IPC: B65H1/04
Filed: 1990-08-21
Abstract: PURPOSE:To prevent chattering noise from being generated, when the final sheet is delivered from a sheet supplier, by arranging a slip stop means in a position where no direct contact with a supply roller is provided. CONSTITUTION:When a sheet R2 above the final sheet P3 is delivered by a supply roller 11, the final sheet P3 is pressed to the point end edge of a non-slip pad 14a, pasted in a position where direct contact with the supply roller 11 is not provided, by a step difference and stiffness of the sheet P3. Accordingly, friction force is generated between the final sheet P3 and the point end edge of the non-slip pad 14a, and the final sheet P3 is prevented from being delivered following delivery of the sheet P2 above the final sheet P3. As a result, chattering noise is not generated at all by preventing the final sheet P3 from being directly strongly nipped by the supply roller 11 and the non-slip pad 14.

Title: Fireproof pipe
Inventor: TONO MASAKI
IPC: B32B1/08
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent heat, fire, and smoke generated in one side of a partition part by deformation and burning of a synthetic resin tube constructed in a section pipe passage part in fire, from reaching the other side by setting the thickness of a thermal expansion sheet to a specific numerical value range in the outside diameter of the metal tube. SOLUTION: A fireproof pipe molded into a pipe by laminating a thermal expansion sheet of thickness approximately 2 mm inside the steel plate of thickness approximately 0.3 mm is so arranged as penetrating a section pipe passage part as a sheath for the synthetic resin pipe, a clearance between the fireproof pipe and the section pipe passage part is filled with mortar or the like, tightly closed, and fixed, and the sheath is inserted in its inside. The fireproof pipe is set a little longer than the width of the section pipe passage part and the both ends are so arranged as to be projected to some extent to the both sides of the section pipe passage part.  If the thickness of the thermal expansion sheet becomes thinner, it cannot form a sufficient fireproof expansion layer in fire, and if it becomes thicker, the excessive expansion causes breaking in the fireproof expansion layer so that the thickness of the thermal expansion sheet is preferably set to 1-20% of the outside diameter of the metal tube.

Title: Refrigerator
Inventor: ISHIYAMA OSAMU
IPC: F25D11/00
Filed: 1988-09-03
Abstract: PURPOSE:To make it possible to change the setting of a cooling temperature in a refrigerator, depending on commodities whose refrigeration temperature is different from each other by laying out a plurality of expansion and decompression means between a condenser and a vaporizer in parallel and installing a switching over means which is designed to pass selectively refrigerant to any of the expansion and decompression means. CONSTITUTION:When a paired on/off valve 8B is closed while its paired valve 8A is opened so as to start the operation of a refrigerating cycle 1, refrigerant is fed into a vaporizer 5 by way of an expansion valve 4A and circulates through the refrigerating cycle 1. The air in a refrigerator which circulates in a chilled air circulation passage 15 as indicated by the arrow by a fan 17, is cooled by a vaporizer 5 so that the interior 14 of the refrigerator is stabilized at a cooling temperature which meets the characteristic of the expansion valve 4A. On the other hand, if an attempt is made to send the refrigerant into the vaporizer 5 by way of an expansion valve 4B by closing the on/off valve 8A and opening the on/off valve 8B and circulate the refrigerant, the vaporizer 5 will exert its cooling power, which meets the characteristic of the expansion valve 4B, and cool the air in the refrigerator so that the interior 14 of the refrigerator may be stabilized at a temperature which meets the characteristic of the expansion valve 4B. Therefore, this construction makes it possible to set the temperature in the refrigerator into two different cooling temperatures and take in commodities to be stored at a respective cooling temperature.

Title: Three-dimensional measurement method
Inventor: IWATA YUTAKA
IPC: G01B11/24
Filed: 1992-08-20
Abstract: PURPOSE:To make a method for measurement highly precise and to make a range of measurement wide by a method wherein a slippage of a period of a result of measurement by a measuring means of which the period of a lattice pattern is small is corrected by a result of measurement by a measuring means of which the period is large. CONSTITUTION:A combination of an open pattern 7 with a close pattern 8 of a liquid crystal shutter is made to be of 2 open patterns and two close patterns, for instance. An offset is given to the focus of projection of a measurement reference surface 1 by moving an axial stage 4, patterns of which the distribution of lightness is sinusoidal are projected 3, and the height of an object surface is measured 6 with these measures set as a condition A. Next, the combination of the liquid crystal shutter is made to be of 8 open patterns with 8 close patterns, the lattice patterns of which the period is large are projected 3 by moving the stage 4, and the height of the object surface is measured 3 with these measures set as a condition B. Although the precision of this measurement is lower than that under the condition A, the period of the lattice patterns is four times as large as that under the condition A, the allowance of displacement of the height of the object is four times as wide as the latter and thus accurate correction of the period can be executed. Although the result of measurement under the condition A is highly precise, a measuring point at which the correction of the period fails exists, and therefore the correction is executed by using the result of measurement under the condition B.

