Signals I and Q which differ by π/2 phase, which are inverse Fourier-transformed and outputted, are supplied to orthogonal modulation circuits 12, 22 and 33 and they are orthogonally modulated. Signals which are frequency-transformed by using frequencies fa, fb and fc are band-restricted by band-pass filters(BPF)16, 26 and 36. Then, a signal synthesis circuit 17 synthesizes the signals of the respective groups. Thus, the number of points of IFFT can be reduced, the speed of the signal itself is reduced, and the margin of circuit design can be taken to be large.

After that, without using the chemical treatment of dissolving the metallic foil other than the adhesion of circuit pattern, the unnecessary metallic foil is exfoliated by such a physical means as to tear the metallic foil at the not directly stuck part from the insulating board, or the like. The force of exfoliation is at a level of not doing damage or breakdown to a circuit board, and there is no necessity of sticking to the numeric value itself, depending upon the junction rate between the metallic foil and the circuit pattern and the adhesion degree of the circuit pattern.

Title: Laser beam printer
Inventor: OKUBO MASAHARU
IPC: G03G15/04
Filed: 1984-11-16
Abstract: PURPOSE:To stabilize a picture quality by controlling a laser output in correspondence to the temperature of a semiconductor laser. CONSTITUTION:In a semiconductor laser 18, a photosensor 27 such as a photodiode is installed at the opposite side to the outgoing radiating side of the beam for scanning the sensitive body of a laser chip, and connected to a controller 25. The photosensor 27 receives the light of the rear surface of the laser chip and detects a light quantity, and adjusts the laser driving electric current so that the photodetecting quantity can be constant by the controller 25. Consequently, when the wavelength of the laser beam due to the temperature change around the semiconductor laser is changed, the laser output is corrected in correspondence to the temperature change and the surface electric potential of the laser beam exposure part of the laser beam of the sensitive body is kept constant, and therefore, the stabilized picture quality can be obtained.

Abstract: PURPOSE:To remove obstruction which hinders screen viewing and not to disturb automatic focusing function by constituting in such a way that light passed through an original is reflected from a semitransmissive mirror in order to be projected onto a screen and a viewer can watch display on the screen through the semitransmissive mirror. CONSTITUTION:The light passed through the original 7 is projected onto a screen 14 via both projecting lens 10 and mirror 11. The mirror 11 is semitransmissive mirror, and reflects the light passed through the original 7. And an overhead projector is constituted in such a way that a screen viewer can watch the screen 14 through the mirror 11. The overhead projector 1 has an automatic focusing mechanism; the light of a light source for automatic focusing detection is reflected in a different position of the mirror 11 from the light passed through the original. Thus, the image of the original can be projected onto the screen, and the viewer can clearly watch the picture on the screen from the rear without being hindered by the mirror.

Title: Oxide superconducting current-limiting element
Inventor: TSUBOUCHI HIROKAZU
IPC: H02H9/02
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to, if any short-circuit fault occurs, limit short- circuit current at high speed with a small-sized element. SOLUTION: An oxide superconductor 1 is anisotropic in the direction in which a main lead wire 2 is connected and in the c-axis direction perpendicular thereto. Control lead wires 3 are connected to the end faces of the said oxide superconductor 1 in the caxis direction. One of the control lead wires 3 is connected to the main lead wire 2 in the stage precedent to the oxide superconductor 1, and the other control lead wire 3 is connected to the main lead wire 2 in the stage following the oxide superconductor 1. Thus current branching from the main lead wire 2 is let through the oxide superconductor 1 in the c-axis direction. If an excessive current is passed through, this brings the oxide superconductor 1 in normal conduction at high speed, and limits the current with a resultant resistance.

Title: Manufacture of semiconductor device
Inventor: KATO SHINYA
IPC: H01L21/027
Filed: 1989-09-18
Abstract: PURPOSE:To form a positive type electron beam resist layer for exposure in even sensitivity distribution, resolving power and excellent dry etching resistance by a method wherein the pre-baked positive type electron beam resist layer is slowly cooled down. CONSTITUTION:Since pre-baked positive type electron beam resist is slowly cooled down until at least reaching the glass transition temperature, thereof, the molecular weight of the resist layer is increased larger than that in case it is rapidly cooled down resultantly enhancing the dryetching resistance thereof. Besides, the sensitivity of the positive type resist is decreased by increasing molecular weight so that the effect of any scattered electron beam in the edge part of drawn pattern and the thermal effect during the drawing process may be lessened. Furthermore, the cooling rate in the substrate surface coated with the resist layer is equalized by the slowly cooling down process. Consequently, the sensitivity of the resist layer, the dryetching resistance and the distribution of the resolving power on the substrate surface are made uniform.

Title: Electronic apparatus with protective device against service interruption
Inventor: NAKAMURA NORIKAZU
IPC: H02J9/06
Filed: 1990-09-12
Abstract: PURPOSE:To protect an electronic apparatus against a momentary service interruption of several tens of milliseconds to several seconds by providing means for detecting the service interruption for an AC load and a DC load, operating a switching unit based on a command of control means when the service interruption is detected, and connecting the input terminal of the load to a power supply terminal of a protective storage battery against service. CONSTITUTION:When a momentary service interruption occurs, the service interruption state is sensed by an Ac service interruption detector 15, and a sense trigger signal is output. A controller 12 inputs the signal to know the momentary service interruption, and outputs a control signal for instructing switching to a switching unit 11. When the unit 11 inputs the control signal, it applies a switching signal 10 to changeover switches 6, 7 under the condition that a switch 13 is closed. Thus, the switch 6 is connected to terminal 6b, and the switch 7 is connected to terminal 7b. Thus, even if the momentary service interruption occurs, similar operation to that before the power interruption is executed during several tens of milliseconds to several seconds.
