Patent JP-H09270618-A (JP)
Title: Antenna system
Inventor: FUKAZAWA TORU
IPC: H01Q1/46
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve the performance of the antenna by providing throughholes connecting 1st and 2nd ground conductor patterns in the vicinity of open ends of 1st and 2nd notches and forming a slot folded to be U-shaped to a multi-layer circuit board with the 1st and 2nd notches and the throughholes so as to realize the tolerance of the size of an antenna support structure. SOLUTION: Two conductor plates 3 each having a notch 2 whose electric length is 1/4 wavelength or below with respect to the operating frequency and whose width is sufficiently smaller than the wavelength and throughholes A4 connecting the conductor plates 3 form a half wavelength slot folded to be U-shaped. In this half-wavelength slot, the resonance mode is stimulated where the electric field is maximum at the end of the notch 2 toward the throughholes A and zero at the other end by a voltage source 5, and an electromagnetic wave is emitted in this mode. The occupied volume or area of the antenna is decreased through the provision of the slot folded to be U-shape and the antenna system with a small size at a low cost is realized.

Title: Copying device with variable power
Inventor: TAKEMURA YUKIO
IPC: G03B27/34
Filed: 1983-04-30
Abstract: PURPOSE:To execute a black erasing exposure corresponding to a continuous variable power copying by only one light source by fixing an image forming lens and a black erasing exposing light source so as to be operated in one body, and also varying continuously its light irradiating range. CONSTITUTION:A black erasning exposing light source 10 is fixed to an optional part except a lens surface of an image forming lens 2, so as to be operated in one body with the lens 2. A projecting part 12 is provided on one edge of a light shielding member 11 so that a light irradiating direction from the light source 10 is limited to a photosensitive drum side. A grooved part 13 is formed by deriving a locus along which the projecting part 12 moves. The projecting part 12 is attached to the groove part 13 so as to be slidable. Also, a black erasing exposure control part 14 for controlling an advancing direction of an edge part L of a light from the light source 10 is formed on the light shielding member 11 so as to be positioned between the light source 10 and the photosensitive body surface. In case when the lens 2 moves in accordance with the copying magnification, and an exposure range of an original image on the photosensitive body is narrowed, a relative position of the lens 2 and the light source 10 is not varied, but the projecting part 12 moves along the grooved part 13, therefore, the light shielding member 11 and the control part 14 also move following it, and in the end, the black erasing exposure range is expanded and the black erasion is executed to a desired area.

Abstract: PURPOSE:To decide an end point with high precision by providing a process, in which the end point is decided by the quantity of electricity after amplified offset, and a process in which the quantity of electricity and a fixed value are compared and magnifi cation amplified on the next etching is corrected. CONSTITUTION:A spectral intensity waveform is amplified by a photoelectric conversion amplifying section 10 until an intensity at a point A reaches a fixed value (a), magnification (n) at that time is obtained, a stable point B during etching is determined by the spectral intensity waveform amplified, and the time T2 up to a point B from the start point of etching is acquired. The quantity of offset is added to the spectral intensity waveform so that intensity at the point B reaches a zero level by an offset circuit 20, a stable point C where etching is completed is decided by the spectral intensity waveform after offset, and the time T3 up to the point C from the start point of etching is obtained. The spectral intensity waveform after offset by a signal amplifying circuit 30 is amplified until the intensity at the point C reaches a fixed value (b) and magnification (m) at that time is acquired, and the point of inflection is obtained by primary differentiation, secondary differentiation or the like and a value required for detecting the end point of etching is set. Accordingly, the end point can precisely be decided even when the number of treatment progresses.

Title: Discharge lamp lighting transformer and discharge lamp lighting device
Inventor: SAKAMOTO MAMORU
IPC: H01F38/08
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting transformer and a discharge lamp lighting device capable of eliminating the need for a ballast capacitor between a discharge lamp and the secondary side of the transformer. SOLUTION: A high-tension transformer has load characteristics set to put the impedance of a discharge lamp to be lit, when normally lit, into a load area (a decrease area), where the primary inductance of the transformer is decreased. By using the load impedance of the high-tension transformer to light the discharge lamp, a discharge lamp lighting device develops high voltage when the discharge lamp is initially lit and drives in the decrease area of the high-tension transformer when normally lit, thus to eliminate the need for a ballast capacitor.

Title: Magnetic recording and reproducing device
Inventor: TAKEGUCHI YORIYASU
IPC: G11B20/18
Filed: 1984-04-18
Abstract: PURPOSE:To minimize the deterioration of sound quality and to execute special reproduction by providing a speed control circuit which fixes the ratio between the number of cylinder revolutions and the feed speed of a recording medium, and an output control circuit which outputs the PCM data reproduced in response to the degree of acceleration/deceleration after thinning or interpolating a part of said PCM data. CONSTITUTION:When a changeover switch 24 is switched in a double speed reproduction mode, a speed control circuit 23 produces a pulse of a double frequency as a control signal of a cylinder motor 21 as well as the control voltage of a capstan motor 22 to double the feed speed of a capstan 7. An output control circuit 26 samples the outputs of a signal processing circuit 25 every second one and sends them to a D/A converter 27. Then the switch 24 is switched again for the 1/2 speed reproduction, and a pulse of a 1/2 frequency is produced as a control signal of the motor 21. At the same time, the feed speed of the capstan 7 is slowed down to half. The circuit 26 transfers the original data as well as the data obtained by interpolating mean value to the original data to the converter 27 by the signal given from the circuit 23.

Filed: 1978-06-29
Abstract: PURPOSE:To make it possible to detect fallen bottles irrespective of the number of rows of the bottles being carried by detecting the fallen bottles through the surface reflection of the drum portions thereof. CONSTITUTION:A horizontal beam 7 is arranged at a right angle with respect to the conveying direction of a conveyor 6 by which a number of rows of bottles 17 and 17a are conveyed. A supporting member 11 is supported in a reciprocal manner within the guide groove 8 of the horizontal beam 7. The aforementioned supporting member 11, to which are attached a projector and a receiver 16, is moved back and forth at a right angle with respect to the conveyor 6 and is illuminated by the projector 15. The projector 15 and the receiver 16 are arranged such that the uppermost point of the drum portion of the fallen bottle is used as a reflecting point 18 and that the angle of projection theta1 and the angle of reflection theta2 become equal. When the light projected from the projector 15 hits a portion other than the point 18, the quantity of the light to enter the receiver 16 is reduced because the height of the reflection is different. On the contrary, for the fallen bottle, the quantity of the light to enter the receiver 16 is not reduced so that the fallen bottle can be detected.
