Inventor: NISHIKI TAMAHIKO
IPC: H04B10/564
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a gain equalizer wherein eventual package size is reduced and the effect of vibration on optical characteristics and mechanical reliability is less. SOLUTION: A gain equalizer 100 which equalizes the gain of an optical amplifier comprises long-cycle fiber gratings(LPG) 31, 32, and 33 comprising wavelength characteristics corresponding to gain wavelength characteristics of the optical amplifier connected at front and/or post stage of the gain equalizer 100, a package 10 which houses the LPGs 31, 32, and 33 substantially in parallel, and light reflection members 41-1 and 42-2 which fold back light's advancing direction so that parallel LPGs 31, 32, and 33 are connected in series, are provided.

Title: Magnetic recording and reproducing apparatus
Inventor: KAJINO JIROU
IPC: G11B15/665
Filed: 1977-09-20
Abstract: PURPOSE:To simplify the construction by providing shift varying means for connecting an operating member and a releasing member at two positions. CONSTITUTION:When a second plunger 294 is operated, the angular motion of a lever 332 is so small that a pin 338 releases only the braking force of a take-up reel carriage 40. After magnetic tape extracting means shifts the magnetic tape to a position where the latter is extracted to the outside of a cassette, the second plunger 294 is operated. In this instance, a pin 310 is located in a narrower portion of the stepped hole of the lever 332, the rotations of the lever 32 are so enlarged that the pin 338 releases the braking forces of both the reel carriage 40 and a supply reel carriage 38. Thus, the rotations of the lever, which is driven by the second plunger 294, are made so variable that only the braking force of one of the reel carriages is released, thus simplifying the construction.

Title: Ventilator
Inventor: MOCHIZUKI TSUTOMU
IPC: E03C1/122
Filed: 1992-05-06
Abstract: PURPOSE:To prevent bad odor from leaking to the outside by a method wherein the interior of the title device is isolated from the outside when the interior is under positive pressure, and deformation is made so that the capacity of a variable space communicated with the interior space can be made large. CONSTITUTION:In the case where an interior space 11a of a ventilator body 11 is under stationary pressure, an opening 12 of a valve 13 is closed. At this time, the pressure in a space 17a communicating with the outside air becomes higher than the pressure in a space 17b communicating with the interior space 11a, and thereby a partitioning material 18 is deformed so that the volume of the interior space 11a can be enlarged. The capacity of the largely deformed space 17b is set so that it can absorb the amount of exhaust from a vent pipe 3. In the case where the interior space 11a of the ventilator body 11 is under negative pressure, the inside air is put back to the ventilator body 11 after making the volume of the variable space small, and thereby leakage of bad odor from the exhaust can be prevented.

Title: Envelope for funeral offering
Inventor: INOUE SATOSHI
IPC: B65D27/00
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To make a name or the like on an envelope for funeral offering appear to have been written in Chinese ink to be in accord with social manners. SOLUTION: Water-repellent treatment is applied on a range of a column 4 for writing a name or the like of an envelope for funeral offering, whereby even if a user writes the name or the like 5 here in thick Chinese ink, it may appear as if it were written in thin ink. Thus it necessarily brings smooth association with politeness to a recipient. The range for water-repellent treatment may also cover columns for an offering sum and an address on a back side. Although water-repellent treatment can be done by spraying water repellent for waterproof treatment, a water-repellent treatment process may be incorporated during machining processes such as printing, embossing or cutting for mass production.
