filed: 1989-05-17
Abstract: PURPOSE:To accomplish temperature control in response to a condition regardless of the change in outside air temperature by detecting a change in the ambient temperature of an original platen. CONSTITUTION:A first sensor S1 which detects the ambient temperature of a light source which irradiates an original on an original platen with a light, a second sensor S2 which detects the ambient temperature of a paper feeding part and an operation inhibiting means 21 which inhibits a copying operation when temperature detected by the sensor S1 rises by prescribed value of temperature or more rather than temperature detected by the sensor S2 are mounted. The ambient temperature of the paper feeding part approaches the outside air temperature and a rise in the ambient temperature of the original platen is obtained from a difference between the ambient temperature of the original platen and the ambient temperature of the paper feeding part. Therefore, a heating condition by a copying lamp is informed regardless of the change in the outside air temperature and when the heating quantity grows, the copying operation is inhibited. Thus temperature control which is not affected by the change in the outside air temperature is performed.

Title: Manufacture of synthetic resin molding material
Inventor: OTONARI NOBUYA
IPC: B29B11/16
Filed: 1987-05-22
Abstract: PURPOSE:To directly control impregnated state and consequently prevent the impregnated state from fluctuating and poor impregnation from occurring by a method wherein glass roving is impregnated with compound in advance and, after that, cut at the manufacture of synthetic resin molding material, which is produced by impregnating chopped strands with the compound. CONSTITUTION:Glass roving 3 is passed through a compound tank 10 so as to surely impregnating the glass roving 3 with compound by means of impregnating rolls 11 and taken out of the compound tank 10. Next, excess compound is removed from the roving by means of rolls 12 and the like. The resultant roving is transferred to a cutter roll 9 so as to be cut. Since chopped strands are covered with the compound at the early stage of impregnation, air a2 mixed at impregnation apparently clings to the chopped strands 6. However, since the wattability between the chopped strand 6 and the compound 4 is good, the air a2 behaves as air a1, which mixes with the compound in such a manner as affecting no generation of pin holes.

Likewise, when the gauge signal is outputted during ongoing grinding to a point L3 from the point L2, it is reset to a Z-axis coordinate position at the time of cycle starting after the grinding goes up to the point L3, thus the fixed cycle is over. Likewise, when the gauge signal is outputted during infeed from the point L3 to a point L4, the infeed is suspended at the position, the grinding is carried out up to the Z-axis coordinate position at the time of cycle starting from this position, making the fixed cycle come to an end. In addition, when the gauge signal is outputted during grinding from the point L4 to a point L5, the grinding is continues to the extent of the point L5 as it is, making the fixed cycle come to an end as well.