Filed: 1992-08-20
Abstract: PURPOSE:To obtain a device having an output circuit adapted to a power supply for operation by forming an output signal in accordance with a potential level of a bonding pad. CONSTITUTION:When PAD 2 is in a low level L, a gate circuit G2 is closed and p MOSFET Q2 keeps an OFF state, but a gate circuit G1 is opened and a signal corresponding to a signal DT is sent to a transistor TrT1. Therefore, when the signal DT is high level H, A signal of H is sent out through the TrT1 and a diode T2. Further, when the signal DT is L and a signal DB is H, n MOSFET TQ1 is made an ON state a signal of L is sent out. When PAD 2 is in a high level H, the circuit G1 is closed and the TrT1 keeps an OFF state, but the circuit G2 is opened and an inversion signal of the signal DT is sent to MOSFET Q2. Therefore, when the signal DT is H, MOSFET Q2 is made an ON state, and an output signal of H corresponding to low power supply voltage is sent out. When the signal DT is L and a signal DB is H, MOSFET TQ1 is made an ON state and an output signal of L is sent out.

Abstract: PURPOSE:To realize the deposition of a non-deteriorating metal film inside a veer hole by a method wherein, after the veer hole has been made at an insulating film by making use of the first resist film as a mask, the surface has been coated with a metal film and the metal film located inside the veer hole has been coated with the second resist film, an excess metal film is removed by etching. CONSTITUTION:By making use of the first resist film 24 as a mask the peripheral edge, to be used to make a veer hole, on the surface of a PSG film 23 is slightly side-etched so as to form a recessed part, and a vertically etched veer hole is made. Then, by leaving the resist film 24 as it is, the surface of the resist film 24 including the veer hole 25 is coated with an aluminum film 26 with a film thickness of more than 1 mum so that the veer hole 25 can be buried. In addition, this assembly is coated with the second and sufficiently thick resist film 27. Then, the second resist film 27 covering the aluminum film 26 located on the resist film 24 is removed so that the aluminum film 26 can be exposed. The exposed aluminum film 26 is removed by etching, and, additionally, the resist films 24, 27 are ashed by means of an oxygen plasma etching process and are then removed. Therefore, the change in quality of the aluminum film 26 which was used to bury the veer hole 25 is not caused.

Title: Liquefaction of coal
Inventor: NAKAKO TAKAO
IPC: C10G1/06
Filed: 1982-12-16
Abstract: PURPOSE:To maintain consistent efficiency of a 2nd-step hydrogenation reaction over a long period in the liquefaction of coal by two-step hydrogenation, by removing alkali (alkaline earth) metal in the products of the 1st-step hydrogenation before the products are passed through the 2nd-step hydrogenation. CONSTITUTION:A slurry consisting of powdered coal A, hydrogenation catalyst C and solent S is hydrogenated in a 1st-step hydrogenation tower 5 and the resultant solvent refined coal (SRC) is hydrogenated in a 2nd-step hydrogenation tower 16 for liquefaction of coal. A guard reactor 20 (operated at about 200- 300 deg.C) packed with an adsorbent 19 (e.g. gamma-alumina or activated carbon) is installed on the upper stream side of the 2nd-step hydrogenation tower 16 to remove alkali (alkaline earth) metal contained in the 1st-step hydrogenation product (SRC) to be fed into the 2nd-step hydrogenation tower. When the SRC contains a large amount of benzene insolubles, it is preferable that an adsorbent which is substantially identical with the 2nd-step hydrogenation catalyst (e.g. Mo-based catalyst) is used and the temperature within the guard reactor is kept at about 330-380 deg.C.

Title: Band-divided transmission system
Inventor: SUZUKI NORIHIRO
IPC: H04N7/12
Filed: 1989-08-30
Abstract: PURPOSE:To reduce folding distortion by dividing signals into plural blocks, sharing several samples on both the ends with the blocks of both the sides, transmitting a signal filtered in extended blocks as a low band signal and directly transmitting samples shared in the blocks as a high band signal. CONSTITUTION:The uppermost lines (block 1: a1 to block n: an) of respective blocks are sent as auxiliary signals. Even when the block 1 is extended up to a2 and the operation of the equation I is applied to the extended block, the original signals can be reproduced on the receiving side because (x1, y1, z1), (a1, a2) are known. Provided that x to y are signals on a panel and a1, d1, a2 indicate scanning lines. When similar operation is executed in respective blocks, the interpolated signals of 3 lines are formed from 5 lines, so that the number of taps can be increased. Consequently, folding distortion can be removed.
