IPC: B41J2/44
Filed: 1982-09-10
Abstract: PURPOSE:To hold a superior print quality, by adjusting the gain of a driving circuit to improve the diffraction efficiency in a laser printer. CONSTITUTION:A detecting circuit 7 detects the maximum value of a laser beam which a photodetector 65 receives, and a control circuit 8 discriminates the value of a gain adjustment input, which an input generator 5 generates when the circuit 7 detects the maximum value, and controls the input generator 5. A reflective mirror 64, the photodetector 65, and the circuit 7 constitute a means which detects the maximum value of the beam transmitted through a slit 31 in a fixed position before scanning of a rotary drum 63. The gain adjustment input having various values is generated from the input generator 5 to change the characteristic curve of a driving circuit 4 within the range indicated in Fig. by dotted lines, and the timing signal of modulation is used to detect the maximum value of the beam, and thus, the beam is deflected with the highest diffraction efficiency by an optical deflecting system 2.

Title: Optical recording medium, its recording reproducing method, and manufacturing method of master stamper
Inventor: UENO FUMIAKI
IPC: G11B7/24085
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain a high density recording medium with stable characteristics by forming a recording film having equal characteristics in and between the grooves. SOLUTION: This optical information recording medium is equipped with two kinds of grooves G, L being alternately adjacent and different in depth. Since both are grooves, difference in a film thickness scarecely arises when the film is formed, making it possible to form a recording film of the same structure. In addition, the shape on both sides of the grooves are identical, thereby making recording characteristics identical between the grooves G, L. There is no need of purposely shifting the width between the grooves in order to relax the difference in the recording characteristics; therefor, the use of this substrate can improve recording density. Moreover, as the recording film can be evenly formed, stable manufacturing is possible for the optical information recording medium.

IPC: F21S8/02
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To assure a large horizontal rotating range for a lighting fixture, lessen the number of component parts, and enhance assembling operability of works. SOLUTION: A luminaire 3 includes a lighting fixture 4 supported by a support member 5 in such a way as to be rotatable horizontally and is configured so that a pair of a stoppers 8 and 10 capable of abutting to each other for hindering the lighting fixture from the horizontal rotation exceeding a specified angle are installed on the lighting fixture 4 and support member 5, respectively, wherein the arrangement includes a mounting part 11 where the stopper 10 on the side with the member 5 is rotatable, i.e., a constant range in the same direction as that of the horizontal rotation of the lighting fixture, a protruding part 12 capable of abutting to the stopper 8 on the side with the lighting fixture 4, and a resilient part 13 for holding down the peripheral surface of the lighting fixture 4.  This enables lighting fixture to rotate horizontally by 360 degs. or more, and no dead angle will exist within the range of irradiation. Because the protruding part 12 and resilient part 13 are formed on the same stopper 10, a single piece of component part as a horizontal rotation stopper can work both to suppress the horizontal rotation due to vibration and to prevent plays.
