Title: Heating method for plastic film
Inventor: OTAKI TOSHIHIRO
IPC: B29C71/02
Filed: 1990-07-31
Abstract: PURPOSE:To prevent coating liquid repellence due to the adhesion of low-boiling matter in coating process from occurring by a method wherein the plastic film concerned is heated with rubber rolls, the content of the low-boiling matter at the start of the use of which is below the specified amount. CONSTITUTION:The plastic film concerned is heated with rubber rolls, the surface of each of which is covered by rubber having the content of low-boiling matter of 1.0wt.% or less. Since the low-boiling matter containing in the covering rubber is very little, the low-boiling matter separating out on the surface of the rubber roll is suppressed to very little since the start of the use of the roll. As a result, the amount of the low-boiling matter adhered to the plastic film passing on the surface of the roll is suppressed to very little, resulting in preventing the coating liquid repellence from occurring in the following coating process. Accordingly, the application of coating fluid by the uniform predetermined thickness can be possible since the start of the used of the roll, resulting in preventing defects in coated product from developing.

Title: Rounding device
Inventor: SHIGESATO TATSURO
IPC: H04N19/115
Filed: 1990-07-30
Abstract: PURPOSE:To improve efficiency for high-efficiency encoding using variable length encoding or the like by shifting (n) bits and rounding them after adding 2<(n-1)> when an input signal is a positive number or adding 2<(n-1)> when it is a negative number in the case of rounding the low-order (n) bits of the input signal. CONSTITUTION:This device is provided to round the low-order (n) bits of an input value to be inputted. The input value to be inputted from an input part 1 is inputted to an adder 2 and added to an offset value inputted from an offset input part 4. When the input value is positive, the adder 2 adds 2<(n-1)-1> and when the input value is negative, the adder 2 adds 2<(n-1)> and inputs the value to a shifter 5. The shifter 5 bit-shifts the output of the adder 2 in the direction of the low-order (n) bits and outputs it to an output part 6. Therefore, since an absolute value 0.5 is rounded to 0, the input value is rounded to a basically small value. Thus, efficiency can be improved for high-efficiency encoding using variable length encoding or the like although rounding error is equal to rounding-off.

Title: Molding tool for test resin plate
Inventor: UEHARA HARUO
IPC: G01N1/28
Filed: 1986-08-30
Abstract: PURPOSE:To prepare a large number of test resin plates free from the mixing in air bubbles and having good dimensional accuracy at once within a short time, by injecting a deaerated resin in a mold by pressure difference using a test resin plate molding tool. CONSTITUTION:A liquid resin is put in a resin container 19 and, after deaeration, a resin passage is set so as to be immersed in the liquid resin. When pressure is reduced by a vacuum pump, the liquid resin enters the resin passage and flows to a discharge port 10 while filling a resin filling part 2. When the resin is injected under reduced pressure, the mixing of air bubbles at the time of injection can be prevented. Since the flow of the resin from the discharge port 10 to the reduced pressure side is looked through a glass pipe 17, the reduction in pressure is stopped at a stage wherein the resin flows to the glass pipe 17 to finish the injection of the resin and a press plate 8 with a handle is laid on a support stand 7 and a rubber pipe 8 is detached to cure the resin. After curing, screws 9, 14 are detached to disassemble a molding tool into parts and the test resin plate in a spacer 1 is detached and the part of the resin passage is cut off to make it possible to obtain the test resin plate.

Title: Switching method without transient break
Inventor: SATO YOSHIAKI
IPC: H04L1/22
Filed: 1989-08-07
Abstract: PURPOSE:To switch transmission lines having a large distance difference without a transient break by installing plural systems consisting of transmission systems different in transmission delay time per unit length between plural points and effectively using different transmission systems. CONSTITUTION:At the time of switching a transmission section, a switching device 10 without a transient break on the reception side obtains signals, whose bit phase approximately coincide with each other, from a microwave reception terminal station equipment 8 and an optical communication reception terminal station equipment 9 in the case of Xkm:Ykm=3:2. In the other cases, correction is performed by a phase difference absorbing memory built in a terminal station equipment on the reception side or the device 10 to switch the transmission section. For example, when a current line of the optical transmission system having 400km repeater distance is switched to a stand-by line of the microwave transmission system without a transient break, the number of degrees of freedom of line setting is increased because the stand-by line is capable of by-passing up to 200km besides 400km repeater distance. Different transmission systems are effectively used to switch transmission lines having a large distance difference without a transient break.
