Filed: 1986-07-07
Abstract: PURPOSE:To very easily and exactly execute incidence and emission by constituting the titled element so that the incidence of a fundamental wave and the emission of the second higher harmonic is executed by a diffraction grating of the surface of a substrate.

Title: Current controlling device for electric power converter
Inventor: OOMAE TSUTOMU
IPC: H02P7/292
Filed: 1981-10-05
Abstract: PURPOSE:To stably control load current with high response by connecting a current variation controlling circuit to a current controlling circuit controlling the average value of load current in parallel. CONSTITUTION:When a current command value IMC is increased, a current controlling circuit 5 outputs a current rate command value IRC. A current rate controlling circuit 7 outputs an arc angle command alpha based upon the difference between the current rate command value IRC and a current variation value IRF during an arc pulse period. A gate pulse generating circuit 9 applies arc pulses to thyristors S1-S6 in an electric power converter 1 at an arc angle in accordance with the command alpha, so that current I is increased while pulsating and mean current value IM outputted from a filter 6 is also increased. Since a current variation detecting circuit 8 detects the current variation value IRF instantly in every generation of an arc pulse, current control can respond at a high speed. A current rate controlling system speeding up the changing direction of current I is connected as a minor loop, so that stable control is made possible even if the gain of the circuit 5 is increased.

Title: Finder for camera
Inventor: NAKAI ETSUKO
IPC: G03B13/14
Filed: 1989-06-22
Abstract: PURPOSE:To prevent a finder size from being scaled up by allowing one means to simultaneously correct parallax and diopter. CONSTITUTION:Parallax in macro-photographing when a finder optical system is provided above a photographing optical system arises because an image is formed above a normal image forming position. When a fourth reflecting plane is moved downward so that the image forming position is moved down by as much as the parallax, the parallax arising when photographing can be corrected. On the other hand, the dislocation of diopter can be prevented in such a way that only the length of an optical path between an objective lens 5 and the image forming plane is corrected to correspond with the longer distance. By moving the fourth reflecting plane 4, a distance between a third reflecting plane 3 and the fourth reflecting plane 4 becomes shorter to shorten the length of the optical path. Consequently, the parallax and the dislocation of diopter can be simultaneously corrected by moving the reflecting planes 1 to 4. As a result, the scaling-up of the finder can be prevented.
