Title: Power unit
Inventor: MAEHARA MINORU
IPC: H02M7/5387
Filed: 1993-10-26
Abstract: PURPOSE:To suppress the occurrence of input current distortion and rush currents and, at the same time, to make control easier by operating a voltage drop chopper for suppressing the occurrence of rush current at the time of making power supply and a voltage boost/drop chopper for improving input current distortion in a steady state. CONSTITUTION:A smoothing DC power source circuit suppresses the occurrence of a rush current after making power supply by operating a voltage drop chopper and improves input current distortion by operating a voltage boost/drop chopper. The switching between the choppers is automatically performed on the basis of the relation between the magnitudes of an input voltage Vin and the DC voltage Vdc of a capacitor C1. Therefore, the circuit configuration of the circuit does not become complicated and the size and cost of the circuit can be reduced. In addition, since the voltage drop chopper is used for suppressing rush currents and, when a transistor Q2 is turned on, an input current flows while charging the capacitor C1, the current of an inductor L2 gently rises. Therefore, the turning off time of the transistor Q2 can be shortened and the control of the transistor Q2 becomes easier.

Title: Flame detector
Inventor: KAWAKAMI YUICHI
IPC: G08B17/12
Filed: 1987-10-22
Abstract: PURPOSE:To accurately judge the presence of a flame even when disturbing light of frequency higher than the frequency of fluctuations of the flame is incident by providing a frequency discriminating circuit in front of a counter. CONSTITUTION:The time width (t) of a pulse is set in relation t=1/2Fmax with the maximum value Fmax (about 20-30Hz) of the frequency F of the fluctuations characteristic to the flame. Consequently, the output c2 of the frequency discriminating circuit 38 becomes a pulse train when the frequency of the output (a) of an amplifier 3 is lower than the frequency Fmax, but no pulse train is outputted when the frequency of the output (a) is higher than the Fmax. Consequently, when the frequency of the fluctuations of the disturbing light exceeds the frequency of the fluctuations characteristic to the flame, no pulse train appears at the output of the frequency discriminating circuit 38, so as warning output (h), so the counter 31 does not count up and generate no 'H' output (g), so a warning output (h) is not sent out regardless of the outputs (f) and (f1) of the comparing circuits 27 and 29. The flame is therefore securely detected.

Title: Multiple optical fiber tape with two-dimensional array optical connector, its manufacturing method and retaining member, for multiple optical fiber tape
Inventor: SHIDA TOMOHITO
IPC: G02B6/40
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of buckling bending in the inner optical fiber tape based on the difference of inner-outer rings of respective optical fiber tapes when the optical fiber tapes whose superposed intermediate parts are retained are bent. SOLUTION: The proper parts in the length direction of the two superposed optical fiber tapes 1 are retained by retaining members 12 while shifting the two optical fiber tapes with each other in the width direction of the tape. On the tip of the tape, a ferrule 4 having optical fiber holes of two-dimensional array (in this case, optical fiber holes which are arranged in transverse two rows) is attached. As the two optical fiber tapes 1 are mutually shifted in the width direction of the tape, the two optical fiber tapes 1 do not form the inner- outer rings to each other when the double optical fiber tapes 15 with an optical connector are bent. When the tapes 15 are bent, therefore, the buckling bending due to the difference of the inner-outer rings does not occur in the inner optical fiber tape 1.

IPC: H01L31/04
Filed: 1990-10-05
Abstract: PURPOSE:To get a solar battery element with high conversion efficiency, wherein the loss by current collecting resistors at the rear of an element is reduced and light shut-in effect is improved, by forming the p-type silicon substrate and the p<+>-layer in the region surrounded by a mesh-shaped electrode in the shape of grooves crossing each other at right angles. CONSTITUTION:By providing grooves 16, which cross each other at right angles, in the region, which is surrounded by the mesh-shaped Ag electrode 10 made at the rear of the element of a p-type semiconductor base layer 12, opportunity increases such as that one part of the light, which has entered the light receiving face of a solar battery 1, reaches the rear and is reflected at the rear, and that one part of the light, which has gone out of the side of the groove, enters the bottom of the groove or the side of other groove again, so the utilization factor of the incident light rises. Moreover, in the p<+>-type semiconductor layer 11 at the rear, the sectional area to the direction of an electrode increases, and the loss by current collecting resistors decreases. Furthermore, in the groove part 16, the depth is approximately 30mum, so the effective thickness of the substrate is approximately 170mum, and the effect of collecting the light generating carriers improves in the region near the junction of the light receiving face without thinning the real thickness of the substrate.

IPC: G09G5/36
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent fog or unsharpness of a character outline in a magnified image by deciding the density of a magnified picture element to be interpolated based on a density change between intermediate original picture elements among four consecutive picture elements. SOLUTION: Flip-flop circuits 1a, 1b, 1c, 1d store tentatively density data of four consecutive original picture elements on a same line of a magnification object image tentatively and respectively. A discrimination means 2 discriminates whether or not a density change in any of the original picture elements is specific and consists of discrimination means 2a or 2b discriminating whether or not a density change in the original picture elements is specific especially. A function generating means 3 generates a scheduled function depending on the result of discrimination by the discrimination means 2, and a density setting means 4 sets a density of the magnified picture element to be interpolated to the original picture element in response to the magnification based on the generated function. Thus, the magnification processing with fidelity to the original image is attained.
