Title: Optical coupler
Inventor: KAKINUMA TAKAYUKI
IPC: G02B6/32
Filed: 1985-09-30
Abstract: PURPOSE:To reduce a relative optical axis shear between collimeters by screwing at least a reference collimeter out of the opposite collimeters on a base plate, adjusting the optical axis of the other collimeter on the basis of the reference collimeter and then fixing the other collimeter. CONSTITUTION:A collimeter 2a is inserted into the recessed part of a fixing block 7 screwed on the base plate 5 with a fixing screw 8. A clamping screw 10 projected to the processed part 9 is clamped from the outside of the fixing block 7 to fix the collimeter 2a by pressing force for screwing. Then, a collimeter 2b is adjusted so that the optical axis of the collimeter 2b coincides with that of the collimeter 2a through an optical transmission medium 6, and after the adjustment, these collimeters 2a, 2b are fixed on the basis plate 5 with a bonding agent 4 through a wedge-like spacer 3.

Title: Mechanism for preventing sag of filter cloth of traveling filter cloth type dehydrator
Inventor: HAYASHI TOMOYUKI
IPC: B30B9/24
Filed: 1982-12-08
Abstract: PURPOSE:To prevent the sag of filter cloths and to normalize the travel of the filter cloths by reversing the filter cloth which is ought to come to the inside just before the filter cloth contacts with the final press roll and sandwiching sludge between the remaining filter cloth and the 3rd filter cloth provided to the above-mentioned roll. CONSTITUTION:Filter cloths 1, 2 are put on many rolls and are turned in an arrow direction. Sludge (m) is chuted and is naturally dehydrated, whereafter the filter cloths 1, 2 are superposed between rolls 4, 5 and 6 and the sludge is dehydrated between press rolls 7, 8...12. The 3rd filter cloth 31 is put on between a final press roll 13 and a roll 30 and the filter cloth 2 is reversed in the direction of a roll 32 just before the filter cloth contacts with the roll 13. On the other hand, the sludge (m) carried on the filter cloth 1 is sandwiched further between the same and the filter cloth 31 and is dehydrated under pressure, whereafter the dehydrated cake (m) is left on the cloth 31 and is again conveyed onto the cloth 2, from which the cake is scraped by a scraper 25. The sage of the filter cloth generating on the inlet side of the final press roll is eliminated by the simple constitution.

Title: Pipe and humidifier and heat exchanger using the same
Inventor: ITO YOSHIHIDE
IPC: F16L11/16
Filed: 1991-08-27
Abstract: PURPOSE:To obtain a pipe at a low manufacturing cost by a method in which the pipe is made of a beltlike tape, which is wound spirally with its side edge doubled, and at least a part of the doubled part of the tape is adhered, so that a peripheral wall of the pipe does not attached to each other when a number of pipes are bundled. CONSTITUTION:A pipe A is formed by winding a beltlike tape T spirally. The tape T is doubled at its side edge part 1, and a doubled part 2 is welded by heat to each other. As a thickness of the doubled part 2 is larger than that of the other part, a peripheral wall 3 of the pipe A expands outside at the double part 2. Accordingly, only by bundling a number of the pipes A with the peripheral walls 3 of the adjacent pipes A contacted with each other at the doubled parts 2 where a diameter is large, a prescribed space S can be procured between the peripheral walls 3 excluding the doubled part 2. If the pipe is employed in a humidifier or a heat exchanger, a humidifying area or a heat exchanging area can be obtained widely.

Title: Vibration reducer for excitation testing apparatus
Inventor: GOTO YOZO
IPC: G01M7/02
Filed: 1987-08-31
Abstract: PURPOSE:To prevent external diffusion of vibration with a simple construction, by oscillating a weight supported with a base block in the direction opposite to an excitation table when a vibration is applied to the excitation table. CONSTITUTION:An excitation jack 24 is driven through a main control unit 26 to apply a vibration to an excitation table 14. A dynamic load of a vibration proof jack 46 by this vibration is computed with an addition/subtraction circuit 56 through an adjusting circuit 54 as output signals of load cells S2 and S3 through an adjusting circuit 54 to oscillate a weight 30 in the direction opposite to the table 14 so that the dynamic load of the jack 46 is canceled. Thus, there is little vibration caused in a base block, thereby eliminating the external diffusion of vibration.

Title: Digital filter
Inventor: HORI MITSURU
IPC: H03H17/02
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To provide the digital filter in which logical compression of a result of multiplication is conducted efficiently. SOLUTION: A fixed coefficient multiplier circuit of the digital filter receives an input X, and multiplies it and provides an output of a result of multiplication. Bits configuring multiplication results Q, S with respect to coefficients '-3', '-5' are respectively digits Q[5] to Q[0] and digits S[5] to S[0]. How the digits Q[5] to Q[0] and the digits S[5] to S[0] are equated to digits X[1], X[0] of the input X are in matching with each other is indicated in logical consistency equations. Some of component digits in both the multiplication results Q, S are included in one logic coincident equation. This means that logic compression is conducted for both the different coefficients '-3', '-5'. Through the constitution above, the logic compression is conducted more efficiently than a conventional processing.  Thus, the scale of a ROM or a decoder circuit being a component of the fixed coefficient multiplier circuit is reduced.
